issue with mongoid and rails when do seed its faild-Collection of common programming errors

first is the status:

class Status
  include Mongoid::Document
  field :name, type: String
  has_one :Apis
  validates_presence_of :name
end

as well have APIS:

class Apis
  include Mongoid::Document
  field :name, type: String
  field :description, type: String, default: ''
  field :create_at, type: DateTime, default: ->{ DateTime.now }

  belongs_to :Status
  validates_presence_of :name
end

the SEED file:

# This file should contain all the record creation needed to seed the database with its default values.
# The data can then be loaded with the rake db:seed (or created alongside the db with db:setup).
#
# Examples:
#
#   cities = City.create([{ name: 'Chicago' }, { name: 'Copenhagen' }])
#   Mayor.create(name: 'Emanuel', city: cities.first)
if Status.count == 0 
    Status.create({name: "active"})
    Status.create({name: "inactive"})
    Status.create({name: "pending"})
    Status.create({name: "rejected"})
    Status.create({name: "sending"})
    Status.create({name: "contentItemPending"})
    Status.create({name: "contentItemListed"})
    Status.create({name: "staticItemListed"})
    Status.create({name: "requestItemPending"})
end

if Apis.count == 0 
    active_status = Status.find_by({name:"active"})
    youtub = Apis.new({name:"youtube", description:"Youtube API Used youtube_it gem"})
    youtub.build_Status(active_status.id)
    youtub.save!
    itunes = Apis.new({name:"itunes", description:"ITUNES API Used itunes gem"})
    itunes.build_Status(active_status.id)
    itunes.save!
    factual = Apis.new({name:"factual", description:"FACTUAL API Used FACTUAL gem"})
    factual.build_Status(active_status.id)
    factual.save!
end

now i get this error:

now i got no clue what i doing here wrong what is here not work???

as well its make at line 23 means youtub.build_Status(active_status.id) to uninitialized constant Statu why???

ok Guys its work my error was this: belongs_to :Status , class_name: ‘something’ and has_one :Apis ,class_name:’something’ and the seeder need added like this:

Mongoid.purge!
if SystemStatus.count == 0 
    SystemStatus.create!({name: "active"})
    SystemStatus.create!({name: "inactive"})
    SystemStatus.create!({name: "pending"})
    SystemStatus.create!({name: "rejected"})
    SystemStatus.create!({name: "sending"})
    SystemStatus.create!({name: "contentItemPending"})
    SystemStatus.create!({name: "contentItemListed"})
    SystemStatus.create!({name: "staticItemListed"})
    SystemStatus.create!({name: "requestItemPending"})
end

if Providers.count == 0 
    active_status = SystemStatus.find_by({name:"active"})
    Providers.create!({name:"youtube", description:"Youtube API Used youtube_it gem",status: active_status})
    Providers.create!({name:"itunes", description:"Youtube API Used youtube_it gem",status: active_status})
    Providers.create!({name:"youtube", description:"Youtube API Used youtube_it gem",status: active_status})
    Providers.create!({name:"unknown", description:"Rest service conntection",status: active_status})
end

what that went wrong here was that it didnt know what class to go to as well how i enter the data

  1. Besides the s missing, which that’s what it looks like, I’m not sure if the Status.count will even work, I think you need to use Status.all.count, and other thing is you should use Status.create! with a bang (!). It will raise an exception if if there’s an error. IF you use it without the bang, it’ll return false but you won’t know there’s a problem.

  2. You may have to set custom inflectors for your Status model. Fire up a console and try running "status".singularize to see what you get.
