在控制器中设置字段

Question

创建新人时，如何设置未包含在new.html.erb表单中的字段？

这里是控制器和形状：

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 %> 

这里有机型：

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 

的关联方法@person = location.persons.build工作在滑轨控制台细。它将'linkable_id'字段设置为1，将'linkable_type'字段设置为'位置'。但是，在提交表单后，Person被创建，但这两个字段留空。

任何有关这个问题的帮助将不胜感激。

您正在新行动中构建人物对象。你必须建立相同的创建操作以及..

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
