Use Traefik reverse-proxy to host WordPress and Django
I am new to deployment related tasks so what I'm asking may be very simple to implement but it is difficult for me nonetheless. In one domain, I need a WordPress-based public website (about 3-4 pages) as well as a link to log into the internal management Django v3.2 app. Both plus some extras (redis, postgres) will be served through docker-compose. I am using cookiecutter-django for my Django application. It uses Traefik by default as reverse-proxy for the production configuration. I looked at the docs for Traefik and I couldn't quite understand how I can implement the paths for my use case. I have the WP site and the Django app separately working currently so I just need to figure out how to deploy it together under the same domain, just different paths. As an example of what I need to achieve, let's assume my WordPress site has pages home, about, and contact so I would want the full URL to be example.com, example.com/about, and example.com/contact respectively. Any other links should be forwarded to Django. For those who have not used cookiecutter-django, the default file structure and configuration is to have a separate traefik.yml and Dockerfile for Traefik, and separate … -
APS Scheduler raising exception for no reason django

AttributeError: module 'crontab' has no attribute 'CronSlices'
I am currently dev a website using Django. I want to program tasks so I am planing to use Celery and Redis. I've installed Celery (pip command). I've also installed Redis using brew and it works : redis-cli ping returns PONG. I had to install django-celery-result and django-celery-beat (I used pip command). After setting-up my Django code, I got this error message when I run the server. File "/usr/local/lib/python3.9/site-packages/django_celery_beat/validators.py", line 7, in <module> class _CronSlices(crontab.CronSlices): AttributeError: module 'crontab' has no attribute 'CronSlices' I didn't know how to fix this error. Do anyone has an idea of where the problem comes from ? Thx -

In Django models, how does the foreign key field know which field to match with in the other model?
I understand what Foreign Keys do but I'm having trouble understanding why this is working in Django. I have the Project model in 'app1/models.py' file. This model has a ForeignKey named 'owner' that links to the Profile model in my 'app2/models.py' file. How does the 'owner' field in the Project model know it should be linking to the 'user' field in the Profile model if I'm only passing the model name to the 'owner' field? I feel like I should be passing the Profile.field or something like this in the Project model: owner = models.ForeignKey(Profile.user, null=True, blank=True ... ) Full model code from Dennis Ivy's tutorial: class Project(models.Model): owner = models.ForeignKey(Profile, null=True, blank=True, on_delete=models.SET_NULL) title = models.CharField(max_length=200) #null is default=False and is required description = models.TextField(null=True, blank=True) #for a bigger field, allows null(for db)/blank(for Django get/post) featured_image = models.ImageField(null=True, blank=True, default='default.jpg') demo_link = models.CharField(max_length=2000) source_link = models.CharField(max_length=2000, null=True, blank=True) #can be blank in db tags = models.ManyToManyField('Tag', blank=True) #quotes will ref other class after this one vote_total = models.IntegerField(default=0, null=True, blank=True) vote_ratio = models.IntegerField(default=0, null=True, blank=True) created = models.DateTimeField(auto_now_add=True) #generate when model instance is created id = models.UUIDField(default=uuid.uuid4, unique=True, primary_key=True, editable=False) class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, null=True, blank=True) name … -

Django ListView Through Model Relationships
I have been reading through here and I can't seem to find the answer of the question I am looking for. Maybe I'm not asking the correct question. I have three models. Recruiter Office Recruit Recruiters are assigned to multiple offices and each office has multiple employees. What I need to be able to do is create a listview that lists all of the employees that are associated with a recruiter. So something like this: Recruiter 1 has Office 1 and 2 assigned to them. Office 1 has Employee 1,2,3. Office 2 has employee 3,4,5 The Listview should display all employees under Recruiter 1. My Models are: class Recruit(models.Model): id = models.CharField(max_length=25,primary_key=True, unique=True) first_name = models.CharField(max_length=50) last_name = models.CharField(max_length=50) mobile_phone = models.CharField(max_length=20,null=True) preferred_phone = models.CharField(max_length=20,null=True) email= models.CharField(max_length=100,null=True) officeid = models.ForeignKey(Office,on_delete=models.DO_NOTHING,related_name="recruit") class Office(models.Model): office_name = models.CharField(max_length=100) officeid = models.CharField(max_length=20,primary_key=True,unique=True) class Recruiter(models.Model): user = models.OneToOneField(User, related_name='recruiter',on_delete=models.CASCADE) organization = models.ForeignKey(UserProfile,on_delete=models.CASCADE) Do I need a AssingedOffices table to join this all together? class AssignedOffice(models.Model): user = models.ForeignKey(UserProfile,on_delete=models.CASCADE) esa_office = models.ForeignKey(Office,on_delete=models.CASCADE) Just not sure how to connect them & display in the listview. -

And I successfully created a list But exclude is not working in list for exclude true Booleans models.py class Profile (models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) name = models.CharField(max_length=30) first_boolean = models.BooleanField(default=False) second_boolean = models.BooleanField(default=False) third_boolean = models.BooleanField(default=False) views.py def page(request): Booleans_List = [] Booleans_Lista.append(request.user.profile.first_boolean) Booleans_Lista.append(request.user.profile.second_boolean) Booleans_Lista.append(request.user.profile.third_boolean) context = {'Booleans_List'} return render(request, 'page.html', context) This List is working Fine, But I am trying to exclude Booleans which are true and also I am trying use .first() in list. But I have no idea, how can I do it. Any help would be greatly Appreciated. Thank You in Advance -
Tastypie: The format indicated had no available deserialization method
I'm trying to send some zip files and some json data to a tastypie endpoint.

Django: It takes time for order_by() and count()
The following model object has about 300k rows in postgres, and I have set db_index=True for the published_at field. For some reason, order_by() takes a long time. (+100ms or so) Also, .count() takes a long time. (about 150ms). Why do these take so long even though the index is specified? class Video(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) title = models.CharField(max_length=300) thumbnail_url = models.URLField(max_length=1000) preview_url = models.URLField(max_length=1000, blank=True, null=True) embed_url = models.URLField(max_length=1000) embed_source = models.ForeignKey(EmbedSource, on_delete=models.CASCADE) duration = models.CharField(max_length=8) tags = models.ManyToManyField(Tag, blank=True, db_index=True) views = models.PositiveIntegerField(default=0, db_index=True) is_public = models.BooleanField(default=True) published_at = models.DateTimeField(default=timezone.now, db_index=True) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) class Meta: ordering = ["-published_at"] def __str__(self): return self.title -
How to change the starting auto-generated-primary key id in a Django + PostgreSQL web application?
I have a web application build on Django using PostgreSQL database. In a few tables, I have auto-generated-IDs being used as primary keys. Due to some unexpected circumstances, I had to uninstall everything on the Linux server and again setup them on a different Linux server. I want to use all the data which I had stored earlier and taken dumps in csv files for each table before uninstalling. So, I've used copy function and and copied all columns data (including "id") into the new database. Now, when using the Django app which is trying to insert data into the tables, its throwing PRIMARY KEY ERROR saying that id already exists. So, what can I do now so that this Django+PSQL app uses id from some 1000 or 5000 rather than from 1 since the previous ones are already used? How to know this setup not to use 1 to 1000 as its already used. I don't think any screenshots are required for this. Kindly let me know if I have to make myself more clear. Thanks much in advance.
