Some links in drop-down menu not working when using mod_wsgi

[Tim de Wit]

I've succesfully moved from using runserver to hosting within apache (v2.4.12-2ubuntu2.1). Until now everything seems to work, except several links in the config menu.
Most links inside base.html are prefixed with /openrem/ except:

<li><a href="/admin/auth/user/">Manage users</a></li>
<li><a href="/admin/patientidsettings/1/">Patient ID settings</a> </li>

<a href="/logout/" class="navbar-link">logout</a>
<a href="/login/?next={{ request.get_full_path|urlencode }}" class="navbar-link">login</a>

Furthermore, I'm hosting the openrem app from url: http://myhostname/openrem but I can imagine that a customized subfolder, e.g. http://myhostname/openrem_testserver won't work, when using these hardcoded paths?

[Tim de Wit]

Same applies for the "/login" link on line 61 of home.html

[Tim de Wit]

Yet another related issue i came across (please tell me if I should have created another issue). On the index site, the login link is set wrongly when the url doesn't contain a trailing slash. Apparently request.get_full_path returns the wrong path. Examples:

http://myhostname/openrem --- request.get_full_path = /
http://myhostname/openrem/ --- request.get_full_path = /openrem/

Consequently, after logging in, I'm redirected to the wrong page.

btw:
As a quick fix of my first comment, i prefixed the url with "/openrem":
<a href="/openrem/login/?next={{ request.get_full_path|urlencode }}">

Hi @tcdewit

I'm not entirely sure why those URLs aren't resolving for you, though I will agree the URL structure is a little messy.

Some /admin URLs are django rather than OpenREM as such, so are outside of the /openrem/ 'app'. For example this applies to /admin/auth etc.

Others are part of the openrem app, but I've used the same path. However, these will resolve with or without the openrem element. For example /admin/patientidsettings/1/ is the same as /openrem/admin/patientidsettings/1/.

The reason for this is the URL file in openremproject is consulted first, then this points initially to remapp.urls for anything (r'^'), again for URLs with openrem in (r'^openrem/') and then if the URL still hasn't been matched it is passed to admin.site.urls which is part of the core django install (r'^admin/'). Finally there are URL matches for URLs that end in login or logout (r'^login/$' and r'^logout/$') which lead to django.contrib.auth.views.login and remapp.views.logout_page respectively.

In terms of the trailing slash, I haven't been able to replicate this as in both Chrome and IE11 a trailing slash is added automatically when the page loads.

With respect to custom subfolder names, I would think it might work with if the two installs are in different folders as long as the apache config was right. However, when doing test installs, are you not likely to be using the built-in runserver with a custom port? In which case by varying the port you can have as many as you like that don't conflct (though RabbitMQ might get a bit messy!)

[Tim de Wit]

Hi Ed,

Thanks for the explanation. I'm wondering... which test-setup do you use? Only runserver? Or do you have openrem served by apache as well? If so, perhaps we could share configurations? Maybe it's something i configured wrongly in apache.

Modifying the auth-link to /openrem/admin/auth seems to work as well, so for the moment I'm using that, but I'd rather see a generic version. Maybe I'll look further into the URL-file and remapp.urls to get it working.

As for the trailing slash: IE8, IE11, Chrome 49.0.2623.87 and Chrome 54.0.2840.59 show the same behavior here (slash not added automatically), so it doesn't seem to be browser-related. Did you customize a lot (e.g. settings.py, urls.py) compared to the version on bitbucket?

[Ed McDonagh]

No, no customisations vs bitbucket. But I am using gunicorn and nginx rather than Apache. No proper reason why, but I did! I followed these instructions.

I don't have a test setup on my production server. All my development work is on my laptop, using runserver, and occasionally I throw up a lxd container on one of the servers and use runserver on that generally.

[David Platten]

Hi Tim. I have OpenREM running under Apache 2.4 on Windows Server 2012. My admin-based links work OK. I'm happy to share config files - what version of Apache are you using?

[Tim de Wit]

Hi David, that would be great! I'm running 2.4.12-2ubuntu2.1, so more or less the same version, but under linux. Do you have openrem in your documentroot or in a subfolder like me?

[Ed McDonagh]

If you are in a subfolder, does that mean you end up with URLs like myserver.me/openrem/openrem/ct/?

