(This is a ticket that Akismet wouldn't allow.)
When I use the wrong filter keyword (for example, a typo in a field
name), the error message says,
TypeError: Cannot resolve keyword 'storyitems' into field
Much nicer would be to show the list of field name that can be used:
TypeError: Cannot resolve keyword 'storyitem' into field, choices are:
tags, event, admintag, storycomment, favorite, story, storyundo,
feature, textblock, textblock, shareablelink, groupstory, textblock,
storyace, invitation, storyview, page, postcard, poster, id, name, date,
modified_date, template, template2, access, status, user,
caption_policy, share_policy, aspect, layout, flowmode, collmode,
widget, widgetstale, revision, undostate, karma, storydesign, type,
label, parent, product_id
This helps me get my code working faster, with less head-scratching.
Attached is the patch to query.py that enables these better messages.
