Hey guys I'm completely lost at this point I'm trying to make a simple app that takes an input in the form of a string ("City, State") and sends that string to the google_places gem to do spot_by_query("gas station near #{enter value from input}")

Then I need the 1st 10 results and be able to print out their names.  I have become completely lost in my attempts and was looking for some advice. 

Here is my controller

class LocationsController < ApplicationController

  before_action :set_location, only: [:show, :edit, :update, :destroy]

  # GET /locations

  # GET /locations.json

  def index

    @location = Location.new

  end

  # GET /locations/1

  # GET /locations/1.json

  def show

  end

  # GET /locations/new

  def new

  end

  # POST /locations

  # POST /locations.json

  def create

    @client = GooglePlaces::Client.new('################')

    @shops = @client.spots_by_query('coffee near #{@location(params[:address])}')

    @result = JSON.parse(@shops[1])

    # @location.find_closest_shops(@location.params[:address])

  end

  private

    # Never trust parameters from the scary internet, only allow the white list through.

    def location_params

      params.require(:location).permit(:address)

    end

end

Here is the input form

<%= form_for @location do |f| %>

  <%= f.label :address %>

  <%= f.text_field :address, :placeholder => "City State" %>

  <br>

  <%= f.submit "Find Coffee!" %>

<% end %>

Here is the output form (this is where I'm lost)

<%= print "#{@result['name']}" %>

Well, after making a few assumptions:

• you are going to a URL that gets routed to the index action like /locations
• the form posts to /locations

In your create action, you probably need to replace:

    @shops = @client.spots_by_query('coffee near #{@location(params[:address])}')

With:

    @shops = @client.spots_by_query("coffee near #{location_params[:location][:address])}")

Noting that you won't have an @location set (it will be nil because all instance variables are nil by default).

You need to actually get the params which will look something like: { location: { address: "entered value" } }

You can probably see this in the development.log.

In Ruby, single-quoted strings do not do interpolation. Thus:

here = "Cincinnati"

puts 'coffee near #{here}'

coffee near #{here}

but:

puts "coffee near #{here}"

coffee near Cincinnati

so that should get you going again.
