Accessing User Roles Using Oracle WebCenter Ensemble Adaptive
Tags
The role* tags in the Oracle WebCenter Ensemble tag library
allow pagelets to modify content based on the role of the current
user.
The
pt:ensemble.roleexpr tag
evaluates a role expression and stores the result as a boolean in
memory. This tag is designed to work with the
pt:logic.if tag as shown below.
<pt:ensemble.roleexpr pt:expr="hasRole Default Role from Seed State" pt:key="boolvalue"/>
<pt:logic.if pt:expr="$boolvalue">
<pt:logic.iftrue>
<!-- This is displayed if expr evaluates to true. -->
</pt:logic.iftrue>
<pt:logic.iffalse>
<!-- This is displayed if expr evaluates to false. -->
</pt:logic.iffalse>
</pt:logic.if>
The
pt:ensemble.rolelist tag stores a list of the roles for the current user in memory. The
data is stored as a collection, and each item in the collection is
a variable containing the role name. This can be used with the
logic.foreach tag to iterate over role data as shown below.
<pt:ensemble.rolelist pt:key="roles"/>
<pt:logic.foreach pt:data="roles" pt:var="role">
<pt:logic.value pt:value="$role"/>
<pt:logic.separator></pt:logic.separator>
</pt:logic.foreach>
