Should a shopping cart id be tied to a user id?
I want to create a shopping cart app that is tied to the user id. Mainly because if the user logs out, the items in the cart won't be deleted. This is my first Django project so I'm not 100% sure if this is a good idea as the tutorials I'm following all use sessions for the carts, so it would be great if someone could give me some feedback. Here is my models.py: from django.db import models from django.conf import settings from menulistapp.models import menulist User = settings.AUTH_USER_MODEL class CartManager(models.Manager): def new_or_get(self, request): try: cart_obj = Cart.objects.get(id=request.user.id) new_obj = False except Cart.DoesNotExist: new_obj = True cart_obj = Cart.objects.create(user=request.user) cart_obj.id = request.user.id return cart_obj class Cart(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) product = models.ManyToManyField(menulist, blank=True) total = models.DecimalField(default=0.0, max_digits=10, decimal_places=1) updated = models.DateTimeField(auto_now=True) timestamp = models.DateTimeField(auto_now_add=True) objects = CartManager() def __str__(self): return str(self.id) Here's my views: def cart_home(request): template = "cartapp/home.html" cart_id = request.user.id cart_obj = Cart.objects.new_or_get(request) context = { "x": request.user, } return render(request, template, context) -

Django : SQLite Database is Locked when I build like feature on my home page
I am implementing Like functionality in Web application. Idea is Simple to List number of Post(Blogs) on Home page and Add a Like Button to each post(Blog). It works fine when I build it with normal <form action='{% url target %}' method='POST'> But when I implemented this with AJAX call It only allows me to like or dislike a particular post(blog) a single time.i.e One I liked a Post for first time it works, also when I dislike the same Post It works fine, But when I again Like that Post it throws an django.db.utils.OperationalError: database is locked like_section.html <form id="like-form{{ post.id }}"> {% csrf_token %} <button type="submit" id="{{ post.id }}btn" name="like" value="{{ post.id }}" class="btn upvote">Like</button> <script type="text/javascript"> {% for like in post.likes.all %} {% if like != user %} dislikingPost("{{ post.id }}btn"); {% else %} likingPost("{{ post.id }}btn"); {% endif %} {% endfor %} $(document).ready(function(event){ $(document).on('click', '#{{ post.id }}btn', function(event){ event.preventDefault(); pk = $(this).attr('value'); $.ajax({ type: 'POST', url: '{% url "like_post" %}', data: { 'id': pk, 'csrfmiddlewaretoken': '{{ csrf_token }}' }, success:function(response){ $('#like-form{{ post.id }}').html(response['form']) // $('#{{ post.id }}btn').style.color = 'green'; }, error: function(er, e){ console.log(er.responseText); } }); }); }); </script> </form> views.py: def like_post(request): all_posts = Posts.objects.all() … -

