Graphene-django - Mutating types with enums
So, I have the following model: class Semester(models.Model): course = models.ManyToManyField(Course, through='CourseSemester') class SemesterType(models.TextChoices): A = 'A', 'Winter' B = 'B', 'Spring' SUMMER = 'SU', 'Summer' name = models.CharField( max_length=200, choices=SemesterType.choices, default=SemesterType.A, ) year = models.IntegerField() I try to add a mutation to add a new semester. Graphene-django seems to automatically generate an Enum field for me, but how can I get it inside the arguments? According to the github issues, something like SemesterType._meta.fields['name'] should work, but I can't get it right, even with wrapping it inside graphene.Argument. It is possible to tell Graphene not to convert it to Enum, however I'd rather avoid that if possible. Any clue how to get that right? -

Extract hours & seconds from Django Interval
I have the following Django PostgreSQL query that calculates an interval; querySet = dbname.objects.all().annotate(duration=Func(F('date_start'), F('date_end'), function='age')) which gives me a date interval, evaluated as a timedelta when .values() is called. Now I'd like to further annotate the query to extract the hours & seconds. Tried django.db.models.functions.Extract, django.db.models.functions.Cast, but can't seem to find a solution. querySet.annotate(hours=Extract('duration', 'hour')) ProgrammingError: function pg_catalog.timezone(unknown, interval) does not exist querySet.annotate(seconds=Cast('duration', DateTimeField())) ProgrammingError: cannot cast type interval to timestamp with time zone -
Phoenix (Elixir) Error running test suite
I have inherited a web project with a backend written in Elixir using the Phoenix framework. I am a Python (Django) developer by trade and new to Elixir. There is 0 test coverage on this project, so I thought that would be a good place to start and get familiar with Elixir and Phoenix. But I get an error message running mix test before I can even get started. 16:27:35.818 [info] Application tzdata started at :nonode@nohost ** (Mix) Could not start application cowboy: exited in: :application.cowboy({:description, 'Small, fast, modular HTTP server.'}, {:vsn, '1.1.2'}, {:id, 'git'}, {:modules, [:cow_uri, :cowboy, :cowboy_app, :cowboy_bstr, :cowboy_clock, :cowboy_handler, :cowboy_http, :cowboy_http_handler, :cowboy_loop_handler, :cowboy_middleware, :cowboy_protocol, :cowboy_req, :cowboy_rest, :cowboy_router, :cowboy_spdy, :cowboy_static, :cowboy_sub_protocol, :cowboy_sup, :cowboy_websocket, :cowboy_websocket_handler]}, {:registered, [:cowboy_clock, :cowboy_sup]}, {:applications, [:kernel, :stdlib, :ranch, :cowlib, :crypto]}, {:mod, {:cowboy_app, []}}, {:env, []}) ** (EXIT) :already_loaded And this is where, I am hoping, my ignorance of Elixir and Phoenix is hindering my debugging capability. Is this tzdata that is throwing this error and not letting the test suite load properly? Any direction or insight is appreciated. -
What happens after Django clean method but before commit?
I am using an awesome library called Django Auditlog. It tracks what changes occurred to an object. For model Book if I changed the Author name from 'John' to 'Mary' it records the before value (John), after value (Mary), when it occurred, and what user made the change. It's working except that it is detecting changes that aren't changes for some of my decimal fields. It thinks a change occurs anytime I save this model: it thinks that I started with .00 and changed it to .0. But .00 is the existing value and I didn't change anything. I just saved() the record. I checked the output of the form itself in the clean() method: services_sub_total 44.00 sum_payments 33.00 And then in the database: I just can't figure out where/why this is detecting only one zero in the decimal place - I'm not seeing that .0 anywhere. So I'm wondering what is happening between the clean() method and the commit that might be truncating the .00 to .0 where Auditlog might be incorrectly detecting a change? -
How to correct CORS errors when redirecting to client from server
I have a django server and react client. My app has been making calls, unabated, to the server for various data I have stored to redux state. Furthermore, I have an authorization flow with an external API achieved via a link (not fetch request) to my backend and then, after obtaining the token, redirects back to my front end. All no problem. The issue comes when I try to refresh my token via get request to my backend. That all works, but then when my backend tries to redirect to my front end I get a CORS error: Access to XMLHttpRequest at 'http://localhost:3000/users/1/.../' (redirected from 'http://localhost:8000/api/callback?refresh_token=....') from origin 'http://localhost:3000' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. How do I deal with this? Again, note that the redirect works just fine when I initially authorize the user via the external API, it's almost the exact same flow. That's why I am confused about this error. -

