Django ContextMixin“super”对象没有属性“get_context_data”

Question

我需要将一些上下文传递给多个视图中的模板。上下文是使用一些用户的信息从BD获取的，所以我实现了一个特定的ContextMixin类：

class CampaignContextMixin(ContextMixin):
"""
This mixin returns context with info related to user's campaign.
It can be used in any view that needs campaign-related info to a template.
"""
def get_campaigns(self):
    # Get the first campaign related to user, can be more in the future
    return self.request.user.campaign_set.all()

# Method Overwritten to pass campaign data to template context
def get_context_data(self, **kwargs):
    context = super(CampaignContextMixin).get_context_data(**kwargs)
    campaign = self.get_campaigns()[0]
    context['campaign_name'] = campaign.name
    context['campaign_start_date'] = campaign.start_date
    context['campaign_end_date'] = campaign.end_date
    context['org_name'] = self.request.user.organization.name
    context['campaign_image'] = campaign.image.url
    context['campaign_details'] = campaign.details
    return context

然后我试图在我的视图中使用它，但是我得到了一个错误：

'super' object has no attribute 'get_context_data'

^{pr2}$

我不确定是因为继承错误，还是因为TemplateView继承了ContextMixin。我的目标是重用将活动信息添加到上下文中的代码。在

谢谢

你是说

super(CampaignContextMixin, self).get_context_data(**kwargs)
#super().get_context_data(**kwargs)  > python3
