    <p>I am using the GAE Blobstore to upload and serve images for my Django app. For admin users maintenance is available by wrapping the image in a Django model <code>Image</code> and supplying the standard admin features for this model: add, update, delete.</p> <p>To perform the actual upload, I modified the <code>change_form.html</code> template for the Image model and replaced <code>{{ form_url }}</code> with <code>{{ blobstore_url}}</code>. <code>{{ blobstore_url }}</code> gets set by overriding the <code>render_change_form</code> of <code>ImageAdmin</code>.</p> <p>I noticed that by by calling <code>create_upload_url("/admin/some/url")</code>, I get an encoded url to GAE Blobstore's upload facility and the argument of the function ("/admin/some/url") is actually the url to which GAE/Blobstore redirects upon completion of the upload.</p> <p>Not really relevant to question, but something I noticed as well is that in my first approach I just overwrote the value of <code>{{ form_url }}</code> but that does not seem to work as the form's action was not set; it either gets overwritten somewhere else or is ignored.</p> <p>Although this works the main downside is that this approach requires me to implement "admin/some/url" as a view from where I can process the required add or change of the model Image, which really is duplication of code as the default admin already supports these features.</p> <p>So my question is what would be the correct url to pass to <code>create_upload_url()</code> in order to run the standard admin functionality of validation and database update for the Image model after completion of the upload?</p> <p><strong>EDIT</strong></p> <p>Alternatively, it might be a better design to perform the upload after the default admin operation (e.g. insert or update) have completed...</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.
