Hi Nilay,
Ruby and Rails are changing all the time, so it's always useful to post
which versions you are using, if I missed it in your post I apologise.

In which case I would suggest following a few Rails tutorials. A quick
google for 'Rails Tutorials' is a good starting point. You will end up
getting more done, faster, if you take the time out to follow one or two of
those.
You should also have a decent understanding of Ruby and MVC frameworks.
That said, I'll assume the following and try to help.
You have a model: Feed
And a model: FeedLike
Feed has_many :feed_likes
FeedLike belongs_to :feed
Your create action could be as simple as follows:
def create
@feed_like = FeedLike.find_or_create_by(:feed_id =>
params[:feed_id],:user_id
=>params[:user_id])
@feed_like.increment
respond_to do |format|
if @feed_like.save
...
end
end
end
Then, in your FeedLike model you could add the following method:
def increment
self.feed.like_count ++
end
(If you have your models set up correctly then the increment method should
be fine because rails will create the feed method on the FeedLike model,
which points to the Feed model. This then gives you access to the
like_count method of the Feed model.)
Your destroy method could be as follows:
def destroy
@feed_like = FeedLike.where(feed_like_params)
@feed_like.decrement
respond_to do |format|
if @feed_like.destroy
...
end
end
end
(I'm not sure why you're calling destroy_all)
Then in your FeedLike model:
def decrement
self.feed.like_count --
self.feed.save
end
You need to call save here, because calling destroy on the FeedLike model
won't automatically save the Feed model relation.
Personally I would set this all up to go through the Feed controller, which
would also make your links and routes easier to set up.

Probably not the way you have set your routes up. Where did you get the
information from to create them as you have?
You don't seem to be doing anything out of the ordinary to need such custom
routes for your create and destroy methods, so, if you use the following
method for your controller routes you will get the standard routes that you
should be working with.
In routes.rb
resources :feed_likes
What you will need to do, is to pass the feed_id and the user_id as
parameters on your links rather than coding them into the route as you
have. You can also tidy up your links using the routes helper methods such
new_feed_like.
Run 'rake routes' from the command line to see what your routes look like
and what helpers are available.

Fix your routes, then see if this is still a problem.
Obviously all the above is untested, and it's getting late here, so
hopefully I've helped you on the right path.
