我有一个表格,用户可以输入日期(例如03/18/2014):
= f.text_field :purchase_date, class: "form-control", placeholder: "mm/dd/yyyy"
当用户提交新Inventory
对象的表单时,我在创建操作中不断收到错误argument out of range
。但是,如果我已经有一个现有的对象,并且我尝试更新它,它可以正常工作。奇怪的是,我的看跌期权并没有在服务器日志中输出任何内容。
def create
puts "CREATE" # this line is not outputting anything
purchase_date = inventory_params["purchase_date"].blank? ? Date.today : Date::strptime(inventory_params["purchase_date"], "%m/%d/%Y")
@inventory = Inventory.create( name: inventory_params["name"],
purchase_price: purchase_price,
purchase_date: purchase_date,
serial: inventory_params["serial"].to_s,
description: inventory_params["description"].to_s,
product_type: inventory_params["product_type"].to_s,
current_location: inventory_params["current_location"].to_s,
vendor_id: inventory_params["vendor_id"],
team_id: current_team.id)
redirect_to inventories_path
end
def update
purchase_date = inventory_params["purchase_date"].blank? ? Date.today : Date::strptime(inventory_params["purchase_date"], "%m/%d/%Y")
@inventory.update_attributes( name: inventory_params["name"],
purchase_price: purchase_price,
purchase_date: purchase_date,
serial: inventory_params["serial"],
description: inventory_params["description"],
product_type: inventory_params["product_type"],
current_location: inventory_params["current_location"],
vendor_id: inventory_params["vendor_id"]
)
redirect_to inventory_path(@inventory)
end
private
def inventory_params
params.require(:inventory).permit(:purchase_price, :purchase_date, :name, :serial, :description, :product_type, :current_location, :vendor_id)
end
我也设置了CanCan,但我认为它不会影响它:
class Ability
include CanCan::Ability
def initialize(user)
user ||= User.new # guest user (not logged in)
can [:create, :show, :destroy, :edit, :update], User, id: user.id
can :create, Inventory
can [:index, :show, :destroy, :edit, :update], Inventory do |inventory|
user && (inventory.try(:team_id) == user.teams.first.id)
end
end
end
当我尝试创建Inventory
的新实例时,有谁知道为什么我会一直收到异常?
更新:如果我的日期使用两位数,它就会中断。例如,3/1/2014
有效,但3/11/2014
会中断......

下次你只需要少写几行。你写的内容相当于@inventory =
Inventory.create(inventory_params.merge({team_id: current_team.id}))
和
@inventory.update_attributes(inventory_params)
另外,我发现你的错误,你写的是03/18/14(那意味着2003-18-14),没有18个月! 它不是用法语标准写的:)
顺便说一下,如果你需要使用法语(或类似)标准:请阅读 http://guides.rubyonrails.org/i18n.html
并在那里下载必要的文件: https://github.com/svenfuchs/rails-i18n/blob/master/rails/locale/fr.yml

Cancan打破了Rails 4.0。 这解决了这个问题:
load_and_authorize_resource :except => [:create]
