Create email templates that an admin can edit and then send.
Rails 3.2.x through Rails 6
This is the 1.0 series of effective_email_templates.
This requires Twitter Bootstrap 4.
Please check out Effective Email Templates 0.x for more information using this gem with Bootstrap 3.
Add to your Gemfile:
gem 'haml-rails' # or try using gem 'hamlit-rails'
gem 'effective_email_templates'
Run the bundle command to install it:
bundle install
Then run the generator:
rails generate effective_email_templates:install
The generator will install an initializer which describes all configuration options and creates a database migration.
If you want to tweak the table name (to use something other than the default 'email_templates'), manually adjust both the configuration file and the migration now.
Then migrate the database:
rake db:migrate
And import the provided welcome email template:
rake effective_email_templates:import
To manage the content of the email templates, navigate to /admin/email_templates
or add,
link_to 'Email Templates', effective_email_templates.admin_email_templates_path
to your menu.
The installer already created an app/mailers/email_templates_mailer.rb
. You can change this name. And additional mailers can be created, just make sure they extend from Effective::EmailTemplatesMailer
.
To create an email template:
- Create a method inside the mailer, like
def welcome
. The@assigns
instance variable should contain all the variables that are passed to the liquid view. Any variables that end in_url
likeroot_url
will be automatically expanded.
# app/mailers/email_templates_mailer.rb
class EmailTemplatesMailer < Effective::EmailTemplatesMailer
def welcome(user)
@assigns = {
user: {
first_name: user.first_name,
last_name: user.last_name
}
adjective: 'awesome'
}
mail(to: user.email)
end
end
- Create a .liquid file in
app/views/email_templates_mailer/welcome.liquid
.
---
subject: 'Welcome {{ user.first_name }}' # REQUIRED
from: '[email protected]' # REQUIRED
cc: '[email protected]' # optional
bcc: '[email protected]' # optional
---
Welcome {{ user.first_name }} {{ user.last_name }}!
I am a liquid template that is imported to the database, and is then editable.
Thanks for using our site at {{ root_url }}.
- Run
rake effective_email_templates:import
orrake effective_email_templates:overwrite
-
Remember to do this in your staging and production environments as well!
-
The import task can be run even when no new templates have been added and will not overwrite existing database templates. This allows you to run the rake task in a deploy script if you are adding new templates frequently.
- Send the emails like normal:
EmailTemplatesMailer.welcome(user).deliver
All authorization checks are handled via the effective_resources gem found in the config/initializers/effective_resources.rb
file.
To allow a user to see the admin area, using CanCan:
