Error - POST /dsahboard/api/investigator HTTP/1.1 400 160 - Django REST API error
I am trying to incorporate DataTables Editor into a Django REST API. While I am able to get the datatable to display, the create button will not work and returns "POST /dashboard/api/investigator/ HTTP/1.1" 400 160 I've setup the editor according to the documentation but the API still won't seem to accept it. The 400 status code indicates it is a bad request, but what does the 160 mean? Can anyone provide input if I setup the datatable wrong? urls.py from django.urls import path, include from . import views from rest_framework import routers from .views import StudyList, StudyDetail, InvestigatorView app_name = 'dashboard' router = routers.DefaultRouter() router.register('study', views.StudyView) router.register('investigator', views.InvestigatorView) router.register('lead', views.LeadView) router.register('institution', views.InstitutionView) router.register('site', views.SiteView) investigator_list = InvestigatorView.as_view({ 'get': 'list', 'post': 'create' }) investigator_detail = InvestigatorView.as_view({ 'get': 'retrieve', 'PUT': 'update', 'patch': 'partial_update', 'delete': 'destroy' }) urlpatterns = [ path('', views.datatables, name='datatable'), path('investigator/', views.datatables_investigator, name='datatables_investigator'), path('api/', include(router.urls)), path('api/investigator/', investigator_list, name='InvestigatorList'), path('api/investigator/<int:pk>', investigator_detail, name='InvestigatorDetail'), path('api/study/', StudyList.as_view(), name='StudyList'), path('api/study/<int:pk>/', StudyDetail.as_view(), name='StudyDetail') ] datatables_investigator.html {% extends 'base_datatables_editor.html' %} {% block content %} <h1 style="text-align: center; padding-top: 1em; padding-bottom: 1em;">Investigators</h1> <div class="row"> <div class="col-sm-12"> <table id="InvestigatorDataTable" class="table table-striped table-bordered" style="width:100%"> <thead> <tr> <th scope="col">First Name</th> <th scope="col">Last Name</th> <th scope="col">Name</th> <th scope="col">Email</th> <th scope="col">Institution</th> </tr> </thead> … -
integrity-error django :violates not-null constraint
I build a social media application where all actions are concluded in the same count. However with the like button i get an error even if the code looks exactly the same as the dislike version. The error is: IntegrityError at /like-post null value in column "num_interactions_total" of relation "core_likepost" violates not-null constraint DETAIL: Failing row contains (98, a4aaa95b-a3a5-49a6-8f63-de768bfa0786, 2023-02-02 18:01:13.121023+00, , 1, null, 7). but the num_interactions_total count is already deleted and does not exist in the model or views.py anymore. I've also deleted the migrations. I'm using the postgresql database. I´m a little confused, why it gives me an error only with this button and not with all the others... How do I avoid the null error?

Django "AND" query: Reverse ForeignKey or ManyToMany giving an unexpected result
I found a different result on an "AND" query depending if it was a reverse of forward query. In a FORWARD query you can do this: Model.objects.filter(x=1) & Model.objects.filter(y=2) Model.objects.filter(x=1, y=2) Model.objects.filter(Q(x=1) & Q(y=2)) All give the same result: a QuerySet that satisfies both conditions (x=1 and y=2). But If I have a REVERSE FOREIGNKEY or MANY TO MANY “AND” query something different happens. This is what I did and expect. I have these models: class Blog(models.Model): name = models.CharField(max_length=100) tagline = models.TextField() class Author(models.Model): name = models.CharField(max_length=100) country = models.ForeignKey(Country, on_delete=models.CASCADE) class Entry(models.Model): blog = models.ForeignKey(Blog, on_delete=models.CASCADE) headline = models.CharField(max_length=255) body_text = models.TextField() pub_date = models.DateField() authors = models.ManyToManyField(Author) And let's say I have this data: Headline Pub Date Year Authors Blog Pop 1 2023 Juan Pop Pop 2 2023 Emma Pop Pop 3 2010 Juan, Walmer Pop Other 2023 John Beatles I want to make an “AND” query to get the authors that satisfy both the headline that contains the word “Pop” and Pub Date Year equal to 2023. Expected result: Juan and Emma. Headline Pub Date Year Authors Blog Pop 1 2023 Juan Pop Pop 2 2023 Emma Pop We can use the following methods: Multiple Arguments … -

Accessing Continuous Data from Websockets in Django Channels
Improved Question: In the file "apisGo.py", I have two methods that retrieve data from servers through websockets. This data is updated continuously, meaning the function never ends. The issue is that I need to receive the contents of the "msg" variable from both "apiA" and "apiB" in my "WSConsumer" class, so I can send it to the frontend. What is the correct way to do this? file apisGo.py async def apiA(): async with websockets.connect('wss://ws-api...)) as ws: msg = {"id": "%s" % (uuid), "type": "", "topic": "", "response": True} msg = json.dumps(msg) await ws.send(msg) while True: msg = await ws.recv() async def apiB(): async with websockets.connect('wss://ws-api...)) as ws: msg = {"id": "%s" % (uuid), "type": "", "topic": "", "response": True} msg = json.dumps(msg) await ws.send(msg) while True: msg = await ws.recv() async def main(): task1 = asyncio.create_task(apiA()) task2 = asyncio.create_task(apiB()) await asyncio.gather(task1, task2) if __name__ == "__main__": asyncio.run(main()) file "consumers.py": import apisGo class WSConsumer(WebsocketConsumer): def connect(self): self.accept() asyncio.run(apisGo.main()) I considered using global variables in the "apisGo.py" file and using the "import multiprocessing" in "consumers.py" to create two routines: one to initiate the requests "asyncio.run(apisGo.main())" and another to access the global variables.

