  After designing your models you can run and test your project. We generate
  complete list of restful APIs based on your models properties automatically
  without any code.

# Restful API

Once you have defined a model, then you can use create, read, update, and delete (CRUD) operations to add data to the model, manipulate the data, and query it. All Haska models that are connected to persistent data stores (such as a database) automatically have the create, retrieve, update, and delete operations of the PersistedModel class.

For each model we generate a lot of endpoints that you can make query for them and test your API's endpoints in our playground. Before start your restful API service you have to run project first.

Let's explore playground and learn how to works with that ;)
