哈尔滨网站设计模板wordpress添加订阅会员

只显示了自定义模板的内容，左侧导航没有显示出来。

原因：context 漏掉了，要补上。

# 错误写法（左侧导航不显示）def changelist_view(self, request, extra_context=None):form = CsvImportForm()payload = {"form": form}return TemplateResponse(request, "admin/csv_form.html", payload)# 正确写法：========================def changelist_view(self, request, extra_context=None):form = CsvImportForm()# 我要用的内容# 引入原有的内容context = dict(# Include common variables for rendering the admin template.self.admin_site.each_context(request),  # side nav was not loading because this was not added.# Anything else you want in the context...# key=value,form= form        # 加上我要用的内容)return TemplateResponse(request, "admin/csv_form.html", context)
