Effective Mailchimp

Subscribe and unsubscribe users to individual mailchimp campaigns.

Update Mailchimp whenever a user changes their demographics

This requires Rails 6+ and Twitter Bootstrap 4 and just works with Devise.

Please first install the effective_datatables gem.

Please download and install the Twitter Bootstrap4

Add to your Gemfile:

gem 'haml'
gem 'effective_mailchimp'

Run the bundle command to install it:

bundle install

Then run the generator:

rails generate effective_mailchimp:install

The generator will install an initializer which describes all configuration options and creates a database migration.

If you want to tweak the table names, manually adjust both the configuration file and the migration now.

Then migrate the database:

rake db:migrate

Please add the following to your User model:

effective_mailchimp_user

and

Add a link to the admin menu:

- if can? :admin, :effective_mailchimp
  - if can? :index, Effective::MailchimpList
    = nav_link_to 'Mailchimp lists', effective_mailchimp.admin_mailchimp_lists_path

To add the fields to your existing users form

= form_with(model: user) do |f|
  = f.text_field :first_name
  = f.text_field :last_name
  = mailchimp_user_fields(f)
  = f.submit

end

if user.admin?
  can :admin, :effective_mailchimp

  can([:index, :edit, :update], Effective::MailchimpList)
  can(:can_subscribe, Effective::MailchimpList) { |list| !list.can_subscribe? }
