Django Chrome Browser Disable Styling/Scripts On Sitemap.xml and Robots.txt
I noticed in django-csp the sitemap.xml file displays styling and scripts on chrome browsers but firefox displays "This XML file does not appear to have any style information associated with it. The document tree is shown below." Is there a way to programmatically in Django to tell chrome not to process any styling or scripts for the sitemap.xml file or even the robots.txt?

get full User object on post_save signal
I am new to signals. What I want to do could be done on views pragmatically and perhaps signals is not the way to go but regardless, I am having issues with the signal. I have a User model (custom) and UserIdentities model. When a new user is created, 3 identities will be generated and saved in UserIdentities model: User(models.Model): fields... UserIdentities(models.Model): user = models.ForeignKey(User) @receiver(post_save, sender = User) def user_created(sender, instance, created, raw, **kwargs): if created: # generate three dept identities and save in UserIdentities model identities = generate_identiteies(instance) The issue I am having now is that instance is username (a single string), not an instance of User object with all attributes of the user. In the documentation, it says instance is the object that was created but here I am getting only the username of the user created but need a couple of other fields needed for identity generation -

Pass OneToOne relationships to Django Templates
I am trying to setup a OneToOne relationship in Django in order to show data from TableA and TableB for a specific record. I am having issues figuring out how to display it in my view, examples are out there but some seem a bit outdated or have solutions that I am not familiar with. I have tried with some different calls in the views file as well as in my templates file without any luck, any input would be highly appreciated!

What does this html tag mean in django's example?
This is django's polls demo, and most are well documented.

Sending pop-up notification to specific users in Django
I am working on a notification part of a Django project where 1. an user can create a project (selecting users to work with), and 2. create a meeting (the creator can edit or cancel by changing the meeting location or time), and 3. invitees can vote for a preferred time and eventually decide the meeting time where the majority agrees with. My part is to send any types of notification to those invitees when cases 1-3 happen. For example in cases 1 and 2, I wanna implement the way to give invitees pop-up notifications when the creator submits the form, and for case 3, I want invitees to be notified when each invitee votes. class Notification(models.Model): created = models.DateTimeField(auto_add_now=True) text = models.TextField() users = models.ManyToManyField(User, through='NotificationUser') class NotificationUser(models.Model): created = models.DateTimeField(auto_add_now=True) updated = models.DateTimeField(auto_now=True) user = models.ForeignKey(User, on_delete=models.CASCADE) notification = models.ForeignKey(User,on_delete=models.CASCADE) read = models.DateTimeField(null=True, blank=True) I have written models for the notification (feel free to give me advice for better models), but I can’t really think of the best way to send those invitees pop-ups (In view). Even if it’s not a pop-up notification, as long as you have a better or easier idea to implements, please help me! … -

Bootstrap scrollbar slipped behind content
I am working on a webpage using Bootstrap 4 and after fixing the appearance of a horizontal scrollbar on mobile devices by adding overflow-x:hidden to the html tag I noticed that the main y scrollbar looked weird and was not clickable most of the time anymore (normally it can be pulled with the left mouse button, but it does not react to clicks now. It does, however, register clicks on content that is behind the scrollbar!). It has definitely not been like this for long, but I have not the faintest idea what caused this change since I did not touch any z-index or scrollbar settings... I am using Chrome and it should display the standard, unstyled scrollbar, which does not look like this. Can anyone tell me what happened and how to fix it?! -
Dropdown navbar menu on my Django/Bootstrap 4 website works everywhere except on the home page
As the title says, I have a dropdown menu on my site. At first it only worked on the homepage and nowhere else until I realised I didn't include the link to the Bootstrap JavaScript framework in the base.html file. So I included it and now the dropdown menu works everywhere except on the homepage. I feel like this is a simple fix and is just staring me in the face but it has me stumped. Any help is appreciated.

Serve medias as static django

Django Model Form not saving NULL data
I have the following form, view and model form, the Django version is 3.0 and the original DB is written in PostgreSQL, the form is submitted via ajax. class Model(models.Model): depth = models.FloatField(blank=True, null=True) from_field = models.FloatField(blank=True, null=True) to = models.FloatField(blank=True, null=True) interval = models.FloatField(blank=True, null=True) class Meta: managed = False class Form(forms.ModelForm): class Meta: model = Model fields = ['depth', 'from_field', 'to', 'interval'] @csrf_exempt def AddData(request): form = Form(request.POST) if form.is_valid(): form.save() When AddData is executed there is no errors but with the data being something like: depth=30, from_field=null, to=null, interval=null The data saved in the database is: depth=30, from_field=0, to=null, interval=null Could this be because the model has the parameter managed=False? I've checked the data sent by the template and when it's received by the view and the null data reflects correctly in DB except for from field. -
Django filter: Many to Many specific field to custom Group field
This is probably not the best way to go about user permissions- though I have a list of User Groups that contain names of Markets and a custom field built in containing the "Market_id".
