Django JWT Auth for custom model
I have a custom user model class User(models.Model): fields... It also has a email, password field among other detail fields. I want to use the simplejwt JWT authorization which takes email and password as input and generates JWT Tokens. Most tutorials include creating a superuser and passing username password of the superuser to get the token, But I want to do this for my custom user model. -
Best way to implement highly customized Django admin action
I'm trying to implement a custom Admin action that creates an OwnerInvoice object based on data from Receivable and Reservation objects. All Receivable and Reservation objects are related to only one Property object. Ideal workflow: Business admin selects property X to bill and shows a list of Reservation objects which are related to property X and haven't been billed yet. Admin can select which Reservation objects should be billed and a breakdown of the Reservation data selected is shown. On the same page, the admin should be able to choose from a list of Receivable objects (all related to property X and not yet billed). After selecting Receivables, a final page shows the breakdown of Reservation and Receivable objects and provides a total. By pressing save, an OwnerInvoice object is created and a PDF (OwnerInvoice method) is generated. The question: How would the StackOverflow community recommend I implement this kind of functionality into the Django admin? Possible ideas I've had but not sure if they would work with the above flow: Extend the OwnerInvoice's application app_index admin template to show a custom table containing Property object information. Use redirects for intermediate pages (using Reservation change_list and Receivable change_list). Extend the … -
Django Serializer saves the object twice

can i launch a jango app from within pycharm without using terminal?
with other projects i've developed i have been able to hit 'run' to launch my application, and then shift+f10 from then on. it seems excessively cumbersome to have to launch the terminal and type python manage.py runserver every time i want to test something... is there a better way? can i write a python file like "run.py" with some script that will launch the app, or some other solution? i've searched for ages, and all i can find is a thousand tutorials telling me how to start a project, rather than how to launch it more easily. thanks -
Auto execute background tasks in django
I am trying to automatically run background tasks as soon as the server starts in django. Specifically, after the server boots and is running on localhost, I want it to run functions that fetch api data to fill my DB. What is the best way to do this? Is it celery? Django-background-tasks is outdated for the lastest version of Django. I am trying to mess around with redis/rq and rq works when attached to a view but I still dont know how to actually have django run anything upon server load. Any guidance would be appreciated. Thank you! -

Instagram followersssssss
I didn’t post a fancy and word-playing title. We are all social media brothers and let’s not fool anyone: I follow who follows! Being followed is a very uncomfortable and dangerous situation. In real life. In digital life, the equation is ‘slightly’ different. Which is disturbing and dangerous; not to be followed. Unfamiliarity of followers is not an inconvenience, but a reason for happiness. We don’t get depressed anymore, we look at a friend whose name is ‘disapproval’ and go out. This is the reality of the world – the digital one – whether we like it or not. I also offer a huge service to dear readers for the needs of the day, and this week I am giving tips on how to increase your followers on Instagram. Use labels. If possible, choose those that encourage mutual following, such as #instafollow, #l4l, followback. Follow those who use these tags. Do not neglect the ‘TagForLikes’ application, which allows you to instantly use the most popular tags practically. Like random photos of different people (Don’t always heart beautiful/handsome people, mix trees/plains together. Your girlfriend sees them). In one experiment, it turned out that for every 100 random photos liked, six followers … -
How to append a list in jinja3
I am new to Django and Python. I have a nested forloop in my html template which removes an item from a list with each loop: {% for item in horizontal_list %} {% with vertical_list=vertical_list.pop %} {% endwith %} {% for item in vertical_list %} {{ form.board }} {% endfor %} {% endfor %} The idea behind it is that I am trying to create a hexboard and with the above loop I am able to achieve the following: O O O O O O O O O O O O In other words, the following peace of code is working as expected in the above example: {% with vertical_list=vertical_list.pop %} {% endwith %} However, for the top half of the board, I need a very similar loop but instead of using pop, I need to append the list: {% with vertical_list=vertical_list.append %} {% endwith %} At the moment, it does not append the list and the end result is similar to: O O O O O O <-------- this list here should be appended O O O O O O O O O O O O I am struggling to understand why pop would work in jinja but not … -

I have a bunch of files for a website and don't know how to put them together
I am running windows and working in Pycharm community edition for a website. I would like to run Docker in CE but I have seen that is not possible since it is only reserved for professional use.

Maybe if there is an easy way rather than just doing everything manually. -

How to filter a Django model to display only the logged-in user's data?
Trying to solve this for a week now. How do I filter my model to display only the data assigned to the specific logged-in user? My views.py code below is not working---it's not telling forms.py what it needs to do to accomplish this. I get the error 'ForwardManyToOneDescriptor' object has no attribute 'option1'. It does filter effectively in the template---but I need to use the RadioSelect widget (defined in forms.py) in order to display specific choices that the specific logged-in user must choose from (and I don't think I can---or should---code that in the template). views.py class VoteView(LoginRequiredMixin, CreateView): model = Result form_class = VotingForm template_name = 'users/vote_form.html' *Attempt #1: def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['Result'] = Result.objects.all() context['user_specific'] = Result.objects.filter (custom_user=self.request.user) return context *Attempt #2: def get_initial(self): initial = super().get_initial() initial.update({'custom_user': self.request.user}) return initial forms.py class VotingForm(forms.ModelForm): def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) choices = [('1', Result.decision.option1), ('2', Result.decision.option2), ] self.fields['vote'] = forms.ChoiceField(choices=choices, label="Choices", widget=forms.RadioSelect()) class Meta: model = Result fields = ['decision', 'vote'] models.py (if needed) class Result(models.Model): custom_user = models.ForeignKey(CustomUser) decision = models.ForeignKey(Decision) * Decision contains decisions and their choices (like 'option1', 'option2') vote = models.CharField() vote_eligible = models.BooleanField(default=False) -

How to load existing database data into Djano (fixtures, postgresql)

Django: Update specific part of template by button click
I have a text field <input type="text" value="This is a test." name="mytextbox" size="10"/> and separated from that a button <button type = "button" class="btn btn-primary"> <font size="1">Run</font> </button> that should update a list and update the value of the text field itself. Sometimes forms are used in this context, but I would have to wrap the forms tag around the whole template when the input and button are separated on the screen. Since I am relatively new to Django, I would like to know the best strategy to solve the problem. a) Reload the complete page template with changed arguments/context b) Create a html template of the specific part that extends the main template and only try to render/update this one. c) Do something smarter. There are some answers in a (much older) post from 8 years ago but I am interested in the state-of-the-art solution. -
