Creating a multiple choice form for each primary key in model with Django
I am trying to create a class registration app in Django. To simplify my problem, I have a model for students, blocks (time periods), and classes (lessons).

I want to generate a form with radio buttons that looks like this: Block A (9:00 - 11:00) Django class for beginners Some other class Yet another class Block B (11:00 - 13:00) Class for something How to math Placeholder class ... Block E (16:00 - 17:30) Choice 1 Choice 2 Choice 3 Choice 4 Currently, my models look something like this: class Student(models.Model): first_name = models.CharField() [...] class Block(models.Model): block = models.CharField( primary_key=True, choices=(('A', 'Block A'), ('B', 'Block B'), ('C', 'Block C'), ('D', 'Block D'), ('E', 'Block E'))) start_time = models.DateTimeField() [...] class Class(models.Model): title = models.CharField() block = models.ForeignKey('Block') [...] So far, I have something like this in my forms.py: class ClassForm(Form): class_choice = ModelChoiceField( queryset=Class.objects.all(), widget=RadioSelect, empty_label=None) And I can serve that form in my views.py, … -

Django static css not loaded?
So my app has the following structure: base.html, which contains the nav and the links to the stylesheets and the home.html file, which loads the nav via extends. However, i can't really modify the css inside my home.html file, any suggestions whats wrong? base.html: {% load staticfiles %} <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>App</title> <link rel="shortcut icon" href="{% static 'img/favicon.png' %}"> <link rel="stylesheet" href="{% static 'css/app.css' %}"> ...## navbar etc. <div id="body"> <div class="container"> {% block page %} {% endblock %} </div> </div> home.html: {% extends 'base.html' %} {% load staticfiles %} {% block page %} <div class="row"> <div class="col-md-12"> <img src="{% static 'img/banner.gif'%}" class="banner"> </div> {% endblock %} As you can see in the base.html file, i load the app.css file via static method. However, changing for example the banner class in the home.html isn't working at all: #body .banner { width: 100%; margin-bottom: 150px; } No errors in the terminal / console.

Obtain the display value of a choice Field from a function within the own model

How create recursive loop for parsing the json?

AJAX Success Response Button Not Opening Modal
I'm creating an activity feed of communications, notes, and tasks. Each one has buttons for editing and deleting, which opens up a modal for either changing information or confirming the delete. The modals work fine. Once I load the data after a successful AJAX response, the buttons click (and the call is successfully made to the view) but the modal does not open. I've tried making the buttons "live" and appending the button, but the modal still won't open. This is the origin AJAX -- $(document).ready(function(){ $('.task_completed').click(function() { var id = $(this).attr('id'); var type_id = $('#contactID').attr('value'); $.ajax({ method: "POST", url: "{% url 'communications:task_completed_activity' %}", data: {'id': id, 'type': 'Contact', 'type_id': type_id}, beforeSend: function (xhr) { xhr.setRequestHeader("X-CSRFToken", '{{ csrf_token }}'); }, success: function(response) { $('.infinite-container').html(response); } }); }); }); This is an example of the modal that's failing to open -- $(document).ready(function(){ $(".task-delete").click(function(){ $("#taskDelete").modal(); }); }); This is the AJAX for the button -- $(document).ready(function(){ $('.task-delete').click(function() { var id = $(this).attr('id'); $.ajax({ method: "POST", url: "{% url 'communications:delete_confirm' %}", data: {'id': id, 'type': 'task'}, beforeSend: function (xhr) { xhr.setRequestHeader("X-CSRFToken", '{{ csrf_token }}'); }, success: function(response) { document.getElementById("task-object").innerHTML = response.object; document.getElementById("task-description").innerHTML = response.description; $('#task-id').val(response.id); } }); }); }); Let me know if … -

Validating a signed cookie set by Django in the browser
Django sets a signed cookie in the client's browser, and I have the following settings for managing cookie sessions: SESSION_ENGINE = 'django.contrib.sessions.backends.signed_cookies' SESSION_COOKIE_AGE = 86400 SESSION_SAVE_EVERY_REQUEST = False When I set the cookie value in the request headers and use this code to validate the cookie, I get this error message: raise BadSignature('Signature "%s" does not match' % sig) BadSignature: Signature "REDACTED"" does not match This is how I validate the signed cookie from the request payload (taken from the docs here https://docs.djangoproject.com/en/1.11/topics/signing/#using-the-low-level-api): cookie = '"blahhh:1redacted:redactedk"' from django.core.signing import Signer signer = Signer() signer.unsign(cookie) I even stripped out the " at the beginning and end of the cookie value, and that didn't work either.

python merge two query sets and addition of matching records
I have a need to merge two querysets together with simalar data. Set 1 (stats) has a list of teams, total points for that team and the division the team is in. Set 2 (spares) has a list of teams that have had a member spare for them which includes the teams and points (no division for this set). What I would like to do is merge the querysets into one and when the teams match, just add the spares points to the team total, keeping the team name and division. The code i am using below will sort of do what i am looking for except it does not include the teams that never had a spare on it. Consider the following data. Stats List Team 1 : 8 Points : Division A Team 2 : 3 Points : Division B Team 3 : 7 Points : Division A Team 4 : 5 Points : Division B Team 5 : 4 Points : Division A Spares List Team 1 : 3 points Team 3 : 6 Points So what I want to do is merge these two lists where the teams match but total their points.

What is the correct way to organize Django apps when serving data to multiple graphs?
I am currently working on a site that displays warehousing information, but am having trouble wrapping my head around Django's app concept when it applies to serving data for multiple pages of graphs. I currently have 3 apps: Authentication - handles registration pages and user profiles Notifications - manages alerts to the users when there are changes in the data Warehousing - all of the other data is served from here onto the templates The "warehousing" app has grown way too large, since it provides data for the rest of the site (4 different templates), each of which has several graphs and also includes a map of warehouse locations and a log of warehousing equipment. I understand that each Django app is supposed to have a single focus, but what is the proper way to structure them when dealing with an application like this where a majority of the site is pages of interactive graphs?
