    <p>I'm trying to do this: in my web site, I have some data from database, like this:</p> <pre><code>Math 140 Math 141 CS 320 CS 240 </code></pre> <p>And I want to do it like this: When you check box and than press delete, this subject gets deleted from database.</p> <pre><code>Math 140 [] Math 141 [] CS 320 [] CS 240 [] </code></pre> <p>template.html</p> <pre><code> &lt;div id="subjects-list"&gt; {% if user.username %} &lt;ul&gt; {% if subjects %} {% for subject in subjects %} &lt;li&gt;{{ subject.name }} {% endfor %} {% else %} No Subjects for this user {% endif %} &lt;/ul&gt; {% else %} You are in else {% endif %} &lt;/div&gt; </code></pre> <p>models.py</p> <pre><code>class Subjects(models.Model): """ Subject Database """ name = models.CharField(max_length=64, unique=False) #Subject Names on left-menu user = models.ForeignKey(User, unique=False) def __unicode__(self): return '%s %s' %(self.name, self.user.username) </code></pre> <p>views.py</p> <pre><code>@login_required def user_page(request, username): user = get_object_or_404(User, username=username) ''' Form in the left-menu to create a new subject ''' if 'subject-create-b' in request.POST: subject_form = SubjectCreationForm(request.POST) if subject_form.is_valid(): subject = Subjects.objects.get_or_create(name = subject_form.data['name'], user = user) return HttpResponseRedirect('.') # redirect to the same page # later have to be substituted with AJAX else: subject_form = SubjectCreationForm() # Filter Subjects table by currently logged in user subjects = Subjects.objects.filter(user__exact = user) return render_to_response('user_page.html', {'subject_creation_form': subject_form, 'subjects': subjects, 'user': request.user, }, context_instance=RequestContext(request)) </code></pre> <p>So my question is basically how can I do this?</p> <p>Do I need to add new form and than put it right after the "<li>{{ subject.name }}". If yes, how do I know that this particular box have to delete this particular data object?</p> <p>Or do I need to add some new column to mymodels, and than if check box is checked - switch this column to true and than in views delete all rows that have true in new column.</p> <p>Or may be you can suggest some better techique. Thank you in advance!</p>

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.
