在Ruby on Rails中使用回形针Gem将所有输入字段转换为按钮

paperclip ruby ruby-on-rails

Charles Smith · 技术社区 · 7 年前

我正在进行我的第一个Rails项目,并安装了 Paperclip Gem 处理图像上传。按原样,它工作正常,但所有上传字段都显示为单独填写,如下面的屏幕截图所示。

模型/项目.rb

class Project < ApplicationRecord
  has_many :tasks

  validates :name, presence: true, length: { maximum: 50 }
  validates :content, presence: true, length: { maximum: 500 }
  validates :price, presence: true, numericality: { only_integer: true }

  has_attached_file :avatar, styles: { medium: '680x300>', thumb: '170x75>' }, default_url: '/images/:style/missing.png"'
  validates_attachment_content_type :avatar, content_type: '/\Aimage\/.*\z/'
end

ActiveAdmin.register Project do
  permit_params :name, :content, :price, :image

  show do |t|
    attributes_table do
      row :name
      row :content
      row :price
      row :image do
        project.image? ? image_tag(project.image.url, height: '100') : content_tag(:span, 'No Photo Yet')
      end
    end
  end

  # form html: { enctype: 'multipart/form-data' } do |f|
  #   f.input do
  #     f.input :name
  #     f.input :content
  #     f.input :price
  #     f.input :image, hint: f.project.image? ? image_tag(project.image.url, height: '100') : content_tag(:span, 'Upload JPG/PNG/GIF Image')
  #   end
  #   f.actions
  # end
end

admin/project.rb 密码

我正在使用ActiveAdmin、回形针5.1和Rails 5.1.1

我看到你的表格需要做一些修改。

目前看起来像:

form html: { enctype: 'multipart/form-data' } do |f|
  f.input do
    f.input :name
    f.input :content
    f.input :price
    f.input :image, hint: f.project.image? ? image_tag(project.image.url, height: '100') : content_tag(:span, 'Upload JPG/PNG/GIF Image')
  end
  f.actions
end

它应该看起来像:

form html: { enctype: 'multipart/form-data' } do |f|
  f.inputs do
    f.input :name
    f.input :content
    f.input :price
    f.input :image, hint: resource.project.image? ? image_tag(project.image.url, height: '100') : content_tag(:span, 'Upload JPG/PNG/GIF Image')
  end
  f.actions
end

input inputs ,在阅读了ActiveAdmin关于 forms f.project.image? 到 resource.project.image? resource 与您的 Project
