Using Multiple ModelForms with Class-Based Views

问题 I've got a situation where I'd like to add an additional modelform to my CreateView. We have an entry order system that allows someone to add an order and then add items to that order. Typically, when someone adds an order for the first time they'd like to also add an item to that order, so I want to combine those models into a single form and process them on initial order entry. I'm running into a problem when the forms don't validate. I've overridden get_context_data to add the item form to

问题 I'm currently learning how to use the class-based views in django 1.3. I'm trying to update an application to use them, but I still don't uderstand very well how they work (and I read the entire class-based views reference like two or three times EVERY day).

Class-based and Object-based languages comparison (ECMAScript Specification)

由 久未见 提交于 2019-12-12 07:38:28
问题 In a class-based object-oriented language, in general, state is carried by instances, methods are carried by classes, and inheritance is only of structure and behaviour. In ECMAScript, the state and methods are carried by objects, while structure, behaviour, and state are all inherited. This is the snippet from ECMAScript Specification June 2015. I don't understant parts of this text. State is carried by instances - what does state mean in this context and example of this (c++ is preferred)

Django: CreateView with additional field?

由 无人久伴 提交于 2019-12-07 07:10:24
问题 I am trying to program a Django CreateView (CBV), which takes instead of the user id the user email and determines (or creates) the user based on the email.

My forms.py adds the additional email field to the form: class ProjectCreateForm(forms.ModelForm): email = forms.EmailField(required=True, ) class Meta:

由 旧街凉风 提交于 2019-12-06 08:29:02
问题 Reading a 'ProDjango' book, I've found interesting moment about applying custom decorator to methods in class-based views.
