rails nested_attributes窗体找不到id
rails nested_attributes窗体找不到id
提问于 2020-05-12 03:06:19
所以我有两种模式:实习和复习。我希望《评论》是一份nested_attributs of Internship。这样我就可以创建一个带评论的实习岗位了。
我的问题是，新的实习表单中集成的审查表单，找不到实习的id。它引发了“审查实习必须存在”的错误
Internship.rb
has_many :reviews, foreign_key: "review_internship_id"
has_many :review_users, foreign_key: 'review_user_id', class_name:"User", through: :reviews
accepts_nested_attributes_for :reviews, allow_destroy: true
validates_associated :reviewsReview.rb
belongs_to :review_user, class_name: "User"
belongs_to :review_internship, class_name: "Internship"Internship_controller
def new
@internship = Internship.new
@internship.reviews.new
end
def create
@internship = Internship.new(internship_params)
@internship.user = current_user
@internship.reviews.first.review_user_id = current_user.id
respond_to do |format|
if @internship.save
format.html { redirect_to @internship, notice: 'Expérience crée avec succès' }
format.json { render :show, status: :created, location: @internship }
else
format.html { render :new }
format.json { render json: @internship.errors, status: :unprocessable_entity }
end
end
end
private
def internship_params
params.require(:internship).permit(:adress, :zipcode, :city, :specialty, :organization, :population, :cursus, :title, :duration, :description, :region, :remuneration, :user_id, reviews_attributes: [:title, :notation, :description, review_internship_id: params[:internship_id], review_user_id: current_user.id])
end实习中的新形式新
<%= form_with(model: internship, local: true) do |form| %>
....
<!--NESTED ATTRIBUTS REVIEW-->
<%= form.fields_for :reviews do |p| %>
<%= p.label :titre %>
<%= p.text_field :title, class:"form-control" %>
<%= p.label :note %>
<%= p.number_field :notation, min: 1, max: 5, class:"form-control" %>
<%= p.label :description %>
<%= p.text_area :description, class:"form-control" %>
<% end %>
...
<% end %>这就是我在实习生控制器中尝试过的
@intership.reviews.review_internship_id = @internship.id这样它就可以找到实习生的id。错误是“审查实习期必须存在”。
它对“评论用户”也是如此，这个问题是用@internship.reviews.first.review_user_id = current_user.id解决的
你知道问题出在哪里吗，我怎么才能找到实习生id呢？我也尝试过params:id
谢谢你的帮忙

你在评论时并不需要user_id外键，因为它可以通过面试到达那里：
class Review
belongs_to :internship
has_one :user, through: :interview
end
class Internship
belongs_to :user
has_many :reviews
end
class User
has_many :internships
has_many :reviews, through: :internships
end而且您绝对不需要手动为嵌套记录分配父ids。
class IntershipsController < ApplicationController
def new
@internship = Internship.new
@internship.reviews.new
end
def create
@internship = Internship.new(internship_params) do |i|
i.user = current_user
end
respond_to do |format|
if @internship.save
format.html { redirect_to @internship, notice: 'Expérience crée avec succès' }
format.json { render :show, status: :created, location: @internship }
else
format.html { render :new }
format.json { render json: @internship.errors, status: :unprocessable_entity }
end
end
end
private
def internship_params
# use some line-breaks!
params.require(:internship)
.permit(
:adress, :zipcode, :city, :specialty,
:organization, :population, :cursus,
:title, :duration, :description,
:region, :remuneration, :user_id,
reviews_attributes: [
:id, :title, :notation, :description
]
)
