ruby-on-rails – 如何使用simple_form在datetime字段中仅设置小

发布时间：2020-12-16 21:00:58 所属栏目：百科来源：网络整理

导读：我想从select_box中选择一小时(10,11,12,13,14,15),并从params [：call_date]中选择日期 # params[:call_date] = "2013-11-05"= simple_form_for @welcome_call do |f| = f.input :call_at,as: :datetime = f.association :user,collection: User.all = f.su

我想从select_box中选择一小时(10,11,12,13,14,15),并从params [：call_date]中选择日期

# params[:call_date] => "2013-11-05"
= simple_form_for @welcome_call do |f|
  = f.input :call_at,as: :datetime
  = f.association :user,collection: User.all
  = f.submit

解决方法

也许这个？ (我不确定：call_at选择框的语法)

# params[:call_date] => "2013-11-05"
= simple_form_for @welcome_call do |f|
  = f.input :call_at,as: :select,collection: (10..15)
  = f.association :user,collection: User.all
  = f.submit

# in controller:
date = Date.parse(params[:call_date])
date_time = DateTime.new(date.year,date.month,date.mday,params[:call_at].to_f,0)
