Ruby on Rails回形针+ Dropbox + Heroku问题

Question

I have small project which works locally like a charm, but adding anything with paperclip doesn't work on heroku and also travis is failing the tests because it cant seem to be able to create user. I have no idea whats wrong I have tried everything but I cannot get the images to upload except locally. I have understood that "User model missing required attr_accessor for 'avatar_file_name' " from the heroku logs might be the problem but I dont know what to do with that. Googling has only suggested heroku db migrate and reset and stuff but none of that has helped. Any help is greatly appreciated!

Here is my code and heroku logs:

User

class User < ActiveRecord::Base
  has_secure_password

  has_attached_file :avatar, :styles => { :thumb => "100x100#" },
                    :storage => :dropbox,
                    :dropbox_credentials => Rails.root.join("config/dropbox.yml"),
                    :dropbox_options => {},
                    :path => ":style/:id_:filename"


  validates_attachment_content_type :avatar, :content_type => /\Aimage/


  validates :username, uniqueness: true,
            length: { minimum: 3, maximum: 15 }

  validates :password, :format => {:with => /(?=.*[a-z])(?=.*[A-Z])(?=.*[0-9]).{4,}/,
                                   message: "Password must be at least 4 characters and include one number and one letter."}


  has_many :images
  has_many :videos
  has_many :comments, dependent: :destroy
end

Image class:

class Image < ActiveRecord::Base
  has_attached_file :photo, :styles => { :small => "100x100#", :thumb => "200x200#" },
                    :storage => :dropbox,
                    :dropbox_credentials => Rails.root.join("config/dropbox.yml"),
                    :dropbox_options => {},
                    :path => ":style/:id_:filename"

  validates_attachment_content_type :photo, :content_type => /\Aimage/

  validates_attachment_presence :photo

  validates :name, presence: true,
            length: { minimum: 3, maximum: 25 }

  validates :description, presence: true,
            length: { minimum: 3}


  belongs_to :user
  has_many :comments, dependent: :destroy
  has_many :users, through: :comments

  def to_s
    self.name
  end
end

Schema:

  create_table "images", force: true do |t|
    t.string   "name"
    t.text     "description"
    t.datetime "created_at"
    t.datetime "updated_at"
    t.string   "photo_file_name"
    t.string   "photo_content_type"
    t.integer  "photo_file_size"
    t.datetime "photo_updated_at"
    t.integer  "user_id"
  end

  create_table "users", force: true do |t|
    t.string   "username"
    t.datetime "created_at"
    t.datetime "updated_at"
    t.string   "password_digest"
    t.string   "avatar_file_name"
    t.string   "avatar_content_type"
    t.integer  "avatar_file_size"

  end

Here are controller creates:

def create
    @user = User.new(user_params)
    respond_to do |format|
      if @user.save
        format.html { redirect_to @user, notice: 'User was successfully created.' }
        format.json { render action: 'show', status: :created, location: @user }
      else
        format.html { render action: 'new' }
        format.json { render json: @user.errors, status: :unprocessable_entity }
      end
    end
  end

def user_params
    params.require(:user).permit(:username, :password, :password_confirmation, :avatar)
end

def create
    @image = Image.new(image_params)

    respond_to do |format|
      if @image.save
        current_user.images << @image
        format.html { redirect_to @image, notice: 'Image was successfully submitted.' }
        format.json { render action: 'show', status: :created, location: @image }
      else
        format.html { render action: 'new' }
        format.json { render json: @image.errors, status: :unprocessable_entity }
      end
    end
  end

def image_params
      params.require(:image).permit(:name, :description, :photo)
end

Answer 1

Since an image belongs_to a user, you need to specify that when you create an image with something along the lines of

def create
   @image = current_user.images.build(image_params)
   ... 
end

and before you decided to deploy it to Heroku, you should test that everything works in your development environment. When you create an Image, either through the rails console or in your view, check what the user_id is: ie- check whether or not it's being associated with a user.

Answer 2

What version of rails are you using?

You may need to add

attr_accessible :avatar_file_name, :avatar_file_size...

...etc to your user model. I seem to recall having a similar problem, and something like:

attr_accessor :avatar_file_name

Did the trick. Heroku and Paperclip can be kind of a pain to debug because of the barriers between you and the server, but keep at it! Let me know if either of those solutions works or at least changes the error you're receiving.
