FAQ

Q: How to set the Favicon?

A: In config/initializers/trestle.rb set config.favicon = "favicon.ico"

Q: How to rename the title of a resource view?

A: In config/locales/en.yml set en.admin.<model>.titles.index (see issue). For instance if you model is called AuthorityCard:

# config/locales/en.yml
en:
  admin:
     authority_cards:
        breadcrumbs:
          index: "Authority Cards"
        titles:
          index: "List of Authority cards"

Q: How can I remove the Add / Delete Buttons?

A: You can remove default actions (e.g. create, destroy) from a resource like so:

Trestle.resource(:articles) do
  remove_action :destroy

This will result in the delete button no longer being present on the index or show pages.

Note that if you want to remove the "New resource" button to prevent resources from being created, you should remove both :new and :create:

Trestle.resource(:articles) do
  remove_action :new, :create

Q: How can I link back to a model in the main app?

A: If you need to create a button that brings you to the resource in the "frontend" using the Rails routes you can use the follow (given model is your admin instance):

/app/admin/model_admin.rb

  unless model.new_record?
    concat content_tag(:hr)
    concat link_to("Preview", Rails.application.routes.url_helpers.model_path(model), class: "btn btn-primary", target: :_blank)
  end
