I have the following form code:
# forms.py class SomeForm(forms.Form): hello = forms.CharField(max_length=40) world = forms.CharField(max_length=40) def clean(self): raise forms.ValidationError('Something went wrong') # views.py def some_view(request): if request.method == 'POST': form = SomeForm(request.POST) if form.is_valid(): pass else: form = SomeForm() data = { 'form': form } return render_to_response( 'someform.html', data, context_instance=RequestContext(request) ) # someform.html {{ form.hello }} {{ form.hello.errors }} {{ form.world }} {{ form.world.errors }} How can I display the errors from the key __all__ at the template level without having to extract it in the view separately? I want to avoid the following:
if form.errors.has_key('__all__'): print form.errors['__all__']

The error_messages argument lets you override the default messages that the field will raise. Pass in a dictionary with keys matching the error messages you want to override. For example, here is the default error message: >>> from django import forms >>> generic = forms.
To display the form errors, you use form. is_valid() to make sure that it passes validation. Django says the following for custom validations: Note that any errors raised by your Form.
The run_validators() method on a Field runs all of the field's validators and aggregates all the errors into a single ValidationError . You shouldn't need to override this method.
