ActiveRecord#find needs an id, even when to_param and from_param has an override

[deepak]

Have a ActiveRecord model, which overrides to_param and from_param
but ActiveRecord#find does not use from_param.
to_param needs the id to be appended to it, for AR#find to work

explained at http://apidock.com/rails/ActiveRecord/Base/to_param, by balint_erdi in the comments
example at: https://gist.github.com/3135755

find(123-hello)is equal find(123)because 123-hello  is typecastedto the type of colum in this case the ìd that is an integer, infact "123-hello".to_i == 1234
Anyway this is not a issue, if you have any new proposals you can send an email or post a message to rails core team google group

Yeah, @acapilleri got it right. When using some sort of slug that starts with id, that works out of the box because of typecasting, and find will always receive an id - or array of ids.

from_param does not exist in Active Record, the tip existent in apidock is solely to keep methods in sync in your app, so you have a single finder to use wherever needed, but AR has no knowledge of it.

Thanks!
