How can I make my ReportLab table data wrap when data is sent from Django views?
I've been trying to get my cell strings to wrap, the table gets too wide and out of screen. I know that using Paragraph automatically wraps text, but the problem is that I'm sending my data from multiple views so the table width and number of columns varies. I've gotten errors like 'list' object has no attribute 'split', 'tuple' object has no attribute 'split' and even 'Paragraph' object is not iterable. class ComprasPDF(View): def get(self, request, *args, **kwargs): arr= [( o.unidad_inventario.control_stock.almacen, o.unidad_inventario.control_stock.producto, o.proveedor, o.cantidad, o.costo_unidad, ) for o in CompraProducto.objects.all()] data = { 'nombre':'COMPRAS', 'headings':('ALMACEN', 'PRODUCTO', 'PROVEEDOR','CANTIDAD','COSTO POR UNIDAD'), 'query': arr } pdf = generar_pdf(request,data) return HttpResponse(pdf, content_type='application/pdf') And using it on ReportLab like this. As you see, I'm using the data I'm sending directly and I don't know how to apply paragraphs styles to the query data. buff = BytesIO() doc = SimpleDocTemplate(buff,pagesize=A4) story = [] headings = data['headings'] alldata = data['query'] t = Table([headings] + alldata*10) t.setStyle(TableStyle( [ ('GRID', (0, 0), (-1, -1), 1, colors.black), ('BACKGROUND', (0, 0), (-1, 0), colors.gray) ] )) story = [Spacer(0,25),t] doc.build(story, onFirstPage=primera_pagina, onLaterPages=add_numero, ) And the table looks like this.

Can I use Django and Django Rest Framework together?
I am pretty new to Django and I have a question which I can't find an answer and feel confused about it. I have web based system where only admin can create users. I need to use JSON Web Token for Cross Login but the only way I found to implement this is with Django REST Framework. My current app is only Django based right now. My question is can I use both Django and Django REST Framework together so I can make my JWT for this part, but stayed with Django where is possible? -
Celery response queue is consuming but not acknowledging
I have a django application that has a rest endpoint which puts tasks in a queue and waits for the result through a callback. Unfortunately this leads to the callback function being executed, but the task is never acknowledged or consumed from rabbit. Means it stays in the queue even though the callback method finishes. The response that remains in the queue looks like after consuming (but also before): This is the code in the rest-framework: def post(self, request): individual_request = {'dummy': 'data'} task_id = my_task.apply_async( kwargs=individual_request, link=my_task_success.s(individual_request), link_error=my_task_error.s(individual_request), ) In another part of my code I have the function my_task registered as a task with: @task(queue='queue_name', name='task_name', soft_time_limit=10800) def my_task(dummy=None): ... do stuff ... return {'success':True} In the same code file I have the response tasks: @task(bind=True, queue=celery_config.DATA_EXTRACT_QUEUE) def my_task_success(self, result, individual_request): LOGGER.info( 'Successfully finished task' ) @task(queue=celery_config.DATA_EXTRACT_QUEUE) def my_task_error(context, error, stacktrace, individual_request): LOGGER.error( 'Failed to execute task' ) -

How to offset timezone on the Back-End using Django?
I would like to ask for support for this problem. Basically, I am working on an app in which it will generate values based on the current month, date, and year let's say Company ID based on the user's preference while leaving the TZ on settings.py untouched. I live in the timezone 'Asia/Manila', however, I have read some devs discussing that setting the Django TZ other than 'UTC' is problematic so I'm leaving it as is. But, my app requires users to save generated Company ID based on their own user-configured timezone. I know it's easy to reflect the user's timezone on the frontend via a template, however, I would like my to do something like that as well on the back-end and I'm not really sure how. I have already read the documentation many times but I still can't it. I want it to be as 'Django' as possible. -
Django doesn't see the 'templates' and 'static' folders
I am coming from Django 1.x of which everything worked fine in regards of the said problem. I tried starting a new project in Django 3.x the same way I start projects on the older version. The problem I noticed is in regards of the templates and static directories. After I set them up, Django doesn't seem to "detect" them in some way and my IDE (PyCharm) doesn't suggest them when I point something on those directories. I use the same IDE on both the old and new versions of Django. Here is the structure of my project: myproj |_ myapp |_ myproj |_ templates |_myapp |_ base.html |_ index.html | |_ static In my settings.py: import os BASE_DIR = Path(__file__).resolve().parent.parent TEMPLATE_DIR = os.path.join(BASE_DIR, 'templates') TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [TEMPLATE_DIR], 'APP_DIRS': True, Now, when I use {% extends "app/base.html" %} on my index.html, it doesn't 'suggest' the base.html (of which in older versions of Django it does suggest it) so something must be wrong. Here's an example: But placing myapp/base.html, it would still work. Compared to an older project of mine which uses Django 1.x: Not just in the template files but almost everywhere in Django like … -
Python cursor how do I replace with a string and maintain quotation marks in a SQL que?y
I'm using django. I'm having trouble replacing the email string in the query. It needs quotations around it since it compares strings. I've tried using parameters on the execute function but that did not work: cursor.execute("SELECT password,id FROM account WHERE email = %(mail)s", {'mail': userEmail}) I get a DatabaseError at / ORA-00936: missing expression q = "SELECT password,id from account WHERE email = '%s'" % userEmail cursor.execute(q) This produces a correct SQL query with the quotations. But I've heard this is a bad idea due to sql injection. Regardless, I'm getting a ORA-00933: SQL command not properly ended error when I did this. -

