Rails工厂协会失败

我一直在为这一整天而战。这个问题与Fabrication或FactoryGirl相同，所以我想它与Active Record或Rails有关。Rails工厂协会失败

让我们以下面的代码：

# app/models/category.rb 
class Category < ActiveRecord::Base 
    before_validation :set_order 

    # Associations ------------------ 
    belongs_to :company 

    # Validations ------------------- 
    validates :name, :order, :presence => true 
    validates :order, :uniqueness => { :scope => :company, :message => "order should be unique" } 

    def set_order 
    return unless self.order.nil? || self.order.blank? 

    company_categories = self.template && self.company.categories.template || self.company.categories.non_template 
    self.order = (company_categories.empty? && 1) || (company_categories.map(&:order).sort.last + 1) 
    end 
end 

# spec/factories/companies.rb 
Fabricator :company do 
    Fabricate.sequence(:name) { |n| "Company #{n}" } 
    creation_date Date.today 
    template false 
end 


# spec/factories/categories.rb 
Fabricator :category do 
    name ["Business", "Finance", "Analytics"][Random.rand(3)] 
    template false 
    company 
end 


# spec/models/category_spec.rb 
require 'spec_helper' 

describe Category do 
    let(:category) { Fabricate(:category) } 

    it "has a valid factory" do 
    category.should be_valid 
    end 

end

我每次运行规范，我得到以下错误：

1) Category has a valid factory 
    Failure/Error: let(:category) { Fabricate(:category) } 
    ActiveRecord::StatementInvalid: 
    PG::Error: ERROR: column categories.company does not exist 
    LINE 1: ..."categories" WHERE ("categories"."order" = 1 AND "categorie... 
                   ^
    : SELECT 1 AS one FROM "categories" WHERE ("categories"."order" = 1 AND "categories"."company" IS NULL) LIMIT 1 
    # ./spec/models/category_spec.rb:4:in `block (2 levels) in <top (required)>' 
    # ./spec/models/category_spec.rb:7:in `block (2 levels) in <top (required)>'

它看起来像没有设置正确的关联。对于sql查询是“categories”，“company”而不是“categories”，“company_id”。这是超级怪异的。

感谢您的帮助！

它试图在订单上运行验证。你的范围是company这是它从company而不是company_id。尝试：

validates :order, :uniqueness => { :scope => :company_id }
