Django - Making a Reservation system
As a part of a task, I created an "apartment listings" website. I managed to get that done, but now I need to make a "reservation system" for it. The basic idea is that a logged in user can select an apartment from the listed apartments, pick a "start_date" and an "end_date" and (if the apartment already isn't booked ) and book the apartment. Im a total Django newbie, and need some pointers in order to start somewhere with this task. I have an Apartment model which contains all of the Apartments info that I use to print everything out with the template. I'm using the provided django user models to register / log-in. What kind of model do I need for the reservation, and how could I connect everything ? I tried making a reservation model, but I got no idea where to go next. I'm not asking for you to solve this for me, I'm asking for someone to explain (if possibile in detal) to me how could I go on about achieving this on my own. this is my apartment model: class Apartment(models.Model): title = models.CharField(max_length=200) address = models.CharField(max_length=200) city = models.CharField(max_length=100) state = models.CharField(max_length=100) zipcode = … -

django google_cloud_logging json format
I am trying to use google_cloud_logging with Django to log JSON logs to Stackdriver. However, the received format on Stackdriver is not as I would expect. My settings.py LOGGING setup looks like: LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'handlers': { 'console': { 'class': 'logging.StreamHandler', }, 'stackdriver_logging': { 'class': 'google.cloud.logging.handlers.CloudLoggingHandler', 'client': log_client, }, }, 'loggers': { '': { 'handlers': ['console', 'stackdriver_logging'], 'level': 'INFO', 'propagate': True, }, 'django': { 'handlers': ['console', 'stackdriver_logging'], 'level': 'INFO', 'propagate': True } } and I write dictionary logs like: _logger.info({'message_type':'profile', 'runtime': 500}) I would expect on Stackdriver for messages to appear as: { ... jsonPayload:{ 'message_type':'profile', 'runtime': 500 } } However they appear with the following format: { ... jsonPayload:{ 'message': "{'message_type':'profile','runtime': 500}" } } where instead of the jsonPayload being directly the sent dictionary, it is string encoded in 'message'. It's unclear what I should change in order to have the desired format on Stackdriver. Could anyone point me in the right direction? -

getting only the date on datetime
Good day! I'm new in using Django and python and I wanted to check only the date in DateTime inside my database. model = Employee_Salary Employee_Salary.objects.filter(emp_id=employee_id, emp_in=datetime.today().date()).exists() so the code I'm currently using is this datetime.today().date() to get only the date if Employee_Salary.objects.filter(emp_id=employee_id, emp_in=datetime.today().date()).exists(): # if emp out exist then stop if Employee_Salary.objects.filter(emp_id=employee_id, emp_out=datetime.today().date()).exists(): messages.info(request,'you are already logged out...') return render(request, 'registration/register.html', locals()) else: Employee_Salary.objects.filter(emp_id=employee_id).update(emp_out=datetime.today()) # should be emp out, rendered and salary messages.info(request,'logged out...') return render(request, 'registration/register.html', locals()) else: #command if employee does not exist add employee register_emp = Employee_Salary(emp_id=employee_id, emp_in=datetime.today()) register_emp.save() messages.info(request,'logged in') return render(request, 'registration/register.html', locals()) #this is my entire code I expected it to check my model Employee_salary's emp_in, which emp_in is a DateTime, then I wanted to check only the date and if there is a date already this day, it will now put a data inside the emp_out instead, but it didn't happen, it made another login of emp_in instead... I really hope I explained it well and thanks in advance on your help! -

How do I use a jQuery gallery (fotorama) in my Django project?
I've created a page in Django which serves images of a specific car into a gallery slider like this My problem is that it's not even recognizing the fotorama gallery.

Proper implementation of Django model inheritance architecture?
I'm building simple Django app for reviews of diffrent objects (restaurants, car services, car wash etc), so I started with the app, but soon I faced first problem, every object have features (but every type of object have different features), for example restaurants have (garden, playground, seats etc, type of kitchen), car washes have (external cleaning, internal cleaning etc). So I started to build typical DB implementation with ManyToMany tables, but then I found Django Model Inheritance, so I implement it in my APP, as you can see: urls.py: from django.urls import path from . import views urlpatterns = [ path('user/<int:pk>/', views.UserObjectsView.as_view(), name='user-objects'), path('add/', views.add_object, name='add-object'), path('<str:category>/<int:pk>/', views.show_object, name='show-object'), path('all/<str:category>/', views.show_all_objects, name="show-all-objects"), ] models.py: from django.db import models from users.models import ProfileUser from django.utils import timezone # Create your models here. class Object(models.Model): author = models.ForeignKey(ProfileUser, on_delete=models.CASCADE) title = models.CharField(max_length=300) address = models.CharField(max_length=300) content = models.TextField() created_date = models.DateTimeField(default=timezone.now) approved_object = models.BooleanField(default=False) admin_seen = models.BooleanField(default=False) def __str__(self): return f"{self.title}" class Restaurant(Object): seats = models.IntegerField() bulgarian_kitchen = models.BooleanField(default=False) italian_kitchen = models.BooleanField(default=False) french_kitchen = models.BooleanField(default=False) is_garden = models.BooleanField(default=False) is_playground = models.BooleanField(default=False) class SportFitness(Object): is_fitness_trainer = models.BooleanField(default=False) class CarService(Object): is_parts_clients = models.BooleanField(default=False) class BeautySalon(Object): is_hair_salon = models.BooleanField(default=False) is_laser_epilation = models.BooleanField(default=False) class FastFood(Object): is_pizza … -
