Primary Key in XSD DataSource

[hanno]

Hello,
is there a way to define the primary key of a field in the XSD file?

Like in the following XSD snippet:

<xsd:key name="MemberKey">
    <xsd:selector xpath="Member" />
    <xsd:field xpath="@Nick" />
</xsd:key>

But without calling

dataSource.getField("Nick").setPrimaryKey(true);

the field will not be a primary key.


Regards,
Hanno

Hello Hanno,

You can use schema chaining (see DataSource.setInheritsFrom) to mark a field as a primaryKey and add any other presentation-specific metadata (such as user visible titles) required in your UI.

The idea of auto-deriving the primary key based on XML Schema <key> declaration is interesting - we'll look at adding that.

Anything new in this subject? Is it possible now to define primary key directly in XSD schema?
