Rails - Apr 2007 - REST with :name as unique identifier, rather than :id

Hi all,

Is it possible to implement REST with :name as a unique identifier of
a model, instead of the :id? Having readable (literally) URLs is
important to my application as many URLs are announced at conferences
or read out over the phone.

For example, I''d like to do:

/branches
/branches/bristol
/branches/bristol;edit

Cheers,

Tom

In your controller, you just need to replace:

Branch.find(params[:id])

with:

Branch.find_by_name(params[:id])

and then possibly add to your Branch model:

class Branch
   def to_param
     self.name
   end
end

so URL generation will do the right thing if you have:

edit_branch_url(@branch)
or
edit_branch_url(:id => @branch)

Thanks Rob,

That''s amazingly simple... Any other gotchas I should be aware of?

Cheers,

Tom
