Django - Import CSV to model, handling relationships to other models
Let's suppose we have Author and Book models: class Author(models.Model): first_name = models.CharField(max_length=60) last_name = models.CharField(max_length=60) def __str__(self): return self.last_name class Book(models.Model): title = models.CharField(max_length=60) author = models.ForeignKey(Author, on_delete=models.CASCADE) def __str__(self): return self.title And we try to do multiple inserts using CSV files: (author.csv) FirstNameA, LastNameA FirstNameB, LastNameB (book.csv) FirstTitle, LastNameA AnotherTitle, LastNameA OneMoreTitle, LastNameB I try to build a class-based view which imports a CSV in a model. The view: is given the name of the model as an argument fetches the model and its fields and uses get_or_create method in a loop for each row of the CSV While this approach works class ImportCSV(View): ... def post(self, request, model_name): model = apps.get_model('app', model_name) fields = list(modelform_factory(model=model, fields='__all__').base_fields.keys()) file = request.FILES['csv_file'] decoded_file = file.read().decode('utf-8').splitlines() reader = csv.reader(decoded_file) for row in reader: dict = {} for i, field in enumerate(fields): dict[field] = row[i] _, created = model.objects.get_or_create(**dict) While it works for Author model, it does not work for Book model, due to ForeignKey field. It expects an id (number), not the value that __str__ returns for this record. It is totally logical. The question is, how can I handle such an import? What I would like to tell Django to … -

Uncaught DOMException: Blocked a frame with origin "http://localhost:8000" from accessing a cross-origin frame
I am currently building a website with Django and Javascript. I am working on the ajax calls that would the data needed for populate my homepage. However, I keep getting this cross-origin error. I have tried setting the document domain, enabling CROS headers and passing CSRF tockens. All attempts have been unsuccessful. Please take a look at my javascript code above. if (window.scrollY > news_elementTarget.offsetTop) { if (!news_fetched) { $.ajax({ url: '/ajax/home', type: 'get', data: { button_test: $(this).text(), section: 'news', CSRF: csrftoken, }, success: function (response) { console.log('success') create_section_1(response.id, response.sections) news_fetched = true } }) } } I'm trying to make an ajax call to the backend when the window scrolls to a certain div. The get request is never even sent to the backend. I really confused because I thought my domains are the same which wouldn't cause a Cross-origin error. -
Django Rating for both side
I am writing an application for service based. When a user purchase a service, then the seller can leave a rate to the order for buyer and also the buyer can leave a rate to the order for seller. Like think about fiverr , upwork, freelanecr guru, when you sell a service or buy a service, you can leave review as buyer or as a seller which you are!! My logic is same, i am not getting should i add to models or should i handle with same models. Here you go for my current models class Ratings(models.Model): order = models.OneToOneField( Order, on_delete=models.CASCADE, related_name="ratings" ) seller_comment = models.TextField(_("Rating Body")) seller_value = models.IntegerField() buyer_comment = models.TextField(_("Rating Body")) buyer_value = models.IntegerField() seller = models.ForeignKey( User, on_delete=models.CASCADE, related_name="+", ) buyer = models.ForeignKey( User, on_delete=models.CASCADE, related_name="+", ) You know above models solving both buyer and seller case but i found this is not best practice. in other side, also i am thinking this way. class BuyerRatings(models.Model): order = models.OneToOneField( Order, on_delete=models.CASCADE, related_name="ratings" ) comment = models.TextField(_("Rating Body")) value = models.IntegerField() author = models.ForeignKey( User, on_delete=models.CASCADE, related_name="rating_as_buyer", ) class SellerRatings(models.Model): order = models.OneToOneField( Order, on_delete=models.CASCADE, related_name="ratings" ) comment = models.TextField(_("Rating Body")) value = models.IntegerField() author … -

Django API challenge using Django and Django Rest Framework
guys! So, I have the following challenge and I have a question about it. Should I use the name of the actions for the urls?

Django admin filter by foreign model's property retrieved by raw sql
How do I filter using a property. I know this is a duplicate, but existing answers that I think would work is not doing it for me.

Django - Recommendations for Django Tagging library packages
So I'm just about to begin implementing a "tags" feature in to my app where my users can create posts representing certain "tags" similar to the StackOverflow tags feature. I've just come across Tagulous but I wanted to first know if anyone may recommend any other tagging libraries? Ideally, I'm wanting to use a tags library where I can manage singular and nested tree type tags from my Django Admin. Any suggestions would be welcomed! -

