Celery TaskResult inserted after finishing task
I have some strange behavior with the Celery task queue-module in the Django Framework in Python. My code works when all variables are correctly set up. But implementing some validation code that is separate from Celery seems to interfere with Celery. I'll explain what I am programming first. My complete code is at the bottom of this post. Dashboard users can execute tasks which are sent through Redis to a Celery-worker. This works. Next to that I also successfully implemented the Celery Progress-backend, and with it's ProgressRecorder I can now set the progress. Some jQuery, Ajax, html and css enable a fancy progress bar in the dashboard. I now combined this ProgressRecorder together with some custom code in a class. This works as well. With the custom code you can specify which Python function definitions should log progress. My code is built modular so function definitions are re-used on many levels and not every function should log in every task. Therefore the developer should specify which functions should log progress. The user does this with the 'display_progress_of_defs'-key when initiating the class: progress_recorder = ProgressRecorder(self) progress_logging = LogTaskProgressV3(task_id=task_id, app_id=app_id, progress_recorder=progress_recorder, total_steps=total_steps, display_progress_of_defs=["function_def_a", "function_def_c"]) In the class I added validation to confirm … -
Doctor appointment booking system in Django
I am trying to create doctor appointment booking system in Django. I have two models: Doctor and Patient, with personal details. I am looking for the way how to connect both, using specific time-slots/date for appointments. Doctors may be available in a different time-slots or days. For example: Doctor A is available from Monday to Friday, 8:00 - 16:00. I need to book Patient A for 30-minutes appointment at 10:00 and Patient B at 10:30. class Doctor(models.Model): first_name = models.CharField(max_length=30, verbose_name="First name") second_name = models.CharField(max_length=30, verbose_name="Second name") doctor_type = models.ForeignKey(Specialisation, on_delete=models.CASCADE, verbose_name='Specialisation') doctor_status = models.CharField(max_length=30, choices=status_choices, default='Non-Active', verbose_name='Doctor status') image = models.ImageField(upload_to='photos', blank=True, verbose_name='Photo') def __str__(self): return self.second_name + " " + self.first_name class Patient(models.Model): first_name = models.CharField(max_length=30, verbose_name="First name") second_name = models.CharField(max_length=30, verbose_name="Second name") contact_details = models.CharField(max_length=30, verbose_name="Contact details") postcode = models.CharField(max_length=3, verbose_name="PostCode") patient_status = models.CharField(max_length=30, choices=status_choices, verbose_name='Patient status') def __str__(self): return self.second_name + " " + self.first_name Thanks! -
How does React and Django actually work together
Hello I have now just started with learning React however I am getting a bit confused how does this two i.e Django and React actually get to work with one another. With routing from page to page is this handled by Django or React or this is a choice that one can take self? I am also wondering when dealing with normal Django templates same applies when using react or what? I have been searching where I can get a full blog/write-up where I can learn how to integrate the two and the best practices to this two but could not seem to find the one that is answering me or I just did not understand because I am a Beginner in this domain. Will this be best practice(This is the idea that I had on how people use this two frameworks) the idea that I had is one just builds a backend api that which then React can use however the rest such as page routing is all handled by React is this true or best practise or the is a better way in which people handle this. Can you please give me a detailed explanation on how this … -

djongo as second db engine
I want to add mongodb as second database on my django project. I use djongo lib.

