Question

我是Ruby的新手，我正在Nitrous开发自己的应用程序。

当我在new.html.erb上填写表单并点击“保存”时，show视图会加载。该页面按预期呈现HTML标题，但我的模型没有数据字段。我也尝试了索引视图，但我认为没有保存数据。

我已经生成了一个名为income的模型，并且运行了rake db：migrate，并且设置了正确的表。我对这个问题感到困惑。

感激地收到任何想法。

这是我的控制器：incomes_controller.rb

class IncomesController < ApplicationController 

  def index
  @incomes = Income.all
end

def new
  @income = Income.new
end

def create
 @income = Income.new(income_params)
 if @income.save
  redirect_to(:action => 'show', :id => @income.id)
 end
end

def show
 @income = Income.find(params[:id])
end


private

def income_params
 params.require(:income).permit(:first_name, :last_name, :date_of_birth, :income1, :income2, :income3, :income4, :income5, :income6, :income7, :income8, :income9, :income10)
 end
end

我在new.html.erb中的表单是：

<%= simple_form_for @income do |f| %>  
    <%= f.input :first_name, label: 'First Name' %> 
    <%= f.input :last_name, label: 'Last Name' %> 
    <%= f.input :date_of_birth, label: 'Date of Birth', hint: 'dd/mm/yyyy' %> 

<p>Income: Salary or Wages</p>
<%= f.input  :income1, label: 'Take home salary or Wage' %>
<%= f.input  :income2, label: 'Partner\'s salary or wage' %>
<%= f.input  :income3, label: 'Other income from salary or wages' %>

<p>Other Income</p>
<%= f.input  :income4, label: 'Maintanence or child support' %>
<%= f.input  :income5, label: 'Boarders or lodgers' %>
<%= f.input  :income6, label: 'Non-dependent contributions' %>
<%= f.input  :income7, label: 'Student loands or grants' %>
<%= f.input  :income7, label: 'Other' %>

<p>Benefits </p>
<%= f.input  :income8, label: 'Sample input' %>
<%= f.input  :income9, label: 'Sample input' %>
<%= f.input  :income10, label: 'More sample inputs' %>

<%= f.button :submit, "Save and Proceed" %>
<h3>You will have a chance to review your form before you submit it.  Once you click Save, you can come back and complete the rest of the form at a later date</h3>

<% end %>

我的show.html.erb文件是：

<p>
  <strong>First name:</strong>
  <%= @income.first_name %>
</p>

<p>
  <strong>Last name:</strong>  
  <%= @income.last_name %>
</p>

<p>
  <strong>Date of Birth:</strong>  
  <%= @income.date_of_birth %>
</p>

<p>
  <strong>Take home salary or Wage:</strong>  
  <%= @income.income1 %>
</p>

我的模型income.rb是：

class Income < ActiveRecord::Base
attr_accessor :first_name, :last_name, :date_of_birth, :income1, :income2, :income3, :income4, :income5, :income6, :income7, :income8, :income9, :income10 
end

开发日志输出....

Answer 1

感谢@RailsOuter和@jyrkim的帮助。我发现问题确实存在于我的模型文件和迁移文件中。

我需要从模型中删除attr_accessor行。我发现我必须修改我的迁移文件以添加列，而不是生成新的迁移。现在我已经使用数据列生成了新的迁移，我的数据正在显示！

再次感谢，非常感谢您的帮助，帮助新手！

Ruby Index和Show视图不显示任何数据
