Problem of Q() for and two condition in Django models
Suppose that I have these models: class X(models.Model): interface = models.OneToOneField('Interface', related_name='x') class Y(models.Model): interface = models.OneToOneField('Interface', related_name='y') class Interface(models.Model): CHOICE = ( (0, 'this is x'), (1, 'this is y'), ) owner_type = models.IntegerField(choices=CHOICE,) Now, I want to get count Interface Objects that dosen't have x relation and y relation. I used these two way: z = Interface.objects.filter(x__isnull=True).filter(y__isnull=True).count() # Get correct number of objects x = Interface.objects.filter(Q(x__isnull=True)and Q(y__isnull=True)).count() # Get wrong number of objects The z return correct result but x return wrong number. Why this happend? -

How to 'convert' MP3 file to numpy array or list
I'm working on an audio-related project that connects with Django backend via rest api. Part of the front-end requires to display waveforms of associated mp3 files and for this, it in turn requires optimized data of each mp3 file in form of an array, which the front-end (javascript) then processes and converts to a waveform. I can pick the associated mp3 file from backend storage, the problem is converting it into an array which I can serve to the front-end api. I have tried several methods but none seem to be working. I tried this How to read a MP3 audio file into a numpy array / save a numpy array to MP3? which leaves my computer hanging until I forced it to restart by holding the power button down. I have a working ffmpeg and so, I have also tried this Trying to convert an mp3 file to a Numpy Array, and ffmpeg just hangs which continues to raise TypeError on np.fromstring(data[data.find("data")+4:], np.int16). I can't actually say what the problem is and I really hope someone can help. Thank you in advance! -

Django - Use TextInput form to look up a ForeignKey
I'm currently trying to build an application in Django where users should be able to create new entries for a model. Said model contains a ForeignKey relation to a different model. However, the classic dropdown form field is not practical, because there could be hundreds of entries to choose from. Instead, I'd like to allow users to simply type in the name of the entry (all names are unique), which then gets transformed to the corresponding ID when pressing the Submit button. I feel like this should be pretty straightforward to do, but since I'm new to Django I'm having a hard time to figure out how to do it. Currently the problem is, that the form field is declared invalid, due to the ForeignKey not existing (since the user typed in the name and not the ID of the database entry). Code example: forms.py: class DogForm(ModelForm): class Meta: model = Dog fields = "__all__" widgets = {" shelter": widgets.TextInput(attrs={"id":" shelter", "placeholder":" Dog Shelter"}), "name": widgets.TextInput({"id":"name", "placeholder":"Name"}), def clean(self): shelter= self.data.get("shelter") self.cleaned_data["shelter"] = Shelter.objects.get(name=shelter) return self.cleaned_data views.py: class DogCreate(CreateView): model = Dog form_class = DogForm def form_valid(self, form): if form.is_valid(): instance = form.save(commit=False) instance.save() return super(DogCreate, self).form_valid(form) As you can … -