Why aren't changes to my css visible in HTML page (django)?
I have a weird Problem with my django project. I have added a static folder in my app called home. Within the static folder I made another folder called home. The full path for my .css files is: C:/Users/myuser/app/home/static/home/new.css I have successfully loaded this .css file and the styles I added are visible when viewing the HTML page. However I made some alterations to that new.css file and saved it. However the HTML page only displays the css from the original .css file. Is this normal? Can anyone think of a reason this might be happening? Thanks in advance :) -
AttributeError from Django model inheriting an abstract base model
I'm trying to put together a simple little app that allows users to keep track of their own pokemon. Each pokemon has 1-2 different 'types' (e.g. fire, water, etc.), so I've added in a clean function to limit the maximum number of types the user can select. However, when trying to add a pokemon I am given the following error: AttributeError at /admin/pokollector/custompokemon/add/ 'CustomPokemon' object has no attribute 'poke_types' I'm assuming this has something to do with the poke_types variable not being properly inherited, but I have no idea why that would be. Here is the code from my models.py file: from django.db import models from django.core.validators import MinValueValidator as min, MaxValueValidator as max from django.core.exceptions import ValidationError class PokeType(models.Model): poke_type = models.CharField(max_length=15) def __str__(self): return self.poke_type #Current generation of games for gen_added field gen = 8 class Pokemon(models.Model): poke_name = models.CharField(max_length=30) poke_type = models.ManyToManyField(PokeType) evolves_from = False evolves_into = False gen_added = models.PositiveIntegerField(validators=[min(1), max(gen)]) def clean(self): #Allow max of 2 poke_types to be selected if len(self.poke_types > 2): raise ValidationError('A Pokemon has a maximum of two types.') class Meta: verbose_name_plural = 'Pokemon' abstract = True class CustomPokemon(Pokemon): name = models.CharField(max_length=30) level = models.PositiveIntegerField(blank=True, null=True) def __str__(self): return self.name -
Can I use Signal receiver within a class
I have a signal like this: virtual_daily_created = django.dispatch.Signal(providing_args=['min_date', 'max_date', 'train_id']) Calling it from a view like this: signal = virtual_daily_created.send_robust(self.__class__, min_date=start_ts, max_date=end_ts, train_id=train_id) and the receiver is in a class defined like this: class BigQueryData: def __init__(self): some_code def set_query(self, table: bigquery.TableReference, train_id: str, min_date: datetime, max_date: datetime,**kwargs) -> str: do_thing def set_table(self, type: str) -> bigquery.TableReference: do_thing @receiver(virtual_daily_created) def get_gga_data(self, min_date: datetime, max_date: datetime, train_id: str, **kwargs): do_thing Finally in my app containing the BigQueryData class, in a app.py file I have: from django.apps import AppConfig from django.dispatch import receiver class ShiftsConfig(AppConfig): name = 'shifts' def ready(self): from api.v1.virtual_daily_report import VirtualDailyReportList from reports.signals import virtual_daily_created virtual_daily_created.connect(receiver, sender=VirtualDailyReportList) Thing is when a signal is received I got this error: get_gga_data() missing 1 required positional argument: 'self' So I tried to change my signal like this: virtual_daily_created = django.dispatch.Signal(providing_args=['self', 'min_date', 'max_date', 'train_id']) And to Call it like this: signal = virtual_daily_created.send_robust(self.__class__, self=BigQueryData(), min_date=start_ts, max_date=end_ts, train_id=train_id) But then when I receive a signal I get this error: send_robust() got multiple values for argument 'self' Is it even possible to receive a signal from a method with self as first arg ?

How do I render DJango-Rest-Framework apis to templates like in Native Django
I have successfully made the apis using Django Rest's views and serializer. Due to some issues I now want to render templates and run the project using native Django. Now how do I migrate the modelviewsets and serializer to render templates and work like native Django does. Although apis are working I want full custom template rendering. This is how my API looks like= [ { "id": 6, "created_at": "2020-07-17T10:11:34.154037Z", "updated_at": "2020-07-27T14:36:44.319520Z", "cartitem": [ { "id": 17, "item": { "id": 11, "price": "500.00", "quantity": 22, "size": 1, "color": 2 }, "quantity": 5 } ], "number_of_items": 5, "total": "2500.00" } ] This is my cart API for the e-commerce website I am working on. Note that I have written viewsets and serializer, everything is correctly working, I want to render this. I cant find enough resources how to. -
Celery on Heroku doesn't shutdown properly when I automatically deploy from github

Here I want to have two basePaths, /api/v1/public/ for public_schema_view and /api/v1/private/ for private_schema_view So, the question is, how can I set multiple custom basePath in drf-yasg ? -
ImportError on python setup.py develop
This is my directory structure: api-models - api_models - __init__.py - models.py - migrations - __init__.py - 0001_initial.py - setup.py This is my setup.py: from setuptools import find_packages, setup setup( name='api_models', version='0.1.1', packages=['api_models'], ) In my project, this is in my settings.py: INSTALLED_APPS = ( 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'debug_toolbar', 'waffle', 'simple_history', 'rest_framework', 'rest_framework.authtoken', 'django_fsm', 'django_celery_results', 'django_celery_beat', 'schedule', 'core', 'ops', 'cdg', 'workflow', 'api_app', 'assignment_classifier', 'dictionary', 'knowledge_base', 'scheduler', 'memoize', # function caching 'api_models', ) Running "python setup.py install" appears to work as desired.

