I have made two models which are as follows:
class itemsSearched(models.Model):
searched_items = models.CharField(max_length=120)
def __str__(self):
return self.searched_items
class VisitorInfo(models.Model):
user_id = models.CharField(max_length=120)
items_searched = models.ManyToManyField(itemsSearched,blank=True)
I want to save value tshirt in visitorInfo model. Here is the view for this
def get_req(request):
event = request.GET['e']
if event == 'pv':
x_forwarded_for = request.META.get('HTTP_X_FORWARDED_FOR')
if x_forwarded_for:
ip = x_forwarded_for.split(',')[-1].strip()
else:
ip = request.META.get('REMOTE_ADDR')
check_user(request,ip)
elif event == 'pp':
visitor = VisitorInfo.objects.get(user_id=request.GET['duid'])
visitor.active = True
print(visitor.active)
visitor.save()
elif event == 'ue':
u_id = request.GET['duid']
tz = request.GET['tz']
url = request.GET['url']
link = request.GET['ue_pr'] #ue_pr is the property of unstructured event of the type json.
o = json.loads(link)
print(o)
if(o['data']['data']['elementId']=='nf-field-1'):
name = o['data']['data']['value']
print("Name: "+ name)
visitor= VisitorInfo.objects.get(user_id=u_id)
visitor.name = name
visitor.save()
elif(o['data']['data']['elementId']=='s'):
searched_item = int(o['data']['data']['value'])
print("Searched: "+ searched_item) #6
print("Type of searched_item " + type(searched_item)) #7
visitor= VisitorInfo.objects.get(user_id=u_id)
visitor.items_searched.add(searched_item)
visitor.save()
For the sake of clarity I printed 'o' which is a python dictionary parsed from json.Here is the what i have got
{'schema': 'iglu:com.snowplowanalytics.snowplow/unstruct_event/jsonschema/1-0-0', 'data': {'schema': 'iglu:com.snowplowanalytics.snowplow/change_form/jsonschema/1-0-0', 'data': {'formId': 'FORM', 'elementId': 's', 'nodeName': 'INPUT', 'type': 'search', 'elementClasses': ['search-field'], 'value': 'tshirt'}}}
I want to save the value 'tshirt' in visitor info but i am getting the following error.

Like the error says, you can't add a string to a many-to-many field. You need to an object of the related model.
I haven't quite understood what you're trying to do, but I suspect you want to get or create an ItemSearched model for "t-shirt", and then add that.
item, _ = itemsSearched.objects.get_or_create(searched_items=searched_item)
visitor = VisitorInfo.objects.get(user_id=u_id)
visitor.items_searched.add(item)
Note, you don't need to save visitor after only modifying its m2m field.

I wanna do a simple recommendation system based on users' Animals that they added. I want to show only products of a category, that's been mapped in "zwierzeta" dictionary. So basically if user has chosen that he has a horse (which is id 1, i want to show only products that have category 4) Also if user has more than 1 animals, i want to show them randomly from list of categories id. The logic seems to be fine, im just new at django and i have no idea how to actually iterate through the querysets and how to get a value(animal) from a particular queryset. The get method doesnt work. Do you have any idea how to get a particular value from a queryset?
class MyAnimal(models.Model):
name = models.CharField(max_length=256)
animal = models.ForeignKey(Animal, on_delete=models.CASCADE, null=False)
class ProductInStore(models.Model):
product = models.ForeignKey('Product', on_delete=models.CASCADE)
class Product(models.Model):
product_category = models.ManyToManyField(EcommerceProductCategory)
def list(self, request):
ProductCategoryAnimal.objects
qs = MyAnimal.objects.filter(user=self.request.user)
if qs:
for q in qs:
categories = []
get_category = ProductCategoryAnimal.objects.values_list('category_id', flat=True).get(animal_id=q.animal_id)
categories.append(get_category)
print(categories)
result = ProductInStore.objects.filter(
product__product_category__id=random.choice(categories)
)
else:
result = ProductInStore.objects.all()[:1]
return result.order_by('?')[:1]

You can simplify this to:
def list(self, request):
zwierzeta = {1 : 4, 6: 5, 8: 6, 9: 6, 4: 3}
qs = MyAnimal.objects.filter(user=self.request.user)
if qs:
category=random.choice([zwierzeta[q.animal_id] for q in qs])
result = ProductInStore.objects.filter(
product__product_category__id=category
)
else:
result = ProductInStore.objects.all()
return result.order_by('?')[:1]
But using a dictionary with hardcoded items looks odd: it means you need to know the primary keys in advance and it is hard to later add new categories since it requires deploying a new software version. It might be better to model the relation between a category and an animal as a ManyToManyField or equivalent.
I want to dynamicly create some filter criteria depending on the url query params.
For this I created a nested Django Q-Object which looks like:
query = <Q: (AND: (OR: region=30, region=39), name__endswith=Hannover, zip_code=30165)>
Now I want to pass this Q object to Model-Filter
Eort.objects.filter(query)
Thereby I get a ValueError : too many values to unpack (expected 2)

