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. The <div class="fotorama"></div> shows up in the inspect code, but the images are still spread out in html's default layout. Jquery isn't linked because I've linked to it in the base.html file for bootstrap, so I know it works. I'm hosting the fotorama.js and .css locally since they didn't work when served via CDN. Yes, I've already run collectstatic. <head> ... {% load static %} <link href="{% static 'css/fotorama.css' %}" rel="stylesheet"> <script src="{% static 'js/fotorama.js' %}"></script> </head> ... <div class="container"> <div class="row"> <div class="col justify-content-center"> <div class="fotorama"> <img src="/static/images/placeholder.jpg"> {% for image in car.image_set.all %} <img src="{{ image.image.url }}"> {% endfor %} </div> </div> </div> </div> Just as a quick test, I served a normal image outside of all the other container, row, and col divs. It also didn't make a difference. <div class="fotorama"> <img src="/static/images/placeholder.jpg"> </div> This is what the page looks like: I made a quick page outside my django project, and fotorama works perfectly. Could this be a django-specific issue? Is there an extra plugin/extra code I … -
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 … -

URLConnection hits server twice when downloading file?
After reading HttpURLConnection request being hit twice to the server for downloading file it was very similar and helped, but I still see my server gets two requests for a single download. This is my AsyncTask that I use to download a file from a Django web server. @Override protected String doInBackground(String... sUrl) { String path = "/sdcard/YourApp.apk"; try { URL url = new URL(sUrl[0]); HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection(); urlConnection.addRequestProperty("Authorization", "Token " + authToken); urlConnection.connect(); int fileLength = urlConnection.getContentLength(); // download the file InputStream input = new BufferedInputStream(urlConnection.getInputStream());//url.openStream()); OutputStream output = new FileOutputStream(path); byte data[] = new byte[1024]; long total = 0; int count; while ((count = input.read(data)) != -1) { total += count; //publishProgress((int) (total * 100 / fileLength)); output.write(data, 0, count); } output.flush(); output.close(); input.close(); urlConnection.disconnect(); } catch (Exception e) { Log.e("SVC0", e.getMessage()); } return path; } Then I look at the Django logs and I can see that two requests are present: [09/Oct/2019 02:30:29] "GET /update HTTP/1.1" 301 0 [09/Oct/2019 02:30:35] "GET /update/ HTTP/1.1" 200 19451876 I have tried commenting out many parts but I just can't figure out why it's causing the 301 error.

How to send dictionary data with redirect function in Django

Noob Django question: When do I make an app vs coding something for the whole website?
I want to implement things like user logins for the entire website and not within a specific app. Can someone point me in the right direction/some reference I can look up? I've looked at tutorials for the login, and they all refer to building logins within an app, not the main website. Should I build a "Welcome" or "Registration" app, and then import it into every other app? -
API response time is too slow using DRF
Activity is tourist information and tag (Preference) is tag information (such as Instagram hash tag). Function of Activity ListPreference api: For every activity, check that each activity contains tags from the request list. Only the activities that contain the tags are serialized. But it's too slow.

How to execute custom SQL query when deleting a model item in Django?

Rename Django User fields
I'm using the default Django User class and authentication for a simple user LogIn. This User model has two important fields: "username" and "password". I want them to be "user" instead of "username", and "pass" instead of "password". I know I can make a RenameField, but that will only change the column name in the database, it won't change how Django asks for the username and password in the body of the POST request. I need to change the keys in the JSON given in the request. from: { "username": "user123", "password": "pass123" } to: { "user": "user123", "pass": "pass123" } And I think I can create a file called serializer and do something there but I'm not sure how, and I didn't found anything in the documentation.
