please help.

You cannot assign variables in the template like that. Define "a" in the template context in a view. — stormlifter, Sep 23 '13 at 00:27

You are not writing valid django template code. You cannot use any python code in templates. You have to use specific django tags and filters. Have a read here: https://docs.djangoproject.com/en/1.5/topics/templates/

I your case, you should do this:

{% for i in mocument_objects %}
    <p>{{ i }}</p>    
{% endfor %}

You would need to pass monument_objects into your template context from the view.

you right, i did the same as it is in this post http://stackoverflow.com/questions/5871730/need-a-minimal-django-file-upload-example/8542030#8542030. its doing everything except its not printing the file names. even the BULLETS are printed but filename is missing/blank – ashir nasir Sep 23 '13 at 00:46
Did you override the `__unicode__` method on the `Mocument` model? – jproffitt Sep 23 '13 at 00:52
there are two class in model.py and i have added def __unicode__(self): return self.mocfile . is it ok? – ashir nasir Sep 23 '13 at 00:59
@ashirnasir maybe you are using `{% print i %}` instead of `{{ i }}`. That's probably why you are not getting the filenames. I suggest you read the django docs about [The Django template language](https://docs.djangoproject.com/en/1.4/ref/templates/api/). – juliomalegria Sep 23 '13 at 01:06
