This Field, Widget and the three lines of code in the form's clean method allow an easy (and hopefully general) way to add simple, unchangable text to a form.
Example use:
class OnlyTextForm(forms.ModelForm):
points = StaticField(label=_('Points'))
reviewer = StaticField(label=_('Reviewer'))
def clean(self):
for name, field in self.fields.items():
if isinstance(field, StaticField):
self.cleaned_data.update({name: self.initial[name]})
return self.cleaned_data
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 | class NoInput(forms.Widget):
def render(self, name, value, attrs=None):
return mark_safe(value)
class StaticField(forms.Field):
widget = NoInput
def clean(self, value):
return
