That's because the p that you're sending to your view is a QuerySet, not an object instance. Try the following:

{% for p_object in p %}
<tr>
    <td width="20%" class="scratchblackfont12">Release Name :</td>
    <td><div style="overflow:auto"><input name="Release Name (if any ):" autocomplete="on" type="text" class="scratchsearchfield" elname="defaultFocus" id="r1" value="{{p_object.version}}"  READONLY multiline="true" ></div>
    </td>
</tr>
{% endfor %}

If you'd like to send a specific p object instance you'd have to do the following in your view:

p = Discussion.objects.get(version=m2)

but note that get will throw an error if the query returns more than a single object with version=m2.

In your view, you've referenced Discussion1, which isn't the name of your model (Discussion). It's also not obvious where the value of m2 gets assigned.

I would verify that:

objects = Discussion.objects.filter(version=m2)

returns objects from the shell. At the minimum, you'll get an empty list.

It helps us out a lot if you format your code properly, in addition to providing enough context so we can tell where things come from, what's what and so on, in order to provide answer.
