Rails Ajax Call : Pass JSON to separate controller method - ruby-on-rails

Question

Hey everyone I am having an issue setting up my app. It uses the shopify API and essentially what it does is grab some data via a view and sends it to the controller but I am having issues passing it to another method in the controller to use the API to save the data.
Here is my code :
Controller
class BuilderController < ShopifyApp::AuthenticatedController
def index
urlval = request.fullpath
#urlCheck = urlval.split('/').last
end
def show
url = request.fullpath
#urlID = url.split('/').last
#customers = ShopifyAPI::Customer.search(query: "id:"+ #urlID)
#need to get a way to retrieve the ajax call info here to pass into the update
end
def updateCustomer(notes)
#customers.each do |cus|
cus.note = notes
cus.save()
end
end
def new
notes = params[:notes]
updateCustomer(notes)
render json: notes
end
end
View
<button id="test">TEST</button>
<script>
var butt = document.getElementById('test');
butt.addEventListener("click",function(){
$.ajax({
url: "/builder/new",
type: "GET",
data: {
"notes": [
"test",
"test2"
]
},
success: function(data,text,xhr) {
console.log(text);
console.log(xhr);
console.log(data);
alert('successfully');
},
error: function(data,error){
console.log(data);
console.log(error);
alert("help");
}
});
});
</script>

Answer 1

Rather than a fully separate method, have you looked into the
respond_to method? http://api.rubyonrails.org/classes/ActionController/MimeResponds.html#method-i-respond_to
You could do (assuming html is the primary request type, change if it isn't):
def index
respond_to do |format|
format.html { actions }
format.json { actions }
end
end
This the method we use to accommodate different request types within the same action. Please let me know if I've misinterpreted your question.

Answer 2

you can use this
update_all(updates) public
Updates all records with details given if
they match a set of conditions supplied, limits and order can also be
supplied. This method constructs a single SQL UPDATE statement and
sends it straight to the database. It does not instantiate the
involved models and it does not trigger Active Record callbacks or
validations.
http://apidock.com/rails/v4.0.2/ActiveRecord/Relation/update_all
def new
notes = params[:notes]
#customer.update_all({note: notes})
respond_to do |format|
format.html {}
format.json { json: #customer.json }
end
end
