Detect when user register/Login on Context Proccessor Django
I have to do some checks all the time with the context proccessor.The value must be 'True' as soon as the user logs in.But when navigating the site after logging in, the value should be 'False'. So it should be a one-time True result.I need to do this both for the login process and when registering.And I have to implement them with Context Proccessor in Django. How can I do that? def user_info(request): ctx = dict() user = request.user ... ctx["isRegistered"] = False ctx["isLoggedIn"] = False # if user register website, that moment 'request' : # ctx["isRegistered"] = True return ctx -
understanding try except python/django
I need your help with understanding try-except python/Django. so I have this function: def submit_dept_head_application(request, application_id): cv = request.FILES['cv'] letter = request.FILES['letter'] candidate_id = request.data['candidateId'] rank_id = request.data['requestedRankId'] application_state = { 'candidate_id': candidate_id, 'rank_id': rank_id, 'cv_filename': cv.name, 'letter_filename': letter.name, } creator = Profile.objects.get(user=request.user.id) department = creator.department applicant = Profile.objects.get(user=candidate_id) applicant_profile_id = applicant.id rank = Rank.objects.get(id=rank_id) try: application = Application.objects.get(id=application_id) # TODO - update application except Application.DoesNotExist: application = None if application is None: application = Application(creator=creator, applicant=applicant, desired_rank=rank, application_state=application_state, department=department ) application.save() create_application_directory(application.id) ApplicationStep.objects.update_or_create( application=application, step_name=Step.STEP_1, defaults={'can_update': True, 'can_cancel': True, 'currentStep': True} ) copy_to_application_directory(cv, application.id) copy_to_application_directory(letter, application.id) send_email(settings.SENDGRID_SENDER, ['xxxxxx@gmail.com'], 'new application submitted', 'new application submitted') return Response(application.id, status=status.HTTP_200_OK) right now what is happening is that if there is no open application I create a new one. what I'm trying to do is to add another check, which is Application.objects.filter(applicant=applicant_profile_id) so if I have an opened application for this candidate it won't get to the application.save() but it will send an error. i don't really know how to do so and that's where i need your help please :) -

DJANGO custom import CSV
I have a model with multiple fields. I want to make an importer (possibly with the django import-export library) that only takes two fields and with that calculates the rest of the fields that the model has. I wanted to listen and ask if you know of ways to do this. Since the documentation does not mention much. Thank you all! -
Django project located out of Apache ServerRoot
Got some problems trying to include Django-app in my already configured httpd2 apache server. I'd successfully installed mod_wsgi and set some configuration using the deployment manual: https://docs.djangoproject.com/en/4.0/howto/deployment/wsgi/modwsgi/ I added the following settings in httpd.conf WSGIScriptAlias /djangosrv/ /app/djangosrv/djangosrv/wsgi.py WSGIPythonPath /app/djangosrv <Directory /app/djangosrv/djangosrv> <Files wsgi.py> Require all granted </Files> </Directory> The project has the following structure and runs the only app named 'searchpage' /app/djangosrv -- djangosrv -- searchpage The URLs defined in /app/djangosrv/djangosrv/urls.py : urlpatterns = [ path('searchpage/', include('searchpage.urls')), path('admin/', admin.site.urls) ] When I try to open http://localhost/djangosrv/ I get 404: Page not found (404) Request Method: GET Request URL: http://localhost/djangosrv/ Using the URLconf defined in djangosrv.urls, Django tried these URL patterns, in this order: searchpage/ admin/ The empty path didn't match any of these. And when I try to access http://localhost/djangosrv/searchpage/ I get: Forbidden You don't have permission to access this resource. How can I configure routing in Django-project to make it work with non-server-root URLs ? Should I use some extra directory settings in httpd.conf and configure mod_rewrite ?

Django Authentification with class based views login() method
as I am trying to build a login/registration form, I came into a problem. I am building my form with class based views, and I want to use the login() method for the auth.

