如何将数据添加到 ManyToMany 字段? [英] How to add data into ManyToMany field?

问题描述

我在任何地方都找不到它，所以你的帮助对我很有帮助:) 这是那个字段:

I can't find it anywhere, so your help will be nice for me :) Here is that field:

categories = models.ManyToManyField(fragmentCategory)

片段类别:

class fragmentCategory(models.Model):

        CATEGORY_CHOICES = (
                        ('val1', 'value1'),
                        ('val2', 'value2'),
                        ('val3', 'value3'),
                        )

        name = models.CharField(max_length=20, choices=CATEGORY_CHOICES)

这是要发送的表格:

<input type="checkbox" name="val1" />
<input type="checkbox" name="val2" />
<input type="checkbox" name="val3" />

我尝试过这样的事情:

I tried something like this:

categories = fragmentCategory.objects.get(id=1),

或者:

categories = [1,2]

推荐答案

有一整页 Django 文档 致力于此，从内容页面编入索引.

There's a whole page of the Django documentation devoted to this, well indexed from the contents page.

正如该页面所述，您需要执行以下操作:

As that page states, you need to do:

my_obj.categories.add(fragmentCategory.objects.get(id=1))

或

my_obj.categories.create(name='val1')
