#4004 ✓duplicate

default_url_options is a missing method

Reported by Damien MATHIEU | February 19th, 2010 @ 04:00 PM

The ActionMailer::Base's documentation says we should use

config.action_mailer.default_url_options = { :host => "" }

To define the host for the links created in mails.
However when using this in config/environments/.rb, it says the method default_url_options doesn't exists.

More to that, there's something odd here as there's already the defaults method, which allows us to define default params.
Why should this method be different from the default params ?

Shouldn't it be better to define the url with

config.action_mailer.default :url_options => { :host => "" }

Instead of having two different but similar methods (one of them which doesn't exists for now).

    I cannot reproduce this failure on rails master. I just added:

    config.action_mailer.default_url_options = { :host => "" }

    To "config/environments/development.rb" and it worked as expected. Could you provide more information to reproduce the bug?

    And the reason we have both :default and :default_url_options it's because they are difference concerns. :default is about your e-mail headers (like :from, :bcc and so on). default_url_options comes from ActionController::UrlFor.

    i've run into this too and don't know what the updated API is supposed to be.

    after adding ActionMailer::Base.default_url_options[:host] = "" to application.rb -

    this is what has to say -

    When using named routes you only need to supply the :host:

    <%= users_url(:host => "") %>

    You will want to avoid using the name_of_route_path form of named routes because it doesn‘t make sense to generate relative URLs in email messages.

    It is also possible to set a default host that will be used in all mailers by setting the :host option in the ActionMailer::Base.default_url_options hash as follows:

    ActionMailer::Base.default_url_options[:host] = ""

    This can also be set as a configuration option in config/environment.rb:

    config.action_mailer.default_url_options = { :host => "" }

    (also note the documentation still references config/environment.rb, and should be updated to config/application.rb)

    This is a problem in the prerelease, but not in master. Perhaps related to #3857?
