Question 1

How do I add user authentication to Trestle admin?

Accepted Answer

You need to install the trestle-auth plugin. Add 'gem trestle-auth' to your Gemfile, run bundle install, and use the provided generators to set up authentication, as detailed in the plugin's GitHub repository.

Question 2

Trestle vs ActiveAdmin: which is better for Rails?

Accepted Answer

Trestle offers a more modern interface and cleaner DSL, while ActiveAdmin has more built-in features and a larger ecosystem. Choose Trestle for customization and Rails-native feel, or ActiveAdmin for quicker setup with less initial coding.

Question 3

How to customize the admin dashboard layout in Trestle?

Accepted Answer

Customize by editing the admin resource files in app/admin/ using the DSL. The README example shows how to define tabs, sidebars, and grid-based layouts for forms, allowing flexible arrangement of fields.

Question 4

Can Trestle handle large datasets efficiently?

Accepted Answer

Performance relies on your Rails and database setup. Trestle itself doesn't add significant overhead, but for large datasets, implement pagination and custom queries in the DSL to optimize, as it doesn't include advanced caching out-of-the-box.

Question 5

Is Trestle compatible with Rails API-only applications?

Accepted Answer

Trestle is designed for traditional Rails applications with views and assets. It may not work seamlessly with API-only mode without additional configuration to serve the admin interface, potentially requiring extra setup.

Question 6

How to integrate a markdown editor in Trestle forms?

Accepted Answer

Use the trestle-simplemde plugin. Add the gem to your Gemfile, and then you can use the editor field type in your form DSL, as demonstrated in the example for the body field with custom form fields.
