I will be sharing all the lessons i create on doingiteasychannel here. All questions needs to be asked in this thread. That are related to this lesson.
I will do my very best to answer all questions.
One question asked in this lesson was why we need to use migrations - easy
Here is why
Migrations are a version control for your database. ( for example the system is broken why -> some column in the db has changed how would you know if not for migrations ? )
A developer can easily get started clone the project and run the migrations.
It makes it easier to deploy there are a lot more if you think about it.
