Can't download working dxf file generated by ezdxf from django server
Generated dxf file (ezdxf) from django server using below code: bio = io.StringIO() document.write(bio) # save to memory stream length = bio.tell() bio.seek(0) # rewind the stream response = HttpResponse( bio.getvalue(), # use the stream's contents content_type="image/x-dxf", ) response["Content-Disposition"] = 'attachment; filename = {0}'.format(cab.split(' ')[1] + ".dxf") response["Content-Encoding"] = "UTF-8" response['Content-Length'] = length return response is missing the last few lines, including the EOF line. Compared to a dxf file obtained simply by document.save() What needs to be added to the code so that the downloaded dxf file is identical to the saved dxf file? -

Switching from LDAP to AD LDAPS using Python Django
Converting authentication from LDAP to AD LDAPS Python + Django ============== Following Django Docs: https://django-auth-ldap.readthedocs.io/en/latest/authentication.html OLD: AUTH_LDAP_SERVER_URI = "ldap://ldap-example.test.com" NEW: AUTH_LDAP_SERVER_URI = "ldaps://ad.example.com" ============== I have worked with the AD administrator to set these values correctly. I changed the values themselves for obvious privacy reasons. AUTH_LDAP_BIND_DN = "cn=ex-test,cn=user,dc=test,dc=ad" AUTH_LDAP_BIND_PASSWORD = "{PASSWORD}" AUTH_LDAP_USER_SEARCH = LDAPSearch("ou=sites,dc=test,dc=ad",ldap.SCOPE_SUBTREE,"(uid=%(user)s)") AUTH_LDAP_CONNECTION_OPTIONS = {ldap.OPT_REFERRALS: 0} AUTH_LDAP_USER_DN_TEMPLATE = "cn=%(user)s,ou=sites,dc=test,dc=ad" AUTH_LDAP_BIND_AS_AUTHENTICATING_USER = True AUTH_LDAP_GROUP_SEARCH = LDAPSearch("cn=priv-ex,ou=due,ou=ldap,ou=shared,dc=test,dc=ad", ldap.SCOPE_SUBTREE) AUTH_LDAP_GROUP_TYPE = GroupOfNamesType(name_attr='cn') AUTH_LDAP_USER_ATTR_MAP = { "first_name": "usersName", "last_name": "usersLastName", "email": "usersEmail" } AUTH_LDAP_REQUIRE_GROUP = "cn=DUE-MAIN,ou=DUE,ou=Applications,ou=Sharing,o=LDAP" ============== Problem It will not work for login. I do not know what I am doing wrong as I am following the docs precisely. Questions Q1: Is there anyway I can test the connection from a terminal or command line? Q2: I have seen the django-pyad package recommened with a settings.py that looks like # settings.py AUTHENTICATION_BACKENDS = [ 'django_pyad.backend.ADBackend', ] # AD configuration AD_LDAP_SERVER = "ad.example.com" AD_NT4_DOMAIN = "example" AD_SEARCH_DN = "OU=Users,DC=ad,DC=example,DC=com" Should I scrap what I did for the previous LDAP tree and go this route instead? Or can I re-use the previous LDAP connection code but change the values for AD like I am doing now? -

Getting data from another Foreign key - DRF
The relations of tables are shown in the picture. I have a main Table named Product. Two tables ProductImage , OrderedProduct have a Foreign key set to it. Now, I want to retrieve the image from OrderedProduct. How should I write the code for Serialization for it? Thanks Models.py Visualization This is my model.py file: class Product(models.Model): name = models.CharField(max_length=50) description = models.TextField() def __str__(self) -> str: return self.name class ProductImage(models.Model): product = models.ForeignKey( Product, on_delete=models.CASCADE, related_name='product_images') image = models.ImageField(upload_to="images/", null=True, blank=True) class OrderedProduct(models.Model): product = models.ForeignKey( Product, on_delete=models.CASCADE, related_name='ordered_products') quantity = models.IntegerField() Serializers.py class OrderedProductSerializer(serializers.ModelSerializer): product_name = serializers.CharField(source='product.name') product_price = serializers.FloatField(source='product.price') # product_img = >>> what should I do here? <<< class Meta: model = OrderedProduct fields = ('user', 'product', 'quantity', 'delivered', 'product_name', 'product_price', 'product_img') I've read the documentation, asked in some programming groups but couldn't find any good solution.

How to upload an image to django from an html input file

Using Model.objects.filter in Form prevents me from updating Model
I have a form setup like this where I use the values from TestModel to create a select field in a form. However if I want to update the TestModel to add a new column, Django gives me a psycopg2.errors.UndefinedColumn saying the new column is not found on the table and the stack trace points back to this form ModelChoiceField. Its not until I comment out this select that I am able to make the migration to the database. So my question is there a better way to setup this ModelChoiceField where I don't have to comment it out to update the underlying model on the database? I'm using Django 4.0 and python 3.8 for reference. class TestModelChoiceField(forms.ModelChoiceField): """ Overwriting model choice field attribute to use a different __str__ representation than the default model """ def label_from_instance(self, obj): return obj.test_field class TestForm(forms.Form): first_select = TestModelChoiceField( queryset=TestModel.objects.filter(model_attribute__isnull=False), initial=TestModel.objects.filter(model_attribute__isnull=False) .filter(test_field="Yes") .first() .team_id, label="Field One:", ) -
Creating a simple multiple users app in Django
So I've created 3 different users: admins, developers, and project managers. When I use the individual signup forms for each of these users and log out, it works, but then I when try to use the login form, it seems to me that it's acting like the signup form. Because when I input the same user details as the one I just created into the login form, it throws up the built-in error message, 'A user with that user name already exists' I'm not sure how to proceed from here. Here's what I have so far. models.py class CustomUser(AbstractUser): ACCOUNT_TYPE_CHOICES = ( ('admin', 'Admin'), ('developer', 'Developer'), ('project_manager', 'Project Manager') ) account_type = models.CharField(max_length=20, choices=ACCOUNT_TYPE_CHOICES) login and signupviews class LoginView(View): def get(self, request): # Render the login form form = LoginForm() return render(request, 'users/login.html', {'form': form}) def post(self, request): # Get the form data from the request form = LoginForm(request.POST) # Validate the form data if form.is_valid(): # Get the username and password from the form username = form.cleaned_data['username'] password = form.cleaned_data['password'] # Authenticate the user user = authenticate(request, username=username, password=password) # If the user is authenticated, log them in and redirect to the homepage if user is not None: login(request, … -

Need help about redirecting views in Django
I a beginner in learning Django and have met with an issue that need everyone help. I'm working on a web application for reading novels.

I have the static folder in the correct spot at the project level and then a css file inside that followed by the style.css file. The Html page: {% load static %} <!DOCTYPE html> <html> <head> <title>My Website</title> <link rel="stylesheet" type="text/css" href="{% static 'css/style.css' %}"> </head> <body> <h1>Home</h1> <header> <nav> <ul> <li><a href="{% url 'home' %}">Home</a></li> <li><a href="{% url 'about' %}">About</a></li> <li><a href="{% url 'info' %}">Info</a></li> </ul> </nav> </header> </body> </html> The CSS page: h1 { background-color: orange; } From the research I've done this should get the backgrounds of all the h1 tags orange but it is not working.