Does anybody know how to solve this problem?
This is how I created the Q-Object:
def or_operator(self, key, qlist):
if qlist:
result = Q()
result.connector = Q.OR
for i in qlist:
if i == '':
continue
if i[0] == '%' and i[-1] == '%':
result.add(Q('{0}__{1}={2}'.format(key, 'contains', i[1:-1])), Q.OR)
elif i[0] == '%' and not i[-1] == '%':
result.add(Q('{0}__{1}={2}'.format(key, 'startswith', i[1:])), Q.OR)
elif not i[0] == '%' and i[-1] == '%':
result.add(Q('{0}__{1}={2}'.format(key, 'endswith', i[:-1])), Q.OR)
else:
result.add(Q('{0}={1}'.format(key, i)), Q.OR)
return result
query = Q()
query.connector = Q.AND
for key in params:
if key in ['lat', 'lng', 'name', 'street', 'zip_code', 'city', 'region']:
val = params.get(key, None).split(',')
query.add(self.or_operator(key, val),Q.AND)
You should not work with ={2}. A Q object is not a string of the form foo=bar, it is in essence a 2-tuple with as first element a string that is the "key" which is the field and optionally some lookups, and as second element a value, but that value can be a string, datetime object, etc. You thus construct the Q object with:
if i[0] == '%' and i[-1] == '%':
result.add(Q((f'{key}__contains', i[1:-1])), Q.OR)
elif i[0] == '%' and not i[-1] == '%':
result.add(Q((f'{key}__startswith', i[1:])), Q.OR)
elif not i[0] == '%' and i[-1] == '%':
result.add(Q((f'{key}__endswith', i[:-1])), Q.OR)
else:
result.add(Q((key, i)), Q.OR)

The model of 'Currency' is:
class Currency(models.Model):
currency_name = models.CharField(max_length=100)
currency_value_in_dollars = models.FloatField()
currency_value_in_dollars_date = models.DateTimeField()
def __str__(self):
return self.currency_name
Why can't I filter by 'currency_value_in_dollars_date'? check if the currency value has been updated within the last hour.
You can not simply uses a list of two values to filter. If you for example want to retrieve all elements in between you can work with a __range lookup [Django-doc]:
from django.utils.timezone import now
current_time = now()
up_to_date_currency = Currency.objects.filter(
currency_value_in_dollars_date__range=(
current_time-timedelta(hours=1),
current_time
)
).order_by('-currency_value_in_dollars_date')[:len(coins_ids)]
This will thus retrieve all Currency objects between an hour ago and now.
If by
check if the currency value has been updated within the last hour
you mean you want to filter all rows up to 1 hour ago, then replace
currency_value_in_dollars_date=
[datetime.now(), timedelta(hours=1)]
with (notice __gte)
currency_value_in_dollars_date__gte=datetime.now() - timedelta(hours=1)
If you want to filter by array, then you'd have to either use JSONField to match value, or use __in to execute SQL in. Otherwise, you can't filter by array, so what you did is basically invalid.
Depending on your settings, you should probably use timezone.now() from django instead of datetime.

Any help would be appreciated, thank you!
The error likely happens because event_date ends up with the value False, which happens because there was no value for 'event_date' in request.GET.
According to the docs of Client.get(), you have to pass a dict with the GET/POST parameters of the request, not using kwargs.
Try by changing this line (which is using kwargs):
request = c.get('/profile/1/check_availability/', event_date='1999-12-20')
to this (now using a dict as the second parameter)
request = c.get('/profile/1/check_availability/', {'event_date': '1999-12-20'})
I am trying to get a specific user in Django via email filtering using default user model. I am doing the following in my views.py but it is not working:
def shareCode(request):
if request.method=="POST":
email = request.POST.get("mail")
print(email)
id = int(request.POST.get('id'))
user = User.objects.get(email = email)
obj = Code.objects.get(pk=id,user = user.id)
res = {"shared":"fasle"}
obj2 = Code(name=obj.name,code=obj.code,shared=True)
obj2.save()
res = {
"shared":True
}
return HttpResponse(json.dumps(res))
models.py
class Code(models.Model):
name = models.CharField(max_length=255)
code = models.TextField()
user = models.ForeignKey(User,on_delete=models.CASCADE)
shared = models.BooleanField(default=False)
but its getting be following error

Any help will be appreciated
You can retrieve an object from models using exact match.
e.g:
user = User.objects.get(email__exact='usermail#example.com')
This would generate SQL that looks like this:
SELECT ... WHERE email = 'usermail#example.com';
