Saving data from a dynamically generated HTML table/grid to a database
I'm developing a web application and one of the requirements is for the user to enter data into a dynamically-generated HTML grid/table. An admin user can log into the Django Admin interface and create some entries which will represent the columns and rows of the grid, and then a dynamic grid is genereted based on these values. In this example, the admin user has entered "Store #1", Store #2", etc as the rows, and "Chips", "Chocolates", and "Soda" as the columns. These rows and columns are then used to generate a grid which is rendered in a Django template by the code below: <table class="tg"> <thead> <th rowspan="3"></th> <tr> <td class="tg-title" colspan="4">Inventory</td> </tr> <tr> {% for i in items %} <td class="tg-column">{{ i }}</td> {% endfor %} </tr> </thead> <tbody> {% for i in stores %} <tr> <td class="tg-column">{{ i }}</td> {% for i in items %} <td class="tg-cell"><input type="number" min="0" max="255" value="0"></td> {% endfor %} </tr> {% endfor %} <tr> <td class="tg-totals">Totals</td> {% for i in items %} <td class="tg-totals-values">0</td> {% endfor %} </tr> </tbody> </table> The above code renders like this: rendered_image Visually, this is fine, but I can't for the life of me figure out how I'm … -
When click a link in a link list generated by for loop, make the corresponding checkbox checked instead of the first checkbox
I have used Django to develop a web app. The front end used Django template engine. In the HTML, a link list is generated by a for loop, before which a check box is shown corresponding to this link. I want to achieve this: when click the link, the corresponding checkbox would be checked. But now as I only has one id(in the loop I do not know how to generate different id in one line), o matter I click which link generated by the loop, always see the first checked box checked instead of the corresponding one. HTML: <td>{% for course_for_select in query_results_2 %} &nbsp;<input type="checkbox" name="course_select" value=" {{course_for_select}}" id="addModal-body">&nbsp;<a href="#" name="course_select_2" id="href_course" onclick="document.getElementById('addModal-body').checked = true;this.closest('form').submit();return false;">&nbsp; {{course_for_select}}</a><br> {% endfor %}</td> How to let the corresponding checkbox checked after click the link behind, instead of constantly see the first one being checked? -

Django- how to hyphenate TextField in URLs
I am trying to make my model so that the URL slug is hyphenated between spaces in the slug field by default. The slug should be limited to only the first six words in TextField. The TextField() called questionToProblem in the same model. Here's what I have: class Problem(models.Model): free = models.CharField(max_length = 1, choices = Free) questionToProblem = models.TextField() solutionToProblem = models.TextField() slug = models.CharField(max_length = 250, unique = True) topic = models.ForeignKey(Topic, on_delete = models.CASCADE) plainText = models.TextField(default= 'temp') class Meta: ordering = ('questionToProblem',) def get_url(self): return reverse('solution_details', args = [self.topic.slug, self.slug]) def __str__(self): return self.questionToProblem Ideally, here's what I want the URL to look like, if the questionToProblem was "How many bananas do I have in total?", and the Topic key was "modeltopic": http://127.0.0.1:8000/modeltopic/How-many-bananas-do-I-have -
I want to keep a long process running in the background in django
I am a beginner in django. I want to keep running long processes in django in the background. And I want to keep it running unless I explicitly end that process. I can't figure out where and how to add the following code to django. import threading import asyncio class long_task: def __init__(self): self.continue_flag = True async def long_task(self,): print('long task start...') i = 0 while self.continue_flag: print(i) await asyncio.sleep(3) i = i+1 def stop(self): self.continue_flag = False def run_loop(loop): asyncio.set_event_loop(loop) print('main loop start...') loop.run_forever() def ask_loop_stop(loop): print("main loop stop") loop.call_soon_threadsafe(loop.stop) loop = asyncio.get_event_loop() threading.Thread(target=run_loop, args=(loop,)).start() print('main loop is ready') long_task_1 = long_task() asyncio.run_coroutine_threadsafe(long_task_1.long_task(), loop) I will elaborate on what I want to do. Run a loop when django starts. Add long_task to the loop at any given time (when a specific event occurs by monitoring an external site). Keep the program running in the background so that the site can be viewed. In the future I would like to display the results of this program on a page. Close the loop at another time (during maintenance). Here's what I've tried Register and execute as a task using celery and celery-beat. => Can't specify that a program should be run … -

