Django RegexValidator causing AttributeError in Django Admin
I'm using a RegexValidator pretty simply in my User Model: name_regex = RegexValidator(r"^[a-zA-Z0-9\s_]*$") name = models.CharField( _("Name"), default=generate_default_name, max_length=constants.USER_NAME_MAX_LENGTH, help_text=_("The user's display name."), validators=[name_regex], ) But when I use the standard Django UserAdmin I get this error whenever I try to save any field which confuses me greatly: 'RegexValidator' object has no attribute 'search' I don't do anything with search, nor do I reference RegexValidator at all in my standard instantiation of the userAdmin. admin.site.register(User, UserAdmin) Any ideas? -
django User.objects.create() is throwing error
here is the view to signup a user: @api_view(['POST']) def registerUser(request): # data is successfully passed from client data=request.data print("register data", data) try: print(data['name']) print(data['email']) print(make_password(data['password'])) # Everything prints so far but nothing after here user = User.objects.create( first_name=data['name'], username=data['email'], email=data['email'], password=make_password(data['password']) ) print("userrrrrrr",user) # serializer=UserSerializerWithToken(user, many=False) # dont login the user message={"detail":"Successfully registered"} # return Response(serializer.data) # I just want to send a simple message return Response(message) except: message={'detail':"User with this email already exists"} return Response(message, status=status.HTTP_400_BAD_REQUEST) I put notes on code. Data is received and I print everything. BUt User.objects.create() is causing an error so except block gets executed and i am getting error. I also tried User.objects.create_user() but getting same error. User.objects.create( first_name=data['name'], username=data['email'], email=data['email'], password=make_password(data['password']) ) -
Disable Bootstrap warnings from Django Compressor
Is there any way to disable warnings from Django compressor when compressing files? Currently when I'm compressing the files I get a lot of warnings like this: WARNING: The `make-container-max-widths` mixin has been deprecated as of v4.5.2. It will be removed entirely in v5. We're statically hosting Bootstrap, so I don't really care about those messages. I'd really just like them not to show up. -
How to make a chart from uploaded JSON file on webpage?
I have looked at options such as Google Charts, Charts.JS, Pandas, Any chart, etc, but I still feel a little stumped on direction to go forward. I want the chart to grab files saved on the admin side with url: http://127.0.0.1:8000/admin/infographicsite/filesupload/ and make a graph based on any JSON file uploaded to the webapp. There's also percentages/calculations done on a separate file that I will also bring in to connect with so graph can correctly represent said percentages. one JSON file that was uploaded looks like this: { "results":[ { "gender":"female", "name":{ "title":"Mrs", "first":"Debra", "last":"Johnston" }, "location":{ "street":{ "number":2192, "name":"Bridge Road" }, "city":"Coventry", "state":"Shropshire", "country":"United Kingdom", "postcode":"YK74 9FX", "coordinates":{ "latitude":"6.6918", "longitude":"111.6380" }, "timezone":{ "offset":"+5:45", "description":"Kathmandu" } }, "email":"debra.johnston@example.com", "login":{ "uuid":"475c314c-bd42-49b5-b81c-8016ddb1b5e3", "username":"smallleopard142", "password":"beach", "salt":"YqjLSvmF", "md5":"26436a12fdaa430eebb3c39236554b4f", "sha1":"cc972754b8164c7e48dab2e01ef2c107d110006b", "sha256":"8015b915af908793db031cd3e27a67883f0aeb674777fdc8b6226352155b57b4" }, "dob":{ "date":"1949-12-12T14:53:42.446Z", "age":72 }, "registered":{ "date":"2009-10-04T09:05:27.022Z", "age":12 }, "phone":"017687 39061", "cell":"0752-951-872", "id":{ "name":"NINO", "value":"ZT 33 57 79 M" }, "picture":{ "large":"https://randomuser.me/api/portraits/women/84.jpg", "medium":"https://randomuser.me/api/portraits/med/women/84.jpg", "thumbnail":"https://randomuser.me/api/portraits/thumb/women/84.jpg" }, "nat":"GB" }, { "gender":"female", "name":{ "title":"Miss", "first":"Gül", "last":"Türkyılmaz" }, "location":{ "street":{ "number":3425, "name":"Filistin Cd" }, "city":"Kilis", "state":"Antalya", "country":"Turkey", "postcode":32073, "coordinates":{ "latitude":"-15.1737", "longitude":"14.2954" }, "timezone":{ "offset":"-11:00", "description":"Midway Island, Samoa" } }, "email":"gul.turkyilmaz@example.com", "login":{ "uuid":"257f4418-270d-4002-9e84-6e33d9e82a71", "username":"smallpeacock303", "password":"ashley", "salt":"HegxAbaa", "md5":"b5a339d4d6eb3eebe51c437b99ab82ae", "sha1":"aebe19b90d0bc7701fc93ebeb9b251c90d31d08d", "sha256":"c871b4709aa301bf1cf09de5296ad96813a8818e3362860a6b260103502844e5" }, "dob":{ "date":"1993-03-08T17:29:09.139Z", "age":28 }, "registered":{ "date":"2003-02-02T01:58:10.729Z", "age":18 }, "phone":"(324)-499-6198", … -
Django Form after redirect is empty after successfully submitting a form
I have a template called courses for the url http://127.0.0.1:8000/gradebook/courses/. This template lists existing Course objects loads the CourseForm form. The form successfully creates new objects. If I go to the addassessment template with url http://127.0.0.1:8000/gradebook/addassessment/7/, it correctly loads the AssessmentForm. I want to submit this form and then return to the previous courses template. The AssessmentForm submits and the object is saved, but when it redirects back to the courses template, the CourseForm does not load. The courses template loads, the expect html loads correctly other than the form fields.

