Django FormView with dynamic forms
I created the FormView below that will dynamically return a form class based on what step in the process that the user is in. I'm having trouble with the get_form method. It returns the correct form class in a get request, but the post request isn't working. tournament_form_dict = { '1':TournamentCreationForm, '2':TournamentDateForm, '3':TournamentTimeForm, '4':TournamentLocationForm, '5':TournamentRestrictionForm, '6':TournamentSectionForm, '7':TournamentSectionRestrictionForm, '8':TournamentSectionRoundForm,} class CreateTournament(FormView): template_name = 'events/create_tournament_step.html' def __init__(self, *args, **kwargs): form_class = self.get_form() success_url = self.get_success_url() super(CreateTournament, self).__init__(*args, **kwargs) def get_form(self, **kwargs): if 'step' not in kwargs: step = '1' else: step = kwargs['step'] return tournament_form_dict[step] def get_success_url(self, **kwargs): if 'step' not in kwargs: step = 1 else: step = int(kwargs['step']) step += 1 if 'record_id' not in kwargs: record_id = 0 else: record_id = int(kwargs['record_id']) return 'events/tournaments/create/%d/%d/' % (record_id, step) The post request fails at the django\views\generic\edit.py at the get_form line, which I realize is because I've overwritten it in my FormView: def post(self, request, *args, **kwargs): """ Handle POST requests: instantiate a form instance with the passed POST variables and then check if it's valid. """ form = self.get_form() if form.is_valid(): … return self.form_valid(form) else: return self.form_invalid(form) However, when I change the name of my custom get_form method to say gen_form, … -

Custom widget for DateTime picking doesn't appear in my django admin page

How to add dynamic search filters with django-taggit
I want to add dynamic search filters to my django-taggit tags using checkboxes next to my search form, so that a user can enter a query, select one or multiple checkboxes and get the result of any product that contains the selected value(s).

Exclude instance when updating Recursive Foreign Key in Django
I have the following model and modelform for an Employee: models.py class Employee(models.Model): reports_to = models.ForeignKey( 'self', on_delete=models.SET_NULL, null=True, blank=True) forms.py class EmployeeForm(forms.ModelForm): class Meta: model = Employee The idea is that the boss of an Employee is themselves an Employee. The problem is that, when I'm updating the instance, the respective form field created is a dropdown with all Employees, including the object I'm updating itself. Is there an easy way to remove the instance itself from the dropdown options so that no employee has him/herself as their own boss? PS.: I'm not looking for a solution that validates the form field after submitting a form, but rather removing the option from the form dropdown altogether. Thanks! -

How to render a form as dropdown menu
In Django I cant get a form to appear on the html page despite several attempted solutions. The goal is to creat a simple dropdown menu from a database content.

Returning 401 on Invalid Grant in django-oauth-toolkit
I am using Django and django-oauth-toolkit==1.2.0. Whenever I try to refresh a token twice, I get (as it should) an invalid_grant response. This is a 400 BAD REQUEST response. I would like this to be a 401 UNAUTHORIZED response. How can I change this in the toolkit?

