How to write log records to existing error log file
The error log that my django error's get written to is highly accessible. As a result, within my code, I'd like to use this same file for my logging. My configuration looks like this. Settings.py LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'handlers': { 'file': { 'level': 'ERROR', 'class': 'logging.FileHandler', 'filename': '/opt/python/log/djangoerrors.log' }, }, 'loggers': { 'django': { 'handlers': ['file'], 'level': 'ERROR', 'propagate': True, }, }, } Within my view, I've got this: import logging logger = logging.getLogger(__name__) def myview(request): ... some code ... logger.error('hello. This should be logged to the error file.') Unfortunately, this text isn't being written to my djangoerrors.log file. Can you see what I'm missing? Thanks! -

How do I headlessly create a page in Wagtail?
Is there any way I mimic the Wagtail behaviour of creating pages? The only way that I can think of is to totally replicate the POST request sent by them upon clicking 'Publish' in the admin interface, but that would be just hideous. I need this because I need to get a product list from an api, treat them and insert them in my DB. I would prefer to do this through wagtail so I do not drift away from my CMS In a perfect world this would be a call to some api endpoint where I provide the needed fields in the body of the request. -
Django - creating a random page selector

How to test django (3.0) CreateView's 'form_valid' method and parameters with a test client?
Some info In order to make some "current-logged-in-user" info available across multiple views and apps, I stored they're keys in session, which is available via any request instance I used class based CreateView to create an object with a ModelForm I've created I wanted to use some object's key in session inside the CreateView's valid_form method The valid_form method is called from post, so in order to pass request to valid_form, I overrode post and valid_form, as seen below What I'm trying to do I want to test the valid_form instance, specifically its request value. To do so, I'm using Django's test client. Do note, I'm NOT trying to test a ModelForm instance, I'm trying to test the view and test the valid_form method (and its parameters).

Django - failed registration, displaying reason back to user
I'm using the built in django user model, but having trouble feeding back to the user why their registration details are failing. In this example, i'm trying to display the reason back to the user, for why there registration has failed. For example, not meeting the models password requirements, existing user etc. I have... # forms.py - so they supply their email address for verification class CustomUserCreationForm(UserCreationForm): class Meta(UserCreationForm.Meta): fields = UserCreationForm.Meta.fields + ("email",) # views.py def register(request): if request.method == "GET": return render( request, "users/register.html", {"form": CustomUserCreationForm} ) elif request.method == "POST": form = CustomUserCreationForm(request.POST) if form.is_valid(): user = form.save(commit=False) user.is_valid = False user.save() else: messages.info(request, 'invalid registration details') return render(request, "users/register.html", {"form": CustomUserCreationForm}) How do I find out why forms.if_valid() fails, and pass it back to the user? At the moment, it just gives a generic message back, with no user feedback as to why it didn't work. Thanks -
Foreign Key to two different Django Models
For my CRM I am trying to create an History model, that should store every change or action made on a specific Ticket (aka Customer Request). In this scenario two type of users are involved: Resources and Customers. Since both can make an action that should be stored in the History table (ex. Customers can open the ticket and Resources can close it) I was wondering what is the right way to achieve this as a Foreign Key (actor) class TicketHistory(models.Model): ticket = models.ForeignKey("Tickets", on_delete=models.PROTECT, related_name="ticket") action = models.ForeignKey("HistoryActions", on_delete=models.PROTECT, related_name="action") resourceActor = models.ForeignKey("Resources", ...) customerActor = models.ForeignKey("CustomerUsers" ...) date = models.DateTimeField(auto_now_add=True) As you can see I've initially decided to create two different fields, but I don't think it is the best solution. How would you do this? -
Storing TimeSeries data with a django application in addition to using PostresQL based on performance
I need some advice. After extensive research I still don't have a clear straightforward answer. I am runnning a django app with a PostgresQL DB (AWS RDS) and I am storing TimeSeries data there and I am using REST framework as API tech. Right now I am storing the time-series data with json-fields in the PostgresQl DB. My model could be simplified like this: class TimeSeries(..): data_json = JSONField( help_text="Data for time series in JSON format. Valid JSON expected." ) Let's say in a loop I send about 30 time-series objects with about 8760 (hours p year) values in the json field ({"1":"23.12", ... {"8760":"234.11"}) the script to create the objects needs about 3min. When I send 30 time-series objects with about 525 600 values (minutes p year) the script to create the objects takes about 1hour!! To query all this data back it also takes me roughly 3-4 minutes. This is by far too long. And it won't stay with 30 objects but will increase significantly. I will create/update the hourly/minute data every day or week. I want to reduce at least the query-time to seconds or even better be instantaneously. But also the creation time. But I don't …
