[Rails] Re: AJAX vote update for a nested resource
I'm not sure why it still isn't working for me.
<%= pluralize(review.votes_count, 'vote')
%>
create.js.erb
$("review_<%= @review.id %>").html("<%= @review.votes_count %>")
I don't see any errors in the log.

[Rails] Re: AJAX vote update for a nested resource
That's to be expected with your HTML.
What you currently have will generate HTML that looks like the following if
you have 3 reviews:
1 vote
2 votes
3 votes
$("#votes").html("3 votes")
$("#votes").html("4 votes")
$("#votes").html("5 votes")
See the problem?
The problem is that each paragraph tag has the same ID. jQuery will only
update the first one. Each paragraph needs to have a unique ID, then your
JavaScript to update the paragraph needs to update the specific unique ID.
Including the primary key in the HTML ID is a good solution:
Then your jQuery can update the specific paragraph that it needs to:
$("#review_<%= review.id %>").html("<%= review.votes_count %>")

[Rails] Re: AJAX vote update for a nested resource
That doesn't quite work. When I use <%= @review.votes_count %> in the
create.js.erb file it updates the counter on the first review,
regardless of whether the vote was placed on the first review or not.
I thought maybe if I loop through the reviews again the create.js.erb
file it might work.
<% @house.reviews.each do |review| %>
$("#votes").html("<%= review.votes_count %>")
<% end %>
This did not work either.

[Rails] Re: AJAX vote update for a nested resource
You're defining @review as an instance variable, so you have to use it as
one in the view:
$("#votes").html("<%= *@*review.votes_count %>")
