django template does not render complete context

Question

Hello,

I am using templates with django. I am having a problem where the Context is not being rendered. The meta_k is null. The meta_description is not.

 t = get_template('projects.html')   
 html = t.render(Context({
       'completed': completed, 
       'current':current, 
       'description': sp.description, 
       'project_title':sp.name, 
       'img':images, 
       'meta_desc': sp.meta_description, 
       'meta_k:': sp.meta_keywords
 }))

I can start the server in debug mode in eclipse and So I know sp.meta_keywords is not null. Here is where I call the code in projects.html:

{% block meta_keywords %}<br>
{% if meta_k %}<br>
&nbsp;&nbsp;&nbsp;&nbsp;{{ meta_k }}<br>
{% else %}<br>
&nbsp;&nbsp;&nbsp;&nbsp;Venkat, Rao, engineer, inventor, entrepreneur, projects, blue dart, control systems, labview<br>
{% endif %}<br>
{% endblock %}

This defaults to the else when I know meta_k should not be null. The complete code can be found here on Google Code.

What am I doing wrong?

Only suggestion for you is that most probably it is bug in your code, for us it will be difficult to debug without running your whole project.

So i suggest you experiment on command line and see if you can replicate the bug in simple steps, so that we can try to fix it. I am sure in the process you will find the problematic part

e.g. I see your template rendered correctly by my simple context

>>> from django.template import Context, Template
>>> s = """{% block meta_keywords %}<br>
... {% if meta_k %}<br>
... &nbsp;&nbsp;&nbsp;&nbsp;{{ meta_k }}<br>
... {% else %}<br>
... &nbsp;&nbsp;&nbsp;&nbsp;Venkat, Rao, engineer, inventor, entrepreneur, projects, blue dart, control systems, labview<br>
... {% endif %}<br>
... {% endblock %}"""
>>> t = Template(s)
>>> c = Context({'meta_k':['a','b','c']})
>>> t.render(c)
u'<br>\n<br>\n&nbsp;&nbsp;&nbsp;&nbsp;[&#39;a&#39;, &#39;b&#39;, &#39;c&#39;]<br>\n<br>\n'

So I was just making stupid mistake:

in the rendering file i have: html = t.render(Context({'completed': completed, 'current':current, 'description': sp.description, 'project_title':sp.name, 'img':images, 'meta_desc': sp.meta_description, 'meta_k:': sp.meta_keywords) this refers to "meta_k:" note the semicolon

in the template I have {% if meta_k %} note no semicolon

if i remove the semicolon it works. that was stupid.
