Errno 5 Input/output error when closing console
I have a video converter which is converting audio and video files. Everything works but if I close my terminal from my server the audio file convert doesnt work anymore. I use PyTube for converting and moviepy for converting the mp4 from pytube into mp3. (I think the problem has something to do with moviepy bc. before I didnt have it.) This is my code for converting audio: if format == "3": yt = YouTube(videolink) downloads = MEDIA_ROOT + "/videos/" ys = yt.streams.filter(file_extension='mp4').first().download(downloads) base, ext = os.path.splitext(ys) basename = os.path.basename(base + uuid + '.mp3') videoclip = VideoFileClip(ys) audioclip = videoclip.audio audioclip.write_audiofile(base + uuid + ".mp3") audioclip.close() videoclip.close() maybe something with the os code is wrong. But I cant figure out why it works if I leave the console open. Im thankful for every help I get. -
REST Django - How to Modify a Serialized File Before it is Put Into Model
I am hoping that I can find a way to resize an uploaded image file before it is put into the database. I am new to Django with REST, so I am not sure how this would be done. It seems that whatever is serialized is just kind of automatically railroaded right into the model. Which I suppose is the point (it's certainly an easy thing to setup). To clarify, I already have a function tested and working that resizes the image for me. That can be modified as needed and is no problem for me. The issue really is about sort of "intercepting" the image, making my changes, and then putting it into the model. Could someone help me out with some ideas of tactics to get that done? Thanks. The Model: class Media(models.Model): objects = None username = models.ForeignKey(User, to_field='username', related_name="Upload_username", on_delete=models.DO_NOTHING) date = models.DateTimeField(auto_now_add=True) media = models.FileField(upload_to='albumMedia', null=True) file_type = models.CharField(max_length=12) MEDIA_TYPES = ( ('I', "Image"), ('V', "Video") ) media_type = models.CharField(max_length=1, choices=MEDIA_TYPES, default='I') user_access = models.CharField(max_length=1, choices=ACCESSIBILITY, default='P') class Meta: verbose_name = "MediaManager" The View with post method: class MediaView(APIView): queryset = Media.objects.all() parser_classes = (MultiPartParser, FormParser) permission_classes = [permissions.IsAuthenticated, ] serializer_class = MediaSerializer def post(self, … -

CSRF verification failed: is token not persisting between GET and POST? Django
I checked a lot of the older CSRF questions, but they seem to be from 5+ years ago and a lot of the solutions aren't applicable due to now being handled with render() or other built-in methods. So, here's my question: I'm rendering a form template from a class-based view. It loads fine when I hit the initial GET request, but when I try to submit, it throws a 403: CSRF verification failed error. I'm not sure why this is happening - I feel like I'm doing everything right. Could it have something to do with saved cookies that override the CSRF token getting changed every time render is called? Here's my code: class Intake(View): form_class = IntakeFormSimple template_name = "intake.html" def get(self, req: HttpRequest): form = self.form_class(None) return render(req, self.template_name, {"form": form}) def post(self, req: HttpRequest): form = self.form_class(req.POST) if form.is_valid(): return HttpResponse("submitted form!") return render(req, self.template_name, {"form": form}) and the form template (boilerplate removed for clarity): <body> <section class="section"> <div class="container"> <form action="" method="post" novalidate> {% csrf_token %} {{ form.non_field_errors }} {% for field in form %} <div class="field"> <label class="label" for="{{field.id_for_label}}" >{{field.label}}</label > <div class="control">{{field}}</div> {% if field.help_text %} <p class="help">{{field.help_text}}</p> {% endif %} <ul class="errorlist"> {% … -
Why we write this, form = StudentForm(request.POST) in django?
This is my views function, def studentcreate(request): reg = StudentForm() string = "Give Information" if request.method == "POST": reg = StudentForm(request.POST) string = "Not Currect Information" if reg.is_valid(): reg.save() return render('http://localhost:8000/accounts/login/') context = { 'form':reg, 'string': string, } return render(request, 'student.html', context) Here first we store form in reg variable then also we write reg = StudentForm(request.POST) why? acutally why we write this? -
AWS elastic beanstalk Linux 2 with Django application failed to deploy
I am in this strange situation where I could not deploy the same code base to elastic beanstalk Linux 2 server after first time. The first deployment(after intentionally crashed server or new environment) works with no error but if I deploy the same code base again, It would fail at python manage.py migrate command in my .config file. I tried to put all my eb container commands in .config into .platform/hooks as .sh scripts, the deployment works, but I would get 502 Bad Gateway error and unable to see my site. Any insight? -

DRF APIClient Delete data arrives in request.data, not request.query_params
I use DRF's APIClient to write automated tests. And while is was writing the first delete test, I found it very strange that the data passed through arrived in request.data, while if I use Axios or Postman, it always arrives in request.query_params. Any explanation as to why this is, and preferably a method to use APIClient.Delete while the data arrives in query_params would be great! My test: import pytest from rest_framework.test import APIClient @pytest.fixture() def client(): client = APIClient() client.force_authenticate() yield client class TestDelete: def test_delete(client): response = client.delete('/comment', data={'team': 0, 'id': 54}) And my views from rest_framework.views import APIView class Comments(APIView): def delete(self, request): print(request.query_params, request.data) >>> <QueryDict: {}> <QueryDict: {'team': ['0'], 'id': ['54']}> Looked into DRF's APIClient. Feeding towards params doesn't seem to help. The delete method doesn't seem to have direct arguments that could help as well. So I'm a bit stuck. -
I am not getting expected result when I am multiplying price with quantity

Is there a method to create a Django token for user objects with no last_login timestamp?
I have a Django app that contains advertisement recipients with no login timestamps (since they do not need to have an account anyways), is there a method to customize the Django default token generator to exclude the timestamp requirement? -
Strange behaviour when rendering X-Axis ticks
I'm rendering a chart with matplotlib through panda's df.plot() method, but somehow the tick labels on the X-Axis seem to be messed up. There seems to be a layer of numeric text above my "real" tick labels. I have no idea where this comes from. Strangely enough, this only happens in our production and staging environment, not in dev. Maybe it also has to do with gunicorn or django's dev server. Has somebody made this experience before? Here's the plot result: and this is the output when I clear the ticks with .set_xticks([], []): Here's a portion of my code, there's some abstraction but I think it should be understandable. self.data is a pandas dataframe. It outputs base64-encoded png data: class Line(ChartElement): def draw(self): self._plot = self.data.plot(kind='line', color=self.colors) self._rotation = 'vertical' self._horizontalalignment='center' # self._plot.set_xticks([], []) # ... class ChartElement(): # ... def base64(self): self.draw() figfile = BytesIO() if not self._plot: raise ValueError("Plot not generated.") if self._legend: self._plot.legend(self._legend, **self._legend_args) #plt.legend(self._legend, loc='upper center', bbox_to_anchor=(0.4, .05), ncol=5, fancybox=False, prop={'size': 6}) plt.setp(self._plot.get_xticklabels(), rotation=self._rotation, horizontalalignment=self._horizontalalignment, fontsize=8) self._plot.set_ylabel(self.y_title) self._plot.set_xlabel(self.x_title) #plt.figure() fig = self._plot.get_figure() fig.autofmt_xdate() if self.size and isinstance(self.size, list): fig.set_size_inches(inch(self.size[0]), inch(self.size[1])) fig.savefig(figfile, format='png', bbox_inches='tight') figfile.seek(0) figdata_png = base64.b64encode(figfile.getvalue()) plt.clf() plt.cla() plt.close('all') plt.close() return figdata_png.decode('utf8')
