Creating a service layer with Django Rest Framework
I am fairly new to web-development and just studing design patterns and code architecture. Now, I am developing service layer for business logic. And here I have a dillema. One approach is to use command design pattern. Where I have a class which implements user creation and related processes (e.g. sending email, writting logs etc), also this class has one public method (entry point) and private methods, called inside the entry point. Here is the example of what I mean. class CreateUser: def _create_user(self, **data) -> User: # here perform creation of user itself, requesting repository layer ... def _send_email(self, **data) -> None: # here I send email def _write_logs(self, **data) -> None: # writing logs to a file def execute(**data): self._create_user(**data) self._send_email(**data) self._write_logs(**data) On the other hand, there is a approach where I create a common service as a class, that handles user authentication and registration and for each user action has one method: class UserService: def create_user(self, **data) -> User: # call to repository # send email # write logs def update_user(self, **data) -> User: # call to repository # write logs I don't really know what solution I should choose. I suppose that the command pattern is … -

Display contents of the database table selected by user in Django
As per user selection I want to display course details. I do not want to create multiple pages for each course detail. So, at course-detail.html I am passing a course-code as hidden value in html form which is table name in my database project. When a user submits the query for course, I pass the course-code value by POST method into my views.py file. But there I am not able to use post method string as a model name. courses.html {% for courses in english_courses %} <form action="{% url "course-detail" %}" method="POST"> {% csrf_token %} <input type="hidden" name="course-code" value="{{courses.course_code}}"> <button class="btn-lg btn-primary d-inline-flex align-items-center" type="submit" onclick="document.location.href='{% url "course-detail" %}';"> {{course.name}} </button> &nbsp; {% endfor %}</form> views.py def course_detail(request): if request.method == "POST": course_request = request.POST['course-code'] course_request = course_request.capitalize() course_details = course_request.objects.all() return render(request, 'course-detail.html', {'course': course_details}) else: messages.warning(request, "Link seems to be broken. Please contact admin.") return render(request, 'course-detail.html') this throws an error: AttributeError at /english/course-detail 'str' object has no attribute 'objects' -

