Python Django不会在通过POST提交的表单上重新执行代码

我为django的奇怪行为而发疯。 我在virtualenv中安装了以下软件包：

Django==1.6.10
South==1.0.2
argparse==1.2.1
dj-database-url==0.3.0
django-appconf==1.0.1
django-classy-tags==0.6.1
django-cms==3.0.12
django-compressor==1.4
django-debug-toolbar==1.3.0
django-extensions==1.5.1
django-mptt==0.6.1
django-reversion==1.8.5
django-sekizai==0.8.1
djangocms-admin-style==0.2.5
djangocms-column==1.5
djangocms-file==0.1
djangocms-flash==0.1
djangocms-googlemap==0.2
djangocms-inherit==0.1
djangocms-installer==0.7.2
djangocms-link==1.5
djangocms-picture==0.1
djangocms-style==1.5
djangocms-teaser==0.1
djangocms-text-ckeditor==2.4.3
djangocms-video==0.1
sorl-thumbnail==12.2
sqlparse==0.1.14
wsgiref==0.1.2

这些是我安装的应用程序：

INSTALLED_APPS = (
    'djangocms_admin_style',
    'djangocms_text_ckeditor',
    'django.contrib.auth',
    'django.contrib.contenttypes',

    'compressor',
    'django_extensions',
    'sorl.thumbnail',
    'cms_sorl_pictures',
    'cmsplugin_contact',

)

我在第83行更改了文件venv/local/lib/python2.7/site-packages/django/template/response.py：

...
    @property
    def rendered_content(self):
        """Returns the freshly rendered content for the template and context                                                                         
        described by the TemplateResponse.                                                                                                           

        This *does not* set the final content of the response. To set the                                                                            
        response content, you must either call render(), or set the                                                                                  
        content explicitly using the value of this property.                                                                                         
        """
        template = self.resolve_template(self.template_name)
        context = self.resolve_context(self.context_data)
        content = template.render(context)
        import ipdb; ipdb.set_trace()                                                                                                               
        return content
...

我启动服务器：

python manage.py runserver 0.0.0.0:8000
Validating models...

然后我打开URL/en gb/其中是cmsplugin_联系人的形式：

然后我按c键：

如果我坚持多次提交表单，它将执行代码并始终显示感谢模板。

我不明白问题出在哪里。

解决了为每个页面添加视图并删除：

url(r'^', include('cms.urls')),

从url.py
