Rails 4 - mailer - how to pass arguments to a mailer method - ruby-on-rails

Question

I'm trying to figure out how to setup a mailer class in my Rails 4 app.
I have made a mailer called admin_notes. I want to use it to send emails to the internal team when certain actions are taken across the site.
In my mailer/admin_note.rb, I have:
class AdminNote < ApplicationMailer
def unknown_organisation(organisation_request, user_full_name, name)
#organisation_request =
#user_full_name =
#organisation_request.name =
# #greeting = "Hi"
mail( to: "test#testerongmail.com",from: "test#testerongmail.com", subject: "A new organisation")
end
end
I have an organisation_requests model. It has:
class OrganisationRequest < ActiveRecord::Base
belongs_to :profile
delegate :user_full_name, to: :profile, prefix: false, allow_nil: true
The organisation request table has an attribute called :name in it.
When a new organisation request is created, I want to send an admin note to the internal team, alerting someone to start a process.
I'm struggling to figure out how I define the three variables in the mailer method.
I plan to add the send email call to the create action in the organisation requests controller.
How can I set these variables?
Form to create an organisation request is:
<%= simple_form_for(#organisation_request) do |f| %>
<%= f.error_notification %>
<div class="form-inputs">
<%= f.input :organisation_id, collection: #all_organisations << ['other', nil] %>
</div>
<div class="form-inputs">
<%= f.input :name %>
</div>
<div class="form-actions">
<%= f.button :submit, "Create", :class => 'formsubmit' %>
</div>
<% end %>
NEW ATTEMPT:
I have a create action in my organisation controller, I added this service class request for an email:
def create
#organisation_request = OrganisationRequest.new(organisation_request_params)
#organisation_request.profile_id = current_user.profile.id
if #organisation_request.save
NewOrgRequestService.send_unknown_organisation_requested_flag(organisation_request)
return redirect_to(profile_path(current_user.profile),
flash[:alert] => 'Your request is being processed.')
else
# Failure scenario below
#all_organisations = Organisation.select(:title, :id).map { |org| [org.title, org.id] }
render :new
end
end
I then have a services/organisations requests/NewOrgRequestService.rb
class OrganisationRequest < ActiveRecord::Base
class NewOrgRequestService
attr_accessor :organisation_request
def self.send_unknown_organisation_requested_flag(organisation_request)
if #organisation_request.name.present?
AdminNote.unknown_organisation_requested(organisation_request, user_full_name, name).deliver_later
end
end
end
end
The AdminNote mailer has:
class AdminNote < ApplicationMailer
layout 'transactional_mailer'
def unknown_organisation_requested(organisation_request, user_full_name, name)
#organisation_request = #organisation_request
#user_full_name = #organisation_request.user_full_name
#name = organisation_request.name
# #greeting = "Hi"
mail
to: "test#testerongmail.com",from: "test#testerongmail.com", subject: "A new organisation"
end
end
This doesnt work, but I'm wondering if Im on the right track? Im not sure if the create action in the controller needs to have some kind of reference to the services/organisation_requests/ path that gets to the file??
I think I may have made a bigger mess than I started with - but I'm out of ideas for things to try next.

Answer 1

This may help you.
In your mailer method
def unknown_organisation(org,user)
#org = org
#user = user
mail(to: "test#testerongmail.com",from: "test#testerongmail.com", subject: "A new organisation")
end
In your controller method after saving organization_request and this is how you set your variable. You can pass variable you want.
AdminNote.unknown_organization(#organization_request, current_user).deliver_now
In your mailer template access passed value as you do in action view. And this is how you use your variable.
<%= #org.name %>
<%= #org.full_name %>
Hope this helps
If you want to queue message or send later you can use ActiveJob to send mails in the background.

I know I am super late but here I go.
I understand that you are trying to send in some parameters (values) to mailer so that you can use it while sending an email.
To do so you just need to define a mailer method that accepts some parameters. What you have done is right in your AdminNote Mailer unknown_organization method.
Let's get to your NEW ATTEMPT.
Everything you have done there seems about right except you are passing an undefined variable organization_request. You have created an instance variable #organization_request but you are passing something that is not defined. Here
NewOrgRequestService.send_unknown_organisation_requested_flag(organisation_request)
That is your first problem. This can be improved as:
Your Organizations#create
def create
#organisation_request = OrganisationRequest.new(organisation_request_params)
#organisation_request.profile_id = current_user.profile.id
if #organisation_request.save
#organisation_request.send_unknown_organisation_requested_flag
redirect_to(profile_path(current_user.profile),
flash[:alert] => 'Your request is being processed.')
else
# Failure scenario below
#all_organisations = Organisation.select(:title, :id).map { |org| [org.title, org.id] }
render :new
end
end
And your model can be as follows:
class OrganisationRequest < ActiveRecord::Base
def send_unknown_organisation_requested_flag
if self.name.present?
AdminNote.unknown_organisation_requested(self).deliver_later
end
end
end
I don't know why you are defining a class inside your model class.
Your Mailer should look like below:
class AdminNote < ApplicationMailer
layout 'transactional_mailer'
def unknown_organisation_requested(organisation_request)
#organisation_request = organisation_request
#user_full_name = #organisation_request.user_full_name
#name = organisation_request.name
# #greeting = "Hi"
mail
to: "test#testerongmail.com",from: "test#testerongmail.com", subject: "A new organisation"
end
end
There are a lot of typos and method implementation errors here.
