Python Django ModeulNotFoundError: No module named 'SomeFolder'
I have a django app. It is quite complicated, I can't post all the code here, so I have a big picture summary. The setup of the folders in the big picture related to what I'm doing is below. Note that "SomeFolder" is a placeholder name for the actual name. Some folder is a folder containing some python scripts with functions inside of them. It wasn't installed in the Django app. I dragged and dropped SomeFolder into the backend folder. This is necessary and had to be done. It's some python stuff unrelated to Django. Dashboard backend SomeFolder A.py B.py C.py views.py Dashboard frontend manage.py Inside of views.py at the top, I do import SomeFolder Then, inside of views.py, I have a function that calls some of the functions within the python scripts A.py, B.py, and C.py. This is why I need to import SomeFolder. For example: def someFunction(): SomeFolder.A_Function_1 SomeFolder.A_Function_2 SomeFolder.B_Function_2 etc. The issue is, when I run python manage.py runserver I get a ModuleNotFoundError: No module named 'SomeFolder' in views.py. The SomeFolder folder is in the same directory as views.py, so I'm not sure why it's not being recognized. I've seen other similar examples on stackoverflow, but didn't … -

drf> What can I do for using annotate from M2M model
I have 4 models like this. user model class User(model.Model): name=models.ChaField() diary model class Diary(): title=charfield author=Foreignkey("user.User") recommend_diary model class RecommendDiary(): section=Foreignkey("recommend.RecommendSection") diary=Foreignkey("diary.Diary") recommend_section model class RecommendSection(): section=charfield diaries=M2M("diary.Diary", through=RecommendSection) when I give to users recommend item, I want to make an annotation that excludes blocked users. The queryset given to me is this queryset=Recommend.objects.filter(start time-end time) So I can take an object of a given queryset and check numerous diaries associated with this object like this. obj=queryset.first() diary_queryset=obj.diaries.all() (I made custom manager for this) After checking that the request user is blocked from the user who wrote this diary, and I can exclude it from the queryset. diary_list=[diary for diary in diary_queryset if diary.id not in block_list] but I got a filtered list not Queryset. and it is not RecommendSection queryset even. can I get a excluded RecommendSection queryset from blocked user by using annotate or something else? I wanna exclude block user list from RecommendSection ex) queryset=RecommandSection.objects.exclude(diary_id__in=block_user) (it doesnt work btw) I wanna use .annotate if able thx for help. -
Django - Encrypt whole instance
I'm currently figuring out what would be the best way to encrypt an instance of a model in Django. Encrypting single fields seems easy, but I would like to encrypt a whole instance. Context I'm currently building a note-taking application which should have the ability to optionally encrypt a note using a given password. The model looks something like this: class Note(models.Model): title = CharField() content = TextField() created_at = DateTimeField() edited_at = DateTimeField() While I could simply only encrypt the title and content, I don't want that to avoid telling any information about a note when it is encrypted. So basically all fields (event created_at and edited_at) should be encrypted. Thoughts I thought about adding a second model EncryptedNote which only holds a field encrypted_data. This field contains the data in a JSON format in an encrypted form. When the application needs to load the instance, it will decrypt the content and create a Note instance based on the JSON data. However, it feels a little bit off to manually save JSON when using a SQL-like database. Question Is there already a good (and secure) way to encrypt an instance or is this idea of manually encrypting and decrypting … -

Access "Browser" location
We all have seen this prompt: As far as I know, this is not IP-based location. This is device-based location. I don't want IP-based location because 1) It's not reliable and 2) If the user browses my website with a VPN, the location data is absolutely wrong. I've searched PyPi.org and DjangoPackages.org but didn't find anything to implement that in my Django app. Is there any solution? -
How to make a dynamic query builder in Django
I am working on a small project where I need to make complex queries that can be grouped in a logical format. For example consider an table Books, and we need to select certain books based on filters such as 5 books from (author_reputation > 4 && recent_sale_rating > 3) AND 7 books from (book_length < 150 || recent_sale_rating > 4) So a total of 13 Books are selected using the above two queries. I was trying to figure out a way to use django FilterSet for this, finding it difficult to work through it. Also tried other libraries like djangoql etc. Any help or guidance on how to look at the problem will be of great help! -

how to get time since from datetime field

Version control for Custom Postgres Function in Django
I have a custom postgres function in my Django app. Keeping it up to date with migrations works, but is very hard to code review / move changes from the DB to the migration, because each migration is an entire new block of SQL, like so: def update_func(apps, schema_editor): schema_editor.execute( """ CREATE OR REPLACE FUNCTION public.function() .... ect Does anyone have a similar situation and know a better way to version control the function? -

Transforming SQL Query to Django Expression
Assuming I have the following Django models and the according SQL-Tables with some data: UserAnswer: | id | answer | partquestion_id | |----|--------|-----------------| | 1 | 667 | 1 | PartQuestion: | id | question_id | |----|-------------| | 1 | 1 | Solution: | id | content | question_id | |----|---------|-------------| |1 | 667 | 1 | |2 | 85 | 2 | I want to get all User answers where the answer is equal to the solution of the according question. I've came up with this SQL-Query but can't really think of how to implement this into a Djano query: select * from (useranswer join partquestion on useranswer.partquestion_id = partquestion.id) join solution on partquestion.question_id = solution.question_id where answer=content; This will output the following: | id | answer | partquestion_id | id | question_id | id | content | question_id | |----|--------|-----------------|----|-------------|----|---------|-------------| | 1 | 667 | 1 | 1 | 1 | 1 | 667 | question_id I just can't get my head around this concept in Django. Maybe using F-Expressions and some stuff. Thanks for any advice. -
Autoincrement field dependent for number of specific value appearances in django
I'm looking for a good example or advice to solve my problem in Django & python. I've simple model like Customer class Customer(models.Model): customer_name = models.CharField(max_length=500) CUSTOMER_CHOICES = [ ('pc', 'Private Customer'), ('bc', 'Business Customer'), ] customer_type = models.CharField(max_length=2, choices=CUSTOMER_CHOICES) For all customers, I want to build (and show on page) a specific "Customer Number" based on customer type and a decimal number. I think I might store this value in the Customer table (somethink like this): |id|customer_name|customer_type|customer_number| |1 |Private 1 |pc |1 | |2 |Private 2 |pc |2 | |3 |Business 1 |bc |1 | |4 |Private 3 |pc |3 | |5 |Business 2 |bc |2 | Of course, when I'll modify the customer name or other value (except customer type and customer number) I don't want to update this number. It is possible to avoid the number gaps or duplicate numbers? I think the bellow code will not work (this is just an example as first thought), because I don't know how the code will work when I'll have two different sessions and when I press the save button at the same time. def save(): if customer_number is None: last_number = Customer.objects.all().filter(customer_type=passed_type).last() #bellow in the pseudocode new_invoice_number = … -

How to use different key name in MongoDB while working with Django?
I am working on developing a micro service using Django, where I use MongoDB as backend. Folks who wrote the main code used java hence the data already present in the MongoDB collections follows camelcase pattern for e.g. firstName is the key name. Now while working with python I like to name my variables and functions using snake casing like first_name and get_first_name(). What I want is that inside the code I want to refer first name as first_name but while saving first name in DB or returning JSON response of user data I want to return it as firstName? Is there any way to achieve this behaviour? Please help me? -
