自定义金字塔错误消息

发布于 2024-11-24 15:42:52 字数 1023 浏览 0 评论 0原文

我正在尝试找到一种在金字塔应用程序中自定义错误消息（404、403）的方法。我找到了此文档，但目前还不清楚如何做到这一点。

我需要做什么来呈现模板之一（例如 templates/404.pt）而不是标准 404 消息。我在我的 __init__.py 中添加了以下内容：

from pyramid.config import Configurator
from pyramid.httpexceptions import HTTPNotFound

import myapp.views.errors as error_views

<...>

def main(global_config, **settings):
    config = Configurator(settings=settings)
    config.add_static_view('static', 'myapp:static')
    config.add_route(...)
    <...>
    config.add_view(error_views.notfound, context=HTTPNotFound)
    return config.make_wsgi_app()

其中 error_views.notfound 看起来像

def notfound(request):
    macros = get_template('../templates/macros.pt')
    return {
            'macros': macros,
            'title': "HTTP error 404"
            }

当然它不起作用（在这种情况下如何指定模板名称？），甚至更多：看起来视图是根本没有被调用并且它的代码被忽略。

I'm trying to find a way to customize error messages (404, 403) in my Pyramid application. I've found this doc, but it's still not clear how to do it.

What I need to do it to render one of the templates (say, templates/404.pt) instead of standard 404 message. I've added following to my __init__.py:

from pyramid.config import Configurator
from pyramid.httpexceptions import HTTPNotFound

import myapp.views.errors as error_views

<...>

def main(global_config, **settings):
    config = Configurator(settings=settings)
    config.add_static_view('static', 'myapp:static')
    config.add_route(...)
    <...>
    config.add_view(error_views.notfound, context=HTTPNotFound)
    return config.make_wsgi_app()

Where error_views.notfound looks like

def notfound(request):
    macros = get_template('../templates/macros.pt')
    return {
            'macros': macros,
            'title': "HTTP error 404"
            }

Sure it does not works (how do I specify template name in this case?), and even more: it seems view is not called at all and it's code ignored.

您应该将 pyramid.exceptions 异常作为上下文传递给 add_view，而不是 pyramid.httpexceptions 异常。

这对我有用：

def main(global_config, **settings):
    """
    This function returns a Pyramid WSGI application.
    """
    ...
    config.add_view('my_app.error_views.not_found_view',
        renderer='myapp:templates/not_found.pt',
        context='pyramid.exceptions.NotFound')

You should pass to add_view as context a pyramid.exceptions exception, not a pyramid.httpexceptionsone.

This works for me:

def main(global_config, **settings):
    """
    This function returns a Pyramid WSGI application.
    """
    ...
    config.add_view('my_app.error_views.not_found_view',
        renderer='myapp:templates/not_found.pt',
        context='pyramid.exceptions.NotFound')

将其放入您的 myapp.views.errors 文件中：

from pyramid.renderers import render_to_response

def notfound(request):
    context['title'] = "HTTP error 404"
    return render_to_response('../templates/macros.pt', context)

让我知道这是否适合您。

Put this in your myapp.views.errors file:

from pyramid.renderers import render_to_response

def notfound(request):
    context['title'] = "HTTP error 404"
    return render_to_response('../templates/macros.pt', context)

Let me know if this works for you.

从 Pyramid 1.3 开始，使用 @notfound_view_config 装饰器就足够了。现在不需要在 __init__.py 中设置任何内容。有views.py的示例代码：

from pyramid.view import notfound_view_config
@notfound_view_config(renderer='error-page.mako')
def notfound(request):
    request.response.status = 404
    return {}

From Pyramid 1.3 it's enough to use @notfound_view_config decorator. There is no need to set anything in __init__.py now. There is example code for views.py:

from pyramid.view import notfound_view_config
@notfound_view_config(renderer='error-page.mako')
def notfound(request):
    request.response.status = 404
    return {}
