Question

I think it may be a bug in modelformset_factory in Django 1.2, but I’d like anyone else to double check that (possibly in newer djnago versions as well).

Just for courious people – models are representing possible scores, and sets of those available for worker’s training reports.

models.py:

class ScoreSet(Model):
    unit = ForeignKey(Unit)
    description = CharField(max_length=20, verbose_name='description')

class Score(Model):
    scoreset = ForeignKey(ScoreSet)
    score = CharField(max_length=8, verbose_name='score')
    description = CharField(max_length=30, verbose_name='description')

and now:

FormSet = modelformset_factory(Score, exclude='scoreset', extra=5, can_delete=True)

will produce formset with no scoreset and no score field. If you change “scoreset” field name to anything else (eg. “ss”) it works fine, and excludes only “ss” field.

Answer 1

Exclude should be a tuple, not a string:

exclude=('scoreset',)
