Hello! I can’t find a way to have rails not use a database. I just  
left my database.yml file as it is. When I run my rails application  
that has no models, my browser says that it couldn’t connect to a  
database. In environment.rb I uncommented the line  
config.frameworks -=  
[:active\_record, :active\_resource, :action\_mailer]  
but then Webrick won’t start. Sorry if this has already been posted or  
the solution is really simple, I couldn’t find anything after about a  
half hour of searching and I’ve only been using rails for a few days.  
Thanks!

That is about it but you need to also remove any other reference to  
those frameworks (eg in the config files or in the initializers)

Thanks for responding! Since I am new to rails, could you tell me  
where the references are in the config files or initializers that I  
should remove? I didn’t add any references myself. Also, I don’t  
really need to get rid of active resource or action mailer, but I am  
unsure if it is necessary. If I changed the line to  
config.frameworks -= [:active\_record]  
would it be easier to remove active record or do active resource and  
action mailer rely on it?

Anything that mentions any of the frameworks you are disabling, eg  
there are some that setup actionmailer.
