Carrierwave未上传 - 显示没有错误 [英] Carrierwave not uploading - no error shown
问题描述
我一直工作在这一夜,这是没有意义的。我适应了老照片的Web应用程序有专辑在里面。我做了失败(基本图像)的专辑嵌套资源。我使用carrierwave将文件上传到S3桶。
I've been working on this all night and it makes no sense. I'm adapting an old photo web app to have albums in it. I made "fails" (basically images) a nested resource of albums. I am using carrierwave to upload files to an S3 bucket.
奇怪的是:上传工作完全正常的相册样板(专辑图片),但它并没有上载故障模型的
我不明白为什么它会成为一个问题,这是一个嵌套的资源了。这是不是显示它是由于某种原因,它通过形式很好,通过验证罚款的问题,不会引发任何错误,它重定向到失败#的索引,比如它是成功的,但并没有什么在DB或S3。
I don't see why it'd be a problem that it's a nested resource now. It's not a problem displaying it's that for some reason, it goes through the form fine, passes validations fine, no errors are thrown, it redirects to fails#index like it was successful, but there is nothing in the db or in S3.

失效模型
class Fail < ActiveRecord::Base
attr_accessible :description, :image, :remote_image_url, :fail_title, :tag_list, :processed, :youtube_url, :album_id
make_voteable
acts_as_taggable
belongs_to :album
mount_uploader :image, ImageUploader
validates :description, length: { :maximum => 200 }
validates :album_id, presence: true
validates :image, presence: true
validates :fail_title, presence: true, length: { :maximum => 50 }
validate :maximum_amount_of_tags
def maximum_amount_of_tags
number_of_tags = tag_list_cache_on("tags").uniq.length
errors.add(:base, "Please only add up to 5 tags") if number_of_tags > 5
end
before_save :update_attachment_attributes
def update_attachment_attributes
if image.present? && image_changed?
self.content_type = image.file.content_type
self.file_size = image.file.size
end
end
def next
user.fails.where("id > ?", id).order("id ASC").first
end
def prev
user.fails.where("id < ?", id).order("id DESC").first
end
end
相册样板
class Album < ActiveRecord::Base
attr_accessible :name, :image, :image_url, :created_at
belongs_to :user
has_many :fails, dependent: :destroy
mount_uploader :image, ImageUploader
validates :user_id, presence: true
validates :image, presence: true
validates :name, presence: true, length: { :maximum => 50 }
before_save :update_attachment_attributes
def update_attachment_attributes
if image.present? && image_changed?
#self.content_type = image.file.content_type
#self.file_size = image.file.size
end
end
def next
user.fails.where("id > ?", id).order("id ASC").first
end
def prev
user.fails.where("id < ?", id).order("id DESC").first
end
end
失败控制器
def new
@fail = Fail.new(:album_id => params[:album_id])
respond_to do |format|
format.html # new.html.erb
format.json { render json: @fail }
end
end
def create
@fail = Fail.new(params[:fail])
respond_to do |format|
if @fail.save
format.html { redirect_to @fail.album, notice: 'You added a new photo!' }
format.json { render json: @fail, status: :created, location: @fail }
else
format.html { render action: "new" }
format.json { render json: @fail.errors, status: :unprocessable_entity }
end
end
end
routes.rb中
routes.rb
resources :albums do
get 'tags/:tag', to: 'fails#index', as: :tag
resources :fails do
member do
post :up_vote
end
end
调试哈希(这会变成红色,当我尝试上传,但是我看不到任何会导致错误)
Debug Hash (this turns red when I try to upload, but I don't see anything that would cause the error)
下面是调试信息:
{"utf8"=>"✓", "authenticity_token"=>"Hz6Gl95ultYDNIEjQioIckB8JXQwhiMxXIM9jrfqd5Q=", "fail"=>{"fail_title"=>"tester", "image"=>#<ActionDispatch::Http::UploadedFile:0x56195e8 @original_filename="pic19.jpg", @content_type="image/jpeg", @headers="Content-Disposition: form-data; name=\"fail[image]\"; filename=\"pic19.jpg\"\r\nContent-Type: image/jpeg\r\n", @tempfile=#<File:C:/Users/Kinertia/AppData/Local/Temp/RackMultipart20131125-10428-m2ktp2>>, "description"=>"", "tag_list"=>"test"}, "commit"=>"Create Fail", "controller"=>"fails", "action"=>"index"}
如果还有什么事需要请让我知道,我会放在这里。谢谢所有帮助!
If there is anything else needed please let me know and I will put it here. Thank you for all the help!
推荐答案
您是否尝试过<一个href="https://github.com/carrierwaveuploader/carrierwave/wiki/How-to%3A-Validate-uploads-with-Active-Record"相对=nofollow>验证失败图片的完整性和处理?
Have you tried validating the integrity or processing of the fail image?
validates_integrity_of :avatar
validates_processing_of :avatar
validates_download_of :avatar
默认情况下它会自动失败,这有点吸。
By default it fails silently, which kinda sucks.
我也建议尝试创建的轨道控制台,它可以帮助找出问题到模型或视图/控制器层的纪录。在你的情况下,这看起来是这样的:
I also recommend trying to create the record in the rails console, which can help to isolate the problem to either the model or view/controller layers. In your case this would look something like:
Fail.create!(
image: File.open('path/to/known/file.jpg'),
album_id: 1,
fail_title: 'Title'
)
