Django: def save() in models.py
I'm trying to add the save-function inside my models.py, but it seems I'm doing something wrong. The user has to type the first- and last-name. Without him or her entering any more data, another field inside my models.py should be filled with a combination from these fields. models.py: class Coworker(models.Model): first_name = models.CharField(max_length=50, null=False, blank=False) last_name = models.CharField(max_length=50, null=False, blank=False) full_name = models.CharField(max_length=100, null=False, blank=False) def save(self, *args, **kwargs): self.full_name = self.first_name + " " + self.last_name super().save(*args, **kwargs) Is this even possible?

Django Video Encoding package not converting videos
hey guys I am trying to add the django-video-encoding package, but it doesn't seem to be working. I have followed exactly as per the documentation. Can someone help with checking the code I have if I missed anything? This is the link to the package: https://github.com/escaped/django-video-encoding Can anyone tell me where I went wrong? I couldn't see any tutorials or much info regarding this package but it seems like its the only one there. I have given the path to ffmpeg like this (am not sure whether its the right way). this is in settigs. VIDEO_ENCODING_FFMPEG_PATH = "c:\\ffmpeg\\bin\\ffmpeg.exe" in my signals.py I have this. @receiver(post_save, sender=VideoPost) def convert_video(sender, instance, **kwargs): enqueue(tasks.convert_all_videos, instance._meta.app_label, instance._meta.model_name, instance.pk) print('Done converting!') and this prints after I upload a video, but the conversion is not happening. -
Django initialize model formset with instances
I have following model: class ModelA(models.Model): name = models.CharField(max_length=100) description = models.CharField(max_length=100) And it is used in modelformset: ModelAFormSet = generic_inlineformset_factory( ModelA, form=AddModelAForm, extra=2) where AddModelAForm looks like this: class AddModelAForm(forms.ModelForm): selected = forms.BooleanField(required=False) class Meta: model = ModelA fields = ['id'] and then initialized following way: formset = ModelAFormSet( queryset = ModelA.objects.none(), initial=[{'id':16, 'selected': True}, {'id': 32, 'selected': False}]) I would like to use in template instance, instead of actual model fields. Something like this: {{formset_form.id}} {% with formset_form.instance as modelA %} Name: {{modelA.name}} Description: {{modelA.description}} {{formset_form.selected}} {% endwith %} Which is working with such instantiation of ModelAFormSet: formset = ModelAFormSet(queryset=ModelA.objects.all()) I know I could use change Meta class of AddModelAForm to have fields = ['id', 'name', description'] and then initialize those values. But in this case I can no longer use instance, but regular fields values (e.g. {{formset_form.name.value}}). And because of that I need to have something like this in clean() method of my form: def clean(self): try: del self.errors['name'] del self.errors['description'] except KeyError: pass I'd like to ask if there is any better way to have such formset initialized and doesn't need to remove errors explicitly? -
Django 3.1: OperationalError - No Such Column/Table

Best way to implement background “timer” functionality in Python/Django
I am trying to implement a Django web application (on Python 3.8.5) which allows a user to create “activities” where they define an activity duration and then set the activity status to “In progress”. The POST action to the View writes the new status, the duration and the start time (end time, based on start time and duration is also possible to add here of course). The back-end should then keep track of the duration and automatically change the status to “Finished”. User actions can also change the status to “Finished” before the calculated end time (i.e. the timer no longer needs to be tracked). I am fairly new to Python so I need some advice on the smartest way to implement such a concept? It needs to be efficient and scalable – I’m currently using a Heroku Free account so have limited system resources, but efficiency would also be important for future production implementations of course. I have looked at the Python threading Timer, and this seems to work on a basic level, but I’ve not been able to determine what kind of constraints this places on the system – e.g. whether the spawned Timer thread might prevent the … -
django clear stale cache entry
I am using database as cache backend. CACHES = { 'default': { 'BACKEND': 'django.core.cache.backends.db.DatabaseCache', 'LOCATION': 'cache_table', } } The problem is that after few times, there are stale entries which are not getting cleared up. Do I need to configure something to get them cleared once they are stale (past their expiration date)? Or need to setup some job to clear? I tried using cache.clear(). But it clears up the non-expired entries as well. -
How to hide all forms in a formset except the clicked one in django template
I am new to Django. I recently started to work with Django-formset, I have 12 forms in Django-formset, each form has atleast 20 fields. My requirement is make a user-friendly design. I decided to make 12 buttons in a row corresponding to each form, initially all the forms will be hidden. When I click on one button, let's say first button then only form corresponding to that button will show up in the same page and rest of the forms will hide. If user click on the same button again then the form should collapse, if user click on other button then form corresponding to that button should show and rest of the forms should hide. After a lot of reading online I could not find a solution to this problem but I came to know that I need to use jQuery or javaScript to solve this. Here is what I have tried so far, but it only hide/show the form that I have clicked and not affect other forms. <form action="{% url 'my_formset' %}" method="POST"> {% csrf_token %} {{ formset.management_form }} {{ formset.non_form_errors.as_ul }} <h4> Time </h4> {% for form in formset %} <a id="{{forloop.counter}}-btn" class="btn btn-success mt-2">{{ form.time.value … -

Do I need to use the DRF if I want to handle Token Authentication?
currently I plan on using AWS Cognito to handle my authentication for users. I want to do a simple registration and login. So far, I have created a function which calls cognito's initiate_auth method. Currently my flow works like this: User goes to /signup After filling the form, I create a new user in the cognito backend and send them a verification mail User is redirected to the /login page The login function in the backend calls initiate_auth with the username and password, and retrieves some token information like this {'AccessToken': '***', 'ExpiresIn': 3600, 'TokenType': 'Bearer', 'RefreshToken': '***', 'IdToken': '***'} I believe these tokens are in the JWT format. My question now is, what exactly do I do with this? I know that I need to store this data, securely, somewhere, but I'm not sure what the best practice is. I've heard that these tokens/data need to be saved in cookies in order to access them properly, but I also heard that there are some encryption problems, which is why I was looking for a library which handles this for me. I've come across this library: https://github.com/SimpleJWT/django-rest-framework-simplejwt However, it seems like in order to use this library, I need to … -
setting up server for django project with celery, tensorflow
I am working on a django project where when an image(design pattern) is uploaded, it does below: extract dominant colors and save it for later filtering put the uplaoded image on blender 3d model and render&save it as product image tensorflow extracting features from the image and save it as npy for later similar image search I set up celery to do above tasks and everything worked fine till I set up taks #3(tensorflow). After having task #3 I'm getting caution about memory allocation from tensorflow when starting up celery. So I'm guessing django and celery both runs tensorflow which I think it's waste of memory. I started thinking seperating them for django(A server) and for blender&tensorflow(B Server). My thoughts are: A & B server both have django running and shares the same database. A handles the main website and B handles image processing tasks including blender & tensorflow. when an image is uploaded -> A post to B -> B does work and save the result to shared database. I'm new to setting up this kind of structure and looking for advices. Thanks very much for reading and help.. -
