问题描述
我在任何地方都找不到它,所以您的帮助对我非常有用:)这是该字段:
I can't find it anywhere, so your help will be nice for me :) Here is that field:
categories = models.ManyToManyField(fragmentCategory)
FragmentCategory:
FragmentCategory:
class fragmentCategory(models.Model):
CATEGORY_CHOICES = (
('val1', 'value1'),
('val2', 'value2'),
('val3', 'value3'),
)
name = models.CharField(max_length=20, choices=CATEGORY_CHOICES)
以下是发送表格:
<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:
categories = [1,2]
推荐答案
整个Django文档的页面专门为此,并在内容页面中对其进行了索引。
There's a whole page of the Django documentation devoted to this, well indexed from the contents page.
如该页面所示,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')
