Class Method Details

.render(template_path, locals = {}) ⇒ String

Shortcut method for rendering templates This method provides a convenient interface to render ERB templates directly from the Stellar::Erb module without instantiating a View.

Examples:

Render a template with variables

Stellar::Erb.render("path/to/template.erb", name: "World")

Render a template without variables

Stellar::Erb.render("path/to/simple.erb")

Parameters:

  • template_path (String) —

    The path to the ERB template file

  • locals (Hash) (defaults to: {}) —

    A hash of local variables to be made available in the template

Returns:

  • (String) —

    The rendered template result

Raises:

  • (Stellar::Erb::Error) —

    if an error occurs during template rendering

  • (Errno::ENOENT) —

    if the template file doesn’t exist

def self.render(template_path, locals = {})
  View.render(template_path, locals)
end

.render_string(str, locals = {}) ⇒ String

Renders an ERB template from a string instead of a file This is useful for template strings that are generated dynamically or stored in a database rather than in files.

Examples:

Render a string template with variables

Stellar::Erb.render_string("<p>Hello, <%= name %></p>", name: "World")

Render a string template without variables

Stellar::Erb.render_string("<p>Static content</p>")

Parameters:

  • str (String) —

    The ERB template string to render

  • locals (Hash) (defaults to: {}) —

    A hash of local variables to be made available in the template

Returns:

  • (String) —

    The rendered template result

Raises:
