Is there a way to stop Rails automatically trying to load models? Cheers, Nicholas
By loading, do you mean accessing the model''s class on boot up? Retrieving database rows? Nicholas Henry wrote:> Is there a way to stop Rails automatically trying to load models? > > Cheers, > Nicholas-- Posted via http://www.ruby-forum.com/.
Alex, I want to stop the automatically requiring/loading of models when I am calling it from a controller e.g. No such file to load -- user.rb as my actual models are outside of the model directory. (it''s a long complicated story ;) ) I don''t want rails to do this at all, as I want to have have the control of doing the require.

I don''t know how to disable it, but you might want to take a look at the ''Sharing Models between Applications'' recipe in Chad Fowler''s book. Most of the methods mentioned either make copies of the model files in the right place, or tell the OS to look for them elsewhere.

Thanks Kevin: In this case it''s a matter of not sharing models, but having control of what models are required/loaded.

The question is, is Rails smart enough to not load a model if defined?(User) I''m thinking that have a class of User already should prevent Rails from loading a file to find it. Totally untested solution but there is a chance it might work :) -- Posted via http://www.ruby-forum.com/.
Thanks, Alex, unfortunately Rails still trys to require/load even if the Class/Model is already avaliable.

Hi Nicholas,
your statement that rails "still tries to require/load even if the
Class/Model is already available" doesn''t make sense.
Rails only auto-loads your models as part of a const_missing hook -
which means that from ruby''s perspective, the constant you are trying
to use doesn''t (yet) exist.
You can try this for yourself:
in models/wibble.rb
class Wibble
puts "#{self.name} loaded"
end
Then run ./script console and type:
Wibble
it should print out "Wibble loaded"
quit from the console and run ./script/console again, typing this:
class Wibble
end
Wibble
it should *not* print out "Wibble loaded"
As in, Wibble has already been defined so there''s no need to go
looking for (and load) a wibble.rb file...
You might need to post more complete information to diagnose what''s
actually going on.
