Overview of using Authorization Code grant type to authenticate a user in django
I have a django app that Im using drf and ReactJS for my frontend and token authentication. I've been messing around with various packages in Django so that I can implement Social Authentication. I was using implicit authorization but am wanting to switch to an Authorization Code Grant Type. I have been able to make the request, redirect to a callback url on my server where I am able to make a post request to get the user data, refresh token and access token. This is where I have gotten a little stuck because Im not sure how to return those tokens to the frontend. After I authenticate I need to be able to redirect to a "success" page but dont know how to inlcude the access token in that redirect. I know I could use django sessions and just store the tokens there and use that for my authentication but I was hoping to use Token authentication where the user includes their access token to access secure data. I was able to come up with two "working" solutions. With Set-Cookie response = HttpResponseRedirect("/login-success") response.set_cookie("access_token", "<access_token>") return HttpResponseRedirect Appending <access_token> return HttpResponseRedirect("/login-success#<access_token>") # parse token when page is reached I … -
Order Django queryset by annotated field and annotate it again
I need to order Django queryset by annotated field and then annotate result with row number. Steps: Add complex_order field to QuerySet that defines extra logic for future ordering. Order QuerySet by new field and old fields (complex_order, order and id) Annotate sorted QuerySet with number using RowNumber() function. Sample code that almost works queryset.annotate( complex_order=Case( When( Q(foo__type=FooType.ONE.value) | Q(foo__isnull=True) then=Value(1), ), default=Value(0), ), ).order_by( '-complex_order', 'order', 'id' ).annotate( number=Window(expression=RowNumber()) ) But I have a problem with wrong number annotation. After inspecting the SQL query I noticed that annotation happens at the same time with ordering. SELECT "table.id", ... CASE WHEN ("foo"."type" = ONE OR ("foo" IS NULL)) THEN 1 ELSE 0 END AS "complex_order", ROW_NUMBER() OVER () AS "number" FROM ... ORDER BY 32 DESC, "table"."order" ASC, "table"."id" ASC I need to annotate queryset second time, right after sorting it. Or maybe there is a better way to add iterable number for each row in queryset? -
MySQL Query exclude item when blank
I have this issue in my Query which is I can't perform the actual output that I expected, so let say I have this all data in my table named Tev_incoming ID code slashed_out status 1 23-09-00001 1 2 23-09-00002 1 3 23-09-00003 2023-09-18 22:45:46.099847 3 4 23-09-00004 2023-09-18 22:42:14.785251 3 5 23-09-00005 2 8 23-09-00004 3 9 23-09-00003 2 I have this query now SELECT * FROM tev_incoming t1 WHERE (code, id) IN ( SELECT DISTINCT code, MAX(id) FROM tev_incoming GROUP BY code )AND `status` IN (1,3) I have this result to my query provided ID code slashed_out status 1 23-09-00001 1 2 23-09-00002 1 4 23-09-00004 3 Expected output ID code slashed_out status 1 23-09-00001 1 2 23-09-00002 1 As you can see in all data there is duplicate code, it has two duplicate of 23-09-00004 I want to exclude 23-09-00004 because the slashed_out is blank which is status is equals to 3. I tried MAX(id) just to choose the max Id of the duplicate codes. Now How can I modify my query which has conditions I've mention above. -

Connection problem to related_name in save_model function in Django
There is a model called Borrow. Inside BorrowLine model, a ForeignKey is defined with related_name lines. I write BorrowAdmin and BorrowLineInline for Borrow model. Inside BorrowAdmin class I used the save_model function as follows: def save_model(self, request, obj, form, change): obj.save() print(obj.lines) return super(BorrowAdmin, self).save_model(request, obj, form, change) But when I add an instance of Borrow model in Django administration, the following line is printed in the console: borrow.BorrowLine.None and I don't have access to any of the BorrowLine fields. For example, one of its fields is book, but when I call it, it gives this error: 'RelatedManager' object has no attribute 'book' How can I fix this problem and access the class fields? my codes: class Borrow(models.Model): student = models.ForeignKey('student.Student', on_delete=models.CASCADE, related_name='borrow') created_time = models.DateField(auto_now_add=True) delivery_time = models.DateField(default=date.today() + timedelta(days=7), validators=[delivery_time_validator]) delivered = models.BooleanField(default=False) def __str__(self): return str(self.student) class BorrowLine(models.Model): borrow = models.ForeignKey('Borrow', on_delete=models.CASCADE, related_name='lines') book = models.ForeignKey('book.Book', on_delete=models.CASCADE, related_name='lines') def __str__(self): return f'{self.borrow} -> {self.book}' def clean(self): book = self.book if not book.is_available: raise ValidationError(f'The book {book.title} is not available.') class BorrowLineInline(admin.TabularInline): model = BorrowLine extra = 1 max_num = 3 autocomplete_fields = ('book',) @admin.register(Borrow) class BorrowAdmin(admin.ModelAdmin): inlines = (BorrowLineInline,) list_display = ('student', 'created_time', 'delivery_time', 'delivered') search_fields = … -

