#4130 closed (fixed)

When mistyping a field name in an ORM call, the error message could be a lot more helpful.

Description

If I make a mistake when creating a filter call, the error message simply says, "Cannot resolve keyword 'pollls' into field".

More helpful is to show what the possible fields are: "Cannot resolve keyword 'pollls' into field, choices are: polls, cats, dogs"

Attached is a patch that changes the message in this way.

anonymous: Please don't change titles to include the word [patch]. It wastes space. We have a checkbox for that purpose (indicating patches, not wasting space).

Needs tests: set

FYI there are a couple of tests in tests/modeltests/lookup/models.py that test for this error message. They will need to be changed if the error message changes.

(In [5133]) Fixed #4130 -- Added more self-explanatory error message when a typo is made in
a queryset field argument.

We may need to fine-tune the error message based on experience down the line,
but this stands as an improvement on its own. Thanks, Ned Batchelder.
