810397025 MDU6SXNzdWU4MTAzOTcwMjU= 1228 500 error caused by faceting if a column called `n` exists Kabouik 7107523 closed 0     5 2021-02-17T17:41:20Z 2022-03-19T06:44:40Z 2022-03-19T01:38:04Z NONE  

I recently discovered datasette thanks to your great talk at FOSDEM and would like to use it for some projects. However, when trying to use it on databases created from some csv ot tsv files, I am sometimes getting this issue when going to http://127.0.0.1:8001/databasetest/databasetest and I don't exactly understand what it refers to.

So far, I couldn't find anything relevant when reviewing the raw text files that could explain this issue, nor could I find something obvious between the files that generate this issue and those that don't. Does the error ring a bell and, if so, could you please point me to the right direction?

Note that there is no error if I go to http://127.0.0.1:8001/databasetest and then click on Run SQL.

Facets are a tremendously useful feature, especially for people peeking at the database for the first time and still having little knowledge about the details of the data. It is of great assistance to discover interesting features to explore futher in advanced queries.

Yet, it seems it's impossible to use facets when running a custom SQL query, be it from the little gear icons in column names, the facet suggestions at the top (hidden when performing a custom query), or by appending a facet code to the URL.

Is there a technical limitation, or is this something that could be unlocked easily?
