JWTAuthentication not getting called
I am still new to django, trying to implement JWTAuthentication. Wrote a custom class and added it in the AUTHENTICATION_BACKENDS in settings.py. The authenticate method in this class has request as a parameter. My questions are: 1. How exactly does the flow work? 2. How does django know to pass request to the authenticate method? 3. Unrelated question, I am adding the jwt token using "request.session["Authorization"] = "Token " + jwt_token. Is this the correct way? -

Filter Different log level messages to different log files
So, I am trying to create a logging system for my Django Project where I need to save all the different log level messages to different files. TLDR, I managed to get the Logs for particular level to appear in their respective files, but Debug.log contains all the log level messages Info.log contains all log level messages leaving debug warning.log contains WARN, ERROR & CRITICAL log level messages error.log contains ERROR & CRITICAL log level messages critical.log contains just CRITICAL log level messages So, I followed the official https://docs.djangoproject.com/en/2.2/topics/logging/ Got a clearer picture from this Django rest framework logging different levels on different files Then wrote the following code. LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'formatters': { 'verbose': { 'format': '%(levelname)s %(asctime)s %(module)s %(process)d %(thread)d %(message)s' }, 'simple': { 'format': '%(levelname)s %(message)s' }, }, 'handlers': { 'debug_logs': { 'level': 'DEBUG', 'class': 'logging.FileHandler', 'filename': 'logs/debug.log', 'formatter': 'verbose', }, 'error_logs': { 'level': 'ERROR', 'class': 'logging.FileHandler', 'filename': 'logs/error.log', 'formatter': 'verbose', }, 'warn_logs': { 'level': 'WARN', 'class': 'logging.FileHandler', 'filename': 'logs/warn.log', 'formatter': 'verbose', }, 'info_logs': { 'level': 'INFO', 'class': 'logging.FileHandler', 'filename': 'logs/info.log', 'formatter': 'verbose', }, 'critical_logs': { 'level': 'CRITICAL', 'class': 'logging.FileHandler', 'filename': 'logs/critical.log', 'formatter': 'verbose', }, }, 'loggers': { '': { 'handlers': ['error_logs', 'warn_logs', … -

Django Schedule Appointment Form Issue
I am creating a form where a user can click a time slot and reserve that time slot. There are 5 columns, one for each day of the week (mon, tues, wed, etc..) with 5 rows of times slots (3pm, 4pm, 5pm, 6pm, 7pm). Each time slot represents a radio input checkbox choice.

How to add dynamic search filters with django-taggit and elasticsearch

How does django cache_page expire?
You set cache_page(60sec) for an endpoint, We assume the endpoint is requested every 5 sec Does the cache reset the timer for expiration every 5 sec , resulting in never expiring cache? Or does it expire after 60sec? -
Cannot Access Form Values With Python View in Django

