Django rest frame - get two models

I have multiple models that are associated by Foreign Keys. I can export them all separately using django rest framework on a one to one basis, and I can also export multiple ones nested. However I want to be able to essentially "concatenate" them together into a single json/xml export.

The models in the example below are joined by a one to one foreign key on jobdtl_id. I have some where it's one to many but I'm hoping I can figure that out when I know how to get a view that will link 2 separate models like I want below -

Here's an example of what I want the json to look like by hitting a single URL like

http://localhost/job/4/

{
  "job": {
    "-id": "9878",
    "-name": "This is the job",
    "-master": "blahserver",
    "-dbversion": "234",
    "-xmlversion": "1",
    "jobmst": {
      "jobmst_id": "9878",
      "jobmst_type": "2",
      "jobmst_prntid": "234",
      "jobmst_active": "Y",
      "jobmst_name": "This is the job",
      "jobmst_owner": "Owner",
      "jobdtl_id": "9878",
      "jobmst_lstchgtm": {
        "-date": "Y",
        "#text": "2013-10-23 09:22:08.0"
      },
      "jobmst_prntname": "Parent",
      "jobmst_alias": "9878"
    },
    "jobdtl": {
      "jobdtl_id": "9878",
      "jobdtl_cmd": "blah.exe",
      "jobdtl_failalarm": "NULL",
      "nodmst_id": "NULL",
      "nodlstmst_id": "NULL",
      "jobdtl_inhevent": "Y",
      "jobdtl_inhoptions": "Y",
      "jobdtl_inhagent": "Y",
      "jobdtl_inhrepeat": "Y",
      "jobdtl_inhtime": "Y",
      "jobdtl_timewin": "NULL",
      "jobdtl_saveoutput": "Y",
      "jobdtl_outputname": "NULL",
      "jobdtl_trackmethod": "1",
      "jobdtl_trackcmd": "NULL",
      "jobdtl_deplogic": "1",
      "jobdtl_rerun": "NULL",
      "jobdtl_params": "--blah --ok"
    },
    "jobdep": [
      {
        "jobdep_id": "79670",
        "jobmst_id": "9878",
        "jobdep_type": "1",
        "jobdep_jobmst": "another job",
        "varmst_id": "NULL"
      },
      {
        "-num": "2",
        "jobdep_id": "83783",
        "jobmst_id": "9878",
        "jobdep_type": "1",
        "jobdep_jobmst": "and another",
        "varmst_id": "NULL"
      }
    ],
    "trgjob": [
      {
        "trgjob_id": "22286",
        "trgmst_id": "23455",
        "jobmst_id": "9878"
      },
      {
        "-num": "2",
        "trgjob_id": "28980",
        "trgmst_id": "23521",
        "jobmst_id": "9878"
      },
      {
        "-num": "3",
        "trgjob_id": "28981",
        "trgmst_id": "9237",
        "jobmst_id": "9878"
      }
    ]
  }
}

The models are basically like this -

class Jobdtl(models.Model):
    jobdtl_id = models.IntegerField(primary_key=True)
    jobdtl_cmd = models.TextField(blank=True)
    ....
    jobdtl_duration = models.IntegerField(blank=True, null=True)
    class Meta:
        managed = False
        db_table = 'jobdtl'

class Jobmst(models.Model):
    jobmst_id = models.IntegerField(primary_key=True)
    jobmst_type = models.SmallIntegerField()
    ....
    jobdtl_id = models.ForeignKey('Jobdtl', db_column='jobdtl_id', related_name='mstdtl', blank=True, null=True)
    def __unicode__(self):
        return self.jobmst_name
    class Meta:
        managed = False
        db_table = 'jobmst'

end caveat I'm converting the json from how the XML looks for the existing legacy app which is like so -

<?xml version="1.0"?>
<job id="9878" name="This is the job" master="blahserver" dbversion="532" xmlversion="1">

class MSTSerializer(serializers.HyperlinkedModelSerializer):
    jobdtl_id = DTLSerializer()
    class Meta:
        model = Jobmst
        fields = ('id', 'url', 'jobdtl_id'...)

class DTLSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = Jobdtl
        fields = ('id', 'url',  ...)

Would result in a more correct data structure of

{
    "jobmst_id": 4,
    "jobmst_type": 1,
    "jobdtl_id": {
       "jobdtl_id": 4,
       "jobdtl_cmd": null,
       "jobdtl_duration": 1379
    },

}
