Django - What is wrong with my view function?
In this function, the script can't get past the second if statement. def save_data(request): if request.method == 'POST': if request.POST.get('id')\ and request.POST.get('id1')\ and request.POST.get('id2'): try: print('if2') data=Flow() data.id = request.POST.get('id') data.id1 = request.POST.get('id1') data.id2 = request.POST.get('id2') data.save() except Exception as e: print(e) My question is pretty simple, why might this be happening? If you'd like to see more code please let me know in the comments. -
Login with limited IP addresses
I have written a custom authentication that allows only certain IP addresses to login. Below is my code: def get_client_ip(request): x_forwarded_for = request.META.get('HTTP_X_FORWARDED_FOR') if x_forwarded_for: ip = x_forwarded_for.split(',')[0] else: ip = request.META.get('REMOTE_ADDR') return ip def authenticate(self, request, username=None, password=None): # do something I am trying to write a test for it. Although, seems like my solution has an empty request. Here's my code: def test_login(self): # create user .... .... # pass a custom HTTP_X_FORWARDED_FOR client = Client(HTTP_X_FORWARDED_FOR='127.0.0.1') response = client.login(username='username', password='password') assert response.status_code == 200 This throws an error AttributeError: 'NoneType' object has no attribute 'META' So, perhaps my request in the fuction somehows is None. How can I fix this ? Thanks in advance! -
Data from one table not writing to another table
I have User table which contains registered user. I have created Enter table which has to record info about when user went through turnstile by using rfid tag. Model has been created, code been written but it doesn't work and not writing data to table. Last row in Written code file should write data to database, but now it doesn't. Thanks in advance! models.py from django.db import models class Department(models.Model): class Meta: verbose_name_plural = 'Отделы' department_name = models.CharField(verbose_name='Отдел', max_length=40, editable=True, unique=True) def __str__(self) -> str: return self.department_name class User(models.Model): class Meta: verbose_name_plural = 'Участники' first_name = models.CharField(verbose_name='Имя', max_length=40) last_name = models.CharField(verbose_name='Фамилия', max_length=40) rfid_mark = models.CharField(verbose_name='RFID', max_length=8, editable=True, unique=True) department = models.ForeignKey(Department, on_delete=models.CASCADE) datetime = models.DateTimeField(auto_now=True, editable=False) def __str__(self) -> str: return self.first_name + ' ' + self.last_name class Enter(models.Model): class Meta: verbose_name_plural = 'Проход' user = models.ForeignKey(User, verbose_name='Пользователь', on_delete=models.CASCADE) datetime = models.DateTimeField(auto_now=True, verbose_name='Время', editable=False, null=True, blank=True) enter_status = models.BooleanField(editable=False, verbose_name='Статус входа') turnstile_id = models.CharField(verbose_name='id Терминала', max_length=50) def __str__(self) -> str: return self.user + ' ' + self.enter_status Written code class Actions: def gives_access_if_registered(self): connection = database.connects_to_database() cur = connection.cursor() while True: ser.write(request_for_read) scanned_rfid = ser.readline().hex()[12:20] cur.execute("SELECT * FROM passage_user WHERE rfid_mark=?", (scanned_rfid,)) all_database_rows = cur.fetchall() for data in all_database_rows: name … -
threaded websocket in django and kubernetes
I have a model for which I take some data from another website using a websocket and send a request to another website and save the result to database. what I'm doing right now is in my appconfig's ready I create the websockets for all my model's instances in database and store them in a global dictionary where i can access the thread for each model instance using it's PK. I have two questions: As my website gets bigger, with each model having its own thread would that cause me a problem having more than 10,000 threads for example? If I want to scale the application using kubernetes for example would I get into a problem? Because with each instance of my application, threads will spawn and they all try to do the same thing while I only want it to be done once. Also the code doesn't look so pretty this way so I assume there must be other ways of doing this in django which would also be scalable, so I appreciate any suggestion. -
Dual behavior for Class Based View
Let's say that we model university programs, which are divided in tracks. A track belongs to a program. So: class Program(models.Model): name = models.CharField(max_length=30) class Track(models.Model): name = models.CharField(max_length=30) program = models.ForeignKey(Program, on_delete=models.CASCADE, related_name='tracks') I'd like to allow the creation of a track, with the possibility of specifying the program it belongs to, so I can use: class TrackCreateView(CreateView): model = Track fields = ['name', 'program'] But from the program details, I want to allow the creation of a track for that specific program, so I came up with: class ProgramTrackCreateView(CreateView): model = Track fields = ['name'] def form_valid(self, form): form.instance.program_id = self.kwargs['pk'] return super().form_valid(form) In the urls.py, a pk parameter is provided, so this will populate the program_id correctly. Is there any way to merge these two views into a single one, e.g. passing a parameter to the .to_view() method, or something similar? Because I need to change the list of fields to be displayed before the form is created and I need to know if I need to override program_id or not. -
Django : pass session information to next template & view
