views.py：您必须将

表单

传递给模板，以便它可以显示在

main

html中，并调用

form.save（）

将数据保存到数据库中

假设您有appurl.py如下所示：

def content_get(request):                                                                                                                                                                                      
   if request.method == 'POST':                                                                                                                                                                           
      form = ContentForm(request.POST)
      if form.is_valid():                                                          
           instance = form.save()
           return HttpResponse('create success')
      else:
           return HttpResponse(forms.errors)
   else:                                                                               
      return render(request, 'main.html', {'form':form})

<form action = '/content_get/' method = 'post'>                                                                       
  {% csrf_token %}

  <input type = 'submit' value = 'Submit' />                                                              
</form>

from django.conf.urls import url

from . import views

app_name = 'post'

urlpatterns = [
    url(r'^$', views.post, name='main'),
    url(r'^content$', views.content_get, name='content_get'),
]

最后，在main.html中，您需要定义要发布的

action

：

def content_get(request):                                                                                                                                                                                      
   if request.method == 'POST':                                                                                                                                                                           
      form = ContentForm(request.POST)
      if form.is_valid():                                                          
           instance = form.save()
           return HttpResponse('create success')
      else:
           return HttpResponse(forms.errors)
   else:                                                                               
      return render(request, 'main.html', {'form':form})

<form action = '/content_get/' method = 'post'>

  <input type = 'submit' value = 'Submit' />                                                              
</form>

    {% endfor %}

正如您所说，我对其进行了更改，但我试图将表单提交内容保留在主页上，而不是转到其他url。我将如何实现这一点？这将我重定向到/content，我认为我需要创建或更改它。但它解决了我的主要问题。您可以使用

重定向

，它将重定向到您想要的任何url，如主url。检查更新的答案。
