在模板中添加视图

问题描述

在django中，我有一个观点，填写一个模板html文件，但是在html模板内部我想包含另一个使用不同的html模板的视图：

In django I have a view that fills in a template html file but inside the html template I want to include another view that uses a different html template like so:

{% block content %}
Hey {{stuff}} {{stuff2}}!

{{ view.that_other_function }}

{% endblock content %}

这是可能吗？

推荐答案

是的，你需要使用模板标签来做到这一点。如果您需要做的只是渲染另一个模板，则可以使用包含标记，或者可能只是内置{％include'path / to / template.html'％}

Yes, you need to use a template tag to do that. If all you need to do is render another template, you can use an inclusion tag, or possibly just the built in {% include 'path/to/template.html' %}

模板标签可以在Python中做任何事情。

Template tags can do anything you can do in Python.

您可以使用render_to_string方法：

[Followup]You can use the render_to_string method:

from django.template.loader import render_to_string
content = render_to_string(template_name, dictionary, context_instance)

您需要解决请求对象从上下文中，或者如果需要使用context_instance，则将其作为参数传递给模板标签。

You'll either need to resolve the request object from the context, or hand it in as an argument to your template tag if you need to leverage the context_instance.

跟进答案：包含标签示例

Followup Answer: Inclusion tag example

Django希望模板标签生活在名为templatetags的文件夹中，该文件夹位于应用程序模块这是你安装的应用程序...

Django expects template tags to live in a folder called 'templatetags' that is in an app module that is in your installed apps...

/my_project/
    /my_app/
        __init__.py
        /templatetags/
            __init__.py
            my_tags.py

#my_tags.py
from django import template

register = template.Library()

@register.inclusion_tag('other_template.html')
def say_hello(takes_context=True):
    return {'name' : 'John'}

#other_template.html
{% if request.user.is_anonymous %}
{# Our inclusion tag accepts a context, which gives us access to the request #}
    <p>Hello, Guest.</p>
{% else %}
    <p>Hello, {{ name }}.</p>
{% endif %}

#main_template.html
{% load my_tags %}
<p>Blah, blah, blah {% say_hello %}</p>

包含标记根据需要呈现另一个模板，但无需调用视图功能。希望能让你走。关于包含标签的文档位于：

The inclusion tag renders another template, like you need, but without having to call a view function. Hope that gets you going. The docs on inclusion tags are at: http://docs.djangoproject.com/en/1.3/howto/custom-template-tags/#inclusion-tags
