I don't think there is any reason for this limitation, as an FK allows joining in both directions.

This is an admittedly hacky change to implement bidirectional joins using `_through`. It does work for our use-case, but I don't know if there are other implications that I haven't thought of. Also if this change is desirable we probably want to make the code a little nicer.",107914493,pull,,,"{""url"": ""https://api.github.com/repos/simonw/datasette/issues/1475/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",0,
870946764,MDU6SXNzdWU4NzA5NDY3NjQ=,1312,how to query many-to-many relationship via json API?,5268174,open,0,,,0,2021-04-29T12:09:49Z,2021-04-29T12:09:49Z,,NONE,,"Hi,

Firstly thanks for Datasette, it's great!

I'm trying to use the JSON API to query data from a Datasette instance. I have a simple 3 table many-to-many relationship, like so:

`category` - list of categories
`document` - list of documents
`document_category` - join table (a category contains many documents, and a document can be a member of multiple categories)

the `document_category` table foreign keys to the other two using their respective row_ids.

Now I want to return ""all documents within category X"" but I cannot see a way to do this without executing two queries; the first to lookup the row_id of category X, and the second to join `document` with `document_category` where category ID is <id>.

I could easily write this in SQL, but this makes programmatic handling of pagination much more difficult (we'd have to dynamically modify the SQL to select the row_id and include the correct where and limit clauses).

Is there a way to achieve this using the JSON API?
