Lack of correct display of Persian in PDF format in Django
I used reportlab in Django to make a pdf of Persian words in Django as follows: from reportlab.pdfgen import canvas from reportlab.lib.units import inch from reportlab.lib.pagesizes import letter import io from django.http import FileResponse from django.conf import settings import reportlab def pdf(request): reportlab.rl_config.TTFSearchPath.append(str(settings.BASE_DIR) +'/static') pdfmetrics.registerFont(TTFont('Samim','Samim.ttf')) buf=io.BytesIO() c=canvas.Canvas(buf,pagesize=letter) txt=c.beginText() txt.setTextOrigin(inch,inch) txt.setFont('Samim',14) lines=[ 'سلام', 'خوبی', 'چه خبر' ] for l in lines: txt.textLine(l) c.drawText(txt) c.showPage() c.save() buf.seek(0) return FileResponse(buf,as_attachment=True,filename='me.pdf') But the output is as follows: I also used other fonts like Nazanin but the result did not change and I even used the xhtml2pdf library but the result was still in this format. In fact, there is a problem with the output format, which must be right to left, which is left to right, unfortunately! How should I solve this problem? -
Error while deploying Django to Heroku using GitHub
I am trying to deploy my GitHub repository on Heroku, the build is successful but when I am going to the domain it is showing an Application Error and the logs are showing this. What I think: I am sure that the problem is in INSTALLED_APPS setting in settings.py. Heroku isn't recognising my 'app_name', may be some namespace problem.

Django generic.ListVIew: display list item's details on the same page (~ combine ListView and DetailView)
Roughly speaking, what I want is combine generic.ListView with generic.DetailView, but display the clicked ListView item's details on the same page. What I've done is: generic.ListView of Contacts: from .models import Contact from django.views import generic class ContactList(generic.ListView): model = Contact context_object_name = 'contacts' template_name = 'contacts/list.html' The contacts/list.html template includes a JS Fetch request (GET) to get the clicked item: {% block content %} {% if contacts %} <ul> {% for contact in contacts %} <li><a id="{{ contact.id }}" onClick="showDetails(this.id)">{{ contact.first_name }}</a></li> {% endfor %} </ul> {% else %} No contacts. {% endif %} <div id='contactDetail'></div> <script type="text/javascript"> function showDetails(contactId){ console.log(contactId); fetch(`http://127.0.0.1:8080/contacts/${contactId}`, { headers: { 'Accept': 'application/json', 'X-Requested-With': 'XMLHttpRequest', }, }) .then(response => { // should 500 be processed? return response.json(); }) .then(data => { //Perform actions with the response data from the view window.onload = function() { // build html markup next document.getElementById("contactDetail").innerHTML= ...; } }) } </script> {% endblock content %} The Django view that handles this Fetch-GET request is: from django.shortcuts import get_object_or_404 from django.forms.models import model_to_dict def contact_details(request, contact_id): contact = get_object_or_404(Contact, pk=contact_id) contact = {k: v for k, v in model_to_dict(contact).items() if v} return JsonResponse(contact) Is it the correct way? -

Return monthly sales value in Django
I've got some simple models below class Stamping(models.Model): created = models.DateTimeField(auto_now_add=True) class Meta: abstract = True class Product(Stamping): user = models.ForeignKey(User, on_delete=models.CASCADE, related_name='user_product') name = models.CharField(max_length=300, unique=True) price = models.FloatField() class GroupProductOrder(Stamping): user = models.ForeignKey(User, on_delete=models.CASCADE, related_name='group_product_orders') product = models.ForeignKey(Product, on_delete=models.SET_NULL, null=True) quantity = models.IntegerField() class Order(Stamping): user = models.ForeignKey(User, on_delete=models.CASCADE, related_name='orders') fulfilled = models.BooleanField(default=False) products = models.ManyToManyField(GroupProductOrder, blank=True) @property def total_price(self): cost = 0 for product in self.products.all(): cost += product.total_price return cost Now I want to query the database and return some details on a monthly basis. Details like total number of sales for each month and sum of sales for each month. I've tried using annotate but it seems can't pass model property in it. What is the best way to tackle this problem? Example of expected output is {'month': 'October', 'count': 5, 'total': 15} -
Exchanging data between django apps in the same project
I would like to exchange data between two django apps that are coming from a single big app that due to the increasing size and functionalities we decided to split. Specifically I need to retrive only a string in one app from the other. Litterally a 10 character string. The only thing that I found at the moment that satisfies me, since I would like to avoid import stuff from the other app (to me it seems not a clean way to do it, in the other case please change my mind), is making an http request from one app to the other. Anyway I found it overkill. Is there a clean way to achive this without using http request or imports? -
no such table: operational error in django
I run makemigrations followed by migrate but still I get the error when I try to populate DB with dummy values that no such table exists. This happens for one single table. Here is my models.py file for the table: class G(models.Model): desc = models.CharField(max_length=charLen256) points = models.IntegerField(default=0) add = models.BooleanField(default= False) complete = models.BooleanField(default=False) Here is what I try to do in my populate script: def add_goal(item): g = G.objects.get_or_create(desc=item['description'], points=item['points_earned'])[0] g.save() Can anybody spot the problem or error. I happen to have researched a lot but did not find any suggestion other than running makemigrations and migrate.

