    Hi

I am newbie to cherrypy. I am using cherrypy 2.2.0 beta. I am having problem while i run the application in the production mode.

I have the configuration file to set the environment. The file contains the following lines of code.


============================================================
webgui.conf
============================================================

[global]
server.environment: "production";
server.log_to_screen
 = True
server.log_tracebacks = True
server.thread_pool: 1
session_filter.on = True
error_page.404 = "/app/www/404.html"
server.socket_host = "0.0.0.0"
server.socket_port:
 80
server.reverse_dns: False
static_filter.root = "/app/www"

[/static]
static_filter.on = True
static_filter.dir = "static"
=================================================================


I have a file named webgui and started the cherrypy server like this

===============================================================
webgui
===============================================================


Class App():
    _cp_filters = [ httpauthfilter.HttpAuthFilter(realm="MyApp",
           ;         privateKey="myapp", unauthorizedPath="/unauthorized",
           ;         retrieveUsersFunc=retrieveAuthUsers)]



   
    cherrypy.expose
 ;   def index(self):
       ; import index
        return index.Render()


os.chdir('/app/bin';)
cherrypy.root = App()
cherrypy.config.update(file='
webgui.conf')
cherrypy.server.start()
================================================================

I have unauthorized.kid file. It just print the login failure error message
========================================================


<html&gt;
<head>
<title>ERROR: Login failed</title>
</head&gt;
<body bgcolor=&quot;#ffc0cb">
<h1>ERROR: Login failure, access denied</h1>
<;p>Login failure, please provide correct administrator username and password

to access this web page.</p>
</body>
&lt;/html>

========================================================

while i run that application , I got the following error
================================================================

&nbsp;File "/usr/local/lib/python2.4/site-packages/kid/__init__.py";, line 112, in load_template
 &nbsp;  raise Exception, "Template not found: %s (in %s)" % (
Exception: Template not found: unauthorized.kid
 (in /, /)
================================================================

If i run the same apllication in development mode. Its works fine.

If anything i missed in the conf file. please help me anyone.


Thanks in advance.

Hmm, that sounds strange.  It certainly seems like a path
issue, but I
can't explain why it would work in development mode but not
in
production mode.  One thing you might try is specifying
absolute paths
to whatever you are using to render your Kid templates. 
Using a
relative path is probably causing the problem.

HTH,

  Thanks christian.

 I have used called the template like this in my index.py
.
====================================================
Index.kid
====================================================
&nbsp;page = kid.Template('Index.kid', args=args)
 return page.serialize()

============================================

If i used the absolute path like this
page = kid.Template('/app/bin/Index.kid', args=args)

Its working fine in production environment.

I need like this

rootdir = '/app/bin/"

kid.Template( rootdir + 'Index.kid', args=args)

I have 20 or more kid files. I have to use the rootdir globally. Tomorrow if i want to change some other path. I can change only the rootdir value. I don't want to go all the kid files and changed.


where i have to define the variable, In my webgui or conf file.

Is there any predefined variable in cherrypy.?

please give me some example links.

Well, you can set it as a "constant" in some .py
file and import it
where you setup your templates.

# settings.py
ROOTDIR = '/app/bin'

# somefile.py
import settings
import os
...
...
kid.Template(os.path.join(settings.ROOTDIR, 'Index.kid'),
args=args)

-----------
You could also stick it in your app's config file in a
special section
for your app and then get at it in the following manner:

# app.conf
[local_settings]
rootdir = '/app/bin'

# somefile.py
rootdir =
cherrypy.config.configs['local_settings']['rootdir']
kid.Template(os.path.join(rootdir, 'Index.kid'), args=args)

-------------
Either of those methods should work - pick the one that you
like best.

Good luck,

Christian

Christian i tried both methods. Once again i have problem. If i run in development mode. Its working fine.


Once i changed my environment as production mode. And then run my application and clear my browser cookies and cache everything. I got an following error from my browser.
==================================================================


500 Internal error
        
The server encountered an unexpected condition which prevented it from fulfilling the request.
=====================================================================

If i clears my browser cookies and cache , I got the above error. Even i have my 
Index.pyc file. 

I don't know what is going on. Almost i complete my site in development environment, If i change into production environment . I got problem.

Cherrypy is my best framework. This problem makes me uncomfortable. I am googling and study cherrypy receipes also. I can't able to solve these issue. 


Is there anything mistake from my application or its a cherrypy problem.

Please help me to solve the issue.

Hi,

Could you paste a better traceback if you have one when you
run into the
problem in production mode?

Thanks,

    Hi

Christian thanks a lot.

Accidentally i got the solution. Now i have no problem in production mode. That day itself i tried your both methods. Its not working. Suddenly I tried that again using this following method.

==================================================================
# settings.py
ROOTDIR = '/app/bin'

# somefile.py
import settings
import os

...
...
kid.Template(os.path.join(settings.ROOTDIR, 'Index.kid'), args=args)
===================================================================

Cherrypy rocks.

Thank you very much.
