Hi,
I want to check how a table column that supports a relationship should be
defined.
I have the following in my transfer XML file.
<package name="Price">
<object name="Price" table="Price">
<id name="priceId" column="priceId" type="numeric"/>
<property name="packageId" column="packageId" type="numeric"
nullable="false" />
<property name="featureId" column="featureId" type="numeric"
nullable="true" />
<property name="periodCovered" column="periodCovered"
type="string" nullable="false" />
<property name="billingRate" column="billingRate"
type="string" nullable="false" />
<property name="startDate" column="startDate" type="date"
nullable="true" />
<property name="endDate" column="endDate" type="date"
nullable="true" />
<property name="price" column="price" type="numeric"
nullable="false" />
<property name="isSpecialOffer" column="isSpecialOffer"
type="boolean" nullable="false" />
<property name="isActive" column="isActive" type="boolean"
nullable="false" />
</object>
</package>
In fact packageId and FeatureId are both foreign key fields so I propose to
add two many to one entries:
<package name="Price">
<object name="Price" table="Price">
<id name="priceId" column="priceId" type="numeric"/>
<property name="packageId" column="packageId" type="numeric"
nullable="false" />
<property name="featureId" column="featureId" type="numeric"
nullable="true" />
<property name="periodCovered" column="periodCovered"
type="string" nullable="false" />
<property name="billingRate" column="billingRate"
type="string" nullable="false" />
<property name="startDate" column="startDate" type="date"
nullable="true" />
<property name="endDate" column="endDate" type="date"
nullable="true" />
<property name="price" column="price" type="numeric"
nullable="false" />
<property name="isSpecialOffer" column="isSpecialOffer"
type="boolean" nullable="false" />
<property name="isActive" column="isActive" type="boolean"
nullable="false" />
<manytoone name="Feature">
<link to="Feature.Feature" column="featureId" />
</manytoone>
<manytoone name="Package">
<link to="Package.Package" column="packageId" />
</manytoone>
</object>
</package>
Should the property tags be removed at the same time? If so how do I specify
that the featureId is optional since there seems not to be an equivalent to
nullable="true"?
Yes you need to remove the property for your foreign key.
You don't need to specify that the column is nullable. You simply don't add
a child object for feature and/or package.
When you pull the saved record from cache/database you will need to check to
make sure that your price object hasFeature or hasPackage before you do a
getFeature or getPackage, otherwise it will throw an error.
