    <p>I'm trying to upload a profile image in django and crop it on the server side using PIL. I've written a simple function that takes the file and crop areas as parameters, crops the image, and returns it. </p> <p>The problem I'm having is that the returned object does not have a file name and therefore django doesn't know how to save it. Here is the description from the django error page (AttributeError(name) was the error called):</p> <pre><code>/Library/Python/2.6/site-packages/PIL/Image.py in __getattr__ # numpy array interface support new = {} shape, typestr = _conv_type_shape(self) new['shape'] = shape new['typestr'] = typestr new['data'] = self.tostring() return new raise AttributeError(name) ... ## # Returns a string containing pixel data. # # @param encoder_name What encoder to use. The default is to # use the standard "raw" encoder. ▼ Local vars Variable Value self &lt;PIL.Image.Image image mode=RGB size=300x300 at 0x101FCACF8&gt; name '_committed' </code></pre> <p>You can see the image file object does not have a name attached to it like it normally would if uploaded directly from django. I've searched throughout the PIL docs and django docs, but haven't come up with anything that saves a name for the file (e.g., image.save("filename.jpg", "JPEG") didn't work). I'd like to save the file in memory and not have to deal with writing to a disk if possible.</p> <p>I can attach additional code if necessary, but I think/hope I'm just missing something simple with Python. I know there are libraries that will make this easier for me, but right now I'm just trying to understand the fundamentals of image handling with Python/django. Any ideas? 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.
