Rails export and import object with relations

I'm new with Ruby and Rails.

Is there any simple way to export from one instance of application one object with 2 related models and import it to another?

Structure is:

- Model1
- - Model1 has many Model2
- - - Model2 has many Model3

Or may be is there any way to export/import MySql records?

You can use like that:

@new_model1 = @model1.includes(:model2 => [:models3]).clone
@new_model.save()

For switching connection between database you can use magic connection

You have to build it yourself. This looks like a data dump (backup services or CSV dumps). You also can dump it as JSON.
