SAML authentication for HUE revoking admin access AFTER first login
I'm trying to set up SAML authentication for HUE deployed with AWS EMR, using Azure SSO as the IdP. I can actually get the handshake to work and the users are logging in to HUE, matching network login details to the usernames that are prepopulated in the HUE backend database. We create the users in HUE first and part of that setup includes setting some users with "is_superuser" to TRUE. The only attribute I explicitly look for to get from the IdP to HUE is the username/network-credential The behaviour I'm trying to understand is that the first person to log into the HUE UI is getting authenticated via SAML and logging in, with the admin/superuser privileges intact. But anyone after that logging in who is set up as an admin is losing the flag to indicate an admin, i.e. logged in as a normal user. If I manually go in afterward and set the users to have admin access in HUE database and have the users log in again, the access will be granted to the admin permissions and the problem seems to disappear but I don't understand why every login after the first is removing these permissions? I tried … -

Django use values or values_list with non related models
I have this both models: class GeneCombination(models. gene = models.ForeignKey(Gene, db_column='gene', on_delete=models.DO_NOTHING, db_constraint=False) class Gene(models.Model): name = models.CharField(max_length=50, primary_key=True) type = models.CharField(max_length=25) I know it's not the best model schema, it has to be like that due to business rules. I'm getting the values from GeneCombination model and some fields from Gene model. Now, It could be that a gene is not present in Gene model, in that case that rows are being filtered when I use values of values_list methods, which is what I want to prevent. This query is returning 31 elements: GeneCombination.objects.select_related('gene') But this query is returning 27 elements (is filtering the 4 elements whose gene does not exist in Gene table): GeneCombination.objects.select_related('gene').values('gene__type') How could I get empty values in case that It doesn't exist and prevent the rows to be filtered? Thanks in advance and sorry about my English -

Reuse Django Rest Framework Generic view to get its QuerySet
I have a Generic View of Django Rest Framework with a lot of settings (sorting, filtering, searching, etc): class MyViewClass(generics.ListAPIView): def get_queryset(self): return ... # IMPORTANT: this uses self.request def get_serializer_class(self): return ... # IMPORTANT: this uses self.request permission_classes = [permissions.IsAuthenticated] pagination_class = StandardResultsSetPagination filter_backends = [CustomOrdering, filters.SearchFilter] search_fields = ['field1', 'field2'] ordering_fields = ['field1', 'field2', 'field3', 'field4'] Now I want to make a file download from a QuerySet which must be computed with the same filters, sorting and searching parameters. Is there a way to reuse the QuerySet computed by that view? I don't need that to be paginated (however I think I could solve that problem from the frontend, so It doesn't worry me). I've tried calling get_queryset method with an ugly trick but It's not applying searching and ordering: @login_required() def download_result_with_filters(request): class MockRequest: request: HttpRequest mock_request = MockRequest() mock_request.request = request queryset = MyView.get_queryset(mock_request) ...

django app how to get a string from a function before
I am building a django app in which the user has to write a sentence in a text box. This sentence gets then sent to the server and received by it. After that the user has to click on continue and gets on a another html page. Here the user has to record an audio of a word he sais. The word is then turned into a string and after that sent to the server. Now I would like the function in views.py to find out if the word the user said is in the sentence the user wrote before. But the sentence is only in the first function that receives the sentence after it is sent. I know I could first store the sentence but is there also another way? -

Django UpdateView using formset and bootstrap fails
I'm new to django and I'm trying to write an application that given an activity allows me to save the information of the partecipants (i.e. Person) and how long the partecipation was. I was able to setup a CreateView, with bootstrap and JavaScript to allow my formset to be dynamic and I'm able to register the activity and the partecipants though the create view. However, when I try to modify an already existing activity, using an UpdateView, I get several errors. I tried to reproduce a minimal example of my problem and I got the error "This field is required" that is one of the error I obtain in my main application. I'm trying also to reproduce the second error: the instruction formset.is_valid() in views.py return False since it has an Activity already linked to the Person (violating the unique_together rule). This happens everytime: even if I'm just trying to add a second person to the form without changing anything about the first one. Please, let me know if I missed some files: here's the small example. models.py from django.db import models # Create your models here. class Person(models.Model): surname = models.CharField(max_length=30) class Activity(models.Model): name = models.CharField(max_length=30) person = models.ManyToManyField(Person, … -
Select a valid choice Django Filtered Drop Down Menu
Devs, In my project I have a form that has a field that has a student name selection, it is a drop down field by the students that are currently enrolled in that particular class. It gets this information from table Section Enrollment than checks the master Student table. The filtering works out correctly, however when I submit my form, it says the student name is not a valid choice. My guess is because its submitting that student name and not a ID, I'm not 100% sure. Here is my models and view. I don't know how to fix this. Appreciate that help. QUERY IN QUESTION: getstudents = SectionEnrollment.objects.filter(section_id=classid).select_related().values_list('studentpsid_id__student_name', flat = True) MODELS: # Creation of Classrooms and Assigned Teachers class SectionEnrollment(models.Model): sectionenrollmentpsid = models.CharField(primary_key = True,max_length = 50, default = "") section = models.ForeignKey(Section,on_delete = models.PROTECT, default = "" ,) studentpsid = models.ForeignKey(Student,on_delete = models.PROTECT, default = "" ,) entry_date = models.DateField(blank=True) exit_date = models.DateField(blank=True) dropped = models.BooleanField(default = False, blank = True) class Meta: verbose_name = "Student Section Enrollment" def __str__(self): return self.sectionenrollmentpsid # Where Basic Student Data Is Stored class Student(models.Model): studentpsid= models.CharField(primary_key = True , default = "", max_length = 50, unique = True) student_name = … -

DRF Serialize only selected keys of JSONField
I want to serialize specified key:value pair of JSONField in DRF but not the whole JSON. What I got from their website: Starting from Django Rest Framework 3.12, the JSONField of Django is supported. Nested search with JSONField started to be supported with double underscore notation as used in Django itself. You can read the exact statement from https://www.django-rest-framework.org/community/3.12-announcement/#support-for-jsonfield But I didn't find anything related to my problem. When I use double underscore notation for serialization (ex. details__link), I get error saying model doesn't contain that field. -
Django Register Page refill input data after site reload
Im looking for a solution to refill my select fields of a Register Page after a site reload, if the user has given invalid data and should correct the problem. The use of the Django Template works fine on the input field. There I can just give the value of the tag a django variable and when the variable is filled it gets displayed. But on the birthdate selections i have to use an if statement for every option that sets the select attribute selected="selected". And this for 31 days, 12 months and around 90 years. So there are 133 if statements and I think this is slowing down the backend unecesserily. I try to avoid java script and I have some safety concerns about window.sessionStorage so I would rather use my way with Django Templates. Do you know a more elegant solution for refilling a select field? the function: ``` def registerPage(request): context = {} #needed for the value rebuild when user has to reload the register page if request.method == 'POST': first_name = request.POST.get('fname') last_name = request.POST.get('lname') password1 = request.POST.get('password1') password2 = request.POST.get('password2') email = request.POST.get('user_email') birth_day = request.POST.get('bday') birth_month = request.POST.get('bmonth') birth_year = request.POST.get('byear') gender_type = request.POST.get('gender_type') …
