There is not enough data in your question but ill try to help you.

Your client-side logic should look like that (jQuery code):

$("#some_button").bind("click", function(event){
    $.ajax({
        type: "POST",
        url: "/bla-bla/create",
        data: { my_param: JSON.stringify(my_data) }
    });
});

And action of controller that match to route /bla-bla/create:

def create
    my_var = JSON.parse(params[:my_param])
    ... 
    #do what you want with "my_var"

Hope it'll help you!

SO you need to know the format of incoming data. But the main principle is that you should parse incoming parameter which contains string representation of your json. – Parandroid May 27 '13 at 11:27
i felt that your def creat code is fine,but i need some clarity,i am parsing from my client side "content", – Jitendra Patidar May 27 '13 at 11:29
could you clearly mention what i want to do in post method in def create function – Jitendra Patidar May 27 '13 at 11:34
http://pastebin.com/e0axwZiC see this link,what are the changes i want to do in def create function for post method – Jitendra Patidar May 27 '13 at 11:36
If your Post is Rails resource ("resources :posts" in routes.rb) then your create action already matches POST method. Maybe you want allow 2 types of creating posts - one from your app and one from json, coming from android app. Is it close to reality? – Parandroid May 27 '13 at 12:00
