关于 Django 在我的模型中访问和保存用户外键的问题

我看到类似的问题已经被问过但我想知道是否有更简单的方法来实现这一目标。

下面给出了一个示例模型。

class Post (models.Model):
    name = models.CharField(max_length=1000, help_text="required, name of the post")
    description = models.TextField(blank=True)
    created_datetime = models.DateTimeField(auto_now_add=True, editable=False)
    modified_datetime = models.DateTimeField(auto_now=True, editable=False)
    custom_hashed_url = models.CharField(unique=True, max_length=1000, editable=False)

def save(self, *args, **kwargs):
        #How to save User here?
        super(Model, self).save()

在调用 save() 之前是否可以将当前登录的用户发送到模型？

视图中：

if request.method == 'POST':

if not errors:

    f = PostForm(request.POST)

    f.save()

I see that similar to this has been asked before but I would like to know if there was a simpler way to achieve this.

Also followed this blog post.

A sample Model is given below.

class Post (models.Model):
    name = models.CharField(max_length=1000, help_text="required, name of the post")
    description = models.TextField(blank=True)
    created_datetime = models.DateTimeField(auto_now_add=True, editable=False)
    modified_datetime = models.DateTimeField(auto_now=True, editable=False)
    custom_hashed_url = models.CharField(unique=True, max_length=1000, editable=False)

def save(self, *args, **kwargs):
        #How to save User here?
        super(Model, self).save()

Isn't it possible to send current logged in user to the Model before calling save()?

In the view:

if request.method == 'POST':

if not errors:

    f = PostForm(request.POST)

    f.save()

鉴于您已使用 django-admin 对其进行了标记，我假设您希望保存通过管理界面修改对象的用户。（您实际上无法在模型的 save 方法中执行此操作，因为它不一定有权访问 User 对象 - 例如，如果您从 shell 接口保存对象怎么办？）

要在 Django 管理中执行此操作，只需覆盖 ModelAdmin 的 save_model 方法：

class PostAdmin(admin.ModelAdmin):
    def save_model(self, request, obj, form, change):
        obj.user = request.user
        obj.save()

admin.site.register(Post, PostAdmin)

当然，您需要实际添加一个名为 ForeignKey code>user 到您的模型才能正常工作...

Given that you've tagged this with django-admin, I'll assume you're wishing to save the User who is modifying the object via the admin interface. (You can't really do it in your model's save method, because it doesn't necessarily have access to a User object -- e.g. what if you're saving an object from a shell interface?)

To do this within Django's admin, simply override the save_model method of your ModelAdmin:

class PostAdmin(admin.ModelAdmin):
    def save_model(self, request, obj, form, change):
        obj.user = request.user
        obj.save()

admin.site.register(Post, PostAdmin)

Of course, you would need to actually add a ForeignKey named user to your model for that to work...
