Dictionary only adds in the last key value pair in for loop
I have a for loop that goes through a list of cities and assigns them each a total_city_value. I am trying to get each unique total_city_value created during the for loop added to the dictionary however it seems to be only keeping the final total_city_value in the for loop when I print the dictionary. for broad_variable in broad_variable_list: # check if the current broad variable is equal to the first broad variable the user chose if broad_variable == broad_variable1: # if the city's specific variable is equal to the specific variable the user chose get the value of it based on it's ranking weight if City.objects.values_list(broad_variable, flat=True).filter(city=cities).first() == specific_variable1: city_variable1_value = 1 * weight_variable1 #print("city_variable1_value",city_variable1_value) # else assign a value of 0 else: city_variable1_value = 0 # check if the current broad variable is equal to the second broad variable the user chose if broad_variable == broad_variable2: # if the city's specific variable is equal to the specific variable the user chose get the value of it based on it's ranking weight if City.objects.values_list(broad_variable, flat=True).filter(city=cities).first() == specific_variable2: city_variable2_value = 1 * weight_variable2 # else assign a value of 0 else: city_variable2_value = 0 total_city_value = city_variable1_value + city_variable2_value city_value_dictionary[cities] = … -
How to run Django tests in Docker using GitHub Actions
I am building my first full CI/CD pipeline for a Django/React.js project. It uses 2 workflows: build.yml and deploy.yml. The build.yml first builds the images then pushes them to the GH Packages. Then it pulls the images in a new job and runs tests (though I think this is wrong as I think jobs run in parallel - haven't got to this part yet).

Django - How to annotate a single Django object
So Django has this cool feature where you can annotate a query set as in you can add attributes to each object in a query set. For example if I have a query set of users I can annotate it with number of followers which is another table with a foreign key reference to user. This can be done with the QuerySet.annotate() function. I was wondering if this is possible for a single Django object. I have a view function that gets user info, which given a unique user UUID I return the users info in the user table as well as the number of followers and followees. 1 way to do this is just query across all follower and followee table for the uuid and create a dictionary that gets returned or annotate a single object. Is it possible to do this? views.py @api_view(['GET']) def get_user_info(request, user_uuid): is_current_user = user_uuid == str(request.user.uuid) # Return all user info including # of followers and followees models.py class User(AbstractDatesModel): uuid = models.UUIDField(primary_key=True) username = models.CharField(max_length=USERNAME_MAX_LEN, unique=True, validators=[ MinLengthValidator(USERNAME_MIN_LEN)]) created = models.DateTimeField('Created at', auto_now_add=True) updated_at = models.DateTimeField('Last updated at', auto_now=True, blank=True, null=True) class FollowUser(AbstractSimpleModel): follower = models.ForeignKey( User, on_delete=models.CASCADE, related_name='follower_id') followee = models.ForeignKey( … -
Accessing foreign key attributes for arithmetics in django rest framework
I'm trying to calculate the length of a house relative to some adjacent neighborhoods, such that, house_size / (neighborhood[0].length + neighborhood[1].length...): class House(models.Model): house_id = models.CharField(max_length=256, primary_key=True) size = models.IntegerField() neighborhood = models.ManyToManyField('neighborhood', through='HouseNeighborhoodLink') class Neighborhood(models.Model): length = models.IntegerField() I created a table to assign several neighborhoods with a house. Also, houses can be assigned to several adjacent neighborhoods: class HouseNeighborhoodLink(models.Model): house_id = models.ForeignKey(House, on_delete=models.DO_NOTHING) neighborhood = models.ForeignKey(Neighborhood, on_delete=models.DO_NOTHING) Serializers: class LengthFromNeighborhoodSerializer(serializers.ModelSerializer): class Meta: model = Neighborhood fields = ['length'] class HouseCoverageOfNeighborhood(serializers.ModelSerializer): Neighborhood = LengthFromNeighborhoodSerializer(read_only=True) class Meta: model = HouseNeighborhoodLink fields = ['house_id', 'Neighborhood'] I'm stuck in the three dots (...), where I want to access the length attribute of all neighborhoods and then calculate the proportion to a house. I'm not sure how to access the length of each neighborhood from HouseNeighborhoodLink table: class HouseCoverageDetail(generics.ListAPIView): queryset = HouseNeighborhoodLink.objects.all() serializer_class = HouseCoverageOfNeighborhood def get_queryset(self): house_id = self.kwargs['house_id'] neighborhood = self.queryset.filter(house_id=house_id) ... return result -

