Rails 测试-如何使用外键传递参数

  • 772

我正在尝试为控制器编写测试。“创建”操作需要表单数据，如果表单数据不符合要求，则会被拒绝为“无法处理的实体”：

Failure:
ContactsControllerTest#test_should_post_create [test/controllers/contacts_controller_test.rb:36]:
Expected response to be a <3XX: redirect>, but was a <422: Unprocessable Entity>

我在下面包括了模型、控制器、测试控制器和装置。授权仍然是开箱即用的，但在这里不应该成为因素（其他测试运行良好）。

我怀疑参数中的外键是罪魁祸首，但我不知道如何检查。我还在测试参数中尝试了@saluation.id 和@debitor.id。

模型

class Contact < ApplicationRecord
    validates :last_name, presence: true
    validates :email, format: {
        with: URI::MailTo::EMAIL_REGEXP
    }
    belongs_to :salutation
    belongs_to :debitor

控制器

class ContactsController < ApplicationController

  def create
      @contact = Contact.new(contact_params)
      @debitors = Debitor.all
      @salutations = Salutation.all
    
      if @contact.save 
        redirect_to contacts_path
      else
        render :new, status: :unprocessable_entity
      end
  end

  private
  def contact_params
    params.require(:contact).permit(:last_name, :first_name, :email, :salutation_id, :debitor_id)
  end

end

测试

require "test_helper"

class ContactsControllerTest < ActionDispatch::IntegrationTest
  setup do
    @user = users(:lazaro_nixon)
    @contact = contacts(:one)
    @salutation = salutations(:one)
    @debitor = debitors(:one)
  end


  test "should post create" do
    sign_in_as @user

    post contacts_url, :params => { :contact => { last_name: "Lastname", first_name: "Firstname", email: "[email protected]", salutation: @salutation, debitor: @debitor }}
    assert_response :redirect
    follow_redirect!
    assert_response :success
  end

end

装置 - 接触器

one:
  last_name: MyString
  first_name: MyString
  email: MyString
  salutation: one
  debitor: one

固定装置 - 致意

one:
  salutation: MyString

固定装置 - 债务人

one:
  company: MyString
  street: MyString
  house_number: MyString
  zip: 1
  city: MyString
  payment_terms: one

  1. 我认为你的测试参数键应该salutation_id是debitor_id

    您需要传递记录的 id 而不是整个记录，并使用与预期参数相同的键名。

    require "test_helper"

class ContactsControllerTest < ActionDispatch::IntegrationTest
  setup do
    @user = users(:lazaro_nixon)
    @contact = contacts(:one)
    @salutation = salutations(:one)
    @debitor = debitors(:one)
  end

  test "should post create" do
    sign_in_as @user
    # - don't mix in a bunch of hashrockets
    # - use linebreaks for readibility
    post contacts_url, params: { 
      contact: { 
        last_name: "Lastname", 
        first_name: "Firstname", 
        email: "[email protected]", 
        salutation_id: @salutation.id, 
        debitor_id: @debitor.id
      }
    }
    assert_response :redirect
    follow_redirect!
    assert_response :success
  end
end

    但测试可以稍加改进，以便真正测试控制器操作的重要方面。

    # be descriptive
test "should create contact with valid params" do
  sign_in_as @user 
  assert_difference ->{ Contact.count }, 1 do
    post contacts_url, params: { 
    contact: { 
      last_name: "Lastname", 
      first_name: "Firstname", 
      email: "[email protected]", 
      salutation_id: @salutation.id, 
      debitor_id: @debitor.id
    }
  }
  assert_redirected_to Contact.last
end

    这将测试该记录是否真正创建以及位置是否是最后创建的记录，而不仅仅是控制器将您重定向到任意路径，这会让您很容易受到误报的影响。
