I have the following models -
class Jobdtl(models.Model):
jobdtl_id = models.IntegerField(primary_key=True)
jobdtl_cmd = models.TextField(blank=True)
jobdtl_envfile = models.TextField(blank=True)
jobdtl_retnsn = models.SmallIntegerField(blank=True, null=True)
jobdtl_allowadhoc = models.CharField(max_length=1, blank=True)
jobdtl_waitop = models.CharField(max_length=1, blank=True)
class Meta:
managed = False
db_table = 'jobdtl'
class Jobmst(models.Model):
jobmst_id = models.IntegerField(primary_key=True)
jobmst_prntid = models.IntegerField(blank=True, null=True)
jobmst_active = models.CharField(max_length=1, blank=True)
jobmst_evntoffset = models.SmallIntegerField(blank=True, null=True)
jobmst_name = models.TextField(blank=True)
jobmst_owner = models.IntegerField(blank=True, null=True)
jobmst_crttm = models.DateTimeField()
jobdtl_id = models.ForeignKey('Jobdtl', db_column='jobdtl_id', related_name='mstdtl', blank=True, null=True)
jobmst_lstchgtm = models.DateTimeField(blank=True, null=True)
def __unicode__(self):
return self.jobmst_name
class Meta:
managed = False
db_table = 'jobmst'
I'm trying to generate a json similar to what we have here -
http://stackoverflow.com/questions/19709101/django-rest-framework-multiple-models
using the steps here -
http://stackoverflow.com/questions/16793608/how-to-write-a-django-rest-framework-serializer-field-to-merge-data-from-gener
These are my serializers -
class JobmstSerializer(serializers.ModelSerializer):
class Meta:
model = Jobmst
class JobdtlSerializer(serializers.ModelSerializer):
jobmst_id = JobmstSerializer(many=True)
class Meta:
model = Jobdtl
And this is my view
class ResultsList(ListAPIView):
def list(self, request, *args, **kwargs):
jobmstquery = Jobmst.objects.using('Admiral').all()
jobdtlquery = Jobdtl.objects.using('Admiral').all()
results = list()
entries = list(chain(jobmstquery, jobdtlquery)) # combine the two querysets
for entry in entries:
type = entry.__class__.__name__.lower() # 'jobmst', 'jobdtl'
if isinstance(entry, Jobmst):
serializer = JobmstSerializer(entry)
dictionary = {'type': jobmst, 'jobmst_id': jobmst_id, 'jobmst_type': jobmst_type, 'jobmst_prntid': jobmst_prntid, 'jobmst_active': jobmst_active, 'evntmst_id': evntmst_id, 'jobmst_evntoffset': jobmst_evntoffset, 'jobmst_name': jobmst_name, 'jobmst_mode': jobmst_mode, 'jobmst_owner': jobmst_owner, 'jobmst_desc': jobmst_desc, 'jobmst_crttm': jobmst_crttm, 'jobdtl_id': jobdtl_id, 'jobmst_lstchgtm': jobmst_lstchgtm}

results.append(dictionary)
return Response(results)
I tie it through my URL -
urlpatterns = patterns('TidalDEV.views',
url(r'^TidalDEV/$', 'ResultsList'),
url(r'^TidalDEV/(?P<pk>[0-9]+)/$', 'ResultsList'),
)
But when I hit my URL at http://localhost/TidalDEV/ or http://localhost/TidalDEV/50244/
I get slammed with an error -
Exception Type: TypeError
Exception Value:
__init__() takes 1 positional argument but 2 were given
Exception Location: D:\Python33\lib\site-packages\django\core\handlers\base.py in get_response, line 114
I ended up doing the following and it worked -
class JobdtlSerializer(serializers.ModelSerializer):
class Meta:
model = Jobdtl
class JobmstSerializer(serializers.ModelSerializer):
jobdtl_id = JobdtlSerializer()
class Meta:
model = Jobmst
then connected with the variation of the default views -
#csrf_exempt

return HttpResponse(status=204)
That allowed me to get from the 2 separate models. It's unformatted and ugly but proves it can be done. Need to figure out how to link more than these 2 models now (I have 5 minimum).

can you modify your swagger_auto_schema decorator like this?
#swagger_auto_schema(
methods=['post',],
request_body=EventSerializer )
All you need to do is place the #swagger_auto_schema on the top. To help it display the parameters create a serializer for it. This way, you only have to change the serializer in the future keeping everything in one place.

In your resources, while defining fields, you need to include id field in the list. So change JobResource to the following:
class JobResource(resources.ModelResource):
class Meta:
model = Job
fields = ('id', 'aplink', 'job_num', 'description')
If you have defined a custom id field, then you will need to provide:
import_id_fields = ('your_id_field')

Try using SlugRelatedField instead of Field.
Like so:
class AddAuctionsSerializer(serializers.ModelSerializer):
# instead of this:
# author_id = serializers.Field(source='author.id')
# do this:
author = serializers.SlugRelatedField(queryset=User.objects.all(), slug_field='id', write_only=True)
class Meta:
model = Auction
fields = ["title", "desc", "image","location","min_value","date_added","author"]
# don't put 'author_id' in read_only, because creating is "writing"
# also note that 'author.id' is invalid field
# read_only_fields = ('author','id','author_id','author.id')
read_only_fields = ('id')
# Get the current user from request context
def validate_author(self, value):
return self.context['request'].user
I had the same problem.
You can solve it by overwriting the create method of AddAuctionsSerializer and manually defining instance.author, or by passing the parameter author = request.user, to the save method of AddAuctionsSerializer,

Located in the model StokGiris.miktari and Stok.Cikis.miktari fields need calculation. Total = StokGiris.miktari - StokCikis.miktari and I want to list the records.
If I understand your question correctly, you want to aggregate the values of miktar of both models and subtract them from each other. You can do it with Django built-in aggregation:
from django.db.models import Sum
total = StokGiris.objects.all().aggregate(Sum('miktar')) - StokCikis.objects.all().aggregate(Sum('miktar'))
As for listing the records... Not really sure what you mean again, but some ways to "list the records":
# Just a list of DB items
list_of_stokgiris = list(StokGiris.objects.all())
# Serialized list of dictionaries with the DB values
list_of_stokcikis = StokCikis.objects.values() # You can add an argument to specify which fields you want to be serialized
# Serialized list of tuples with DB values
# I.e. [('Filipp',), ('Artjom',), ('Marat',)]
list_of_urunler = Urunler.objects.values_list('adi') # Same here for the argument. Multiple args are also supported.

This my code, Why I am getting the 404 error? What I have to do for fix this error?
you cannot do
return search_results(request, slug)
do rather this redirect
return redirect(reverse('classifieds_browse_search_results', kwargs={'slug':slug}))
dont forget to import
from django.core.urlresolvers import reverse
from django.shortcuts import redirect
