Welcome To Mr.Techmaker’s — Fast Flutter Maker Course :)

I teach flutter, dart programming along with design thinking, entrepreneurship in the course.
We will be using the “Learn By Doing” method.
You will need to type in code as you study each lesson.

The goal is to make you ready…

First download the latest database of your app on your local machine with below two commands:

heroku pg:backups:capture

heroku pg:backups:download

you will get the latest database downloaded in a filename latest.dump.<some number>

Now connect to postgresql on your local machine:

sudo -u postgres psql

create a new database fith command :

create database <database_name>;

now logout from postgresql prompt by pressing ctrl+D

Now just import the downloaded prod db into the new created local database :

pg_restore <hyphen><hyphen>no-owner -U karan -d <local_database_name> -1 <downloaded_dump_database_production>;

you are done!

to use the new database in your local rails app just edit the config/database.yml file on your local machine.

development:
<<: *default
database: cmsproddec

just change the database name above and your local rails app with start using the new database.

Enjoy.

Feel free to HMU.

Cheers.

driver = new RemoteWebDriver(new URL(“http://localhost:4444/wd/hub") , option);
