在Flask中一次渲染多个模板 [英] Render multiple templates at once in Flask
问题描述
我正在制作Flask应用程序.我有一个登录区域，一个博客区域.如果要获取用户的登录名，我将呈现登录模板.但这不会呈现必须显示在登录区域下方的博客模板.:/
I'm making a Flask application. I have a login area, a blogs area. If I want to get user's login, I'll render login template. But this doesn't render the blog template that has to be displayed below the login area. :/
我会尝试使其更清晰:
{% block login %} {% endblock %}
blah blah
{% block blog_display %} {% endblock %}
现在我有一个 login.html ，它对此进行了扩展，并进入了登录块.我有一个 blogs.html ，它进入了 blog_display .如何同时渲染两者?当我执行 render_template()时，只能在 login.html 或 blogs.html 之一上调用它.
Now i have a login.html which extends this, and goes into login block. I have a blogs.html which goes into blog_display. How to I render both? When I do render_template(), i can call it on only one of the login.html or blogs.html.
请帮帮我.如果您需要，我会提供更多详细信息.
Please help me out. I'll give more details if you ask for it.
推荐答案
您可能会以错误的方式考虑布局.布局是模板的 most 通用模板，而不是最复杂的模板.如果您需要很少的独立功能，则可以按原样编写它们，并按和 <在需要的地方添加代码>包含 .
You may be thinking about layouts the wrong way. Your layout is the most generic of your templates, not your most complex one. If you need little self-contained pieces of functionality then write them up just as they are and include them where they are needed.
也就是说，如果您想要这样的东西:
That is to say, if you want something like this:
----------------------------------
+--------------+
Header | Login |
+--------------+
----------------------------------
Body Content (Blog)
您还希望拥有一个独立的登录页面，如下所示:
And you also want to have a stand-alone login page like this:
----------------------------------
Header
----------------------------------
+--------------+
| Login |
+--------------+
然后创建部分登录名，并在需要的地方 include .
Then create a login partial and include it where you need it.
templates/partials/login.html
<form action="/login" method="post">
<!-- Your login goes here -->
</form>
templates/your_base.html
<!DOCTYPE html>
<html>
<head>
{% block head %}
{#
Default HEAD content goes here
with extra nested blocks for children to override
if needed.
#}
{% endblock head %}
</head>
<body>
<header>{% block header %}{% endblock header %}</header>
{# Note: This assumes we *always* want a header #}
{% block content %}{% endblock content %}
</body>
</html>
templates/login.html
{% extends "your_base.html" -%}
{% block content -%}
{% include "partials/login.html" %}
{%- endblock content %}
templates/blog.html
{% extends "your_base.html" -%}
{% block header -%}
{{ super() }}{# Render the default header contents here #}
{% include "partials/login.html" %}
{%- endblock header %}
{% block content -%}
{# Render your blog posts here #}
{%- endblock content %}
