how to create product auto Code generator python django
I have a product class in the Django model. Over there are product name, category and department name (foreign key). so I want to create an automatic code generator that will generate automatically like 2 or 3 alphabets as category name and 3 alphabet department name and 6 digits number. for example: COM-ELC-000001 '''class Item(models.Model): item_name = models.CharField(max_length=255, blank =True) description = models.CharField(max_length=255, blank=True, null=True) item_choice = ( ('IT','IT'), ('Electronics', 'Electronics') ) item_type = models.CharField(max_length=255, blank =True, choices = item_choice ) code = models.CharField(unique=True, max_length=255) unit = models.CharField(max_length=255, blank=True, null=True) company = models.ForeignKey(Company, on_delete = models.SET_NULL, null =True,blank=True) department = models.ForeignKey(Department, on_delete = models.SET_NULL,null= True, blank=True) ''' -

Disable gunicorn glogger and use Django LOGGING config
I am having trouble to properly config gunicorn and Django logging to work together. I have managed to make gunicorn pass the errors like 404 /favicon.ico to my Django log however I am not able to catch other levels no matter what I pass as --log-level for gunicorn. Here is the loggers section in my settings.py 'loggers': { 'django': { 'handlers': ['console', 'django_info_file', 'django_error_file'], 'propagate': True, }, 'gunicorn.access': { 'level': 'INFO', 'handlers': ['gunicorn_access'], 'propagate': True, 'qualname': 'gunicorn.access' }, 'gunicorn.error': { 'level': 'INFO', 'handlers': ['gunicorn_error'], 'propagate': True, 'qualname': 'gunicorn.error' } } ... and appropriate handlers 'handlers': { 'console': { 'level': 'DEBUG', 'filters': ['require_debug_true'], 'class': 'logging.StreamHandler', 'formatter': 'simple' }, 'django_info_file': { 'level': 'INFO', 'filters': ['require_debug_false'], 'class': 'logging.FileHandler', 'filename': os.path.join(BASE_DIR, 'project_name/logs/django/info.log'), 'formatter': 'verbose' }, 'django_error_file': { 'level': 'ERROR', 'filters': ['require_debug_false'], 'class': 'logging.FileHandler', 'filename': os.path.join(BASE_DIR, 'project_name/logs/django/error.log'), 'formatter': 'verbose' }, 'gunicorn_access': { 'level': 'INFO', 'filters': ['require_debug_false'], 'class': 'logging.FileHandler', 'filename': os.path.join(BASE_DIR, 'project_name/logs/gunicorn/access.log'), 'formatter': 'verbose' }, 'gunicorn_error': { 'level': 'INFO', 'filters': ['require_debug_false'], 'class': 'logging.FileHandler', 'filename': os.path.join(BASE_DIR, 'project_name/logs/gunicorn/error.log'), 'formatter': 'verbose' } }, So what I have tried so far: --log-level=debug --log-file=- --capture-output --enable-stdio-inheritance --access-logfile=- --error-logfile=- On the Django side I have tried with: 'disable_existing_loggers': True, (both True and False) setting DEBUG=True and False to make sure require_debug_false is … -
Architecture of application using Angular + Django + Flask and How to integrate them?
I am building an application with Angular + Django + Flask, below are the details of the architecture that are finalized for the implementation: We want to read data from MySQL database using flask microservice and show it to the user using angular UI. Django will be used for managing admin functionality. We decided to use flask despite the Django rest framework because of microservices architecture. Jenkins will be used for CI/CD and docker for deployment. What approach should be used if I want my angular UI to be served by Django application as I don't want to run a separate server for it and data in UI to be fed by flask microservice. I am facing a problem with how to integrate them. I have searched a lot but didn't found any good solid solutions. Please guide me on how should I integrate them. -

How to get Django/Wagtail to resolve this url
I feel like a heel asking this because I'm sure the answer is simple. Nevertheless I've spent hours researching and testing possible solutions and I have been left hairless. In the project harmony I have written my own login page and it resides in an app called users. I have another app called your_harmony.

How can I make Django mysqlclient package being detected with mod_wsgi and virtualenv?
I have a Fedora 32 workstation with apache2 and Python 3.8 as default. I want to use it as server for my Django 3 app. I've already installed latest version of mod_wsgi (compatible with python3.8) and it's already enabled in apache modules. But I keep getting an error in apache error_log: django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module. Did you install mysqlclient? The answer is YES, I've installed mysqlclient with pip install mysqlclient (in my virtualenv). And actually it exists: /var/www/virtualenv/lib/python3.8/site-packages/mysqlclient-1.4.6-py3.8.egg-info I think I have an issue in my .conf file for mod_wsgi. It usually worked in another developments that I've made, but I'm not getting the point of why it's not working now. This is my .conf MOD_WSGI settings: WSGIDaemonProcess myapp python-path=/var/www/myproj:/var/www/virtualenv/lib/python3.8/site-packages WSGIProcessGroup myapp WSGIScriptAlias /myapp /var/www/myproj/myproj/wsgi.py I have made the same configurations in another developments in the past, and it worked fine. I thought it would work. It's not a module version issue because when I run it with manage.py runserver it works fine. Using gunicorn is not an option at the moment. I need to get this working with mod_wsgi. Thanks in advance! -
Compatiblilty between Django rest Framework and Bootstrap
Django 3 Bootstrap 4 I have an Django app I've created (not live) and I've used bootstrap to make it nice and pretty (and mobile responsive). My goal is to end up with a react front end, but I'm not very good with react yet. Is it possible to switch to Django Rest Framework and keep bootstrap 4 or is drf and Bootstrap competing technologies? If I can, it'll let me be ready for react when I feel comfortable implementing it -

