在回形针中使用单个附件进行视频/图像 [英] Use single attachment for video/image in paperclip
本文介绍了在回形针中使用单个附件进行视频/图像的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
对视频和图片使用了相同的附件(来源)。
class Media< ActiveRecord :: Base
belongs_to:memory
validates_attachment_presence:source
validates_attachment_content_type:source,
:content_type => ['video / mp4','image / png','image / jpeg','image / jpg','image / gif']
end
现在我想在不同情况下显示不同的错误信息。
$ b $ ol
我怎样才能做到这一点?
任何帮助将不胜感激。
解决方案
最后我得到了解决方案。
我为相同的
class Media< ActiveRecord :: Base
belongs_to:memory
validates_attachment_presence:source
validates_attachment_content_type:source,
:content_type => ['video / mp4'],
:message => 抱歉,现在我们只支持MP4视频,
:if => :is_type_of_video?
validates_attachment_content_type:source,
:content_type => ['image / png','image / jpeg','image / jpg','image / gif'],
:message => 不同的错误信息,
:if => :is_type_of_image?
has_attached_file:源
保护
def is_type_of_video?
source.content_type =〜%r(video)
end
def is_type_of_image?
source.content_type =〜%r(image)
end
end
I am using paperclip for uploading file ( video and images). Have used the same attachment(source) for both video and images.
class Media < ActiveRecord::Base
belongs_to :memory
validates_attachment_presence :source
validates_attachment_content_type :source,
:content_type => ['video/mp4', 'image/png', 'image/jpeg', 'image/jpg', 'image/gif']
end
Now I wanted to display different error messages in different cases.
- When uploading file is image type but not the jpg/png/jpeg/gif.
- When uploaded file is video type but not the mp4
How can i achieve this ? Any help would highly appreciated.
解决方案
So finally I got the solution. I added 2 conditional validation for the same
class Media < ActiveRecord::Base
belongs_to :memory
validates_attachment_presence :source
validates_attachment_content_type :source,
:content_type => ['video/mp4'],
:message => "Sorry, right now we only support MP4 video",
:if => :is_type_of_video?
validates_attachment_content_type :source,
:content_type => ['image/png', 'image/jpeg', 'image/jpg', 'image/gif'],
:message => "Different error message",
:if => :is_type_of_image?
has_attached_file :source
protected
def is_type_of_video?
source.content_type =~ %r(video)
end
def is_type_of_image?
source.content_type =~ %r(image)
end
end
