Why Python doesn´t save my model to database using object .save()?
I have a function in views.py accepting petitions that get some text and a book pk and save the text to a fragments table and update the book text with the new fragment.

Is it correct to put non-data related methods into Django model?
My colleague and I are discussing whether it is correct to have model methods which are not directly related to the model data. For example, methods that generate links for the admin pages. Should these methods be in the model or it can be a separate function which accepts app_name as an argument? class Resource(models.Model): ... @classmethod def __admin_list_url(cls): return reverse(f'admin:{cls._meta.db_table}_changelist') @classmethod def get_admin_list_url(cls, caption='', query_string=''): if not caption: return '-' return mark_safe(f'<a href="{cls.__admin_list_url()}{query_string}" target="_blank">{caption}</a>') -

Adding hours,minutes through datetime.timedelta not working?
Here I have some functions for managing leaves.I send the leaves by using django forms and which worked. But the problem is while viewing leave_detail in the function def view_your_leave_detail(request,pk): It is giving me this error: Exception Value: 'datetime.timedelta' object has no attribute 'hours' I think the one problem is while saving the Leave model I have specified start_day and end_date as the DateTimeField but I saved only dates but not times while saving the form. If it is the issue then how can I set times only auto but not date. Also with these functions, if the leave request has been accepted by the function def accept_leave(request,pk): then in the function def view_your_leave_detail(request,pk): I want to display some message like You have 1 day 1 hours 30 minutes and 30 sec remaining if leave is not completed but if leave is completed then your leave is completed message.For this I tried like this ,Is there any mistakes in my approach ? models.py class Leave(models.Model): staff = models.ForeignKey(get_user_model(),on_delete=models.CASCADE,related_name='staff_leave') organization = models.ForeignKey(Organization,on_delete=models.CASCADE,related_name='staff_leave') sub = models.CharField(max_length=300) msg = models.TextField() start_day = models.DateTimeField() end_day = models.DateTimeField() is_accepted = models.BooleanField(default=False) is_rejected = models.BooleanField(default=False) sent_on = models.DateTimeField(auto_now_add=True) views.py def send_leave_request(request): form = MakeLeaveForm() if request.method … -
How to perform select_for_update in Django Rest Framework
I have a requirement where users will be selecting a few rows from the front end table. (In my case it is React and Antd is the UI library). When the user selects a row or rows from the frontend, those row information will be passed from frontend to the backend through ajax call, and those rows should be locked in the backend so that no other user can access the selected rows. If the rows are selected at the same time by some other user then a warning response should be sent to the user. For the backend, I'm using Django Rest Framework. I'm somewhat familiar with Django and Django Rest Framework on function-based view. For locking a row I know I've to use select_for_update method but I'm not sure how to implement it for multiple rows. Can anyone please give me backend(i.e. Django Rest Framework) code example how to achieve this. -

Getting "Unhandled Promise Rejection: Network Error.." when using axios on a real android device
I am experiencing a problem where I cannot fetch data using axios. To give a brief background, I am using django and django rest framework for my backend. I tried many solutions online but none of it solve the problem I have right now. The API is working properly on android and ios simulator with a slight change with the endpoint (10.0.2.2 for android, localhost for ios). Although whenever I test it on an actual android device, the problem is still reoccurring. What I have tried so far: Changing axios' endpoint to my IP Address (192.168....) Adding django cors header in my django project Adding content-type header to axios Although there's an odd behavior whenever I'm fetching through 10.0.2.2 endpoint. I receive the warning/error very late, usually around 1-2 mins. Any help would be greatly appreciated. Thanks!

Django Model auto modified date issue
I have a model with these two fields among others - last_synced = models.DateTimeField(null=True, editable=False) modified = models.DateTimeField(auto_now=True) last_synced is null by default and modified date is updated everytime the model is updated. I have a get_syncable_models in my Model Manager which returns all rows, for which the modified date is greater than last_synced date def get_syncable_models(self): return self.filter( Q(modified__gt=F('last_synced')) | Q(last_synced__isnull=True), reviewed=True, ) The get_syncable_models functions is called by a batch process and updates all the models with last_synced = timezone.now() . However, while saving the modified date is greater than the last_synced date(because timezone.now() in the Django framework is called few milliseconds after timezone.now() is called in the application layer), so get_syncable_models function will effectively work only when last_synced is null. I am thinking of two options here - Write a save method and check if the last_synced has been changed and then add a second to the modified date. Add a "sync" flag in the model, which will be set to true by the batch job. Based on this flag, the code will add a second to the modified date. Would much appreciate if there is a cleaner Django solution? -
