hosting

As you know there is a free plan in heroku.com and you can use only 10,000 rows in the database but sometimes your database exceeds those limits and you don't want to pay because the app installation in only for testing purposes. That is why you can use the following commands if you want to to search and find the tables that have the maximum number of records and be able to delete the ones that are not necessary for you

If you are hosting your application on heroku.com and you want to run a task from time to time you can use the add-on scheduler which is free!! but how you can use it?, is it pretty straightforward just do the following: from console inside your project folder application you have to run: [ruby] heroku addons:add scheduler [/ruby]