Pandas and confusion over passing by value and passing by reference
A function returns a Pandas DataFrame. I try to create a new DataFrame with "newFrame = myFunction()". But the newFrame variable acts more like a reference than a distinct object. Can you help? In these snippets, FrameMaker.py updates a DataFrame object on a timer. It has a function get_frame that returns that DataFrame object. Multiple scripts call that function to get a copy of the DataFrame. GetFrameData.py is an example. It calls the get_frame function and assigns the returned value to a variable. It should then have its own copy of the DataFrame, and anything it does to its copy of the DataFrame should have no effect on any other copies. But it does cause an effect. GetFrameData.py drops columns from the DataFrame. The first time that runs, the "values.drop" line runs successfully. The second time it runs, it gives an error that the DataFrame doesn't have the columns in question. It's like the 'values' variable is a reference to the DataFrame in FrameMaker.py, not a distinct object in the GetFrameData stack. Kind of like how Strings function in most languages. How should I change my code to get a copy of the DataFrame object, not a reference? FrameMaker.py def … -
Having Trouble Creating Nested LISP-Style List in Python
I have a list of functions and values I'd like to put into a nested list. I'd like the result to be a LISP style list(something that looks close to some LISP style executable code) that I can easily process later. This list comes from a "sentence", that gets split into a list by word - it keeps defined phrases (multi word) together, by checking any multi-word tokens in the DB first, gluing them and then separating them later. Any words not in the database are ignored. Punctuation is also ignored. It just matches actual stored Tokens. This lets me write a sentence that can get translated into functions I can process later. We can ignore the fact that these are functions, and just think of them as strings, since that's how they're stored, but functions and arguments describe the use case perfectly, since that's what they are. Functions will be the first item in a list, followed by their arguments in the same list. A function with no arguments will be in a list with only that one element. An argument that is itself a function will be in a list(with it's arguments, if any). The number of arguments … -
Django convert pdf to image
I'm receiving a PDF via form post and before uploading it into my models, I would like to convert it to an image (I'm using the library pdf2image). I'm able to work with a temporary file of the PDF and convert it to an image but I haven't been able to save the image into my models. Any idea?? Here's what I've got so far.

