Filters always take either one or two arguments but not more. See:
http://www.djangoproject.com/documentation/templates_python/#writing-custom-template-filters
Here's how you can pass in multiple parameters.
Change your filter function to take in just one real parameter that
multiplexes three comma-separated parameters:
def dynamicformfield(value, parts):
firstpart, midpart, lastpart = parts.split(',')
# you've got your three parameters now to run with
The filter usage would be:
{{ form.errors|dynamicformfield:"pass,1,firstname" }}
In other words, you specify all 3 parts as a single string with comma-
separated values that you can then demultiplex in your filter
function.
