Python Django ConnectionAbortedError [WinError 10053]
So im facing a weird issue while making a request to my api. It works fine using something like postman. I get my response no issue but if I make a request from my frontend(on a seperate domain) the connection gets closed for some reason. Here is my code I make ajax request using axios axios.get(mydomain/api/oauth) .then(response => { console.log(response) }).catch(error => { console.log(error.response.data) }) which hits my backend method that should return a response like so def oauth(request): auth_client = AuthClient( settings.CLIENT_ID, settings.CLIENT_SECRET, settings.REDIRECT_URI, settings.ENVIRONMENT ) url = auth_client.get_authorization_url([Scopes.ACCOUNTING]) request.session['state'] = auth_client.state_token return HttpResponse(url) But at this point I get this alarm ConnectionAbortedError: [WinError 10053] An established connection was aborted by the software in your host machine And like I said if I make this same request through postman I get my response. So I don't know what I am missing. I have applied cors thinking maybe its because my frontend is on seperate domain from backend but no luck. Plus the alarm is kind of vague... anybody face similar issue? -
Ajax in Django To Populate Form Field
I am trying to learn to use ajax and could use some help. I want to click a button and have that populate a django form field, Exporter. Here is what I have. I know my script is not sufficient, but I am novice and would hope to use this as a functioning example for myself. So upon click of button #populate, the Exporter form field should populate with 'Me'. Thanks! views.py def Ajax(request): if request.is_ajax(): exporter = 'Me' data = json.dumps(exporter) return HttpResponse(data, content_type='application/json') proforma.html <button id="populate"> Populate </button> ... <table class="table2" width=100%> <tr class="bigrow"> <td rowspan = 2 >Exporter: {{form.Exporter}}</td> <td colspan = 2 >Pages:</td> </tr> </table> ... $("#populate").click(function() { $.ajax({ url: "/ajax/more", success: function(data) { $("#exporter").load(); } } }); }); </script> forms.py class ProformaForm(forms.ModelForm): class Meta: model = Proforma fields = [ 'Name', 'Shipment', 'Exporter'] widgets={ 'Exporter': forms.TextInput(attrs={'id': 'exporter'}), } -
How to make forms dynamic in Django
This question is more theoretical than practical. So, this is a Django project about tracking workouts. I have several models in this project. 1) Workout. It contains fields user and date. 2) Exercise. It contains fields workout (which connects to the model above), name, sets, repetitions, and weight. My idea is as follows: You have an HTML table for each of the workouts, which contains each exercise in a new row. You can add and delete exercises "on the fly" by adding or deleting rows and the data inside <td> tags is editable in the table itself. My question is: 1) How to implement the models (or forms) into an HTML table and make the data editable. 2) How to save models automatically. Kind of like auto-save in Google Docs or something like that. This includes the addition or deletion of exercises and the information about them. I understand that this is a lot to ask, so replies about any part of the project are welcome. I also suspect that a REST API will be needed for this. I have not explored what that is in-depth and how that might help me solve my problem. So, if that is the … -
Displaying ModelAdmin fields in the same line issue
I delved in Django Documentation(https://docs.djangoproject.com/en/3.0/ref/contrib/admin/) and I found out I can display fields name in the same line by wrapping with tuple. So this is how I did: class MovieAdmin(admin.ModelAdmin): fields = (('title','length'),'release_year') admin.site.register(Movie, MovieAdmin) But my admin site shows only removed horizontal line between fields names, not displaying two names in the same line. Here's my screenshot: enter image description here Using Django 3.0.3, Python 3.8. Thanks. -

I am not able to access my admin in Django
I have Ubuntu VM with Apache Server on which i am running my application. I have inserted some login and registration file using Filezilla. But my registration, Login and admin page is not working. It is giving me Exception Type: OperationalError Exception Value: attempt to write a readonly database I tried the following after doing some Stackoveflow. chown root db.sqlite3. Unfortunately, I still get the same error when trying to access above page. Any help would be greatly appreciated! Probably something to do with changing user permission which i have no idea where to start in diagnosing what permission issue is going on. -

storing files in models.py from views.py
I am trying to fill a Django model field with a pdf that is altered by the user's input in views.py.

