For loop issue writing multiple lines to database - python
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.

I want to get a result object depending on the study_id I give
Result depends on Exam, Exam depends on Course and Course depends on study
Thanks in advance
You can follow relationships in queries by using the double underscore notation Result.objects.filter( exam_id_exam__course_id_course__study_id_study__id=study_id ) For what it's worth: you have an odd naming convention for your foreign keys, usually a foreign key to a model named Exam would be named exam, you are already setting db_column for each foreign key so you don't need to name them this way. If you changed their names to be the model name lowercase it would look like this which is probably more readable Result.objects.filter(exam__course__study__id=study_id)

You can then put extra fields on the intermediate model. The intermediate model is associated with the ManyToManyField using the through argument to point to the model that will act as an intermediary. Let me finish with a little advice, it is true, 'These are the relevant classes of my app', but you can illustrate this sample with just few fields.

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 TbMouvementinit(models.Model): id = models.AutoField(db_column='Id', primary_key=True) # Field name made lowercase. dateheurecreat = models.TextField(db_column='DateHeureCreat') # Field name made lowercase. dateheureclot = models.TextField(db_column='DateHeureClot', blank=True, null=True) # Field name made lowercase. id_pesee = models.BigIntegerField(db_column='Id_Pesee') # Field name made lowercase. id_proteine = models.BigIntegerField(db_column='Id_Proteine', blank=True, null=True) # Field name made lowercase. id_humidite = models.BigIntegerField(db_column='Id_Humidite', blank=True, null=True) # Field name made lowercase. id_espece = models.BigIntegerField(db_column='Id_Espece', blank=True, null=True) # Field name made lowercase. id_produit = models.BigIntegerField(db_column='Id_Produit', blank=True, null=True) # Field name made lowercase. id_codeechantillon = models.BigIntegerField(db_column='Id_CodeEchantillon', blank=True, null=True) # Field name made lowercase. id_traitement = models.BigIntegerField(db_column='Id_Traitement', blank=True, null=True) # Field name made lowercase. id_circuit = models.BigIntegerField(db_column='Id_Circuit', blank=True, null=True) # Field name made lowercase. code_source = models.CharField(db_column='Code_Source', max_length=20, blank=True, null=True) # Field name made lowercase. code_destination = models.CharField(db_column='Code_Destination', max_length=20, blank=True, null=True) # Field name made lowercase. nomos = models.CharField(db_column='NomOS', max_length=30, blank=True, null=True) # Field name made lowercase. codesite = models.CharField(db_column='CodeSite', max_length=9, blank=True, null=True) # Field name made lowercase. type_mouvement = models.CharField(db_column='Type_Mouvement', max_length=3, blank=True, null=True) # Field name made lowercase. sous_domaine = models.CharField(db_column='Sous_Domaine', max_length=1, blank=True, null=True) # Field name made lowercase. recolte = models.SmallIntegerField(db_column='Recolte', blank=True, null=True) # Field name made lowercase. espece = models.CharField(db_column='Espece', max_length=9, blank=True, null=True) # Field name made lowercase. code_variete = models.CharField(db_column='Code_Variete', max_length=10, blank=True, null=True) # Field name made lowercase. code_tiers = models.CharField(db_column='Code_Tiers', max_length=9, blank=True, null=True) # Field name made lowercase. num_bl_livreur = models.CharField(db_column='Num_Bl_Livreur', max_length=9, blank=True, null=True) # Field name made lowercase. num_contrat_client = models.IntegerField(db_column='Num_Contrat_Client', blank=True, null=True) # Field name made lowercase. num_oe = models.IntegerField(db_column='Num_OE', blank=True, null=True) # Field name made lowercase. code_transporteur = models.CharField(db_column='Code_Transporteur', max_length=9, blank=True, null=True) # Field name made lowercase. immat_transporteur = models.CharField(db_column='Immat_Transporteur', max_length=10, blank=True, null=True) # Field name made lowercase. poids_charge = models.FloatField(db_column='Poids_Charge', blank=True, null=True) # Field name made lowercase.

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 ?
Django Restful Framework - Limit Results Based on Role/Group
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()