I'm trying to build a little website where users can set up tournaments and then invite players for their tournaments. These are my Tournament and Invite models: class Tournament(models.Model): tourney_name = models.CharField(max_length=200, null=False, blank=False) event = models.ForeignKey(NewsArticle, on_delete=models.DO_NOTHING, related_name='tourneys') host_user = models.ForeignKey(get_user_model(), on_delete=models.CASCADE) # player_count_limit = models.PositiveIntegerField(validators=[MaxValueValidator(100)]) player_join_deadline = models.DateField() fantasy_team_size = models.PositiveIntegerField(validators=[MinValueValidator(5),MaxValueValidator(15)]) created_dt = models.DateTimeField(auto_now_add=True) last_modified_dt = models.DateTimeField(auto_now=True) def __str__(self): return self.tourney_name def get_absolute_url(self): return reverse('home') class Invite(models.Model): name = models.CharField(max_length=200, blank=True, null=True) email = models.CharField(max_length=320, null=False, blank=False, validators=[EmailValidator],) invited_by = models.ForeignKey(get_user_model(), on_delete=models.DO_NOTHING) invited_for = models.ForeignKey(Tournament, on_delete=models.DO_NOTHING) created_dt = models.DateTimeField(auto_now_add=True) def __str__(self): return self.email def get_absolute_url(self): return reverse('home') And then these are my Views: class MakeTourneyView(CreateView): template_name = 'make_tourney.html' model = Tournament form_class = MakeTourneyForm def form_valid(self, form): form.instance.host_user = self.request.user form.save() return super(MakeTourneyView, self).form_valid(form) def get_success_url(self): return reverse('invite_players') #return reverse('invite_players', kwargs={'tourney_id': self.object.id}) def update_session(self): tourneyobj = self.get_object() self.request.session['tourney_id'] = tourneyobj.id return self.request.session['tourney_id'] class InvitePlayersView(CreateView): template_name = 'invite_players.html' model = Invite form_class = InvitePlayerForm def form_valid(self, form): tourney_id = self.request.session['tourney_id'] form.instance.invited_for = Tournament.objects.filter(id=tourney_id).get() form.instance.invited_by = self.request.user form.save() return super(InvitePlayersView, self).form_valid(form) I'm doing something wrong because the tourney_id is not being set on form.instance.invited_for ; instead when I click submit I get Django error saying "KeyError at /tourney/inviteplayers/ 'tourney_id'" Any … -
Django ContentType for relation to many models
I am working on model which is suppose to have relation to many different models, but one instance should have relation to only one of those models. Like Model Response which should store response body parsed on fields but this response can be from different sites which have different set of fields. Searching through SO i find that using django GenericRelation is good approach, so I tried it as below: class Response(models.Model): content_type = models.ForeignKey(ContentType, on_delete=models.CASCADE) object_id = models.PositiveIntegerField() service_data = GenericForeignKey("content_type", "object_id") class ServiceOne(models.Model): field1 = models.CharField(...) class ServiceTwo(models.Model): field2 = models.CharField(...) With those models I want to do something like this: s1 = ServiceOne.objects.create(field1="Foo") s2 = ServiceTwo.objects.create(field1="Bar") r1 = Response.objects.create(service_data=s1) r2 = Response.objects.create(service_data=s2) but it is throwing django.db.utils.IntegrityError: null value in column "content_type_id" violates not-null constraint. Solutions like "Add null=True" (as here Django Make ContentType Not Required) are not what I expect since I want this relation to be, not to get rid of error itself. According to https://docs.djangoproject.com/en/3.2/ref/contrib/contenttypes/ it should work just fine but I assume I miss something. I tried adding this to ServiceOne and ServiceTwo response = GenericRelation( Response, content_type_field='content_type_fk', object_id_field='object_primary_key', ) and model_type = ContentType.objects.get( app_label='actual_app_label', model="serviceone" ) s1 = ServiceOne.objects.create(field1="Foo") r1 = Response.objects.create( … -

django-plotly-dash how to integrate 3 different dash files
Earlier was using dash server with a base.py which runs dash app server to run the files which was combined using dashboard.py which renders data from files A and B which has data and responsive UI. Now trying to move it to django using django-plotly-dash. Could someone help one this. File Structure: base.py - dash app server dashboard.py - from base imports app, from a imports a_tab (which contains a dataframe) from b imports b_tab (which contains a dataframe) runs server both a.py and b.py --- from base imports app Have setup everything with django-plotly-dash but the data is not populating by clicking UI. -
Python - overlap time period business hours [closed]
I try to find the best way to solve this problem: I'am coding a scheduler for machine job. I will have a postgres table with all day of a year. Every row has different columns with start and ends of shift work. For example: day 17/01/21 - start_time_work1 00:00 - end_time_work1 20:00 - start_time_close1 20:00 - end_time_close1 00:00 day 18/01/21 - start_time_work1 00:00 - end_time_work1 04:00 - start_time_close1 04:00 - end_time_close1 06:00 - start_time_work2 06:00 - end_time_work2 12:00 - start_time_close2 12:00 - end_time_clos22 00:00 There may usually be several shifts on the same day. The purpose is to create a function that allows me, by entering a work start date and a work duration, to know, considering only the work periods, when this work will end. For my example: 17/01/21 18/01/21 Work Closed Work Closed Work Closed |----------------------------|----------|----------|---------|----------|---------------| 00:00 20:00 00:00 04:00 06:00 12:00 00:00 Input: |--------------------------------| 01:00 (22hous) 23:00 Output |-------------------------------------------| 01:00 (26hous) 03:00 Input: |---------------------------------------| 01:00 (24hous) 01:00 Output |-------------------------------------------------------------| 01:00 (30hous) 07:00 -

How to make complex searches in django ? Use views or models?

