Can you containerize different django applications belonging to a single project in different docker containers?
So basically, I have three different modules or apps in a single django project - These are registration application (registers the user), login application (login), status application (retrieves the data and displays the currently online users). I use redirects to redirect from one template to another such that the registration page will redirect to the login html page and so on. I have kept all the html files in a template folder. I have a common project for all these applications. I want to containerize each of these applications in to a single container, such that I would have three different containers but I am having troubles in understanding how the redirects would work? As these applications are interacting with each other, how would I be doing this? I would implement the databae on AWS or GCloud. -

VScode autocomplete not working after using sshfs to mount a directory inside the workspace
I’m using VScode to develop a Django web application on the next environment: • OS and Version: Windows 10 • VS Code Version: 1.52.2 • Python Extension Version: v2021.5.842923320 • Remote – SSH Version: v0.65.4 From my Windows laptop, I work on an Ubuntu 20.04 VM using the Remote – SSH plugin, So I have configured a python3.9 virtual environment with Django3.2 and others python packages. Also, I have pylint installed and all works as expected. The issue arises when I mount a folder inside the application media folder (inside the workspace) from another station through sshfs. What happens is that autocomplete stops working and when y press Clr+Space I just get a loading message. Note that this folder that I mount through sshfs is very big more than 1 TB with many files including python scripts and also I note that even when I close the VScode I cannot unmount this folder because the fusermount said that the folder is used by some process (I guess is the VScode process inside the VM). After all, if I don’t open the VScode I'm able to mount and unmount this folder without a problem. I have also excluded this media folder … -

Django forms with CSRF protection in IOS 14+
IOS 14 came out few months ago, which defaults to blocking all third party cookies unless the user enables them specifically by disabling this option: Settings -> Safari -> Prevent Cross-site Tracking This presents a problem for Django forms with csrf protection that is served inside an <iframe> from a third-party domain like this: -----Parent website----- | | | ----------------- | | | | | | | Django form | | | | inside | | | | iframe | | | | | | | ----------------- | | | ------------------------- Django form sets a csrfmiddlewaretoken as a hidden form variable and also sets a cookie called csrftoken, and does the form security verification when the form is submitted. The problem comes when attempting to set the cookie csrftoken while inside an <iframe>, being in a third-party website context. In IOS 14, this cookie is rejected. The form still submits without this cookie but django rejects the form as expected. The exact error I am getting: Forbidden (CSRF cookie not set.), which is correct from django's point of view. The form works correctly when we disable the Safari setting, to allow cross-site tracking. But this needs to be done at … -

pymemcache with pickle django
I was trying to cache a Django model Instance like class MyModel(models.Model): ... several atributes, as well as foreign key attributes ... from pymemcache.client import base import pickle obj = MyModel.objects.first() client = base.Client(("my-cache.pnpnqe.0001.usw2.cache.amazonaws.com", 11211)) client.set("my-key", pickle.dumps(obj), 1000) # 1000 seconds # and to access I use obj = pickle.loads(client.get("my-key")) They both works fine, but sometimes executing the same line: client.get("my-key") generates very very strange errors like Traceback (most recent call last): File "/opt/python/current/app/proj/utils/Cache.py", line 93, in get_value return Cache.client.get(key, None) File "/opt/python/run/venv/local/lib/python3.6/site-packages/pymemcache/client/base.py", line 481, in get return self._fetch_cmd(b'get', [key], False).get(key, default) File "/opt/python/run/venv/local/lib/python3.6/site-packages/pymemcache/client/base.py", line 823, in _fetch_cmd prefixed_keys) File "/opt/python/run/venv/local/lib/python3.6/site-packages/pymemcache/client/base.py", line 791, in _extract_value key = remapped_keys[key] KeyError: b'some-other-cache-key' and sometimes I get: Traceback (most recent call last): File "/opt/python/current/app/proj/utils/Cache.py", line 93, in get_value return Cache.client.get(key, None) File "/opt/python/run/venv/local/lib/python3.6/site-packages/pymemcache/client/base.py", line 481, in get return self._fetch_cmd(b'get', [key], False).get(key, default) File "/opt/python/run/venv/local/lib/python3.6/site-packages/pymemcache/client/base.py", line 833, in _fetch_cmd raise MemcacheUnknownError(line[:32]) and sometimes I get Traceback (most recent call last): File "/opt/python/current/app/proj/utils/Cache.py", line 93, in get_value return Cache.client.get(key, None) File "/opt/python/run/venv/local/lib/python3.6/site-packages/pymemcache/client/base.py", line 481, in get return self._fetch_cmd(b'get', [key], False).get(key, default) File "/opt/python/run/venv/local/lib/python3.6/site-packages/pymemcache/client/base.py", line 823, in _fetch_cmd prefixed_keys) File "/opt/python/run/venv/local/lib/python3.6/site-packages/pymemcache/client/base.py", line 790, in _extract_value buf, value = _readvalue(self.sock, buf, int(size)) File "/opt/python/run/venv/local/lib/python3.6/site-packages/pymemcache/client/base.py", line 1234, in … -
Assigning same integer to specific string for table in database
I'm gathering errors to the table SystemErrors which now looks like this id error_msg system_id 1 error1 1123 2 error1 341 3 error2 1415 The message of errors though is too long, so i need another column to the later verification which error it is. And i want in the same table another column which will be connected with Error column. If the row with error1 is added, i want column error_id with integer 1. Like this id error_msg error_id system_id 1 error1 1 38 2 error1 1 112 3 error2 2 323 Now my code looks like this class SystemError(models.Model): report = models.ForeignKey(SystemReport, on_delete=models.CASCADE) error_msg = models.CharField(max_length=2000) Can i do this in this table by assigning any connection with error_msg