[Tim de Wit]

My documentroot is /var/www/mysite and:
WSGIScriptAlias /openrem "/usr/local/lib/python2.7/dist-packages/openrem/openremproject/wsgi.py"
so my urls are like: myserver.me/openrem/ct

[David Platten]

Here's my full http.conf file - note the "Alias", "WSGIScriptAlias" and "WSGIPythonPath" lines near the end:

#
# This is the main Apache HTTP server configuration file.  It contains the
# configuration directives that give the server its instructions.
# See <URL:http://httpd.apache.org/docs/2.4/> for detailed information.
# In particular, see 
# <URL:http://httpd.apache.org/docs/2.4/mod/directives.html>
# for a discussion of each configuration directive.
#
# Do NOT simply read the instructions in here without understanding
# what they do.  They're here only as hints or reminders.  If you are unsure
# consult the online docs. You have been warned.  
#
# Configuration and logfile names: If the filenames you specify for many
# of the server's control files begin with "/" (or "drive:/" for Win32), the
# server will use that explicit path.  If the filenames do *not* begin
# with "/", the value of ServerRoot is prepended -- so "logs/access_log"
# with ServerRoot set to "/usr/local/apache2" will be interpreted by the
# server as "/usr/local/apache2/logs/access_log", whereas "/logs/access_log" 
# will be interpreted as '/logs/access_log'.
#
# NOTE: Where filenames are specified, you must use forward slashes
# instead of backslashes (e.g., "c:/apache" instead of "c:\apache").
# If a drive letter is omitted, the drive on which httpd.exe is located
# will be used by default.  It is recommended that you always supply
# an explicit drive letter in absolute paths to avoid confusion.

#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# Do not add a slash at the end of the directory path.  If you point
# ServerRoot at a non-local disk, be sure to specify a local disk on the
# Mutex directive, if file-based mutexes are used.  If you wish to share the
# same ServerRoot for multiple httpd daemons, you will need to change at
# least PidFile.
#

Define SRVROOT "D:/Server_Apps/Apache24"
ServerRoot "${SRVROOT}"

#
# Mutex: Allows you to set the mutex mechanism and mutex file directory
# for individual mutexes, or change the global defaults
#
# Uncomment and change the directory if mutexes are file-based and the default
# mutex file directory is not on a local disk or is not appropriate for some
# other reason.
#
# Mutex default:logs

#
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the <VirtualHost>
# directive.
#
# Change this to Listen on specific IP addresses as shown below to 
# prevent Apache from glomming onto all bound IP addresses.
#
#Listen 12.34.56.78:80

Thanks! I do notice some differences already. If you browse to "myserver.me/", openrem opens, correct? I'm hosting various sites, so my webroot serves an index, linking to all my applications. Openrem starts when browsing to "myserver.me/openrem".
you: WSGIScriptAlias /
me: WSGIScriptAlias /openrem

[Ed McDonagh]

Some of this confusion comes from the following history:

• Originally, it was necessary to go to /openrem in order to view the site. /admin links were at the root, but everything else required /openrem including the homepage. I didn't like this, too unfriendly.
• Issue #171 that relates to this was fixed in commit 7c0ff72bbf07 by adding the initial r'^' match referring to remapp.urls. This meant that you could go to the root URL and expect the site to be displayed.
• However, the templates had lots of /openrem/stuff links in, which meant that in effect you only ever dropped the /openrem part of the URL for the first page.

This means that where we have absolute URLs that start with /openrem they are resolved on your system by chance almost, as they are actually being interpreted as being /ct/ for example when you go to /openrem/ct/. So that the site works on your server at all is by chance.

I guess what we need is some sort of variable declaring the root URL after the domain name, and having it prefixing all the URLs in the template. Otherwise we need to use relative URLs, which then makes the templates more difficult as they all build on each other, and with absolute URLs it doesn't matter where in the site hierarchy the URL is surfaced.

Glad to be of help. Yes, on my install OpenREM is at myserver.me/.

However, myserver.me/openrem/ also works for me (and everyone else's OpenREM install) due to the contents of urls.py in the openrem\openremproject folder (see the contents of that file below). This redirects both myserver.me/ and myserver.me/openrem to the same set of pages. I think this was put in so that users didn't have to use the "openrem" bit of the address.

