How do I add user authentication to Trestle admin?

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.

Trestle vs ActiveAdmin: which is better for Rails?

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.

How to customize the admin dashboard layout in Trestle?

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.

Can Trestle handle large datasets efficiently?

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.

Is Trestle compatible with Rails API-only applications?

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.

How to integrate a markdown editor in Trestle forms?

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.

What is Trestle?

Trestle is a modern, responsive admin framework built for Ruby on Rails applications. It provides a clean, customizable interface for managing application data through a declarative Ruby DSL, solving the need for a flexible and developer-friendly admin panel that integrates seamlessly with Rails conventions.

Target Audience

Ruby on Rails developers and teams who need to build or customize admin interfaces for their applications, particularly those who prefer a Rails-native solution over generic admin generators.

Value Proposition

Developers choose Trestle for its clean DSL, responsive design, and extensible plugin architecture, which allows for highly customized admin interfaces without sacrificing the Rails development experience or requiring heavy frontend frameworks.

Pros & Cons

Pros

Responsive Modern Interface

Provides a clean, mobile-friendly design that works across all devices, as evidenced by the screenshots and description in the README highlighting its modern, responsive framework.

Declarative Ruby DSL

Enables defining admin resources, tables, forms, and navigation using an intuitive Ruby DSL, making it seamless for Rails developers to customize without leaving the Rails ecosystem.

Flexible Layout Customization

Supports organizing forms with tabs, sidebars, and a 12-column grid system, allowing for highly tailored admin interfaces as shown in the example form structure.

Extensible Plugin Ecosystem

Offers official and community plugins for features like authentication, search, and editor integrations, enabling easy extension of functionality beyond the core framework.

Cons

Plugin Dependency for Core Features

Essential admin features such as user authentication are not built-in and require installing separate plugins like trestle-auth, adding complexity and potential maintenance overhead.

Rails-Centric Lock-in

Tightly coupled with Ruby on Rails, making it unsuitable for applications using other backend technologies or frameworks, limiting its versatility.

Learning Curve for DSL

Teams unfamiliar with DSL-based configuration may face a steeper learning curve compared to more conventional admin generators, as customization requires understanding the custom Ruby syntax.
