Versioned database functions and triggers for Rails
License: MIT License
As Rails 6 is shipped(#39) - we want to drop support for Rails 4.2 and ruby versions older than 2.2.2.
I don't know if it best in here or in
https://github.com/ctran/annotate_models/
Basically it will be nice if we can see triggers in model. So that we are aware of their existence.
When trying to run a simple generate
command based on the README
rails generate fx:trigger uppercase_user_name
I am seeing the following output:
No value provided for required arguments 'table_name'
It's not clear based on the documentation what table_name
is.
Any ideas?
I expect not much has changed from 5.0 to 5.1 and 5.2. But - we should add them to our test suite.
As we've begun adding functions to our system we've found a minor but annoying pain point when updating functions. With the current behavior a call to update_function
will first drop and then recreate the function. For simple use-cases this behavior works fine, but as your functions grow and begin to depend on each other this no longer works. The problem becomes worse with the addition of views through the scenic gem.
As an example, imagine this scenario:
age_years(dob date) returns int8
for calculating the number of years since dob
.age_bracket(dob date) returns text
returning a string of "child", "adolescent" or "adult" using age_years
.age_years(dob date)
and age_bracket(dob date)
.In the current system we have two options:
CREATE OR REPLACE FUNCTION
in our function definitions, and in the migrations manually execute the correct up and down versions.My current thinking is that adding a replace_function
for migrations, with a generator flag --replace
, would be enough to completely support these scenarios. Perhaps even make the default replace_function
and keep the "tear it all down" update_function
approach for when actually needed.
An alternative, that I don't like as much, would be changing update_function
to "realize" when a script has OR REPLACE
and skip dropping those functions. Although instead of a new replace_function
method we could add the flag replace: true
to this method instead.
Hey there!
I was wondering if this gem has any options as far as code formatting (tabs/spaces, number of spaces/tabs) as far as when code is inserted into schema.rb. I took the time to format the SQL how I preferred it to be - but whenever we run a migration, it is overwritten with the default/original formatting.
Feel free to just tell me "no", and I will happily live with it how it is.
Thank you!
Could you add a section in the README on how to update a function that's used by triggers to not get errors while migrating, please?
Hello, thanks for this gem!
The create_function
and create_trigger
commands both accept a version
argument, but when you roll back the migration you get this failure, because drop_function
and drop_trigger
don't know about that param:
ArgumentError: unknown keyword: version
(I'm not really sure why create_
commands would need a version other than 1
, but I guess someone must be using it.)
I can see that you're already trying to make these commands reversible. Would you be interested in a PR that knows how to reverse creating functions & triggers when given a version? I guess it would still just DROP
them.
I use hair_trigger
in a project to add triggers which are integral to the DB -- it's used enough that I wrote some basic versioning around it, inspired by scenic
(which seems v similar to the system fx
uses).
Yesterday, I was looking for a way to add functions via migrations. Using execute
works for rails db:migrate
but doesn't work for tests because schema.rb doesn't record the functions. I couldn't find a way to force the execute
SQL to be included, so went looking for a gem that could do this for me and found fx
-- great!, I thought. However, fx
defines create_trigger
, which hair_trigger
also defines. this has been problematic.
I tried a few things, like 'fx', require: false
in the gemfile and then require 'fx'
(and some variants like require 'fx/functions', and
include Fx::Statements::Function` in the migration) but couldn't get anything working. Searching (many times in different ways) for methods to avoid naming conflicts between gems did not yield useful results.
my (eventual, and very quick) solution was to fork this repo and just comment all the requires and methods regarding triggers, which works well, but isn't really a good, long term, principled solution to the problem.
The main idea on how to solve this that I have atm is for fx
to provide either:
trigger
or function
related statements/adapters (this does not look that simple, but mb there is an elegant way to do it), maybe via 'fx', require: 'function'
in a gemfile; orfx_create_function
and fx_create_trigger
, then maybe have 'fx', require: 'compatibility_names'
in the gemfile, or something.I think method 1
might be mb an easier PR, but there's a decisive reason to go with method 2
, IMO: I want to start using fx
for triggers instead of hair_trigger
-- and that probably requires having both gems loaded simultaneously. I don't think it's a good idea to try and remove hair_trigger
from past migrations (the webapp isn't live, yet, so this is maybe feasible); the more principled approach feels like going for compatibility over partial requires.