How can I get the logined in user details in django 2 models?
Sorry, I am still in a very beginning stage of Django. I have created a model for task scheduling. The model is registered it in admin.py. The Tasks will be assigned manually to some assignee from the main list of operators (users). Now I would like to track the change of the task form in the Django admin. I managed to track the time of change but I would like to get the login user first and last names and assign them to this method below instead of the "assignee.first_name & assignee.last_name" def str(self): return "%s last edit at %s by %s %s" % (self.title, datetime.now().strftime('%Y-%m-%d %H:%M:%S'), self.assignee.first_name, self.assignee.last_name,) Here is my model: '''''''' class Operator(User): # full_name=User.get_full_name class Meta: ordering = ('first_name', ) proxy = True class Task( models.Model): # assignee = User.first_name + ' ' + User.last_name assignee = models.ForeignKey(User, on_delete=models.PROTECT, null=True, related_name="assigned_tasks", related_query_name="assigned_task", ) creation_datetime = models.DateTimeField(default=datetime.now().strftime('%Y-%m-%d %H:%M:%S')) title = models.CharField(max_length=200) description = models.TextField() start_time = models.DateTimeField() end_time = models.DateTimeField() def __str__(self): return "%s last edit at %s by %s %s" % (self.title, datetime.now().strftime('%Y-%m-%d %H:%M:%S'), self.assignee.first_name, self.assignee.last_name,) '''''''' -
how to prefetch parents of a child on mptt tree with django prefetch_related?
Say, I've got a product instance. Product instance linked to 4th level child category. If I only want to get root category and 4th level child category the query below is enough to fetch data with minimum database queries: Product.objects.filter(active=True).prefetch_related('category__root', 'category') If I have to reach parents of this product's category and using get_ancestors() method for this, nearly three times mode database query happening. If I write query like below instead using get_ancestors() method, database queries stays low. Product.objects.filter(active=True).prefetch_related( 'category__root', 'category', 'category__parent', 'category__parent__parent', 'category__parent__parent__parent', 'category__parent__parent__parent__parent') But this query is not effective when level of depth is unknown. Is there a way to prefetch parents dynamically in the query above? -
AJAX-driven forms in Bootstrap modals and Django Allauth
I've found a great looking package which integrates Django with AJAX-driven forms in Bootstrap 4 modals, but I'm struggling to get it to work with allauth. One example in the modal package documentation uses the default django signup form, which you can see at the live demo here: https://github.com/trco/django-bootstrap-modal-forms I've tried to copy the package's signup example by substituting out the default signup form with allauth's signup form, but with no luck. I thought the issue must be in part because the default signup form is a ModelForm, while allauth's isn't. So I had a go at turning the django allauth signup form into a ModelForm and then figuring out if there's a way to override the allauth signup form save method but, again, no luck. Here's some of my code plus the package's mixin and the allauth signup form save method - any ideas how allauth could be integrated with this package, if at all? forms.py from bootstrap_modal_forms.mixins import PopRequestMixin, CreateUpdateAjaxMixin from allauth.account.forms import SignupForm class CustomSignupForm(PopRequestMixin, CreateUpdateAjaxMixin, SignupForm, forms.ModelForm): class Meta: model = CustomUser fields = ('username', 'email') views.py from bootstrap_modal_forms.generic import BSModalCreateView class signup(BSModalCreateView): form_class = CustomSignupForm template_name = 'users/signup2.html' success_message = 'Success: Sign up succeeded.

logic of saving a notification object django websockets
I am having a hard time wrapping my head around how to save notifications when a message is received from another other_user in a 2-person Django Channels websockets chat application. Right now I have a function def create_notification that is called after def create_chat_message. def create_chat_message creates a new ChatMessage object each time a new message is sent in the Thread. It takes args thread=thread_obj, user=me, message=msg So obviously each individual message is saved with the user than sent it. def create_notification takes the last object by id in ChatMessage and creates a new Notification object. created_notification = Notification.objects.create(notification_user=user, notification_chat=last_chat) So essentially, the person who sends the message is associated with the notification_user field in the Notification model and saved along with the ChatMessage id. But if I send a message to Tom, my sent message should only be associated with a notification for Tom, not for myself. When I go to render out the notification objects, I get a list of all of them, including notifications for messages I've sent obviously. How can I render out all notifications for each thread I am in with various users? Am I saving these wrong? Should I configure the save notification function … -
Django tries to INSERT instead of UPDATE on save()
I have a model class Device(models.Model): dev_id = models.AutoField(db_column='dev_id', primary_key=True) ... A view locates an object: device = DeviceAdmin.objects.get(uuid=uuid) then it makes some changes (or maybe not) if (...): device.os_type = 'windows' ... then it tries to save any changes: device.save() Here's where Django attempts to insert anther row instead of updating, causing a DB error django.db.utils.IntegrityError: duplicate key value violates unique constraint There's a kind of similar question with solution: Once I set the primary_key field to an AutoField, the issue went away. However, my primary key is already an AutoField. So I stepped through django code with debugger, and fund this in file ...site-packages\django\models\base.py: # If possible, try an UPDATE.

