How to use ModelForm for both new or existing data

Hi, I'm having trouble figuring out the best way to use ModelForm in the following situation. I have these post variables coming into the view course_id course_department course_number And course_id may or may not be an empty string. If I do course_form = CourseForm(request.POST) Then the

Admin TabularInline Edit Parent Record?

I use TabularInlines for Many-to-Many join tables, with the foreign keys appearing in select lists. The Admin interface automatically provides the stellar "Add-Another" icon (a plus sign) with the select list, to add a new parent record on the fly. It would be extremely useful to also have an edit

Never mind. I've found the answer. The problem was that my app name "messages" somehow clashed with the app "django.contrib.messages" which was earlier in my INSTALLED_APPS. This didn't prevent my project from working, but did confuse the test framework, which looked in

Re: Beginner's unit test question

I'm sorry for my inconsistency. I tried to "simplify", but made a mistake. In fact, I used the app "messages" throughout, in my code and in the test command. The project containing the app works fine. In particular, the app "messages" is included in INSTALLED_APPS. So, if the test "should

You could use a model with three fields: A generic foreign key to the instance to be modified. A char field containing the fieldname on that instance. The new value. Of course you'd need another field to store the user (assuming the person making the authorization will base their

DecimalField values changing on save()

Hi all I know this is a bit of a corner case, but I was slightly surprised by the behaviour of DecimalField with the value -0.0. Given the model: class Word(models.Model): word = models.CharField(max_length=50, unique=True) number = models.DecimalField(max_digits=8, decimal_places=5)

Use primary key in filenames on FileFields

Hello, I have a model that includes a FileField. When the user uploads a file via the admin interface, I want the file to be saved as 'upload_to/ primary_key/original_filename'. Since the object will not be saved in the database when the user uploads the file, it will not have a primary key at
