Django Restful Framework - Limit Results Based on Role/Group - python

I'm trying to build an API in Django Rest Framework (Python 3.x). As a requirement from our b2b partners we can only redistribute their content to certain users. Therefore, I'd like to edit the view to only return certain data based on a users group/role in the system.
For example, I have the following model:
class LocalDeals(models.Model):
deal_id = models.IntegerField(db_column='deal_ID', unique=True) # Field name made lowercase.
deal_url = models.CharField(db_column='deal_URL', max_length=600) # Field name made lowercase.
store_id = models.IntegerField(db_column='store_ID', blank=True, null=True) # Field name made lowercase.
store_online_id = models.IntegerField(db_column='storeOnline_ID', blank=True, null=True) # Field name made lowercase.
store_chain_id = models.IntegerField(db_column='storeChain_ID', blank=True, null=True) # Field name made lowercase.
deal_price = models.FloatField(db_column='dealPrice', blank=True, null=True) # Field name made lowercase.
deal_original_price = models.FloatField(db_column='dealOriginalPrice', blank=True, null=True) # Field name made lowercase.
deal_title = models.CharField(db_column='dealTitle', max_length=256) # Field name made lowercase.
store_name = models.CharField(db_column='storeName', max_length=64, blank=True, null=True) # Field name made lowercase.
image_small = models.CharField(db_column='smallImage', max_length=128, blank=True, null=True) # Field name made lowercase.
image_large = models.CharField(db_column='largeImage', max_length=128, blank=True, null=True) # Field name made lowercase.
store_url = models.CharField(db_column='storeURL', max_length=128, blank=True, null=True) # Field name made lowercase.
provider_name = models.CharField(db_column='providerName', max_length=64, blank=True, null=True) # Field name made lowercase.
provider_logo = models.CharField(db_column='providerLogo', max_length=128, blank=True, null=True) # Field name made lowercase.
user_provider_id = models.IntegerField(db_column='userProvider_ID', blank=True, null=True) # Field name made lowercase.
expiration_date = models.DateTimeField(db_column='expirationDate', blank=True, null=True) # Field name made lowercase.
create_date = models.DateTimeField(db_column='createDate', blank=True, null=True) # Field name made lowercase.
update_date = models.DateTimeField(db_column='updateDate') # Field name made lowercase.
yelp_rating = models.FloatField(db_column='yelp_rating',blank=True, null=True)
yelp_review_count = models.IntegerField(db_column='yelp_review_count',blank=True, null=True)
yelp_rating_img_url = models.CharField(db_column='yelp_rating_img_url',max_length=128, blank=True, null=True)
yelp_url = models.CharField(db_column='yelp_url',max_length=128, blank=True, null=True)
address1 = models.CharField(db_column='address1',max_length=64, blank=True, null=True)
city = models.CharField(db_column='city',max_length=64, blank=True, null=True)
state = models.CharField(db_column='state',max_length=32, blank=True, null=True)
zip = models.CharField(db_column='zip',max_length=10, blank=True, null=True)
country = models.CharField(db_column='country',max_length=32, blank=True, null=True)
latitude = models.FloatField(db_column='latitude',blank=True, null=True)
longitude = models.FloatField(db_column='longitude',blank=True, null=True)
deal_code = models.CharField(db_column='dealCode', max_length=32, blank=True, null=True) # Field name made lowercase.
event_date = models.DateTimeField(db_column='eventDate', blank=True, null=True) # Field name made lowercase.
is_now_deal = models.IntegerField(db_column='isNowDeal', blank=True, null=True) # Field name made lowercase.
business_type = models.IntegerField(db_column='businessType', blank=True, null=True) # Field name made lowercase.
scoring_base = models.FloatField(db_column='scoringBase', blank=True, null=True) # Field name made lowercase.
deal_type = models.CharField(db_column='dealType', max_length=16, blank=True, null=True) # Field name made lowercase.
deal_disclaimer = models.TextField(db_column='dealDisclaimer', blank=True, null=True) # Field name made lowercase.
submit_id = models.IntegerField(db_column='submit_ID', blank=True, null=True) # Field name made lowercase.
deal_date_time = models.DateField(db_column='deal_datetime',blank=True, null=True)
business_type_sub = models.IntegerField(db_column='businessTypeSub', blank=True, null=True) # Field name made lowercase.
class Meta:
managed = False
db_table = 'local_deals'
app_label = 'api'
Which is called by the following view and serializer:
class LocalDealsViewSet(viewsets.ModelViewSet):
"""
API endpoint that allows local_deals to be viewed.
"""
throttle_classes = (UserRateThrottle,)
queryset = LocalDeals.objects.all()
serializer_class = LocalDealsSerializer
class LocalDealsSerializer(serializers.HyperlinkedModelSerializer):
class Meta:
model = LocalDeals
fields = ('deal_id','deal_url','deal_price','deal_original_price','deal_title',
'store_name','image_small','image_large','store_url','provider_name',
'expiration_date','create_date','update_date','address1','city','state',
'zip','country','latitude','longitude','deal_code',
'business_type','business_type_sub','deal_type','deal_date_time',)
If the user is not in the auth_group 'admin' (id 1) then I'd like to restrict the results so that it shows all results except where user_provider_id in [1,3]. How can I do this?


