Question

I am new to Ruby on Rails . This might be a very foolish question.

I have created a migration using

rails generate migration Kapol name:string position:integer

rake db:migrate

Then using phpmyadmin i copied the database already present
I then opened up rails console

My question is can i use the method Kapol.find(1)??
because when i tried it using singular or plural it says

unitialized constant:Kapol

I know that there has to be a method but where to specify it?

Answer 1

You must generate a model in case to create a table for it, because the migration is usually used to modify existing tables.

It might be confusing that the model generator also creates migration file in your migrations folder. The only difference is that the model generator also generates initial code to create table, on the other hand, the migration generator creates only migration file without initial code.

rails generate model Kapol name:string position:integer