How do I reuse a ModelForm for a through model with an additional field?
I have a Model Example and corresponding ModelForm ExampleModelForm that I use in ModelFormset ExampleModelFormset = modelformset_factory(Example, form=ExampleModelForm) I have a many-to-many through Model with an additional property. class ExampleThrough(models.Model): batch = models.ForeignKey(Batch, on_delete=models.CASCADE) example = models.ForeignKey(Example, on_delete=models.CASCADE) property = models.FloatField() Is there a way to reuse the ExampleModelForm to create a ExampleThroughModelForm that I can also use in a ExampleThroughModelFormset? I want to have all of the same fields as the ExampleModelForm plus the one new property. I don't think I can inherit from the ExampleModelForm: class ExampleThroughModelForm(ExampleModelForm): class Meta: model = ExampleThrough fields = '__all__' because the documentation has this note: Normal Python name resolution rules apply. If you have multiple base classes that declare a Meta inner class, only the first one will be used. This means the child’s Meta, if it exists, otherwise the Meta of the first parent, etc. -
Desired Outcome: I want to dynamically create and render data from a One to Many Field to a template in Django
I have two models with One to Many relationship. The Models are Parent and Child respectively.

Django - Error when changing from GET to POST
I have a react/django application that works fine when the request is a GET request. For example, in the React part I have the following sendRequestParameters(url) { axios({ url: url, method: 'get', headers: { 'X-CSRFToken': 'csrf_token', 'Accept': 'application/json', 'Content-Type': 'application/json;charset=UTF-8', }, params:{ 'TECHNOLOGY': JSON.stringify(this.state.technologySelectedValue), // more parameters here, all in the same format }, paramsSerializer: function(params) { return qs.stringify(params, {arrayFormat: 'repeat'}) } }).then((response ) => { console.log(response.data); }).catch((error) => { console.log(error) }) } Then, in the backend, I get the parameters and return them (this function is called in another function where the returned parameters are used, that's why there is a return statement). def extractParameters(request): TECHNOLOGY = json.loads(request.GET.get('TECHNOLOGY')) # more parameters extracted here, same format return TECHNOLOGY etc. That all works fine. However, I need to change to POST requests, and when I make two small modifications to do this, I get an error. In the front end request with axios, I change the method: 'get' to method: 'post'. Then, in the backend, I change TECHNOLOGY = json.loads(request.GET.get('TECHNOLOGY')) to TECHNOLOGY = json.loads(request.POST.get('TECHNOLOGY')) This gives me the following error in the terminal TECHNOLOGY = json.loads(request.POST.get('TECHNOLOGY')) raise TypeError(f'the JSON object must be str, bytes or bytearray, ' TypeError: the JSON object … -

