    <p>My questions are: How did you define your models? Can you get the users from the group? Can you get the groups from the user? something like that:</p> <pre><code>groups = Group.objects.get(pk=1) groups.users user = User.objects.get(pk=1) user.groups </code></pre> <p>You can do that writing this in you code:</p> <pre><code>#models.py class User(Model): name = CharField(max_length=200) class Group(Model): name = CharField(max_length=200) users = ManyToManyField(User, related_name="groups") #forms.py class ArrangeUserForm(forms.Form): def __init__(self, *args, **kwargs): super(ArrangeUserForm, self).__init__(*args, **kwargs) groups = groups.objects.filter(name="sale") user_choices = User.objects.filter(groups_in=groups) self.fields['user_field'] = forms.ChoiceField(widget=forms.Select, choices=user_choices) mobile = forms.CharField(widget=forms.TextInput, max_length=11, min_length=11) #And you views.py class ArrangeUserHandler(FormView): form_class = ArrangeUserForm template_name = 'student/student_form.html' def form_valid(self, form): #When the form is valid return super(ArrangeUserHandler, self).form_valid(form) def form_invalid(self, form): #When the form is invalid return super(ArrangeUserHandler, self).form_invalid(form) </code></pre> <p>I think that It should work fine and quickly. Will you tell me if this lines work?</p> <pre><code># ... groups = groups.objects.filter(name="sale") user_choices = User.objects.filter(groups_in=groups) # ... </code></pre> <p>I hope that helps. see the Documentation of <a href="https://docs.djangoproject.com/en/dev/topics/db/examples/many_to_many/" rel="nofollow"> ManyToMany field</a> and <a href="https://docs.djangoproject.com/en/1.5/ref/class-based-views/generic-editing/" rel="nofollow">FormView </a> if you are in django 1.5</p>

    2. CONo problem, but consider re write your queries, yo are making `User.objects.all()` and `user.groups.filter(name="sale")` for every user in db. You are getting all user objects, then making foreach and making queries by everyone. I'm making 2 queries `groups.objects.filter(name="sale")` and `User.objects.filter(groups_in=groups)`. This is quickly and readable. See you!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
