Question

每次我为模型类Spec：

运行RSpec测试时，我都会收到此错误

NoMethodError: undefined method `new' for Spec:Module

我已经查看了spec模型类中是否存在任何预期的模型方法，并且找不到任何模型方法。

我可以使用＆＃39;规格＆＃39;作为模型名称，如果我正在使用RSpec或是否有解决方法？

spec.rb（Rails模型）

class Spec < ApplicationRecord
  belongs_to :scenario

  validates :scenario_id, presence: true
  validates :description, presence: true,  length: { minimum: 1, maximum: 100 }
  validates :selected_section, presence: true, length: { maximum: 200 }
  validates :selected_action, presence: true, length: { maximum: 200 }
end

spec_spec.rb

 require 'rails_helper'

    RSpec.describe Spec, type: :model do
      context 'Relationship' do
        it 'should belong to project' do
          should belong_to(:scenario)
        end
      end

      context 'Validations' do
        let(:f) {FactoryGirl.build(:scenario)}
        subject do
          FactoryGirl.build(:spec, scenario: f)
        end
        it 'Correct input to be valid' do
          expect(subject).to be_valid
        end
        context 'scenario_id, needs to be' do
          it 'presence' do
            should validate_presence_of(:feature_id)
          end
        end
        context 'description, needs to be' do
          it 'presence' do
            should validate_presence_of(:description)
          end
          it 'minimum length of 1' do
            should validate_length_of(:description).is_at_least(1)
          end
          it 'maximum length of 100' do
            should validate_length_of(:description).is_at_most(100)
          end
        end
        context 'selected_section, needs to be' do
          it 'presence' do
            should validate_presence_of(:selected_section)
          end
          it 'maximum length of 100' do
            should validate_length_of(:selected_section).is_at_most(200)
          end
        end
        context 'selected_action, needs to be' do
          it 'presence' do
            should validate_presence_of(:selected_action)
          end
          it 'maximum length of 100' do
            should validate_length_of(:selected_action).is_at_most(200)
          end
        end
      end
    end

正如您已经猜到的，您在Spec课程与RSpec's Spec module之间发现了命名空间冲突。

以下是解决问题的两种方法。

将您的类及其文件名重命名为Rails.root / models / the_spec.rb

class TheSpec < ApplicationRecord
  belongs_to :scenario

  # ... your code
end

命名空间，将其移至Rails.root / models / internal / spec.rb

class Internal::Spec < ApplicationRecord
  belongs_to :scenario

  # ... your code
end

您还需要编辑和移动/重命名spec_spec.rb文件以匹配。

名为Spec的模型类的Rspec问题没有预期的模型类方法
