Instance Method Details

#only_on_error_page(*args) ⇒ Object

Execute a block only on error pages.

The error pages are special, because they are the only pages that currently require multiple bindings. We get those from exceptions.

end

#only_on_regular_page(*args) ⇒ Object

Execute a block only on regular, non-error, pages.

#render ⇒ Object

Custom ActionView::Base#render wrapper which silences all the log printings.

Helps to keep the Rails logs clean during errors.

  if (logger = WebConsole.logger) && logger.respond_to?(:silence)
    WebConsole.logger.silence { super }
  else
    super
  end
end

#render_inlined_string(template) ⇒ Object

Render inlined string to be used inside of JavaScript code.

The inlined string is returned as an actual JavaScript string. You don’t need to wrap the result yourself.

# File 'lib/web_console/view.rb', line 33

def render_inlined_string(template)
  render(template: template, layout: "layouts/inlined_string")
end

#render_javascript(template) ⇒ Object

Render JavaScript inside a script tag and a closure.

This one lets write JavaScript that will automatically get wrapped in a script tag and enclosed in a closure, so you don’t have to worry for leaking globals, unless you explicitly want to.

def render_javascript(template)
  assign(template: template)
  assign(nonce: @env["action_dispatch.content_security_policy_nonce"])
  render(template: template, layout: "layouts/javascript")
end

#t(key, options = {}) ⇒ Object

Override method for ActionView::Helpers::TranslationHelper#t.

This method escapes the original return value for JavaScript, since the method returns a HTML tag with some attributes when the key is not found, so it could cause a syntax error if we use the value in the string literals.
