Activerecord Rails日期\选择并更新\属性

我要把头发扯下来了，所以我肯定错过了一些基本的东西

我有以下表格（简化）：

Rails logger报告了以下表单结果（简化）：

问题是：Rails似乎没有像预期的那样将这三个字段的参数转换为数据库的date和datetime对象。Rails记录器报告的查询为：

UPDATE `public_calls` SET `start_date`=NULL, `end_date`=NULL, `submission_deadline`=NULL, `updated_at`='2012-03-20 20:47:15' WHERE...

知道是什么吗

顺便说一句，Rails 3.2.0/Ruby 1.9.3。公共调用模型上的my属性均不受保护

谢谢

编辑

还尝试使用带有更新属性的：无保护选项！但这也不行

编辑#2

我已尝试调试ActiveRecord的AttributeAssignment模块中发生的情况，如下所示：

def assign_multiparameter_attributes(pairs)
  Rails.logger.info('ASSIGN_MULTIPARAMETER_ATTRIBUTES: '+pairs.inspect)
  execute_callstack_for_multiparameter_attributes(
    extract_callstack_for_multiparameter_attributes(pairs)
  )
end

def execute_callstack_for_multiparameter_attributes(callstack)
  errors = []
  Rails.logger.info('EXECUTE_CALLSTACK_FOR_MULTIPARAMETER_ATTRIBUTES: '+callstack.inspect)
  callstack.each do |name, values_with_empty_parameters|
    begin
      send(name + "=", read_value_from_parameter(name, values_with_empty_parameters))
    rescue => ex
      errors << AttributeAssignmentError.new("error on assignment #{values_with_empty_parameters.values.inspect} to #{name}", ex, name)
    end
  end
  unless errors.empty?
    raise MultiparameterAssignmentErrors.new(errors), "#{errors.size} error(s) on assignment of multiparameter attributes"
  end
end

def extract_callstack_for_multiparameter_attributes(pairs)
  Rails.logger.info('EXTRACT_CALLSTACK_FOR_MULTIPARAMETER_ATTRIBUTES: '+pairs.inspect)
  attributes = { }
  pairs.each do |pair|
    multiparameter_name, value = pair
    attribute_name = multiparameter_name.split("(").first
    attributes[attribute_name] = {} unless attributes.include?(attribute_name)
    parameter_value = value.empty? ? nil : type_cast_attribute_value(multiparameter_name, value)
    attributes[attribute_name][find_parameter_position(multiparameter_name)] ||= parameter_value
  end
  Rails.logger.info('EXTRACT_CALLSTACK_FOR_MULTIPARAMETER_ATTRIBUTES: '+attributes.inspect)
  attributes
end

你知道为什么没有调用execute\u callstack\u for\u multiparameter\u attributes方法吗？

升级你的rails版本-我也遇到了同样的问题，从V3.2.0升级到V3.2.8为我解决了这个问题

我也有这个问题。你能弄明白吗？我也有这个问题。你能弄明白吗？rails变更日志中有关于这些方法的内容吗？rails变更日志中有关于这些方法的内容吗？
