How can I create objects in for loop in Django?
Only data coming to database is one record with one key and one value (and this is the last one from frontend). How can I send many records to my database in objects.create()?

How to sort a list(queryset) containing a manytomany field
Python: 3.9.10 Django: 4.0.3 I am using Django Paginator. To sort the data on each page, and only the data on that page, I am converting my queryset to a list and then sorting the list by its key using attrgetter(). My model contains two ManyToManyFields and so I cannot sort it using the standard sorted() method as I receive the error message: TypeError: '<' not supported between instances of 'ManyRelatedManager' and 'ManyRelatedManager' I think I understand why this is happening - sorted() cannot compare two lists (manytomanyfields) against each other and determine which is greater than or less than - so therefore the list(queryset) cannot be sorted in this way. I imagine I probably have to iterate through the list(queryset), get the first value of the manytomanyfield and then somehow sort everything by that. I am not what the best way is to go about doing this. models.py class DataExchange(models.Model): name = models.CharField(unique=True, max_length=15, null=True) def __str__(self): return self.name class DataSource(models.Model): name = models.CharField(unique=True, max_length=10, null=True) def __str__(self): return self.name class Provider(models.Model): name = models.CharField(unique=True, max_length=15, null=True) exchange = models.ManyToManyField(DataExchange, related_name="providers_exchange") source = models.ManyToManyField(DataSource, related_name='providers_source') score = models.IntegerField(null=True) def __str__(self): return self.name Paginator helper function: def paginator_helper(request, paginator): page … -
How to turn a LightGBM model into a web-app?
everyone, I'm new to Machine learning. Recently, I've built a LightGBM model with 30 features. The model works great. Then, my boss wants me to build a web app for this model which allows the user to input the data and return the prediction to the users. He wants a web app like this project: http://wwwnew2.hklii.hk/predictor. I don't know where to start. In my understanding, I might need an input form then pass the values to the model and then return the prediction to the front-end. However, I totally had no idea how to get started. Here are my questions: How can I pass the value to the trained model and return the result? Should I build the front-end with Django? Is there any python library that allows me to build such a web app easily? Should I host the web app on a VM? Thank you very much. -
