Django 1.11 TypeError上下文必須是字典而不是上下文

Question

剛剛在我的某個表單上收到了Sentry錯誤TypeError context must be a dict rather than Context.。我知道這與Django 1.11有關，但我不確定要修改它。

問題的行

message = get_template('email_forms/direct_donation_form_email.html').render(Context(ctx))

在Django 1.8+，模板的render方法需要一本字典爲context參數。支持傳遞Context實例is deprecated，並在Django 1.10+中給出錯誤。

在你的情況下，只需使用常規dict代替Context實例：

message = get_template('email_forms/direct_donation_form_email.html').render(ctx) 

您可能更願意使用render_to_string快捷：

from django.template.loader import render_to_string 

message = render_to_string('email_forms/direct_donation_form_email.html', ctx)
