Question

在视图中（/employees/new.html.erb）

<%= form_for(@employee) do |f| %>
    <%= f.label(:name, "Name of Employee") %>
    <%= f.text_field(:name)%></br>

    <%= f.label(:email, "Email id") %>
    <%= f.text_field(:email) %></br>

    <%= f.label(:password, "Password") %>
    <%= f.text_field(:password) %></br>

    <%= f.label(:city_id, "city") %>
    <%= f.collection_select(:city_id, @city, :id, :city_name)%></br>

    <%= f.label(:time_zone, "choose time zone") %>
    <%= f.time_zone_select(:time_zone) %></br>

    <%= f.label(:birth_date, "Date of Birth")%>
    <%= f.date_select(:birth_date) %></br></br>

    <%= f.submit "add employee" %>
<% end %>

在员工控制器中，

  def new
    @employee = Employee.new(:city_id => 11)
    @city = City.all
  end

  def create
    @employee = Employee.new(params[:employee])
    @employee.save
    redirect_to :action => :index
  end

在员工模型中

class Employee < ActiveRecord::Base
  attr_accessible :email, :name, :password, :city_id, :time_zone, :birth_date
  belongs_to :city
end

但是，当我从浏览器提交表单时。我得到如下错误，

 ActiveRecord::MultiparameterAssignmentErrors in EmployeesController#create

1 error(s) on assignment of multiparameter attributes

除了date_select表单助手之外，一切都很完美，我认为，我应该在应用程序的某个地方实现以下代码。

"Date.civil(params[:start_date][:year].to_i, params[:start_date][:month].to_i, params[:start_date][:day].to_i)"

请有人帮我解决此问题。感谢
