I am trying to create a like and dislike function inside rails for that I
am using lin_to helper to pass params but there is an issue when ever
someone tries to copy paste the links it updated the database . I am using
ajax to make this function work here is the code for my method .
Controller code :
class FeedLikesController < ApplicationController
before_action :authenticate_user! ,only: [:create, :destroy]
before_action :get_feed ,only: [:create, :destroy]
def index
@fees = FeedLike.all
respond_to do |format|
format.html
format.js
end
end
def update
@feed_likes = FeedLike.find_or_create_by(feed_like_params)
respond_to do |format|
if @feed_likes.save
format.html { redirect_to root_url, notice: 'Like ' }
else
end
end
end
def create
@feed_like_counter= Feed.find(params[:feed_id])
@feed_likes = FeedLike.find_or_create_by(:feed_id =>
params[:feed_id],:user_id =>params[:user_id])
@f = @feed_like_counter.like_count
@feed_like_counter.like_count = @f+1
@feed_like_counter.save
respond_to do |format|
if @feed_likes.save
format.html { redirect_to root_url, notice: 'Like ' }
format.js
else
end
end
end
def delete
end
def destroy
@feed_like_counter= Feed.find(params[:feed_id])
@feed_likes = FeedLike.where(feed_like_params)
@f = @feed_like_counter.like_count
@feed_like_counter.like_count = @f-1
@feed_like_counter.save
respond_to do |format|
if @feed_likes.destroy_all
format.html { redirect_to root_url, notice: 'Unlike ' }
format.js
else
end
end
end
def feed_like_params
params.permit(:user_id, :feed_id)
#params[:market_place]
end
def get_feed
@feed= Feed.find(params[:feed_id])
end
end
And in views my link is like this :
<div class="feed-like-<%= @feed %> " >
<%= link_to "like",{ :action => 'create', :controller =>
'feed_likes', :feed_id => @feed, :user_id => current_user.id, :remote => true
}, method: :post,class: "btn btn-primary" %>
</div>
And dislike link is like this :
<div class="feed-like-<%= @feed %> " >
<%= link_to "Dislike",{ :action => 'destroy', :controller =>
'feed_likes', :feed_id => @feed, :user_id => current_user.id, :remote => true
}, class: "btn btn-primary" %>
</div>
And my routes is like :
get "/feed_likes/:feed_id/feed_likes/:user_id" => "feed_likes#destroy"
post "/feed_likes/:feed_id/feed_likes/:user_id" => "feed_likes#create"
Here the issue is whenever someone wants to like the feed when I passes the
url direclty it updated the database how can I restrict this only when user
click the button only then it update the database not by url :
There is another issue with this I am using ajax onclick event it updated
the database but when I click the like button fast it update the databse 2
or 3 times before the dislike partial appear . Is there any way I can use
this .
