Model Method with a Variable

Question

I have the following view that takes the value of "q" from a template:

from django.http import HttpResponse
from django.shortcuts import render_to_response
from GOTHAMWEB.GRID.models import *

def search(request):
    errors = []
    if 'q' in request.GET:
        q = request.GET['q']
        if not q:
            errors.append('Enter a search term.')
        elif len(q) > 20:
            errors.append('Please enter at most 20 characters.')
        else:
            srvr = Server.objects.filter(name__icontains=q)
        return render_to_response('search_results.html',
                {'srvr': srvr, 'query': q})

    return render_to_response('search_form.html',
        {'errors': errors})

Is it possible to pass the value of q from the view to a model method, such as "server='q' " below. I have tried this but is fails. Before concluding it cannot be done, will someone please tell me for certain.

class MemoryManager(models.Manager): 
    def get_query_set(self): 
        return super(MemoryManager, self).get_query_set().filter(server='q')

Answer 1

It's not at all clear what you are trying to do here. In the function, you are filtering on the value of the GET variable q. But in the Manager, you are filtering on the string "q".

Did you just want to pass the value of q into the Manager? If so, the easiest way would be to define a separate Manager method:

class MemoryManager(models.Manager):
    def filter_server(q):
        return self.get_query_set().filter(server=q)

Now you can call Server.memsinserver.filter_server(q). Is that what you wanted?
