Just a short note on the snippet that was included in this thread: <blockquote> Take a look at this snippet: <a href="http://www.djangosnippets.org/snippets/1303/" rel="noreferrer">http://www.djangosnippets.org/snippets/1303/</a> </blockquote> It was very usefull, however it's including a few minor mistakes. More robust code should look like this: <pre><code># Add to your settings file CONTENT_TYPES = ['image', 'video'] # 2.5MB - 2621440 # 5MB - 5242880 # 10MB - 10485760 # 20MB - 20971520 # 50MB - 5242880 # 100MB - 104857600 # 250MB - 214958080 # 500MB - 429916160 MAX_UPLOAD_SIZE = "5242880" #Add to a form containing a FileField and change the field names accordingly. from django.template.defaultfilters import filesizeformat from django.utils.translation import ugettext_lazy as _ from django.conf import settings def clean_content(self): if content != None: content = self.cleaned_data['content'] content_type = content.content_type.split('/')[0] if content_type in settings.CONTENT_TYPES: if content._size > int(settings.MAX_UPLOAD_SIZE): raise forms.ValidationError(_(u'Please keep filesize under %s. Current filesize %s') % (filesizeformat(settings.MAX_UPLOAD_SIZE), filesizeformat(content._size))) else: raise forms.ValidationError(_(u'File type is not supported')) return content </code></pre> There are just a few improvements: First of all I'm detecting if the file field is empty (None) - without it, Django will cast an exception in web browser. Next is type casting in int(settings.MAX_UPLOAD_SIZE), because that setting value is a string. Strings cannot be used for comparing with numbers. Last but not least, the unicode 'u' prefix in ValidationError function. Thank you very much for this snippet!

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.
