Overview
Monkeypatch to allow mailer to auto generate text/html
If you generate a mailer action, by default it will only render an html email:
def welcome
mail(
to: "[email protected]",
reply_to: "[email protected]",
subject: "hello world"
)
end
You can add a format block to have it produce html and text emails:
def welcome
mail(
to: "[email protected]",
reply_to: "[email protected]",
subject: "hello world"
) do |format|
format.text
format.html
end
end
For the handler to work correctly and produce both HTML and text emails this would need to be required similar to how github.com/plataformatec/markerb works.
This monkeypatch detects when a markdown email is being used and generates both a markdown and text template
