Question

I am using Rails to develop a project.I want to change this url

http://my_domain/users/1

to

http://my_domain/users/Tom

The 1 is id,and the Tom is name in the database.

How to realize it?

Answer 1

In the controller:

def to_param
  “#{name}”
end

Now you can find users by

@users = User.find_by_name(params[:id])

In the view:

<% @users.each do |user| %>
...
<%= link_to "Detail", user_path(user.name) %>
<% end %>

I hope this can help you.
