Rails：通过链接更新用户

Question

I am trying to update a devise record via a link in my view.

This is what I've have:

= link_to "Update", user_registration_path(current_user, user: {abc: true}), method: :put, remote: true

I get the following issue:

private method `to_param' called for #

How am I able to update this record remotely?

Answer 1

When I try to do this what I do is a create a method that the link resolves to like

routes

resources :users do 
  match "update_abc" => "update_abc#users", :as => :update_abc, via: :get
end

now in your view you can do

users_update_abc_path(current_user, abc: true, efg: 21)

and in the controller

def update_abc
  user = user.find(params[:id])
  if params[:abc].present?
    user.abc = params[:abc]
  end
  ....
  user.save
  redirect_to :back
end

I hope that this helps :)
