Searching by "SearchableText" is broken #1151

Closed frapell closed 3 years ago

frapell commented 3 years ago

I've been trying to figure out how to fix this, and I can't quite make it... Searching by an attribute, like the title, works just fine

$ curl -i -X GET "http://127.0.0.1:8080/db/guillotina/@search?title__in=News" --user root:root

However searching by SearchableText fails

I believe this is related to this PR https://github.com/plone/guillotina/pull/1132 however trying guillotina from before that change also fails, but with a different Traceback

    sql, values, select, field = result
ValueError: not enough values to unpack (expected 4, got 3)

If I place a breakpoint in https://github.com/plone/guillotina/blob/master/guillotina/contrib/catalog/pg/parser.py#L50 I see

(Pdb) field,value
('title__in', 'News')

When searching using the title, however, when trying with SearchableText I see

(Pdb) field,value
('searchabletext__or', {'title__in': 'News'})

When using https://github.com/plone/guillotina-volto this looks like this

(Pdb) field,value
('searchabletext__or', {'text__in': 'News', 'title__in': 'News', 'url__in': 'News'})

And value being a dict happens in https://github.com/plone/guillotina/blob/master/guillotina/catalog/parser.py#L25

As you might have guessed, I am trying to fix the Search when using Volto + guillotina-volto, which uses SearchableText.

Any advice on where to fix this? I believe improving the process_compound_field method should be the way to go, what do you think? https://github.com/plone/guillotina/blob/fb562308fb62e991560a8e6527353664ae3070ac/guillotina/contrib/catalog/pg/parser.py#L30-L44

In trying to understand the changes of PR #1132 I don't think that's how the __or is intended to be used? According to the test, it seems the query is expected to be /db/guillotina/@search?__or=title%3DFirst item%26title%3DSecond item However, I think it should be /db/guillotina/@search?title__or=First item,Second item @bloodbare what do you think?

I think this is the right place. Can you try if changing the L31-33 with this code solves the problem?

if isinstance(value, dict):
    parsed_value = value.items()
else:
    parsed_value = urllib.parse.parse_qsl(urllib.parse.unquote(value))
    if not isinstance(parsed_value, list):
        return None

@masipcat Yup, that works like a charm!

Nice :) do you want to open a PR with this changes and if you don't mind, add a test for this case?

frapell commented 3 years ago

@masipcat Sure... How can I test against postgres? should I edit the TESTING_SETTINGS manually?

masipcat commented 3 years ago

Just set the env var DATABAES=postgres:

$ DATABASE=postgres pytest guillotina/tests
masipcat commented 3 years ago

you need to have docker installed and running. A pytest fixture will create the postgres container automatically