If I write a PR for this, is this something that would be merged? (after review, etc)
If so, do you (or does anyone else) have any useful insight/input to this problem and other methods of solving it?
Finally, do you have any hints about how I should approach this? like, where would the best places be to add this sort of thing. I guess that I will need to learn a bit more about gemfiles and requires, but it doesn't seem overly complex.
here is my_code

With Rails 6 just being shipped, is there anything we can do get fx to work with the new version?
Hi!
I see that the gem already support Ruby 3, but the release on rubygems doesn't support it (crash when reverting migrations). A ruby 3 compatible release would be helpful.
Is the gem in a releasable state?
Hey!
We use this gem in combination with https://github.com/rails-on-services/apartment. Like that gem recommends, we install extensions into a separate schema that is used throughout the application. We would also like to be able to create function in a different schema than the public one, eg:
CREATE OR REPLACE FUNCTION shared_extensions.my_function(...
The "creating" part works as expected, but because this line is hardcoded to look into the public schema, the functions aren't dumped to the schema.rb
.
fx/lib/fx/adapters/postgres/functions.rb
Line 22 in 94b4997
Would you be open to adding a way to configure the schema lookup?
While the gemspec claims the gem is licensed under the MIT licence, the recently added LICENSE file declares BSD-3. Which is it?
See #122, once activerecord is warning free this should be done and dealt with.
Thanks for this, as a user of scenic, I was happy to find a similar tool for functions :)
Unfortunately, this doesn't work for functions with parameters: although creating function isn't a problem, dropping function isn't possible so migrations can't be reverted.
I believe the problem comes from Fx::Adapters::Postgres#drop_function as the brakets (()
) are added automatically.
I have functions with parameters and the function signature must be specified to drop it (because one can create different functions with the same name but different parameters).
A fix could be that when the function name is specified as a string, the brackets are not added? If backward-compatibility is a concern, the alternatively could be to pass a list of parameters as an option?
I don't use Hound that much nowadays, might change F(x) to use CodeClimate instead.
Hi!
drop_trigger does not work with Ruby 3. Unfortunately, I couldn't make a quick fix for this.

This was brought up in #73, and I think it holds some merit if we include a generated boilerplate with the generated function and/or trigger. Ideally this generated boilerplate should be unique per database adapter.
I've been pretty good at writing release notes in the version bump commit, so migrating to a changelog file should be easy enough to do.
I don't know what then naming convention is of these files, but something conventional.
I think the right way to set up triggers with fx is like: (after running fx:function
and then fx:trigger
generators)
db:
functions:
- do_the_thing_on_insert_v01.sql # `CREATE OR REPLACE FUNCTION ...`
triggers:
- do_the_thing_on_insert_v01.sql # `CREATE TRIGGER do_the_thing_on_insert AFTER ...`
then after running rails g fx:function do_the_thing_on_insert
we have:
db:
functions:
- do_the_thing_on_insert_v01.sql # `CREATE OR REPLACE FUNCTION ...`
- do_the_thing_on_insert_v02.sql # `CREATE OR REPLACE FUNCTION ...`
triggers:
- do_the_thing_on_insert_v01.sql # `CREATE TRIGGER do_the_thing_on_insert AFTER ...`
with the migration:
class UpdateFunctionDoTheThingOnInsertToVersion2 < ActiveRecord::Migration[6.1]
def change
update_function :do_the_thing_on_insert, version: 2, revert_to_version: 1
end
end
that looks mb okay, but running it gives the error:
ActiveRecord::StatementInvalid: PG::DependentObjectsStillExist: ERROR: cannot drop function do_the_thing_on_insert() because other objects depend on it
DETAIL: trigger do_the_thing_on_insert on table things depends on function do_the_thing_on_insert()
HINT: Use DROP ... CASCADE to drop the dependent objects too.
