我有一个带有验证的模型,我发现如果不先验证对象就无法更新属性。
我已经尝试on => :create
在每个验证行的末尾添加语法,但是得到的结果相同。
我的公告模型具有以下验证:
validates_presence_of :title
validates_presence_of :description
validates_presence_of :announcement_type_id
validate :validates_publication_date
validate :validates_start_date
validate :validates_start_end_dates
validate :validates_category
validate :validates_province
validates_length_of :title, :in => 6..255, :on => :save
validates_length_of :subtitle, :in => 0..255, :on => :save
validates_length_of :subtitle, :in => 0..255, :on => :save
validates_length_of :place, :in => 0..50, :on => :save
validates_numericality_of :vacants, :greater_than_or_equal_to => 0, :only_integer => true
validates_numericality_of :price, :greater_than_or_equal_to => 0, :only_integer => true
我的瑞克任务执行以下操作:
task :announcements_expiration => :environment do
announcements = Announcement.expired
announcements.each do |a|
#Gets the user that owns the announcement
user = User.find(a.user_id)
puts a.title + '...'
a.state = 'deactivated'
if a.update_attributes(:state => a.state)
puts 'state changed to deactivated'
else
a.errors.each do |e|
puts e
end
end
end
这将在输出中抛出该模型的所有验证异常。
是否有人在不验证模型的情况下如何更新属性?
