<django.db.models.query_utils.DeferredAttribute object at 0x000001B24C6E5F60>

Atef Ouerghi
I would like to retrieve the value of a field in ModelAdmin in order to use as a parameter for requets, but I can't get the value from the data base
I get this <django.db.models.query_utils.DeferredAttribute object at 0x000001B24C6E5F60>
Any help

class AlienTaxonomy(models.Model):

class Meta:
db_table = 'taxonomy'
verbose_name = ('Alien Species Taxonomy')
verbose_name_plural = ('Aliens Species Taxonomy')
ordering = ['SpeciesName']

SpeciesName = models.CharField(max_length=100, verbose_name=u"Species Name")
url=models.URLField(verbose_name=u"Link to WORMS")
Authority = models.CharField(max_length=100, verbose_name=u"Authority")
kingdom = models.CharField(max_length=100, verbose_name=u"Kingdom")
Phylum = models.CharField(max_length=100, verbose_name=u"Phylum")
Class = models.CharField(max_length=100, verbose_name=u"Class")
Order1 = models.CharField(max_length=100, verbose_name=u"Order")
Family = models.CharField(max_length=100, verbose_name=u"Family")
Genus = models.CharField(max_length=100, verbose_name=u"Genus")

def __str__(self): # __unicode__ on Python 2
return self.SpeciesName


def
get_Aphia(ModelAdmin, request, queryset):

if request.method == 'POST':
species = SpeciesName



for Aliens in queryset:

req = requests.get('http://www.marinespecies.org/rest/AphiaIDByName/'+ str(species) + '?marine_only=true')

body = json.loads(req.content)

queryset.update(url=body)

#Aliens.save()

get_Aphia.short_description = 'Check by WoRMS'



class TaxonomyAdmin(admin.ModelAdmin):
list_per_page = 30
list_filter = ('SpeciesName', 'Authority','url','kingdom', 'Phylum', 'Class', 'Order1', 'Family','Genus')
list_display = ['SpeciesName', 'url','Authority','kingdom', 'Phylum', 'Class', 'Order1', 'Family','Genus']
fields = ['SpeciesName']
actions = [get_Aphia, get_classification, get_synonyms]

This mailing list is for the development of Django itself, not for support. Use the django-users mailing list for that, or IRC #django on freenode, or a site like Stack Overflow.
