  1. POreturning additional context variables in Django
    text
    copied!<p>I have a page that users can search for other users on and once they search, a list of users is displayed that match their search criteria. Next to each user in the search results, I have a link to "Add as friend'. Each link is linked to a python function in the urls.py file that will add the request to the database etc. However, I am not using AJAX for this as of yet as I am trying to make everything that I can work with or without JavaScript. But once the python function is called, I want to return a context variable back to the template that called the function and add a variable so that I can check for it in the template and remove the link that the user clicked but leave all other links next to all other users. The python function is below:</p> <pre><code>def request_friend(request,to_friend): try: from_friend = request.user to_friend = CustomUser.objects.get(pk=to_friend) f = Friendship(from_friend=from_friend,to_friend=to_friend) f.save() f1 = Friendship(from_friend=to_friend,to_friend=from_friend) f1.save() try: text = "&lt;a href='/%s/'&gt;%s&lt;/a&gt; has requested you as a friend" % (from_friend.username,from_friend.username) n = Notification(from_user=from_friend,to_user=to_friend,notification_text=text) n.save() response = 'Friend Requested' except: response = 'Couldnt save notification' except: response = 'Did not save to database' return TemplateResponse(request,'users/friend_search.html',{'friend_added':response}) </code></pre> <p>And the template code that shows the list of users is below:</p> <pre><code>{% for u in users %} &lt;div id="results"&gt; &lt;img src="{{ u.profile_pic }}" class="xsmall-pic" /&gt; &lt;a href="/{{ u.username }}/"&gt;{{ u.username }}&lt;/a&gt;&lt;br /&gt; &lt;span class="small-date"&gt;{{ u.get_full_name }}&lt;/span&gt; &lt;span class="floatR" id="user_{{ u.id }}_link"&gt;{% if not friend_added %}&lt;a href="/users/requests/friends/{{ u.id }}/" id="{{ u.id }}" class="user_link" onclick="return request_friend({{ u.id }});"&gt;Add as friend&lt;/a&gt;{% else %}{{ friend_added }}{% endif %}&lt;/span&gt; &lt;/div&gt;{% endfor %} </code></pre> <p>How can I accomplish this? Thanks</p>

Larger individual text columns get their own page to allow for proper reading.
