Django admin：在django中获取登录的用户ID

Question

I am new to django and learnign it. I am using django's Auth and i need to get the id of the logged in user at some place. I have tried :

HttpRequest.user.id referring to the Django docs but this throws exception :

Exception Type: AttributeError
Exception Value: type object 'HttpRequest' has no attribute 'user' 

My code :

from django.http import HttpRequest
#...some other code here..#

class Post(models.Model):
     title = models.CharField(max_length=200)
     body = models.TextField('post body')
     author = models.ForeignKey(User)

     def save(self, force_insert=False, force_update=False, using=None, update_fields=None):
          self.author = HttpRequest.user.id
          super(Post, self).save(force_insert, force_update, using, update_fields) 

--UPDATE ---

I have also tried :

from django.http import request

and then in save method :

self.author = request.user.id

but it gives me exception -

Exception Type: AttributeError
Exception Value: 'module' object has no attribute 'user'

Answer 1

You shouldn't override the model's save() method, but override the admin save_model() method instead:

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

HttpRequest is a class , which doesn't have an user attribute. You need to obtain the request object , most likely from a view function. Then you can pass the user object, or its id to your model save() method:

def view_function(request):
     user = request.user
     # Get the object you want to save the user field to
     post = Post.objects.get(...) 
     post.user = user
     # Or post.user_id = user.id
     post.save()
     ... ...
