How to properly fork django-taggit?
I want to make a small tweak to django-taggit - I want to add an added_by field on the Tag model as a ForeignKey to User, so I can list all tags added by a particular user. So, I cloned the repo into the folder where all the apps are and made the changes to the code, however I'm getting an error: /home/alex/.repos/codelib/github/hawk/src/hawk/hawk/settings.py changed, reloading.

Django Stripe Fake Card Causes TemplateDoesNotExist Error
When a person types in a fake credit card into my Stripe payment form, I get an error page saying "TemplateDoesNotExist at /memberships/payment/ followed by membership/membership_payment.html". The following lines of code get executed: views.py: https://dpaste.de/8EUX#L77,78,79,80,81,82,83,84,85 html files: https://dpaste.de/2Y37 I need a way to not show that error page and redirect the user back to /memberships/ and display a card decline message instead. However, if a user types in a valid card, that redirect is correct. Otherwise maybe I need a way to validate the card is able to be charged to see if it is a real one before being able to submit the form. Traceback has been included in the dpaste link. I am using this github project as a baseline so all files are mostly the same (except for my dpaste code updates): https://github.com/danialbagheri/video-membership Any help would be greatly appreciated. -

defautl image in the field "ImageField" - Django
I try to put an image in an ImageField by default. But I can't solve the problem. My first attempt at solution was the following: from django.contrib.staticfiles import finders result = finders.find('img/image.png') models.ImageField(upload_to = user_model_custom_upload, default = result) My second attempt at solution was the following: from django.conf import settings import os DEFAULT_AVATAR_PATH = os.path.join(settings.MEDIA_ROOT, 'images/no-avatar.png') models.ImageField(upload_to = user_model_custom_upload, default = DEFAULT_AVATAR_PATH) neither solution worked But something curious happens with the second method, is that at the time that Django searches for the image, the image path for Django is as follows: Not Found: /media/home/lcteen/Documents/Programming/Frameworks/Django/ibme_project/media/images/no-avatar.png I don't know what is currently happening, it's like the structure of my directories is in the media folder or something ... but my media folder doesn't change at all.

HTML5 video elements loading time
I just want to figure out why my website is serving video files without coherence. First of all, I have created my website on ODROID-XU4 and OS is Ubuntu. Also, using Django and Apache2 as Framework Anyway, here is my problem. Videos won’t start instantly when I click the play button But, funny thing is some video files with big size do play instantly. For example, when I upload 3GB of video(mkv) and click play button, it plays instantly. However, another video file which is only 1.8GB uploaded won’t be played before fully loaded. Please, I am waiting for answer from someone who had similar experience -
How do I create a Django admin section for managing content on an individual page, such as homepage?
I would like to allow an admin to edit content sections on a homepage, about page, or contact page. A content section with a changeable background image, or a content section with changeable text. Is there a built-in Django package that addresses this? If not, would you recommend another third-party Django integration? I have searched using similar questions and have found that there are very few related answers. -
Display Foreign Key linked models in Django rest framework
I have three models I would like to display with in a treeview Event Market Runner Runner Runner Market Runner Runner Event can have multiple markets and markets can have multiple runners. I would like to be able to get fetch these models from one api request to view and delete old events if necessary.

Django database tables created under wrong schema
I created a Django application and connected it to SQL Server with a trusted connection. When I migrate, Django is creating a new schema name (trusted connection username) in the database and adding this on all tables as prefix. By my IT department convention, all tables should be created with the 'dbo' prefix. The most interesting part is: When I access the database from SQL management studio (also with trusted connection), and create a new database, I do not have this issue, it creates as 'dbo.table_name'. Does anybody knows how can I fix it? See below better example and some code. Summary: Django is creating: 'my_username.table_name' I need: 'dbo.table_name' My django settigs.py DATABASES = { 'default': { 'ENGINE': 'sql_server.pyodbc', 'NAME': 'dabase_name', 'HOST': 'database_host', 'USER': '', 'OPTIONS': { 'driver': "ODBC Driver 17 for SQL Server", 'Trusted_Connection' : 'Yes', } } } One of my models (table) as example: class Sap_module(models.Model): sap_module = models.CharField(max_length=2, unique=True) available = models.BooleanField(default=True) def __str__(self): return self.sap_module -

Django `get_or_build` similar to `get_or_create`?
I'm curious if there's a way to do something conceptually like a "get_or_build" for an object, without saving it (yet), so you can reference itself to set a field before saving. Similar to Ruby's find_or_create_by or find_or_initialize_by with a block. For instance, given the following model: class User(models.Model): unique_id = models.UUIDField(default=uuid4) first_name = models.CharField() last_name = models.CharField() meta = models.CharField() and an example of creating a User user, created = User.objects.get_or_create(first_name="Jane", last_name="Doe") let's say I wanted to also set the meta column to whatever the default value for unique_id is in this situation, on initialization. I would have to do something like this, since it would be available when initializing the object: user = User.objects.filter(first_name="Jane", last_name="Doe") if not user: user = User(first_name="Jane", last_name="Doe") user.meta = user.unique_id user.save() is there anything like: user, built = User.objects.get_or_build(first_name="Jane", last_name="Doe") if built: user.meta = user.uuid user.save or a way to reference from within get_or_create: user = User.objects.get_or_create(first_name="Jane", last_name="Doe", meta=self.unique_id) -

