Django URL模板标签添加了绝对文件路径 [英] Django url template tags adding absolute filepath

问题描述

我遇到了一个问题，我的{％url％} django模板标记正在将文件路径添加到生产环境中的网址.这不会复制到我的本地开发计算机上.

I am having a problem where my {% url %} django template tag is adding the filepath to the web address in production. This is not replicated on my local development machine.

使用urls.py设置，例如:

With urls.py setup such that:

url("^about_us/$", views.about_us, name="about_us"),

在生产中，我正在获取链接 www.mysite.com/home/username/myapp/about_us 代替 www.mysite.com/about_us

In production, I am getting the link www.mysite.com/home/username/myapp/about_us instead of www.mysite.com/about_us

我看过这个类似的问题，它对我的​​特定应用程序无济于事: Django url标签添加文件路径

I have looked at this similar issue and it does not help with my specific application: Django url tag adds filepath

我的django项目托管在使用Apache，wsgi和passenger的A2(共享)托管上.我的.htaccess文件如下所示:

My django project is hosted on A2 (shared) hosting using apache, wsgi, and passenger. My .htaccess file look the following:

# DO NOT REMOVE. CLOUDLINUX PASSENGER CONFIGURATION BEGIN 
PassengerAppRoot "/home/user/myapp"
PassengerBaseURI "/"
PassengerPython "/home/user/virtualenv/myapp/2.7/bin/python2.7"
# DO NOT REMOVE. CLOUDLINUX PASSENGER CONFIGURATION END

我的passenger_wsgi.py文件如下所示:

My passenger_wsgi.py file looks like the following:

import myapp.wsgi
SCRIPT_NAME = '/home/user/myapp'

class PassengerPathInfoFix(object):
    """
    Sets PATH_INFO from REQUEST_URI because Passenger doesn't provide it.
    """
    def __init__(self, app):
        self.app = app

    def __call__(self, environ, start_response):
        from urlparse import unquote
        environ['SCRIPT_NAME'] = SCRIPT_NAME

        request_uri = unquote(environ['REQUEST_URI'])
        script_name = unquote(environ.get('SCRIPT_NAME', ''))
        offset = request_uri.startswith(script_name) and len(environ['SCRIPT_NAME']) or 0
        environ['PATH_INFO'] = request_uri[offset:].split('?', 1)[0]
        return self.app(environ, start_response)

application = myapp.wsgi.application
application = PassengerPathInfoFix(application)

我感觉这些文件之一中的某些内容有问题.如何从链接中删除/home/user/myapp?

I feel like something is off in one of these files. How can I get remove the /home/user/myapp from my links?

更新:我想我已经解决了这个问题.当我将passenger_wsgi.py中的SCRIPT_NAME变量更改为

Update: I thought I figured out this problem. When I change the SCRIPT_NAME variable in passenger_wsgi.py to

SCRIPT_NAME = '.'

这最初可以在我转到主页时解决此问题.但是，一个新问题导致，如果您访问www.mysite.com/about_us，则{％url％}标签将导致

This initially fixes the problem when I go to the home page. However, a new problem results in that if you go to www.mysite.com/about_us, then the {% url %} tag will result in

www.mysite.com/about_us/about_us

www.mysite.com/about_us/about_us

也许这将为解决方案提供一些指导.

Maybe this will provide some direction to the solution.

更新#2 :我确实发现了这一点: https://smartlazycoding.com/django-tutorial/将django网站部署到a2托管

Update #2: I did find this: https://smartlazycoding.com/django-tutorial/deploy-a-django-website-to-a2-hosting

在此网站上，将passenger_wsgi.py文件更改为

From this website, changing the passenger_wsgi.py file to

import os
import sys
# set variables
sys.path.append(os.getcwd())
os.environ['DJANGO_SETTINGS_MODULE'] = 'project_name.settings'
#setup django application
import django.core.handlers.wsgi
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

解决了该问题，但是您仍然遇到它描述的POST问题.然后，我进行了网站建议的更改:

fixes the issue, but then you still have the POST issue it describes. I then made the changes the website recommends:

import os
import sys
# Set up paths and environment variables
sys.path.append(os.getcwd())
os.environ['DJANGO_SETTINGS_MODULE'] = 'project_name.settings'
import django.core.handlers.wsgi
from django.core.wsgi import get_wsgi_application
SCRIPT_NAME = os.getcwd()
class PassengerPathInfoFix(object):
    def __init__(self, app):
        self.app = app
    def __call__(self, environ, start_response):
        from urllib import unquote
        environ['SCRIPT_NAME'] = SCRIPT_NAME
        request_uri = unquote(environ['REQUEST_URI'])
        script_name = unquote(environ.get('SCRIPT_NAME', ''))
        offset = request_uri.startswith(script_name) and len(environ['SCRIPT_NAME']) or 0
        environ['PATH_INFO'] = request_uri[offset:].split('?', 1)[0]
        return self.app(environ, start_response)
application = get_wsgi_application()
application = PassengerPathInfoFix(application)

这导致了我原来的问题.

This results back into my original problem.

推荐答案

我有一个目前似乎有效的答案.解决方案基本上是上面发布的原始passenger_wsgi.py文件，但是将SCRIPT_NAME设置为一个空字符串.我的passenger_wsgi.py文件如下所示:

I have an answer that appears to work for now. The solution is basically the original passenger_wsgi.py file posted above, but setting SCRIPT_NAME equal to an empty string. My passenger_wsgi.py file looks like the following:

import myapp.wsgi
#SCRIPT_NAME = '/home/user/myapp'
SCRIPT_NAME = ''

class PassengerPathInfoFix(object):
    """
    Sets PATH_INFO from REQUEST_URI because Passenger doesn't provide it.
    """
    def __init__(self, app):
        self.app = app

    def __call__(self, environ, start_response):
        from urllib import unquote
        environ['SCRIPT_NAME'] = SCRIPT_NAME

        request_uri = unquote(environ['REQUEST_URI'])
        script_name = unquote(environ.get('SCRIPT_NAME', ''))
        offset = request_uri.startswith(script_name) and len(environ['SCRIPT_NAME']) or 0
        environ['PATH_INFO'] = request_uri[offset:].split('?', 1)[0]
        return self.app(environ, start_response)

application = myapp.wsgi.application
application = PassengerPathInfoFix(application)

这可以解决我的路径问题，并且可以使用POST.我不知道是否在应用程序的根路径上设置了SCRIPT_NAME =''的警告，但是如果有人知道这样做的任何问题，请分享.

This fixes my path issue and I am able to use POST. I don't know if there are any caveats of setting SCRIPT_NAME = '' over the app's root path, but if anyone knows of any issues of doing this, please share.
