Display a results from using foreign key - django
I'm looking to display clients information. A client is registered then they can fill out different forms, I need those forms to be attached to the client and display the latest 4 forms in an area on the same page as the client details. model.py class Casenotes(models.Model): FORMREG = models.ForeignKey(Register_Client, blank=True, null=True, on_delete=models.CASCADE) FORMREGCOUN = models.ForeignKey(Register_Counsellor, blank=True, null=True, on_delete=models.CASCADE) DATEADDED = models.DateField(auto_now=True) NOTES = models.TextField(blank=True) def get_absolute_url(self): return f"/case/{self.id}/" class Register_Client(models.Model): DATEADDED = models.DateField(auto_now=True) TITLES = ( ('MR', 'Mr'), ('MISS', 'Miss'), ('MRS', 'Mrs'), ('OTHER', 'Other') ) TITLE = models.CharField(max_length=5, choices=TITLES, blank=True, default=None) FIRST_NAME = models.CharField(max_length=50) LAST_NAME = models.CharField(max_length=50) views.py def registerclient(request): #register a client if request.method == 'POST': form = RegisterClientForm(request.POST) if form.is_valid(): form.cleaned_data saved = form.save() return redirect(saved.get_absolute_url()) else: print("Invalid form") print(form.errors) else: form = RegisterClientForm() return render(request, 'HTML/ClientRegistration.html', {"form":form}) def registeredclient(request, id): #display the registered client obj = get_object_or_404(Register_Client, id=id) content = { "obj": obj, } return render(request, 'HTML/Client.html', content) -
Creating a csv from request data and saving it into a model field - Django
I have a model that includes a text field and a file field. A user can either upload a csv file or some text which I should parse into a csv and save it in the file field. It goes something like this class UserUpload(models.Model): ...... ...... filefield = file_uploaded = models.FileField(upload_to='media/', validators= FileExtensionValidator(allowed_extensions=['csv'])], blank=True, null=True) datafield = models.TextField(blank=True, null=True) In the serializer import csv class UserUploadSerializer(serializers.ModelSerializer): ..... def csv_parser(self, datastream): with open('test,csv', 'w') as csv_file: data_writer = csv.write(csv_file) for x in datastream: data_writer.writerow(x) return csv_file def create(self, validated_data): if 'datafield' in validated_data: output_file = self.csv_parser(validated_data['data_uploaded'].split(", ")) return UserUpload.objects.create(filefield=output_file, **validated_data) else: return UserUpload.objects.create(**validated_data) Upon working with this logic I always get an error saying _io.TextIOWrapper object has no attribute '_committed' which i figured it might do with the Django FileContent class but when I tried that, it didn't succeed. Any help on how I can figure this out? -
How to call a app endpoint from within app django
Let's say I have a django app that is running on http://127.0.0.1:8000/ That app has an endpoint called homepage which renders a view and on the view there is a button. When that button is pressed, I want to call an API endpoint (button_pressed) within my django app, for example http://127.0.0.1:8000/button_pressed (this should return JSON) Would I have to just do a normal XMLHttpRequest to http://127.0.0.1:8000/button_pressed in JS when the button is pressed? Or is there another, better way to do it? -

Why does the view function render more than one instance of the form field?
Please I need help with the code below. I'm trying to make an ajax call that renders the create_post view on a modal page. But it renders multiple instances of the form fields, instead of one. def save_room_form(request, form, template_name): data = dict() if request.method == 'POST': if form.is_valid(): form.save() data['form_is_valid'] = True rooms = list(Room.objects.all().values()) data['html_room_list'] = render_to_string('sharespace/includes/partial_room_form.html', {'rooms': rooms}) else: data['form_is_valid'] = False context = {'form': form} data['html_form'] = render_to_string(template_name, context, request=request) print(data.items()) return JsonResponse(data) def create_post(request): if request.method == 'POST': form = RoomForm(request.POST) else: form = RoomForm() return save_room_form(request, form, 'sharespace/shareform.html') ajax call: $(function () { var loadForm = function () { var btn = $(this); console.log("before ajax") $.ajax({ url: btn.attr("data-url"), type: 'get', dataType: 'json', beforeSend: function () { $("#modal-room").modal("show"); }, success: function (data) { $("#modal-room .modal-content").html(data.html_form) console.log("clicked"); } }); }; //Create room $(".js-create-room").on("click", loadForm); }); My sanity check suggests the problem is from the view(i think). Any help will be appreciated. Thanks -
Multiple for loops (not nested) in Django Template and the second one not working
I'm facing the following problem: On the view.py I send to the view template a list, such as: return render(request, 'template.html', {'images': list}) Then on the template I make a for like: {% for img in images %} {{ img }} {% endfor %} and on other part of the template again I do: {% for img in images %} {{ img }} {% endfor %} but this second time the code doesn't even enter inside the loop, it looks like the cursor of the for is pointing to the last element of the array, is that right? how to fix it, I mean, move this cursor to the first position, supposing this is the case. -

