| 322787470 | MDU6SXNzdWUzMjI3ODc0NzA= | 259 | inspect() should detect many-to-many relationships | 9599 | closed | 0 | 6 | 2018-05-14T12:03:58Z | 2019-05-23T03:55:37Z | 2019-05-23T03:55:37Z | OWNER | Relates to #255 - in particular supporting facets across M2M relationships. It should be possible for `.inspect()` to notice when a table has two foreign keys to two different tables, and assume that this means there is a M2M relationship between those tables. When rendering a table with a m2m relationship we could display the first X associated records as a comma separated list of hyperlinks in a new column on the table view, with a column name derived from the table on the other side. Since SQLite doesn't have RANK or an equivalent of https://www.xaprb.com/blog/2006/12/02/how-to-number-rows-in-mysql/ this would be implemented as N+1 queries (one query per cell that we want to display an m2m summary). This should be OK in SQLite: https://sqlite.org/np1queryprob.html | 107914493 | issue | {"url": "https://api.github.com/repos/simonw/datasette/issues/259/reactions", "total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0} | completed |