If I comment out the "url(r'^', include('remapp.urls'))," line and restart Apache then myserver.me/ no longer takes me to OpenREM, and I have to use myserver.me/openrem/. Maybe commenting out this line will work for you?

from django.conf.urls import patterns, include, url

# Uncomment the next two lines to enable the admin:
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    url(r'^', include('remapp.urls')),
    url(r'^openrem/', include('remapp.urls')),
    url(r'^admin/', include(admin.site.urls)),
    # Login / logout.
    url(r'^login/$', 'django.contrib.auth.views.login'),
    url(r'^logout/$', 'remapp.views.logout_page'),

)

I think if you do as @dplatten has suggested, you will have to go to myserver.me/openrem/openrem to see content. I would be interested if this is the case.

I restored all code and configurations to their original versions and tried David's suggestion. This unfortunately broke my main site (gave me a django error). Temporarily did solve my trailing slash problem though ;) I would very much prefer openrem (including admin, login, logout links) to stay within a subfolder, in order to prevent conflicts with other applications. Messing around with the apache config and urls.py file might still be the solution. I'll keep trying other configs.

My current config is as follows:

/etc/apache2/sites-enabled/mysite.conf

<VirtualHost *:80>
        ServerName mysite
        ServerAdmin webmaster@localhost
        DocumentRoot /var/www/mysite
        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

        # enable python cgi-scripts
        <Directory "/var/www/mysite">
           AddHandler cgi-script .py
           Options +ExecCGI
        </Directory>

/etc/apache2/apache2.conf (includes above file)

# This is the main Apache server configuration file.  It contains the
# configuration directives that give the server its instructions.
# See http://httpd.apache.org/docs/2.4/ for detailed information about
# the directives and /usr/share/doc/apache2/README.Debian about Debian specific
# hints.
#
#
# Summary of how the Apache 2 configuration works in Debian:
# The Apache 2 web server configuration in Debian is quite different to
# upstream's suggested way to configure the web server. This is because Debian's
# default Apache2 installation attempts to make adding and removing modules,
# virtual hosts, and extra configuration directives as flexible as possible, in
# order to make automating the changes and administering the server as easy as
# possible.

# It is split into several files forming the configuration hierarchy outlined
# below, all located in the /etc/apache2/ directory:
#
#       /etc/apache2/
#       |-- apache2.conf
#       |       `--  ports.conf
#       |-- mods-enabled
#       |       |-- *.load
#       |       `-- *.conf
#       |-- conf-enabled
#       |       `-- *.conf
#       `-- sites-enabled
#               `-- *.conf
#
#
# * apache2.conf is the main configuration file (this file). It puts the pieces
#   together by including all remaining configuration files when starting up the
#   web server.
#
# * ports.conf is always included from the main configuration file. It is
#   supposed to determine listening ports for incoming connections which can be
#   customized anytime.
#
# * Configuration files in the mods-enabled/, conf-enabled/ and sites-enabled/
#   directories contain particular configuration snippets which manage modules,
#   global configuration fragments, or virtual host configurations,
#   respectively.
#
#   They are activated by symlinking available configuration files from their
#   respective *-available/ counterparts. These should be managed by using our
#   helpers a2enmod/a2dismod, a2ensite/a2dissite and a2enconf/a2disconf. See
#   their respective man pages for detailed information.
#
# * The binary is called apache2. Due to the use of environment variables, in
#   the default configuration, apache2 needs to be started/stopped with
#   /etc/init.d/apache2 or apache2ctl. Calling /usr/bin/apache2 directly will not
#   work with the default configuration.


# Global configuration

# ErrorLog: The location of the error log file.
# If you do not specify an ErrorLog directive within a <VirtualHost>

Hi @tcdewit did you resolve this? I think Ben Earner has the same problem on the Google group: https://groups.google.com/d/topic/openrem/jZqhjCSUlGM/discussion

[Tim de Wit]

After several mods and hacks I finally gave up and hosted a new virtual domain on my server, dedicated for openrem; no problems since then...

[Ben Earner]

I was just reading over the change log for 0.9.0b, is this issue duplicated/resolved by #667? I'm going to test it (I haven't updated yet) but this issue might be able to be closed.

[Ed McDonagh]

Thanks Ben. Yes, you're right. I'll add it to the change notes later :)

[Ed McDonagh]

Updating changes with ref #667 which fixes #461. [skip ci] docs only