ForeignKey child objects disappeared from table
So for some reason, when I refreshed my api view today the child objects in my model disappeared from the following JSON object: { "id": 1, "title": "test movie", "date": "2020-09-02", "start_date": "2020-09-23", "end_date": "2020-09-24", "location": "Manhattan", "overview": "Adrian", "studio": "Ghibli", "poster": "http://127.0.0.1:8000/media/", "genre": "Horror", "status": "Paid", "job_type": "Fulltime", "user": 1 }, Initially I had right after "id" an indented section "listing" with all the children objects. I've checked my models to make sure that I didn't accidentally delete anything, and I can't quite figure out what went wrong. user_applications is the many to one (Listings) class User_applications(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.PROTECT, default="1") listing = models.ForeignKey(Listings, on_delete=models.CASCADE, default="1", related_name="listing") ... class Listings(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.PROTECT, default="1") ... -
DRF with TokenAuthentication - Authentication credentials were not provided

Access request.GET or inject a variable in Django's auth login/registration form
I have a custom form using Django's auth library and I want some users to click on a link to login/register that will pre-populate the email field, without them having to enter their email (avoid entering it manually and make sure the user uses the email we have on file). A link like this: /account/login?email=name@domain.com However on the receiving page, I can't use this as Django doesn't permit in templates: <input type="text" name="username" placeholder="Email" class="form-control" required="" value="{{ request.GET.get('email', '') }}"> If there is a way to inject a variable in Django's auth template, I don't know how since the view is not accessible. Is there a way to access request.GET.get() in the templates, or is there a better way to do this? -
What do they mean when they are saying for you to put Authorization (eg. token) in header of each request?
I am using Django and doing calls for API. I have not used headers for Django before. Am I creating a header variable?

