Update a queryset in django
I need to update the data on the database once I get all the values of that data with current DateTime..i.e My Model: class Load_Balancing(models.Model): instance_name = models.CharField(max_length=100) instance_visit = models.DateTimeField(null=True) sequence = models.IntegerField() I want to get the value with the last sequence number inserted in the database and update its time to the current time. I tried: instances = Load_Balancing.objects.all().order_by("-sequence")[:1] a = Load_Balancing.objects.filter(sequence=instances.sequence).update(instance_visit= datetime.datetime.now()) But it's not working. -
Why is my form not being saved to admin database?
Hi I'm trying to develop a website for an online store using Django. I want to use Ajax to handle the view of my checkout form after it has been submitted. After the form is submitted, I want it to go to : return HttpResponseRedirect(reverse(str(next_page))+"?address_added=True") , i.e http://127.0.0.1:8000/checkout/?address_added=True But for some reason, it is not going there. Rather it's being redirected to http://127.0.0.1:8000/checkout/?csrfmiddlewaretoken=W4iXFaxwpdtbZLyVI0ov8Uw7KWOM8Ix5GcOQ4k3Ve65KPkJwPUKyBVcE1IjL3GHa&address=123+Main+Street&address2=&state=MA&country=USA&zipcode=55525&phone=%28877%29+314-0742&billing=on As a result, the form data is also not getting saved. I was thinking if it were because of the new version of Django. What I want to do is that after they submit the place order button, the form is going to be None, i.e disapper and then I would add a credit card form there for payment. But it is not happening. What is wrong here? Can anyone please help me out of this or is there a better way to do this? My forms.py: class UserAddressForm(forms.ModelForm): class Meta: model = UserAddress fields = ["address", "address", "address2", "state", "country", "zipcode", "phone", "billing"] My accounts.views.py: def add_user_address(request): try: next_page = request.GET.get("next") except: next_page = None if request.method == "POST": form = UserAddressForm(request.POST) if form.is_valid(): new_address = form.save(commit=False) new_address.user = request.user new_address.save() if next_page is not None: … -

How do I change the location to where pip install site-package modules?

Keep Slug uniques when they depend on another slug
My webpage has some urls like this, /<slug1>/<slug2>/slug3>/, where the slugs belong to distinct models respectively. Basically I cannot allow for slug1 to be repeated at anypoint, and that's easy I'll just use unique_slugify. However slug2 must be unique if and only if it belongs to the same slug1, so pizza/pepperoni/ and pizza/pepperoni/, are not valid if each "pepperoni" slug belongs to a different object. However if there were 2 distinct objects such that the final slug ended up being pizza/pepperoni/ and pasta/pepperoni/ that would be absolutely fine. However making the SlugField in the model be unique=True, won't allow for the slugs to be the same even if they do belong to different objects. The only workaround I've thought for this is making each slug directly dependent on its previous one, such that slug2=unique_slugify(slug1+object2.name), and then slug3=unique_slugify(slug2+object3.name). Still this makes the urls way less intuitive as you could still end up with urls that would be the same on slug3, and would need numbers or stuff like taht to be different. For instance: /spa/spanish/spanishsausage/ and /span/spanishsau/spanishsausage/, where slug3 is identical in both. Therefore is there anyway I can make slugs such that slug3 only has to be unique for 2 … -

Function doesn't call another function in Django views
I have a chain of functions, that i need to execute consistently like this: user_profile() -> deposit_counter() -> test() However, my test function is not executing. What is wrong with it? def user_profile(request): try: print('deposit counter') deposit_counter(request) except Profile.DoesNotExist: return render(request, "../templates/profile.html") def deposit_counter(request): deposit_object = Deposits.objects.get(id=request.user.profile.deposits.id) deposit_type_object = getattr(deposit_object, 'deposit_type') if deposit_type_object == Deposits.DEPOSIT_TYPE[0][0]: tax = 13 Deposits.objects.update(tax_rate=13) percentage = 0.11 print('i am hit') test(request, percentage, tax) def test(request, percentage, *args): deposit_object = Deposits.objects.get(id=request.user.profile.deposits.id) deposit_value_object = getattr(deposit_object, 'deposit_value') deposit_creating_date = getattr(deposit_object, 'deposit_creating_date') deposit_end_date = getattr(deposit_object, 'deposit_end_date') deposit_income = deposit_value_object * (percentage/100) * (args / 100) Deposits.objects.update(temporary_deposit_income=deposit_income, temporary_total_income=(deposit_income + deposit_value_object)) print('I am here') if deposit_creating_date == deposit_end_date: Deposits.objects.update(deposit_income=deposit_income, total_income=(deposit_income + deposit_value_object), temporary_deposit_income=None, temporary_total_income=None) Account.objects.update(current_balance=(deposit_income + deposit_value_object)) -
Django: all auth create account with email - unique constraint failed. Display message instead of giving an error
I am using djnago all-auth to create custom user accounts. When creating an account with email and password, if account with a email already exits it gives an error (UNIQUE constraint failed: account_emailaddress.email) but I would like to display message that an account with this email already exists instead of throwing an error. What is the best way to handle this? In general I would use AJAX to verify and display message for my own views but I do not know how to deal here with django all-auth package. -
PostgreSQL Function not working with WHERE clause
I am trying to make a function in postgres to make my queries faster compared to Django ORM. But the problem I am facing is results are coming when there is no WHERE clause in the query. This is the function and its call which yeilds 0 rows: CREATE OR REPLACE FUNCTION public.standard_search(search_term text, similarity_to integer) RETURNS TABLE(obj_id integer, app_num integer, app_for text, similarity integer) LANGUAGE 'plpgsql' AS $BODY$ DECLARE similarity integer; BEGIN RETURN QUERY SELECT mark.id, mark.app_num, mark.app_for::text, levenshtein($1, focusword.word) AS similarity FROM mark INNER JOIN focusword ON (mark.id = focusword.mark_id) WHERE similarity <= $2 ORDER BY similarity, mark.app_for, mark.app_num; END $BODY$; select * from public.standard_search('millennium', 4) This is the function and its call which is giving me results but is slow as the filtering is done in the function call: CREATE OR REPLACE FUNCTION public.standard_search(search_term text, similarity_to integer) RETURNS TABLE(obj_id integer, app_num integer, app_for text, similarity integer) LANGUAGE 'plpgsql' AS $BODY$ DECLARE similarity integer; BEGIN RETURN QUERY SELECT mark.id, mark.app_num, mark.app_for::text, levenshtein($1, focusword.word) AS similarity FROM mark INNER JOIN focusword ON (mark.id = focusword.trademark_id) ORDER BY similarity, trad.app_for, mark.app_num; END $BODY$; select * from public.standard_search('millennium', 4) where similarity <= 4 Can anyone shed some light on what is … -
Django/Python - How do I get a count of records in a model where an @property function is True?
I'm very new to python and django and I'm working on a version of the locallibrary project to learn some concepts. I've created a model with an @property to show when an item is overdue: @property def overdue(self): is_overdue = False if (datetime.date.today() > self.due_date) and self.status != 'c': is_overdue = True return is_overdue I would like to get a count of all items where overdue=True. In templates I can use 'overdue' as if it were a field, however, trying to use is in a view like this... num_actions_overdue = Action.objects.filter(overdue='True').count() ...throws an error: Cannot resolve keyword 'overdue' into field. Is there a simple way to count all overdue records? Thanks in advance for any help! -
