NHibernate Many-to-Many Mapping not working
- by ClutchDude
I have a Nhibernate mapping file for a simple user/role mapping.
Here are the mapping files:
Users.hbm.xml
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="Sample.Persistence" namespace="Sample.Persistence.Model">
<class name="User" table="Users">
<id name="UserKey">
<generator class="identity"/>
</id>
<property name="UserName" column="UserName" type="String" />
<property name="Password" column="Password" type="Byte[]" />
<property name="FirstName" column="FirstName" type="String" />
<property name="LastName" column="LastName" type="String" />
<property name="Email" column="Email" type="String" />
<property name="Active" column="Active" type="Boolean" />
<property name="Locked" column="Locked" type="Boolean" />
<property name="LoginFailures" column="LoginFailures" type="int" />
<property name="LockoutDate" column="LockoutDate" type="DateTime" generated="insert" />
<property name="Expired" column="Expired" type="Boolean" generated="insert"/>
<set name="Roles" table="UsersRolesBridge" lazy="false">
<key column="UserKey" />
<many-to-many class="Role"
not-found="exception"
column="RoleKey" />
</set>
</class>
</hibernate-mapping>
Role.hbm.xml
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="Sample.Persistence" namespace="Sample.Persistence.Model">
<class name="Role" table="Roles">
<id name="RoleKey">
<generator class="identity"/>
</id>
<property name="Name" column="Name" type="String" />
<set name="Users" inverse="true" atable="UsersRolesBridge" lazy="false" >
<key column="RoleKey" />
<many-to-many class="User" column="UserKey" />
</set>
</class>
</hibernate-mapping>
I am able to retrieve roles for each user via NHibernate but when I go to save a new object, the roles are not saved in the Bridge table.
The user is created and insert with no issues. I've checked that the Role collection, a field on the user, is being populated with the proper rolekey before the Session.Save() is called.
There is no exception thrown as well.
