如何使用{}为模板的部分禁用Jinja2? [英] How to disable Jinja2 for sections of template with {}?

问题描述

我通过复制/粘贴他们在其网站上提供的代码在页面上添加了一个Facebook按钮.

I added a facebook button to my page by copying/pasting the code they supply on their website.

它看起来像这样:

"http://www.facebook.com/dialog/feed?app_id={{fbapp_id}}&link={{link_url}}&message={{share_message|urlencode}}&display=popup&redirect_uri={{link_url}}  

如您所见，在其中找到了Jinja的{}.但是，由于我不希望将以上任何代码替换为任何东西，因此我可以在模板中添加一些内容，以指示Jinja忽略定界符之间的所有内容吗?

As you can see, it's got the {} in there that Jinja looks for. However, being that I don't want any of the above code replaced with anything, is there something I can add into my template which tells Jinja to ignore everything between the delimiters?

Python处理程序:

Python Handler:

class MainHandler(webapp2.RequestHandler):
    def get(self):
        template = JINJA_ENV.get_template('index.html')
        self.response.write(template.render(None))

推荐答案

您通常可以找到该信息在文档的转义"下或类似内容.在这种情况下，您可以输出带有变量表达式的定界符:

You can usually find that information in the documentation, under "Escaping" or similar. In this case, you can either output the delimiter with a variable expression:

{{ '{{' }}

或者您可以使用raw块来获取更长的代码段:

Or you can use the raw block, for longer stretches of code:

{% raw %}
    <ul>
    {% for item in seq %}
        <li>{{ item }}</li>
    {% endfor %}
    </ul>
{% endraw %}
