python - Django ModelForm 不保存数据

Question

我有一个用于在 footer.html 中订阅的表单，该表单包含在 base.html 中，因此该表单应该适用于网站上的每个页面。我为此使用了 context_processor 解决方案，一切正常，但是由于某种原因数据没有保存在数据库中。我花了几个小时在 Stack 上寻找合适的解决方案，但没有成功。

类似的问题是here ，但也不适合我。应该是简单的事情，但由于我是 django 的新手，所以有点复杂。请帮忙。提前致谢

注意:请确保将'catalogue.context_processors.SubscribeFormGlobal' 添加到设置中

models.py

from django.db import models


class Subscriber(models.Model):
    email = models.EmailField()

    def __str__(self):
        return self.email

forms.py

from django import forms
from .models import Subscriber


class SubscriberForm(forms.ModelForm):
    class Meta:
        model = Subscriber
        fields = ('email',)

context_processors.py

from .forms import SubscriberForm


def SubscribeFormGlobal(request):
    return {'subscribe_form': SubscriberForm()}

views.py

def subscribe_us(request):
    if request.method == "POST":
        subscribe_form = SubscriberForm(request.POST)
        if subscribe_form.is_valid():
            subscribe_form.save(commit=False)
            subscribe_form.author = request.user
            subscribe_form.published_date = timezone.now()
            subscribe_form.save()
    else:
        subscribe_form = SubscriberForm()
    return render(request, '', {'subscribe_form': subscribe_form})

urls.py

from catalogue import views
from catalogue.models import Bancnote

urlpatterns = [
    url(r'^$', views.bons_list, name='bons_list'),
    url(r'^(?P<pk>\d+)$', DetailView.as_view(model=Bancnote, template_name='catalogue/bon_detail.html')),
    url(r'^feedback/$', views.feedback, name='feedback'),
    url(r'^$', views.subscribe_us, name='subscribe')
]

Answer 1

您不能有两个具有相同 URL 模式的 View - 您在根 URL 上同时拥有 bons_list 和订阅。这意味着只有 bons_list View 被调用。

您需要给订阅者提供自己的 URL。

(当您这样做时，您会在提交时收到错误，因为 render 调用中的模板名称为空；不确定为什么要这样做，您需要提供一个模板来当表单无效时呈现。您还应该在表单有效时重定向；大概您会重定向回主页。)
