get user group name from a specific text in django
In django, user posts in a simple HTML form. In form, there is a field which called "technician_name". I'm getting the post with "name attribute" and write it to database. I want additional thing: after I take the name attribute, I want to check the group of technician. Simply: I want to check user's group according to specific text. For example: user posted the "John Doe". if request.method == 'POST' action_man = request.POST.get('technician_name') Output: action_man = "John Doe" I need this action_man's user group. The action_man's name same with username, so I can query in django auth. Note: I don't need the logged in user's group. I need action man's group. -
Avoid CSRF_TRUSTED_ORIGINS in Django 4.1
I've a dockerized Django project which I access through NGINX. I just upgraded to Django 4.1 and now it seems that it's mandatory to define a CSRF_TRUSTED_ORIGINS listing, I would like to know if there is a way to allow POST requests from any source. I've tried installing https://github.com/ottoyiu/django-cors-headers and setting CORS_ALLOW_ALL_ORIGINS to TRUE but it didn't work :/ Also I tried setting CSRF_TRUSTED_ORIGINS = ['*'] as I have in ALLOWED_HOSTS but it doesn't work... Thank you so much! -

Level of logger in django project app view is undefined
When i initialize the logger in the views.py of my app in my django project, the loglevel is undefined althoug i defined it as INFO in the settings.py. I pass the loglevel as a environment variable (I also checked that it is correctly set to INFO by debugging it). When I check the level of the logger in the views.py it always is 0 which means undefined. I also tried to add a root block to the settings and change the name variable to "django" to load the logger both didn't worked. Maybe anyone can tell me what I am missing?

Why isinstance(Test(), MyAbstractClass) return False even if I implement all abstract methods in Test class
From some book, it says when we define a class and implement all abstract methods, even if the class is not inherited from abstract class, the isinstance() check will return True. I try it on my local: from collections import abc class Test: def __len__(self): return 0 print(isinstance(Test(), abc.Sized)) Because there is only one abstract method in abc.Sized class:_len_, the output is True as expected. But when I try to define my own abstract class, it fails: from abc import abstractmethod, ABCMeta Class MyAbstractClass(metaclass=ABCMeta): @abstractmethod def get_size(self):pass class Test: def get_size(self): return 0 print(isinstance(Test(), MyAbstractClass)) The output is False. I need to register it if I want it to be True: MyAbstractClass.register(Test) Why? Why I check it with abs.Sized I don't need to register it but with my own defined abstract class, I have to register it? -
User Roles In Django
I was able to build a Web app that can restrict access to certain pages for authenticated using Django permissionmixedin But I want to divide authenticated users into groups that can be able to access only certain pages. That is even if you are authenticated you can't access all the pages, but can only access the pages that your group fall into. I thought I could set that up when I log into Django admin panel as a super user, but it did not work. Please I need a comprehensive guide on how to do that, both on the user model, views.py and any other file. Because am completely new to this. Am using class based views because am not conversant with function based views. -

By analogy with the pseudopotential approach for electron-ion interactions, an effective electron-electron interaction is developed which closely reproduces the scattering of the Coulomb interaction but is smooth and finite at zero electron-electron separation. The exact many-electron wave function for this smooth effective interaction has no cusp at zero electron-electron separation. We perform CI and quantum Monte Carlo calculations for He and Be atoms, both with the Coulomb electron-electron interaction and with the smooth effective electron-electron interaction. We find that convergence of the CI expansion … -

Python - check if condition is met within a given timeout
I've a script that 1. downloads & push binaries to internal registry (func_to_push_image) and 2. process messages from a section of messaging queue, to see if the push is successful by filtering the messages for a keyword 3. If the push is successful, monitor and process another section of messaging queue, to validate whether those two binaries are installed by looking at the install_status keyword. Timeout for the push action is 2 mins, else fail the script immediately. Timeout for the install action is 1 min, else fail the script with timeout.

Hide Unsupported operand type(s) for -: 'int' and 'NoneType' when no data in database
I am having this issue where I get this error unless there are at least 2 lines of data in the database. Basically what I am doing is marking an item as refunded. I will aggregate all of the fields and then do the math. If I do not have at least 2 lines of data in the database, I always get this error. unsupported operand type(s) for -: 'int' and 'NoneType' The specific line is throwing the error is: total_partial = 0 - total_p_r['refund_amount__sum'] I am not understanding why I am getting NoneType when the default is set to zero on all lines of the models.

Label with text copy functionality creation in tkinter
I've got the following tkinter classes that give copy/paste functionality to Entries and copy functionality to Labels. However, I'm not sure how to get the CPLabel class to retrieve the text from the text parameter. When I run the program as is, the CPLabel is packed as evidenced by a space where it should appear, however, no text shows. class CPEntry(Entry): def __init__(self, *args, **kwargs): Entry.__init__(self, *args, **kwargs) self.bind('<Control-c>', self.copy) self.bind('<Control-v>', self.paste) def copy(self, event): self.clipboard_clear() selected_text = self.selection_get() self.clipboard_append(selected_text) def paste(self, event): self.delete(0, END) pasted_text = self.clipboard_get() self.insert(0, pasted_text) class CPLabel(CPEntry): def __init__(self, *args, **kwargs): CPEntry.__init__(self, *args, **kwargs) self.configure(state="readonly", highlightthickness=0, bd=0, cursor="arrow", textvariable=None) self.insert(0, kwargs.get('text', '')) The text that should be displayed is what is within the text parameter. For example, the CPLabel below should display 'Enter a prime number for the value of p'. pLabel = CPLabel(root, text = 'Enter a prime number for the value of p') If you could let me know what I'm doing wrong, or how to get this to work properly that would be awesome.

How to create a stub Python package for PyCharm?
Let's say we have a builtin module car. We have no autocomplete in PyCharm for it. It has interface: def getState(id, optional_id = None): pass def log(value): pass So, end usage would be: import car car.getState(5) car.log('Test') How to create a package and join it into PyCharm to make autocomplete work for a described interface? If I created a package car-stub with car.py file, and installed it in the project, I will have to use code line from car-stub import car. But how to make it in such a way it would not require code changes? The system would provide autocomplete for import car.