Django Remove Login Alert Message AllAuth
I am using AllAuth with Django to make a logjn form. The issue is that I am trying to remove the error message in my login form that spawns from the form|crispy field, so that it only appears using the code at the bottom outside the form. Is this possible? Login.HTML <form class="login" method="POST" action="{% url 'account_login' %}" style="list-style-type: none;"> {% csrf_token %} {{ form|crispy }} {% if redirect_field_value %} <input type="hidden" name="{{ redirect_field_name }}" value="{{ redirect_field_value }}" /> {% endif %} <button class="primaryAction btn btn-primary shadow mt-2" style="width: 100%;" type="submit">{% trans "Sign In" %}</button> </form> // Added Error Message to Custom location {% if form.errors %} {% for field in form %} {% for error in field.errors %} <div class="container-fluid messages moveInTop"> <div class="alert alert-error alert-danger card"> {{ error|escape }} </div> </div> {% endfor %} {% endfor %} {% for error in form.non_field_errors %} <div class="container-fluid messages moveInTop" style="width: 28rem; z-index: 100; position: fixed; bottom: 10%; opacity: .95; left: 60.2%;"> <div class="alert alert-error alert-danger messages card"> {{ error|escape }} </div> </div> {% endfor %} {% endif %} -
Django AJAX returns undefined instead of the variables
So I have a simple Django script which I've found online for an AJAX function that runs a Python script and gets the output via stdout. views.py from django.shortcuts import render def index(request): return render(request,'homepage/page.html') homepage/page.html <html> <head> <meta http-equiv="content-type" content="text/html; charset=utf-8"> <title>test</title> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script> <script type="text/javascript"> $(function() { $('#clickme').click(function(){ alert('Im going to start processing'); $.ajax({ url: "static/homepage/js/external_func.py", type: "POST", datatype:"json", data: {'key':'value','key2':'value2'}, success: function(response){ console.log(response.keys); console.log(response.message); } }); }); }); </script> </head> <body> <button id="clickme"> click me </button> </body> </html> So you can see my url is linked to external_func.py which runs after the button is clicked. The script then returns a json. external_func.py import sys import json import cgi fs = cgi.FieldStorage() sys.stdout.write("Content-Type: application/json") sys.stdout.write("\n") sys.stdout.write("\n") result = {} result['success'] = True result['message'] = "The command Completed Successfully" result['keys'] = ",".join(fs.keys()) d = {} for k in fs.keys(): d[k] = fs.getvalue(k) result['data'] = d sys.stdout.write(json.dumps(result, indent=1)) sys.stdout.write("\n") sys.stdout.close() However, when I run the server and clicked on the button, the console shows undefined for both values, meaning response.keys and response.message is undefined. Now, when I instead switch the code to console.log(response) in homepage/page.html. The console prints out the entire external_func.py code in text. I couldn't find a solution … -
Django-Auth-LDAP with MemberUid
I am trying to configure django-auth-ldap to work with a very old LDAP schema that I have inherited. I am running into 2 issues with querying for LDAP groups. First, my LDAP schema uses the memberUid attribute rather than member attribute. Second, my LDAP schema has an uppercase OU that seems to be tripping-up django-auth-ldap. My django-auth-ldap setup is fairly straightforward, mostly taken directly from the official documentation. Here are a few significant lines. Note the uppercase 'G' in my OU. AUTH_LDAP_GROUP_SEARCH = LDAPSearch('ou=Group,dc=school,dc=edu', ldap.SCOPE_SUBTREE,'(objectClass=groupOfNames)',) AUTH_LDAP_GROUP_TYPE = GroupOfNamesType(name_attr='cn') AUTH_LDAP_USER_FLAGS_BY_GROUP = { "is_staff":"cn=org-staff,ou=Group,dc=school,dc=edu" } Here is a snipper of my ldap dump. cn: cn=org-staff,ou=Group,dc=school,dc=edu objectClass: posixGroup objectClass: top cn: org-staff gidNumber: 999 memberUid: someuser And here is a particularly telling line from my syslog. Dec 27 22:56:47 server slapd[45950]: conn=1467 op=4 CMP dn="cn=org-staff,ou=group,dc=school,dc=edu" attr="member" Dec 27 22:56:47 server slapd[45950]: conn=1467 op=4 RESULT tag=111 err=16 text= LDAP error 16 is LDAP_NO_SUCH_ATTRIBUTE, which makes sense in this case given that the query is looking for the member attribute but my group does not have any such attribute. The second issue here is that for some reason the 'G' in my OU is not capitalized in the query. Is there any way to make … -

