===============================================================================
Depending on your application's configuration some manual setup may be required:
1. Ensure you have defined default url options in your environments files. Here
is an example of default_url_options appropriate for a development environment
in config/environments/development.rb:
config.action_mailer.default_url_options = { host: 'localhost', port: 3000 }
In production, :host should be set to the actual host of your application.
* Required for all applications. *
2. Ensure you have defined root_url to *something* in your config/routes.rb.
For example:
root to: "home#index"
* Not required for API-only Applications *
3. Ensure you have flash messages in app/views/layouts/application.html.erb.
For example:
<p class="notice"><%= notice %></p>
<p class="alert"><%= alert %></p>
* Not required for API-only Applications *
4. You can copy Devise views (for customization) to your app by running:
rails g devise:views
* Not required *

Rails cannot recover the underscored form from its camelcase form 'MODEL'.
Please use an underscored name instead, either 'model' or 'mode_l'.
Or setup custom inflection rules for this noun before running the generator in config/initializers/inflections.rb.
