    <p>I am confused with contenttype in django. First let me show my codes:</p> <p>models.py</p> <pre><code>class Comment(models.Model): owner = models.CharField(max_length=255) email = models.EmailField(max_length=255) posted_at = models.DateTimeField(auto_now_add=True) content = models.TextField(blank=True, null=True) contentmarkdown = models.TextField(help_text='Use Markdown syntax.') content_type = models.ForeignKey(ContentType, limit_choices_to=models.Q( app_label='post', model='post') | models.Q(app_label='comment', model='comment')) object_id = models.PositiveIntegerField() content_object = generic.GenericForeignKey('content_type', 'object_id') def save(self, *args, **kwargs): import markdown self.content = markdown.markdown(self.contentmarkdown) super(Comment, self).save(*args, **kwargs) </code></pre> <p>my views.py</p> <pre><code>def create(request): if request.method == 'POST': print 'POST data: ', request.POST form = CommentForm(request.POST) #app_label, model = request.POST.get('model').split('.') if form.is_valid(): comment = Comment() content_type = ContentType.objects.get(app_label="comment", model="comment") object_id = ? comment = Comment.objects.create( content_type = content_type, object_id = object_id, contentmarkdown = request.POST.get('contentmarkdown'), owner= request.POST.get('owner'), email = request.POST.get('email') ) return HttpResponseRedirect("/") </code></pre> <p>urls.py</p> <pre><code>from django.conf.urls import patterns urlpatterns = patterns('', (r'^create/$', 'comment.views.create'), </code></pre> <p>html</p> <pre><code>{% load i18n %} &lt;div class="comment"&gt; &lt;form action="{% url "comment.views.create" %}" method="post"&gt; {% csrf_token %} {% for field in form %} {{ field.label_tag }} {{ field }}&lt;p&gt; {% endfor %} &lt;input type="submit" value="{% trans "Submit" %}"&gt; &lt;/form&gt; &lt;/div&gt; </code></pre> <p>forms.py</p> <pre><code>from django import forms from comment.models import Comment from django.forms import ModelForm class CommentForm(ModelForm): def __init__(self, *args, **kwargs): super(CommentForm, self).__init__(*args, **kwargs) self.fields['owner'].label = 'Name' self.fields['contentmarkdown'].label = '' class Meta: model = Comment exclude = ['content', 'content_type', 'object_id' ] </code></pre> <p>Now my question is that : I got this error: </p> <pre><code>object_id may not be NUL </code></pre> <p>1- How can I get object_id? 2- What am I supposed to write object_id = ? 3- There is nothing like id if I write this request.POST.get(?)

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).
