Re: Admin: Add new dataset with a pre-selected foreign key?

Take a look at filters in the admin. You might be able to add log entries to recent items using an appropriate ModelAdmin on 'entry_created'

https://docs.djangoproject.com/en/dev/ref/contrib/admin/#django.contrib.admin.ModelAdmin.list_filter

Then use an InlineModelAdmin

https://docs.djangoproject.com/en/dev/ref/contrib/admin/#django.contrib.admin.InlineModelAdmin

You could then select the sample by finding recently added samples, clicking on it, then add the log entry

Hi,

I have a data model like this:
class Samples(models.Model): 
  sample_id = models.CharField(max_length=128, help_text='Id of the sample')
  entry_created = models.DateTimeField(auto_now_add=True)
  sample_status = models.CharField(choices=SAMPLE_STATUS_CHOICES, max_length=128)
  comments = models.TextField(null=True, blank=True)
  def __unicode__(self):
    return ("%s" % (self.sample_id))

class StatusLog(models.Model):
  sample_id = models.ForeignKey(Samples)
  lsu_proc_id = models.IntegerField()
  orig_lab = models.ForeignKey(OriginatingLab)
  cruise_id = models.ForeignKey(Cruises)
  tier = models.ForeignKey(Tiers)
  orig_tier_tote_nr = models.IntegerField()
  gear_type = models.ForeignKey(GearType)
  orig_number_jars = models.IntegerField()
  all_consumed = models.CharField(max_length=3, choices=YES_NO_CHOICE)
  def __unicode__(self):
    return ("%s %s" %(self.sample_id, self.lsu_proc_id))

....

So first I add a Sample, and later I want to add a status log entry - using the admin interface.
Problem: My list of samples will be LONG (right now roughly 1000 entries, more are coming).

Is there any way that I can call the "add" page (http://MYSERVER/admin/statuslog/statuslog/add/) with the sample already preselected, so I don't have to go through the whole list?

Any ideas?

Thanks!
Katja
