`datasette publish` needs support for the new config/metadata split about datasette HOT 12 OPEN

Once I have this working I should use it to ship a demo of a datasette.yml file somewhere, so I can then add a link to that demo to the new documentation for:

• #2254

It should go in this section: https://docs.datasette.io/en/latest/introspection.html#config

from datasette.

As soon as datasette publish cloudrun has this I can re-enable this bit of the demo deploy:

Which should fix this broken demo from https://simonwillison.net/2022/Dec/2/datasette-write-api/

https://todomvc.datasette.io/

from datasette.

The @add_common_publish_arguments_and_options decorator described here is bad. If I update it to support a new config option all plugins that use it will break.

I want to deprecate it and switch to a different, better design to address the same problem.

from datasette.

I think the actual design of this is pretty simple. Current help starts like this:

Usage: datasette publish cloudrun [OPTIONS] [FILES]...

  Publish databases to Datasette running on Cloud Run

Options:
  -m, --metadata FILENAME         Path to JSON/YAML file containing metadata
                                  to publish
  --extra-options TEXT            Extra options to pass to datasette serve

The -s and -c short options are not being used.

So I think -c/--config can point to a JSON or YAML datasette.yaml file, and -s/--setting key value can mirror the new -s/--setting option in datasette serve itself (a shortcut for populating the config file directly from the CLI).

Here's the relevant help section from datasette serve:

  -m, --metadata FILENAME         Path to JSON/YAML file containing
                                  license/source metadata
  -c, --config FILENAME           Path to JSON/YAML Datasette configuration
                                  file
  -s, --setting SETTING...        nested.key, value setting to use in
                                  Datasette configuration

from datasette.

I'd really like to remove --extra-options. I think the new design makes that completely obsolete?

Maybe it doesn't. You still need --extra-options for the --crossdb option for example.

from datasette.

https://github.com/search?q=datasette+publish+extra-options+language%3AShell&type=code&l=Shell shows 17 matches, I'll copy in illustrative examples here:

--extra-options="--setting sql_time_limit_ms 5000"
--extra-options="--config default_cache_ttl:3600 --config hash_urls:1"
--extra-options "--setting sql_time_limit_ms 3500 --setting default_page_size 20 --setting trace_debug 1"
--extra-options="--config default_page_size:50 --config sql_time_limit_ms:30000 --config facet_time_limit_ms:10000"
--extra-options="--setting sql_time_limit_ms 5000"
--extra-options "--setting suggest_facets off --setting allow_download on --setting truncate_cells_html 0 --setting max_csv_mb 0 --setting sql_time_limit_ms 2000"

from datasette.

Found more when I searched for YAML.

Here's the most interesting: https://github.com/labordata/warehouse/blob/0029a72fc1ceae9091932da6566f891167179012/.github/workflows/build.yml#L59

--extra-options="--crossdb --setting sql_time_limit_ms 100000 --cors --setting facet_time_limit_ms 500 --setting allow_facet off --setting trace_debug 1"

Uses both --cors and --crossdb.

from datasette.

Maybe I should add --cors and --crossdb to datasette publish cloudrun as well?

from datasette.

Worth noting that it already sets --cors automatically without you needing to specify it:

I wonder if that's actually surprising behaviour that we should change before 1.0.

Hi @simonw,

Awesome work with Datasette as always. We talked previously with a colleague about a project we were interested in hosting on Datasette Cloud. While waiting for DS Cloud to be ready, we decided to publish Datasette ourselves first. We were able to deploy the latest version (1.0a13) on Google Cloud Run but I did notice that datasette publish did not support an option for the datasette.yaml/json.

Because of this, our deployed instance lacked features that are available when ran locally. Specifically, the config/options (previously in metadata.yaml) that were moved to datasette.yaml that our instance is lacking are:

• extra_css_urls (i.e. the custom styles aren't being rendered)
• canned queries (i.e. the canned queries aren't being listed w/ the database)

As a test, we published the same database with Datasette stable (0.64.6) using the old format of metadata.yaml file (i.e. contains extra_css_urls and canned queries) and the custom styling and canned queries work as expected. From what I understand, we should be able to use the same metadata.yaml file with version 1.0a13. However, when we tested deploying Datasette latest using the same metadata.yaml file (using the old format), the custom CSS and canned queries did not work but everything else was working fine. We used the same parameters for datasette publish in both cases with the only difference being one used 0.64.6 while the other used 1.0a13.

I wanted to ask if there are any workarounds or solutions that would allow me to specify the aforementioned options (extra_css_urls, canned queries) during the deployment of 1.0a13 using datasette publish (similar to --extra-options perhaps?). Maybe I missed something in the documentation. Or do you think we'd need to deploy datasette manually for this to work?

Lastly, although using the stable version works as intended, we plan to use the 1.0 version because we want to include the datasette-write-ui plugin (w/c requires v 1.0a3) in the deployment. As such, we're also interested to know the status of datasette publish's support for using the datasette.yaml file.

Any help or pointers would be much appreciated.

Thanks!

Hi Simon,

Just an update: we managed to overcome the limitations mentioned above by deploying datasette 1.0a13 on a dedicated VPS (there were other requirements that Cloud Run wasn't able to address such as having mutable databases and using the upload-csvs plugin) but we're still very much interested in seeing and maybe even helping datasette publish eventually support settings in datasette.yaml
