Rails 日期因型号而更改

我有一个带有日期选择的表格。

我有以下形式：

<%= date_select :user, :birthday, {:start_year => Time.now.year, :end_year => 1910,:order => [:day,:month,:year], :prompt => { :day => 'day', :month => 'month', :year => 'year' }}, { :class => "default" } %>

模型中的验证：

validates :birthday, :if => :should_validate_birthday?,
           :presence => {:message => "Please enter your friend's birthdate"},
           :date =>     { :after => Date.civil(1910,1,1), :before => Date.today, :message => "Please enter a valid date"}

这是用户在日志中提交内容的示例：

"user"=>{"name"=>"rewrwe", "birthday(3i)"=>"1", "birthday(2i)"=>"", "birthday(1i)"=>"2008", "email"=>""}}

请注意，月份的值为空。

在控制器中，我创建用户，

create
@user = User.new(params[:user])

If @user.save
#go to the confirm page
end

end

即使缺少月份，也不会显示错误消息，因为由于某种原因，当我尝试保存模型时，它将空月份转换为“一月”或 01。

这非常令人沮丧，因为我不这样做希望用户意外提交错误数据。

我怎样才能阻止 Rails 这样做并确保提交所有日期信息？

I have a form with a date select.

I have the following form:

<%= date_select :user, :birthday, {:start_year => Time.now.year, :end_year => 1910,:order => [:day,:month,:year], :prompt => { :day => 'day', :month => 'month', :year => 'year' }}, { :class => "default" } %>

Validation in my model:

validates :birthday, :if => :should_validate_birthday?,
           :presence => {:message => "Please enter your friend's birthdate"},
           :date =>     { :after => Date.civil(1910,1,1), :before => Date.today, :message => "Please enter a valid date"}

Here is an example of what the user submits in the log:

"user"=>{"name"=>"rewrwe", "birthday(3i)"=>"1", "birthday(2i)"=>"", "birthday(1i)"=>"2008", "email"=>""}}

NOTE that the value for the month is blank.

IN the controller I create the user

create
@user = User.new(params[:user])

If @user.save
#go to the confirm page
end

end

No error messages are shown even though the month is missing because for some reason when I try to save the model it converts an empty month to "January" or 01.

This is very frustrating as I don't want users to submit bad data by accident.

How can I stop Rails from doing this and make sure all the date information is submitted?

用 attr_accessor 分隔三个字段：

class User < ActiveRecord::Base
  attr_accessor :birthday_year, :birthday_month, :birthday_date
  validates_presence_of :birthday_year, :birthday_month, :birthday_date
  # ...
end

然后在您的视图中，每个字段都有不同的选择。这就是 date_select 所做的全部工作，但它在视图中而不是在模型中将它们分开，这使得验证每个字段变得困难。

Separate the three fields with attr_accessor:

class User < ActiveRecord::Base
  attr_accessor :birthday_year, :birthday_month, :birthday_date
  validates_presence_of :birthday_year, :birthday_month, :birthday_date
  # ...
end

And then in your view just have different selects for each of them. That's all the date_select does but it splits them up in the view, rather than in the model, which makes it hard to validate each field.
