edit
after the last edits I still have a problem....
when I try to go on the account_path I have this error
Last edit
Just to remind you, I am using devise:
As a user logged in, if I want to see my own profile, I use
account_path (and this work well)
The link for visiting a user's profile page looks like this:
= link_to 'View', user_path(user)
but it looks like it point exactly like: account_path. ( So on my profile, not on the user I want to visit)
I am not sure what to use in my controller, if I use #user = User.find(user_params[:id]) || current_user or ##user = User.find(user_params[:id])
I have the following error:
ActionController::ParameterMissing in UsersController#show
param is missing or the value is empty: user
If I use #user = User.find(current_user).
I am redirected on my own profile each time....
def show
#binding.pry
##user = User.find(current_user)
##user = User.find(user_params[:id])
#user = User.find(user_params[:id]) || current_user
#tutos = Tuto.all
end

Answer 1

This will set #user to current user or to requested user for admins
#user = current_user.admin? ? User.find(params[:id]) : current_user

Answer 2

In #show you could something like:
# Assuming params[:id] is the ID of the user's profile you're trying to view
def show
user_id = current_user.admin? ? params[:id] : current_user.id
#user = User.find(user_id)
end

Answer 3

The problem is in your route file remove 'as user do' blocks it makes some bizzare things :
user GET /users/:id(.:format) users#show
GET /tutos/new(.:format) tutos#new
GET /tutos/:id/edit(.:format) tutos#edit
GET /tutos/:id(.:format) tutos#show

Answer 4

Do you want to use the account_path to view another user's profile, or could you go to /users/2 for the user with id of 2? That uses the show action in the controller and routes to the user path using the relevant id?
