Why is post request data not available in Django app?
I have send a post request from a flutter app using dio in the code below Map<String, String> getData() { return { "firstname": firstname.value, "lastname": lastname.value, "phonenumber": phoneNumber.value, "password": password.value, "accounttype": accounttype.value }; } void signup(context) async { Dio dio = Dio(); final response = await dio.post( 'http://192.168.0.101:8000/signup/', data: getData(), ); debugPrint(response.toString()); } and tried to print it in django from the code below from django.http import HttpResponse from django.views.decorators.csrf import csrf_exempt @csrf_exempt def signup(request): if request.method == 'POST': print(request.POST) return HttpResponse('Hello, world!') I get an empty dictionary when it is printed. -
Django - Replace manually-entered primary key with AutoField
The issue I have a model with fields like this: class MyObject(models.Model): id = models.CharField(max_length=200) title = models.CharField(max_length=200, blank=True) [more fields not relevant to issue] I think I made the wrong decision using a manually-entered CharField as my primary key, so I would like to switch to an AutoField as my primary key. Ideally the resulting schema would look like this: class MyObject(models.Model): id = AutoField(primary_key=True) url = models.CharField(max_length=200) # containing the same data id used to contain title = models.CharField(max_length=200, blank=True) [more fields not relevant to issue] However, I am struggling to perform this migration, so I am looking for solutions on how to migrate to the new schema. What I've tried When I make a migration that just renames id to url, any page I try to load gives an error. For example, the admin page gives an error like MyObject has no attribute 'id'. I tried to add an AutoField named autogen_id to the model, and make that the primary key. However, when using the makemigrations command, I got the message It is impossible to add a non-nullable field 'autogen_id' to myobject without specifying a default. This is because the database needs something to populate existing rows. … -
Expenses Tracker Django Web App: Issue with Extract all expenses, sort and aggregate total expenses by month to display as js with chart.js
I am building a expenses tracker web app with django and have issues with the logic to sort and aggregate total expenses by month. The values are derived from a web form where the user enters an expense details which includes its date. From the date field, i want to sort and sum up each months total expenses to output the results as js into bar charts with chart.js. Should i be using .annotate(month=ExtractMonth('date'))?

Django `ImageField.file.read()` raises `bytes` object has no attribute `read`
This is the model I'm using: from django import models class Image(models.Model): file = models.ImageField(upload_to='uploads/images/') Now, if I do image.file.read() I get AttributeError: 'bytes' object has no attribute 'read' >>> from images.models import Image >>> img = Image.objects.first() >>> img.file.read() Traceback (most recent call last): File "<console>", line 1, in <module> File "...\.venv\lib\site-packages\django\core\files\utils.py", line 42, in <lambda> read = property(lambda self: self.file.read) File "...\.venv\lib\site-packages\django\core\files\utils.py", line 42, in <lambda> read = property(lambda self: self.file.read) AttributeError: 'bytes' object has no attribute 'read' image.file.file returns a bytes object and not a File object.

Is it safe to keep using django web app on local server and how safe is my data if I do it that
This might seem like a stupid question, but is it okay to keep using a django based web app on localhost. The abstract is that I made a accounting web app that I would like to use for my daily business transactions, I don't want to deploy the web app on internet. Is it okay to keep using it on local server with sqlite3 or is there another method of achieving the same? -
Unique together and sending null with nested serializer cause constranit error
I'm having an issue with making both of those two work... Did I miss something? I'm sending Json to my post(creating comment): { "content":"message", "myuser":{ "username":"ztestz", "source":"test", "email":null} } Which answers to unique_together fields for this model: class MyUser(models.Model): username = CharField(max_length=50, null=True, blank=True) source = CharField(max_length=50, default='discord') email = EmailField(null=True, blank=True) class Meta: unique_together = (('username', 'source',),('email', 'source',)) My nested serializer contains given create: class CommentSerializer(serializers.HyperlinkedModelSerializer): myuser = MyUserSerializer() def create(self, validated_data): myuser_data = validated_data.pop('myuser') print(validated_data) # myuser = MyUser.objects.filter( # Q(name=validated_data['username'], source=validated_data['source']) | Q(name=validated_data['email'], source=validated_data['source'])) # print(myuser) myuser = MyUser.objects.get_or_create(**myuser_data) print(myuser) # myuser = MyUser.objects.get_or_create(myuser, defaults={'source': validated_data['source'], 'username': validated_data['username'], 'email': validated_data['email']}) comment = Comment.objects.create(user_related=myuser[0], **validated_data) return comment For unknown to me reason, get_or_create returns constraint invalidation, even through the item definitely exists: { "myuser": { "non_field_errors": [ "The fields username, source must make a unique set." ] } } Could anyone explain to me, what is happening in here? Is there some kind of requirement for nested serializers to work with unique_together, or get_or_create to contain certain data? The data in **validated_data contains all the fields that would be included in default... -

