title: Django-Filter Form Displaying All Filters?
body: <p>I've just started working with Django Filter. When I test, the filter.form shows filters for all fields and I can't get it to show only the desired filters.</p>
  
  <p>Here's the filter:</p>
  
  <pre><code>class EmployeeFilter(django_filters.FilterSet):
      hire_date = django_filters.DateFilter(name='hireDate', lookup_expr='hireDate__year')
      hire_date__gte = django_filters.DateFilter(name='hireDate', lookup_expr='hireDate__gte')
      hire_date__lte = django_filters.DateFilter(name='hireDate', lookup_expr='hireDate__lte')   
  
      class Meta:
          model = models.Employee
          fields=['hireDate']
  </code></pre>
  
  <p>Here's the view:</p>
  
  <pre><code>def test_filters(request, template_name='filter-test.html'):
      from . import filters
  
      f = filters.EmployeeFilter(request.GET, queryset=models.Employee.objects.all()) 
  
      return render_to_response(template_name, locals(), context_instance=RequestContext(request))
  </code></pre>
  
  <p>Has anyone ever run into this? How'd you fix?</p>
