Django Admin validation

Question

I'd like to validate user input with regular expression in Django Admin CharField... How is it possible?

Thanks in advance, Etam.

Answer 1

Define a custom form for your model admin, and override the specific field to use a RegexField.

class MyModel(models.Model):
    myfield = models.CharField(max_length=10)


class MyModelForm(forms.ModelForm):
    myfield = forms.RegexField(regex=r'\w+')


class MyModelAdmin(admin.ModelAdmin):
    form = MyModelForm

admin.site.register(MyModel, MyModelAdmin)
