How to fix this 400 bad status error while accessing my pache on apache sever?
I'm deployed my django app on server and when I'm trying to get the page on my web browser, then "Bad Request (400)" is all I can see on the page.

Django:Admin List_display is not working for one specific model
I am building an app. I am trying do display fields for 2 different model. Consultation and Consultationserie. The list_display function works for consultationserie but not for consultation. It only shows one field (start_date). There is a foriegnkey of linking to a consultationserie type in the consultation model. I wonder if it is causing a problem. I added to create a parent to child relationship between consultationserie and consultation. Thank you in advance for your help I tried to use different register method (With the decorator, with admin.site.register, admin.site.register(Consultation,ConsultationAdmmin)).

How to divide my app and make extensions?
So, a while ago i have made a web application and now i want to improve it and put some premium content. The problem is that i have no idea how to do that. The application is used by different roles(for example: students, professors, administrators, etc.) and i want to make a normal package, premium package and custom package that i will sell optionally. Normal package would contain only base functionalities, premium would contain all of them and custom would contain only functionalities that customer wants. Imagine it like this, the application is made for an University and a professor is using it. There is an index page for his role and if he is using a normal package he can see only timetable of his lessons, if he is using a premium package than he can see his timetable, students who go to his class, grades, etc. How can i achieve that? Do i need to make numerous versions of an applications for every combination of functionalities? I hope there is a way to achieve this by separating functionalities and somehow disabling and enabling them optionally. P.S. I am using Django framework for backend and React js for frontend. -
Bidirectional OneToOne relation - Django
I have two models (Slot, Appointment). On the appointment one, I have defined a OneToOne relation with the slot model, so good so far; thanks to the RelatedManager I can access the appointment from the slot object but this's done at python level and I need (for some future changes) appointment_id column to be created on the Slot table. class Slot(models.Model): start_at = models.DateTimeField() end_at = models.DateTimeField() duration = DateTimeRangeField( null=True, blank=True ) # Bidirectional appointment = models.OneToOneField( "appointments.Appointment", on_delete=models.SET_NULL, related_name="slot", blank=True, null=True ) class Appointment(models.Model): slot = models.OneToOneField( Slot, on_delete=models.SET_NULL, related_name="appointment", null=True, blank=True, ) The code above will raise some errors when trying to create the migrations like: appointments.Appointment.slot: (fields.E302) Reverse accessor for 'Appointment.slot' clashes with field name 'Slot.appointment'. HINT: Rename field 'Slot.appointment', or add/change a related_name argument to the definition for field 'Appointment.slot'. Basically, due to the python part of the ORM, you can't define the same field on both models. Any idea of how to achieve this. I guess I will have to overwrite some parts of the RelatedManager. I could make this throw SQL but then it won't be clear on the code level. -
How to send object from django template to view function?
I want to send objects from a list in django template to view function. Basically what I want to do is that whenever user hits "view" button in code then I send a post request and send "sel" as data to a view function because I have to use "sel" in view function. search.html {% for sel in selections %} <div class="col-md-4"> <div class="card mb-4 shadow-sm"> <img src="../static/listhome/media/images/house2.jpg" width="100%" height="225" preserveAspectRatio="xMidYMid slice" focusable="false" role="img" ><rect width="100%" height="100%" fill="#55595c"/></svg> <div class="card-body"> <h3>Price: </h3> <p> {{sel.address}}<br> Bedrooms: <br> Baths: <br> Square Feet: {{sel.approximate_square_footage}} </p> <div class="d-flex justify-content-between align-items-center"> <div class="btn-group"> ## THIS IS BUTTON TO BE USE TO SEND DATA <button type="submit" class="btn btn-sm btn-outline-secondary">View</button> </div> <small class="text-muted">Days listed: </small> </div> </div> </div> </div> {% endfor %} 'Selections' is a list containing some elements from my database.

Django Registration and Login on Same Index Page
I'm trying to have a registration and login form both on my index page (NOT separate login/register urls). I'm able to display the forms, but having trouble with submission.

Overriding an UpdateView's get_form_kwargs() method

Django Foreign key field validation in a forms or models ( getting info created by only that user from foreign key)

Wagtail - Revisions for Non-Page Objects
I use vanilla django models (they do not inherit from Page) and the modeladmin module of wagtail to replace the standard django admin with the wagtail admin interface. This is all working great, but I now wish to add revision history and rollback to these models. Wagtail of course has it's own system for managing revisions of objects that inherit from Page, but they would not apply to standard django models. On the other hand, I have been looking at using the django-revisions app to have this functionality. Although this works, django-revisions only provides a standard django admin view, which is not compatible with wagtail, and I would prefer to not have users switching between the two completely different looking admin areas. Does anybody have experience with managing revisions and rollbacks of standard model instances within the context of wagtail? -
Django message is not cleared on web-page reload, causing previous pop up to redisplay
I have a web-page that shows a contact-form. Details are entered and using this an email is sent. To indicate success of sending the email I used Django messages framework, which adds a message with text content 'success'. The html-template checks 'messages' list in a for loop and if met with a message with content 'success', defines a div that contains an ok button (to click and remove this div). I could not find a way to get a JS alert pop up box to trigger after comparison met, so this is why Im defining an absolute position div box myself. I have managed to get the pop up to be removed on click on 'OK', and to bring a new pop up on sending new email, but after I have cleared the pop up and then reload the page, the pop up returns. I suspect the message list containing 'success' message from previous form submit persists on the new page and template has matched it with its condition again. I've tried to use body tag onload to trigger a JS function to clear 'messages' but nothing happened. Not sure 'messages' can be accessed. Tried putting some code found online … -

Create a new app in a Django project with multiple databases
I currently have a PostgreSQL database setup using Django which contains a bunch of loans and different attributes. I am now looking to grab a subset of these loans, perform some operations (randomize attributes using a distribution), and load these into a separate database. I am also looking to keep a mapping of the original loans to their new counter parts, should I be creating a new app in my project or starting a new project? I have been looking into using multiple databases as I don't see a way around this and have started with a new app in my current project but am stuck on creating the mapping and choosing which database to select data from and which one to write the updated data to. I'm fairly new to Django and the original database and Django files were created by another person, any help or advice is greatly appreciated. -
