无法为多个孩子创建资助表

Question

每个孩子都可以申请资助。但是，当我申请资助时，它总是为Child_id创建资助申请：1，即使我正在申请其他孩子。资金属于儿童，儿童可以有很多资金。请帮忙

fundings_controller.rb

def create
  @funding = Funding.new(funding_params)

  @funding.child = Child.find(child_user.ids[0])
    if @funding.save
      flash[:success] = "Thankyou for submitting"
      redirect_to funding_path(@funding)
    else 
      render 'new'
    end
end

application_controller.rb

def current_user
  @current_user ||= Family.find(session[:family_id]) if session[:family_id]
  end

  def parent_user
  @parent_user ||= Parent.find(session[:family_id]) if session[:family_id]
  end

  def child_user
    puts session[:family_id]
  @child_user ||= Child.where(:parent_id=>session[:family_id]).limit(1) if session[:family_id]
end

funding.rb

class Funding < ApplicationRecord
    has_many :organisations
    accepts_nested_attributes_for :organisations, reject_if: :all_blank, allow_destroy: true
    belongs_to :child
end

child.rb

class Child < ApplicationRecord
    belongs_to :parent
    has_many :fundings
    validates :parent_id, presence: true
    validates :firstname, presence: true
    validates :lastname, presence: true
    validates :dateofbirth, presence: true
end

parent.rb

class Parent < ApplicationRecord
    has_many :children, dependent: :destroy
    has_many :secondaryparents, dependent: :destroy
    accepts_nested_attributes_for :secondaryparents, reject_if: :all_blank, allow_destroy: true
    belongs_to :family
    validates :parent_1_firstname,   presence: true
    validates :parent_1_lastname,    presence: true
    validates :address,              presence: true
    validates :city,                 presence: true
    validates :telephone_number,     presence: true
    validates :postal_code,          presence: true
    validates :email,                presence: true
    validates :family_id,            presence: true
end

family.rb

class Family < ApplicationRecord
    has_many :parents, dependent: :destroy

    before_save { self.email = email.downcase }
    VALID_EMAIL_REGEX = /\A[A-Za-z0-9.]+@[A-Za-z0-9]+\.[A-Za-z]+\z/i
    validates :email, presence: true, uniqueness: {case_sensitive: false}, format: { with: VALID_EMAIL_REGEX }

    has_secure_password

Answer 1

由于父母一次只能为一个孩子申请资助，所以让他们选择资助形式的孩子，并将：child_id作为资助参数的一部分传递给FundingsController #create action。

fundings_controller.rb：

def create
  @funding = Funding.new(funding_params)

  if @funding.save
    flash[:success] = "Thankyou for submitting"
    redirect_to funding_path(@funding)
  else 
    render 'new'
  end
end

application_controller.rb

def current_user
  @current_user ||= Family.find(session[:family_id]) if session[:family_id]
end

def parent_user
  @parent_user ||= Parent.find(session[:family_id]) if session[:family_id]
end

def current_children
  puts session[:family_id]
  @current_children ||= Child.where(:parent_id => parent_user.id) if session[:family_id]
end
helper_method :current_children

Answer 2

查看模型，这应该是数据库表的一部分。

|Family |Parent    |Child      |Funding   |Organisation  |
|-------+----------+-----------+----------+--------------|
|id     | id       | id        |id        |id            |
|-------+----------+-----------+----------+--------------|
|       |family_id |parent_id  |child_id  |founding_id   |

我看到的问题是，当您创建新资金时，您只能添加一个孩子。但是你有一个集合，然后限制为1才能使它工作。

但是您只添加了为current_user（.limit(1)）提取的第一个子项。

你应该做的是属于父母的每一个属于current_user（在家庭中找到）的孩子，你需要创建一个新的资助。

但代码变化很大。删除.limit(1)以获取所有子集合，扫描集合并为每个孩子创建资金。

但我认为您需要在不同的控制器中为此创建一个新动作。

或者，但我不知道您的目的，请考虑在Child和Funding之间使用其他关联，例如has_and_belongs_to_many。
