My new staging slot cannot connect to a github workflow
I just upgraded my azure web application so that I can have additional deployment slots. I want to be able to push updates from my github to the azure staging slot of my web app so that i can confirm my changes are functioning and loaded before "swapping" it to the my production slot where my domain is active. I can setup continuous deployment on my production slot but when i try to set it up under my staging slot it always gives me errors telling me my resource is not found in github actions. Does anyone have feedback or experience on this? -

How to Assign Existing Contacts to a Task Using Postman in Django Rest Framework Without Duplicating Email
I am currently working on a project using Django Rest Framework and Postman. My objective is to assign existing contacts to a task. However, when I make a POST request via Postman, I receive the error: "contact with this email already exists" The email field in my Contact model is defined as models.EmailField(unique=True), as I need to ensure that each email is unique across all contacts. When I attempt to assign an existing contact to a task using a POST request, I receive the aforementioned error.

Issue with Toggling between New Themes
I'm encountering an issue with a custom Theme Installation in my Django project using v. 4.2.13 and Python v. 3.9.7. In the default Admin side, there is a Moon icon for toggling the Themes (i.e. b/w Light and Dark and Auto). I want to add a Grey theme as my default with a new icon. So there are total 4 icons for themes now - Grey, Light , Dark & Auto. For implementing this, I added a new icon for the Grey theme and the icon is now not visible in the Admin panel (only the default 3 are shown) and the toggling between themes is not working. Below are the screenshots of the code for installing themes with their respective icons. Please also note my teammate has been working on Django 5.0 for making his previous project commits in Github. We wanted to test what can happen to the same functionality if team members work on different versions since we're assuming Git essentially stores all files as basic text files with version control. I am not sure if this has anything to do with my problem. Kindly help. Screenshot 1 - The Admin panel moon icon for theme toggle … -
Globally JSON-serializing UUIDs and other types with psycopg2 and django
I'm developing an application with Django 4.2.10. I am running a postgres database and use psycopg2. In my application, I am working with nested dictionaries (coming out of Django ninja/pydantic schemas) and I would like to write these to JSONField django fields. However, they contain UUID's which results in the following error: TypeError: Object of type UUID is not JSON serializable To resolve this problem, I really prefer a "global" hook/adapter that convinces psycopg2 to properly serialize UUID's and other types so that I don't have to worry about it in all the places where I write this data into the database. It should work for direct/raw queries but also via the Django ORM. I found this JSON Adaptation section in the psycopg2 docs. Note You can use register_adapter() to adapt any Python dictionary to JSON, either registering Json or any subclass or factory creating a compatible adapter: psycopg2.extensions.register_adapter(dict, psycopg2.extras.Json) This setting is global though, so it is not compatible with similar adapters such as the one registered by register_hstore(). Any other object supported by JSON can be registered the same way, but this will clobber the default adaptation rule, so be careful to unwanted side effects. So my thought … -
Session Timeout on User side in Django
I am trying add a session timeout in my Django project by using Django's in-built session middleware. I have implemented session timeout on my project using the Views method I have come across for this purpose and it is working on my Admin side, but in my User side, the redirection that I given not working (i.e. I need to log out the user and get back to the signin page after session expires). My django version : 5.0.2 My python version: 3.12.2 Now it is taking the time and that page will expire but it will not redirect to the signin page. How can I solve this issue? What are some other approaches we can use for implementing Sessions on Admin & User sides both redirecting to the Signup page and persisting the last page worked on upon logging back in ?settings.pymiddilewareViews.pyurls.py -

Problem when trying to generate PDF files within Django with libreoffice
I have a Django application based on the 3.10.11-alpine3.16 image that runs in docker container. When I check during the build if a sample PDF is generated, this will succeed, and I see that when running with root it is okay. The problem is that when I try to issue the same command in the running container's terminal, I got an error and I don't know why. In my dockerfile I have the commands to isntall the libreoffice: RUN apk add --no-cache xmlsec xmlsec-dev libreoffice libreoffice-writer libreoffice-calc libreoffice-impress libreoffice-base ttf-dejavu unzip wget curl openjdk11-jre This commands runs perfectly during build in the name of the root user: RUN soffice --headless --convert-to pdf --outdir /vol/logs /vol/logs/word_sample_01.docx If I try to run the same command when I logged into the docker's terminal, so for example: /usr/bin/soffice --headless --convert-to pdf --outdir /vol/logs/t/ /vol/logs/word_sample_01.docx I get this error: "Unspecified Application Error" I assume it is related to some permissions, but I can't figure it out which one is missing...

