URL模板标记中的多个参数

Question

I'm trying to add a couple arguments to my url, if I have only a single argument everything works great. However, if I try to use 2 it converts them to a dict and throws an error. Below are a couple thing that I have tried without success, any help would be awesome. I'm running Django 1.8.4

            {% autoescape off %}
            <a href={% url "products.views.display_product_list" page=previous keyword=current_keyword %}>
                Previous</a>
            Current Page
            <a href={% url "products.views.display_product_list" page=next keyword=current_keyword %}>
                Next</a>
            {% endautoescape %}

            <a href={% url "products.views.display_product_list" page=previous,keyword=current_keyword %}>
                Previous</a>
            Current Page
            <a href={% url "products.views.display_product_list" page=next,keyword=current_keyword %}>
                Next</a>

The first gives an error of NoReverseMatch at /results/page-0/

While the second is TemplateSyntaxError at /results/page-0/ Could not parse the remainder

My URL looks like:

r'^(?:page-(?P<page>[0-9]*)/)(?:keyword-(?P<keyword>[0-9A-Z]*)/)?$'

Webpage Traceback:

Answer 1

(?P<keyword>[0-9A-Z]*)

This part of your regex only matches digits and uppercase letters, but you pass a lowercased word to the {% url %} tag. You need to change the pattern accordingly:

(?P<keyword>[0-9a-zA-Z]*)
