rail 4 coordinate isn't saved - ruby-on-rails-4

Question

I have model
class Building
include Mongoid::Document
include Geocoder::Model::Mongoid
field :address, :type => String, :default => ""
field :location, :type => Array, spacial: {lat: :latitude, lng: :longitude, return_array: true }
## Building index
index({location: "2d"})
def latitude
location[1]
end
def longitude
location[0]
end
def latitude=( lat )
location[1] = lat
end
def longitude=( lng )
location[0] = lng
end
end
this form in the view
= f.text_field :latitude
= f.text_field :longitude
and this is the controller
...
def create
#building = Building.new(building_params)
respond_to do |format|
if #building.save
format.html { redirect_to #building, notice: 'Building was successfully created.' }
format.json { render action: 'show', status: :created, location: #building }
else
format.html { render action: 'new' }
format.json { render json: #building.errors, status: :unprocessable_entity }
end
end
end
private
def building_params
params.require(:building).permit(:address, :latitude, :longitude)
end
...
The latitude and longitude are populated in the form, but when I change the value and save it, it didn't work, even the other field like address is changed in the database. But it's working flawlessly in console
> b = Building.first
> b.latitude = -7.27094221115
> b.save
=> true

Answer 1

i think problem on params, from form you have string latitude and longitude, but need float.
