Re: [DataMapper] can't update json property

[Roman Dzvinkovsky]

Charles,

I've faced similar problem recently. AFAIR the reason is that DataMapper
does not recognize the change of hash under Json property. After several
attempts I came up with workaround:

o.data[:key1][:key2] += 1
# o.save # doesn't work
data = o.data
o.data = nil
o.save
o.data = data
o.save
