Parallel with Django using gevent
I'm trying to run some tasks in parallel in a Django view. Specifically, running queries from different databases at the same time. I've implemented the code, and the queries still run in series. To test, I've created simple parallel code: from gevent.pool import Pool def test(request): def run(i): print("Running " + str(i)) for j in range(1, 100000000): x = 2 / 2.2 pool = Pool(50) pool.map(run, range(1, 10)) The code also runs in series to my surprise Any idea what I'm doing wrong ? Is there some Django internal processes that blocks multi-threading ? How would I go about implementing parallel processes if gevent is not the answer ? -

so i'm still on my todo list and i want to know when an activity has passed so as to flag it as expired. my views.py def progress(request): activities = ToDo.objects.all() today = timezone.localtime(timezone.now()) context = { 'activities' : activities, 'today' : today, } return render(request, 'percent.html', context) in my templates i have it as: {% for activity in activities %} {% if activity.end.date < today.date %} {{activity}} <br> {% endif %} {% endfor %} i'm going to add my models.py for referencing class ToDo(models.Model): owner = models.ForeignKey(User, on_delete=models.CASCADE) todo = models.CharField(max_length=50) description = models.TextField(max_length=200, blank=True) created = models.DateField(auto_now=True) end = models.DateField() start = models.DateField() completed = models.BooleanField(default=False) def __str__(self): return f'{self.owner} - {self.todo}' or would it be easier to add an expired boolean field to my models? i'm so confused -
How to import a object of another model (A) inside model (B) in Django?
I want to create a new object in model B when specific condition are met in Model A, I am new to Django so that I am unable to figure out how exactly I can achieve this. For example I have two models( Product and Product Variant), when specific condition on Product Variant is met then I want to calculate new object value in Product Model.

Django Rest Framework returning duplicate data when returning a nested json response
I have a pricing table that contains the following fields: id, date, price_non_foil, price_foil, card_id. This table holds pricing data for each card for each day. For Example: "23a6c413-7818-47a8-9bd9-6de7c328f103" "2021-12-08" 0.24 0.80 "2ab9aecc-ce3c-4aaa-bf3c-fe9da4bba827" "c51a72ab-f29f-4465-a210-ff38b15e83a1" "2021-12-05" 1.27 0.80 "2ab9aecc-ce3c-4aaa-bf3c-fe9da4bba827" "17289b71-3b73-4e16-a479-25a7069a142e" "2021-12-09" 0.38 0.80 "2ab9aecc-ce3c-4aaa-bf3c-fe9da4bba827" "fa88f619-ec32-4550-9a57-c77b6e1a8e11" "2021-12-07" 1.27 0.80 "2ab9aecc-ce3c-4aaa-bf3c-fe9da4bba827" "f996d6cb-7d98-415c-bd70-2fca8f4e03a5" "2021-12-06" 1.27 0.80 "2ab9aecc-ce3c-4aaa-bf3c-fe9da4bba827" "2f8c00f3-4d47-478d-a653-7d7a476e9bae" "2021-12-09" 0.43 3.33 "2e5e1d78-0818-4ecd-a8f0-37e280aaa30a" "15b20912-4103-4e08-8f91-fed820b761af" "2021-12-05" 0.66 5.08 "2e5e1d78-0818-4ecd-a8f0-37e280aaa30a" Currently there is pricing data for 5 dates for each card.

Returning labels within validation errors in Django rest framework
When there are some validation errors on a request, DRF returns a dict object containing all the errors, something like this: { "first_name": [ "This field may not be blank." ], "last_name": [ "This field may not be blank." ], "email": [ "This field may not be blank." ] } Is there anyway to change this behavior and make it to automatically return field names in each error? something like this: { "first_name": [ "First name field may not be blank." # <<< The label of field: first_name ], "last_name": [ "Last name field may not be blank." ], "email": [ "Email field may not be blank." ] } or even a list: [ "First name field may not be blank.", # <<< The label of field: first_name "Last name field may not be blank.", "Email field may not be blank.", ] Note that I have more than of 80 end-points and serializers; I can't re-define all fields that are being automatically generated by ModelSerializers to add error_messages parameter. first_name = serializers.CharField( write_only=True, min_length=5, error_messages={ "blank": "First name field cannot be empty.", "min_length": "First name field is too short.", }, ) -
Forbidden (403) CSRF verification failed. Request aborted. Reason given for failure: Origin checking failed does not match any trusted origins
Help Reason given for failure: Origin checking failed - https://praktikum6.jhoncena.repl.co does not match any trusted origins. In general, this can occur when there is a genuine Cross Site Request Forgery, or when Django’s CSRF mechanism has not been used correctly. For POST forms, you need to ensure: Your browser is accepting cookies. The view function passes a request to the template’s render method. In the template, there is a {% csrf_token %} template tag inside each POST form that targets an internal URL. If you are not using CsrfViewMiddleware, then you must use csrf_protect on any views that use the csrf_token template tag, as well as those that accept the POST data. The form has a valid CSRF token. After logging in in another browser tab or hitting the back button after a login, you may need to reload the page with the form, because the token is rotated after a login. You’re seeing the help section of this page because you have DEBUG = True in your Django settings file. Change that to False, and only the initial error message will be displayed. You can customize this page using the CSRF_FAILURE_VIEW setting. -

How do you modify manytomanyfield in form in django?
I was wondering how you can change the value of a many-to-many field in a django form. Preferably, I would like to change the value within the def form_valid of my Modelview. Here is a part of the form_valid in my view that I am having trouble with: lesson = Lesson.objects.all().first() for i in lesson.weekday.all(): form.instance.weekday.add(i) form.instance.save() Here, weekday is a many-to-many field. However, the form saves the "submitted" values of the weekday by the user, and not the changed one as shown in the above code. Interestingly, the below code works, although it is not a many-to-many field: form.instance.name = lesson.name form.instance.save() Thank you, and please leave any questions you have. -

How to set user access restrictions in Django
first question. Is there a way to set access rights for a function without giving a conditional expression in django template? Currently, the code below is the code I wrote. If user click the "Click" text, a modal window is created depending on the condition, and if the condition is not met, a message window indicating that you do not have access rights is displayed. However, I think it is unnecessary to enter these conditions every time. {% if request.user.first_name in class.teacher|split:"/" %} <div data-toggle="modal" data-target="#relation_{{ class.id }}" class-id="{{ class.id }}">Click</div> {% else %} <a onclick="alert('You do not have access rights..');" class="col-form-label col-10 show-whitespace" style="cursor:pointer">Click</a> {% endif %} Second question. This example is similar. Through the conditional expression in the template, if the job of the current login account is 'principal', the Principal button is displayed. If it is not the principal job, the Principal button is not displayed on the screen. However, even if it is not a principal, user can connect by entering the '/class/principal/list' url directly. Is there a workaround? {% if job_title == 'principal' %} <a class="btn nav-link nav-link-button" href="/class/principal/list"> <span>principal</span> </a> {% else %} <a class="btn nav-link disabled nav-link-button" href="/class/principal/list"> <span>principal</span> </a> {% endif %} -
how to upload multiple files and use charfields at the same time in django rest framework?
