    <p>I have a such problem - I am using Python 2.6 / Django 1.3 and I need to <strong>accept as POST variable with key 'f', which contains a binary data</strong>. After that, I need to <strong>save data</strong> in a file.</p> <p><strong>POST</strong></p> <pre><code>T$topX$objectsX$versionY$archiverО©ҐR$0О©ҐО©ҐО©Ґull_=&lt;---------------------- content of file --------------------&gt;О©ҐО©Ґ_NSKeyedArchive(258:=CО©ҐО©Ґ </code></pre> <p><strong>Code</strong></p> <pre><code>from django.core.files.storage import default_storage from django.core.files.base import ContentFile def save(request): upload_file = request.POST['f'] save_path = default_storage.save('%s%s' % (save_dir, filename), ContentFile(upload_file)) </code></pre> <p>When I am trying to do</p> <pre><code>nano /tmp/myfile.zip </code></pre> <p>It returns data like </p> <pre><code>T^@^@^@$^@^@^@t^@^@^@o^@^@^@p^@^@^@X^@^@^@$^@^@^@o^@^@^@b^@^@^@j^@^@^@e^@^@^@c^@^@^@t^@^@^@s^@^@^@X^@^@^@$^@^@^@v^@^@^@e^@^@^@r^@^@^@s^@^@^@i^@^@$ </code></pre> <p>When its done, I am going to <strong>read saved file</strong> </p> <pre><code>def read(request): user_file = default_storage.open(file_path).read() file_name = get_filename(file_path) response = HttpResponse(user_file, content_type = 'text/plain', mimetype = 'application/force-download') response['Content-Disposition'] = 'attachment; filename=%s' % file_name response['Content-Length'] = default_storage.size(file_path) return response </code></pre> <p>In case, when I am writing </p> <pre><code>print user_file </code></pre> <p>It returns a correct data, but when I am returning a HttpResponse it has a different data from a source</p>

    1. COYou should serve out the URI of the file, and let a real webserver (eg. Apache) serve static files. Also note that it is strongly recommended to check the uploaded file before saving, as far as security is concerned.

    3. COOnly one solution I am able to find at the moment: - after saving a file return a link to that file in a local filesystem - client (i.e. flash or something) will ask nginx for a static file

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.