I was hoping that the CREATE OR REPLACE FUNCTION
thing would just work out, but apparently not. So the workaround I initially came up with was:
class UpdateFunctionDoTheThingOnInsertToVersion2 < ActiveRecord::Migration[6.1]
def change
drop_trigger :do_the_thing_on_insert, on: :things, revert_to_version: 1
update_function :do_the_thing_on_insert, version: 2, revert_to_version: 1
create_trigger :do_the_thing_on_insert, on: :things, version: 1
raise "if we get here, the migration worked but don't commit the result, yet"
end
end
however, this doesn't feel great, and only migrates correctly in the fwd direction. in the reverse I get:
-- drop_trigger(:do_the_thing_on_insert, {:on=>:things, :version=>2})
rails aborted!
StandardError: An error has occurred, this and all later migrations canceled:
wrong number of arguments (given 2, expected 1; required keyword: on)
I can go the whole
reversible do |dir|
dir.up do; end
dir.down do; end
end
But IDK if that's the intended way to do this sort of thing with fx. I had a look at other issues but didn't find anything.
Is there a better way to do this sort of thing? (or am I doing something wrong and can avoid this by doing something different?)

This throws the following error if you have aggregate functions (Postgis has a lot of these):

Basically pg_get_functiondef()
fails for aggregate functions.
Currently if you run the generator with the following for example
rails generate fx:function test
The generator will create a migration file and an sql function file with paths like the following
db/functions/test_v01.sql
db/migrate/20211011202933_create_function_test.rb
But when you try to destroy the generated files with the following commad
rails destroy fx:function test
The generator tries to remove files with paths that don't exist like the following
db/functions/test_v02.sql
db/migrate/20211011203016_update_function_test_to_version_2.rb
GEM VERSION 0.6.2
Hi! Thanks for all your work on this gem. We ran into an issue where the schema dumper would occasionally dump the functions in a different order, resulting in a diff that didn't really reflect any changes. Our workaround is something like this:
# This monkey patches the F(x) gem so that the functions are always dumped in
# alphabetical order by name, preventing schema diffs when nothing has actually changed.
# Original code: https://github.com/teoljungberg/fx/blob/master/lib/fx/schema_dumper/function.rb
module Fx
module SchemaDumper
module Function
def functions(stream)
dumpable_functions_in_database.sort_by(&:name).each do |function|
stream.puts(function.to_schema)
end
end
end
end
end
It could also be done in the dumpable_functions_in_database
method though. If other people have this issue or if you think it would be helpful, I'd be happy to open a PR along these lines.
It would be amazing if fx supported procedures!
I would love to be able to say
rails g fx:procedure my_fancy_procedure
Because I accidentally tried to do that with a procedure and use create_function
/ update_function
and boy did that not work (because of course it isn't supported yet).
I love this gem!
Travis is no longer free from open source, and I had totally missed that. We should replace it with something else, and #40 (comment) brought up that we could replace it with GitHub actions.
I'm OK with that, and would welcome a PR.
Ruby's EOL is <= 2.6, we should drop the versions older than that, and ensure that 2.7 and above are supported.
AFTER INSERT OR UPDATE OR DELETE
ON table_name
FOR EACH STATEMENT
WHEN (OLD.value IS DISTINCT FROM NEW.value)
EXECUTE PROCEDURE function();
Could someone make it work?
The gem currently doesn't have a wiki, meaning that users have to figure out how to use the gem from:
It would be amazing to have some wiki pages explaining the different things that can be achieved with the gem, and the different options that can be used in each situation.
Hi. Thanks for making fx
! it helped me clean up the company's big rails app's migrations quite a bit.
Sadly, we still have to use db/structure.sql
.
I'd prefer if we could go back to using db/schema.rb
.
The one last thing that stands between here and there is a custom operator.
Currently, we have this code in the same migration with all of our create_function ...
calls:
# TODO: figure out if/how we can express this so it ends up in schema.rb:
execute <<~SQL.squish
CREATE OPERATOR ||+ (LEFTARG = TEXT, RIGHTARG = TEXT, PROCEDURE = immutable_concat);
SQL
I'd rather have:
create_operator :pipe_pipe_plus
This line of code:
CREATE OPERATOR ||+ (LEFTARG = TEXT, RIGHTARG = TEXT, PROCEDURE = immutable_concat);
is depended on by a few lines of code in migrations like this:
t.index "(((((name)::text ||+ (location_line_1)::text) ||+ (location_city)::text) ||+ (location_region)::text)) gin_trgm_ops", name: "index_jobs_1_gin", using: :gin
I tried, just in case, doing a create_operator :pipe_pipe_plus
along with all of our create_function
s.
