ActsAsMonitor

Provide a way to monitor the status of a model. The health of the model is checked by private/public methods, defined by user

Installation

Add this line to your application's Gemfile:

gem 'acts_as_monitor'

And then execute:

$ bundle

Or install it yourself as:

$ gem install acts_as_monitor

Copy icons and other files

rails g acts_as_monitor:install

Usage

#app/models/user.rb
class User < ActiveRecord::Base
  acts_as_monitor

  ... your code ...

  private

  def warn_stange?
    ... do some checks and return true or false
    true
  end

  def warn_not_now?
    ... do some checks and return true or false
    false
  end

  def error_terrible?
    ... do some checks and return true or false
    true
  end
end

You can now check the status of your model using the following code: @user = User.new

@user.status
> {:warn => [:warn_strange?], :error => [:error_terrible?]}

@user.status_flag
> :red

You can query the status of your model with:

User.status_flag_equals(:red)   #=> Array of users with :red status

User.status_flag_not_equals(:red) #=> Array of users with status not equlas to :red

You can use the monitor_tag helper to view a red/green/yellow rapresentation:

#app/views/users/index.html.erb
<%= monitor_tag_js %>     #Creates hidden div and load css and javascript
...
<%= monitor_tag(@user) %>

Clicking the icon you'll receive, via Ajax, the full error/warning list

Internationalization

You can localize the output modifing the acts_as_monitor.it.yml, or cloning for the language you prefear. Name of models is retrived via human_name, so you have to localize the ActiveRecord to change names: it: activerecord: models: your_model_name: Your Model Name

      namespace:
        namespaced_model_name: Your Namespaced Model Name

Personalization

Feel free to modify the fololwing files to change layouts and text :

• public/stylesheets/acts_as_monitor.css
• config/locales/act_as_monitor.it.yml

If you need a deeper personalization you can try to overload app/views/acts_as_monitor/monitors/show.html.erb conaining the page template for the error/warning list