Combine existing models into one unmanaged model Django
I've currently got existing tables in my database that were created with models as per the usual way (using makemigrations and migrate). Now, I am looking to combine certain data from these existing tables, without having to create a new table in my database. Then, I would like to serialise that data to make it accessible via the views APIs. My understanding is that I create an unmanaged model to handle this. I understand as part of the docs that you need to specify managed = False but that's just a start. So far, I've literally only found one link (that isn't very helpful): https://riptutorial.com/django/example/4020/a-basic-unmanaged-table- Let's say hypothetically, I've got user information that is inputted in many different tables in my existing database and I'd like to create certain data points within my new and unmanaged model to combine it into one serialiser. As of now, this is what I've come up with. Note that in my user model, I don't know what to specify for my db_tables parameter since, like I mentioned, data will be coming from many different tables, not just one. UserModel from django.db import models class UserModel(models.model): user = models.CharField(db_column="LABEL", max_length=255) class Meta: managed = False … -
how can I fetch the specific ids data( multiple ids are stored in list) using Django
I want to fetch data of multiple ids which is provided from the User Interface and these ids are stored in a list. So how can I retrieve the data of these ids using Django ORM? When I try the following approach It returned nothing def selectassess(request): if request.method=='POST': assess=request.POST.getlist("assess") quesno=request.POST.getlist("quesno") subid=request.POST.getlist("subid") print(quesno,subid) print(assess) max_id = Sub_Topics.objects.all().aggregate(max_id=Max("id"))['max_id'] print(max_id) pk = random.sample(range(1, max_id),3) subss=Sub_Topics.objects.raw("Select * from Sub_Topics where id=%s",(str(pk),)) context4={ 'subss':subss, } print(pk) return render(request,"assessment.html",context) By applying the below-mentioned approach I can get only one id-data which is specified by typing the index value. But I want to get the data of all ids which are stored in the list so how can I get my required output by using Django ORM def selectassess(request): if request.method=='POST': assess=request.POST.getlist("assess") quesno=request.POST.getlist("quesno") subid=request.POST.getlist("subid") print(quesno,subid) print("youuuuu") print(assess) max_id = Sub_Topics.objects.all().aggregate(max_id=Max("id"))['max_id'] print(max_id) pk = random.sample(range(1, max_id),3) sub = Sub_Topics.objects.filter(pk=pk[0]).values('id','subtopic') context4={ 'sub':sub, } print(pk) return render(request,"assessment.html",context4) -
Override django-ckeditor bullet style class
I have a django application that I'm using with tailwind, and I'd like to be able to apply the tailwind classes to my bullet lists by default. I have tried adding a custom style in the config.js file as well as the styles.js file, but for some reason it doesn't seem to update with any changes I make there? I've tried running collect static but it says files are unmodified 0 static files copied to '/code/myproject/static', 1280 unmodified. config.js CKEDITOR.editorConfig = function( config ) { // Define changes to default configuration here. For example: // config.language = 'fr'; // config.uiColor = '#AADC6E'; config.format_p={element:"p", name: "Normal", styles:{ 'color': 'red'}}; }; styles.js CKEDITOR.stylesSet.add( 'default', [ ] ); I don't have the bullet styles there yet, but even the paragraph change is not picking up. I realise I can do this with javascript to add class to all ul and li elements, but I'd rather not do that if there's a cleaner solution. -
Understanding Django exclude queryset on ForeignKey relationship

How can I make one out of two fields required in my model/serializer?
I'm trying to allow my user to input either their email or their phone to continue. I've read a bunch of answers on here but none of them seem to work.

Django. Moving a redis query outside of a view. Making the query results available to all views
My Django app has read-only "dashboard" views of data in a Pandas DataFrame. The DataFrame is built from a redis database query. Code snippet below: # Part 1. Get values from the redis database and load them into a DataFrame. r = redis.StrictRedis(**redisconfig) keys = r.keys(pattern="*") keys.sort() values = r.mget(keys) values = [x for x in vals if x != None] redisDataFrame = pd.DataFrame(map(json.loads, vals)) # Part 2. Manipulate the DataFrame for display myViewData = redisDataFrame #Manipulation of myViewData #Exact steps vary based from one view to the next. fig = myViewData.plot() The code for part 1 (query redis) is inside every single view that displays that data. And the views have an update interval of 1 second. If I have 20 users viewing dashboards, the redis database is getting queried 20 times a second. Because the query sometimes takes several seconds, Django spawns multiple threads, many of which hang and slow down the whole system. I want to put part 1 (querying the redis database) into its own codeblock. Django will query redis (and make the redisDataFrame object) once per second. Each view will copy redisDataFrame into its own object, but it won't query the redis database over and … -

Create an already populated dashboard with a displayed graph in Atoti using Django
I'm not sure how to word this differently but I'm integrating Atoti with a Django project using their project template, I've searched a lot in their documentation but I can't seem to get an answer about this. What I need to do is after a button click on a Django view, redirect the user to a custom Atoti Dashboard that's already populated with a specific information already displayed (for example, a line graph with a title). I don't need to save it unless the user wants because we're planning on using Atoti mainly as means of visualization. At this point in time, I can only redirect the user to the standard Atoti dashboard with my information and then create what I need to display but that's not user friendly at all and presumes the user has knowledge with Atoti. Anyone know if this is possible and if isn't, anyone has any suggestions on good Data Visualization libraries that make use of Django? Thanks in advance. -

settings.py MEDIA_ROOT = os.path.join(BASE_DIR, 'media') MEDIA_URL = '/media/' models.py class Product(models.Model): name = models.CharField(max_length=250) image = models.ImageField() tables.py import django_tables2 as tables from .models import Product class ProductTable(tables.Table): class Meta: model = Product fields = ("image" ,"name") views.py In the views.py , I filter the model objects and get QuerySet import django_tables2 as tables from .models import Product from .tables import ProductTable ----- table = ProductTable(new_objects) #new_objects is Product QuerySet return render(request, 'home.html', {'table': table }) Outcome I got a table, but instead of images, only links. How can I display the image?