Can someone give me an example? Thanks. -

How to sort a query based on another model in Django

I have been trying to get this working below, but I feel like there is much easier way of accomplishing this, Any help is appreciated class MaintenanceAgeList(LoginRequiredMixin,TemplateView): template_name = 'maintenance_list.html' def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) maintenanceList = [] assets = Assets.objects.filter(retire = False) today = timezone.now().date() for asset in assets: maintenance = Maintenance.objects.filter(assetID_id = asset.id, complete =True,).order_by('-dateCompleted') if maintenance.count() > 0: asset['maintDate'] = (maintenance[0].dateCompleted).date() maintenanceList.append(asset) asset['days'] = (today - lastMaintenance[0].dateCompleted.date()).days else: asset['maintDate'] = today - timedelta(days=365) asset['days'] = 365 maintenanceList.append(asset) maintenanceList = maintenanceList.sort(key=lambda r: r.maintDate) context['items'] = maintenanceList return context -
How to use cleaned_data before form validation condition?
I wanted to use cleaned_data['username'] before form.is_valid() condition as shown in the code. I want to get the value from Django form field and check in database if the username exist or not. But its giving me error " Form object has no attribute cleaned_data" how should I solve this or is there any other way to get value from Django form? view.py def RegistrationView(request): form=Registration_Form() if request.method=='POST': print("In Post") form=Registration_Form(request.POST) username=form.cleaned_data['username'] print(username) if form.is_valid(): form.save() return redirect('login_view') else: # messages.error(request,"Form is Invalid!") return redirect('registration_view') else: return render(request,'registration.html',{'form':form}) model.py class User_Registration(models.Model): company_name=models.CharField(max_length=250,blank=False) username=models.CharField(max_length=10,primary_key=True,unique=True,blank=False) password=models.CharField(max_length=10,unique=True,blank=False) email=models.EmailField(max_length=250,blank=False) forms.py class Registration_Form(forms.ModelForm): class Meta: model=User_Registration fields=('company_name','username','password','email') widgets={ 'company_name':forms.TextInput(attrs={'class':'form-control input-sm'}), 'username':forms.TextInput(attrs={'class':'form-control'}), 'password':forms.PasswordInput(attrs={'class':'form-control'}), 'email':forms.EmailInput(attrs={'class':'form-control'}), } -
How to change/ insert the djnago finite state machines on fly from terminal window
I have below a.py djnago finite state machine program: from django.db import models from django_fsm import transition, FSMIntegerField from django_fsm import FSMField, transition import os os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings") import django django.setup() from django.core.management import call_command class Order(models.Model): STATUS_GO = 0 STATUS_COME =1 STATUS_CHOICES = ( (STATUS_GO, 'GO'), (STATUS_COME,'come') ) product = models.CharField(max_length=200) status = FSMIntegerField(choices=STATUS_CHOICES, default=STATUS_GO, protected=True) @transition(field=status, source=. [STATUS_GO], target=STATUS_COME) def walk(self): print("Target moved") I would run above program as : Press F5. >>> State= order() >>> State.walk # input >>> Target moved # output I would like understand by any chance, do djnago /python provide opportunities to insert STATES like ( STATUS_HOLD, STATUS_JUMP) from terminal window, in addition to already available. So that these news get positioned in programs. Any possibility. Thanks. -
Is the OS the reason this Django docker file fails to build?
Getting on boarded onto a project that says it's built with Linux, Python 2.7 and Bash. My work computer only has mac os installed and I'm trying to build this container without having to install Linux but I might have to. Everything is working as intended until I reach this error: Step 28/31 : RUN export COLLECTSTATIC=local && python manage.py collectstatic --settings=settings.{__SETTINGS__} --link --no-input ---> Running in 874e3c95b9b9 Traceback (most recent call last): File "manage.py", line 20, in <module> execute_from_command_line(sys.argv) File "/usr/local/lib/python2.7/site-packages/django/core/management/__init__.py", line 353, in execute_from_command_line utility.execute() File "/usr/local/lib/python2.7/site-packages/django/core/management/__init__.py", line 302, in execute settings.INSTALLED_APPS File "/usr/local/lib/python2.7/site-packages/django/conf/__init__.py", line 55, in __getattr__ self._setup(name) File "/usr/local/lib/python2.7/site-packages/django/conf/__init__.py", line 43, in _setup self._wrapped = Settings(settings_module) File "/usr/local/lib/python2.7/site-packages/django/conf/__init__.py", line 99, in __init__ mod = importlib.import_module(self.SETTINGS_MODULE) File "/usr/local/lib/python2.7/importlib/__init__.py", line 37, in import_module __import__(name) ImportError: No module named {__SETTINGS__} ERROR: Service 'primatest_4' failed to build: The command '/bin/sh -c export COLLECTSTATIC=local && python manage.py collectstatic --settings=settings.{__SETTINGS__} --link --no-input' returned a non-zero code: 1 Since I have 0 domain knowledge of this problem I'm having a hard time diagnosing this error.

Django: SSL + trailing slash cause URL in browser to show unusual path
Hosting: A2Hosting Reference for A2Hosting deploy: link Python: 3.8.1 Django: 3.1.1 Webserver: Apache When "SECURE_SSL_REDIRECT = False" in settings.py, having the trailing slash in the urls.py paths causes no issue. urlpatterns = [ path('admin/', admin.site.urls), path('login/', dashboard, name="dashboard"), ] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT) In fact, accessing the URL http://subdomain.domain.com/login (or admin) the correct page is shown. But when I set "SECURE_SSL_REDIRECT = True", if I maintain the trailing slash and I access the same URLs, the page is still correctly shown, but the URL in the browser address bar changes. Instead to be: https://subdomain.domain.com/login it becomes: https://subdomain.domain.com/home/user/a2hosting_python_app/login/ For admin path, instead to be: https://subdomain.domain.com/admin/login/?next=/admin/ it becomes: https://subdomain.domain.com/home/user/a2hosting_python_app/admin/login/?next=/home/user/a2hosting_python_app/admin/ At this point, if I edit the urls.py removing the trailing slash: urlpatterns = [ path('admin', admin.site.urls), path('login', dashboard, name="dashboard"), ] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT) the login URL shows correctly, but the admin URL won't. I have no APPENDING_SLASH set in settings.py. Does anyone know why Django behave like this? What am I doing wrong? Many thanks in advance. -
Django Timezone filter returns wrong results
I wrote the following code: date = self.request.query_params.get('date') queryset = Fixture.objects.all().order_by('-date') if(date): date = pytz.utc.localize(datetime.strptime(date, "%Y-%m-%d")).astimezone(pytz.UTC) queryset = Fixture.objects.filter(date__date=date).order_by('date') Upon excuting this with date = "2020-09-02" the queryset returns values containing the date "2020-09-03". How come this happens and how can this be solved?
