    <p>I built an app using Django 1.3 and am now attempting to deploy to ubuntu 10.10 on linode using postgresql. I am using nginx on the front end and for static media and sending app requests to the app served with apache/mod_wsgi. Everything works fine on my local dev machine which is also Ubuntu 10.10 and I can install the app on my web server however when I try to access the home page I get the following error: 'str' object has no attribute '_default_manager'</p> <p>According to the error messages it appears that it is having trouble with a modelform where I subclassed a field, changing it from a FK field to a URLField and performing the validation manually. This is the form that throwing the error:</p> <pre><code>class TopicResourceForm(ModelForm): resource = URLField(label='Resource URL') class Meta: model = TopicResource fields = ('title', 'rtype', 'note') </code></pre> <p>And these are the models.</p> <pre><code>class TopicResource(models.Model): added = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) title = models.CharField(max_length=140, blank=True) note = models.TextField(blank=True) resource = models.ForeignKey('aresource.Resource') rtype = models.ForeignKey('aresource.ResourceType', verbose_name="Resource Type", blank=True, null=True) topic = models.ForeignKey('mystudy.Topic') def __unicode__(self): return '%s on %s' % (self.resource, self.topic) def get_absolute_url(self): return '/topics/%s/%s/%s' % (self.topic.slug, self.resource.id, self.id) class Resource(models.Model): added = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) url = models.URLField(unique=True) rtype = models.ForeignKey(ResourceType, verbose_name="Resource Type", blank=True, null=True) def __unicode__(self): return '%s' % self.url def get_absolute_url(self): return '/resources/%s' % self.id </code></pre> <p>Any help would be appreciated, thanks.</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.

SQuiL has stopped working due to an internal error.

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