Order and sanity for django model choices.
Documentation is a work in progress.
To install with pip:
$ pip install django-choices
To install with easy_install:
$ easy_install django-choices
To start you create a choices class. Then you point the choices property on your fields to the choices attribute of the new class. Django will be able to use the choices and you will be able to access the values by name. For example you can replace this:
# In models.py class Person(models.Model): # Choices PERSON_TYPE = ( ("C", "Customer"), ("E", "Employee"), ("G", "Groundhog"), ) # Fields name = models.CharField(max_length=32) type = models.CharField(max_length=1, choices=PERSON_TYPE)
# In models.py from djchoices import DjangoChoices, ChoiceItem class Person(models.Model): # Choices class PersonType(DjangoChoices): Customer = ChoiceItem("C") Employee = ChoiceItem("E") Groundhog = ChoiceItem("G") # Fields name = models.CharField(max_length=32) type = models.CharField(max_length=1, choices=PersonType.choices, validators=[PersonType.validator])
You can use this elsewhere like this:
# Other code Person.create(name="Phil", type=Person.PersonType.Groundhog)
You can use without value, and the label will be used as value:
class Sample(DjangoChoices): OptionA = ChoiceItem() OptionB = ChoiceItem() print(Sample.OptionA) # "OptionA"
The DjangoChoices classes can be located anywhere you want. If I have a lot of declarations I will sometimes place them in a const.py or choices.py.
