1605959201,I_kwDOBm6k_c5fuP4h,2032,datasette errors when foreign key integrity is enabled,193185,open,0,,,0,2023-03-02T01:27:51Z,2023-03-02T01:31:58Z,,CONTRIBUTOR,,"By default, [SQLite does not enforce foreign key constraints](https://www.sqlite.org/foreignkeys.html#fk_enable). I typically enable these checks by running:

```sql
PRAGMA foreign_keys = ON;
```

inside of a `prepare_connection` hook.

If a plugin causes the schema to change (eg datasette-scraper creating a new table, or datasette-edit-schema changing a column), then https://github.com/simonw/datasette/blob/0b4a28691468b5c758df74fa1d72a823813c96bf/datasette/utils/internal_db.py#L71-L77 will fail with:

```
FOREIGN KEY constraint failed
```

This could be resolved by either:
- deleting from the `tables` column last
- changing the schema so that the foreign keys have [ON DELETE CASCADE](https://www.sqlite.org/foreignkeys.html#fk_actions)

Let me know if you'd be open to a PR that addresses this -- since foreign key constraints aren't enabled by default, I guess it's questionable whether this is a bug. I think I can workaround this by inspecting the database parameter in `prepare_connection` and trying not to enable fkey checks on the `_internal` database.",107914493,issue,,,"{""url"": ""https://api.github.com/repos/simonw/datasette/issues/2032/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,
