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... Any hints? -
After scheduling a new task, previously scheduled tasks are not getting executed by Celery Beat (Django)

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. I tried using JsonResponce, but no success: def card(request): cur_rk = 0 if request.method == 'GET': if request.GET.get('C', '') == '-1': q1 = "SELECT MAX(RK) AS L_RK FROM B_DATA;" with connection.cursor() as cursor: cursor.execute(q1) val = cursor.fetchall() cur_rk = val[0][0] return render(request, "card.html", get_db_data(cur_rk)) return render(request, "card.html", get_db_data(cur_rk)) Here is the html code if it might help you: <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Create new card</title> </head> <body> <div class = "enter_data"> <form action = "" method="POST">{% csrf_token %} <div class = "base"> <h2>Базови данни</h2> <input type="number" class="field" placeholder="Enter RK" value = {{RK}} name="RK"> <input type="text" class="field" placeholder="Enter RN" value = {{RN}} name="RN"> <input type="text" class="field" placeholder="Enter Marka" value = {{Marka}} name="Marka"> <input type="text" class="field" placeholder="Enter … -
Django: Problem rendering and downloading HTML in PDF format, styles and resources are not applied correctly

How to create a custom UI for admin interface in Django
Okay, I probably couldn't explain the issue in the title very well but I am building a Django app which will have various contributors. These contributors will not have superuser privileges but only some read/write privileges. Right now, I have a custom AdminSite which can be accessed by the Contributors. Here's the code: admin.py class ContributorAdmin(AdminSite): def has_permission(self, request): return request.user.is_active urls.py urlpatterns = [ path('admin/', admin.site.urls), path('contributor/', contrib_admin_site.urls), path('login/', loginview, name='login'), path('logout/', logoutview, name='logout'), #other paths for the app ] This is working as intended and gives the contributors access to the admin interface with limited privileges. However, what I would like to do is create a custom Admin UI (not the built-in Django one) which will be used by the Contributors. As an example, I would like to have a contributor.html in my templates which provides Admin like interface to the contributors but the styling etc. is all customized. Also, I would like to have my login and logout views to redirect to this custom page only. Right now, the login page redirects to ContributorAdmin so my custom logout view becomes useless. Is it possible to do this? Thanks in advance! -
Can I use hash partitioning on a non-primary key column in a PostgreSQL table?
I am trying to replace an existing table with a partitioned version of that table. I want the schema of the new partitioned table to exactly match the existing non-partitioned table so that I can continue to manage the table through Django migrations. My first attempt at creating the new partitioned table looked something like this: CREATE TABLE partition_test ( row_index bigint, id character varying(128) PRIMARY KEY, vendor_id character varying(128) ) PARTITION BY HASH (vendor_id); Which results in the following error: ERROR: unique constraint on partitioned table must include all partitioning columns DETAIL: PRIMARY KEY constraint on table "product_api_partition_test" lacks column "vendor_id" which is part of the partition key. I am looking for a work around that will allow me to partition on vendor_id while keeping row_index as the primary key. I tried modifying the primary key as follows, however, Django requires a primary key and does not support composite primary keys. Therefore, both of these options would result in an inconsistency between the true schema and what Django believes is the schema. CREATE TABLE partition_test ( row_index bigint, id character varying(128), vendor_id character varying(128) PRIMARY KEY (row_index, vendor_id) ) PARTITION BY HASH (vendor_id); CREATE TABLE api_partition_test ( row_index bigint, … -
