我在我的Django应用程序中使用python-social-auth通过Facebook进行身份验证.但是当用户尝试登录并且当它被重定向到Facebook应用页面点击"取消"按钮时,会出现以下异常:

通常,我使用dispatch基于类的视图的方法来设置一些初始变量或根据用户的权限添加一些逻辑.

例如,

from django.views.generic import FormView
from braces.views import LoginRequiredMixin

class GenerateReportView(LoginRequiredMixin, FormView):
    template_name = 'reporting/reporting_form.html'
    form_class = ReportForm

    def get_form(self, form_class):
        form = form_class(**self.get_form_kwargs())
        if not self.request.user.is_superuser:
            form.fields['report_type'].choices = [
                choice for choice in form.fields['report_type'].choices
                if choice[0] != INVOICE_REPORT
            ]
        return form

它按预期工作:当匿名用户访问页面时,调用LoginRequiredMixin的dispatch方法,然后将用户重定向到登录页面.

但是,如果我想为此视图添加一些权限或设置一些初始变量,例如,

class GenerateReportView(LoginRequiredMixin, FormView):

    def dispatch(self, *args, **kwargs):
        if not (
            self.request.user.is_superuser or
            self.request.user.is_manager
        ):
            raise Http404
        return super(GenerateReportView, self).dispatch(*args, **kwargs)

在某些情况下它不起作用,因为dispatch视图继承的mixins的方法尚未被调用.因此,例如,为了能够请求用户的权限,我必须重复以下验证LoginRequiredMixin:

class GenerateReportView(LoginRequiredMixin, FormView):

    def …

是否有可能pk从与网址相关的消除UpdateView？

例如,如果我有

url(r'^myobj/update/(?P<pk>\d+)/$', views.UpdateMyObj.as_view(), name="update")

有什么方法可以写它

url(r'^myobj/update/$', views.UpdateMyObj.as_view(), name="update")

然后pk作为参数发送POST或GET请求？

我正在尝试将QuickTip添加到表单字段,但找不到让我的代码工作的方法.首先,我尝试使用qtip属性

    {
        fieldLabel: 'Last Name',
        qtip:'This tip is not showing at all',
        name: 'last'
    }

然后使用Ext.tip.ToolTip类:

Ext.create('Ext.tip.ToolTip', {
    target: 'rating_field',
    anchor: 'right',
    trackMouse: true,
    html: 'This tip is not showing at all'
});

Ext.QuickTips.init();

我正在使用python-social-auth我的Django应用程序登录社交网络.在我的本地机器上一切正常,但当我部署到服务器时,我收到以下错误:

oauthlib.oauth1.rfc5849.utils in escape

我在我的项目中使用python-social-auth和电子邮件注册.对于用户模型,我使用AbstractBaseUser的子类:

class User(AbstractBaseUser):
    USERNAME_FIELD = 'email'


AUTH_USER_MODEL = 'userprofile.User'

但是,如果用他的电子邮件注册的用户(demo@demo.com)和密码尝试使用与同一电子邮件地址关联的Facebook帐户登录,则会收到以下错误:

IntegrityError at /social/complete/facebook/
duplicate key value violates unique constraint "userprofile_user_email_key"
DETAIL:  Key (email)=(demo@demo.com) already exists.

我正在尝试有条件地在我的页面上包含聊天：

<body ng-app="myApp">
  <!-- some code -->

  <script type="text/javascript" ng-if="expression">
    window.$zopim||(function(d,s){var z=$zopim=function(c){z._.push(c)},$=z.s=
    d.createElement(s),e=d.getElementsByTagName(s)[0];z.set=function(o){z.set.
    _.push(o)};z._=[];z.set._=[];$.async=!0;$.setAttribute("charset","utf-8");
    $.src="//v2.zopim.com/?my-zopim-id";z.t=+new Date;$.
    type="text/javascript";e.parentNode.insertBefore($,e)})(document,"script");
  </script>
</body>

但聊天脚本似乎是在ng-if指令之前执行的。

如何让我的 Angular 应用程序首先检查条件，然后从<script>标签执行脚本？

我必须通过外键连接模型

class User(AbstractUser):
   ...

和

class PrivateMessage(models.Model):
    user_from = models.ForeignKey(
        User,
        verbose_name=u'From',
        related_name='sent_messages',
    )
    user_to = models.ForeignKey(
        User,
        verbose_name=u'To',
        related_name='received_messages',
    )

有没有办法获取特定用户的所有地址。例如，如果

u = User.objects.get(id=1)
messages = PrivateMessage.objects.filter(user_from=u)
for m in messages:
    users.add(m.user_to)

如何user_to仅使用 Django ORM 方法获取出现在这些消息中的用户列表？

我的页面上有一个表单,包含textarea(CKEDITOR)和select字段<select id="_photogalleries" multiple="multiple"></select>.我希望RichCombo中的选项依赖于select with id中选择的选项#_photogalleries.有没有办法动态重新生成RichCombo？提前致谢.

        requires: ['richcombo'],
        init: function(editor) {
            var pluginName = 'style_plugin';
            var config = editor.config,
                lang = editor.lang.format;

            editor.ui.addRichCombo('photogalleries', {
                label: "????????????",
                title: "????????????",
                voiceLabel: "????????????",
                className: 'cke_format',
                multiSelect: false,
                icon: CKEDITOR.plugins.getPath('style_plugin') + 'photo-list-horizontal.png',

                panel: {
                    css: [config.contentsCss, CKEDITOR.getUrl(editor.skinPath + 'editor.css')],
                    voiceLabel: lang.panelVoiceLabel
                },

                init: function () {
                    this.startGroup("????????????");
                    var list=this;
                    $("#_photogalleries option:selected").each(function(index, value){
                        console.log(index, value);
                        list.add("#HORIZONTAL_GALLERY_"+ $(value).val()+"#", "(?) " + $(value).text(), "(?) " + $(value).text());

我的 Rails 项目中有很多 RSpec 测试，用于测试对外部 REST API 的 HTTP 调用，并使用 VCR 磁带记录请求和响应。目前我的 VCR 配置如下：

VCR.configure do |c|
  c.cassette_library_dir = 'spec/vcr_cassettes'
  c.hook_into :webmock
  c.configure_rspec_metadata!
end

因此请求匹配规则仅匹配 HTTP 方法和 URI。我想更改此设置以匹配请求正文：

VCR.configure do |c|
  c.cassette_library_dir = 'spec/vcr_cassettes'
  c.hook_into :webmock
  c.configure_rspec_metadata!
  c.default_cassette_options = {
    :match_requests_on => [:uri, :method, :body],
  }
end

但由于我的项目中已经有很多测试，我想逐步进行，仅对某些测试激活此新限制，这样其他测试（使用旧磁带）就不会中断。

有没有办法将参数传递给 RSpec 测试，以便仅针对某些特定测试或测试组制定自定义请求匹配规则？

我想象类似的事情

it 'reverts transaction', :vcr, :body_matching => true do
    # something
end

然后根据body_matching参数动态更改设置。