This raises a NoMethodError
for #create_operator, obviously.
I tried being sneaky and doing create_function :pipe_pipe_plus
.
This didn't blow up, but then didn't end up in db/schema.rb
.
I'm assuming that this is because db/schema.rb
has no concept of create_operator
like it has create_function
, create_trigger
, create_view
, et al (?).
Could you add a create_operator
method that works just like create_function
, which looks for a file named the same as the passed in symbol arg but in a db/operators
folder instead of db/functions
?
And then :hand wave: (I don't know what this would take), also get that to work in db/schema.rb
please?
That would make me so happy.
When I generate a function with the generator such as in the example;
rails generate fx:function uppercase_users_name
it only generates the function but not the migration file. Reverting to 0.5 solved the issue
Nothing drastic has changed, but for safety's sake I'd like to be able to easily add new Ruby versions to build matrix as the are shipped.
In the app I work on we have quite a lot of functions and it is becoming very messy and difficult to maintain. It would be great if the gem allowed me to specify a subfolder that a function belongs to so that I can place functions into subfolders to categorise them. Ideally this could be done by adding an option to the create_function
method to specify the subfolder name.
We start using Fx on a database using PostGIS.
When performing rails db:schema:dump
, fx is dumping a trigger from the topology extension:
ActiveRecord::Schema.define(version: 2022_11_29_082047) do
enable_extension "postgis"
enable_extension "postgis_topology"
(...)
create_trigger :layer_integrity_checks, sql_definition: <<-SQL
CREATE TRIGGER layer_integrity_checks BEFORE DELETE OR UPDATE ON topology.layer FOR EACH ROW EXECUTE FUNCTION topology.layertrigger()
SQL
end
After then, any rails db:schema:load
will fail.
$ rails db:schema:load
rails aborted!
ActiveRecord::StatementInvalid: PG::DuplicateObject: ERROR: trigger "layer_integrity_checks" for relation "layer" already exists
The trigger is dumped by the statement defined in (..)/adapters/postgres/triggers.rb :
# SELECT * FROM pg_trigger WHERE pg_trigger.tgname NOT ILIKE '%constraint%';
oid | tgrelid | tgparentid | tgname | tgfoid | tgtype | tgenabled | tgisinternal | tgconstrrelid | tgconstrindid | tgconstraint | tgdeferrable | tginitdeferred | tgnargs | tgattr | tgargs | tgqual | tgoldtable | tgnewtable

(1 row)
I tried but couldn't find a way to link triggers to namespaces to include only "public" triggers as is done for functions.
Fails on cloud providers not using a standard local postgres socket
I looked at #create_trigger
method code and noticed than option on
not used in code. I tried run my migration without this option and migration successful done.
Is option on
for #create_trigger
useless? What do you think about using this option to interpolate sql definition?
For example:
CREATE TRIGGER update_state_changed_at
BEFORE UPDATE ON %{on}
FOR EACH ROW
WHEN (OLD.state <> NEW.state)
EXECUTE PROCEDURE update_state_changed_at();
I think this is easy and I can make pull request if you don't mind
Hi! not sure if I'm missing something (maybe a config or similar) but when a project uses table_name_prefix
(or table_name_suffix
) on the application.rb
, like:
module ProjectName
class Application < Rails::Application
# ...
config.active_record.table_name_prefix = 'project-prefix-'
# ...
end
end
Seems that the generated functions
or triggers
should be aware of, in such the seems to need to generate the files like:
/functions/project-prefix-logidze_capture_exception_v01.sql
...
/triggers/project-prefix-logidze_on_some_table_v01.sql
And as metioned in the Issue #207 on the logidze gem this issue is related to how fx
implemented the create_function
method. It is though the method_missing
defined in activerecord-6.1.4.4/lib/active_record/migration.rb:915 and so in there the method proper_table_name( )
is called, and in such when you have in the migration:
#...
dir.up do
create_function :logidze_capture_exception, version: 1
end
#...