A way to retrieve data in a survey form
Is there a way to retrieve a specific step in a survey wizard knowing that i'm using session to link steps in the survey and i don't store user id in the database.The idea is that a user that stopped in a step in the wizard will get an email sometime later with an URL that will redirect him to where he left on the survey...I don't know how he will get back where he left since the session is already expired .. i think i need to generate a session_key for every session created and add it in the URL but i don't know if that possible since in the documentation it says **The Django sessions framework is entirely, and solely, cookie-based. It does not fall back to putting session IDs in URLs as a last resort, as PHP does. ** -

Aggregation along with extra values
I'm trying to get the aggregate along with its id.

So Basically I need to retrieve id of max correlation for all the companies. I tried Index.objects.values('company').annotate(correlation_max = Max('correlation')). Index.objects.values('company', 'id').annotate(correlation_max = Max('correlation')). None of them are working. I couldn't able to get the id. I checked this. but I need id as well. -

Django development server shutdown on error
I am running a dev server on localhost to test a django app. About a week ago the dev server started exiting on error- which is not ideal. To give you an instance, imagine I want to create a new view, I make my template, then I add the following in urls: urlpatterns = [ ... path('forgotten-password', ForgottenPassword.as_view(), name='forgotten_password'), ] I haven't yet created the ForgottenPassword class based view yet, so rightly the server throws the error: File "/code/accounts/urls.py", line 19, in <module> path('forgotten-password', ForgottenPassword.as_view(), name='forgotten_password'), NameError: name 'ForgottenPassword' is not defined The server then quits however. This is not the desired behavior. I expect the server to remain in an error state until i fix the error (this happened up to about a week ago). What causes this to happen, and how can i ensure that the dev server stays live on an error to avoid having to relaunch the entire app? NB. It was around the same time that we upgraded from django 2.1 to 2.2, is this a desired behaviour in 2.2? NB. II I am aware of this question in which a very similar problem is outlined, but I am running the dev server on ubuntu, … -
Why my angular HTTP request can't GET on local Django server?
I made an Angular application able use an online api to get a json and do stuff. But, although the json is the same, if I try to change only the url of the json by setting a local url of a server written in django, angular would seem not to connect anymore ... My question is, why if with an online cloud server works, with a local one wouldn't? I tried making this server "on cloud" opening the router's port, also setting up a ddns, and using postman or a browser it seems to work, but when i try to connect with angular it still doesn't get the data... I am sure 100% that the server answer, with the right json data, because django prints on console that he received a HTTP GET request : http://i.imgur.com/TIQnIcR.png I remind you that the HTTP angular request worked with another api, but i will still show up some code : export class ProdottoService { private prodotti: Array<ProdottoModel>; constructor(private httpClient: HttpClient) { this.prodotti = new Array<ProdottoModel>(); var url:string = "https://gist.githubusercontent.com/saniyusuf/406b843afdfb9c6a86e25753fe2761f4/raw/523c324c7fcc36efab8224f9ebb7556c09b69a14/Film.JSON"; var local_url:string = "http://127.0.0.1:8000/films/?format=json"; httpClient.get(local_url) .subscribe((films : Array<Object> ) => { films.forEach((film => { this.prodotti.push(new ProdottoModel(film)); })); } ); } getProdotti(): Array<ProdottoModel> { … -
How do I implement autocomplete in my django chatbot?
I have implemented a chatbot based on this tutorial (https://github.com/vaisaghvt/django-bot-server-tutorial/tree/websockets). I would like to implement an autocomplete functionality, so that as I type, options are displayed. An example usage is the bot asking the user "What city do you live in?". I should be able to type "Be" and the bot suggests "Berlin". I understand that I should be able to use "autocomplete-light" for this but unsure about the implementation.
