I have a Cart controller and a "show" view which shows the contents of the cart. I want to show the cart in every view of my Products controller. So, I'm rendering the cart/show in products/show using
<%= render "/cart/show" %>
Now, I want to update the cart via ajax when a user wants to add a product. Please guide me how I should design my controllers to achieve this.
How to use partials to DRY up your views. http://guides.rubyonrails.org/layouts_and_rendering.html
function postToRailsApi() {
$.ajax({
type: "POST",
url: "the_url_you_want_to_post_to/endpoint",
data: {someData: {thisId: otherId}},
dataType: "json",
success: function(data) {
alert("OMG SUCCESS status:200")
}
});
In the rails controller:
respond_to do |format|
if @my_condition.save
format.html {render nothing: true, status:200}
format.js{render nothing: true, status:200}
format.json { render json: @timestamp, status: 200 }
else
format.html { render action: "new" }
format.js { render nothing: true, status: 400 }
format.json { render nothing: true, status: 400 }
end
end
Obviously your logic will be different.
