Question

The title pretty much sums it up – I have this tag in a template:

<a href="{% url mainapp.views.send_registration_email_view user_email=for_user.email,company_number=company.pk,organisation='org' %}">

with this in urls.py:

(r'^send/registrationlink/(?P<user_email>[^/]+)/(?P<company_number>[^/]+)/(?P<organisation>\w+)/?$', 'mainapp.views.send_registration_email_view'),

and this in mainapp/views.py:

def send_registration_email_view(request, user_email = None, company_number = None, organisation = None):

However, attempting to view a page which imports the template in which the problematic line is found, leads to this error:

TemplateSyntaxError: Caught NoReverseMatch while rendering: Reverse for 'mainapp.views.send_registration_email_view' with arguments '()' and keyword arguments '{'organisation': u'org', 'company_number': u'UN58e2391e-51a5-11e1-bb6a-e89a8f7f9c14', 'user_email': ''}' not found.

I also have these tags in the same template, and they work fine:

<a href="{% url mainapp.views.registration_view for_user=for_user %}">
<a href="{% url mainapp.views.consent_view for_user=for_user %}">

So – does anyone know why django doesn’t like what I’m doing?

Answer 1

This part of the regex: (?P<user_email>[^/]+) expects at least one character, but you’re passing an empty string as user_email. In a regex, + means ‘one or more’. Change it to * to also accept an empty string.