Overriding settings in Django when used by the models
We are using Django for Speedy Net and Speedy Match (currently Django 1.11.17, we can't upgrade to a newer version of Django because of one of our requirements, django-modeltranslation). Some of our settings are used by the models. For example: class USER_SETTINGS(object): MIN_USERNAME_LENGTH = 6 MAX_USERNAME_LENGTH = 40 MIN_SLUG_LENGTH = 6 MAX_SLUG_LENGTH = 200 # Users can register from age 0 to 180, but can't be kept on the site after age 250. MIN_AGE_ALLOWED_IN_MODEL = 0 # In years. MAX_AGE_ALLOWED_IN_MODEL = 250 # In years. MIN_AGE_ALLOWED_IN_FORMS = 0 # In years. MAX_AGE_ALLOWED_IN_FORMS = 180 # In years. MIN_PASSWORD_LENGTH = 8 MAX_PASSWORD_LENGTH = 120 MAX_NUMBER_OF_FRIENDS_ALLOWED = 800 PASSWORD_VALIDATORS = [ { 'NAME': 'speedy.core.accounts.validators.PasswordMinLengthValidator', }, { 'NAME': 'speedy.core.accounts.validators.PasswordMaxLengthValidator', }, ] (which is defined in https://github.com/speedy-net/speedy-net/blob/uri_merge_with_master_2018-12-26_a/speedy/net/settings/global_settings.py). And then in the models I use: from django.conf import settings as django_settings class User(ValidateUserPasswordMixin, PermissionsMixin, Entity, AbstractBaseUser): settings = django_settings.USER_SETTINGS (and then use attributes of settings, such as settings.MIN_SLUG_LENGTH, in the class). The problem is, when I try to override such settings in tests (you can see my question & answer on Can I define classes in Django settings, and how can I override such settings in tests?), User.settings remains the same and is not overridden … -
How to remove "something ptr": when I render form with formset_factory?

problem with customize code samples in api documentation
I am trying to add swift code samples to the auto-generated api documentation in my django-rest-framework project.

How to access objects of grandparent model associated with target model through ContentType GenericForeignKey?
I'm trying to filter objects of model based on associated grandparent model. They are associated with each other through an intermediary parent model. Parent model is associated with grandparent through ContentType GenericForeignKey. How can I access all objects of target model sharing same Grandparent. I tried to use GenericRelations on Grandparent but it did not work as it returns all the Parent Objects associated with that GrandParent Model. For that, I've to loop through querysets.

Django - Form Does Not Save User Values

When a user hits “submit”, the page refreshes and the values stay in the input fields. I’ve tried many methods to solve this but no luck.

What is the purpose of setting a variable in self.send for Django Channels?
In Django Channels tutorial, you set a variable called 'text_message'.

What is the easiest way to tag user-submitted questions with category tags on a Django-base site?
I am building a site in Django where users submit questions about a wide range of topics. When a question is submitted, I would like it to be tagged with the various categories to which it belongs so it can be grouped with related questions. For example, if someone asks "does breastfeeding increase the risk of cancer?", I want that question tagged with categories like "child care, breastfeeding, cancer, etc". I understand that categorizing content is a common issue and I am curious what the best options are. -

Auto fill form field in html with data value and make it read only
I'm in process of creating a page where you can add a customer with some information regarding to them. I want to assign an unique id for each customer. I of course type in the basic information myself, but I also need a field in the form that has been populated with a generated random id, that has been checked in the database if it already exists.

Make django display non-jinja element while waiting for it to be completed
So here's what I'm trying to do. Let's say I have a really long function that takes some time to process. Eventually, the output needs to be displayed on a webpage. I'm using Python 3.6 and Django 2 framework. views.py from django.shortcuts import render import time def f(): time.sleep(5) return [5,6,7] def index(request): return render(request,'homepage/page.html', {'funcF':f}) So as you can see, I have a function that waits for 5 seconds to pass before returning an array of numbers. homepage/page.html <p> Hello there! </p> {% for r in funcF %} <p> {{r}} </p> {% endfor %} My goal is that I want Hello there! to be displayed and wait for 5 seconds to pass, then display the numbers in the array. In it's current state, the webpage instead takes 5 seconds to reload, and it displays both Hello there! and the numbers on the array all at once. Any bright ideas?
