我收到错误:
参数数量错误(2 比 1)
在我的Task
模型上,当我定义我的方法来更新任务的所有状态时。什么是正确的语法?
class Task < ActiveRecord::Base
belongs_to :user
def self.toggle(user, groups)
groups.each do |status, ids|
user.tasks.update_all({status: status.to_s}, {id: ids}) #=> error here
end
end
end
class GroupIdsByStatus
def self.group(options = {})
result = Hash.new {|h,k| h[k] = []}
options.reduce(result) do |buffer, (id, status)|
buffer[status.to_sym] << id
buffer
end
result
end
end
class TasksController < ApplicationController
def toggle
groups = GroupIdsByStatus.group(params[:tasks])
Task.toggle(current_user, groups)
redirect_to tasks_path
end
end
