问题描述
目前我的代码中有很多 python 对象,类似于以下内容:
Currently I have a lot of python objects in my code similar to the following:
class MyClass():
def __init__(self, name, friends):
self.myName = name
self.myFriends = [str(x) for x in friends]
现在我想把它变成一个 Django 模型,其中 self.myName 是一个字符串字段,self.myFriends 是一个字符串列表.
Now I want to turn this into a Django model, where self.myName is a string field, and self.myFriends is a list of strings.
from django.db import models
class myDjangoModelClass():
myName = models.CharField(max_length=64)
myFriends = ??? # what goes here?
由于列表是 Python 中的一种常见数据结构,我有点期望有一个 Django 模型字段.我知道我可以使用 ManyToMany 或 OneToMany 关系,但我希望在代码中避免这种额外的间接性.
Since the list is such a common data structure in python, I sort of expected there to be a Django model field for it. I know I can use a ManyToMany or OneToMany relationship, but I was hoping to avoid that extra indirection in the code.

推荐答案
将这种关系表示为 Friends
表的一对多外键关系不是更好吗?我知道 myFriends
只是字符串,但我认为更好的设计是创建一个 Friend
模型并让 MyClass
包含一个外键与结果表的关系.
Would this relationship not be better expressed as a one-to-many foreign key relationship to a Friends
table? I understand that myFriends
are just strings but I would think that a better design would be to create a Friend
model and have MyClass
contain a foreign key realtionship to the resulting table.
