    <p>I need to save files, not from request.FILES, but from another saved record.</p> <p>Here's the code for the model record:</p> <pre><code>class Foo(models.Model) slug = models.SlugField() class FooFile(models.Model): name = models.CharField(max_length=100) file = models.FileField(upload_to='foo_folder') foo = models.ForeignKey(Foo, related_name='files') class RealRecord(models.Model): slug = models.SlugField() awesome_file=models.FileField(upload_to='awesome') mediocre_file=models.FileField(upload_to='mediocre') </code></pre> <p>And the view (in this case <code>MyForm</code> is a model form that saves to RealRecord):</p> <pre><code>def example(request, record=1, template_name="form.html") foo_obj = Foo.objects.get(pk=record) SAVED_FILES = {} for file in foo_obj.files.all(): SAVED_FILES[file.name]=file.file if request.method == 'POST': form = MyForm(data=request.POST, files=SAVED_FILES) if form.is_valid(): form.save() # rest of view else: form = MyForm() return render(request, template_name, locals()) </code></pre> <p>So the thing is basically a <code>FieldFile</code> is being used as an <code>UploadedFile</code> object. </p> <p>Each <code>Foo</code> will have a <code>FooFile</code> record with the name <code>awesome_file</code> and another with the name <code>mediocre_file</code>, matching up with the required fields in <code>RealRecord</code>.</p> <p>The crazy thing is, this totally validates. <em>However</em>, the problem is that in the resulting record that is created, both awesome_file and mediocre_file have their path in "foo_folder". But I don't want the files in "foo_folder", I want them to be in the path that I specified for each field in <code>RealRecord</code>.</p> <p>So I guess I am wondering what I can do to the <code>FieldFile</code> values coming from <code>FooField</code> so that they behave like a traditional UploadedFile and get the <code>upload_to</code> and <code>path</code> values of their respective fields.</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.