DRF get_queryset check if in ManyToManyField
I have a model like this: class Project(models.Model): name = models.CharField("Name", max_length=8, unique=True) status = models.CharField( "Status", max_length=1, choices=[("O", "Open"), ("C", "Closed")], default="O", ) description = models.CharField("Description", max_length=3000, default="") owner = models.ForeignKey( User, on_delete=models.SET_NULL, null=True, related_name="project_owner" ) participants = models.ManyToManyField(User, related_name="project_participants", blank=True) created_at = models.DateTimeField(auto_now_add=True) Now in this model's ViewSet I have a get_queryset method: def get_queryset(self): if self.request.user.is_superuser: return Project.objects.all() else: return Project.objects.filter(owner=self.request.user.id) So when I get a project or projects, I only search for the projects that a user (hidden in the request, in JWT) owns. But now I thought about searching for the projects that user participates in (so the user appears in participants field list). How can I do that in get_queryset? -
How do I customize the Django "Password_reset_confirm" form?
I need to modify the labels and give a max_length to the django form for restoring password (The one after clicking on an email link to restore the password). I have done it for AuthenticationForm, UserCreationForm, UserChangeForm and PasswordChangeForm so far but i don't get to find a way to do it for the Password_reset_confirm Form. This example for the AuthenticationForm shows how I'm overriding all the forms. Forms.py from django.contrib.auth.forms import AuthenticationForm class loginForm(AuthenticationForm): username = forms.CharField(widget=forms.TextInput(), max_length=64) password = forms.CharField(widget=forms.PasswordInput(), max_length=64) class Meta: model = User fields = ( "username", "password" ) -
How to use a Django modelformset with extra fields?
Here is the example of an inline formset from Django's docs: from django.db import models class Author(models.Model): name = models.CharField(max_length=100) class Book(models.Model): author = models.ForeignKey(Author, on_delete=models.CASCADE) title = models.CharField(max_length=100) >>> from django.forms import inlineformset_factory >>> BookFormSet = inlineformset_factory(Author, Book, fields=('title',)) >>> author = Author.objects.get(name='Mike Royko') >>> formset = BookFormSet(instance=author) Suppose I want to let someone enter multiple book reviews at once, where each book review is for a particular book. (I'll have a query in my code to get the books to review.) How do I display a formset (model formset? inline formset?) of BookReview, but with some of the book data (e.g., title) on the form, so people know which book they are reviewing? So, the model is class BookReview(models.Model): book = models.ForeignKey(Book, on_delete=models.CASCADE) review_text = models.CharField(max_length=1000) Now how to initialize the formset? Below is some code, but based on my actual example (not book reviews), it's not going well. Sample code to initialize a formset (but incomplete): # pick some books to review # this could change, I don't want to couple it directly to the formset books_to_review = Book.objects.filter(author=an_author)[:3] class BookReviewForm(models.ModelForm): class Meta: model = BookReview fields = ('review_text') # How do I get Book.title (and possibly … -
Django EmalField form input is always set to active
so I have this form as on this image below. The point is that if the user clicks any of the fields, the text (which is essentialy a label, not a placeholder) rises up which shows that the clicked input field is active. However, I've tried to create a customized user creation in Django, which is just to have the email as the main user identificator, not the username. Now everything else works as supposed, but the thing is that the email field always appears as active (you know, the css attribute). I will now paste a scary amount of code and I will be happy if you could find out what's wrong. Sorry for the trouble `class UserManager(BaseUserManager): # handles user creation, havent' tested yet def create_user(self, email, username, password=None): # creates user with email as their id if not email: raise ValueError('Users must have an email address') if not username: raise ValueError('Users must have an username') if not password: raise ValueError('Users must have a password') user = self.model( email=self.normalize_email(email), password=password, username=username, ) user.set_password(password) user.save(user=self._db) return user class User(AbstractBaseUser): # user model, was just trying out some stuff username = models.CharField(verbose_name='username', max_length=30) email = models.EmailField(verbose_name='email', unique=True, max_length=60) date_joined = … -
In my PayPal server side integration, the payment popup immediately closes. How do I fix this?
I'm trying to setup paypal server side integration, but I keep stumbling on what is likely a very simple issue. The paypal payment browser window briefly appears to be loading, but it closes before I can do anything; it doesn't reach the login page or anything. In my django logs, I don't see any errors. Similarly, nothing stands out to me when I search the network activity. If I use a direct link to the paypal authorization page, I don't have any issues. Views.py def setUpAuthorization(request, max_price = 100): environment = SandboxEnvironment(client_id = settings.PAYPAL_CLIENT_ID , client_secret = settings.PAYPAL_CLIENT_SECRET) client = PayPalHttpClient(environment) # get_item request = OrdersCreateRequest() # Make initial authorization request.request_body( { "intent": "AUTHORIZE", "application_context": { "return_url": "https://www.example.com", "cancel_url": "https://www.examples.com", }, "purchase_units":[ { "description": "DESCRIPTION", "amount": { "currency_code": "USD", "value": max_price, }, } ]} ) response = client.execute(request) data = response.result.__dict__['_dict'] links = data['links'] for link in links: if link['rel'] == 'approve': paypal_link = link['href'] # redirect(paypal_link) return JsonResponse(data) html <div id="paypal-button-container"></div> <script src="https://www.paypal.com/sdk/js?client-id={{client_id}}"> </script> <script> var CSRF_TOKEN = '{{ csrf_token }}'; </script> <script> function getCookie(name) { let cookieValue = null; if (document.cookie && document.cookie !== '') { const cookies = document.cookie.split(';'); for (let i = 0; i < cookies.length; … -
How to load an online JS file in a webpage in Django Application

