ruby on rails: How to create table for a new model

Question

I use

rails generate model mynewmodel string:name string:description

to generate a new model. How do I deploy this new model to my develop databse ? I already have a bunch of databases in my sqlite db.

I have tried

rake db:migrate

it seemed having trouble to generate this new table in db.

update: added error message

==  CreateMynewmodels: migrating ===============================================
-- create_table(:mynewmodels)
rake aborted!
An error has occurred, this and all later migrations canceled:

undefined method `name' for #<ActiveRecord::ConnectionAdapters::TableDefinition:0x3ad5c50>

Tasks: TOP => db:migrate

Thanks

What you're doing is correct (rake db:migrate). We can't help without seeing error messages. — user229044

The order of your fieldname:type combo is incorrect. Try

rails generate model mynewmodel name:string description:string

The error in rails generate model mynewmodel string:name string:description

You should swap string and name

rails generate model mynewmodel name:string description:string

Use name:string instead of string:name same for description

Great article for advanced usage: Advanced Rails model generators

Pay attention that you have to wrap parameter price:decimal{10,2} to quotes. It's vital and you may have incorrect behavior of generator if you don't do it.
