Question

希望你能帮助我解决我目前遇到的问题。

我已设置Paperclip以帮助我上传图片，并在按照说明操作并查看各种指南后，我认为它应该正常工作，但我遇到的问题是它的问题根本不保存图像并显示以下错误。有人能指出学习者朝着正确的方向前进吗？

我已经使用imagemagick通过命令行进行转换而没有任何问题。

更新：我刚刚查看了我的文件，发现我已按照文档中的要求添加了此文件。我是否需要修改：command_path

更新2 ：我现在已经解决了这个问题，我的解决方案就是答案部分。

Paperclip.options[:command_path] = "/usr/local/bin/"

There was an error processing the thumbnail for f87ef1d19d0a3693810436f1278205e020150803-666-1avrc9e

提取的来源如下：

def create
admin = Admin.new(admin_params)

if admin.save
  redirect_to '/administration'

参数

型号（admin.rb）

class Admin < ActiveRecord::Base
has_secure_password

has_attached_file :avatar, :styles => {
    :medium => "300x300>",
    :thumb => "50x50#>"},
    :default_url => "/images/:style/missing.png"
validates_attachment_content_type :avatar, :content_type => /\Aimage\/.*\Z/
end

管理控制器

 class AdminController < ApplicationController
def new
end

def create
admin = Admin.new(admin_params)

if admin.save
  redirect_to '/administration'
  flash[:success] = "Admin account created successfully"
else
    flash[:error] = "Unable to create account"
  render 'administration/new_ai_admin'
end
end

private

def admin_params
params.require(:admin).permit(:name, :email, :user_name, :password, :password_confirmation, :avatar)
end
end

Answer 1

尝试使用Rails迁移生成器：

rails generate paperclip admin avatar

Answer 2

我终于设法解决了这个问题，这只是模型中错误类型的情况。这是我的工作管理模型

<强> admin.rb class Admin＆lt;的ActiveRecord :: Base的 has_secure_password

 describe('Employee test', function () {
    beforeEach(() => {
        module('app');
        inject((_$controller_: ng.IControllerService, _$httpBackend_: ng.IHttpBackendService, $http: ng.IHttpService) => {

                httpB = _$httpBackend_;
                http = $http;
                empService = new EmployeeService($http);

                ctrl = $controller("employeeCtrl", { $scope: $scope, empService });
        });
    it("controller constructor",() => {
                empService.testdata = [];
                var ctrlObj = new employeeCtrlClass($scope, empService);
        });
     });

使用PaperClip在轨道
