I'm building an email system that stores my different emails in the database and calls the appropriate "deliver_" method via method_missing (since I can't explicitly declare methods since they're user-generated).
My problem is that my rails app still tries to render the template for whatever the generated email is, though those templates don't exist. I want to force all emails to use the same template (views/test_email.html.haml), which will be setup to draw their formatting from my database records.
How can I accomplish this? I tried adding render :template => 'test_email' in the test_email method in emailer_controller with no luck.
models/emailer.rb:
class Emailer < ActionMailer::Base
def method_missing(method, *args)
# not been implemented yet
logger.info "method missing was called!!"
end
end
controller/emailer_controller.rb:
class EmailerController < ApplicationController
def test_email
@email = Email.find(params[:id])
Emailer.send("deliver_#{@email.name}")
end
end
views/emails/index.html.haml:
%h1 Listing emails
%table{ :cellspacing => 0 }
%tr
%th Name
%th Subject
- @emails.each do |email|
%tr
%td=h email.name
%td=h email.subject
%td= link_to 'Show', email
%td= link_to 'Edit', edit_email_path(email)
%td= link_to 'Send Test Message', :controller => 'emailer', :action => 'test_email', :params => { :id => email.id }
%td= link_to 'Destroy', email, :confirm => 'Are you sure?', :method => :delete
%p= link_to 'New email', new_email_path
Error I'm getting with the above:
Template is missing
Missing template
emailer/name_of_email_in_database.erb in view
path app/views
