Variables in the Django template

I would like to use the {% url %} tag in order to do something, and I encountered the following problem:

1. I pass a model containing pages

   {% for page in pages %}

2. I want to insert the page name in the parameter, but Django complains about this syntax

   {% url 'blog.views.view' page_name={{ page.name }} %}

   {% endfor %}

Please tell me what I am doing wrong