Django ORM dublicate objects in queryset after order_by by foreignkey field
I have encountered some unexpected sorting behaviour with objects. As soon as I sort by the related model field, I get duplicates. A short description of the model fields models.py class GoogleCreativeSpend(models.Model): creative = models.ForeignKey( 'GoogleCreative', on_delete=models.CASCADE, ) spend = models.DecimalField() class GoogleCreative(CreamCreative): ..... Create some objects: >>> creative = GoogleCreative.objects.get(name='gs_video1031v1') >>> spend = GoogleCreativeSpend(creative=creative, spend=100,) >>> spend.save() >>> spend = GoogleCreativeSpend(creative=creative, spend=1100,) >>> spend.save() >>> spend = GoogleCreativeSpend(creative=creative, spend=1,) >>> spend.save() views.py queryset = GoogleCreative.objects.all() queryset.order_by('googlecreativespend__spend') for i in queryset: if i.name == 'gs_video1031v1': print(i.name) | gs_video1031v1 | gs_video1031v1 | gs_video1031v1 I.e. by creating 3 googlespend objects I get 3 duplicates for googlecreative after sorting. According to How to sort queryset based on foreign key with no duplicates I tryied queryset.distinct() and queryset.distinct('googlecreativespend__spend') But it doesn't work How to fix it ? -

Django field should not be shown in form but added by middleware at POST request
Let's say I've the following model: from django.db import models class MyModel(models.Model): foo = models.CharField() bar = models.CharField() The field "foo" should not be shown in the create form. Therefore the form is: from django.forms import ModelForm class MyForm(ModelForm): fields = ('bar',) The field is NOT shown in the form. Excellent! Now when POSTing the form, a middleware adds the 'foo' field to the POST vars. But when saving I get an "NOT NULL constraint failed: foo" error. There seems to be some magic code aligning the POST vars (with "foo") to the form fields (w/o "foo"). I already played with the "editable=False" setting, but no success, same behaviour. Any idea how to resolve this? -

How can I add the currently logged in username to the access log of django.server?
I'm trying to add the currently logged in username, if any, to the access log of a Django app: INFO [django.server:161] "GET / HTTP/1.1" 200 116181 ^ username should go here My main problem is how do I share the user/username between the middleware and the filter, since in the filter I don't have access to the request object?

Django: matching query does not exist. Error: 500
I'm trying to find a bug - already a second day. The goal was to create a button to save in-session a piece of information about a particular page that would be "read later". I'm trying to find out why I can't find a match in my query. The id that should be generated in POST is 8, but from what I understand from logs, it's 0. I'm looking for suggestions on how to find out where the problem is. I exchausted all ideas that I had. Additionally, I wonder if is it a good or bad idea that in my views.py I defined called model EssayCls in two functions where I define it with different names. In def get as selected_essay = EssayCls.objects.get(slug=slug), but in def post as post = EssayCls.objects.get(slug=slug). My views.py: class MyEssaysView(View): def is_stored_essay(self, request, post_id): stored_essays = request.session.get("stored_essays") if stored_essays is not None: is_saved_for_later = post_id in stored_essays else: is_saved_for_later = False return is_saved_for_later def get(self, request, slug): # print("GET: slug:", slug) # test user_agent = get_user_agent(request) selected_essay = EssayCls.objects.get(slug=slug) user_feedback = UserFeedback() context = { 'essay_found': True, 'essay_all': selected_essay, 'post_tags': selected_essay.tags.all(), 'form': user_feedback, 'comment_form': CommentForm(), 'comments': selected_essay.comments.all().order_by("-id"), 'saved_for_later': self.is_stored_essay(request, selected_essay.id) } if request.method == … -
Reusing a database record created by means of Celery task
There is a task which creates database record {R) when it runs for the first time. When task is started second time it should read database record, perform some calculations and call external API. First and second start happens in a loop In case of single start of the task there are no problems, but in the case of loops (at each loop's iteration the new task is created and starts at certain time) there is a problem. In the task queue (for it we use a flower) we have crashed task on every second iteration. If we add, at the and of the loop time.sleep(1) sometimes the tasks work properly, but sometimes - not. How to avoid this problem? We afraid that task for different combination of two users started at the same time also will be crashed. Is there some problem with running tasks in Celery simultaneously? Or something we should consider, tasks are for scheduled payments so they have to work rock solid -
How do I apply higher permissions to child pages in Wagtail?
I am building an intranet site for my organization with Wagtail and we are in the process of adding a knowledge base. The entire site needs to be restricted to logged-in users, but certain pages need to only be accessible to users in certain groups. For instance, only members of the IT group should be able to access the pages underneath the IT Knowledge Base page. Currently if I set the top-level page to be accessible only by logged-in users, that permission is applied to every page on the site, and I am barred from setting more specific permissions on any child page. It is imperative that I be able to set more specific permissions on child pages. I was able to find Wagtail Bug #4277 which seems to indicate that the logic for more specific permissions is implemented but not exposed in the admin UI. I am not familiar with the inner workings of Wagtail yet, especially how Wagtail permissions intersect with Django permissions. How can I add more specific permissions to child pages? -
