I created a form for adding products to an e-Commerce site. The form isn't working perfectly. First issue: I want to store the user automatically by submitting the form.

Why DecimalField are serialized sometimes as number sometime as string numer
I have a django app with rest framework and I noticed that some DecimalField are serialized as string, others as numbers. Why? Here's my model: class TestModel(models.Model): quantity1 = models.DecimalField("quantity1", default=0.0, max_digits=10, decimal_places=3) quantity2 = models.DecimalField("quantity2", default=0.0, max_digits=10, decimal_places=3) quantity3 = models.DecimalField("quantity3", default=0.0, max_digits=10, decimal_places=3) latitude = models.DecimalField(max_digits=9, decimal_places=6) longitude = models.DecimalField(max_digits=9, decimal_places=6) Here's the serialization "quantity1": "1.000", "quantity2": "1.000", "quantity3": "1.000", "latitude": 45.49907, "longitude": 9.18749, I am aware of the problem of serialize floating point and their precision (see here), but why quantities are represented as string while lat/lon are numbers? They are both decimalFields... -
how to start overriding file after it reaches certain size?
Is there a way to start overriding a file when it reaches, for example, 50 MB size?

Then, I want to start overriding, I mean saving the new lines of text but delete the text from the beginning of the file. How do I do that? -

How to create a timetable in the shape of a donut chart with django
I want to make a webpage that manages time using Django. Managing the time I'm talking about means checking the start time and end time of an activity and displaying it on a donut chart with a specific color. Currently, only temporary html is created. I want to display a donut chart on a calendar. <div class="footer"> <div class="input_content"> <form> <label>Input activity</label> <input> <button>play / pause</button> <button>stop </button> </form> </div> </div> html above: enter image description here Example image I want to draw in html: enter image description here What I am currently thinking about is: Enter a color and activity in html and press the play button to save data (date, color, activity, start time) to Django's sqlite, and press the end button to save the end time to sqlite. Render the donut chart in html using the saved data (date, color, activity, start time, end time) using views.py. Activities on the same day should be displayed on one chart. I'd like to ask if what I'm thinking of is implementable, or if there is a better way. Thank you in advance. -

Azure SDK for Python: Copy blobs
For my current Python project I' using the Microsoft Azure SDK for Python. I want to copy a specific blob from one container path to another and tested already some options, described here. Overall they are basically "working", but unfortunately the new_blob.start_copy_from_url(source_blob_url) command always leads to an erorr: ErrorCode:CannotVerifyCopySource. Is someone getting the same error message here, or has an idea, how to solve it? I was also trying to modify the source_blob_url as a sas-token, but still doesn't work. I have the feeling that there is some connection to the access levels of the storage account, but so far I wasn't able to figure it out. Hopefully someone here can help me. -

How to replace get_declared_classes() from CakePHP to Python?
I have been moving website made in Cakephp into Django. In one place I found get_declared_classes(). I thinks this function returns list of previously used classes before running current class. First time when I encounter this, I just store list of classes manually in one file and I was using that and this solution worked only for a particular web page but Now I have multiple pages calling this class and everytime list of classnames are very different so I can not store class name list. If question is not clear please let me know, I can provide more information. Is there any other library that can replace this function in Python? Or Is there any other solution I can try ? -

I tried to search for answers, but after a few days, I'm here asking: I'm a beginner, making a todo list app - expanding on a tutorial I followed. Currently, it's filtering by user, which is fine, but I also want to filter by a field in the DB (list). Models: class ToDoList(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE, null=True, blank=True) title = models.CharField(max_length=200) description = models.CharField(max_length=200) created = models.DateTimeField(auto_now_add=True) def __str__(self): return self.title class Meta: ordering = ['created'] class Task(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE, null=True, blank=True) title = models.CharField(max_length=200) description = models.TextField(null=True, blank=True) complete = models.BooleanField(default=False) created = models.DateTimeField(auto_now_add=True) list = models.ForeignKey(ToDoList, on_delete=models.CASCADE) def __str__(self): return self.title class Meta: ordering = ['complete'] View I'm trying to change: class TaskList(LoginRequiredMixin, ListView): model = Task context_object_name = "tasks" def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['tasks'] = context['tasks'].filter(user=self.request.user) context['count'] = context['tasks'].filter(complete=False).count search_input = self.request.GET.get('search-area') or '' if search_input: context['tasks'] = context['tasks'].filter(title__startswith=search_input) context['search_input'] = search_input return context Also, is there a way to access the list variable in the html component, like here? url: path('tasks/<list>/create', TaskCreate.as_view(), name="task-create"), html: <a href="{% url 'tasks' 'task.list' %}">&#8592; Back</a> -
all cloud platforms like Heroku and digital ocean require billing card
Hi I want to deploy my Django app to Heroku and when I want to use add-ons like ClearDB MySQL it requires me to verify my account by giving Heroku my billing card the problem is I'm in a country that is restricted by US law and we don't have global cards so I cant use mine as I searched all over the web for cloud platforms it seems that all of them require such verification do you have any solution for that ? or any platform that won't require such verification?
