Before I explain my problem, I will provide the relevant code for context. I have a Teams Model which is associated to a Scoreboard Model. The problem at hand is associated with Teams.
The View for Teams Index
<div class="team-list">
<%= render @scoreboard.teams.reject(&:new_record?) %>
</div>
The Partial for @scoreboard.teams
<div class="row team-div" id="team_<%=team.id%>">
<div class="col-xs-3 team-div-1"> <%= team.name %> </div>
<%= link_to (edit_scoreboard_team_path(@scoreboard, team)), remote: true do %>
<div class="col-xs-6 team-data">
<div class="row">
<div class="col-xs-4 team-div-2"><%= team.win %> </div>
<div class="col-xs-4 team-div-2"><%= team.loss %> </div>
<div class="col-xs-4 team-div-2"><%= team.tie %></div>
</div>
</div>
<% end %>
<div class="col-xs-1 team-div-2">
<%= team.win + team.loss + team.tie %>
</div>
<div class="col-xs-1 team-div-2">
<% total_games = team.win.to_i + team.loss.to_i + team.tie.to_i %>
<% if total_games == 0 %>
<%= "N/A" %>
<% else %>
<%= (team.win.to_i/(total_games).to_f*100).round(2) %><%="%"%>
<% end %>
</div>
<div class="col-xs-1 team-setting">
<i class="fa fa-trash-o fa-lg" aria-hidden="true"></i>
</div>
</div>
The link_to I'm having trouble with is for the Edit Method.
Team#edit Controller Method
def edit
@scoreboard = Scoreboard.find(params[:scoreboard_id])
@team = @scoreboard.teams.find(params[:id])
respond_to do |format|
format.html {redirect_to scoreboard_url(@team.scoreboard_id)}
format.js
end
end
The edit.js.erb file
$("#team_<%[email protected]%>").hide();
$("#team_<%[email protected]%>").before("<%= j render 'teamedit'%>");
Now, to explain the problem.I am in the development environment. In a perfect world, I would like to click on the link_to for edit and have the specific team div disappear right away(only so I can't click on it again) and render the edit form for that Team. However, during slow loads(happens a lot), I can click on the link_to two or three times and it calls multiple controller requests to the edit method. The problem with this is that the Jquery is also executed as many times as I clicked and I end up with 2 or 3 forms for the same element.
For example, these are the log files when I click really fast on the link_to for Team with Id=50:
Started GET "/scoreboards/1/teams/50/edit" for 99.239.140.167 at 2016-04-30 08:07:52 +0000

Rendered teams/edit.js.erb (5.6ms)

Each request rendered edit.js.erb so I ended up with two forms. How can I make it possible that no matter how many times I am able to click on the "link_to" before it disappears, only one edit-form for that resource is generated?
You could fix this by disabling the link on first click using jQuery
.
Add a class to the link
<%= link_to (edit_scoreboard_team_path(@scoreboard, team)), remote: true, class: "team-edit-link" do %>
...
<% end %>
Disable the link when it is clicked
$('.team-edit-link').click(function(e) {
if($(this).hasClass('disabled')){
e.preventDefault();
}
else{
$(this).addClass('disabled');
}
});
