    <p>ModelMultipleChoiceField doesn't select initial choices and I can't make the following fix (link below) work in my example:</p> <p><a href="http://code.djangoproject.com/ticket/5247#comment:6" rel="noreferrer">http://code.djangoproject.com/ticket/5247#comment:6</a></p> <p>My models and form:</p> <pre><code>class Company(models.Model): company_name = models.CharField(max_length=200) class Contact(models.Model): company = models.ForeignKey(Company) first_name = models.CharField(max_length=100) last_name = models.CharField(max_length=100) class Action(models.Model): company = models.ForeignKey(Company, blank=True, null=True) from_company = models.ManyToManyField(Contact, verbose_name='Participant(s) from "Company"', blank=True, null=True) class Action_Form(ModelForm): from_company = forms.ModelMultipleChoiceField(queryset=Contact.objects.none(), widget=forms.CheckboxSelectMultiple()) class Meta: model = Action </code></pre> <p>What I do and the results:</p> <pre> >>> contacts_from_company = Contact.objects.filter(company__exact=1) # "1" for test, otherwise a variable >>> form = Action_Form(initial={'from_company': [o.pk for o in contacts_from_company]}) # as suggested in the fix >>> print form['from_company'] &lt;ul&gt; &lt;/ul&gt; >>> print contacts_from_company [&lt;Contact: test person&gt;, &lt;Contact: another person&gt;] >>> form2 = Action_Form(initial={'from_company': contacts_from_company}) >>> print form2['from_company'] &lt;ul&gt; &lt;/ul&gt; >>> form3 = Action_Form(initial={'from_company': Contact.objects.all()}) >>> print form3['from_company'] &lt;ul&gt; &lt;/ul&gt; </pre> <p>The way I was hoping it would work:<br> 1. My view gets "company" from request.GET<br> 2. It then filters all "contacts" for that "company"<br> 3. Finally, it creates a form and passes those "contacts" as "initial={...}" </p> <p><strong>Two questions:</strong><br> <strong>1. [not answered yet]</strong> How can I make ModelMultipleChoiceField take those "initial" values?<br> <strong>2. [answered]</strong> As an alternative, can I pass a variable to Action_Form(ModelForm) so that in my ModelForm I could have:</p> <pre> from_company = forms.ModelMultipleChoiceField(queryset=Contact.objects.filter(company__exact=some_id) # where some_id comes from a view </pre>

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.
