16,295 PointsI can not link to profile page
I was building my own web app with ruby and followed build simple app course. At the end I got really stuck by how do you link to the profile page of a current user after changing the routes and urls that match their profile name. I checked my routes and I have profiles_show_ path which I tried and it did not work. I also see in my routes get /:id(.:format) and that was the changed route that would match profile_name of the user and generate their profile by having localhost:3000/cleo where cleo is the profile name. How do I link to it from application.html.erb?

Here's my setup:
get 'users/:id', to: 'users#show', as: :profile
Notice here I have 'users/:id' instead of ':id'. Reason for this is I want to avoid routing errors with any of my pages on my site being looked up as profile_names. If a user happens to pick a profile name "help" and you routed your help pages to "/help", then they could never get to their profile page. Of course, this is a silly profile_name, but you can't really prevent that (you'd have to forbid profile names of specific words and that just gets annoying).
In my user model
def to_param
profile_name
end
Then in my application.html.erb
link_to "My Profile", profile_path(current_user)
Notice if you pass in the current_user in total (the object), rails will automatically know the to_param was set to profile_name and you're set.
You can also do:
link_to "My Profile", profile_path(current_user.profile_name)
Nonetheless, you need to pass in the user whose profile you want to see.

16,295 PointsThank you, Brandon! I added into my routes get '/:id', to: 'profiles#show', as: :profile and in my application.html.erb I added <%= link_to "My Profile", profile_path(current_user.profile_name) %> and it works!!! I will take into consideration your advice about routing errors if users create a name like help.
