在模板中使用 Django 视图变量 [英] Using Django view variables inside templates

问题描述

这是一个相当基本的问题(我是 Django 的新手)，但我在模板中使用视图中的变量集时遇到问题.如果我在视图中初始化一个字符串或列表(即 h = "hello")，然后尝试在模板中调用它:
{{ h }}
既没有输出也没有错误.同样，如果我尝试在模板中使用一个不存在的变量:

this is a rather basic question (I'm new to Django) but I'm having trouble using a variable set in my view inside my template. If I initialize a string or list inside my view (i.e. h = "hello") and then attempt to call it inside a template:
{{ h }}
there is neither output nor errors. Similarly, if I try to use a variable inside my template that doesn't exist:

{{ asdfdsadf }}

再次没有报告错误.这是正常的吗?以及如何在模板中使用我的变量.谢谢！

there is again no error reported. Is this normal? And how can I use my variables within my templates. Thanks!

推荐答案

为了访问模板中的变量，它需要位于用于呈现该模板的上下文中.我的猜测是您在渲染模板时没有将上下文字典传递给模板.

In order to have access to a variable in a template, it needs to be in the the context used to render that template. My guess is you aren't passing a context dictionary to the template when you render it.

http://docs.djangoproject.com/en/dev/topics/http/shortcuts/#render-to-response

此处引用的字典"是一个字典，其中包含您希望在上下文中可用的所有变量.例如:

The "dictionary" referenced there is a dictionary that contains all the variables you want to have available in the context. For example:

return render_to_response('your_template.html', {'h': h})

就无错误"错误而言......这是无效模板变量的默认设置.如果您愿意，您可以在项目的设置中更改它.

As far as the "no error" error goes... That's the default setting for an invalid template variable. You can change that in the project's settings if you'd like.
