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]
#{@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” %>
<%= f.submit “Find Coffee!” %>
<% end %>
Here is the output form (this is where I’m lost)
<%= print “#{@result[‘name’]}” %>
It sounds like you want to write some pseudo-code on the rails console.
Do you know how to use the rails console?
Figure out how to use the Rails console and then execute what yo’ve got
in your create method line-by-line
That should let you poke around the results of the GooglePlaces object
and see how it works. You should be able to replicate just about
anything on the console, and it sounds to me like your grey-areas around
Rails itself are getting in the way of you learning how the GooglePlaces
object works.
If you have questions that are specific to the Google places gem you are
using, I recommend you open an issue or ask on the support forum
dedicated to the Google places gem. This list is generally for stuff
related to the framework of Rails itself (although we do often point
people in the right direction if they ask about common gems).

def index
def new
# @location.find_closest_shops(@location.params[:address])
Here is the input form
<%= form_for @location do |f| %>
<%= f.label :address %>
<%= f.text_field :address, :placeholder => “City State” %>
<%= f.submit “Find Coffee!” %>
<% end %>

<%= 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
Ok so I figured out what I did wrong sorta, the way the call was being
made
didnt work so I did this
def create @shops = [] @client =
GooglePlaces::Client.new(‘AIzaSyCC5Dyjn5_gGSKZMVJqF6tKOYOaxgUMJ8s’) @shops = @client.spots_by_query('coffee near ’ + @location.address)
end
now my next (and I think last problem) is in my input form I assumed
that
was setting @location’s address to w/e the string in the input field is
but
it’s saying it’s nil??
in my index I’m calling @location = Location.new, then I thought I was
setting @location.address to “input value from form”, what am I missing?
