Concurrency management in django?
not knowing the competition in databases someone told me to be careful not to have a corrupted database I searched a little bit everywhere for information about competition in Django, but I didn't find a favorable answer. Should I be careful about competition when updating the database with a celery task? I have a person who is connected to two different places and uses the same view in Django to change his first name, for example, there is a risk of crashing the database? What are the best ways to manage competition in Django? What should we be aware of? Do you have any documentation a little more precise for in which case we should use it? I take the example I have a task that updates a data in a user's row it contains his first name and a number of users, the user changes his name and the task changes his name or simply the view of Django, now I have an appendix task that will update the number of users that has it. The tasks will it queue up in the database or they'll try to modify the line at the same time. Thank you in advance -
How to reduce the amount of code written when all 'meta' for each view is the same (structure)?
Recently I started refacturing/rewriting my code. I noticed that some parts of my code show alot of similarity, and I'm wondering if I could reduce the amount of code required to get the same functionality. I would like to generate views based on model names I have and give them the same meta attributes where the only difference is the model naming. Currently I have: from finfor import (models, serializers) class clientOrganizationsListCreate(generics.ListCreateAPIView): class meta: queryset = models.clientOrganizations.objects.all() serializer = serializers.clientOrganizationsSerializer class financialSystemsListCreate(generics.ListCreateAPIView): class meta: queryset = models.financialSystems.objects.all() serializer = serializers.financialSystemsSerializer As you can see, the only difference between the two is clientOrganizations <> financialSystems. I have tried the following: from finfor import (models, serializers) from django.apps import apps for model in apps.get_app_config('finfor').models.values(): class f'{model}ListCreate'(generics.ListCreateAPIView): queryset = model.objects.all() serializer_class = serializers[f'{model}Serializer'] and: from finfor import (models, serializers) from django.apps import apps for model in apps.get_app_config('finfor').models.values(): type(f'{model}Serializer', (generics.ListCreateAPIView, ), type('meta', (object, ), { 'queryset': model.objects.all(), 'serializer_class': serializers[f'{model}Serializer'] }) ) I think I'm not using type() properly. Is there a way to generate the classes by iterating a list ['financialSystems', 'clientOrganizations'] or something similiar? -

How to raise error in django model's save instance before storing in database?
I have registered this model into my admin site. What I want to do is that before pressing the save button, I want to validate the email and phone numbers via the 2 validation functions which uses PyPI packages. However, when I enter a invalid email that is non-existent, and then save, the data is still saved in the database. I want to be able to raise an error such that the user will know that he/she entered invalid fields.

How can I paginate sql query result in html page?

ProgrammingError: 1064 while executing inspectdb with django and mysql database

Heroku aggregate metrics from JSON logs
I have a Django application running on Heroku with json logs outputted to papertrail in the following format (examples): {"message_type":"profile", "method":"a", "runtime":1000, "timestamp: 1570524933} {"message_type":"profile", "method":"b", "runtime":1020, "timestamp: 1570524934} {"message_type":"profile", "method":"a", "runtime":2020, "timestamp: 1570524934} For instance, I want to construct a chart on Grafana that can show the mean runtime of methods a and b across the day but am unsure as to how I can run select or run aggregation functions such as (mean, max, min, etc.) using data from papertrail. So far I have looked at setting up an alert on papertrail for certain log criteria that will then ping Graphite Grafana, however this only gives the summed number of events. Does anyone have any input on this can be achieved? -

Django Storages: use 2 media sources

Setting header name in list_filter when referencing foreign key in Django
I have a ProductType and Transaction model. The Transaction model references ProductType using a foreign key. I use list_filter to filter on ProductType in the admin environment for the Transaction model. However, the header name in the list filter is correct, since it calls the filter option "By name" instead of "By product type". How can I update this header name to "By product type"? models.py class ProductType(models.Model): name = models.CharField(max_length=20) class Transaction(models.Model): product_type = models.ForeignKey(ProductType, on_delete=models.CASCADE) admin.py @admin.register(Transaction) class TransactionAdmin(admin.ModelAdmin): list_filter = ['product_type__name']
