Python Django-Mongoengine：在用户对象中存储额外信息

我决定在我的用户对象（创建用户时的对象）中保存关于其他内容的额外数据，并存储一些关于我心目中想法的信息

问题是，我不知道如果创建一个自定义模型或将寄存器添加到我创建的文档中，什么会更好

我不知道mongoengine中的自定义用户模型，但我尝试在用户对象中添加一些额外的字段。我可以很容易地在mongo控制台中添加它，但是我在使用Django视图时遇到了麻烦，所以我尝试了类似的方法，但没有成功

我的模型看起来像：

from django.db import models
from mongoengine import *
class User(Document):
        username = StringField(max_length=120, required=True)
        password = StringField(max_length=120, required=True)
        email = StringField(max_length=120, required=True)
        my_extra_field= StringField(max_length=120, required=False)

和my forms.py看起来像

from django import forms
from captcha.fields import CaptchaField
class PostForm(forms.Form):
    user = forms.CharField(max_length=256)
    password = forms.CharField(widget=forms.PasswordInput)
    email = forms.CharField(max_length=256)
    #my_extra_field is not defined because is a fixed value and no need to introduce in the form

def post_form_upload(request):
    if request.method == 'GET':
        form = PostForm()
    else:
        # A POST request: Handle Form Upload
        form = PostForm(request.POST) # Bind data from request.POST into a PostForm

        # If data is valid, proceeds to create a new post and redirect the user
        if form.is_valid():
            user = form.cleaned_data['user']
            password = form.cleaned_data['password']
            email = form.cleaned_data['email']
            my_extra_field = 500
            connect('reborn')
            m = User.create_user(user,password,email)
            m.gold=500
            m.save()
            return HttpResponse(m)
            e.gold = 500
            e.save()
            #john.save()
            #return HttpResponse("Usuari nou creat")
            return render(request, 'game/welcomeuser.html', {
                'user': user,
            })
    return render(request, 'game/post_form_upload.html', {
        'form': form,
    })

这就是我遇到麻烦时的观点

from django import forms
from captcha.fields import CaptchaField
class PostForm(forms.Form):
    user = forms.CharField(max_length=256)
    password = forms.CharField(widget=forms.PasswordInput)
    email = forms.CharField(max_length=256)
    #my_extra_field is not defined because is a fixed value and no need to introduce in the form

def post_form_upload(request):
    if request.method == 'GET':
        form = PostForm()
    else:
        # A POST request: Handle Form Upload
        form = PostForm(request.POST) # Bind data from request.POST into a PostForm

        # If data is valid, proceeds to create a new post and redirect the user
        if form.is_valid():
            user = form.cleaned_data['user']
            password = form.cleaned_data['password']
            email = form.cleaned_data['email']
            my_extra_field = 500
            connect('reborn')
            m = User.create_user(user,password,email)
            m.gold=500
            m.save()
            return HttpResponse(m)
            e.gold = 500
            e.save()
            #john.save()
            #return HttpResponse("Usuari nou creat")
            return render(request, 'game/welcomeuser.html', {
                'user': user,
            })
    return render(request, 'game/post_form_upload.html', {
        'form': form,
    })

我尝试了不同的方法，但总是出错，因此：

备选案文1：

if form.is_valid():
                user = form.cleaned_data['user']
                password = form.cleaned_data['password']
                email = form.cleaned_data['email']
                my_extra_field = 500
                connect('reborn')
                m = User.create_user(user,password,email,my_extra_field) 
                ...

给出了4个参数和5个参数的误差

备选案文2：

if form.is_valid():
                user = form.cleaned_data['user']
                password = form.cleaned_data['password']
                email = form.cleaned_data['email']
                connect('reborn')
                m = User.create_user(user,password,email)
                m.gold=500
                m.save()
                return HttpResponse(m)
                e.gold = 500
                e.save()
                #john.save()
                #return HttpResponse("Usuari nou creat")
                return render(request, 'game/welcomeuser.html', {
                    'user': user,
                })

给出错误“保存不是用户对象的方法”

不知道如何解决这个问题！！我阅读了手册，但在readthedocs.com托管的mongoengine文档中找不到解决方案

您使用的是mongoengine.django.auth.User。它包含用户模型的公共字段，如

• 名字
• 姓
• 密码
• 用户名

如果需要，可以通过这种方式添加更多字段

from mongoengine.django.auth import User
from mongoengine import *

class MyUser(User):
    sex = StringField(default='M',max_length=1)# M-> male, F-> female       
    date_of_birth = DateTimeField()
    [...]