Django: query to iterate through a column values and search match in another table

Implement Recurring Classes/Events
I have to implement upcoming classes functionality. Upcoming classes can be repeated weekly or monthly. User will only create it once and repeat logic should be handled from back end. There should be no data duplication. Listing api should return the first 10 upcoming classes where date >= today date. Add live or upcoming Class Upcoming Class listing The last tried solution is: calculate the next 100 dates based on weekly or monthly interval and store it in a list named repeated_dates. write a scheduler which will get the last repeated date and if it less than today date then calculate the next 100 dates and update the list. filter out upcoming classes based on repeated_dates list. The issue is: If I filter out from list, I only get the class object. I don't know which date is matched. If there is only two classes, then it should return 1st 10 classes from these two based on dates >= today date. But in this solution, it will only return 2. Here is the model: REPEAT_CHOICES = ( ('no_repeat', 'Does not repeat'), ('repeat_weekly', 'Repeat Weekly'), ('repeat_monthly', 'Repeat Monthly'), ) def image_path(instance, filename): if filename: extension = filename.split('.')[-1] else: extension = "png" … -

Django concurrency bug handling
I have an API written in Django that provides user with the list of files that they have. There is also a delete API that can delete a File that the user has. However, there is a bug where a GET request after a deletion still shows the previously deleted object. The GET API uses a filter query on the Files object. While the DELETE API will delete a given file id from the list, by getting and calling .delete(). After googling around, it seems like I need to wrap the database queries into a transaction.atomic block and perform select_for_update() in both of the APIs. Will this solve the issue? By right, if the GET Request is done after receiving the DELETE response it should not ever have this concurrency bug right ? It is only if we sent the requests concurrently. But, select_for_update is locking the database row right? So, will the GET API be able to still read the currently being deleted row? Is this the correct way of handling, or do I need to somehow change the isolation level of the database. Currently the DB is Postgresql which defaults to "Repeatable Read". After reading around, this is … -
Django PostgreSQL - Indexes on JsonField vs. custom fields
I am working on a booking system on Django with the following context: Users can create Items for others to book They can further specify the 'available time' per weekday (mon-sun), i.e. opening_time & closing_time. We can also expect that: A. most users adopt the same 'default' values across 7 weekdays (i.e. override when necessary), and B. most users adopt the same default values, say 8am-10pm. A search on Items by its availability, e.g. "Monday 3-4pm", will be expected and of considerably high traffic, so query performance is a must. I have a few options in mind but cannot decide which is better: Option A: Default values + JsonField + index from django.db import models from django.contrib.postgres.fields import JSONField class Item(models.Model): opening_time = models.TimeField() closing_time = models.TimeField() override = JsonField() class Meta: indexes = [ models.Index(models.F("override__sun_open"), name="override__sun_open"), models.Index(models.F("override__sun_close"), name="override__sun_close"), ... ] The Json will 'override' if necessary - might look something like {'sun_open': 07:00, 'sun_close': 23:00}. The filter() will be more complicated but can save on storage (given most users will use the defaults). Option B: JsonField + index class Item(models.Model): available = JsonField() class Meta: indexes = [ models.Index(models.F("available__sun_open"), name="available__sun_open"), models.Index(models.F("available__sun_close"), name="available__sun_close"), ... ] The query will be easy … -

Django On Delete IntegrityError

ArrayField is empty even after serializer.save() (Django and Postgres)

Google Places API returns diferent street number which was given in auto complete

I search a street name and number "Rua Augusta, 300": But after selecting it the response cames with other number options instead of the choosen one. Does anyone knows what could be happening? It does happens with other addresses even where I live in. :-) Thank you very much!
