Hi all, Here’s an issue of usability that if fixed could make usage of custom fields simpler.
Right now fields don’t allow a built-in defaults, and you need to explicitly set the default parameter for model fields. The problem is that this adds a ton of boilerplate code. Using the Polls tutorial example, if I do: >>> from polls.models import Question, Choice >>> q = Question() By default it’s always <class 'NoneType’>: >>> type(q.pub_date) <class 'NoneType'> The pub_date should always be a type <class 'datetime.datetime'>. If this was defined in the model constructor, then we could start to access the datetime.datetime class immediately, to assign data. If I had a custom datetime.datetime class, I could possibly do this immediately: >>> q = Question() >>> q.pub_date.month = 11 >>> q.pub_date.day = 26 >>> q.pub_date.year = 2016 >>> q.save() But right it would give the following error: >>> q.pub_date.year = 2016 Traceback (most recent call last): File "<console>", line 1, in <module> AttributeError: 'NoneType' object has no attribute 'year' Is this a reasonable request? I’m able to do something like this now with my own custom fields that derive from models.SubfieldBase, but that class is deprecated, and the new 1.8 model initializer doesn’t do this anymore.
