    <p>I have a Django template which is displaying a file field like so:</p> <pre><code> &lt;div class="fieldWrapper"&gt; {{ auth_users_ext.user_pic.error }} Image Upload: {{ auth_users_ext.user_pic }} &lt;/div&gt; </code></pre> <p>I've used the necessary enctype="multipart/form-data". The field correctly displays a value being pulled from the database, so I have so far assumed that it is functioning as it's supposed to. The problem I'm having is that wherever I place the field within the template file, the request.POST data is truncated at that point.</p> <p>So, if I place the field last on the form, I get every field above it. If I place the field at the very top of the form, I get nothing at all.</p> <p>I can read the POST payload in Chrome and verify that the POST data being passed to the view is complete:</p> <pre><code>------WebKitFormBoundaryZTdhKmOKbDRAXLAm Content-Disposition: form-data; name="csrfmiddlewaretoken" ******** ------WebKitFormBoundaryZTdhKmOKbDRAXLAm Content-Disposition: form-data; name="csrfmiddlewaretoken" ******** ------WebKitFormBoundaryZTdhKmOKbDRAXLAm Content-Disposition: form-data; name="staff_id" 98.0 ------WebKitFormBoundaryZTdhKmOKbDRAXLAm Content-Disposition: form-data; name="auth_user_id" 1069 ------WebKitFormBoundaryZTdhKmOKbDRAXLAm Content-Disposition: form-data; name="user_groups" 1 ------WebKitFormBoundaryZTdhKmOKbDRAXLAm Content-Disposition: form-data; name="user_groups" 11 ------WebKitFormBoundaryZTdhKmOKbDRAXLAm Content-Disposition: form-data; name="user_groups" 13 ------WebKitFormBoundaryZTdhKmOKbDRAXLAm Content-Disposition: form-data; name="current_pic" /media/no_pic.jpg ------WebKitFormBoundaryZTdhKmOKbDRAXLAm Content-Disposition: form-data; name="user_pic"; filename="Picture0029.jpg" Content-Type: image/jpeg ------WebKitFormBoundaryZTdhKmOKbDRAXLAm Content-Disposition: form-data; name="first_name" Robert ------WebKitFormBoundaryZTdhKmOKbDRAXLAm Content-Disposition: form-data; name="last_name" Vila ------WebKitFormBoundaryZTdhKmOKbDRAXLAm Content-Disposition: form-data; name="username" bobvila ------WebKitFormBoundaryZTdhKmOKbDRAXLAm Content-Disposition: form-data; name="email" BobVila@thisoldhouse.com ------WebKitFormBoundaryZTdhKmOKbDRAXLAm Content-Disposition: form-data; name="work_number" 1239111234 ------WebKitFormBoundaryZTdhKmOKbDRAXLAm Content-Disposition: form-data; name="mobile_number" 1239111234 ------WebKitFormBoundaryZTdhKmOKbDRAXLAm Content-Disposition: form-data; name="mgr_id" 1 ------WebKitFormBoundaryZTdhKmOKbDRAXLAm-- </code></pre> <p>Regardless, when I specify request.FILES['user_pic'] in the view, I get nothing.</p> <p><strong>UPDATED</strong></p> <p>Here is the relevant code from the view:</p> <pre><code>def STAFF(request, uid=None, template='auth_user.html'): [ ... ] user = request.user is_admin = user.groups.filter(name='*** ADMIN_GROUP_NAME ***') if uid == None: instance = AuthUser() ext_instance = AuthUserExt() else: instance = AuthUser.objects.get(auth_user_id=uid) ext_instance = AuthUserExt.objects.get(auth_user_id=uid) if request.method == 'POST': # get image request.FILE object if request.FILES: avatar = request.FILES['user_pic'] # build destination path for os file handling dest_path = settings.MEDIA_ROOT + request.POST['username'] + '/avatar/' # create user/avatar dir if not exist if not os.path.exists(dest_path): os.makedirs(dest_path) # open file handle at the intended destination and write our request.FILE if os.path.isfile(dest_path + avatar.name): os.remove(dest_path + avatar.name) destination = open(dest_path + avatar.name, 'wb+') destination.write(avatar.read()) destination.close() # build uri path for database insert uri_path = settings.MEDIA_URL + request.POST['username'] + '/avatar/' + avatar.name else: [ ... ] # lands here, because Django produces no request.FILES </code></pre>

    3. CO@zubair89: there's no actual file processing going on in the model. the only server-side handling would be moving the uploaded file, but it's not getting that far because Django is failing in generating the `request.POST\FILES` data when it encounters this field. this code worked five months ago when it was first tested, but so many things about the environment have changed since then that i have no way of knowing what the issue might be. the logs give no indication that i can detect, simply showing a 500 error.

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).
