Django - Celery - How to handle complex tasks
Following problem needs to get solved: In my Django project I have to collect, manipulate and save specific data on regular basis. Example: Every minute I have to retrieve data from a heating-system via REST-API and process them Every minute I have to retieve data from a PV-inverter via REST-API and process them Every six hours I have to retrieve data from an external data provider and do some processing on it. After midnight I have to do some calculation on data from previous day ... and more to come in future From my perspective the Django/Celery/Beat approach would fit for above scenarios. I'm aware it's not a real message-based use case - more a batch processing use case to not setup cronjobs. In my Django project I have created apps (for the specific subsystems) and some general packages on project level. Described scenarios can be called (from Python shell and via Bash script outside development via cronjob. Now I tried to use Celery Beat to orchestrate above scenarios. But I'm not able to call the scripts from inside the celery tasks. Simply nothing happens - I guess importing all packages and scripts fail. I worked with several tutorials to … -

Agents of Faust streaming stop event consumption after some days
I have an application using faust-streaming. The application has around 20 agents each consuming events from different Kafka topics.

How to pass a Django object from template to view by POST request?
I trying to pass the value of a checkbox to my views.py in the following way: my_template.html <input type="checkbox" name="playlist" value='{{ playlist }}'> views.py json_str_list = request.POST.getlist('playlist') The serialized JSON in json_str_list looks like this: '{\'id\': \'UUkfDws3roWo1GaA3pZUzfIQ\', \'title\': "Item 1", \'created_on\': datetime.datetime(2023, 6, 12, 20, 44, 41, 392273, tzinfo=datetime.timezone.utc)}' This seems not to be a valid JSON string.

Django form, dynamic number of fields based on another field
The following is my Django model for different type of questions: class Question(models.Model): QUESTION_TYPES = [ ('SBA', 'Single Best Answer (MCQ)'), ('EMQ', 'Extended Matching (Matching)'), ('SAQ', 'Short Answer Question'), ] question_type = models.CharField(max_length=3, choices=QUESTION_TYPES) class Option(models.Model): question = models.ForeignKey(Question, on_delete=models.CASCADE) option = models.TextField(default="Option") class Subquestion(models.Model): question = models.ForeignKey(Question, on_delete=models.CASCADE) subquestion = models.TextField(default="subquestion") I need a form to create new questions with all relevant fields. The fields needed on the form are dynamically decided based on a field in Question model. If question type if SBA is chosen, there should be 5 options fields (no subquestions) appearing and saving to the related models. If EMQ is chosen there should be 5 subquestions, and 7 options fields appearing. if SAQ is chosen no subquestions and options should appear. I tried using formsets but due to poorly written tutorials I could not understand. As the changes in question type should instantly change the remaining field, I am interesting in dynamic form fields. Any one can help? -

How to let user pick date AND time in the form?
I am trying to create a sort of To Do List. Majority of it is done. I can get user to enter the task, along with its detail and pick the starting and ending date. However, since I am rendering the fields in a form, I want the user to easily and conveniently enter the date and time. For that I have added a datepicker type widget. The datetime stored in database is still in ISO format. Now, the issue is that user can pick or enter the date perfectly fine. But it does not allow the user to enter the time. Once the date has been picked, the user can't enter the time. The code goes as under: class TaskForm(ModelForm): class Meta: model = TaskModel exclude = ["completed"] widgets = { 'title': TextInput(attrs={"class": "form-control"} ), 'detail': Textarea(attrs={"class": "form-control"}), 'start_time': DateInput(format = ['%d/%m/%Y %H:%M'], attrs={"type":"date", 'class': 'form-control datetimepicker-input', 'data-target': '#datetimepicker1'}), 'end_time': DateInput(format = ['%d/%m/%Y %H:%M'], attrs={"type": "date", 'class': 'form-control datetimepicker-input'}) } And the Model.py file is: class TaskModel(models.Model): title = models.CharField(max_length=30) detail = models.TextField(blank=True) start_time = models.DateTimeField() end_time = models.DateTimeField() completed = models.BooleanField(blank = True, null=True) The rest of the code is just simple and conventional Django based views and … -
