Review オブジェクトを作成しようとすると、次のエラーが発生します。
ArgumentError in ReviewsController#create
wrong number of arguments (1 for 0)
app/controllers/reviews_controller.rb:17:in `new'
app/controllers/reviews_controller.rb:17:in `create'
私が間違っていることを理解していませんか？他のオブジェクトを作成できますが、これらのオブジェクトでこのエラーが発生します。何をしても問題ありません。私は議論を入れないようにしていますが、それでも議論があると考えています...
私のモデルReview:
# -*- encoding : utf-8 -*-
class Review < ActiveRecord::Base
attr_accessible :global_validation_date, :hr_comment, :hr_validate, :hr_validator, :manager_comment, :manager_validate, :manager_validation_date, :manager_validator, :owner_satisfaction, :owner_validate, :owner_validation_date, :send, :user_id
belongs_to :user
has_many :review_projects, dependent: :destroy
end
私のコントローラーReviewsController：
# -*- encoding : utf-8 -*-
class ReviewsController < ApplicationController
before_filter :authenticate_user!
before_filter :check_permissions, only: :create
def index
@user = User.find(params[:user_id])
@reviews = @user.reviews
end
def create
@user = User.find(params[:user_id])
@reviews = @user.reviews
if @reviews.empty? || check_last_validate
@review = Review.new # HERE IS MY ERROR
if @review.save
render 'index', notice: "Review successfully created"
else
render 'index', notice: "An error occured on saving, please try again"
end
else
render 'index', alert: "You have to validate previous review before create a new one."
end
redirect_to user_reviews_path
end
private
def check_permissions
render_access_forbidden unless current_user == User.find(params[:user_id])
end
def check_last_validate
if !@reviews.empty?
return (@reviews.last.hr_validate || @reviews.last.manager_validate)
else
return false
end
end
end
SOで同じ質問をすべて読みましたが、何も機能しません。誤字脱字には気をつけていますが、間違ってはいないと思います。
オブジェクトを作成する 3 つの方法を試しましたReview。
@review = Review.new
@review.user_id = current_user.id
@review.hr_validator = ((current_user.hr_id.nil?) ? current_user.id : current_user.hr_id )
@review.manager_validator = ((current_user.manager_id.nil?) ? current_user.id : current_user.manager_id )
@review.hr_validate = false
@review.manager_validate = false
@review.owner_validate = false
@review.hr_comment = ""
@review.manager_comment = ""
@review.owner_satisfaction = nil
@review.send = false
@review = Review.new(
user_id: current_user.id,
hr_validator: ((current_user.hr_id.nil?) ? current_user.id : current_user.hr_id ),
manager_validator: ((current_user.manager_id.nil?) ? current_user.id : current_user.manager_id ),
hr_validate: false,
manager_validate: false,
owner_validate: false,
hr_comment: "",
manager_comment: "",
owner_satisfaction: nil,
send: false )
@user.reviews.create!(
user_id: current_user.id,
hr_validator: ((current_user.hr_id.nil?) ? current_user.id : current_user.hr_id ),
manager_validator: ((current_user.manager_id.nil?) ? current_user.id : current_user.manager_id ),
hr_validate: false,
manager_validate: false,
owner_validate: false,
hr_comment: "",
manager_comment: "",
owner_satisfaction: nil,
send: false )
最後のものは、次を除いて同じエラーを出します:
wrong number of arguments (2 for 0)
Ruby のバージョンは 1.9.3、Rails のバージョンは 3.2.13 です。
ありがとう。

Railsコンソールでこのコードを試してみると:
current_user = User.first # as you are inside rails console you wont have current_user available to you
@review = Review.new(user_id: current_user.id,
hr_validator: ((current_user.hr_id.nil?) ? current_user.id : current_user.hr_id ),
manager_validator: ((current_user.manager_id.nil?) ? current_user.id : current_user.manager_id ),
hr_validate: false,
manager_validate: false,
owner_validate: false,
hr_comment: "",
manager_comment: "",
owner_satisfaction: nil,
send: false )
@review.save
このエラーが発生します：
