Hello guys,
In revision 1816 I added the code to dynamically define a class when a
ActiveRecord::Base subclass is defined.
However at the moment the only way I could get this to work is by
using old evil eval, but I would rather define it with
Object.const_set().
If I use Object.const_set() I get the following error:
/Library/Frameworks/RubyCocoa.framework/Versions/A/Resources/ruby/osx/objc/oc_import.rb:323:in
`objc_instance_method_type': no implicit conversion from nil to
integer (TypeError)
from /Library/Frameworks/RubyCocoa.framework/Versions/A/Resources/ruby/osx/objc/oc_import.rb:323:in
`_ns_enable_override?'
from /Library/Frameworks/RubyCocoa.framework/Versions/A/Resources/ruby/osx/objc/oc_import.rb:313:in
`_ns_behavior_method_added'
from /Library/Frameworks/RubyCocoa.framework/Versions/A/Resources/ruby/osx/objc/oc_import.rb:618:in
`method_added'
from tc_active_record.rb:39
The code:
class ActiveRecord::Base
class << self
alias_method :__inherited_before_proxy__, :inherited
def inherited(klass)
proxy_klass = "#{klass.to_s}Proxy"
unless Object.const_defined?(proxy_klass)
# eval "class ::#{proxy_klass} < OSX::ActiveRecordProxy; end;"
# FIXME: This leads to a TypeError originating from:
oc_import.rb:618:in `method_added'
Object.const_set(proxy_klass, Class.new(OSX::ActiveRecordProxy))
end
self.__inherited_before_proxy__(klass)
end
end
end
Could somebody explain to me why this error occurs?
Cheers,
Eloy