How to check if a Django CharField is empty
I've been working on a Django database project and I need to return a value only if a CharField is not empty. class author(models.Model): name = models.CharField(max_length=255, unique=True, help_text='Article author') pronouns = models.CharField(max_length=255, help_text='Enter pronouns (optional)', blank=True, verbose_name='Pronouns (optional)') if pronouns != '': def __str__(self): return f'{self.name} ({self.pronouns})' else: def __str__(self): return self.name Despite me not entering anything in the pronouns field when testing, it still acts as if it has a value and returns Name () with nothing in those parentheses. I have tried, checking if it is None or '' and setting default='' and then checking if it is not equal to the default. None of those have worked. How do I fix this? -
DRF serializer validation of inputs across multiple nested fields
I'm using DRF serializers for models with measurements with units. Here's my model: class Cargo(models.Model): length = models.FloatField() height = models.FloatField() weight = models.FloatField() input_length_unit = models.IntegerField(choices=LengthUnits.choices) input_weight_unit = models.IntegerField(choices=WeightUnits.choices) I have the following serializers to convert data like {"length": {"value": 10, "unit": 1}, ...} to my model schema: class FloatWithUnitSerializer(serializers.Serializer): value = serializers.FloatField() unit = serializers.IntegerField() def __init__(self, unit_type, field_name, *args, **kwargs): super().__init__(*args, **kwargs) self.unit_type = unit_type self.field_name = field_name def to_representation(self, instance): value = getattr(instance, self.field_name) unit = getattr(instance, f"input_{self.unit_type}_unit") # convert from database unit to input unit value = value * UNITS[self.unit_type][unit] return {"value": value, "unit": unit} def to_internal_value(self, data): # convert from input unit to database unit value = data["value"] / UNITS[self.unit_type][data["unit"]] return {self.field_name: value, f"input_{self.unit_type}_unit": data["unit"]} class CargoSerializer(serializers.ModelSerializer): length = FloatWithUnitSerializer("length", "length", required=False, source="*") height = FloatWithUnitSerializer("length", "height", required=False, source="*") weight = FloatWithUnitSerializer("weight", "weight", required=False, source="*") class Meta: model = models.Cargo fields = ["length", "height", "weight", "input_length_unit", "input_weight_unit"] This works, but now I want to prevent unit-mixing. For example given the unit type "length", which includes the "length" and "height" fields (units are meters, feet, etc), they need to post the same unit for both, e.g. {"length": {"value": 10, "unit": 1}, "height": {"value:15", "unit": 1}}. … -
django-otp and dj-stripe conflict
i'm searching a way to implement django-otp and dj-stripe in a web project but i think there is a conflict because django-otp uses custom admin_site.register() to register models while dj-stripe uses admin.site.register(). i'm triyng with the following code but not works because all stripe model are registered not following list_display field customizations as in admin.py on github repository. #urls.py from django.contrib import admin from django.urls import path, include from account.admin import admin_site urlpatterns = [ path("realadmin/", admin_site.urls), path("stripe/", include("djstripe.urls", namespace="djstripe")), ] #admin.py from django_otp.admin import OTPAdminSite from django_otp.plugins.otp_totp.models import TOTPDevice from django_otp.plugins.otp_totp.admin import TOTPDeviceAdmin # Stripe modules from djstripe import models class OTPAdmin(OTPAdminSite): pass admin_site = OTPAdmin(name='OTPAdmin') # Script to register all models modelsarray = django.apps.apps.get_models() # Register other django-otp models with the custom admin site (admin_site) for model in modelsarray: try: if model.__module__.startswith("dj-stripe"): # Register with the default admin.site for dj-stripe models admin.site.register(model) elif model == Customer: admin_site.register(model, CustomerAdmin) else: # Register with the custom admin site for other models (e.g., django-otp) admin_site.register(model) except admin.sites.AlreadyRegistered: pass so, i want to register stripe's models using admin.site.register because in this way i can use admin.py code of github repository but i need also to use admin_site.register for otp secutiry tool. can … -
How to get value from select2 in Django
I am trying to add a new constraint, but according to the data, the code takes all values except acc_id4 and c_center, and the result is always something like Row 1: acc_id4=None, description=salary 10/2023, doc=1023, d_date=2023-11-25, debit=1000, credit=0.00, c_center=None I don't know why it's always nothing Is the problem in the template or in the Django code? And how do I solve this problem? Note: The JavaScript code creates a new row and makes the old row read-only. It also copies the values except for the acc_id4 and c_center values. It also makes the generated name add a number after the _ sign. html {%load static%} <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Acc Entry</title> <link rel="shortcut icon" href="{% static 'image/daleel.ico'%}" > <link rel="stylesheet" href="{% static 'css\Entry.css'%}"> <!-- Font Awesome --> <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/5.15.4/css/all.min.css" integrity="sha512-1ycn6IcaQQ40/MKBW2W4Rhis/DbILU74C1vSrLJxCq57o941Ym01SwNsOMqvEBFlcgUa6xLiPY/NS5R+E6ztJQ==" crossorigin="anonymous" referrerpolicy="no-referrer" /> <link rel="stylesheet" href="{% static 'plugins/fontawesome-free/css/all.css'%}"> <link rel="stylesheet" href="https://fonts.googleapis.com/css2?family=Open+Sans:wght@300;400;600&display=swap" > <link rel="stylesheet" href="https://fonts.googleapis.com/icon?family=Material+Icons"> <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.0.2/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-EVSTQN3/azprG1Anm3QDgpJLIm9Nao0Yz1ztcQTwFspd3yD65VohhpuuCOmLASjC" crossorigin="anonymous"> <link href="https://cdn.jsdelivr.net/npm/select2@4.1.0-rc.0/dist/css/select2.min.css" rel="stylesheet" /> </head> <body> <div class="radio"> <div class="btn-group" role="group" aria-label="Basic radio toggle button group"> <input type="radio" class="btn-check" name="btnradio" id="btnradio1" autocomplete="off" > <label class="btn btn-outline-primary" for="btnradio1">New</label> <input type="radio" class="btn-check" name="btnradio" id="btnradio2" value="save" autocomplete="off"> <label class="btn btn-outline-primary" for="btnradio2">Save</label> <input type="radio" class="btn-check" … -

Django Forms widget tweaks allow only alphatbet letters in text field
I am trying to restrict input in text fields to only alpha letters also via client side I have tried this, but this doesn't work. the script: <script type="text/javascript"> function Validate(e) { var keyCode = e.keyCode || e.which; var regex = /^[A-Za-z]+$/; var isValid = regex.test(String.fromCharCode(keyCode)); return isValid; } </script> Then the call: {% render_field form_built_properties.building_material|attr:"onkeypress(Validate)" class="form-control" %} I tried this alone, doesn't work either: {% render_field form_built_properties.building_material|attr:'onkeydown="return /[a-z]/i.test(event.key)"' Ideally there should be a function that on clicking the submit button checks that building_material text field (and others) have been correctly filled before submitting all data. -

Mismatch between column type in MySQL and Django model value
I have a model class defined as follows: class Person(models.Model): # ... spending = models.BigIntegerField(blank=True, null=True) # ... And populate it like so: p = Person( # ... spending = str(row['spending']) # ... ) p.save() In which row is a pandas DataFrame row. What will the type of the field be in the database? What if the field is defined as TextField and what I insert is int(row['spending')? Looking at the type in MySQL I can guess the defined field type is enforced. Will it still be the case if the column contains null values? For example, the field is of type numeric and we insert null values will it remain numeric or it will change to Text to accomodate the nulls? -

Slow Loading and 500 Errors with Django Project on Apache Server
Hello Stack Overflow community, I'm encountering performance issues with my Django project hosted on an Apache server. When accessing the site through Apache, it either takes a very long time to load or returns a 500 error.

Celery Emails and Accessing Mailbox
I'm in the process of moving my emails over to Celery tasks to run asychronously. Porting over my existing tests I'm struggling with an AssertionError when I attempt to access the mail.outbox. I assume this is due to the mailbox being created within the Celery thread rather than within the scope of the test. Is there any way around this to test the email has succesfully sent? I've pretty much ran out of ideas on the best way to approach this.
