Im struggling to make my Like links to work with ajax. After clicking on "Like" nothing changes, only after refreshing the page I can see that like got counted.
EDIT: Addet routes. EDIT2: I inspected the Like link with Firebug and after entering the code from like.js.erb file it shows message: Image My like.js.erb file:
<% if Like.find_by(likeable: @post) %>
$(".likes").html("<%= escape_javascript(render 'posts/unlike' ) %>");
<% else %>
$(".likes").html("<%= escape_javascript(render 'posts/like' ) %>");
<% end %>
(I have checked and If conditions works fine). My partial for posts (_post.html.erb).
<li class="post">
<span class="user"><%= link_to post.user.name, post.user %></span>
<br>
<span class="title"><%= post.title %></span>
<br>
<span class="ava"><%= image_tag post.avatar(:large) %></span>
<br>
<span class="timestamp">
Posted <%= time_ago_in_words(post.created_at) %> ago.
<% if logged_in? && current_user.admin? %>
<%= link_to "delete", post, method: :delete,
data: { confirm: "You sure?" } %>
<% end %>
################## START OF THE LIKES #####################
<span class="likes">
<span class="like">
<% if logged_in? %>
<% if !current_user.likes?(current_user, post) %>
<%= render 'posts/like', post: post %>
<!-- <%= link_to "Like", like_post_path(post, like: true), method: 'post', remote: true %> -->
</span>
<% else %>
<span class="unlike">
<%= render 'posts/unlike', post: post %>
<!-- <%= link_to "Unlike", like_post_path(post, like: false), method: 'post', remote: true %>-->
</span>
<% end %>
(<%= pluralize( post.likes.size, "like") %>)
<% else %>
<%= link_to "Like", login_path,
data: { confirm: "You need to log in to like" } %>
(<%= pluralize( post.likes.size, "like") %>)
<% end %>
</span>
################## THE END OF THE LIKES #####################
</span>
</li>
And the like method in the post controller.
def like
post = Post.find(params[:id])
if Like.find_by(likeable: post)
Like.find_by(likeable: post).destroy
respond_to do |format|
format.html do
flash[:success] = "Like Updated!"
redirect_to :back
end
format.js
end
else
Like.create(likeable: post, user: current_user, like: params[:like])
respond_to do |format|
format.html do
flash[:success] = "Like Updated!"
redirect_to :back
end
format.js
end
end
end
And Like and Unlike partials I use: Like:
<%= link_to "Like", like_post_path(post, like: true), method: 'post', remote: true %>
Unlike:
<%= link_to "Like", like_post_path(post, like: false), method: 'post', remote: true %>
Any help or advice would be nice. I know that my code is rather in bad condition so don't be afraid to suggest some changes in it. And finally Please help me, I have wasted tons of time on trying to make it work but no results yet.

There are logs after I click on Like.