Why multiple ajax requests in each other do not execute?
I have multiple ajax functions inside each other, but only the first ajax request is executed and I do not know why! I have added some alert fields to see how far it gets. I am using django environment for this. So for example when the bidnow-BTN is clicked this jquery should execute, but for some reason the after the first ajax request the page actually refreshes and adds something like /?bidPrice=100001 to the end of the url of the page. This should not happen. $("#bidnow-BTN").click(function(){ var varurl = document.URL var itemId = varurl.split(/\//)[4] $.ajax({ url : "{% url 'User ID' %} ", method : "GET", success : function (data) { var varurl = document.URL var itemId = varurl.split(/\//)[4] var username = data.username alert("Got here: " + username) $.ajax({ url : "{% url 'Bidding ID' %} ", method : "GET", success : function (data) { alert("Does NOT reach this point") for(var i = 0;i<data.users.length;i++){ if(data.users[i].username==username) { var id = data.users[i].id } else{ } } $.ajax({ // kinda checked url : "{% url 'List Items' %} ", method : "GET", success : function (data) { var varurl = document.URL var itemId = varurl.split(/\//)[4] for (var i = 0 ; i<data.items.length;i++){ if(itemId … -
Calculating fields with filters in Django
I am extremely new to Django and kinda new to python and programming in general, so i may be asking a dumb question. I am trying to track medications in our inventory at work. Here is my model for the inventory in our safe class Safe(models.Model): user = models.ForeignKey(User, on_delete=models.PROTECT) date_created = models.DateTimeField(auto_now=True) drug_name = models.ForeignKey('components.Drug', related_name='drug_remove', on_delete=models.PROTECT, default=0) amount_removed = models.IntegerField(blank=True, null=True) amount_added = models.IntegerField(blank=True, null=True) incident_number = models.CharField(max_length=20, default=0, blank=True) patient_name = models.CharField(max_length=20, default=0, blank=True) medic_unit = models.ForeignKey('components.MedicUnit', related_name='medic_unit', on_delete=models.PROTECT, blank=True) free_text = models.CharField(max_length=1000, default=0, blank =True) drug_total = computed_property.ComputedIntegerField(compute_from='add_drug') I would like to store the medication total for each drug in the database. I understand from researching this that storing totals isn't best practice in most cases but I believe this is one exception. Obviously the calculated integer field isn't the answer, but none of my research has gotten me any closer to the answer. My guess is that I first need to filter by 'drug_name' and then calculate the added or subtracted drugs from the previous total in a function within my model. Thanks ahead of time for any help. -
Changing model field value to True after expiration time
I am in the process of creating a simple car rental project in Django. I have a view in which the user must enter the value for how many days he wants to rent a car and press the "Rent" button. In this situation the "is_car_available" field of the "Car" model gets False value and it is not possible to rent. @login_required def rent(request, pk): car_to_rent = Car.objects.get(pk=pk) if request.method == 'POST': form = RentingForm(request.POST) if form.is_valid(): days = form.cleaned_data['days'] total_price = car_to_rent.car_price * days reservation = Reservation.objects.create(how_many_days=days, car=car_to_rent, booker=request.user, total_price=total_price) car_to_rent.is_car_availible = False car_to_rent.save() content_for_frontend = { 'car_to_rent': car_to_rent, 'form': form, } return render(request, 'rental/rent.html', content_for_frontend) else: return HttpResponseRedirect('/') The Reservation model has the "expiration_date" method, which is calculated after adding the rental date to the number of days. I would like to see "is_car_available" change to True at the end of the rental. Any ideas how to solve it? -

PDF generation not working after upgrading from Django 1.8 to 2.2
After upgrading Django from 1.8 to 2.2, trying to generate a pdf now sends me to a page that says This XML file does not appear to have any style information associated with it.

How to insert an image or video in html?
I have a django page that shows me a video loaded from a directory. I have a form with a drop-down list: <form name="formulario" enctype="multipart/form-data" method="POST" action="" name="formulario"> {% csrf_token %} {{ form.as_p }} <select name="type" id="type"> <option selected>Select the type of file</option> <option>Video</option> <option>Picture</option> <option>Gif</option> </select> <br><br> <input type="submit" class="btn btn-success" value="Upload"/> <a href="{% url 'fileupload:delete' %}" onclick="confirm('Are you sure you want to delete the files?')" class="btn btn-success">Delete Files</a> What I intend to do is that if the drop-down list selects video, I will insert a video and if I select a picture, I will insert an image. For example: {% if valor == video %} <video src='{{videofile.videofile.url}}' width="640" height="480" controls autoplay></video> {% endif %} {% if valor == picture %} <img src='{{videofile.videofile.url}}' width="640" height="480" controls autoplay></video> {% endif %} In the project I have a static folder where the files are stored, either images or videos, so the user searches for the image or video, this is saved in the folder and is displayed on the page. How could I do this? Regards.
