Custom list fields as HTML tags

You can customise list view fields as HTML tags, to replace their defaults with links or images. This saves having to create an entire partial just for a single field.

An example of a link tag showing User.name and linking to the user model within rails admin:

field :name do
  pretty_value do
    path = bindings[:view].show_path(model_name: 'User', id: bindings[:object].id)
    bindings[:view].content_tag(:a, bindings[:object].name, href: path)
  end
end

An example of an image field:

field :image do
  pretty_value do
    bindings[:view].tag(:img, { :src => bindings[:object].image.url })
  end
end
