ruby-on-rails – 如何通过Paperclip rails上传图像,word文档和/或PDF文件4

我想让用户将Word文档和PDF文件上传到我的rails应用程序.我的应用程序类似于Pinterest应用程序,用户可以在其附加图片的同时创建引脚,然后再进行说明(使用“纸张剪贴板将图像附加到引脚”).

这是我的引脚模型：

class Pin < ActiveRecord::Base
    belongs_to :user
    has_attached_file :image,:styles => { :medium => "300x300>",:thumb => "100x100>" }
    validates_attachment :image,content_type: { content_type: ["image/jpg","image/jpeg","image/png","image/gif"] }
    validates :image,presence: true
 
    end

我的引脚控制器：

class PinsController < ApplicationController
  before_action :set_pin,only: [:show,:edit,:update,:destroy]
  before_action :correct_user,only: [:edit,:destroy]
  before_action :authenticate_user!,except: [:index,:show]
 
  def index
    @pins = Pin.all.order("created_at DESC").paginate(:page => params[:page],:per_page => 15)
  end
 
  def show
  end
 
  def new
    @pin = current_user.pins.build
  end
 
  def edit
  end
 
 def create
    @pin = current_user.pins.build(pin_params)
    if @pin.save
      redirect_to @pin,notice: 'Pin was successfully created.'
    else
      render action: 'new'
    end
  end
 
  def update
    if @pin.update(pin_params)
      redirect_to @pin,notice: 'Pin was successfully updated.'
    else
      render action: 'edit'
    end
  end
 
  def destroy
    @pin.destroy
    redirect_to pins_url
  end
 
  private
 
    def set_pin
      @pin = Pin.find(params[:id])
    end
 
    def correct_user
      @pin = current_user.pins.find_by(id: params[:id] )
      redirect_to pins_path,notice: "Not authorized to edit this Pin" if @pin.nil?
    end
 
 
    def pin_params
      params.require(:pin).permit(:description,:image)
    end
end

我想知道我是否需要为我的Pin模型中的Word文档和PDF文件创建另一个has_attached_file方法,然后为用户创建一个用于上传文件的视图.

解决方法

这取决于…

如果要附加图像和文档,则需要为文档创建另一个纸张剪贴画属性.您的型号：

has_attached_file :image,:thumb => "100x100>" }
validates_attachment :image,"image/gif"] }
 
has_attached_file :document
validates_attachment :document,:content_type => { :content_type => %w(application/pdf application/msword application/vnd.openxmlformats-officedocument.wordprocessingml.document) }

如果要附加图像或文档,您可以执行以下操作：

has_attached_file :document
validates_attachment :document,:content_type => {:content_type => %w(image/jpeg image/jpg image/png application/pdf application/msword application/vnd.openxmlformats-officedocument.wordprocessingml.document)}

如果您选择第一个选项,则您的视图中将需要两个文件输入,仅第二个选项.这不对还是错.这取决于你想做什么
