Using Params hash in my Rails App

So what I am trying to do is generate a list of breweries based on a location that the user enters into an input field. How I have it set up is in my javascript I have the browser send ajax requests to the server, the server then communicates with a 3rd party's database and back to the browser.

This code works when I hardcode a location like "Chicago" in the controller but I want to generalize it so I can pass in whatever location the user inputted. I think this has something to do with the params hash but am uncertain as to how to implement.

routes.rb

get 'search' => 'home#search_breweries_by_location'

home controller.rb

def search_breweries_by_location
  breweries = @brewery_db.locations.all(locality: location)
  render({:json=>breweries})
end

/home/index.html.erb

var location = document.getElementById('location').value;

$.post('/search', {locality: location}, function(data){
  for(var i = 0; i < data.length; i++){
    $('#brewery-list').append(data[i].brewery.name);
  }
});

One of your issues is that you are making a POST to /search but you only have a route that matches GET on /search. I would start by switching your route to match on POST instead of GET.

I'm sort of new to Rails myself, but I've always used the following paradigm to look things up in ActiveRecord:

@brewery_db.locations.where(locality: params[:locality])

Again not sure if this solves your issue, but maybe the params[:locality] part will get you what you need.
