Django没有将表单提交到数据库

用例是登录使用,可以将他们的个人资料调到表格中,编辑它并在数据库中更新。

使用下面的代码可以查看正确的配置文件数据。它也可以被称为可编辑的形式。表单允许编辑数据,但在提交时,数据库不会更新,并显示原始配置文件。

我已经尝试了所有内容,包括控制台打印语句,所以我知道它正在进入代码的POST部分,是一个有效的表单并执行初始save()。

任何见解都将受到赞赏(我正在使用Django 1.11)。我不想开始运行兔子,但我唯一没有尝试的是打破OneToOne与User的关系并使用foriegnkey因为我希望在用户注册时创建配置文件条目。

备注: 当我将其打开以进行测试时:save_data.user = request.user 我收到错误:异常值:'用户'对象没有来自django.db导入模型的属性'cleaning_data'` 来自django.contrib.auth.models导入用户 来自django.db.models.signals导入post_save

Models.py

    from django.db import models
from django.contrib.auth.models import User
from django.db.models.signals import post_save

class UserProfile(models.Model):
    user = models.OneToOneField(User)
    description = models.CharField(max_length=100, default='')
    city = models.CharField(max_length=100, default='')
    website = models.URLField(default='')
    phone = models.IntegerField(default=0)
    balance = models.FloatField(default=0)
    bank  = models.FloatField(default=0)
    image = models.ImageField(upload_to='profile_image', blank=True)

    def __str__(self):
        return self.user.username

def create_profile(sender, **kwargs):
    if kwargs['created']:
        user_profile = UserProfile.objects.create(user=kwargs['instance'])

post_save.connect(create_profile, sender=User)

from django.contrib.auth.models import User
from .models import UserProfile

class ProfileForm(forms.ModelForm):
    class Meta:
        model = UserProfile
        fields = ('description', 'city', 'phone', 'balance', 'bank', 'website', 'image')

        if form.is_valid():
            save_data = form.save()
            save_data.user = request.user

urls.py

from django.conf.urls import url
from django.contrib import admin
#from playme.core import views as core_views
from core import views as core_views

# SET THE NAMESPACE!
app_name = 'core'


urlpatterns = [
    url(r'^$', core_views.index, name='index'),
    url(r'signup/$', core_views.signup, name='signup'),
    url(r'^account/$', core_views.account, name='account'),

    url(r'^edit_profile/$', core_views.edit_profile, name='edit_profile'),
    url(r'^change_password/$', core_views.change_password, name='change_password'),
]

我要点击的网址是: http://127.0.0.1:8000/play/profile/ 然后去: http://127.0.0.1:8000/play/edit_profile/

表单加载但提交时返回到: http://127.0.0.1:8000/play/profile/

没有数据库更新。

我很惊讶这不会给出错误。

当您在GET上实例化表单时,您正确地将UserProfile对象作为if (colorsApproximatelyEqual(color, FIELD_GREEN, 0.1)) { // process click on field... } 参数传递 - 这是正确的,因为表单将其作为模型。但是当您在POST上实例化时,您错误地传递了User对象 - instance。您应该像在其他分支中那样传递配置文件。

请注意,在这两种情况下,只需执行request.user即可更简单地获取个人资料。

表格无效的情况根本没有在这里处理。您的代码应如下所示

def edit_profile(request):
    if request.method == 'POST':
        form = ProfileForm(request.POST, instance=request.user)
        if form.is_valid():
            save_data = form.save(commit=False)
            save_data.user = request.user
            save_data.save()
            return redirect(reverse('core:profile'))
    else:
        udata = UserProfile.objects.get(user=request.user)
        form = ProfileForm(instance=udata)
        args = {'form': form}
    return render(request, 'core/test.html', args)

请注意缩进的更改。
