I built my rails app locally, and just today put it all online.

Getting a “Application error (Rails)” when trying to submit some form  
parameters to the db.

What needs to be done with going from local development to live?

I’m not sure if/where I need to set my app to “production” status.

Also, is there any way to debug “Application error (Rails)”??

Thanks,  
stirman

Look in the log files. It should tell you what the error is. If you  
are seeing that messge you are in production mode, so look in  
log/production.log. The environment is set via variable passed from the  
webserver config, or from config/evironment.rb. You should see a  
commented few lines in there:

# Uncomment below to force Rails into production mode when

# you don’t control web/app server and can’t set it the proper way

# ENV[‘RAILS\_ENV’] ||= ‘production’

That will set it to production mode, although it should ideally be set  
by the web server.

3 possible reasons:

1. Rights Issue. The webserver is unable to write to tmp or log. To  
test this you can type in from the rails root the command “chmod -R  
777 log/ tmp/”. A dirty way to do things but it will at least tell you  
if that was the problem,
2. public/.htaccess points to dispatch.cgi instead of distpatch.fcgi.
3. ruby is in non standard location. Type in the command “which  
ruby”. Compare the ruby location to the one in dispatch.fcgi.
4. rinse and repeat.
