.json extension to get JSON of a dashboard

[simonw]

Simple feature: /dashboard/name.json gives you a JSON version of that saved dashboard data, if you have permission to view the page.

Got a prototype working that looks like this:

{
  "title": "Tag word cloud",
  "queries": [
    {
      "sql": "select \"tag\" as wordcloud_word, count(*) as wordcloud_count from (select blog_tag.tag from blog_entry_tags join blog_tag on blog_entry_tags.tag_id = blog_tag.id\r\nunion all\r\nselect blog_tag.tag from blog_blogmark_tags join blog_tag on blog_blogmark_tags.tag_id = blog_tag.id\r\nunion all\r\nselect blog_tag.tag from blog_quotation_tags join blog_tag on blog_quotation_tags.tag_id = blog_tag.id) as results where tag != 'quora' group by \"tag\" order by wordcloud_count desc",
      "rows": [
        {
          "wordcloud_word": "python",
          "wordcloud_count": 826
        },
        {
          "wordcloud_word": "javascript",
          "wordcloud_count": 604
        },
        {
          "wordcloud_word": "django",
          "wordcloud_count": 529
        },
        {
          "wordcloud_word": "security",
          "wordcloud_count": 402
        },
        {
          "wordcloud_word": "datasette",
          "wordcloud_count": 331
        },
        {
          "wordcloud_word": "projects",
          "wordcloud_count": 282
        }

This will be on by default but I'll provide a setting for turning it off.

I can't figure out how to run the tests locally. I tried this but it didn't work:

[simonw]

All tests are broken in CI too: https://github.com/simonw/django-sql-dashboard/actions/runs/7230325348/job/19702260457

I think it's a pytest version issue.

[simonw]

It's this problem here:

• Upgrade to pytest-django 4.3.0 #109

Pinning to pytest-django==4.2.0 still fixes it.

[simonw]

Managed to run tests locally with:

PYTHONPATH=pytest_plugins:test_project \
POSTGRESQL_PATH=/Applications/Postgres.app/Contents/Versions/15/bin/postgres \
DJANGO_SETTINGS_MODULE=config.settings_interactive \
INITDB_PATH=/Applications/Postgres.app/Contents/Versions/15/bin/initdb \
python -m pytest --lf -x --pdb

[simonw]

Error:

E django.db.utils.NotSupportedError: PostgreSQL 12 or later is required (found 10.23).

I'll drop older PostgreSQL.
