Ruby & Rails Helper-Ruby & Rails code assistance.

Example

Rails' `tag` helper allows you to generate HTML tags dynamically. For instance, `tag.div('Content', class: 'my-class')` produces `<div class='my-class'>Content</div>`.

Scenario

Imagine you need to generate a list of divs with different content and classes within a view template. Instead of hardcoding each div, you can use a loop with the `tag.div` helper to dynamically create the necessary HTML elements, making your view more maintainable.

Example

The `number_to_currency` helper formats a number into a currency string. For instance, `number_to_currency(1234.5)` outputs '$1,234.50'.

Scenario

In a financial application, you need to display prices consistently throughout the site. By using `number_to_currency` in a view helper, you can ensure that all price displays are uniform, following the same format and locale settings.

Example

A custom helper method like `admin?` could return true if the current user has admin privileges. `admin?` could be used in a view to show or hide certain elements, such as an admin dashboard link.

Scenario

In a multi-role web application, you might want to conditionally render parts of the UI based on user roles. For example, only administrators should see certain controls or links. A custom helper that checks the user's role can be used in views to hide or display these UI elements, keeping the views clean and role-specific logic centralized.
