Hi, there. I got an error when I ran the migration to add a filed to
database. In the migration file,
def self.up
change_table :contents do |t|
t.add_string :new_names
end
end
def self.down
change_table :contents do |t|
t.remove_column :new_names
end
end
The error is:
== AddMoreFieldsToContents: migrating
========================================
-- change_table(:contents)
rake aborted!
An error has occurred, this and all later migrations canceled:
undefined method `add_string' for
#<ActiveRecord::ConnectionAdapters::Table:0x2b
b9b74>
If I used add_column method, everything ran fine. I am running Rails
2.3.4. Any thoughts on the undefined method error?
Thanks in advance.
