Common fields for different django models in one place-CodePudding

I have some columns that are repeated in multiple models. is there any solution to place them somewhere and use it any model?

CodePudding user response：

You can achieve this by creating base classes and inheriting them in your models.

Example:

class TimestampsModel(models.Model):

    @classmethod
    def get_fields(cls, fields: tuple):
        return fields.__add__(('created_at', 'updated_at'))
    
    created_at = models.DateTimeField(("created_at"), auto_now_add=True)
    updated_at = models.DateTimeField(("updated_at"), auto_now=True)

You can also make it abstract and Django won't create migrations for this.

    class Meta:
        abstract = True

Finally, a model would be:

class Blog(baseModels.TimestampsModel):

    class Meta:
        db_table = "blog"

    title = models.CharField(max_length=100)