How to configure & enable OpenID Connect in DJango+Wagtail app?
I'm currently using the python-social-auth/social-core lib with a DJango app, which is configured (and working) to authenticate Wagtail CMS users with our (free) Azure Active Directory Tenant. Our NFRs stipulate that authentication should occur using OpenID Connect and to this end we've installed "social-auth-core" with the "openidconnect" extra like this in requirements.txt: ... social-auth-core[openidconnect] social-auth-app-django ... Again, things seem to work A-OK and users can login, but here's my problem - and I know I'm missing something here: As far as I know, OpenID Connect is simply a modification/addition to OAuth2.0 that gives OAuth super powers of authentication - not just authorisation - but I don't know if my DJango+Wagtail app is now just automagically configured to "just work" as/with OpenID Connect, or whether there's some additional logic/validation/config/whatever that I need to apply to the app. I don't see anything relevant in the official python-social-auth docs for Azure AD, and I don't see how/if I need to explicitly enable OpenID within Azure AD itself. Can anyone help? Thank you. -
Django/DRF: How can I get more than one slug_field from serializers.SlugRelatedField?
I have a serializer to populate an AJAX table that looks something like this: class BookSerializer(seralizers.ModelSerializer): author = serializers.SlugRelatedField( many=True, read_only=True, slug_field="name" ) class Meta: model = Book fields = ( "name", "author", "slug" ) author can contain any number of authors, which is why I need to handle it this way. Currently I can print out the name of the book and link it with its slug. I also get a list of author names rather than the IDs. My question is how I can also get the slugs for each author page? I would like to link each author to its own page, but using something like author.slug doesn't work, nor did adding this: author_slugs = serializers.HyperlinkedRelatedField( many=True, read_only=True, view_name="slug" ) Then I added author_slugs to fields -- this threw an error that author_slugs is not a valid field in the Book model. Is there a way to access more than field for each author? -

Django displays tow different timezones for the same model attribute when viewing in admin site vs a query for the model in a script
How to make consistant timezone across Django. In my settings.py I have TIME_ZONE = 'America/New_York' and USE_TZ = True.

Django: How to override the display of ModelForm fields in UpdateView, specifically
I have a function-based view that is currently working successfully. However, I want to learn how to create the equivalent Class Based View version of this function, using the generic UpdateView class -- though I imagine the solution, whatever it is, will be the exact same for CreateView, as well. I know how to create and use Class Based Views generally, but there is one line of my function-based view that I have not been able to work into the corresponding UpdateView -- as usual with the Generic Editing Class Based Views, it's not immediately clear which method I need to override to insert the desired functionality. The specific task that I can't port-over to the CBV, so to speak, is a line that overrides the queryset that will be used for the display of a specific field, one that is defined as ForeignKey to another model in my database. First, the working function-based view, with highlight at the specific bit of code I can't get working in the CVB version: @login_required def update_details(request, pk): """update details of an existing record""" umd_object = UserMovieDetail.objects.select_related('movie').get(pk=pk) movie = umd_object.movie if umd_object.user != request.user: raise Http404 if request.method != 'POST': form = UserMovieDetailForm(instance=umd_object) …
