Regroup in django returning only one grouper - not iterating on regrouped list
I have a simple ListView of a Model with a DateTimeField, the Model is ordered by this field. In the template, I have the following code: {% regroup teamsession_list by tdate|date:"W" as weekly_list %} {% for training_week in weekly_list %} <div class="container"> {{training_week}}</div>{% endfor %} I wrote this to test the returned result. I have four weeks of data, but only one grouper returned in the template like so GroupedResult(grouper='48', list=[<TeamSession: xesr: performed on 2018-11-27 00:00:00+00:00>, <TeamSession: test4: performed on 2018-11-26 00:00:00+00:00>, <TeamSession: test5: performed on 2018-11-26 00:00:00+00:00>, <TeamSession: test: performed on 2018-11-26 00:00:00+00:00>]) Anyone with an idea why the other four week is not in the result? The view looks like this: class TeamWeeklyView(ListView): model=models.TeamSession template_name = 'teams/weekly.html' I know there is a weekly archive view, but its not suitable for my purposes. -

Django radio form showing ['on'] for the POST values
When I working with Django forms, I need to get the selected radio button id on submit.

ValueError - Python Django
I went through forums and did some changes in my codes but the problem is still there. I did migrate and makemigrations, and even deleted migrate and recreate it again. I also added default=0 to the models.py code: age = models.PositiveIntegerField(default=0) I'll appreciate you if you help me on this issue.

List Django database table names from external script
I am trying to access sqlite3 database that I have in my Django project from within external script that is not part of the project. However, the following will return an empty list: con = sqlite3.connect('database.db') cursor = con.cursor() cursor.execute("SELECT name FROM sqlite_master WHERE type='table';") print(cursor.fetchall()) Even though I have already saved some models to the database. To check the table names, I use the following in Django shell: >>> tables = connection.introspection.table_names() >>> seen_models = connection.introspection.installed_models(tables) >>> seen_models {<class 'django.contrib.auth.models.Permission'>, <class 'django.contrib.sessions.models.Session'>, <class 'django.contrib.contenttypes.models.ContentType'>, <class 'explorer_api.models.Athlete'>, <class 'django.contrib.admin.models.LogEntry'>, <class 'django.contrib.auth.models.Group'>, <class 'explorer_api.models.Activity'>, <class 'django.contrib.auth.models.User'>} >>> tables ['auth_group', 'auth_group_permissions', 'auth_permission', 'auth_user', 'auth_user_groups', 'auth_user_user_permissions', 'django_admin_log', 'django_content_type', 'django_migrations', 'django_session', 'explorer_api_activity', 'explorer_api_athlete'] I have specified the table names explicitly in model's Meta, so I guess the table names are appname_modelname (explorer_api_activity and explorer_api_athlete). But why the empty list? -
Passing default paramter value to view method in django is not working
I am very new to Django. I am trying to use an URL with optional parameter, If I pass an URL including the optional Parameter, everything works as expected, but when I try to use an URL without the optional parameter I am getting a 404 page not found error.

I am using Django 1.11, I am not sure if there is anything related to the version of Django. -

