How to add a column to all connected nodes - mnesia table
I am trying to add new column to an existing mnesia table. For that, I use following code.
test()->
Transformer =
fun(X)-> % when is_record(X, user) -> %previous users
#userssname = X#user.name,
age = X#user.age,
email = X#user.email,
year = 1990
end,
AF = mnesia:transform_table(user, Transformer,record_info(fields, userss),userss),
mnesia:sync_transaction(AF).
Two records I have
-record(user,name,age,email).
-record(users,name,age,email,year).
I want to update all connected node's tables. But it fails.
aborted,badarg,aborted,"Bad transform function",user,
#Fun<test.2.61379004>,'otherserver@192.168.169.1',
badfun,#Fun<test.2.61379004>,
,infinity,mnesia
What is the problem here?

The problem is that an anonymous function can only be called on nodes where the module that defines it is loaded. I guess you loaded the module containing the test function only on one node in the cluster - you need to load it on all nodes for this to work. You can use the nl command ("network load") instead of l in the Erlang shell for that:
nl(my_module).
nl and other commands are described here.

yes, this solved my issue. runningnl(module).in lowest version if there are multiple versions of erlang solved the issue completely.
