Im building sort of a facebook clone, and one of the requirements for the project is being able to "like" posts.

I have the liking down, (im also using devise fwiw on the user authentication). But when I try to flash that a user has already liked a post (since you can't like more than once) nothing happens.

My controller code:

 def like
 post = Post.find(params[:post_id])
 puts post
 like = post.likes.new(user_id: current_user.id)
 if like.save
 #nothing for now
 else
 flash.now[:alert] = "You have already liked that post"
 end
 end

It works by being on a users "homepage" and going through all of their posts and having a "like" option on each one. (Liking does work, but figured it was worth noting).

If I just do flash it'll work if I refresh the page, but currently does nothing right now.

The "Like" link looks like this:

<% @posts.each do |post| %>
<p>
 <%= post.content %>
</p>
<%= link_to "Like", like_path(@user, post_id: post), remote: true, method: :post %>
<% end %>

In rails there is one gem for ajax call flash messages
Toaster gem

Create one method in application_helper.rb

def custom_bootstrap_flash
 flash_messages = []
 flash.each do |type, message|
 type = 'success' if type == 'notice'
 type = 'error' if type == 'alert'
 text = "
 <script>
 $(function () 
 toastr.#type("#message");
 );
 </script>
 "
 flash_messages << text.html_safe if message
 end
 flash_messages.join("n").html_safe
end

Include it in your layout application.html.erb

<%= custom_bootstrap_flash %>

And in your action.js.erb show toast message using toaster method

toastr.success('Success.')
toastr.error('error')

I hope this what you are looking.

The flash method on rails shows only on successful redirect. If you want to show the message on the same page it would be better to show the message using JS.
