Rails | ActiveAdmin |Custom checkboxes collection for array field

Sometimes you might want to store coherent information in single string field in database. For such fields you might want the Admin to have some mechanism to update.

In Rails you can have Array field like

# in migration file
# Array Types
t.string :open_days,       array: true, default: []
t.string :payment_options, array: true, default: []
t.text   :vehicle_vendors, array: true, default: []
t.text   :services_ids,    array: true, default: []

for such fields the form builder would look like Continue reading

Rails : Customize Rails Admin engine

I wondered what these terms like collection and member mean.

member :activate do
  only ['Contractor']
  i18n_key :activate
end

collection :painter_photos do
  i18n_key :painter_photos
end

member: These are actions applicable to individual records in the model. This will show up in every row like.

collection: applicable to the model as a whole

How to add custom action in particular row?

member :activate do
  only ['Contractor']
  i18n_key :activate
end

for this you would need to put

# in views/rails_admin/main/activate.haml
- if @object.is_a?(Contractor)
  - if @object.active?
    %p Already Activated
  - else
    %p You are about to activate a contractor.
    %p
      Name:
      %b
        = @object.full_name
    = link_to "Activate Contractor", main_app.admin_activate_contractor_path(@object), confirm: "Are you sure?", class: "btn"
- else
  %p Sorry, only contractors can be activated.

and

# in rails_admin.en.yml
activate:
  title: "Activate"
  menu: "Activate"
  breadcrumb: "Activate"

 

Custom Label

field :painters, :boolean do
  label do
    "Send to all contractors"
  end

  render do
    content =  bindings[:form].check_box :painters
    bindings[:view].render inline: content
  end
end

Customize the Edit / New Form

You can customize the button names in the form but in a tricky way. For example lets try to change the button names like Save to Send and so.

copy the file

https://github.com/sferik/…/_submit_buttons.html.haml this page in your repo at “views/rails_admin/main/_submit_button.html.haml”

and put conditional like

- if params['model_name']  == 'broadcast' && params['action'] == 'new'
  %button.btn.btn-primary{type: "submit", name: "_save", :'data-disable-with' => t("admin.models.broadcast.save")}
    %i.icon-white.icon-email
    = t('admin.models.broadcast.save')
- else
  %button.btn.btn-primary{type: "submit", name: "_save", :'data-disable-with' => t("admin.form.save")}
    %i.icon-white.icon-ok
    = t("admin.form.save")

and add some i18n keys in rails_admin.en.yml like

en:
  admin:
    loading: "Loading..."
    home:
      name: "Home"
    pagination:
      previous: "« Prev"
      next: "Next »"
      truncate: "…"
    models:
      broadcast:
        save: 'Send Message'
        save_and_add_another: 'Send and prepare for next'
        save_and_edit: 'Send and Edit'
