作物不會與設計和導軌4作者：

我試圖結合設計，papercrop，回形針，使用戶可以裁剪和更新頭像。圖像完美地更新給用戶，但不會裁剪。我通過作物行動和視圖傳遞它。但它不會裁剪或無論如何顯示它。作物不會與設計和導軌4作者：

User.rb

class User < ActiveRecord::Base 
    # Include default devise modules. Others available are: 
    # :confirmable, :lockable, :timeoutable and :omniauthable 
    devise :database_authenticatable, :registerable, 
     :recoverable, :rememberable, :trackable, :validatable 

    has_attached_file :avatar, :styles => {:thumb => '50x50', :medium => '400x300'}, 
              :default_url => "/images/:style/missing.png" 
    validates_attachment_content_type :avatar, :content_type => /\Aimage\/.*\Z/ 
    crop_attached_file :avatar, :aspect => "16:9" 

end

Registrations_controller.rb

class Users::RegistrationsController < Devise::RegistrationsController 

    def new 
     super # no customization, simply call the devise implementation 
    end 

def update 

    if params[resource_name][:avatar].blank? 
     super 


    elsif params[:user][:email].blank? && params[:user][:password].blank? && params[:user][:password_confirmation].blank? && params[:user][:current_password].blank? 
     flash[:notice] = "Successfully updated user." 
     redirect_to @user 
    else 

      @user = User.find(current_user.id) 
     respond_to do |format| 
     if resource.update_attributes(params[resource_name].permit(:avatar)) 
      flash[:notice]='Avatar successfully uploaded.' 
      format.html { 
        render :action => 'crop' 
      } 
      format.xml { head :ok } 
      else 
      format.html { render :action => "editpicture" } 
      format.xml { render :xml => @demotivator.errors, :status => :unprocessable_entity }

請將您的視圖中的代碼發佈到顯示圖像的地方。 – Agis

@Agis立即更新... – Petter

在您的視圖中看到的文件的實際大小是多少？請注意，在裁剪時，您提供了*長寬比*。 – Agis

Papercrop不與Turbolinks寶石工作。通過在<body>標記中添加"data-no-turbolink"來禁用頁面上的Turbolink。
