问题 I'm struggling to get my head round django forms.. I've been reading various documentation but just can't quite grasp the concepts. I have got to grips with models, views and templates. What I am trying to do is to create a form with various fields composing of dropdown lists and checkboxes which are populated by values in a database. I have a working app called vms. Using the models.py I have a built a simple schema that holds size and type. Size consists of 'small', 'medium' & 'large'. Type

问题 I have a model with a field for a json object. This object is used on the site to control some css variables, among other things. Right now in the admin, I have a text field where a user can save a json object. I'd like to show a form with all the attributes that, upon saving, will generate a json object. Basically, the user sees, and the data is stored, like this: { "name":"hookedonwinter", "user-id":123, "basics":{ "height":150, "weight":150 } } And I'd rather have the user see this: Name:

问题 Could anyone explain to me similarities and differences of Django's forms.Form & forms.ModelForm ? 回答1: Forms created from forms.Form are manually configured by you. You're better off using these for forms that do not directly interact with models.

问题 I created a formset that has maximum of 5 images to be attached; 1 - but I want the Validation to run only when the user has not attached any image (ValidationError('atleast 1 image is required')) , 2- This program is also not allowing the User to save when 1, or 2, or 3 images are attached, which I really need. So if there is 1 image or 2, that should be allowed to save. 3 - I also need to make the 1 radio-button to be selected by default, to make the selected image to be the one dispalyed

问题 models.py: class Foo(models.Model): ... TIME_UNIT_TYPE = ( ('D', 'Day'), ('W', 'Week'), ('M', 'Month'), ) time_unit = models.CharField(max_length=1, choices=TIME_UNIT_TYPE) ... forms.py: class FooForm(ModelForm): class Meta: model = Foo fields = (time_unit,) When time_unit is rendered in the template, the resultant select element contains a bogus '----' option that I don't need for my app. I can remove this bogus option inside init () or redefine the time_unit attribute inside the FooForm.

问题 I have a form with which I want to update a MyModel object. On the model there is a unique_together constraint, fieldA together with fieldB.
