Data always empty AJAX call Rails 5

To fix the issue you can do 1) Have you checked the params[:term] actually contains the string you enter ? For example by adding a binding.pry at the beginning of your index method in your controller, and checking in terminal console what's the value of params[:term] when the code is stopped by binding.pry?
2) What is your search_beer method? Have you tried definining a pg search scope in your Beer model, as explained here:https://github.com/Casecommons/pg_search#user-content-pg_search_scope ? Then you could have a search_by_name method (if your Beer model has a name attribute) so that Beer.search_by_name(params[:term])returns an array of beers whose name match what you have in params[:term]

Does that help In order for Cake to populate the $this->data variable, the data being send needs to follow the format data[Model][field], or at least be part of the data[..] array. If it's plainly named arr, Cake won't put it in the $this->data variable.

this one helps. Your code seems OK. Please double check your URL. Hit your URL from browser to see response. This issue is only because of your PATH.

Ajax Call Thinks That Data Contains [ ]'s when it should be empty

like below fixes the issue You are returning the result of ToList(), which is always a new List(); it is never null. This then gets serlialised to a string by your GetPosts action and returned to your JS code as [].
Even if you returned null from the action, the error handler in your AJAX code would not be hit as a 200 status code would be returned. error only fires if something other than 200 is returned.
