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.
