Hi Alfredo,
the error is that the `user` variable doesn't exist, maybe you mean `@user`?
You can try without the user variable and it should work:
<%= button_to 'Add Photo' , home_add_path(user_id: 1) %>
About how to call a method from a view (which is a different question),
just call it:
<% method_name %>
The method must be in the right scope. As an example you can call methods
defined in the helper files.
If you define instance variables (variables starting with @) in the
controller, you can use them from the relative view (and call their public
methods):
class UsersController < ApplicationController
def index
@user = User.first
end
end
# app/views/users/index.html.erb
User name: <%= @user.full_name %>
ok?
