Please give one or two specific examples of functionality you need. There are parameters for fields which can help specialize some behaviours without needing a new model. And there are hooks to allow specialization of behaviours in interpretation or handling when reading or saving values which you may find useful.

afaik there is no large library of model specializations for Django, but that may be because there is no clear large set of specializations that would be useful.

So give an example please. Is it the book name, the book author, or something else which needs extra or restricted behaviours?

This is an example. Where did the get all these parameter like CharField, DateTimeField etc.

 

class Item(models.Model):
    name = models.CharField(max_length=60)
    created = models.DateTimeField(auto_now_add=True)
    priority = models.IntegerField(default=0)
    difficulty = models.IntegerField(default=0)
    done = models.BooleanField(default=False)

class ItemAdmin(admin.ModelAdmin):
    list_display = ["name", "priority", "difficulty", "created", "done"]
    search_fields = ["name"]

admin.site.register(Item, ItemAdmin)

Hi Mr. Akumbo,

The options for Model Fields that come with django in the django.db library and are listed and explained here: https://docs.djangoproject.com/en/dev/ref/models/fields/#model-field-types

Each corresponds to a different type of data. For example

name = models.CharField(max_length=60)

just means that the the database will store a 60-character text string (VARCHAR).

Other libraries can define other field types. For example, the https://pypi.python.org/pypi/django-localflavor package has Model fields specific to different nations such as localflavor.za.forms.ZAPostCodeField for South African postal codes. If you really need to, you can look at the source code of that project for an example of defining your own.

It sounds like you are working through someone else's django project but would find some broader context useful. If you haven't already, I would recommend working through the tutorial, starting here:

https://docs.djangoproject.com/en/dev/intro/tutorial01/

best regards,

Andrew Farrell

Thanks for this reply , am not using anybody's code. I am still studying django and was wondering where those fields where from. Thanks for the clarification. With time i will write my own field since am from Cameroon.