Creating A Timer For an Academic Quiz
I am creating a web app that's supposed to ask 90 questions in 180 mins. The backend uses Django, while the frontend uses the trio of HTML, CSS and Jquery, Javascript. I've managed to implement the display and entering the questions part. However I'm having issues implenting the timer part. Specifically, I've no idea what should I use to create the timer, the backend or the frontend. Also how to implement it? Thanks! -
Django 2.1 passing a variable to template,
Have a question here about passing a variable into a Django template. The goal is to filter a set of photos based off the type of photography. I initially wanted to do it from S3 and the folder that it was in, but that's a little beyond my skill at the moment. I went with just creating different url's that account for that. The issue I'm having is that I'd like to pass the variable into the template that extends the base_layout.html, but it won't render anything for that variable. Am I just miss-understanding how to do it? Model.py from django.db import models # Create your models here. class Gallery(models.Model): title = models.CharField(max_length = 50) body = models.TextField(max_length = 500) created = models.DateTimeField(auto_now_add = True) thumb = models.ImageField(default = 'default.jpg', blank = True) slug = models.SlugField(blank = True) order = models.CharField(max_length = 2, blank = True) def __str__(self): return self.title def body_preview(self): return self.body[:50] class photoUrl(models.Model): url = models.CharField(max_length = 128) uploaded_on = models.DateTimeField(auto_now_add = True) class Photos(models.Model): title = models.CharField(max_length = 50) picture = models.ImageField(blank = True) created = models.DateTimeField(auto_now_add = True) catagory = models.CharField(max_length=256, choices=[('wedding', 'wedding'), ('portrait', 'portrait'), ('landscape', 'landscape'), ('boudoir', 'boudoir'),], blank = True) def __str__(self): return … -
Saving an unknown object type into database in Django
I have the following model: class Parameter(models.Model): par_type = = models.CharField(max_length=30) value = models.TextField() Majority of the time the value field will store a number (value=3.2118). But sometimes I want to assign a list of other object IDs (like value="[32, 22, 45]") or a string object (like value="pass"), etc. I will use value field in functions like the ones below based on the value of par_type: def foo(par): # par is a Parameter object. return float(par.value) / 2 def bar(par): # Some code to convert a par to a list of objects object_list = get_objects(par) # Return a random object from list return random.choice(object_list) I don't want to write a piece of code for every possible object type. Ideally there is one decompose() function to use everywhere. I thought of saving object as pickle or JSON type (saw it from here). But I couldn't figured out how to do it. I'm using MySQL db. -

Django: Displaying appointment linked to a particular user on their profile only
I have a model in Django called 'Booking' to book appointments, where there are two user fields: an expert, and a user which both have ForeignKey relationships. I also have a CustomUser model and each user has a profile page. How can I specify that I want to view only the appointments linked to that particular user (or expert) on their profile page? models.py: class Booking(models.Model): user = models.ForeignKey(CustomUser, null=True, default='', on_delete=models.CASCADE) expert = models.ForeignKey(CustomUser, null=True, default='',on_delete=models.CASCADE, related_name='bookings') title = models.CharField(max_length=200, default='Video call with ..', null=True) start_time = models.DateTimeField('Start time') end_time = models.DateTimeField('End time') notes = models.TextField('Notes', help_text='Please provide some detail on what you would like to learn or discuss', blank=True, null=True) views.py: class BookingView(CreateView): model = Booking form_class = BookingForm def view_profile(request, pk=None): if pk: user = CustomUser.objects.get(pk=pk) else: user = request.user args = {'user': user} return render(request, 'profile.html', args) The profile displays all of the user objects fine, but I'm not sure how to call the user-linked booking objects only on the profile page. Any help would be appreciated!! -
Django Database Settings Reading From Base File
I have my Django application configured to use sqlite in the base settings file and I overwrite the setting in the production and development settings files. I set DJANGO_SETTINGS_MODULE to the correct value in my Dockerfile. However, when I run it, it uses sqlite as defined in the base settings file. If I comment it out I it complains about database.ENGINE not being set. Why is it reading the database configuration from the base.py settings file rather than the other? I specify the other in the environment variable and it's reading other settings from there but for the database it reads it from the base file. I'm somewhat confused by this behavior, if anyone could give me some direction towards solving this issue it would be appreciated. If you need any more information let me know. -

in my django-admin detail i have two select fields (foreign keys): Via the first one i can select a Customer (object) Via the second one i can select a CustomerAddress (object) When i select the Customer A, i only want to present customer addresses which belong to this specific Customer A. When i select the Customer B, i only want to present customer addresses which belong to this specific Customer B. But django-admin loads all customer_addresses into the second select field. How can i make these two fields dependent on each other? thanks and greetings! -
Djano - right way to join not-django tables
I have old cms database, structure isn't perfect and it can't be modified but i need to query using django TABLE posts (post_id) TABLE posts_text (post_id, post_text) TABLE episode (id, season_id, episode_name) TABLE episode_post_relationship (id, season_id, episode_id, post_id) Please help me to create django models with right fields reference. Should i use OneToOneField, ForeignKey, ManyToManyField and etc or pure join? I'm trying to get Episodes from episode_post_relationship table with posts_text.posts_text and posts.some_other_col but can't specify that episode_post_relationship table should join posts_text on post_id and the same for posts table.