In Django how to update multiple objects dynamically with values from dict
I have two models model1 and model2 and model1 have a field which is a foreign key pointing to model2. Also, I have a model1_model2_dict with keys as model1.id and value as model2.id. Now I am trying to bulk update the model1.model2_id field using the model1_model2_dict. I tried like this model1.objects.filter(model2_id=None).update(model2_id=model1_model2_dict.get(F('id'), None)) this statement resulted in the update count that I expected, but it actually did not update with model2_id instead it updated with None. Any help on how to make this work? -
Displaying ManyToManyField on Django Page
I'm trying to create a blog on Django, which on a blog post I can add one or more events and list them. For example: Blog Post A has Event1 and Event2 Blog Post B has Event 1 and Event 3 The main area I'm struggling with, is getting this code to actually show up on the page. I've tried a combination of things. The data shows up in the admin + database, but not on the front-end page On the Model I'm showing the below class Event(models.Model): eventname = models.CharField(max_length=150) location = models.CharField(max_length=150) eventdate = models.DateField(blank=False) eventlink = models.URLField(max_length=800) class Post(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, default=1) title = models.CharField(max_length=120) slug = models.SlugField(unique=True) image = models.ImageField(upload_to=upload_location, null=True, blank=True, width_field="width_field", height_field="height_field") height_field = models.IntegerField(default=0) width_field = models.IntegerField(default=0) content = models.TextField() draft = models.BooleanField(default=False) publish = models.DateField(auto_now=False, auto_now_add=False) updated = models.DateTimeField(auto_now=True, auto_now_add=False) timestamp = models.DateTimeField(auto_now=False, auto_now_add=True) eventlist = models.ManyToManyField(Event) On the HTML I'm showing the below <h3> {{ post.listevents.eventname }} </h3> I expect the output to show the Event Name field on the page -
Django Rest Framework model serializer field level validation
I have a DRF ModelSerializer, and I'm trying to override the validation, to no avail. The reason to override the validation is that the corresponding model field is a postgresql HStoreField, so effectively a python dict. However, the incoming data is an array, and I build the corresponding dict during the create function. Serializer: class ReportSerializer(serializers.ModelSerializer): class Meta: model = Report fields = "__all__" def create(self, validated_data): codes = validated_data.pop("report") report = {code: translate_code(code) for code in codes} return Report(**validated_data, report=report) def validate_report(self, value): print("called") return type(value) == type([]) # I know this is hacky So the idea is to translate all of the codes to their respective translations, and save that as a key value pair. This is because I will always need the code and its translation together, and from a performance standpoint it makes more sense to do this once and save it in the db, rather than doing the translation on read. tl;dr: Model field expects dict, data is actually list, I'm trying to override the validation of this field on the serializer to accept this. Unfortunately, the validate_report function never seems to be called, and I'm not sure why. -
Why is the Django admin having trouble with underscores and hex characters in primary keys?
When I click certain links in the admin page of my application, I'm getting errors that look like this: "Object with ID "12345-2Q2019-SCAâA" doesn't exist. Perhaps it was deleted?" The primary key of the record (which is displayed on the link) is actually this: 12345-2Q2019-SCA_E2A Any record that contains an underscore, followed by a capital A-F, gives this error. It seems that Django is wanting to encode the underscore and the trailing letters to a hex character, and since the PK with the hex character isn't present in the database, Django can't find the record and won't redirect to my object's change form. I've tried casting this PK to a string the models by overriding the get_admin_url() method: # models.py def get_admin_url(self): content_type = ContentType.objects.get_for_model(self.__class__) return reverse("admin:%s_%s_change" % (content_type.app_label, content_type.model), args=(self.id,)) And in the admin file by manually creating the url using format_html: # admin.py def url_for_result(self, result): pk = Object.objects.get(id=result.id) html_string = format_html(u'<a href="/admin/project/object/{}/change/">{}', pk.id, pk.id) return html_string list_display = ('url_for_result',) Still, I'm unable to get the links with these 'hex' characters to link to their change form pages. My DB, server, and settings.py files all strictly define UTF8 encoding. Does Django encode/decode these hex characters somewhere, or is … -

How can user registration form for base django user model create ForeignKey user
I am new to django and am trying to set up a simple employee timesheet site that has multiple users. I set up two models one for the individual employee that has a ForeignKey of the base django user and a timesheet model that has a ForeignKey of the employee model. I'm not sure this is correct because when I use my registration form it just creates the base django user and not the "Employee" so when I want to create a new timesheet entry only the one employee is set up (set up with admin page).

Image loading is too slow in Django imagekit
The below code snippet is how I use Django imagekit. I use many images on my website, but the initial loading is pretty slow because of image caching. So, if a page has images that have never been loaded, then it take about 5 seconds to be loadded, otherwise it gets loaded within a second. Just to make sure, there is no problem for image resizing as most of them are under 10kb and about a hundred images are loaded in a page. I feel like the image caching should happen when the image is uploaded so that I don't need to have image caching when I go to a page on my website. Is it possible to be done with Django imagekit? thumbnail.py from imagekit import ImageSpec, register from imagekit.processors import Thumbnail class ArticleHeadlineSmall(ImageSpec): processors = [Thumbnail(430)] format = 'JPEG' options = {'quality': 60} register.generator('thumbnail:article_headline_small', ArticleHeadlineSmall) ...

Get session information in generic view, to use in filtered queryset
So I am trying to list the team members of a current team in django.