Iterate through similar model field names in template (e.g. FieldName1, FieldName2, etc.)
Fairly new to Django and Python, but trying my best to learn how to clean my code. Currently, I have a model called Recipe that can hold 30 steps (Field Names = Step1, Step2, etc.) and 30 ingredients (Field Names = Ingredient1, Ingredient2, etc.) amongst other fields. The snippet of code below works great, but I am currently manually doing this for all 30 table rows up to Step30, Ingredient30, etc. I've tried setting up a for loop that places {{ i }} at the end of the Field Name to generate up to 30, but am generating parsing issues. I've also tried placing the Field Names in a list or dictionary and looping through them that way, but ultimately will only generate the name of the string, not the attributes value. Below is my setup, which as I mentioned currently works.

Custom User Authentication For Json gives error

Customise BootstrapDateTimePickerInput
This is my registration form. The ridiculous date format allows me to differentiate between my custom made format and more generic ones. models.py class User(AbstractBaseUser): d_o_b = models.DateField(default=timezone.now()-datetime.timedelta(days=6570)) 6570 is 18 * 365 forms.py widgets = {'d_o_b': BootstrapDateTimePickerInput(format='%d/%d/%m/%m/%m/%m/%Y', attrs={'class':'datepicker-start'})} When I change the date, the date format changes to an American style one. When I change the date, I want my custom made formatting to remain. And I also want to stop users being able to select dates pre 2000. boostrap_datetimepicker.html This was the default code (minus the date format which I modified). {% include "django/forms/widgets/input.html" %} <div class="input-group-append" data-target="#{{ widget.datetimepicker_id }}" data-toggle="datetimepicker"> <div style='background-color:blue' class="input-group-text"><i class="fa fa-calendar"></i></div> </div> </div> <script> $(function () { $("#{{ widget.datetimepicker_id }}").datetimepicker({ format: 'DD/DD/MM/MMM/YYYY/', }); }); </script> I thought the function widget.datetimepicker_id would run every time you chose a date. I thought you used this function to determine how your date could appear on the screen. But the function only seems to have any effect first time you load the page and only when d_o_b has a default value. And if you have (a) widgets = {'d_o_b': BootstrapDateTimePickerInput(format='%d/%d/%m/%m/%m/%m/%Y', attrs={'class':'datepicker-start'})} as oppose to (b) widgets = {'d_o_b': BootstrapDateTimePickerInput()} then the function widget.datetimepicker_id also seems to have … -

I have two class in my models.py file: class Asset(models.Model): name = models.CharField(max_length=250) short_name = models.CharField(max_length=100) class AssetTimeSeries(models.Model): asset= models.ForeignKey(Asset, on_delete=models.CASCADE,) date = models.DateField() contribution = models.DecimalField(max_digits=12, decimal_places=2) irr_value = models.DecimalField(max_digits=9, decimal_places=4) quarter_highlights = models.TextField() and I defined views.py code like this: class AssetDetailView(DetailView): model = Asset context_object_name = 'asset' template_name = 'asset/asset_detail.html' and this is the asset_detail.html file: {% block content %} <div class="asset-detail"> <h2>{{ asset.name }}</h2> <p>Short name: {{ asset.short_name }}</p> {% for asset_time_series in asset.asset.all %} <p>{{ asset_time_series.quarter_highlights }}</p> <p>{{ asset_time_series.irr_value}}</p> {% endfor %} <div> <h3>Asset history</h3> <table class="table"> <thead class="thead-dark"> <tr> <th scope="col">#</th> <th scope="col">Date</th> <th scope="col">Contribution</th> </tr> </thead> <tbody> {% for asset_time_series in asset.asset.all %} <tr> <td>#</td> <td>{{ asset_time_series.date }}</td> <td>{{ asset_time_series.contribution }}</td> </tr> {% endfor %} </tbody> </table> </div> </div> {% endblock content %} Is there a clever way to get last inserted values of the AssetTimeSeries object related to an Asset objects? I mean can I rewrite this code to show me only the last values? instead of all the values? {% for asset_time_series in asset.asset.all %} <p>{{ asset_time_series.quarter_highlights }}</p> <p>{{ asset_time_series.irr_value}}</p> {% endfor %} -
