After reading over the newforms documentation, I came across the Form.clean() method that suites my case nicely regarding my newforms- admin form:
""" The Form subclass’s clean() method. This method can perform any validation that requires access to multiple fields from the form at once. This is where you might put in things to check that if field A is supplied, field B must contain a valid email address and the like. The data that this method returns is the final cleaned_data attribute for the form, so don’t forget to return the full list of cleaned data if you override this method (by default, Form.clean() just returns self.cleaned_data). Note that any errors raised by your Form.clean() override will not be associated with any field in particular. They go into a special “field” (called __all__), which you can access via the non_field_errors() method if you need to. """ My validation across multiple form fields works now, however I can not get an error message to be displayed on the page. The last paragraph indicates that error(s) raised will not be associated with any particular field(s). Can someone please explain the last sentence in the above doc snippet with regards to the special 'field' called __all__? regards, -al On Apr 30, 5:50 pm, "[EMAIL PROTECTED]" <[EMAIL PROTECTED]> wrote: > Hi Al, > > On Apr 30, 2:18 pm, "[EMAIL PROTECTED]" <[EMAIL PROTECTED]> > wrote: > > > > > I would like to add some custom validation to the newform-admin form. > > I have look at the > > -http://code.djangoproject.com/wiki/NewformsHOWTO#Q:HowdoIaddcustomval... > > - and am still not finding a solution. > > > Here is what I'm trying to do: > > > I have several form fields on an admin form that correspond to a > > relevant model. > > I'd like to add custom validation to one of the char fields (choice > > box) called 'status'.