You should override get_queryset() method to restrict results based on admin auth group.
class LocalDealsViewSet(viewsets.ModelViewSet):
"""
API endpoint that allows local_deals to be viewed.
"""
throttle_classes = (UserRateThrottle,)
serializer_class = LocalDealsSerializer
def get_queryset(self):
# check here if 'list' request and user not in admin auth group
if self.action == 'list' and self.request.user not in admin auth_group:
# exclude results with 'user_provider_id' in [1,3]
return LocalDeals.objects.all().exclude(user_provider_id__in=[1,3])
# Otherwise return all results
return LocalDeals.objects.all()

When I select some item
it show this error

Remove the id field from your model, as you have referenced it as a foreign key to the model itself. The id field is automatically generated if no field in the model is explicitly chosen.

How can I add a button inside DetailView template that sends ID to a form?

I have a App called "Properties" and I've created a DetailView that is working. Inside my Properties models I have a Property model and a Bedroom model with a ForeignKey to Property.
#views.py
class PropertyDetailView(DetailView):
template_name = 'properties/property-detail.html'
model = Property
def get_context_data(self, **kwargs):
contacts = ContactsOwner.objects.filter(owner__property=self.object)
context = super().get_context_data(**kwargs)
context['contact'] = contacts
return context
My models.py:
class Property(models.Model):
property_reference = models.CharField(db_column='Property_Reference', max_length=10) # Field name made lowercase.
address = models.CharField(db_column='Address', max_length=250, blank=True, null=True) # Field name made lowercase.
post_code = models.CharField(db_column='Post_Code', max_length=15, blank=True, null=True) # Field name made lowercase.
type = models.CharField(db_column='Type', max_length=25, blank=True, null=True, choices=HOUSE_TYPE_CHOICES) # Field name made lowercase.
bedrooms = models.IntegerField(db_column='Bedrooms', blank=True, null=True) # Field name made lowercase.
bathrooms = models.IntegerField(db_column='Bathrooms', blank=True, null=True) # Field name made lowercase.
usual_cleaning_requirements = models.CharField(db_column='Usual_Cleaning_Requirements', max_length=250, blank=True, null=True) # Field name made lowercase.
notes = models.CharField(db_column='Notes', max_length=500, blank=True, null=True) # Field name made lowercase.
feature_image = models.ImageField(null=True)
class Meta:
db_table = 'Property'
def __str__(self):
return self.property_reference
def get_absolute_url(self):
return reverse("properties:property_detail",kwargs={'pk':self.pk})
class Bedroom(models.Model):
type = models.CharField(db_column='Type', choices=BEDROOM_TYPE_CHOICES, max_length=50)
bed_dimensions = models.CharField(db_column='Bed_Dimension', choices=BED_DIMENSION_CHOICES, max_length=30)
image = models.ImageField(null=True, blank=True)
ensuite = models.BooleanField(default=False)
notes = models.CharField(db_column='Notes', max_length=500, blank=True, null=True) # Field name made lowercase.
property = models.ForeignKey(Property, null=False, on_delete=models.CASCADE, related_name='bedroom')
What I need is to create a button named "Add Bedroom" inside the template "property-detail.html" that sends me to a form with pre filled Foreign Key. Could you please help me on this?