Whats the best way of accessing django database with python script?
I have a django project which is made for running a website. I want to have a python script that is going to read django database and insert new data. Whats the best way of doing that? I assume that if I would just regulary connect to the database (using sqlite library for example) it might cause some conflicts because django app and my script are accessing same database at the same time. -
how to combine 2 models to realize permissions system
I am designing pet project for communities news system. I have this models: User, Group, Post, Like. I want to allow each User to Like posts. In addition to this some Users can be managers of Groups (like manyToMany relation), so they will be able to edit Group information and create Posts from Group name. But one of this "group managers" will have role "shef", and will be able to add/remove managers from his group. "shef" can be added just in Django Admin. What is the best way to design User <-> Group relation? I thought about Group having manyToMany to User (managers) and foreignKey to "shef", will it be optimal solution? How should I design the project to follow best practices, or should I use 3rd party libraries like django-guardians in this situation? -

Add a field for manual input when a radio button is checked and update database with django
I want to update the database from frontend using a form in django. The model I created is (I include only the relevant part to be more clear): class Stoixeia_pelati(models.Model): tainies_name = models.CharField(max_length=20, blank=True, null=True) Because I want to make a radio button selection on the frontend, I made a forms.py file. But I want when someone clicks other to open a new field where someone can write a value: class Stoixeia_pelatiForm(ModelForm): CHOICES = [ ('Choice1', 'Choice1'), ('Choice2', 'Choice2'), ('other', 'other'), ] tainies_name = forms.ChoiceField(choices=CHOICES, widget=forms.RadioSelect) class Meta: model = Stoixeia_pelati fields = ['name', 'tainies_name', 'skarfistires_name', 'belones_name'] In html I render the form: <form class="form" method="POST"> {% csrf_token %} <div class="form__field"> <label for="formInput#text">{{field.label}}</label> {{form.tainies_name}} </div> <input type="submit"> <form> In my views I added: form = Stoixeia_pelatiForm(instance=pelatis) if request.method == 'POST': form = Stoixeia_pelatiForm(request.POST, instance=pelatis) if form.is_valid(): form.save() return redirect(reverse('pelatis_krini', args=[pelatis_slug])) context = { 'pelatis':pelatis, 'syntages':syntages, 'form':form, } The selection is being submited and it works fine. My problem is that I don't know how to make a new field appear when someone clicks "othr" and then submit the value to the database and update "tainies_name" to the manually inputted value. -

how to create REST API system in Django which use a load balancer and messaging bus queue
Design a distributed banking REST API system that consists of a load balancer and two banking servers. The load balancer should direct read-only API requests to one of the banking servers, while transactional API requests should be sent to a message bus queuing system, which will distribute them to both banking servers. For example, bank account balance queries should be sent to one of the banking servers by the load balancer, while account creation, credit, and debit transactions should be sent to both banking servers by the load balancer via the message bus system. Can you write a prototype of this program using REST API and a message bus system? If you were to use either Django or Flask, how would you approach this problem? Does creating 2 different Django projects mean having 2 servers? -