I want to multiple user authentication with django social oauth2 and simpleJWT(Normal register form and social auth together)
I want to use two types of user login in my django project. One of them is the form that asks for information such as email and password, which is the traditional method, and the other is the login process using social media accounts. However, in the video I watched, he first deletes the simpleJWT module he had made before, and then only uses the oauht2 module. I am very confused at this point. I want both types of user input, how can I do that? Here is the video And here is the doc. of oauth2 module -
Create a form with specific changed_data in django for testing purposes
I've overridden ModelAdmin.save_model in order to trigger a task if a certain field was changed. Basically something like: def save_model(self, request, obj, form, change): obj.save() if "field_name" in form: transaction.on_commit(lambda: trigger_task()) Now I'm trying to write a unit test that checks whether this task will be triggered in response to the field change. Only I'm having a hard time creating a form whose changed_data will contain that field. My test is currently something like: @patch(...) def test_task_should_trigger_if_field_changed(self, mocked_task): admin = MyAdmin(model=MyModel, admin_site=AdminSite()) form = MyForm({"field_name": "changed"}, initial={"field_name": "initial"}) ... admin.save_model(request=MagicMock(), obj=my_model, form=form, change=False) The test above won't create a form whose changed_data contains field_name and the task will never be triggered. At this point, I'm considering creating a mocked object that will return that famed form.changed_data["field_name"] but I'm wondering if I'm missing something or is there a simpler way of doing this. -
Channels group_send method doesn't send data until method ends
I am developing the app with private chat between 2 users. There are 2 consumers: chat consumer for receiving/sending messages and chats consumer for receiving messages from all chats of the user. When the consumer receives a message, it should broadcast data into all clients that are connected to websocket, so I use self.channel_layer.group_send method. After that, I have to do some data checks and transformation and send new data into all clients from another websocket (chats websocket). The problem is that data transformations can take some time (DB calls, services, etc), but the first group_send call won't send any data until method receive ends. For example, if I put asyncio.sleep(10) between group_send calls - the data won't be received by clients for 10 seconds. async def receive(self, text_data): await self.channel_layer.group_send(f"chat_{self.sender}_{self.receiver}", text_data) ... #some data transformation or checks await self.channel_layer.group_send(f"all_chats_{self.sender}", transformed_data) -

Replacing template with another with Django
I am trying to find a way to replace only a section of a web page with another template based on the change of a drop down. Also I don't want the rest of the page to reload. I'm using jquery to call the function when the drop down is changed so that's not an issue. The closest way I have is to use ajax replace the contents of a div with something else but when I try to pass a django tag that would refer to another html template, the string "{% include 'upgrading_template.html' %}" prints on the page rather than reading it as an include statement. I have also tried methods like replaceWith() but I get the same result. $.ajax({ type: 'GET', url: {% url 'sw_upgrade' %}, data: parameters, success: function (response) { document.getElementById('upgrade_template').innerHTML = "{% include 'upgrading_template.html' %}"; } }) -
Use of same serializer class for post and get request in Django rest framework
I have a Student model which has some fields. What I need is I want to create a student object using post API with certain fields and however needs to show some other fields while doing get request. For eg: My model: class Students(models.Model): name = models.CharField(max_length=255,blank=True) email = models.EmailField(unique=True) phone = models.CharField(max_length=16) address = models.CharField(max_length=255,blank=True) roll = models.IntegerField() subject = models.CharField(max_length=255,blank=True) college_name = models.CharField(max_length=255,blank=True) Now my serializer will look like this. class StudentSerializer(serializers.ModelSerializer): class Meta: model = Student fields = ['id','email','name','phone','roll','subject','college_name', 'address'] Suppose, I have a view that handles both post and get api (probably using APIView), then what I need is, to create a student object I only need name, phone and email. So for post api call, I only need three fields whereas while calling the get api I only need to display the fields name, roll, subject, and college_name not others. In this situation, how can I handle using the same serializer class?? -
