Ok, going through the book Ruby on Rails Made Easy, and I made a
mistake here. I forgot to add in two columns into my table. so i tried
to add them back into the migration file and run it again, but after
checking with the #ROR channel on IRC i was informed that this is not
possible. I needed to make a new migration file.
I have done this, but I am obviously doing something wrong. If someone
could point out my error it would be appreciated.
Original migration file.
class CreateCategories < ActiveRecord::Migration
def self.up
create_table :categories do |t|
t.column :name, :string
end
Category.create :name => "Furniture"
Category.create :name => "Miscellaneous"
add_column :classifieds, :category_id, :integer
Classified.find(:all).each do |c|
c.update_attribute(:category_id, 4)
end
end
def self.down
drop_table :categories
remove_column :classifieds, :category_id
end
end
Migration file I tried to create.
class AddColumns < ActiveRecord::Migration
def self.up
create_t.column :name, :string
end
Category.create :name => "Electronics"
Category.create :name => "Real Estate"
end
def self.down
drop_table :categories
remove_column :classifieds, :category_id
end
end
receive an unexpected kEND expecting $ error when trying to run rake
db:migrate on the new file.
Thank you,
Dave