Creating and editing objects with different features Django
I'm new to web developing with Django. I'm creating a website where I have multiple objects with different features: Character: Name, description, morality, strength. Item: Name, description, owner. Adventure: Name, description, characters, places, duration. Some of this features are the same for the objects (like name and description) but some aren't. Users will be able to create and edit each one of these objects. I would like to not have to program code to create and edit each one individually and just have to do it once for an object that can be any of these and that will only have the features corresponding to that object, but I don't know how. I tried making an object with a type which would be "Character" or "Item" depending on what it was and then picking the features using an if Object.name == "Character" but that didn't work. What should I do? Another problem that I have is that for my Adventures I can only choose one character and I would like to be able to choose an undefined amount of characters. Since I'm still learning I'm not sure how to do that exactly. -

Django Many to One relationship form

Cannot run migrate by using a existing database
I am using Django3 and Python3 with the latest version to learn Django. I want to use an existing sqlite3 database for my django project. But I have problems while I was using the migrate command. I have done very few steps to my project so far: 1. use the venv, upgrade pip, install django, 2. generate a project, 3. insert an app, and add it into INSTALLED_APPS, 4. In the settings.py, I added the existing database into the DATABASES as follows. DATABASES = { 'default': { 'ENGINE': 'django.db.backends.sqlite3', 'NAME': os.path.join(BASE_DIR, 'db.sqlite3'), }, 'testdb': { 'ENGINE': 'django.db.backends.sqlite3', 'NAME': os.path.join(BASE_DIR, 'TestDB.sqlite3'), }, } Then I use the method as here shows, to generate the models.py file.

Django OnetoOne Field not Populating
I have a model which is named 'client. It's defined in models in part as the following: class Client(models.Model): username = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) I've run makemigrations and migrations, but when I create a new client object and try to save it from forms I get and Integrity Error: NOT NULL constraint failed: intake_client.username_id. username_id is the field name Django automatically generates with the migration, but saving these forms results in this field containing a null value and is not being generated automatically as a dependency by Django. If I set primary key to true in the username, it works ok, but then I have problems deleting the objects because Django says the model does not have an "id" field (since it is now changed to username_id). Why is Django not generating and putting the dependency values in the username_id field automatically when the instance is saved? -

Django HTML iterate trough a dynamic dictionary name
I'm trying to create a website where part of the website I'm using dynamic tabs in html where each tab will show different data. Now what I'm trying to do is that in the views.py I'm creating different dictionaries for the different tabs. So far I have created the below in the views.py file. def display_rpt (request): alltrasfData={} sec = Section.objects.all() for key in sec: transactions = Transaction.objects.values('feast_year__title','feast_year','feast_group__title','section','section__short').filter(section_id=key.id).order_by('section','-feast_year','-feast_group__title').annotate(Total_income=Sum('income_amt'),Total_Expenditure=Sum('expenditure_amt')) subtotal = Transaction.objects.values('section','feast_year','feast_year__title').filter(section_id=key.id).annotate(Total_income=Sum('income_amt'),Total_Expenditure=Sum('expenditure_amt')) grandtotal = Transaction.objects.values('section').filter(section_id=key.id).annotate(Total_income=Sum('income_amt'),Total_Expenditure=Sum('expenditure_amt')) alltrasfData[f'transactions_{key.id}']=transactions alltrasfData[f'subtotal_{key.id}']=subtotal alltrasfData[f'grandtotal_{key.id}'] = grandtotal alltrasfData['sec']=sec return render(request, 'homepage/reports.html',alltrasfData) Just to give you an idea some dictionaries that there are in the alltrasfData are: 'transactions_1','transactions_2','transactions_3' Is there a way in Django html where I can iterate trough these different dictionaries with dynamic dictionary name. -
