Possible to send 2 querysets to response?

Question

Hi,
render_to_response Is it possible to pass more variables than just one? For example in my application I have a members model and then i would like to display the members information and also attendance information. Would I have to supply the arguments as a tuple?
Thanks in Advance,
Dean

Answer 1

Render_to_response accepts a context which is used for rendering. As far as I know there is no limitation on the number of variables you can pass in the context. This includes QuerySets. For example:

def my_view(request, *args, **kwargs):
    # ... etc ...
    q1 = Model1.objects.filter(**conditions)
    q2 = Model2.objects.filter(**conditions)
    context = dict(q1 = q1, q2 = q2)
    return render_to_response('my_template.html', context_instance = RequestContext(request, context))

My example uses RequestContext but it should be fine without it too.

# Template
{% for foo in q1 %} {{ foo }} {% endfor %}
... stuff ...
{% for bar in q2 %} {{ bar }} {% endfor %}

While Manoj is correct that you can pass variables by constructing your own context instance and passing it as a keyword argument to render_to_response, it's often shorter/simpler to use the second positional argument to render_to_response which accepts a dictionary that gets added to the context behind the scenes.

Take a quick look at the docs for render_to_response. Their example usage looks like this (and allows you to pass anything that can be stored in a dict to the renderer):

from django.shortcuts import render_to_response

def my_view(request):
    # View code here...
    return render_to_response('myapp/index.html', {"foo": "bar"},
        mimetype="application/xhtml+xml")
