-------------------------------------+-------------------------------------
Encountered a limitation in Django ORM when using annotations with column
aliases containing special characters like apostrophes or spaces. For
example:
Model.objects.annotate(**{"VALUE_WITH_APOSTROPHE'-2":
Count('attribute_name')})
This generates a ValueError: Column aliases cannot contain whitespace
characters. While SQL syntax allows such aliases, Django ORM does not,
leading to a lack of flexibility and unexpected errors in ORM
interactions.
Impact:
- Causes flow errors during higher-level ORM interactions.
- Limits application of ORM to real-world naming use cases.
- Decreases reliability and user experience when special characters are
present.
Proposed Solution:
Enhance the ORM's handling of annotate aliases to allow common special
characters, aligning with real-world naming scenarios. Options could
include:
- Automatically transforming aliases before passing to SQL.
- Configurable rules for "safe" special characters at the ORM level.
Interested in community and maintainers' perspectives on potential
solutions to provide ORM-level flexibility for end-user applications.
Looking forward to contributing to the discussion and development of this
feature.
