Question

我有模特

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

视图中的此表单

= f.text_field :latitude
= f.text_field :longitude

这是控制器

...
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
...

在表单中填充纬度和经度，但是当我更改值并保存它时，它不起作用，甚至在数据库中更改了像地址这样的其他字段。但它在控制台中完美运行

> b = Building.first
> b.latitude = -7.27094221115
> b.save
 => true

Answer 1

我认为params上的问题，来自您拥有string纬度和经度的表单，但需要float。
