[英]Add an image next to a checkbox label in activeadmin form
I am using gem 'activeadmin', '~> 1.3' in a rails app. 我在Rails应用程序中使用gem'activeadmin','〜> 1.3'。 I have these relationships between two models :
我在两个模型之间有这些关系:
class Offer < ApplicationRecord
has_many :products
end
class Product < ApplicationRecord
belongs_to :offer, required: false
has_attachments :photos, maximum: 4, dependent: :destroy
end
I can access a product's first photo this way : @product.photos[0]
or @product.photos[0].path
我可以这样访问产品的第一张照片:
@product.photos[0]
或@product.photos[0].path
In admin/offer.rb, the checkboxes to select products belonging to the offer are built with : 在admin / offer.rb中,使用以下选项构建了用于选择属于该商品的产品的复选框:
f.input :products, as: :check_boxes
This renders a checkbox list with product names as labels. 这将显示一个复选框列表,其中包含产品名称作为标签。 Now I want to enrich this label with a thumbnail of one product's photos next to it.
现在,我想在标签旁边加上一个产品的照片缩略图。
I failed to iterate over the ":products" when the checkboxes are built. 构建复选框后,我无法遍历“:products”。 I wanted to add an html tag like this :
span img(src: "product_image_path")
, as I do when I display the product page in activeadmin. 我想添加一个像这样的html标签:
span img(src: "product_image_path")
,就像我在activeadmin中显示产品页面时一样。
I checked formtastic documentation and only found this customization option : :collection => Product.pluck(:name, :id)
. 我检查了表格文档,仅发现此自定义选项
:collection => Product.pluck(:name, :id)
。 This lets me change only the text in label but do not provide me a way to add an image. 这使我只能更改标签中的文本,而不能提供添加图像的方法。
How can I display a thumbnail of one of the product's photos next to product name in activeadmin form ? 如何以activeadmin形式在产品名称旁边显示产品照片之一的缩略图?
As stated in : formtastic documentation , you can customize existing inputs. 如: 格式文档中所述 ,您可以自定义现有输入。 Thus, I created a checkbox_image input in a app/inputs/checkbox_image_input.rb :
因此,我在app / inputs / checkbox_image_input.rb中创建了一个checkbox_image输入:
class CheckboxImageInput < Formtastic::Inputs::CheckBoxesInput
include CloudinaryHelper
def choice_html(choice)
template.content_tag(
:label,
img_tag(choice) + checkbox_input(choice) + choice_label(choice),
label_html_options.merge(:for => choice_input_dom_id(choice), :class =>
"input_with_thumbnail"))
end
def img_tag(choice)
cl_image_tag(Product.find(choice[1]).photos[0].path, :width=>30,
:crop=>"scale")
end
end
I use cloudinary as an image storage service, you can update img_tag(choice) according to yours. 我使用cloudinary作为图像存储服务,您可以根据自己的意愿更新img_tag(choice)。 Then you can use the new input in admin/model.rb, in form :
然后,您可以使用admin / model.rb中的新输入,格式为:
f.input :products, as: :checkbox_image, :collection => product_selection
Enventually I styled the new label tag in my active_admin_custom_css.css file, using input_with_thumbnail class. 无疑,我使用input_with_thumbnail类在active_admin_custom_css.css文件中设置了新标签标签的样式。
