如何在数据库中没有ForeignKey的情况下执行ManyToOne？

Question

eb_config_object = models.ForeignKey(EbConfig, on_delete=models.CASCADE)

I want to serialize an object, which includes another object. But the problem is in my design concept I can not allow ForeignKey(Hard foreign key) exist in my database(MySQL).

Is there any method to perform that in Django2.x?

Answer 1

eb_config_object = models.ForeignKey(EbConfig, on_delete=models.CASCADE, db_constraint=False)

When I post this question, I had known the attributes(db_constraint) of ForeignKey.But I failed to get through the SQL automatic generated by Django. It tells me can not find a field.

Just migrate your models to physical database by manage.py, and all works.You can get all the benifits from ForeignKey which is given by Django, and there is no any physical ForeignKey in your database.
