Re: [chicagoboss] Storing MongoDB with Objects
works like magic
%clients.erl
-module(clients, [Id, Listname, Email, Datablock]).
-compile(export_all).
(rahm@can2nac-laptop)14>
(clients:new(id,"Bill","t...@test.com",[{'1',<<"Field1">>},{two,"two"},{three,3}])):save().
{ok,{clients,"clients-53f75484b3769c0ec20b","Bill",
"t...@test.com",
[{'1',<<"Field1">>},{two,"two"},{three,3}]}}
(rahm@can2nac-laptop)15> boss_db:find("clients-53f75484b3769c0ec20b").
{clients,"clients-53f75484b3769c0ec20b",<<"Bill">>,
<<"t...@test.com">>,
[{'1',<<"Field1">>},{two,"two"},{three,3}]}

Re: [chicagoboss] Storing MongoDB with Objects
Jason,
This may not be your problem, but . . . bear in mind that boss_db does not
support the storage of arbitrary erlang terms in a boss db field - check
the documentation here http://www.chicagoboss.org/api-record.html to see
what is supported. (It may be that your bson falls under the category of
'binary' in which case you should not have an issue), Now, although that is
the OFFICIAL (i.e. documented) position, CB does not do anything to prevent
it, so it depends on the adaptor for the particular db you are using. The
Mnesia adaptor does, but that is because Mnesia runs in erlang. It is quite
possible that the Mongo adaptor does not support this behaviour.
I should point out that my experience is all with Mnesia. Perhaps someone
who knows Mongo better than I can help you with your real problem. LoL

Re: [chicagoboss] Storing MongoDB with Objects
Hi Kia,
I changed the save
ClientList:save().
Now I get an error that looks like this
[error] gen_server <0.285.0> terminated with reason: no function clause
matching bson_binary:put_field_accum("Field1", "Name", <<>>) line 93
