允許用戶繞過創建圖庫上傳照片

Question

我有一個社交網絡，我正在使用載波。我需要設置它的幫助，以便用戶不必創建圖片庫名稱來上傳照片。這是carrierwave的默認設置，但由於這是一個社交網絡，我不允許用戶擁有不同的畫廊（或專輯）。應該只有一個鏈接將照片上傳到他們的個人資料。那麼我該如何攻擊呢？順便說一句，我是新來的Rails，所以任何和所有的幫助將不勝感激！

照片控制器：

def new 
    @photo = Photo.new(:gallery_id => params[:gallery_id]) 
    end 

    def create 
    @photo = Photo.new(params[:photo]) 
    if @photo.save 
     flash[:notice] = "Successfully created photos." 
     redirect_to @photo.gallery 
    else 
     render :action => 'new' 
    end 
end 

    def edit 
    @photo = Photo.find(params[:id]) 
    end 

    def update 
    @photo = Photo.find(params[:id]) 
    if @photo.update_attributes(paramas[:photo]) 
     flash[:notice] = "Successfully updated photo." 
     redirect_to @photo.gallery 
    else 
     render :action => 'edit' 
    end 
    end 

    def destroy 
    @photo = Photo.find(params[:id]) 
    @photo.destroy 
    flash[:notice] = "Successfully destroyed photo." 
    redirect_to @photo.gallery 
    end 
end 

畫廊控制器：

def index 
    @galleries = Gallery.all 
    end 

    def show 
    @gallery = Gallery.find(params[:id]) 
    end 

    def new 
    @gallery = Gallery.new 
    end 

    def create 
    @gallery = Gallery.new(params[:gallery]) 
    if @gallery.save 
     flash[:notice] = "Successfully created gallery." 
     redirect_to @gallery 
    else 
     render :action => 'new' 
    end 
    end 

    def edit 
    @gallery = Gallery.find(params[:id]) 
    end 

    def update 
    @gallery = Gallery.find(params[:id]) 
    if @gallery.update_attributes(params[:gallery]) 
     flash[:notice] = "Successfully updated gallery." 
     redirect_to gallery_url 
    else 
     render :action => 'edit' 
    end 
    end 

    def destroy 
    @gallery = Gallery.find(params[:id]) 
    @gallery.destroy 
    flash[:notice] = "Successfully destroy gallery." 
    redirect_to galleries_url 
    end 
end 

路線：

Dating::Application.routes.draw do 
    get 'signup' => 'users#new' 
    get 'login' => 'sessions#new' 
    get 'logout' => 'sessions#destroy' 
    get 'edit' => 'users#edit' 
    get "/profile/:id" => "users#show" 
    get "profile/:id/settings" => 'users#edit' 
    match 'settings/:id' => 'users#settings' 

    resources :users 
    resources :sessions 
    resources :password_resets 
    resources :galleries 
    resources :photos 
    resources :searches 

    resources :users do 
     get 'settings', on: :member 
    end 

    root to: 'users#new' 
    root to: 'galleries#index' 

    resources :users do |user| 
    resources :messages do 
     collection do 
     post 'delete_multiple' 
     end 
    end 
    end

zwippie的答案是一個很好的選擇，因爲據我可以看到。

如果按照zwippie's答案，你必須修改你的照片控制器，例如像follwoing：

def new 
    @photo = Photo.new 
end 

def create 
    @photo = Photo.new(params[:photo]) 
    @photo.gallery = current_user.gallery 
    if @photo.save 
    flash[:notice] = "Successfully created photos." 
    redirect_to gallery_path @photo.gallery 
    else 
    render :action => 'new' 
    end 
end 

的完全另一種選擇是不產生任何畫廊，只是當前用戶關聯到的照片。

用戶模型：

class User < ActiveRecord::Base 
    has_many :photos 
end 

class Photos < ActiveRecord::Base 
    belongs_to :user 
end 

photos_controller

def new 
    @photo = Photo.new 
end 

def create 
    @photo = Photo.new(params[:photo]) 
    @photo.user = current_user 
    if @photo.save 
    flash[:notice] = "Successfully created photos." 
    redirect_to user_photos_path(current_user) 
    else 
    render :action => 'new' 
    end 
end 

至於你carrierwave設置，您可以選擇例如當前用戶的用戶名，或別的東西畫廊的名字。

UPDATE：改變重定向路徑

你的路線應該像下面：

resources :users do 
    resources :photos 
end 

Answer 2

爲什麼不創建用戶簽約後直接畫廊？或者當用戶上傳第一張照片時創建它。

photos_controller：

def new 
    # Get the gallery for the current user (assuming Gallery has attribute user_id) 
    @gallery = current_user.gallery 

    # Create a new gallery if user does not have one already 
    @gallery = Gallery.create(:user_id => current_user.id) if @gallery.nil? 

    # Save the photo 
    @photo = Photo.new(:gallery_id => @gallery.id) 
end

您可以使用回形針創建畫冊，這裏是鏈接回形針寶石：