When the migration is run, the file that looks for is functions/project-prefix-logidze_capture_exception_v01.sql
and the same happes with the triggers so if in the migration there is:
#...
dir.up do
create_trigger :logidze_on_some_table, on: :some_table
end
#...
The file that looks is triggers/project-prefix-logidze_on_some_table_v01.sql
and notice that the second argument is fine because the same proper_table_name( )
is called on them so the actual table name is referenced, in this case project-prefix-some_table
Not sure if this is something that you have in mind or do you want to address it. If so, what approach do you prefer?
Thanks for all the work you put into this gem!
We are experiencing a problem with the way the dump is generated into the schema.
Generated schema puts function definitions at the bottom
ActiveRecord::Schema.define(version: 2019_06_04_171454) do
# These are extensions that must be enabled in order to support this database
enable_extension "plpgsql"
enable_extension "unaccent"
create_table "products", force: :cascade do |t|
t.string "name"
t.index "ts_tokenize((name)::text)", name: "index_product_name_tokenized", using: :gin
end
create_function :ts_tokenize, sql_definition: <<-SQL
CREATE OR REPLACE FUNCTION public.ts_tokenize(text)
RETURNS tsvector
LANGUAGE sql
IMMUTABLE
AS $function$
SELECT to_tsvector(public.unaccent('public.unaccent', $1))
$function$
SQL
end
This creates a failure when loading the schema at our test suite because it tries first to create the index depending in the function that was not defined yet.
If we manually change the order, and define the function just after enabling extensions we experience no problem at all, but every migration/dump resets the default order making this fail.
Probably a fix for this might be defining the functions at the beginning of the schema in order to have it available for the rest of the code.
Thank you.

Here is a copy of my schema https://gist.github.com/cj/bb62776913387c17ca1dc9c1c3ae394c
Locally it is working fine, the problem seems to just be when running it on github actions. Here is a copy of my github action https://gist.github.com/cj/ba6aca746cbc84afba1a1b510979889d
If this is unrelated to FX please let me know and I can close the issue.
Cheers!
I'm not sure if I'm doing something wrong, but when I have a trigger such as the following, under db/triggers:
CREATE TRIGGER trigger_name
BEFORE INSERT OR UPDATE ON table_name
FOR EACH ROW EXECUTE PROCEDURE
function_name();
With a migration as follows:
class CreateTriggerTriggerName < ActiveRecord::Migration[5.2]
def change
create_trigger :trigger_name, on: :table_name
end
end
Running the migration adds the trigger to the schema, but converts the PROCEDURE
to a FUNCTION
, as follows:
create_trigger :trigger_name, sql_definition: <<-SQL
CREATE TRIGGER trigger_name BEFORE INSERT OR UPDATE ON public.table_name FOR EACH ROW EXECUTE FUNCTION function_name()
SQL
Is this expected behaviour? Is there any way to override/prevent it? Our app needs a PROCEDURE and not a FUNCTION to be run by the trigger.
create_function :naturalsort, sql_definition: <<-SQL
CREATE OR REPLACE FUNCTION public.naturalsort(text)
RETURNS bytea
LANGUAGE sql
IMMUTABLE STRICT
AS $function$
select string_agg(convert_to(coalesce(r[2], length(length(r[1])::text) || length(r[1])::text || r[1]), 'SQL_ASCII'),'\x00')
from regexp_matches($1, '0*([0-9]+)|([^0-9]+)', 'g') r;
$function$
SQL
notice the \x00
I think it should be escaped in the generated schema.rb.
It works if we use structure.sql .
The specs fail when run on a more recent version of Postgres than 10.x, which EOLs this year. There are currently four more recent major versions - 11 - 14.
The failure is due to a change in syntax for trigger creation. In Postgres 10.x, the text EXECUTE PROCEDURE
was included, as can be seen here - https://www.postgresql.org/docs/10/plpgsql-trigger.html
In later Postgres versions, this text was changed to EXECUTE FUNCTION
as can be seen:
This mismatch causes specs to fail.
Is there any objection to updating the Postgres version in .travis.yml to 14? Making this change doesn't appear to impact the behavior of the gem, only whether the specs pass.
4.0 and 4.1 have reached EOL, we can comfortably drop them.
