Django 管理员从模型中选择框选项

Question

我有语言类别、标签和问题模型。添加问题时，我想在管理面板的多选下拉/复选框中选择类别和多个标签 这是我的问题模型：

from django.db import models
from datetime import datetime
from languages.models import Language
from categories.models import Category
from tags.models import Tag


class Question(models.Model):
language = models.ForeignKey(Language, on_delete=models.DO_NOTHING)
category = models.ForeignKey(Category, on_delete=models.DO_NOTHING)
tags = models.CharField(max_length=200, blank=True)

def __str__(self):
    return self.title

如何在 Django 管理面板中实现这一点？

Answer 1

为此，我认为您可以使用ManyToManyField。像这样：

from django.db import models
from datetime import datetime
from languages.models import Language
from categories.models import Category
from tags.models import Tag


class Question(models.Model):

    language = models.ForeignKey(Language, on_delete=models.DO_NOTHING)
    category = models.ForeignKey(Category, on_delete=models.DO_NOTHING)
    tags = models.ManyToManyField(Tag)

    def __str__(self):
        return self.title
