Description

When using Django Formset, the error messaging isn't checking for the condition where both min_num and max_num are equal and both validate_min and validate_max are set to true.

Code highlighting: 

class TestForm(forms.Form):
    msg = forms.CharField()

test_formset = formset_factory(
  TestForm, 
  min_num=2, 
  max_num=2, 
  validate_min=True, 
  validate_max=True)

When formset is created in the following way and both validate flags are set True the following error messages show up

  • If the supplied forms are less than two - please submit 2 or more forms expected please submit 2 forms similarly the reverse is also true when the forms are more than two it gives the error message saying please submit 2 or fewer forms expected please submit 2 forms

This was a ​ bug reported on Wagtail and after investigating a little I noticed the incorrect messaging was coming from ​ this part in the validation

Thanks for this ticket. I would change the current messages instead of introducing a new one, e.g.

  • too_many_forms: "Please submit at most %d forms."
  • too_few_forms: "Please submit at least %d forms."

this would be consistent with the current behavior of other min/max validators.