Getting the value of two rational variables inside a for loop and adding them outside the for loop
I have two for loops in my program. The first for loop goes through a list of cities and the second for loop goes through a list of broad variables (safety, affordability, transit, etc). Inside the second for loop I assign a value to each city's broad variable city_variable1_value = 1 * weight_variable1 and city_variable2_value = 1 * weight_variable2. Inside the first for loop I add both city variables to get a total value total_city_value = city_variable1_value + city_variable2_value however this value is consistently outputting as 0 instead of the desired outcome 0.57 Here are my print outputs for print("city_variable1_value",city_variable1_value) is 0.24 print("city_variable2_value",city_variable2_value) is 0.33 print("total_city_value",total_city_value) is 0 views.py def get_ranking(request): # if this is a POST request we need to process the form data if request.method == 'POST': # create a form instance and populate it with data from the request: form = RankingForm(request.POST) # check whether it's valid: if form.is_valid(): # process the data in form.cleaned_data as required specific_variable1 = form.cleaned_data['specific_variable1'] specific_variable2 = form.cleaned_data['specific_variable2'] broad_variable1 = form.cleaned_data['broad_variable1'] broad_variable2 = form.cleaned_data['broad_variable2'] # loop through each city in the database for cities in City.objects.values_list('city', flat=True): print("cities",cities) # loop through each broad variable in the list at the top of this … -
how to auto scroll down when new messages added
I am working with django , I want to scroll down auto when new messages added 'sent or received', I can scroll down auto when I refrech the page because of this code line : $("#card-body").animate({ scrollTop: 20000000 }, "slow"); but when I send and I receive new messages the messages go down until I can't see them I have to scroll down manually this is the js code : <script> /* send message*/ document.getElementById('send-btn-id').onclick = function (e) { const msg = document.getElementById('message').value; chatSocket.send(JSON.stringify({ 'message': msg, 'user': me, 'friend': friendName })); document.getElementById('message').value = ""; }; const friendName = JSON.parse(document.getElementById('friend').textContent); const me = JSON.parse(document.getElementById('me').textContent); /* set friend profile name */ document.getElementById('friend-name').innerHTML = friendName['username']; /* start conversation */ document.querySelector('.start-conversation').innerHTML = 'Start conversation with <strong>'+friendName['username']+'</strong>'; /* connection request */ const chatSocket = new WebSocket( 'ws://' + window.location.host + '/ws/chat/' + friendName['username'] + '/' ); chatSocket.onmessage = function (e) { const data = JSON.parse(e.data); var class_name = 'in'; var profile_image = '{{friend_obj.profile.image.url}}'; if(me['username'] == data.user['username']) { data.user['username'] = 'Me'; class_name = 'out'; profile_image = '{{request.user.profile.image.url}}'; } var chat_list = document.querySelector('#chat-list-id'); var chat = "<li class=\""+class_name+"\"><div class=\"chat-img\"><img alt=\"avatarchat\" src=\""+profile_image+"\"></div><div class=\"chat-body\"><div class=\"chat-message\"><h5>"+data.user['username']+"</h5><p>"+data.message+"</p></div></div></li>"; chat_list.innerHTML += chat; }; </script> -
Limit Django ModelForm ForeignKey choices depending on request.user
It is sometimes desirable to restrict the choices presented by the ForeignKey field of a ModelForm so that users don't see each others' content. However this can be tricky because models do not have access to request.user. Consider an app with two models: class Folder(models.Model): user = models.ForeignKey(get_user_model(), editable=False, on_delete=models.CASCADE) name = models.CharField(max_length=30) class Content(models.Model): folder = models.ForeignKey(Folder, on_delete=models.CASCADE) text = models.CharField(max_length=50) The idea is that users can create folders and content, but may only store content in folders that they themselves created. i.e.: Content.folder.user == request.user QUESTION: How can we use for example CreateView, so that when creating new content users are shown the choice of only their own folders? -
How to get item by hashed CharField in django
I have Device model that has a field named token that stores a pbkdf2_sha256 hashed string. from django.contrib.auth.hashers import make_password from django.models import Model, CharField class Device(Model): name = CharField(max_length=200) token = CharField(unique=True, max_length=128) def save(self,*args,**kwargs): self.token = make_password(self.token) super().save(*args,**kwargs) for example I have a Device object that it's token is hashed value of ABCD. now question is if I get ABCD from user as raw token, how i can find it's device from database? I tried this: I hashed the ABCD that I got from user with make_password, but the new hashed value wasn't as same as the old one that was in db. also I know that I can get device id from user and then check if user's entered token is same with check_password method. but I want only get token from user not device id and token. -
Django runserver memory leak?
Seemingly out of nowhere, whenever I called the url for my Django model, be it with ListView or DetailView, it would hang, and while doing so the memory would spike and I had to kill runserver. I have now tracked this issue down to subprocess._try_wait(). The simple solution seems to be to raise ChildProcessError. But this is source code, and I've always been told not to mess with source. So how am I supposed to fix this? With a decorator? That still has to go in the source, doesn’t it? Please advise. Also, I note that there is a comment in the source code about a python bug in the method immediately preceding _try_wait(), which is _internal_poll(). See http://bugs.python.org/issue15756 . However, that bug was reported and fixed all the way back in 2012, and it was thought to be identical to 1731717, reported all the way back in 2007 and fixed in Python 3.2. This project is my first on Python 3.9.9, so I am hoping this bug has not been re-introduced. Django is 3.2.9, os is Ubuntu 20.04. Also, all these comments and bug reports talk about “SIGCLD is set to be ignored.” But if that’s the better way … -

What is the name of that HTTPS session recorder & playback tool that has an API? Alt. how would you automate an HTTPS website to do user functions?
I've successfully used the tool before. It has a local webpage UI that you goto in your browser that lists the https traffic that occured, and options to play it back. It also comes with a command line tool. I am thinking of a small word ending in "mt", but can't seem to get google to find it. If you can offer any other suggestions that would also be great. Also, would that be an acceptable way to automate an HTTPS session for a website? There's a website I have to automate for a job, and they provide no API to help do the things that users can do on the site, so I am automating from scratch. Thank you for any guidance. I am not allowed to use Selenium webdriver. The code will be hosted on a Django host and the frontend to the automation scripts will be a Django website. -
