Django：此函数的关键字参数无效 [英] Django: invalid keyword argument for this function

问题描述

我想将一些数据插入到多个字段中。我收到此错误

用户是此函数的无效关键字参数

我也尝试了相关的名称...但仍然没有工作...

我的模型看起来像这样： / p>

models.py

  class Workspace（models.Model）：
 user = models.ManyToManyField（User，null = False，blank = False，related_name ='members'）
 workspace_name = models.CharField（max_length = 80，null = False，blank = False）
 workspace_cat = models.CharField（max_length = 80，null = True，blank = True）
  

py

  db = Workspace（user = 5，workspace_name = data_to_db ['workspace_name']，workspace_cat = data_to_db ['workspace_category'] ）
 db.save（）
  

有人有想法吗？非常感谢！

解决方案

你使用了一个用户的/ref / models/fields/#django.db.models.ManyToManyField> ManyToMany 字段工作空间对象的c>字段，您不能给它一个用户，这不是一个 ManyToMany 的工作原理，那将是一个 ForeignKey 。

基本上，使用 ForeignKey ，每个工作区都有一个用户与它相关联，直接链接 Workspace - >用户，所以创建一个工作空间并将其传递给用户您将填写 CharField 。

A ManyToMany 关系意味着几个用户可以与 Workspace 和几个工作区关联到一个用户。当使用 ManyToMany 时，您将创建您的工作区和然后添加一些 User s。

要添加到 ManyToMany 请执行以下操作：

  my_user = User.objects.get（pk = 5）
 my_workspace = Workspace（workspace_name = data_to_db ['workspace_name']，workspace_cat = data_to_db ['workspace_category']）
 my_workspace.save（）＃首先对于DOM（Jurudocs编辑）是必需的。
 my_workspace.users.add（my_user ）
  

您应重命名用户字段到用户 ，使关系名称更清晰。

I want to insert some data into a many to many field. I 'm getting this Error

user is an invalid keyword argument for this function

i also tried it with the relatedName...but still is not working...

My model looks like this:

models.py

class Workspace(models.Model):
    user = models.ManyToManyField(User,null=False, blank=False, related_name='members')
    workspace_name = models.CharField(max_length=80, null=False, blank=False)
    workspace_cat =models.CharField(max_length=80, null=True, blank=True)

views.py

db= Workspace(user=5, workspace_name=data_to_db['workspace_name'],workspace_cat=data_to_db['workspace_category'])
db.save()

Does somebody has an idea? Thanks a lot!

解决方案

You used a ManyToMany field for the user field of your Workspace object, you can't give it one user, that's not how a ManyToMany works, that would be a ForeignKey.

Basically, using a ForeignKey, each workspace has one User associated to it, there's a direct link Workspace -> User, so it makes sense to create a Workspace and pass it an User, like you would be filling in a CharField.

A ManyToMany relationship means that several users can be associated to a Workspace and several Workspaces to one User. When using a ManyToMany, you would create your Workspace and then add some Users to it.

To add to a ManyToMany relationship, do the following:

my_user = User.objects.get(pk = 5)
my_workspace = Workspace(workspace_name=data_to_db['workspace_name'],workspace_cat=data_to_db['workspace_category'])
my_workspace.save() # committing to the DB first is necessary for M2M (Jurudocs edit)
my_workspace.users.add(my_user)

You should rename the user field to users to make the relationship name clearer.
