Carload

This is another dashboard gem for Rails (see Rails Admin, ActiveAdmin and Administrate). Carload tries to reduce the typing when implement a dashboard, but it also allow developer to realize any page view if they like.

DEMO: https://carload-demo.herokuapp.com/carload/dashboard/

Carload tries to handle errors gracely:

Image file upload is also supported with some assumption.

Usage

Run rails g carload:install to mount engine routes, add require statement, initializer, and Dashboard class file.

You can edit the initializer config/initializers/carload.rb for example:

Carload.setup do |config|
  # Set the title that will be displayed on the browser tab area.
  config.page.title = nil

  # Set the footer text that will be displayed on each page.
  config.page.footer = nil

  # Set the colors of page elements.
  config.page.main_color = nil
  config.page.text_color = 'black'
  config.page.button_color = nil
  config.page.button_text_color = nil

  # Specify which authentication solution is used. Currently, we only support Devise.
  config.auth_solution = :devise

  # Set which file upload solution is used. Currently, we only support Carrierwave.
  config.upload_solution = :carrierwave

  # Set the actions used to discern user's permission to access dashboard.
  #
  #   config.dashboard.permits_user.<method> = '...'
  #
  # There are four access methods can be configured:
  #
  #   index, new, edit, destroy
  #
  # Also you can use a special method 'all' to set the default permission.
  # The permission can also be array, the relation among them is OR.
  # By doing this, you have full control on the access permission.
  # TODO: Set the permissions for each data table.
  config.dashboard.permits_user.all = 'role.admin?'
end

Edit app/carload/dashboard.rb to adapt for your needs, for example:

# Dashboard class is used to tell Carload what models are needed to administrated,
# which attributes are shown, etc.

class Dashboard < Carload::Dashboard
  # There are two DSL block types:
  #
  #   model :<model_name> do |spec|
  #     # Whether model should be displayed when URL does not specify one
  #     spec.default = <true_or_false>
  #     # List of attributes that can be edited
  #     spec.attributes.permitted = [...]
  #     # List of attributes that will be shown on index page
  #     spec.index_page.shows.attributes = [...]
  #     # List of attributes with search terms that can be searched on index page (using Ransack gem)
  #     spec.index_page.searches.attributes = [ { name: ..., term: ...}, ... ]
  #   end
  #
  #   associate :<model_name_a> => :<model_name_b>, choose_by: :<attribute_in_model_b>

  model :product do |spec|
    spec.default = true
    spec.attributes.permitted = [ :name ]
    spec.index_page.shows.attributes = [ :name ]
    spec.index_page.searches.attributes = [
      { name: :name, term: :cont }
    ]
  end
  model :item do |spec|
    spec.attributes.permitted = [ :name, :product_id ]
    spec.index_page.shows.attributes = [ :name, 'product.name' ]
    spec.index_page.searches.attributes = [
      { name: :name, term: :cont },
      { name: 'product.name', term: :cont }
    ]
  end
  associate :item => :product, choose_by: :name
end

You can run another generator rails g carload:dash <model_name> to generate the above content automatically (it may ask you some question).
Make sure you have the necessary I18n translation files, for example:

en:
  activerecord:
    models:
      item: Item
    attributes:
      item:
        name: Name
        product:
          name: Product Name

en:
  activerecord:
    models:
      product: Product
    attributes:
      product:
        name: Name