How to properly serve a Django application throught Twisted's Web server?
I am building a system that was some components that will be run in its own process or thread. They need to communicate with each other. One of those components is a Django application, the internal communication with the Django app will not be done through HTTP. Looking for networking libraries I found Twisted (awesome library!), reading its documentation I found that Twisted implements the WSGI specification too, so I thought its Web server could serve WSGI applications like Django. Following the docs I come with the following script to serve the Django app: from twisted.web import server from twisted.internet import reactor, endpoints from twisted.web.wsgi import WSGIResource from twisted.python.threadpool import ThreadPool from mysite.wsgi import application as django_application # Create and start a thread pool to handle incoming HTTP requests djangoweb_threadpool = ThreadPool() djangoweb_threadpool.start() # Cleanup the threads when Twisted stops reactor.addSystemEventTrigger('after', 'shutdown', djangoweb_threadpool.stop) # Setup a twisted Service that will run the Django web app djangoweb_request_handler = server.Site(WSGIResource(reactor, djangoweb_threadpool, django_application)) djangoweb_server = endpoints.TCP4ServerEndpoint(reactor, 8000) djangoweb_server.listen(djangoweb_request_handler) reactor.run() I made a django view that does a blocking call to time.sleep() to test it, it worked fine. Since it's multithread, it did not block other requests. So I think it works well with … -

How to create user groups for permissions within code (not in admin)
I'm wanting to create user groups for permissions and am wondering how to do this in the code as it sounds like the more proper way to do it (or not?).

DataTables: Retain rows/data even after page refresh
I am using DataTables version 1.10.20 in my Django project. I have two DataTables in a page, one for Products and another for Cart. The data in Products table is sourced by AJAX call. The user will add the products from products table to cart table by clicking on a add button. User should be able to modify the quantity in the cart table and when satisfied, finally click on a checkout button. The checkout button will call some view for next steps to save the transaction. The problem is, before clicking on checkout, if the user refreshes the page after adding a couple of products or navigates to a different page, the Cart DataTable is loosing all the data and the user will have to add them all over again. The data in Cart DataTable should be only cleared when "Checkout" is clicked. Is this possible ? I have tried using StateSave: true as documented here but it did not help. Here is my code.. DataTable for "Products" <script defer type="text/javascript" language="javascript" class="init"> // This function will initialilize the 'Products' datatable. $(document).ready(function () { $('#productstable').dataTable({ "ajax": { "url": "{% url 'getproductsdata' %}", "dataSrc": '' }, // Datatable customization options … -

UWSGI log to multiple locations
I'm a bit new to uwsgi so this may be a dumb question, I'm trying to get uwsgi to write logs to multiple locations and have not been able to find a way to do this. I'm want to setup uwsgi so it writes to both my logfile (/tmp/uwsgi.log) and stdout (so I can see it in the logs in my k8s pod). But I can't get both to work. I can only get one or the other to work. Here is my uwsgi.ini file: [uwsgi] root = %d/../test chdir = %(root) module=test.wsgi:application socket=/tmp/uwsgi_test.sock master=True pidfile=/tmp/uwsgi_test.pid vacuum=True max-requests=2000 logto=/tmp/uwsgi.log chmod-socket = 666 vacuum = true processes = %(%k * 4) enable-threads = True single-interpreter = True limit-as = 4056 buffer-size=65535 stats=/tmp/uwsgi_test_stats.sock Running this uwsgi file with /opt/conda/bin/uwsgi --ini /home/docker/uwsgi/k8s-sandbox-webserver.ini sends log files to only /tmp/uwsgi as specified by the logto parameter in the uwsgi.ini. If I remove the logto parameter completely then the logs only go to stdout. How can I make these uwsgi logs appear in both stdout and /tmp/uwsgi.log?

How do I let my django server print a receipt using my client's printer?
I'm working on a web application that allows users to add items to their cart. What I want to do is to print the items in the cart to a kitchen impact receipt printer on my clients side (I'm using the TM-U220 Receipt Printer). Currently, I am using my own computer to run the server but in the future, I hope I can get it working online so anyone can visit the website. I can't seem to find any solution on how to do that and if it is possible? I've only recently started Django and I can't seem to find a good solution. Any tips, help or idea on how to writing data to the printer on the client side from Django server?