FileNotFoundError with matplotlib and apscheduler
My goal is to download data from a website, plot a graph, save it, and display it on a webpage. I am using Django 3.2, Python 3.9.5, pandas and matplotlib. When I just had the below code in my views, everything worked and the graph displayed correctly: r = requests.get(url_lab) #url_lab defined elsewhere, not relevant z = zipfile.ZipFile(io.BytesIO(r.content)) if file_lab in z.namelist(): #file_lab defined elsewhere, not relevant df_lab = pd.read_csv(z.open(file_lab), dtype={'a': str, 'b': str, 'c': float}, usecols=col_list, parse_dates=['Period'], \ encoding = "ISO-8859-1", engine='python') df_lab.set_index('Period', inplace=True, drop=True) df_lab = df_lab.sort_index().loc['2015-03-03':] x = df_lab.index[df_lab.Series_reference == "HLFQ.S1A1S"] y = df_lab.Data_value[df_lab.Series_reference == "HLFQ.S1A1S"] fig = plt.plot(x, y) plt.savefig('static/images/lab-empl-lev.png') However, I don't want this code to run every time I run the server, and in fact it's important that the data gets updated at a specific time every day. So I need to use some kind of task scheduler, and decided on apscheduler. So, following a tutorial, I made a new folder, containing an empty __init__.py, fetch.py with the previous code in it and updater.py: fetch.py: def get_lab_data(): r = requests.get(url_lab) z = zipfile.ZipFile(io.BytesIO(r.content)) if file_lab in z.namelist(): df_lab = pd.read_csv(z.open(file_lab), dtype={'a': str, 'b': str, 'c': float}, usecols=col_list, parse_dates=['Period'], \ encoding = "ISO-8859-1", engine='python') df_lab.set_index('Period', … -

I am looking for the session key that should be the same from the time when the user logs in until he logs out. I am communicating with another api that requires such key. I tried using csrf token but this one is different per request. Also, I have tried using session storage and again it is different one. I see that in the django_sessions there is a session_key that is created during the login, but I dont know how to assosiate it with a user, it has only session_key, session_data and the expire date. def user_login(request): if request.method == 'POST': response = None form = LoginForm() username = request.POST.get("username") password = request.POST.get("password") cookie = request.COOKIES['csrftoken'] user = authenticate(username=username, password=password) # logger.info(f"Session key [Login] --> {request.session}") # logger.info(f"Session key [Login] --> {request.session.session_key}") # request.session.create() # logger.info(f"Session key [Login] --> {request.session.session_key}") if user is not None: logger.info(f"Cookie [Login] --> {cookie}") response = loginApi( username, password, 'demo', cookie) if response["status"] == 200: login(request, user) logger.info("User logged in") return redirect('home') else: logger.info(f"Request Response [Log in] --> {response}") else: logger.error(f"User failed [Log in] --> {response.text}") else: form = LoginForm() return render(request, 'users/login.html', {'form': form}) -
How can I properly send images (and text) from React to Django API using fetch?
My django API views is setup as follows; class AddProductToStorageAPIView(APIView): parser_classes = [MultiPartParser, FormParser] def post(self, request, format=None): print(request.data) #I want to know what data is coming in for now return Response({"details": "all done successfully"}, status=200) When I make a POST request from postman (with formdata), the data request.data returns: <QueryDict: {'title': ['Something'], 'description': ['some description'], 'price': ['600'], 'category': ['A'], 'Images': [<InMemoryUploadedFile: img-transparent_bg.jpg (image/jpeg)>]}> However, when I try to make a POST request from the react side. Things got so messed up. First here is my code in react side: const handleSubmit = (e) =>{ e.preventDefault(); var headers = new Headers(); headers.append("Content-Type", "multipart/form-data"); headers.append("X-CSRFToken", csrftoken) var formdata = new FormData(); formdata.append("title", state.title); formdata.append("description", state.description); formdata.append("price", state.price); formdata.append("category", state.category); for (var i = fileinput.current.files.length - 1; i >= 0; i--) { formdata.append("Images", fileinput.current.files[0], fileinput.current.files[0].name); }//because the file input has 'multiple'='true' (i.e multiple files can be added) var requestOptions = { method: 'POST', headers: headers, body: formdata, redirect: 'follow' }; fetch("http://127.0.0.1:8000/api/v1/plus/product/", requestOptions) .then(response => response.text()) .then(result => console.log(result)) .catch(error => console.log('error', error)); } On submit however, I get 400 bad request error saying multipart form parse error - invalid boundary in multipart:None and I don't have a clue what that means. Then, … -
