问题 I'm working with Django 1.4 FormWizard (specifically, NamedUrlFormWizard) first, the basics. i have a 3 step form wizard i'm building. The final outcome is along the lines of defining a template, and then choosing some people to use it, and then send them an email. Step 1 - enter in basic template data (name, description, etc) Step 2 - define a list of N fields, each with their own set of attributes but all identical in structure Step 3 - choose one or more users to email, AND customize the

(Sort of a "Copy" then "Paste With Modifications" setup.) This works fine except with File Fields and the ClearableFileInput widget. The answers to questions like this, this, and this make it clear that file fields can't and shouldn't be populated with an initial value. The Django docs, however, on the

问题 I have an inline formset that only has three fields: class Estimate_Product_Details(models.Model): proposalID = models.ForeignKey(Estimate_Construction, verbose_name='Proposal ID') CID = models.ForeignKey(Product, verbose_name = 'CID') qty = models.DecimalField(max_digits = 7, decimal_places = 2, verbose_name = 'Quantity') def __unicode__(self): return u'%s -- %s' % (self.proposalID, self.CID) I then create a form from that model: class Product_Form(ModelForm): class Meta: model = Estimate

问题 I am using the TemporaryFileUploadHandler to upload files. If a user is uploading a large file and cancels the upload, the file remains in my temporary directory. Is there a way to trap a cancelled upload (connection reset before a file was fully uploaded) in order to cleanup these files?
