未找到參數：first_name | ActionController的:: ParameterMissing在LegaciesController＃創建

Question

我收到錯誤：param not found: first_name | ActionController::ParameterMissing in LegaciesController#create

在

private 
    def link_params 
     params.require(:first_name).permit(:id, :last_name, :legacy_donations, :address, :city, :state, :zip_code, :gender, :date_of_birth, :Marital_status, :Spouses_name, :comments) 
    end 

end 

這是我的控制器

class LegaciesController < ApplicationController 

    def index 
    end 

    def new 
     @legacy = Legacy.new 
    end 

    def create 
     @legacy = Legacy.new(link_params) 
     if @legacy.save 
      redirect_to @legacy 
     else 
      render action: 'new' 
     end 
    end 

    def show 
    end 

    def destroy 
    end 

    def edit 
    end 

    def update 
    end 

private 
    def link_params 
     params.require(:first_name).permit(:id, :last_name, :legacy_donations, :address, :city, :state, :zip_code, :gender, :date_of_birth, :Marital_status, :Spouses_name, :comments) 
    end 

end 

這是我的遺產/新觀點：

%= form_for @legacy, html:{ role: "form", class: "new-legacy"} do |f| %> 
    <% if @legacy.errors.any? %> 
     <div id="error_explanation"> 
      <h1><%= pluralize(@legacy.errors.count, "error") %> prohibited this from being saved:</h1> 

       <ul> 
        <% @legacy.errors.full_messages.each do |msg| %> 
         <li><%= msg %></li>

應該

def link_params 
    params.require(:legacy).permit(:id, :first_name,:last_name, :legacy_donations, :address, :city, :state, :zip_code, :gender, :date_of_birth, :Marital_status, :Spouses_name, :comments) 
end
