What if the query page spotted `?id=11&id=32&id=62` and turned that into a JSON string called `:id:` with a value of `["11", "32", "62"]`? Note that this is still a string, not a list. This avoids a nasty problem that occurred in PHP world, where `?id[]=1&id[]=2` would result in an actual PHP array object, which often broke underlying code that had expected `$_GET["id"]` to be a string, not an array. So in a query you'd be able to do this: where id in (select value from json_each(:id)) And then call it with `?id=11&id=32&id=62`. {"total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0} Potential feature: special support for `?a=1&a=2` on the query page 1615692818

Maybe with syntax like this: where id in (select value from json_each(:id__list)) Datasette would automatically pass `{"id": "11", "id__list": '["11", "32", "62"]'}` as arguments to the `db.execute()` method, if the page was called with `?id=11&id=32&id=62`. This is more explicit, though the syntax is a bit uglier (maybe there's a nicer design for this?). I also worry about `?id__list=` conflicting with this, but I think that's a risk I can take - tell people not to do that, or even block `?id__list=` style parameters entirely. {"total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0} Potential feature: special support for `?a=1&a=2` on the query page 1615692818

The main question I have is which of these options to implement: 1. `?id=1&?id=2` results in `:id` in the query being `["1", "2"]` - no additional syntax required 2. `:id` in the query continues to reference just the first of those parameters - but `:id__list` (or some other custom syntax) instead gets `["1", "2"]` - or, if the URL is `?id=1` - gets `["1"]` Actually on writing these out I realize that option 2 is the ONLY valid option. It's no good building a query that works against a JSON list if the user might pass just a single ID, `?id=1`, resulting in their query breaking. {"total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0} Potential feature: special support for `?a=1&a=2` on the query page 1615692818

Also, when a page is re-displayed for on of these queries it could potentially add an extra form field allowing people to add another value. Though this has an annoying problem: how to tell the difference between an additional `id` input field that the user chose not to populate, v.s. one that is supposed to represent an empty string?

It's documented here: https://docs.datasette.io/en/0.64.2/custom_templates.html#custom-templates > If you want to output the rendered HTML version of a column, including any links to foreign keys, you can use `{{ row.display("column_name") }}`. I can't see any examples of anyone using it in this code search: https://cs.github.com/?scopeName=All+repos&scope=&q=datasette+row.display It is however useful to have some kind of abstraction layer here that insulates the SQLite `Row` object, since having an extra layer will help if Datasette ever grows support for alternative database backends such as DuckDB or PostgreSQL. {"total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0} ?_extra= support (draft) 1551694938

A few options for doing that: - Introduce `?_extra=_html` where the leading underscore indicates that this is a "bundle" of extras, then define a bundle that's everything needed for the HTML renderer - Have some other mechanism whereby different renderers can request a bundle of extras.
