推荐答案
在 Django 1.8+,模板的 render
方法接受 context
参数的字典.支持传递 Context
实例 已弃用,并在 Django 1.10+ 中出现错误.
In Django 1.8+, the template's render
method takes a dictionary for the context
parameter. Support for passing a Context
instance is deprecated, and gives an error in Django 1.10+.
在您的情况下,只需使用常规 dict
而不是 Context
实例:
In your case, just use a regular dict
instead of a Context
instance:
message = get_template('email_forms/direct_donation_form_email.html').render(ctx)
您可能更喜欢使用 render_to_string
快捷方式:
You may prefer to use the render_to_string
shortcut:
from django.template.loader import render_to_string
message = render_to_string('email_forms/direct_donation_form_email.html', ctx)
如果您使用的是 RequestContext
而不是 Context
,那么您还要将 request
传递给这些方法,以便上下文处理器运行.
If you were using RequestContext
instead of Context
, then you would pass the request
to these methods as well so that the context processors run.
message = get_template('email_forms/direct_donation_form_email.html').render(ctx, request=request)
message = render_to_string('email_forms/direct_donation_form_email.html', ctx, request=request)
