Basic Doubts

I’ve just started a project and I’ve been having some basic doubts. Firstly, I created my db schema using a db modeling tool. Then I generated the tables according to that model. After I created the schema.rb. The database.yml is ok and also the first migration. My doubt is: when I run script/generate scaffold Post for example, it creates my view without any field, even if all the tables are created and my migration before scaffolding has the correct definition to the Post table. Instead of using the current migration, the scaffold command creates a new one. Is there any way to run scaffold and do not create a new migration without fields? I wouldn’t like to write down the schema of each table every time I wanted to use scaffold. Second doubt: Can I run script/generate model Post without create a new migration or write down the fields definition? I’d like to use what is on the database and on the current migration (the whole schema) Thanks in advance

You probably want to either:

  1. Move beyond using the scaffold and roll your own code once you understand what’s going on

  2. START with the scaffold as a place to begin and let it create the initial migration, model, controller, etc.

Second doubt: Can I run script/generate model Post without create a new migration or write down the fields definition? I’d like to use what is on the database and on the current migration (the whole schema)

You can run just:

script/generate model

to get help on the generator (or just script/generate to see what generators are available)

You want the --skip-migration option. You can also just create your own model file (and test or spec file to go along with it).