You need to redirect that button submit to a view that gets the required info you want and then redirect that to another template with context the info you received (your Foreign key per se)

For loop issue writing multiple lines to database

The for loop below has an issue when writing to the database. Only the first record is coming through, i believe it's because report_name_sc = reportlist is writing the query set to the database. How can I get it to write a single line for each report_id?
checkedlist = request.GET.getlist('report_id')
reportlist = QvReportList.objects.filter(report_id__in= checkedlist, active = 1).values_list('report_name_sc',flat = True)
for i in checkedlist:
requestsave = QVFormAccessRequest(ntname_id = owner.formattedusername, first_name = owner.first_name, last_name = owner.last_name, coid = owner.coid, facility = owner.facility, title = owner.title
,report_id = i, report_name_sc = reportlist, accesslevel_id = '7', phi = '1', access_beg_date = '2017-01-01', access_end_date = '2017-01-31')
requestsave.save()
Models.py added as requested, checked list is a collection of check boxes getting report_id:

Your QVFormAccessRequest model specifies ntname to be a primary key. So, there cannot be to model instances with the same primary key.
In your loop, you are iterating over checkedlist, but you always set the same ntname_id, so you are overwriting the previous object.
I suspect that you need to change your model to support what you want to achieve. Maybe, it is enough to remove the primary key constraint from ntname and let Django create a surrogate key (artificial key) for you.

Django models and join sql tables

i wanted to try using django instead of having to call my stored procedure on the DB.
So i created a new model, taking informations from two differents models

class ResumeMvtActif(models.Model):
mvt = models.ForeignKey(TbMouvementinit)
espece = models.ForeignKey(TbEspece)
And then call it by using just
mouvements = ResumeMvtActif.objects.all()
But of course i get a Database error because i don't really have a ResumeMvtActif table.
How can i proceed to make this work ? do i have to create an extra table on my DB ? Is there a trick to tell Django that it's not a real table and just a join of two tables ?

Can't update existing record in django

I need to update existing recode in the database.I'm using mysql.

def __unicode__(self):
return self.su_name
class Meta:
managed = False
db_table = 'su_surey'
i didn't use any forms in my web application. In my view.py i have this
if request.method == 'POST':
date=request.POST.get('dates','').split('-')
survey_data=SuSurey.objects.get(id=survey_id)
survey_data.su_name=request.POST.get('Name','')
survey_data.description=request.POST.get('Description','')
survey_data.duration=request.POST.get('Duration','')
survey_data.audience=request.POST.get('Audience','')
survey_data.start_date=date[0]
survey_data.end_date=date[1]
survey_data.update_date=datetime.datetime.today()
survey_data.update_by=request.session['user_login_data']['id']
try:
survey_data.full_clean()
survey_data.save(update_fields=['su_name','description','duration','audience','start_date','end_date','update_date','update_by'])
messages={'success':'Successfuly data added'}
url = reverse('addQuestionSurveys', kwargs={'survey_id': survey_id })
return HttpResponseRedirect(url)
except ValidationError as e:
messages={'error':e.messages}
return render(request, 'pages/forms/newSurvey.html',{'dept_data': dept_data,'messages': messages},context_instance=RequestContext(request))
when i add data Django did update the recode that is find by survey_id recode. it will add new recode to database.how can i fix this problem ? need a quick help thank you.
