如何将dict值分配给user_id以创建对象

Question

def insertCompany_type(request):
          if request.method == 'POST':
             try:
                data = json.loads(request.body)
                c_type = data["subject"]
                user = get_user_id(request)
                print user
                c_ty=Company_Type(user_id=user,type=c_type)
                c_ty.save(force_insert=True)
             except:
                     print 'nope'
          return JsonResponse({'status': 'success'})

print user

displays [{'user_id': 1L}]

.. How can i assign 1 to user_id in Company_Type(user_id=user,type=c_type) for creating objects

Answer 1

When you actually make a user (which doesnt happen your snippet of code) you can pass a constuctor argument setting user_id. eg

myUser = User(name="shalin", user_id=1)
myUser.save()

Also, you can get user objects from requests simply by doing this:

user = request.user

which is a bit easier than what you're doing I think.

Answer 2

If user is a list of length 1, containing a dict, you can extract the value of a dict as follows:

value = user[0]['user_id']

You could modify your code as:

      if request.method == 'POST':
         try:
            data = json.loads(request.body)
            c_type = data["subject"]
            user = get_user_id(request)
            id = user[0]['user_id']
            c_ty=Company_Type(user_id=id,type=c_type)
            c_ty.save(force_insert=True)
         except:
                 print 'nope'
      return JsonResponse({'status': 'success'})

Also if you need to make sure the id is an integer cast it to the right data type as int(id)
