Django cant find static files 404error
I'm using django to create apps in the project. I'm going to make common files into templates and static folders under the project folder of the project. However, when the server is running, the files in the templates are found well, but the files in the static folder are not imported. I tried a few attempts through a search, but it didn't work, so I ask questions.

Store user input using forms or models in Django?
I have a Django ML web app where the user inputs some values and the ML models calculates a value and return it. What I want to do is save those values entered by the user and later use those values to retrain the ML model. Basically the user input should be saved in the database and later I should be able to fetch it for retraining. I have a couple questions regarding this: 1.) Should I use forms for saving user input or should I use models? 2.) What is the difference between using forms or models for saving user input? Any links/material/tutorial would be appreciated! Thanks! -

Django Consecutive Days and Max Consecutive days Query
I have a following model. class CategoryModel(BaseModel): name = models.CharField(max_length=100) icon = models.ImageField(upload_to=upload_icon_image_to) description = models.CharField(max_length=100) user = models.ForeignKey(User,on_delete=models.CasCade) def __str__(self): return self.name The basic idea is that whenever a user added a category In one day whether being 1 or 20 records it is regarded as 1 streak and if the user again adds a new category then it is regarded as a +1 streak so current streak will be 2 and max streak is also 2 if user consecutively adds for 5 days streak is 5 days as it is max streak. I just want to display as { "current_streak":3, "max_streak":12 } here current streak is 3 but previous streak set was 12 so it regarded as max streak Any Idea how I can achieve this query? -

(django) how to flatten an array inside of a dictionary to an array only
I am currently trying to handle the nested data in django. In my case, I want to remove the key "event_log" and flatten it to a simple array of dictionary only. { "event_log": [ { "date": 12-12-2000, "point": 500 }, { "date": 12-12-2001, "point": 700 } ] } The outcome should look like this: [ { "date": 12-12-2000, "point": 500 }, { "date": 12-12-2001, "point": 700 } ] I have tried adding a to_representation method to the serializer: class EventDateSerializer(serializers.ModelSerializer): event_log = EventLogSerializer(many=True, read_only=True) class Meta: model = EventDate fields = ['event_log'] def to_representation(self, instance): data = super().to_representation(instance) flatten_data = data['event_log'] for item in flatten_data: for key, value in item.items(): data[key] = value return data However, it turns out this method can only flatten nested dictionary instead of array inside of dictionary. Has anyone got an idea on how to flatten the array inside of the dictionary? Much appreciated. -
