Get All Fields in a Model

Say for example you have the following model:

from django import models

class Book(models.Model):
    title = models.CharField(max_length=255)
    author = models.ForeignKey(Author)
    date_published = models.DateTimeField(default=datetime.datetime.now())

Then you wanted to get all fields or field names of the Book model.

Solution:

You can actually do two things.

First:
If you wanted to get all fields as an object, you can add the following as a method in your Book model:

def get_model_fields(self):
    return self._meta.fields

Second:
If you wanted to get all field names of the Book model, then you can add the following method:

def get_model_field_names(self):
    return self._meta.get_all_field_names()

Note:

There is a big difference between the two methods above. The first one returns a list of objects based on Book model while the second one returns a list of strings so use them according to your needs.
