Access from common class

Hello!

I have made a common class and put it to the /lib folder of my Rails application. Now I have some problems with access to:

1. Mailers Call to SupportMailer.send_activation_email gives an error: NoMethodError (undefined method `send_activation_email' for SupportMailer:Class):

Ok, I have changed my SupportMailer class - give a prefix to the function function send_activation_email -> function self.send_activation_email But in this case the Mailer doesn't see other models and gives an error:    NoMethodError (You have a nil object when you didn't expect it!    You might have expected an instance of ActiveRecord::Base.    The error occurred while evaluating nil.=):        /app/models/support_mailer.rb:14:in `send_activation_email'

How can I access mailers?

2. Functions from application.rb I have added a function (send_sms) to the ApplicationController, but how can I access it from common class in /lib folder? I have tried: send_sms ApplicationController::send_sms But in both cases I have got NoMethodError

How can I access this global function?

I'm lost in all the dependencies and don't know where to place global functions and classes and how to connect from them to another parts of the application....

That's not how mailers work. Typically your mailer method would be
called activation_email (and it must be an instance method - not a
class method) Rails then magically lets you do
SupportMailer.deliver_activation_email /
SupportMailer.create_activation_email

It's not a global function. It's an instance method added to all
controllers

I'm lost in all the dependencies and don't know where to place global functions and classes and how to connect from them to another parts of the application....

in foo.rb class Foo    def self.some_function    end end

call Foo.some_function anywhere you want (you could of course add the
method to a more appropriate model class if there is one)

It's not a global function. It's an instance method added to all controllers

Ok, but I want to render a template in this function. How can I do that if I put it outside the controller (for example, into a separate class in a /lib folder)?

Other answers are really helpful, thank you :slight_smile: Actually I still cannot force my Mailer to work, it reports about "undefined method `activation_email'", although this method exists and is an instance (not class) method....

What are you doing to try and send an email. It should be SupportMailer.deliver_activation_email.
