    <p>Currently, the default Django FileField upload method with the application we host on app engine using Google Cloud SQL returns the following error:</p> <pre><code>OSError [Errno 38] Function not implemented: '/base/data/home/apps/s~app/attachment-1.360717349796013945/media' </code></pre> <p>which is probably due to file writing being restricted in app engine and mkdir not working stated in Django debug mode:</p> <pre><code>/base/python27_runtime/python27_dist/lib/python2.7/os.py in makedirs makedirs(head, mode) except OSError, e: # be happy if someone already created the path if e.errno != errno.EEXIST: raise if tail == curdir: # xxx/newdir/. exists if xxx/newdir exists return mkdir(name, mode) ... </code></pre> <p>Therefore, I attempted to install <a href="http://www.allbuttonspressed.com/projects/django-filetransfers" rel="nofollow">django-filetransfer</a> and the same error persists on Appengine. </p> <p>Django setup:</p> <p><strong>Models</strong></p> <pre><code>class OrderItemAttachmentForm(ModelForm): class Meta: model = OrderItemAttachment exclude = ('item',) def __init__(self, *args, **kwargs): super(OrderItemAttachmentForm, self).__init__(*args, **kwargs) </code></pre> <p><strong>Views</strong></p> <pre><code>def RFO(request): view_url = reverse('app.views.RFO') elif 'saveLine' in request.POST: order_attachment_form = OrderItemAttachmentForm(request.POST,request.FILES) if order_attachment_form.is_valid(): order_attachment = order_attachment_form.save() upload_url, upload_data = prepare_upload(request, view_url) </code></pre> <p><strong>Template</strong></p> <pre><code>{% load filetransfers %} &lt;form id="requestItemForm" name="requestItemSubmit" method="post" enctype="multipart/form-data" action="{{ upload_url }}"&gt;{% csrf_token %}{% render_upload_data upload_data %} &lt;div class="lineAttach"&gt; &lt;label for="id_attachment"&gt;Upload Attachment&lt;/label&gt; {{order_attachment_form.attachment}} &lt;/div&gt; &lt;button type="submit" id="saveLine" name="saveLine" class="btn grey doLoad right" value="Save Line Item"&gt;Save Line Item&lt;/button&gt; </code></pre> <p>I have contemplated using <a href="https://developers.google.com/appengine/docs/python/blobstore/" rel="nofollow">Blobstore python API</a> to store files as a blob or utilize Google Cloud Storage but do not know how to integrate it into Django models. 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.

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