Re: [castor-user] [XML] Correct reference mapping for collection

[Daniel Wachter]

Hi werner

I read the the reference how-to, but I don't get it to work as I would.
The keys appears in on the model, but where are the key definitions?

I read the reference many times, but not getting it working...
Can you give me some hints what are my problems?
Thank you
Daniel



I made a mapping like this:
---------------------------------------------
<?xml version="1.0"?>
<!DOCTYPE mapping PUBLIC "-//EXOLAB/Castor Mapping DTD Version 1.0//EN"
"http://castor.org/mapping.dtd";>

<mapping>

        <class name="com.solarmax.maxsim.model.Datakey" identity="id">
                <map-to xml="data-key" />
                        <field name="id" type="string">
                                <bind-xml name="id" node="attribute" />
                        </field>

                        <field name="description" type="string">
                                <bind-xml name="description" node="attribute" />
                        </field>
        </class>

        <class name="com.solarmax.maxsim.model.DeviceModel">
                <map-to xml="model" />
                        <field name="name" type="string">
                                <bind-xml name="name" node="element" />
                        </field>

                        <field name="attributes" 
type="com.solarmax.maxsim.model.Datakey"
collection="collection">
                                <bind-xml name="data-key" reference="true" />
                        </field>
        </class>

</mapping>


And get a xml file like this:
---------------------------------------------
<models>
    <model xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:type="model">
        <name>S 2000C</name>
        <data-key>rad</data-key>
        <data-key>rad_e_day</data-key>
        <data-key>rad_e_month</data-key>
        <data-key>rad_e_tot</data-key>
        <data-key>rad_e_year</data-key>
        <data-key>status_alarm</data-key>
        <data-key>status_system_new</data-key>
    </model>
    <model xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:type="model">
        <name>S 4000C</name>
    </model>
    <model xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:type="model">
        <name>S 5000C</name>
    </model>
</models>