Application Error in Heroku while deploying Django app, specifically, the log tail says = Build failed -- check your build output: *link*
This is my very first time deploying a Django app in heroku and I was following an article to git push and all the other tasks. The problem started when I started to push master. My app was not loading. So from heroku documentation I moved the push to main and deleted the master. And a new problem arose that is the application error, and asked to heroku log --tails. Later I found the Procfile didn't had the right app name. corrected that and restarted heroku. Still it shows application error with the line in red saying : Build failed -- check your build output: https://dashboard.heroku.com/apps/6609d304-92ca-454e-8659-561a8adbb11a/activity/builds/6c1dd096-0d90-49af-a5db-55eec4dff27b for the heroku logs --tail. terminal : heroku logs --tail (env) D:\DJPROJ\OFFSET_V1.1\v1>heroku logs --tail 2021-05-30T08:27:39.043493+00:00 app[api]: Initial release by user aera4242@gmail.com 2021-05-30T08:27:39.043493+00:00 app[api]: Release v1 created by user aera4242@gmail.com 2021-05-30T08:27:39.615588+00:00 app[api]: Enable Logplex by user aera4242@gmail.com 2021-05-30T08:27:39.615588+00:00 app[api]: Release v2 created by user aera4242@gmail.com 2021-05-30T08:33:03.000000+00:00 app[api]: Build started by user aera4242@gmail.com 2021-05-30T08:33:32.000000+00:00 app[api]: Build failed -- check your build output: https://dashboard.heroku.com/apps/6609d304-92ca-454e-8659-561a8adbb11a/activity/builds/bb5f0314-a49e-4e29-b6a0-1ec421b92733 2021-05-30T08:47:08.146897+00:00 app[api]: Starting process with command `python manage.py migrate` by user aera4242@gmail.com 2021-05-30T08:47:08.852782+00:00 heroku[run.2613]: State changed from starting to up 2021-05-30T08:47:09.202077+00:00 heroku[run.2613]: Awaiting client 2021-05-30T08:47:09.491181+00:00 heroku[run.2613]: Starting process with command `python manage.py migrate` … -

Django REST social login with dj_rest_auth does not authenticate the user
I am building an application. The client is built with Next.js and the backend with Django and Django REST framework. In this application, I would like to have social login. So far, my situation is this. I have set up the OAuth on the Google dashboard On the client, I am using next-auth - The client is successfully calling Google and getting an access token from there. On the client, the callback that runs after getting the access token from Google makes a call my Django API. I have set up the backend with dj_rest_auth - My settings are almost identical to the ones described here. Once the client callback runs and calls my Django API with the access token from Google, I successfully get on the client an access token and a refresh token. If it is a new user loggin in the first time, a new user is created in Djangos DB const response = await fetch(`${djangoAPIurl}/api/social/login/google/`, { method: 'POST', headers: { 'Content-Type': 'application/json' }, body: JSON.stringify({ access_token: accessToken, id_token: idToken }) }); const data = await response.json(); const { access_token, refresh_token } = data; Both access_token and refresh_token are defined and appear to be valid tokens.

Chart js space above bar graph
I generate graph depending on the value from my calculations. Problem is, I don't know how to set up 'margins', how to define where to put data labels. Datalables definition: datalabels: { anchor: 'end', align: 'start', offset: 5, Problem is, when a certain month value is 0, it's written over the labels on the bottom. Easy way to fix this would be to define a space about each column, so that it can that text can never go 'off screen' and define align: 'end'. Case 2: -
Module does not define class error while replacing default admin site
I'm following a tutorial for the Django admin app and I'm trying a step in which the default admin site is replaced with a custom subclass of AdminSite from django.contrib.admin. My project structure is: MyAdminTutorial |- MyAdminTutorial |- MyActualApp |- JustAUserApp MyActualApp.admin.py: class MyAdminSite(admin.AdminSite): pass admin.site = MyAdminSite() admin.site.register(User, UserAdmin) admin.site.register(Group, GroupAdmin) MyActualApp.apps.py: from django.contrib.admin.apps import AdminConfig class MyAdminConfig(AdminConfig): default_site = 'MyActualApp.admin.MyAdminSite' MyAdminTutorial.settings.py INSTALLED_APPS = [ "MyActualApp.apps.MyAdminConfig", # 'django.contrib.admin', .... "JustAUserApp", ] If I try to run the development server I get this error: ImportError: Module "MyActualApp.admin" does not define a "MyAdminSite" attribute/class Messing around in the debugger i found the error stems from a call to getattr() inside import_string() in django.utils.module_loading.py. For the current call to import_string() the module name and path are set to MyActualApp.admin, getting the current location in the debug console yields the main MyActualApp directory (the project's), but calling getattr(module, "MyAdminSite") triggers the error above. I expect the MyAdminSite class to be found, but that's not the case, what is going on in this project, what further checks am I not considering?
