未找到参数：first_name | LegaciesController#create 中的 ActionController::ParameterMissing

Question

我收到错误：param not found: first_name | ActionController::ParameterMissing in LegaciesController#create

开启

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

这是我的控制器

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

这是我的遗产/新观点：

%= 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>

我忽略了什么？

Answer 1

应该是

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
