render_to_response给出TemplateDoesNotExist [英] render_to_response gives TemplateDoesNotExist

问题描述

我正在使用

paymenthtml = os.path.join(os.path.dirname(__file__), 'template\\payment.html')

并在另一个应用程序中调用
paymenthtml被复制到payment_template

and calling it in another application where paymenthtml gets copied to payment_template

return render_to_response(self.payment_template, self.context, RequestContext(self.request))

但是我收到错误

TemplateDoesNotExist at / test-payment-url /

TemplateDoesNotExist at /test-payment-url/

E：\testapp\template\payment.html

E:\testapp\template\payment.html

为什么会出现错误？

编辑：我在settings.py中进行了以下更改，可以找到模板，但是我无法对生产中的路径进行硬编码，任何线索？

Edit : I have made following change in settings.py and it is able to find the template, but i cannot hardcode the path in production, any clue?

TEMPLATE_DIRS = ("E:/testapp" )

推荐答案

似乎Django只会加载模板，如果它们位于您在 TEMPLATE_DIRS 中定义的目录中，即使它们存在于其他位置。

It seems like Django will only load templates if they're in a directory you define in TEMPLATE_DIRS, even if they exist elsewhere.

尝试此在settings.py：

Try this in settings.py:

PROJECT_ROOT = os.path.abspath(os.path.dirname(__file__))
# Other settings...
TEMPLATE_DIRS = (
    os.path.join(PROJECT_ROOT, "templates"),
)

然后在视图中：

return render_to_response("payment.html", self.context, RequestContext(self.request))
# or
return render_to_response("subdir/payment.html", self.context, RequestContext(self.request))

这将呈现 E：\path\to\project\templates\\ \\ payment.html 或 E：\path\to\project\templates\subdir\payment.html 。关键是它们在我们在settings.py中指定的目录中。

This would render either E:\path\to\project\templates\payment.html or E:\path\to\project\templates\subdir\payment.html. The point is that they're inside of the directory we specified in settings.py.