Django creating ManyToMany relationships

adding detail information to django listview object in template
I have a listview in which I'm hoping to insert additional details about the object (activity duration and average power) in the same row as the link to the object detail (the best way to describe it would be that I want some detailview attributes inserted into the listview). At the moment, the best I can achieve is a separate context dictionary listed below the object_list, as shown in this screen shot: And the following is my listview: class RideDataListView(LoginRequiredMixin, ListView): model = RideData context_object_name='object_list' template_name='PMC/ridedata_list.html' def get_queryset(self): queryset = super(RideDataListView, self).get_queryset() return queryset def get_context_data(self, *args, **kwargs): model = RideData context = super(RideDataListView, self).get_context_data(*args, **kwargs) records = list(RideData.objects.all().values()) actdict2={} id=[] ap=[] actdur=[] for record in records: actdf=pd.DataFrame.from_dict(record) id.append(actdf['id'].iloc[0]) ap.append(actdf['watts'].mean()) actdur.append(str(timedelta(seconds=len(actdf['time'])))) actdf2=pd.DataFrame() actdf2['id']=id actdf2['ap']=ap actdf2['actdur']=actdur actdict2=actdf2.to_dict('records') context['actdict']=actdict2 context['actdur']=actdur return context What I haven't been able to nail down in my research is if there is a way to either a) annotate the queryset with stuff from context or b) loop through the context dictionary 'actdict' within the object_list loop (doesn't seem possible based on some attempts) or c) include individual lists (ap and actdur as additions to to query.

Django uncaught exception when file upload request canceled
I have an async file uploader using Dropzone.js and everything works fine except for a strange server error that appears from time to time when I cancel an upload request. The error is inconsistent, sometimes I get the expected result after canceling the upload request and other times the error shows up in Identical conditions.

How to model an financial accounting system in Django?
The Django application I'm developing for a taxi company has following modules, Trips Customers (who buy products) Vehicles Drivers Each trip is constituted by selecting a customer, a vehicle and a driver along with a few other parameters. I will be recording every single trip, and the revenue generated because of it. I also would like to assign this revenue generated to the individual customer who took the vehicle, and to the vehicle which was used in the trip. Since I would like to have a deeper understanding of the customer's spending and the revenue generated by vehicles. I need to have an Accounts Receivables and a Received statement for each trip. Is there a standard way to achieve this? I believe the similar approach is used in typical e-commerce systems. Any and every help is appreciated. -
Django rest framework, field that is a choice or text
Is there a way to create a field which is A text field, but, with choices. that the choices are the field existing objects? And if the word passed in is not in the existing data, add it? I've looked across all the internet for a field like this or example of it, either in Django or the rest framework, but could not find one. My use for it, for example, would be: class Point(models.Model): location_name = models.TextField(verbose_name="Location name", unique=True, # This would include the existing names. choices=, ) latitude = models.FloatField(name="GDT1Latitude", verbose_name="GDT 1 Latitude", unique=False, max_length=255, blank=False, help_text="Enter the location's Latitude, first when extracting from Google Maps.", default=DEFAULT_VALUE) longitude = models.FloatField(name="GDT1Longitude", verbose_name="GDT 1 Longitude", unique=False, max_length=255, blank=False, help_text="Enter the location's Longitude, second when extracting from Google Maps.", default=DEFAULT_VALUE) So, It could be used when making a post request instead of already typing the latitude, longitude It would be fetched from the exsiting object. -
Count events types per day for different timezones using Django ORM
We have a table that holds multiple events and when they were added. The default timezone used for storing the events is UTC. Eg : class Events: event_type = models.CharField(max_length=45, null=False) date_added = models.DateTimeField(auto_now_add=True) Now, we want to get a per day count of different event types between two dates - start_date and end_date. Eg : for start_date = "2020-03-1" and end_date = "2020-03-31", output should be - [{ "date" : "2020-03-1", "event1" : 200, "event2" : 606, "event3" : 595 }, { "date" : "2020-03-2", "event1" : 357, "event2" : 71, "event3" : 634 }, { "date" : "2020-03-3", "event1" : 106, "event2" : 943, "event3" : 315 }, { "date" : "2020-03-4", "event1" : 187, "event2" : 912, "event3" : 743 }, . . . . { "date" : "2020-03-31", "event1" : 879, "event2" : 292, "event3" : 438 }] Since the users are in different timezones (America, Europe, Asia, etc), we want to convert the timezone as per user before counting the events. Counting in UTC will have wrong counts per day in the user's timezone. Eg : an event created on 3 March, 1:30 am in IST will be shown on 2 March, 8 pm in … -
