这可能不是最干净的代码，对Ruby来说还是一个新手......
我的message.rb模型中有以下垃圾邮件检查方法：
validate :no_spam?, :if => "sender_user_id != nil"
private
def no_spam?
#first easy spam detection, if the (hidden by css) company field is filled, it is spam for sure
if !company.blank?
errors.add(:body, I18n.t(:No_spam_allowed))
return false
end
#Mollom advanced spam detection
m = Mollom.new(:private_key => 'xxx',
:public_key => 'xxx')
#check content in case it is a first submit of the form
if captcha_session_id.blank?
content = m.check_content(:post_body => body,
:author_name => sender_name,
:author_mail => sender_email,
:author_ip => sender_ip)
else
#check captcha if the form was resumbitted after an unsure result
logger.debug "DEBUG: GOING TO CHECK CAPTCHA"
result = m.valid_captcha?(:session_id => captcha_session_id,
:solution => captcha_solution.chomp)
if result
logger.debug "DEBUG: TRUE -> GOOD CAPTCHA"
return true
else
logger.debug "DEBUG: FALSE -> BAD CAPTCHA"
return false
end
end
#returning the right values and error messages for different content check outcomes
logger.debug "DEBUG: I'M CONTINUING THE METHOD EXECUTION"
if content.spam?
logger.debug "DEBUG: SPAM DETECTED"
errors.add(:body, I18n.t(:No_spam_allowed))
return false
elsif content.unsure?
logger.debug "DEBUG: MESSAGE UNSURE - FAIL FORM BUT SHOW CAPTCHA"
errors.add(:captcha_solution, I18n.t(:Type_the_characters_you_see_in_the_picture_below))
self.captcha_image_url = m.image_captcha(:session_id => content.session_id)["url"]
self.captcha_session_id = content.session_id
return false
else
logger.debug "DEBUG: MESSAGE OK!"
return true
end
end

SQL (3.0ms) COMMIT
在development.log中，您会看到我首先在主体中提交带有'unsure'的表单（第一个创建操作），以调用Mollom的不确定结果（此站点处于开发模式）。
第一次创建操作的验证失败了。
但是当我现在使用空的验证码验证码重新提交表单时，验证方法返回false，但验证没有，因为保存继续并且最后是COMMITTED。
为什么此验证不会失败并中断（回滚）创建操作？
谢谢， 迈克尔
答案 0 :(得分：1)
发现问题。将false返回到验证是不够的。我需要添加一个错误：errors.add（：body，“error message”）。这个错误和return false一起完成了这项工作。
