| 795367402 | MDU6SXNzdWU3OTUzNjc0MDI= | 1209 | v0.54 500 error from sql query in custom template; code worked in v0.53; found a workaround | 11788561 | open | 0 | 1 | 2021-01-27T19:08:13Z | 2021-01-28T23:00:27Z | NONE | v0.54 500 error in sql query template; code worked in v0.53; found a workaround **schema:** CREATE TABLE "talks" ("talk" TEXT,"series" INTEGER, "talkdate" TEXT) CREATE TABLE "series" ("id" INTEGER PRIMARY KEY, "series" TEXT, talks_list TEXT default '', website TEXT default ''); **Live example of correctly rendered template in v.053:** https://cosmotalks-cy6xkkbezq-uw.a.run.app/cosmotalks/talks/1 **Description of problem:** I needed 'sql select' code in a custom row-mydatabase-mytable.html template to lookup the series name for a foreign key integer value in the talks table. So `metadata.json` specifies the `datasette-template-sql` plugin. The code below worked perfectly in v0.53 (just the relevant sql statement part is shown; full code is [here](https://github.com/jrdmb/cosmotalks-datasette/blob/main/templates/row-cosmotalks-talks.html)): ``` {# custom addition #} {% for row in display_rows %} ... {% set sname = sql("select series from series where id = ?", [row.series]) %} <strong>Series name: {{ sname[0].series }} ... {% endfor %} {# End of custom addition #} ``` **In v0.54, that code resulted in a 500 error with a 'no such table series' message.** A second query in that template also did not work but the above is fully illustrative of the problem. All templates were up-to-date along with datasette v0.54. **Workaround:** After fiddling around with trying different things, what worked was the syntax from [Querying a different database from the datasette-template-sql github repo](https://github.com/simonw/datasette-template-sql#querying-a-different-database) to add the database name to the sql statement: `{% set sname = sql("select series from series where id = ?", [row.series], database="cosmotalks") %}` Though this was found to work, it should not be necessary to add `database="cosmotalks"` since per the `datasette-template-sql` README, it's only needed when querying a different database, but here it's a table within the same database. | 107914493 | issue |
