How to get django form errors as text instead of html?

Question

I have a toast for displaying errors.

$.toast({
    text: '{{ form.non_field_errors }}'
})

But it is returning a html format. so i am getting an error.

But i would like to get text only from {{ form.non_field_errors }}. How do i do that?

You can use the .as_text() method, on the non_field_errors:

$.toast({
    text: '{{ form.non_field_errors.as_text }}'
})

Note however that in order to make this more safe, you better JSON-ify this, and furthermore mark the output as safe.

You thus better do some processing in the view:

from json import dumps as jdumps

def some_view(request):
    some_form = ModelForm(request.POST)
    errors = jdumps(some_form.non_field_errors().as_text())
    return render(request, 'some_template.html', {'errors': errors})

and in the template render this as:

$.toast({
    text: {{ errors|safe }}
})