How to integrate different user types in djando UserModel?
I have a question regarding the user model in django. My project is to realize an area management system. The following entities have already been modeled: Building Area Area equipment (e.g. which furniture etc) SpaceUser (assignment between space and user) SpaceRequirement (request from a user) Users (those who were, are and will be on the space) Supervisor (user who is responsible for certain areas or buildings) TypeOfUse (e.g. office, laboratory, etc.) Organization (organizational affiliation to team/department etc) Landlord As a special case, the management of workshop spaces that are to be bookable at short notice is managed in the following entities: WorkshopSpace (space x in building y) WorkshopSpaceRequirement (request from a user) The attributes of the entities are: Supervisor firstname = models.CharField(max_length=100) lastname = models.CharField(max_length=100) organisation = models.ForeignKey('Organization', verbose_name='Organization', on_delete=models.CASCADE) email = models.EmailField(verbose_name='Email') phone_number = models.CharField(max_length=20) Users: organisation = models.ForeignKey('Organization', verbose_name='Organization', on_delete=models.CASCADE) firstname = models.CharField(max_length=100) lastname = models.CharField(max_length=100) mgmt_level = models.CharField(max_length=10, choices=CATEGORY_CHOICES, default=E4, verbose_name='Level') cost_center = models.CharField(max_length=50, blank=True) number_employees = models.IntegerField(default=0, verbose_name='Number of employees') number_workstations = models.IntegerField(default=0, verbose_name='Number of workstations') superior = models.ForeignKey('self', on_delete=models.SET_NULL, null=True, blank=True) comment = models.TextField(blank=True) Unfortunately, I made the mistake of implementing the models without taking the django user model into account.

Removing {{ choice.tag }} in Django Template Breaks JavaScript Update Function for Radio Button Selection
In my Django application, I have a form with radio buttons for selecting the number of meals per week. The form also includes checkboxes for meal preferences. I have initialized a preselected value for these fields in my form. I use JavaScript to dynamically update a summary section based on preselected selections when page loads. The radio buttons for meals_per_week are generated by Django and included in the HTML template. If I remove {{ choice.tag }}, the updateSummary function no longer receives the selected value for meals_per_week. How can I fix this issue while still removing {{ choice.tag }}? Here is the relevant part of my HTML template: {% for choice in form.meals_per_week %} <div class="flex-fill mx-1"> <div class="card mb-4 custom-card" data-input-id="{{ choice.id_for_label }}"> <div class="card-body text-center"> <input type="radio" class="hidden-input" id="{{ choice.id_for_label }}" name="{{ choice.name }}" value="{{ choice.choice_value }}" {% if choice.is_checked %}checked{% endif %}> {{ choice.tag }} <label class="form-check-label d-block" for="{{ choice.id_for_label }}"> {{ choice.choice_label }} </label> </div> </div> </div> {% endfor %} And here is my JavaScript function that updates the summary: async function updateSummary() { const mealsPerWeek = **parseInt(document.querySelector('input[name="meals_per_week"]:checked').value);** const mealPreferences = Array.from(document.querySelectorAll('input[name="meal_preference_type"]:checked')).map(el => el.value); let response = await fetch(`/get_price?meals_per_week=${mealsPerWeek}`); let data = await response.json(); const pricePerServing … -

Django GET request a page with a button
I have a django view with html template with a form and a few buttons. When one of the buttons is pressed it sends a get request with a query param and depending on this param I render the page again but with different json paramethers. However I can't return the webpage with a second return. This is the important code of the view for the question. I also tried this without return, but it doesn't work either.
