next_migration_number

[andrenth]

Running "rails g wysihat" in rails 3 after installation gives me a NotImplementedError exception in the next_migration_number method. This method is defined under Rails::Generators::Migration::ClassMethods in the rails source, so changing it to be a class method in wysihat fixed it for me:

-def next_migration_number(dirname) #:nodoc:
+def self.next_migration_number(dirname) #:nodoc:

That also worked for me! Thanks!

That fixed the generator for me as well! Thanks!

I'm getting a similar error:

/Users/Alan/.rvm/gems/ruby-1.8.7-p302/gems/railties-3.0.1/lib/rails/generators/migration.rb:50:in migration_template': undefined methodnext_migration_number' for WysihatGenerator:Class (NoMethodError)
from /Users/Alan/.rvm/gems/ruby-1.8.7-p302/gems/wysihat-engine-0.1.13/lib/generators/wysihat_generator.rb:60:in `install_wysihat'

I've tried editing .rvm/gems/ruby-1.8.7-p302/gems/railties-3.0.1/lib/rails/generators/migration with the fix (changes happen on line #29) and it doesn't seem to make a difference.

Can I change the wysihat_generator.rb to fix it? I'm sure I'm doing something terribly wrong.

It seems, that commenting "raise NotImplementedError" in next_migration_number method solves issue.

Having it commented, all worked!

Although the error was coming from ruby-1.8.7-p302, I ended doing what stanislaw suggested in the /ruby-1.8.7-p302@rails3 directory. It must be a RVM thing. That seemed to 'work'. (thanks Stanislaw)

The issue now is that it created the migration file without a timestamp and rake seems to miss it. I just copied/pasted into a new migration - but wondering if there's a way to fix this problem and the generate issue for rails 3?
