Django: List of valid field lookup operators

Question

Does Django have an accessible list of all valid field lookup operators (those that are used by the QuerySet API, e.g. 'contains', 'in', 'lt', etc)?

Thanks

EDIT: For clarification, I mean an in-code list that I can import so, for example, I can check if a given string matches a valid operator.

Answer 1

After searching the source for the operators, it lives in django.db.models.sql.constants.QUERY_TERMS.

A dictionary with lookup strings mapped to None.

'exact' in QUERY_TERMS

Thanks for this! Never would have gone looking, but I could definitely use this.

Answer 2

As of Django 2.1, django.db.models.sql.constants.QUERY_TERMS constant is removed. Per the release notes, Django recommends the get_lookups() method of the Lookup Registration API as an alternative.

For a given field on a model, it can be accessed via:

MyModel._meta.get_field('my_field').get_lookups()
