Exception Value: Generic detail view TransactionDetailView must be called with either an object pk or a slug
This error arises when I attempt to visit the Transaction Detail page from my Transaction List page. I am using a UUID (primary=true) as the PK for the Transaction Detail page.

Django - Pagination in DRF returns an error in VueJS
Currently I'm using Vue in my JS file to consume my DRF APIs. Now when I add; 'DEFAULT_PAGINATION_CLASS': 'rest_framework.pagination.PageNumberPagination', 'PAGE_SIZE': 100 In the console, an error is being returned; It says; [Vue warn]: Error in render: "TypeError: status is null" (found in <Root>) TypeError: "status is null" In HTML: <select class="form-control" v-model="newJobRequest.status_of_the_job_request" required > <option v-for="status in statusOfTheJobRequests">[[status.type_of_status]]</option> </select> In JS: getStatusOfJobRequest: function() { this.loading = true; this.$http.get(/api/v1/status-of-the-job-request/) .then((response) => { this.statusOfTheJobRequests = response.data; this.loading = false; }) .catch((err) => { this.loading = false; console.log(err); }) } Due to this error, I am blocked on my task to build a pagination in the table. I've also used DataTables in my use case, but due to this error I can't continue and reverted back to the original state. In the Browsable APIs the pagination doesn't have any problems. I've been searching for answers for the last 2 days and didn't find any similar problems regarding this, afaik. -
Nginx with two Djangos with multiple locations

django form not saving updated value
I have the following form save process in my view: if request.method == "POST": form = PersonDetailForm(request.POST, request.FILES, instance=customer) if form.is_valid(): print(form.cleaned_data['first_name']) //prints corrected updated value saved_customer = form.save() print(saved_customer.first_name) //prints the old wrong value The problem is that the form is not saving the updated first name. When I print the cleaned_data is prints the correct updated value, but when I print the result of the saved form (saved_customer) it prints the old first name. What am I doing wrong? -
Updating a User's skills using ManyToManyField in django
I've been stuck on this for a few days (new to django) and can't figure out how to update skills for a specific user model using a ManyToManyField, while simultaneously updating a skill model containing a list of skills. Currently when I enter a value in my SkillForm, it updates the skill model properly and creates a dropdown list of skills for a given CustomUser in the admin. However, I can't figure out how to assign a SPECIFIC skill a particular user.

Django and technical fields
I'm building a data model. I want that each model has some technical fields like: created and updated. I don't like to add those fieds to each model (you know...DRY). I tried to build a parent class with the created and updated fields, and inherit it in the other models, but Django's ORM does not put created and updated fields in the table of the model, instead it creates another table for the two fields and link it to the model via foreign key. That is not what I want. Is there a feasible way? -

Develop a standalone desktop application using Python
I am new to standalone application development in Python. I would like to develop a Standalone Desktop Application using Python, which pops up a window (having various fields and buttons ,etc- like a Forms design in C#) , it should upload 3 files on a 3 different buttons and verifies if the data of the file is correct. Since Python is vast, I would like to know if there is any Framework or tool that can be used with Python or can i do it exclusively in pure python? Also, can i use Django in this case or is it only for front end web development? Thank you. -
Database model custom JSONField values persisting between test cases
I'm using a Django database model to store objects corresponding to a remote ticket service. In testing this model, I'm running several tests to make sure that log messages work correctly for the database model - I'm using Django-nose to run these tests. The database model looks something like this, using the JSONField from this StackOverflow answer with a small modification to support lists as well as dicts: class TicketEntity(django.db.models.Model) tickets = JSONField(null=True, blank=True, default=[], serialize=True) queued_ticket_data = JSONField(null=True, blank=True, default=[], serialize=True) ... @classmethod def create(cls, *args, **kwargs): instance = cls(*args, **kwargs) instance.save() return instance def queue_output_for_ticket(self, log_data): self.queued_ticket_data += [log_data] self.save() def push_ticket(self): self.tickets += [self.queued_ticket_data] self.queued_ticket_data = [] self.save() return True The tests (in the order they appear to get run) look like this: def test_ticket_entity_push_ticket(self): entity = TicketEntity.create() entity.queue_output_for_ticket("log output") entity.queue_output_for_ticket("more log output") entity.push_ticket() self.assertEquals(entity.tickets, [[log_data, log_data_1]]) self.assertFalse(entity.queued_ticket_data) def test_ticket_entity_queue_output_for_ticket(self): entity = TicketEntity.create() log_data = "Here's some output to log.\nHere's another line of output.\nAnd another." entity.queue_output_for_ticket(log_data) self.assertEquals(entity.queued_ticket_data, [log_data]) The first test passes, perfectly fine. The second test fails on that assert statement, because the entity.queued_ticket_data looks like this: ["log output", "more log output", "Here's some output to log.\nHere's another line of output.\nAnd another."] Those first two elements … -

get_queryset() from a js text input
In this step I'm trying to avoid making a form to send data over to django from the frontend. Ideally I would like to pass a simple string to the queryset with an onclick button, so I can make the tag filters on my Post model and show the ones with the tags from the string input. (just send the string to the queryset, I can deal with the split() and strip() to make it valid) The simplified html would be something like <input type="text" name="tag_filter"> <button type="button" onclick="Tag_Filter()">Filter</button> And the ListView class PostListView(ListView): model = Post #.objects.filter(tags__name__in=["black&white", "red"]).distinct() template_name = 'post/home.html' # <app>/<model>_<viewtype>.html #queryset = Post.objects.all() context_object_name = 'posts' #ordering = ['-date_posted'] def get_queryset(self): tag_list = #the return from the Tag_Filter() js return Post.objects.filter(tags__name__in=tag_list).annotate(num_tags=Count('tags')).filter(num_tags__gte=len(tag_list)).order_by('-date_posted').distinct() -

Django: Fastest way to query & group a queryset by a ManyToManyField
I have two models - a Product & Category. In my template, I want to display the products by the Category. Slow solution The most basic way to do this, query the Categories and in the template loop over the products. {% for category in object_list %} {% for product in category.products.all %} < html to display the product > {% endfor %} {% endfor %} This results in hundreds of queries and is very slow. Question What would be better way to handle this query so that there are as few queries as possible with a faster load time? -

django-moderation inherited fields not moderated
I have a class which extends a class from a 3rd party package (named django-scheduler). from schedule.models import Event from moderation.db import ModeratedModel class Event(Event, ModeratedModel): more_fields = models.TextField() ... The problem is now, that in the django Admin only the fields of my own Event class are getting "moderated". The inherited fields of the Event class from the scheduler package aren't shown in the moderated object... I guess this problem is quite specific for this 3rd party package django-moderation... Or are there any ideas how to tell the ModeratedModel class also to have a look at the "foreign" Event fields? -

Supervisor is throwing an error that it can not access my environment variables: ERROR: CANT_REREAD: Format string '\nSETTINGS="%(ENV_SETTINGS)s"...' for 'environment' contains names ('ENV_SETTINGS') which cannot be expanded. Available names: ENV_HOME, ENV_LANG, ENV_LOGNAME, ENV_PATH, ENV_SHELL, ENV_USER, group_name, here, host_node_name, process_num, program_name in section 'program:app' (file: '/etc/supervisord/supervisord.conf') This problem has been described before (link). When launched as a service, supervisor can not access variables defined in shell configuration files by a particular user. Indeed those variables that it lists as available are just a small subset of what is available to me if I run the env command. Where should I define my secrets as env variables? Should I take them out of /etc/bashrc and define them in the supervisor config file? Or in the gunicorn_start script even (/home/app/bin/gunicorn_start)?
