塔架:如何编写自定义404页面? [英] Pylons: How to write a custom 404 page?

问题描述

因此，这个问题 ，但没有详细回答.

So this question has been asked before, but not answered in great detail.

我想覆盖默认的Pylons错误页面，以创建更好的自定义页面.我已经覆盖了error.py中的控制器，如下所示:

I want to override the default Pylons error page to make a nicer, custom one. I've got as far as overwriting the controller in error.py, as follows:

def document(self):
    """Render the error document"""
    resp = request.environ.get('pylons.original_response')
    content = literal(resp.body) or cgi.escape(request.GET.get('message', ''))
    custom_error_template = literal("""\
    # some brief HTML here
    """)
    page = custom_error_template % \
        dict(prefix=request.environ.get('SCRIPT_NAME', ''),
             code=cgi.escape(request.GET.get('code', str(resp.status_int))),
             message=content)
    return page

这正常.我现在想做的是在模板目录中使用模板，以便404页面可以继承我通常的布局模板，CSS等.

This works OK. What I'd like to do now is use a template in the templates directory, so that the 404 page can inherit my usual layout template, CSS etc.

(我知道这对于500个错误是一个坏主意-在我使用模板而不是文字之前，我将在error.py中检查代码是否为404.)

(I know this is a bad idea for 500 errors - I'll check in error.py that the code is 404 before I use the template rather than a literal.)

所以，这是问题.如何定义custom_error_template指向模板而不是文字?

So, here's the question. How do I define custom_error_template to point at my template, rather than at a literal?

推荐答案

您应该能够使用render方法(从yourapp.lib.base导入它，然后使用return render('/path/to/error/template').

You should be able to use render method (import it from yourapp.lib.base, and use return render('/path/to/error/template').