How to force a page-break on weasyprint?
I wonder if its possible to create a force break that splits the table rows? I think weasyprint does this in a sense but I want to break the rows in to specific counts (e.g 6 rows per page). Is that possible? I tried something like this: <table> <tr> <th>Header1</th> <th>Header2</th> </tr> {% for d in data %} {% if forloop.counter == 6 %} <p style="page-break-before: always;"></p> {% endif %} <tr> <td>{{ d.name }}</td> <td>{{ d.age }}</td> </tr> {% endfor %} </table> but it just break each row in different pages. Any help would be appreciated. -
Can I somehow combine columns into array of objects (list of dicts) by Django ORM?
I use PostgreSQL as a DB. And I have the following situation: Say, we have the following data (we got it joining two tables - orgs and markers). What I want to get by SELECT is Using raw SQL I would do something like this SELECT orgs.org_id, json_agg( json_build_object( 'id', markers.marker_id, 'name', markers.name ) ) as markers_data FROM orgs INNER JOIN markers ON orgs.org_id = markers.org_id GROUP BY orgs.org_id; But I want to combine those columns this way using Django ORM. Is it possible to do on SQL level not Python? So I don't have to just extract data from the DB and modify it to a desired format on Python level. -
How do I remove unused CSS when using Django, Sass and a frontend framework?
I am using a SCSS-based frontend framework (namely cirrus-ui) with my Django project. For compiling the CSS stylesheet with Sass, I use webpack to compile the static files (Presently only CSS stylesheets but I'm sure some JavaScript will probably work its way in there eventually). In the Python project, I use django-webpack-loader. My compiled, minified CSS stylesheet is a whopping 265 KiB. This is not ideal. I know about PurgeCSS and uncss. While I have not used them before, I think I understand how to call these from the webpack.config.js. What I don't know is how to utilize these or something similar with Django and its templates. Notes: I use Yarn to manage packages. main.scss (example excerpt). @use "cirrus-ui/src/cirrus-all" as *; I actually do provide a custom configuration map, but I don't see how that's relevant to the question. Relevant Django Configuration Details (settings.py) WEBPACK_LOADER = { 'DEFAULT': { 'CACHE': not DEBUG, 'STATS_FILE': BASE_DIR / 'frontend/webpack-stats.json', 'POLL_INTERVAL': 0.1, 'IGNORE': [r'.*\.hot-update.js', r'.*\.map'], } } STATICFILES_DIRS = [ './frontend/static', ] Project layout PROJECT ROOT/ - djangoproject/ - settings.py - templates (TEMP)/ - manage.py - frontend/ - .yarn/ - static/ - (Compiled Static Files Here) - assets/scss/main.css - webpack.config.js - webpack-stats.json - package.json … -
how to link a div using <a href> to appear in the middle of the screen instead of top?
this is to go back to home page that has a listview of posts and to keep the screen at where the post is located after clicking go back button in the post details page. <a href="/users/home#post{{ post.id }}"><button class="button" style="float: right; margin-right: 5px;">Go back</button><br></a> However, since there is a sticky nav bar at the top, it covers the post after clicking go back button.

DRF ModelSerializer meta extra_kwargs not working for related fields
I am designing API in DRF and have stumbled upon one issue that hopefully you can help me to solve. Let's assume I have the following model and a serializer: class SomeModel(models.Model): property = models.ForeignKey( Property, on_delete=models.PROTECT, ) name = models.CharField() address = models.OneToOneField(null=True, blank=True) ...more class SomeModelSerializer(serializer.ModelSerializer): class Meta: model = SomeModel fields = "__all__"" extra_kwargs = { "name": {"required": True}, "address": {"required": True}, "property": {"required": True}, } As you can see I am trying to add field kwargs by using extra_kwargs. The issue is that it won't work for a related field e.g. property or address field. I know I can just override it by defining a field manually and passing required=True, and that works but it's too long for my use case. Do you have any idea why this happen? Thanks. -

Url decoding problem on deployment with IIS and FastCGI on windows server
I realized an app front Angular, back-end Django, deployed on Windows server using IIS and FastCGI. This app serves media files on a certain URL. It works fine locally on dev server. I can access all my files correctly on path "medias/myfilepath". The problem is in production on IIS. Special characters are encoded in a different way. I think it is FastCGI that does it. I cannot find the encoding rules, and my Django app is not able to decode properly so my requests end up with a 404 error. Here are some examples of the difference of encoding between local server and production server : à | local : %C3%80 | prod : %25C0 ù | local : %C3%99 | prod : %25D9 É | local : %C3%89 | prod : %25C9 I can't find any documentation on the subject, I don't have access to configurations on CGI side. I could update decoding on Django side to fit it, but I can't find which one applies ... Someone would have some ideas on that subject ? -
