Hi
I downloaded 0.9.10 and merb-gen'ed a simple test app. I commented out
DM related stuff in config files and added "dependency 'activerecord',
'2.1.2' " to dependencies.rb. Also, replaced all DM references in
init.rb with AR lines.
Not that anything is wrong with DM but I need to port an existing
application from Rails to merb and don't want to bite more than
possible to chew. So, first rails to merb then AR to DM.
One of the controllers returns json :
def index
data_model = {
:success => true,
:data => [
{
:name => 'j1'
}
]
}
render_js data_model.to_json, :layout => false, :template => false
end
However, to_json method dies with this stacktrace. Seems like
something to do with AR since same code works great with DM. Has
anyone seen this issue with to_json and AR? Any ideas on how to work
around it. thanks.
