Ruby on rails Ruby索引和显示视图未显示任何数据

我是Ruby新手，我正在Nitrous中开发自己的应用程序

当我在new.html.erb上完成表单并点击save时，将加载show视图。页面按预期呈现HTML标题，但没有来自我的模型的数据字段。我也尝试过索引视图，但我认为没有保存任何数据

我已经生成了一个名为income的模型，并在设置了正确的表的情况下成功运行rakedb:migrate。我弄不清问题出在哪里

任何想法都受到了感激

这是我的控制器：www.u 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

感谢@RailsOuter和@jyrkim的帮助。我发现问题确实出在我的模型文件和迁移文件上

我需要从模型中删除行属性访问器。后来我发现，我必须修改迁移文件以添加列，而不是生成新的迁移。现在我已经用数据列生成了新的迁移，我的数据正在显示

再次感谢，非常感谢您为帮助新手所做的贡献

重定向到（：action=>'show'，：id=>@income.id）

将create中的这一行替换为这一行，然后尝试

重定向到@post，注意：'income已成功创建。

在show页面中只需打印

@income

值谢谢。我在点击save后收到错误：“ActionController:：ActionControllerError in IncomesController#create无法重定向到nil！”想法？您的收入是否保存到数据库中？您使用的rails版本是什么？如果4，那么你不需要这行属性访问器：名字、姓氏、出生日期、收入1、收入2、收入3、收入4、收入5、收入6、收入7、收入8、收入9、收入10据我所知，我的强势参数非常紧张。。。