Syncing Django Models with Overriden Save Method
I have a client and a user model. Both client and user have a flag called help_desk. The help desk clients and users are to be kept in sync. This means that: When user is marked as help_desk they are added to all help desk clients When user is unmarked as help_desk they are removed from all help desk clients When a client is marked as help_desk all help desk users added to it When a client is unmarked as help_desk all help desk users are removed from it I've been trying to solve this by overriding the save() method with the following: Client def save(self, *args, **kwargs): help_desk_users = get_user_model().objects.filter(is_help_desk=True) if self.help_desk: for user in help_desk_users: self.users.add(user) else: for user in self.users.all(): if user in help_desk_users: self.users.remove(user) super().save(*args, **kwargs) User def save(self, *args, **kwargs): if self.is_help_desk: for client in Client.objects.filter(help_desk=True): client.users.add(self) else: for client in Client.objects.filter(help_desk=True): client.users.remove(self) super().save(*args, **kwargs) The user code is working as expected but the client code is not. I think the reason is because you are unable to bulk update in an overriden save method - see docs. My question is, is this simply a limitation of Django? And if so, what are the best … -
Django json field sorting on first ip address

So the ideal order should be, 1.1.34.13 10.248.91.72 172.19.128.1 When I do normal Django sorting it prints in order as below, UserIP.objects.filter(id__gt=100).values('ip_addresses').order_by('ip_addresses') 1.1.34.13 172.19.128.1 10.248.91.72 Please advice what would be the solution. -
Django Save Image In Different Formats Using Pillow
I have this site I am making for my school and I need to optimize it, like a lot. So I decided to serve all my images compressed and in next-gen formats like jpeg-2000 and webp. Using Pillow, this is what I have so far: class Bulletin(models.Model): banner = models.ImageField(upload_to='banner/', blank=True) def save(self, *args, **kwargs): super().save() if self.banner: image = Image.open(self.banner.path) resized = image.resize((1600, 900)) resized.save(self.banner.path, quality=50) So I think that this compresses the image (plz tell me if I made mistake with code above). So now I want to be able to save this image in multiple formats I want the one uploaded image to be saved in these formats: webp jpeg2000 jpeg I am thinking of creating more fields on my model banner, like the field banner_webp, and then I would just convert it to webp and during save I would save the converted image to that field. The problem is that I don’t know how to convert image using Pillow, or how to do what I am asking. Thanks for help. -

Django model abstract model with constrains not being inherited: 'constraints' refers to field 'xxx' which is not local to model 'Foo'
I am using Django 3.2 I have come across a strange behaviour which appears to be a bug; Fields used in constraints defined in a ABC are not inherited by child classes. myapp/models.py class BaseFoo(models.Model): content_type = models.ForeignKey(ContentType, on_delete=models.CASCADE,related_name='%(class)s_content_type') object_id = models.PositiveIntegerField() content_object = GenericForeignKey('content_type', 'object_id') user = models.ForeignKey(User, blank=False, null=False, on_delete=models.CASCADE,related_name='%(class)s') created = models.DateTimeField(auto_now_add=True) class Meta: abstract = True constraints = [ models.UniqueConstraint(fields=['content_object', 'user'], name="'%(class)s_unique"), ] class Foo(BaseFoo): class Meta(BaseFoo.Meta): abstract = False No problem when I makemigrations, but, When I attempt to migrate the schema (`python manage.py migrate), I get the following error: myapp.Foo: (models.E016) 'constraints' refers to field 'content_object' which is not local to model 'Foo'. HINT: This issue may be caused by multi-table inheritance. Why is Foo not inheriting the fields clearly defined in the parent ABC? - and how do I fix this (assuming it's not a bug)? -

Loading Django static files from React component
I am fairly new to React/Django/web development in general. I know there are a lot of questions on SO about how to load static files in Django templates, but I couldn't find anything helpful on how to do this in React components. Scenario: I am building a React-Django app, and one of the features is to render a PDF document based on some user input. I am able to render the pdf successfully with react-pdf if the file is stored somewhere in the react app's source tree. However, I want to serve these pdf files from the backend.
