How to Create a Reusable Button Helper in Ruby on Rails 7

If you're developing a Ruby on Rails 7 application, you'll often find yourself needing to create reusable components for your views. One such component is a button that you use in multiple places across your application. Instead of repeating the same code, you can create a reusable helper method that simplifies your code and makes maintenance easier.

Why Use Helper Methods for Buttons?

Helper methods in Ruby on Rails allow you to keep your views clean, consistent, and DRY (Don't Repeat Yourself). By defining a helper method for a commonly used button, you can:

• Easily change the button's design or behavior in a single place.
• Customize the text, path, and other attributes wherever the button is used.
• Improve readability and maintainability of your code.

Step-by-Step: Creating a Reusable Button Helper

Here's how to create a reusable button helper in Ruby on Rails 7.

Step 1: Open Your Application Helper File

Rails includes a default helper file located at app/helpers/application_helper.rb. Open this file to add your new helper method.

Step 2: Define the Custom Button Helper Method

Add the following method to application_helper.rb:

# app/helpers/application_helper.rb
module ApplicationHelper
  def custom_button(text, path, options = {})
    default_options = {
      class: 'rounded-md bg-teal-800 px-3.5 py-2.5 text-sm font-semibold text-white shadow-sm hover:bg-teal-600 focus-visible:outline focus-visible:outline-2 focus-visible:outline-offset-2 focus-visible:outline-teal-600',
      data: { turbo: false }
    }

    # Merge the default options with any custom options passed in
    link_to text, path, default_options.merge(options)
  end
end

This helper method, custom_button, takes three parameters:

• text: The text displayed on the button.
• path: The URL or route where the button should link.
• options: An optional hash for additional HTML attributes or customization.

The method merges any custom options you pass in with a set of default options, ensuring your button has a consistent style across your application.

Step 3: Use the Helper Method in Your Views

Now, you can use the custom_button helper method anywhere in your views:

<%= custom_button 'Get Started', new_subscription_path %>

The above line creates a button with the text "Get Started" that links to the new_subscription_path. If you want to change the text or add custom options, just pass them like this:

<%= custom_button 'Sign Up Now', new_user_registration_path, class: 'custom-class', data: { turbo: true } %>

This flexibility makes it easy to use the button in various contexts with different labels, paths, and styles.

Benefits of Using a Custom Button Helper

By creating a custom button helper, you:

• Save Time: No need to rewrite button HTML code across multiple views.
• Ensure Consistency: Keep the same button style throughout your application.
• Improve Maintainability: Easily make changes to the button style or behavior in one place.

Conclusion

Using helper methods in Ruby on Rails is a great way to keep your code clean, maintainable, and DRY. By creating a reusable button helper, you can easily manage the appearance and functionality of buttons across your application, enhancing both developer productivity and user experience.

Give this approach a try and see how it can simplify your Rails development!
