Rails无效日期错误

Question

我正在使用此 gem在我的应用中设置日历。 除更改月份的箭头外，其他所有工具都工作正常。

ArgumentError in UsersController#show

invalid date
Rails.root: /Users/nelsonkeating/Desktop/ReminDeal

Application Trace | Framework Trace | Full Trace
app/controllers/users_controller.rb:13:in `show'
Request

Parameters:

{"month"=>"2012-06",
 "id"=>"7"}

users_controller.rb

def show
    @user = User.find(params[:id])
    @friends = @user.friends.paginate(page: params[:page])
    @date = params[:month] ? Date.parse(params[:month]) : Date.today
   end

安慰：

Answer 1

It is cause due to improper format of the date, the date format is either "%Y-%m-%d" or"%d-%m-%Y" since you have just pass the parameter i.e.
    {"month"=>"2012-06", "id"=>"7"}
you should send the parameter 
    {"month"=>"2012-06-27", "id"=>"7"}
you should send the date also
I had the same problem and solve by adding day in the date parameter.

希望这会帮助你。

是引起错误的Date.parse("2012-06") 。

如果日期不重要，则可以尝试以下操作： Date.parse("#{params[:month]}-01")
