Hi, after saying this you will hate me, but i’ve changed an url which
takes not the id but the nick. Something like /users/mix/comments
everything works fine, just for a “little” problem, when i create the
link with link_to or the paginate method it lowercase the controller
string, so if i pass it something like :controller =>
“/users/#{@user.nick}/comments”, :action => :index it will lowercase the
nick, and if the nick is eg MiX it won’t find any user with mix.
How can i solve this with have the nick as is? with link_to it can be
solved without pass {:controller… } but
“/users/#{@user.nick}/comments”, it works, but the problem stays with
the paginate url, it doesn’t accept that
Or another solution would be accept any kind of nick case insensitive,
but i think that this would charge more the search in the db, and anyway
it’s better to show the nick as the user has written it
Thanks
It shouldn’t be case-sensitive.
User.find_by_username(params[:user_id]) should return the user.

the problem is that find_by_username is case sensitive, if i’ve a user
“Mix”, if i find_by_username(‘mix’) it won’t be found
I know this isn’t exactly what you want, but I find it a nice go
between often times, and you don’t need to hack everything up to make
it work.
I would pass the id as well as the username. You can do that by
setting the method to_param in the model file for whatever model you
want to preform this on, in your case, the user model.
user.rb
def to_param
“#{id}-#{username}”
end
The cool thing about to_param, is that you don’t have to change any of
your link_to methods, or .find methods normally.
If you did this in the view:
index.rhtml
link_to @user.username, {:action => “show”, :id => @user}
or if you are using restful routes:
link_to @user.username, user_path(@user)
Looks pretty normal right? The cool thing is that even though it
looks that normal, when you hit the link in the browser, the url will
look like this:
“/users/12-billybob”
And in your controllers, you can do a very basic:
User.find(params[:id])
If you still want to use only the username, there are also ways to do
that, but they are not as easy, lemme know.

Why are you doing this:
:controller => “/users/#{@user.nick}/comments”,
:action => :index
I don’t understand… you have a controller (or namespace) named for
each user!? I suspect that’s just an error in your question…
I’m surprised that it would be changing the case of your user.nick, but
if there is in fact a problem with that, you could write your own
find_by_insensitive_nick method to work around that.
Have you tried using to_param for this?
class User
def to_param
nick
end
end
Then, if you’re using map.resources for the route:
<%= link_to user_comments_path(@user) %>
Or else:
<%= link_to :controller => ‘comments’, :user_id => @user, :action =>
‘index’ %>

Yep, i need to have just the username without the id

Because i’ve it to show all the comments the user have written, then
i’ve a /comments/id to show just that comment and a /product/id/comments
to show all the product’s comments. I think it’s quite strange

Sorry the ignorance, but how can i search with a case insensitive? and
with, is it possible that the performances will be lower, right ?

yes, but doesn’t work
If you use MySQL you can simply set the collation of the username
field to utf8_general_ci (ci = case insensitive) for the same result.
Solved, i simply use ferret, i’ve done a find_by_username which use
ferret with an insensitive case search, and return the result.
Everything now works perfectly
