yonbergman / enumify Goto Github PK

If I have an enum with :allow_nil => true, then it can be read from the db as nil, but I cannot set the field to nil using update or simple assignment (=).

If I try to do that I get: NoMethodError: undefined method to_sym' for nil:NilClass`

after upgrading to rails 4 i prefer to keep using enumify. how would you do that?

The reason is because Rails 4's enum are based on integers and persist the ordinal number of the enum value, unlike enumify which persists the string value. so its a hassle to update the models.

class Partners::Contact < ActiveRecord::Base
enum :status, [:pending, :active]
end

rails s
$ h.contacts.first.status
NoMethodError: undefined method empty?' for 1:Fixnum from /Users/volte/a2/vendor/bundle/gems/enumify-0.0.5/lib/enumify/model.rb:11:inblock in enum'
from (irb):6

This gem is exactly what I've been looking for. Sorry to post this in issues, but heck if I can find a better place to ask questions.

What's the best way to get the index of the value in an enumify field? In my projects, I frequently do things like:

if status_index > 2; something; end

where status_index is the value index according to a mysql query on the enum field

select status+0 status_index from orders...

I also do things like

self.status = 2
save

What about ActiveRecord queries with an enumify field in the :conditions?

:conditions=>{:status=>"submitted"}

or

:conditions=>"orders.status > 2"

Thanks!
