使用 date_field_tag 防止输入上一个日期 [英] Prevent Input of previous Date with date_field_tag

问题描述

Rails 4 FormTagHelper date_field_tag 是否有一个选项允许我阻止用户选择当前日期之前的日期?

Is there an option with the Rails 4 FormTagHelper date_field_tag which allows me to prevent users from selecting a date previous to the current?

推荐答案

好吧，检查文档 date_field_tag 的语法如下:

Well, checking the documentation the sintax for date_field_tag is the following:

datetime_field_tag(name, value = nil, options = {})

datetime_field_tag(name, value = nil, options = {})

选项接受诸如 (:min, :max) 之类的参数

The options accepts arguments such as (:min, :max)

我不喜欢 Rails4，但您可能可以声明一个保存当前日期的变量，然后将其作为 ':min' 参数的值传递，例如:

Im not fond of Rails4, but you could probably declare a variable that holds the current day date and then pass it as a value for the ':min' argument, something like:

datetime_field_tag(name, value = nil, options = {:min=> @todayvariable})
