mapping mismatch, is there any way to fix this ? about modelmapper HOT 4 CLOSED

I checked to see what mappings are created with each of the 3 matching strategies using ModelMaper 0.5.4:

for (Object o : modelMapper.getTypeMap(a.Down.class, b.Down.class).getMappings())
  System.out.println(o);

And here's what we have:

STRICT:

PropertyMapping[Down.updateDate -> Down.updateDate]

STANDARD:

PropertyMapping[Down.pk.upId -> Down.pk.up.id]
PropertyMapping[Down.updateDate -> Down.updateDate]

LOOSE:

PropertyMapping[Down.pk.upId -> Down.pk.up.id]
PropertyMapping[Down.up.updateDate -> Down.pk.up.updateDate]
PropertyMapping[Down.updateDate -> Down.updateDate]

What mappings are you expecting?

from modelmapper.

Since I used MatchingStrategies.STRICT to map other child model, there is no way to change MatchingStrategies now.
And even I changed to LOOOSE,

for (Object o : modelMapper.getTypeMap(a.Down.class, b.Down.class).getMappings())
System.out.println(o);

prints right mapping, but the value was not assigned correctly. (updateDate)

Is there any way to set the mapping manually like this

PropertyMapping[Down.up.updateDate -> Down.pk.up.updateDate]
PropertyMapping[Down.updateDate -> Down.updateDate]

(under MatchingStrategies.STRICT)

I tried using() or configure , but none of them works.

from modelmapper.

It looks like the value for Down.updateDate is correctly assigned. I'm seeing the same result as you posted above:

Down [pk=null, updateDate=Fri Apr 03 00:00:00 PDT 3333]

MatchingStrategies are used when mappings are first created for a pair of types, which is when the TypeMap for a pair of types is first created. Once created, changing the MatchingStrategy has no effect. One solution is to create a different ModelMapper instance which will allow you to use a different matching strategy for a pair of types.

You can manually add additional mappings to a TypeMap using the mapping API:

http://modelmapper.org/user-manual/property-mapping/

Something like:

modelMapper.addMappings(new PropertyMap<a.Down, b.Down>() {
  protected void configure() {
    map().getPk().getUp().setId(source.getPk().getUpId());
  }
});

from modelmapper.

Closing for now.
