I have been trying for many years to figure out how to include gmaps4rails in a rails application.
I made a completely new application and tried a new one.
I can not understand what is happening. I am looking for installation instructions that are complete and up to date. Many SO posts relate to older versions of dependencies, which ultimately indicate that a problem has been resolved in a later version.
Currently I have this in my opinion:
<script src="//maps.google.com/maps/api/js?v=3.23&key=<%= ENV['GOOGLE_MAPS_API_KEY'] %>"></script>
<script src="//google-maps-utility-library-v3.googlecode.com/svn/tags/markerclustererplus/2.0.14/src/markerclusterer_packed.js" type="text/javascript"></script>
<div style='width: 800px;'>
<div id="map" style='width: 800px; height: 400px;'></div>
</div>
<script type="text/javascript">
handler = Gmaps.build('Google');
handler.buildMap({ provider: {}, internal: {id: 'map'}}, function(){
markers = handler.addMarkers(<%=raw @hash.to_json %>);
handler.bounds.extendWith(markers);
handler.fitMapToBounds();
});
</script>
In my application.js application, I have:
I saved the production version of underscore.js in the vendor / assets / javascripts folder. I also saved the markerclusterer.js file in a file in the same folder.
In my gem file, I have:
gem 'geocoder'
gem 'gmaps4rails', '~> 2.1', '>= 2.1.2'
gem 'countries'
gem 'country_select'
In my controller, I have:
class AddressesController < ApplicationController
def index
end
def show
@hash = Gmaps4rails.build_markers(@address) do |address, marker|
marker.lat address.latitude
marker.lng address.longitude
end
end
def new
@address = Address.new
end
def create
@address = Address.new(address_params)
respond_to do |format|
if @address.save
format.html { redirect_to @address, notice: 'Address was successfully created.' }
format.json { render :show, status: :created, location: @address }
else
format.html { render :new }
format.json { render json: @address.errors, status: :unprocessable_entity }
end
end
end
private
def set_address
@address = Address.find(params[:id])
end
def address_params
params[:address].permit(:unit, :building, :street_number, :street, :city, :region, :zip, :country, :time_zone, :latitude, :longitude)
end
def user_time_zone(&block)
Time.use_zone(current_user.time_zone, &block)
end
end
When I try to display a view using a map, the chrome inspector shows errors like:
