How do I transfer content of production databse to my development database

Dear experts,

I have a rails application that I was running on production environment. The data upon interacting with application on browser was therefore added to the production database. I would like to know if there is a way I could have this new data to my development database.

All the three databases: development, production, and database are already created. It is just the production and development database have different data in tables. Also, would transfering data from production to development overide the exixiting data in tables of development database.

Thank you
