Django 1.11 TypeError上下文必须是字典而不是Context [英] Django 1.11 TypeError context must be a dict rather than Context

问题描述

刚刚收到哨兵错误 TypeError上下文必须是字典而不是Context。在我的一种表单上。我知道它与Django 1.11有关，但我不确定要对其进行更改以进行修复。

Just received the Sentry error TypeError context must be a dict rather than Context. on one of my forms. I know it has something to do with Django 1.11, but I am not sure what to change to fix it.

推荐答案

在 Django 1.8+ ，模板的 render 方法采用上下文参数的字典。支持传递 Context 实例已弃用，并且在Django 1.10+中给出了错误。

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，只需使用常规的 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)

如果使用 RequestContext 而不是 Context ，那么您将传递 request 这些

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)