Django send user an email with a user link for setting a password
I'm a newbie to Django and I'm learning from its documentation. In my Django app, I'm attempting to have the admin create the users and once they have been created, I would like them to be sent an email that contains a link that enables the user to set up their own password for logging in.

Please be patient and don't create any closing votes as I want a definite answer with this question. Thanks in advance. -
How do I optimize this Django query that uses an annotated Subquery?
I have an approval queue Django app that has two models: Flow and Recipient. The Flow keeps track of each "request" in the approval queue system, and the Recipient tracks who can approve each step in the queue, and can be related to a Django User or Group. Here's a simplified snippet of what these models look like: class Flow(models.Model): current_step = models.IntegerField(default=0) class Recipient(models.Model): step = models.IntegerField() user = models.ForeignKey( User, on_delete=models.PROTECT, null=True, blank=True) name = models.CharField(max_length=255) flow = models.ForeignKey( Flow, on_delete=models.PROTECT, related_name='recipients' If an approval queue has 3 people (recipients) in it, each Recipient's step will represent its position in the queue. The first person's Recipient will have step == 0, the next person will have a step == 1, and so on. The Flow.current_step is updated when the approval queue progresses from one person to another. My goal is to query for Recipients, and include an annotated field named assigned_to which will contain either User.first_name or the name of the Recipient of the "current" Recipient. The current Recipient is the one whose Recipient.step == Flow.current_step. All Recipients will either have user or name set. Here's my first attempt at implementing this query: current_rec = Recipient.objects.filter(flow=OuterRef('flow'), step=OuterRef('flow__current_step')).select_related('user') qs … -

Should I be using Celery/Redis in my Django application?
I have a Django application that is designed to be used as a companion tool for sportsbooks or DFS sites. I am largely self-taught, so I have been adopting a more "go with what works" approach and then going back to revise my methods as I learn better ways to create the app. I have several tables from scraped data in CSV format that I import into my DB with shell scripts. For example, one table is for starting lineups, and another is for player stats. I then have methods set up in my models.py to take that imported data and turn it into data that I want to use. I found out quickly that trying to call a large group of objects and the values from their method functions was not at all efficient. I get the data I need via the methods because a lot of it is based on data from multiple tables (for example, I might want the start time of a game from the starting lineups table for a player object.) The current solution that I have is to use Threading to run a function every few minutes to calculate the results of every method … -
Is there a way to hot build react to use with Django?

The problem of getting an object created thanks to TabularInline
My model A uses TabularInline, which creates objects of model A1. I want to output information about object A1 to the console when I save object A. I use the clean/save method. When I save an existing A object, it's fine, but if I create one, it outputs an error. How can I track the creation of object A1 in object A? Thank you. class A(models.Model): name = models.CharField(max_length=120) def save(self, *args, **kwargs): super().save(*args, **kwargs) print(self.a_name.all()) class A1(models.Model): description = models.CharField(max_length=120) name = models.ForeignKey(A, on_delete=models.CASCADE, related_name="a_name") error: 'A' object has no attribute 'a_name' It's like the A object is saved first, and only then the A1 objects are created and substituted into A. I think that's how it works, that's why I can't access -
Get all parameters and their values in a request in Django
I have a get request being sent to my Django project with a list of parameters. GET /site/login? _name=bill&_last_name=Smith&_favorite_food=wings I need to get each parameter and it's value. What would be the best way to do this? I know that in Django you can do print(request.data) but I need the parameters.
