Django 视图未呈现 - 侧边栏和 header 加载正常但主要内容未加载

Question

我经历了很多不同的事情，我就是无法解决；需要一双新眼睛哈哈

我的视图没有呈现，这似乎是我的应用程序和登录页面的情况 - 侧边栏和 header 加载正常，页脚看起来部分加载但我相信这是由于以下事实主要内容未加载。

Answer 1

在您的案例 content.

中，您似乎正在使用 get() 方法将 context 添加到您的视图中

更改您的视图以使用 get_context_data() Django documentation.

例子views.py

# Recipe View
class RecipesView(LoginRequiredMixin, TemplateView):
    template_name = 'nf_recipes/recipes-database.html'

    def get_context_data(self, **kwargs):
        context = super(RecipesView, self).get_context_data(**kwargs)

        context.update({
            'heading': "Recipes Database",
            'pageview': "Recipes & Formulations"
        })

        return context

您可能还想检查您的 base.html 文件是否包含 {% block contents%} 标签

Answer 2

我的问题出在我的 base.html 文件中 - layout-wrapper 的分隔符似乎没有用 </div>.

关闭

遇到类似问题的任何人，请检查您的 HTML 的主要模板并检查是否所有分隔线都已正确关闭。
