New subject: [Users] Avpops Module

28 Nov 2005

Elena,

My parameters to avp_db_load, as requested, are:

modparam("avpops","avp_url","mysql://openser:openserrw@localhost/openser")
...
modparam("avpops","db_scheme",

"scheme1:uuid_col=uuid;value_col=phone;value_type=string;table=subscriber")

The columns uuid, and phone are valid columns from the subscriber table.

This causes the following to be logged to syslog on openser startup:
Nov 27 23:53:08 ser1 openser[2085]: Maxfwd module- initializing 
Nov 27 23:53:08 ser1 openser[2085]: AVPops - initializing 
Nov 27 23:53:08 ser1 openser[2085]: ERROR:avpops_init: "AVP_DB" present but
"AVP_TABLE" found empty 
Nov 27 23:53:08 ser1 openser[2085]: init_mod(): Error while initializing module avpops 

I did base it on the example from the avpops tutorial. I don't understand why this
error is generated. I thought the whole point of using db_scheme was that you didn't
have to call modparam on the table name (as well as the uuid, attribute columns etc).

I could really do with a little help!

Thanks.
Douglas.

The avpops module documentation at:
http://www.openser.org/docs/modules/1.0.x/avpops.html#AEN165

has the following example under the db_scheme command:
...
modparam("avpops","db_scheme",
"scheme1:table=subscriber;uuid_column=uuid;value_column=first_name")
...

which causes the following error to be reported in syslog.conf:
Nov 27 14:24:52 ser1 openser: ERROR:avpops:parse_avp_sb_scheme: unknown attribute
<uuid_column>
Nov 27 14:24:52 ser1 openser: ERROR:avpops:avp_add_db_scheme: falied to parse scheme
Nov 27 14:24:52 ser1 openser: parse error (102,3-4): Can't set module parameter

Why?

 	Thanks for reporting this, docs will be updated.

...

The example at the 'alleged' tutorial at:
http://www.voice-system.ro/docs/avpops/

which is just the docs at openser.org cut and pasted mostly has this example:
...
modparam("avpops","db_scheme",
"scheme1:uuid_col=uid;value_col=job;value_type=string;table=emp")
...

which does not generate any errors in syslog.
HOWEVER, when avp_db_load() is called, the following is logged to syslog.conf:

Nov 27 14:21:42 ser1 openser[2424]: ERROR:avpops_init: "AVP_DB" present but
"AVP_TABLE" found empty
Nov 27 14:21:42 ser1 openser[2424]: init_mod(): Error while initializing module avpops

Why??? The docs say I can use dbscheme to use a non standard AVP table, which is what I am
trying to do, namely the subscriber table. If I can use dbscheme to define the columns
from another table, why is OpenSER complaining that I haven't called
modparam("avpops","avp_table","avptable")?????

 	What are the parameters of avp_db_load() in your case? Maybe this
	example (also from avpops tutorial) helps you:

	modparam("avpops","db_scheme",
	        "scheme1:uuid_col=uid;value_col=job;value_type=string;table=emp")

	avp_db_load("$uuid","s:jobs/*$scheme1*");
	- load from table 'emp', using 'uid' column as uuid and 
	  'job' column as string value into AVP name 'jobs'

	Bye,
	Ramona

...
 Doug.
