DjangoCMS - Admin Account Details
I took a break from working on a website I am currently building however I cannot for the life of me remember the admin account details.. I thought I could just create a new superuser however it appears the users for DjangoCMS and Django Admin may be different.. Does anyone know of a way to either reset the password or create a new user explicitly for DjangoCMS? I have attempted python3 manage.py createsuperuser however the user account created doesn't seem to work. Any help would be appreciated! There is very little on google about DjangoCMS.. -
How to update the value of nested dictionary and avoid bidding
When i update the value given specific keys in a nested dictionary, i seem to be binding the dictionnary to the value. This is a problem when i loop through a list of values as only the last value is saved. Instead i would like to only update the value given the relevant keys. In the code below, the last element of the list list will replace the value for all the dates for a given column_header: new_calendar = init_calendar(year,month,column_headers) for element in list: new_calendar[element.date][element.column_headers] = element init_calendar creates a nested dictionary where all dates for a given month have the dictionary {column_header1:None, column_header2: None, ...}. The for loop is meant to overrides the None value with an instance of object Element for a given date and column_header. list is a queryset of elements of class models.Element How could i update the new_calendar so that for a given instance element of the Element object, new_calendar[element.date][element.column_header] is updated with element ? Thank you -
Django filter many to many list of objects that contains all the items of a list
Models.py class Track(models.Model): title = models.CharField(max_length=300,null=True, blank=True) artists = models.ManyToManyField(Artist, related_name='track_related') artist_list = [mila, fuad, habib] I have to filter all the track that's artists contain all the artist from artist_list Mila, Fuad, and Habib I tried Track.objects.filter(artists__in=artist_list).annotate(num_artist=Count('artists')).filter(num_artist=len(artist_list)) But its not woking and also i think my logic isnt fully correct. -
Best practices in loading content into HTML
I am currently working on a project but haven't really done much on the frontend side. I have a relatively small dataset (around 130 rows, 7 field each). I am using Python backend to gather and manipulate the data. My question is how to load it into the HTML table. I have 2 ideas. 1st is to preload the table with data using Django, generate the HTML with all the data and then use JS to sort/filter/any manipulation regarding the content. 2nd one is to load all the data into a DB table, use JS to load it into HTML table. The data always comes from Python, preferably updated every half an hour or so. The JS will take care of the sorting/filtering functions. What is the best practice to load the data into the table? Thanks in advance! -
Committing save operations record by record inside threads in Django
My goal is to make Django save records to DB record by record inside a thread. My code looks like this: class MyThread(threading.Thread): def __init__(self, data, *args, **kwargs): self.data = data super(MyThread, self).__init__(*args, **kwargs) def run(self): for record in data: s = MySerializer(data=record) if s.is_valid(): s.save() # I want this record to appear in db at once I have ATOMIC_REQUESTS set to True inside settings.py. What I have tried to do is to include the s.save() command inside a transation like this: if s.is_valid(): with transaction.atomic: s.save() But it did not help. I wonder whether this is possible and isn't it an anti-pattern ? -

Adding multiple fields to SQLite3 in a single Django migration
I have a SQLite3 table with ~2 million rows and ~30 columns. I need to add 4 more fields to the model. I add new fields to models.py, run manage.py makemigrations and then manage.py migrate. When I check SQL queries, Django creates a new table (and drops the old one) for each new field instead of creating a new table once with all 4 fields added. This increases migration time 4 times which results in ~1 hour. Is it possible to optimize this somehow and force Django to add all 4 fields in a single CREATE TABLE statement? -

502 Bad Gateway, I messed up users and groups permissions on digitalocean ubuntu for django deployment
I have created a droplet, an ubuntu 18.04 server on digitalocen successfully. Followed the install digitalocean's guide and ran the gunicorn,nginx, django etc. and ran the website successfully on the browser using my ip address i.e. firewalls, gunicorn and nginx and everything were configured correctly. During the testing while uploading the images to the media folder I got an error "permissions denied" (POST error). Found somewhere the below code on google and thought it solves the permissions related problem: https://www.semicolonworld.com/question/55551/django-errno-13-permission-denied-39-var-www-media-animals-user-uploads-39 sudo groupadd varwwwusers sudo adduser www-data varwwwusers sudo chgrp -R varwwwusers /var/www/ sudo chmod -R 760 /var/www/ But the above code messed up everything and ran into "502 Bad Gateway". I am not very familiar with Linux deployments. Can someone help me investigating and resolving this issue. I think I have messed up the users, groups permissions. How can I get this resolved OR how can I revert what I did OR is there any activity logs I can see and investigate. Thanks for the help in advance. -

Facebook and Google Authentication process cancelled using Djoser in Django Rest framework with Next.js+React as frontend
I used Djoser to handle basic user authentication functions for me in Django Rest Framework. And I tried to use its social auth endpoint. According to its documentation, if I understand correctly, I first added redirect_uri to its endpoint, e.g. : http://127.0.0.1:8000/auth/o/facebook/?redirect_uri=http://localhost:3000 It worked fine. Then I used the link to authenticate and it returned code and state (as data in the code below) to me as queries in the redirect_uri. But then when I post back the code and state in getInitialProps method from Next.js server to my backend, const authResponse = await axios.post(`http://127.0.0.1:8000/user_info/o/facebook/`,data,{ headers:{ 'Content-Type':'application/x-www-form-urlencoded' } } Django returns a status code 400. Then I used postman to test posting code and state with 'Content-Type':'application/x-www-form-urlencoded', it showed on the window: { "non_field_errors": [ "Authentication process canceled" ] } I tried the same case with Google OAuth2. The following is the python code in my settings.py. import os from dotenv import load_dotenv load_dotenv() BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__))) DEBUG = True ALLOWED_HOSTS = ['127.0.0.1','0.0.0.0'] INSTALLED_APPS = [ ...
