ruby-on-rails - 在 Controller 中设置字段

Question

新建Person时，如何设置new.html.erb表单中没有的字段？

这是 Controller 和表单:

class PeopleController < ApplicationController

    def new
        @account = Account.find_by_id(params[:account_id])
        organization = @account.organizations.primary.first
        location = organization.locations.primary.first
        @person = location.persons.build    
    end

    def create
        @person = Person.new(params[:person])
        if @person.save
            flash[:success] = "Person added successfully"
            redirect_to account_path(params[:account_id])
        else
            render 'new'
        end
    end
end


<h2>Account: <%= @account.organizations.primary.first.name %></h2>

<%= form_for @person do |f| %>

    <%= f.label :first_name %><br />
    <%= f.text_field :first_name %><br />
    <%= f.label :last_name %><br />
    <%= f.text_field :last_name %><br />
    <%= f.label :email1 %><br />
    <%= f.text_field :email1 %><br />
    <%= f.label :home_phone %><br />
    <%= f.text_field :home_phone %><br />
    <%= f.submit "Add person" %>

<% end %>

模型如下:

class Location < ActiveRecord::Base

    belongs_to :organization

    has_many :persons, :as => :linkable
    has_one :address, :as => :addressable

    scope :primary, where('locations.primary_location = ?', true)

    accepts_nested_attributes_for :address

end

class Person < ActiveRecord::Base

    belongs_to :linkable, :polymorphic => true

end

关联方法 @person = location.persons.build 在 Rails 控制台中运行良好。它将“linkable_id”字段设置为 1，将“linkable_type”字段设置为“Location”。但是，在提交表单后创建了 Person，但这两个字段留空。

非常感谢任何对此问题的帮助。

您正在新操作中构建人员对象。您还必须在创建操作中构建相同的内容..

def create
  # location = Calculate location here
  @person = location.persons.build(params[:person])
  if @person.save
    flash[:success] = "Person added successfully"
    redirect_to account_path(params[:account_id])
  else
    render 'new'
  end
end
