Rails Geocoder gem显示结果

Question

I'm using the geocoder gem in order to set the longitude and latitude from the address:

 class Ub < ApplicationRecord

  geocoded_by :full_address
  after_validation :geocode, if: ->(obj){ obj.full_address.present? }

  def full_address
    [street, city, state, zip_code, country].join(",")
  end
end

end search:

class SearchController < ApplicationController

  def search
    if params[:search].present?
      location_info = request.location
      @ubs = Ub.near([location_info.latitude, location_info.longitude], 5, :order => :distance)
    else
      @ubs = []
    end
  end

Answer 1

Without more information on what the latitude/longitude values of your items are, it's tough to say for sure, but what jumps out at me from your query is this:

WHERE (items.latitude BETWEEN -0.07236589155542399 AND 0.07236589155542399 AND items.longitude BETWEEN -0.07236589155542399 AND 0.07236589155542399)

Those upper and lower limits on latitude/longitude represent a small area off the western coast of Africa, so I'm not surprised that none of your items are located there.

What values are being returned by location_info = request.location ? Also, did you see this section from the documentation ?

Note that these methods will usually return nil in your test and development environments because things like "localhost" and "0.0.0.0" are not an Internet IP addresses.
