Custom Identifier - how does it work?

[manfred.schreck]

Hello,

I am using Metabase for a while, and I am happy with it.
Now I am in a situation, that I have to use a custom identifier. The
scenario is that I use Metabase to synchronize data between existing
db/php app and a newly created web application. The existing app
cannot be changed, and a table containing user information has a
login filed as the primary key. An id field cannot be added.

Now my question: How can I get Metabase to work with a field login
insted of id?

Here is my config for that class, that still uses id as the primary
key:
<class>
  <id>login</id>
  <name>z_user</name>
  <variable>
    <name>login</name>
    <length>10</length>
    <type>text</type>
  </variable>
  <variable>
    <name>passwort</name>
    <type>text</type>
    <length>255</length>
  </variable>
  <variable>
    <name>email</name>
    <type>text</type>
    <length>50</length>
    <optional>1</optional>
  </variable>
</class>

I am a bit confused with your references to Metabase.

Do you mean you have an application using Metabase and you want to
integrate with something that uses classes generated by Metastorage?

Currently Metastorage does not support defining custom object identifier
(OID) variables. For now, an implicit OID is assigned to automatic
variable id .

However it is already in my todo list to add support custom OID. Not
only you will be specify another variable as OID, but you also be
allowed to specify more than one OID variable to achieve composite
primary keys. Please be patient.
