Extend Gem with additional Template and Recipient Functionality (round 2) #28

This will add filters to the smtpapi gem: https://github.com/sendgrid/smtpapi-ruby The template_id will be passed in like other attributes to mail Example: ``` mail = SendGrid::Mail.new do |m| m.to = '[email protected]' m.from = '[email protected]' m.subject = 'Hello world!' m.text = 'I heard you like pineapple.' m.template_id = 1234 end ```

To help encapsulate the substitution logic for templates and how they correlate with email recipients, this model has been introduced. The benefit is now something like this is possible: ```ruby template = Template.new(TEMPLATE_ID) users = User.find(['[email protected]', '[email protected]']) users.each do |user| recipient = Recipient.new(user) recipient.add_substitution(:name, user.name) recipient.add_substitution(:location, user.location) template.add_recipient(recipient) end ``` The next step will be to integrate the `Recipient` and `Template` with `Mail`.

This will add an accessor for the template without an initialization through a template_id

This is the final piece of abstracting recipients, templates and the sending of mail. The use of this would look like: ```ruby users = User.where(email: ['[email protected]', '[email protected]']) recipients = [] users.each do |user| recipient = SendGrid::Recipient.new(user.email) recipient.add_substitution('first_name', user.first_name) recipient.add_substitution('city', user.city) recipients << recipient end template = SendGrid::Template.new('MY_TEMPLATE_ID') client = SendGrid::Client.new(api_user: my_user, api_key: my_key) mail_defaults = { from: '[email protected]', html: '<h1>I like email</h1>', text: 'I like email' subject: 'Email is great', } mailer = TemplateMailer.new(client, template, recipients) mailer.mail(mail_defaults) ```
