I'm having a hard time figuring out the "Rails Way" to add a email confirmation URL to a mailer.
I'm opting not to do this purely RESTfully because, well, it's difficult with text email because they can't PUT
requests.
so here's my routes.rb: get 'confirm/:id' => 'Confirmations#confirm'
and in my mailer I'd like to put email_confirm_url(@user.email_token)
where I want the URL to occur.
I created a helper:
#app/helpers/confirmations_helper.rb
module ConfirmationsHelper
def email_confirm_url(token)
"/confirm/#{token}"
end
end
this all works, sort of, except when I call email_confirm_url(@user.email_token)
…
I literally get: " /confirm/abcdefg…
"
When what I want is: http://myhostname/confirm/abcdefg…
Or in development: http://localhost:3000/confirm/abcdefg…
How can I make my URL helper behave more like the built in <resource>_path
and <resource>_url
helpers in Rails? though realistically I suppose I really only need _url
.
#Edit: I have this in my environment config:
#config/environments/development.rb
...
config.action_mailer.default_url_options = { :host => "localhost:3000" }
In order to access the request object you should implement this function in the controller for your mailer and pass it to the template with a variable.
app/mailers/emailer.rb
@tracking_url = "http://#{request.host}:#{request.port}/confirm/#{token}"
app/view/emailer/template_name.html.erb
<%= link_to 'name', @tracking_url %>
What about using an already existing url plus concatenation? Ie you can use root_path
and root_url
, then you concatenate and the behavior is exactly the same as rails!
For example you can do this:
def mystrangemethod_url(option1, option2)
"#{ root_url }/#{ option1 }/#{ option2 }"
end
And you are done. Easy and the only requirement is set set your root path in routes.rb . Also with the option you have set in development.rb, it will work also in mailers too.
I recently wrote a helper to convert my _path
method into a _url
method.
Rails uses ActionDispatch::Http::URL.full_url_for
to produce the _url
methods, and passes in Rails.application.routes.default_url_options
to set the host
, port
, and protocol
.
This means you can generate a URL from a given path with
ActionDispatch::Http::URL.full_url_for(Rails.application.routes.default_url_options.merge(path: path))
My work in progress helper looks like:
def self.url_helper(route_name)
define_method("#{route_name}_url") do |*args|
path = public_send(:"#{route_name}_path", *args)
options = Rails.application.routes.default_url_options.merge(path: path)
ActionDispatch::Http::URL.full_url_for(options)
end
end
This could then be used in combination with your path helper to build an email_confirm_url
method:
url_helper :email_confirm
def email_confirm_path(token)
"/confirm/#{token}"
end
