Django {% include %} TemplateDoesNotExist at /blog/includes/post.html答案

【问题描述】：

你好，祝你有美好的一天，

我目前正在学习 Django 课程，我正在建立一个博客。

我不断收到：

TemplateDoesNotExist 在 / 博客/includes/post.html

我似乎无法解决。

但我认为它与 {%include%} 模板标签有关

我有两个文件： 1)post.html 和 2)index.html

我正在尝试 {%include%} index.html 中的 post.html

但是当我这样做时：

TemplateDoesNotExist 在 / blog/includes/post.html 模板不存在错误

但我已经多次测试了路径我检查了 settings.py 并且我的路径是正确的

{% include "blog/includes/post.html" %} ### HERE IS THE PROBLEM in index.html
{% include "blog/post.html" %}
{% include "blog/templates/blog/includes/post.html" %}

我已经尝试了所有路径都不起作用。

我可以使它工作的唯一方法是不使用 {% include%} 而是直接复制和粘贴 post.html 但这是不切实际的，不会让我继续我的项目

这是目录结构：

blog/templates/blog/includes/post.html

blog /templates / blog /index.html

##### index.html   ######

{% extends "templates/base.html" %} 
{% load static %}

{% block title %} 
My Blog 
{% endblock %} 

{% block css_files %}
  <link rel="stylesheet" href="{% static "blog/post.css" %}" />
  <link rel="stylesheet" href="{% static "blog/index.css" %}" />
{% endblock %}

{% block content %}
<section id="welcome">
  <header>
    <img src="{% static "blog/images/.png" %}" alt="myblog" />
    <h2>BLOG</h2>
  </header>
  <p>Hi, I love to blog about tech and the world!</p>
</section>

<section id="latest-posts">
  <h2>My Latest Thoughts</h2>

  <ul>
    {% include "blog/includes/post.html" %}### HERE IS THE PROBLEM 
  </ul>
</section>

<section id="about">
  <h2>What I Do</h2>
  <p>
     programming is fun 
  </p>
  <p>
    hello this is  my blog 
  </p>
</section>
{% endblock %}

####  post.html  ####

{% extends "templates/base.html" %} 
{% load static %}


<li>
  <article class="post">
    <a href="{% url "post-detail-page" post.slug %}">
      <img src="{% static "blog/images/"|add:post.image %}" alt="{{ post.title }}"
      />
      <div class="post__content">
        <h3>{{ post.title }}</h3>
        <p>
          {{ post.excerpt }}
        </p>
      </div>
    </a>
  </article>
</li>

【问题讨论】：

问题出在你的模板目录中，你的目录 blog/include/ 中有 post.html 吗？
可以分享模板的文件目录结构
文件目录如下：blog/templates/blog/includes/post.html
和博客/templates/博客/index.html
在 index.html 中使用 {% include "includes/post.html" %}

标签： html python-3.x django templates django-templates

【解决方案1】：

尝试更改settings.py：

TEMPLATES = [
    ...
    'DIRS': [str.format(BASE_DIR, "/templates")]
    ...

到这里：

TEMPLATES = [
    ...
    'DIRS': ["templates/"]
    ...

再试一次：

{% include "blog/includes/post.html" %}

【讨论】：

这不起作用，它继续返回我上面列出的相同的引用，模板渲染时出错在模板/home/jo/My_site/templates/base.html中，错误在第 0 行 blog/includes/post.html
从post.html 中删除{% extends "templates/base.html" %}。你要延长两次。
我如你所说的那样删除了，我只是添加了扩展以查看这是否是问题，我也得到了这一行：上述异常（blog/includes/post.html）是直接原因以下异常：本地变量 /home/jo/My_site/blog/views.py，第 75 行，在starting_page ** **
