For loop of javascript working for constant length like 4,5 or 6 but not working for carts.length
I am following a tutorial, but this piece of javascript code is not working at all. I tried to debug it using alert but I found that the first alert i.e 'going'alert is working but second alert 'work' alert is not working. When Ia am replacing 'carts.length with an integer like 3,4 or 5 it is working correctly This is the javascript code: let carts = document.querySelectorAll('.update-cart'); alert("going") for (let i=0;i < carts.length ;i++){ alert("work") console.log("looping"); } Tjis is the html code related to this: {% for i in product %} <div class="col-xs-3 col-sm-3 col-md-3"> <div class="card" style="width: 18rem;"> <img src='/media/{{i.image}}' class="card-img-top" alt="..."> <div class="card-body"> <h5 class="card-title">{{i.product_name}}</h5> <p class="card-text">{{i.desc}}</p> <button data-product="pr{{i.id}}" data-actions="add" class="btn btn-primary add-btn update-cart">Add to Cart</button> </div> </div> </div> {% if forloop.counter|divisibleby:4 and forloop.counter > 0 and not forloop.last %} </div> Please tell me what I am doing wrong. I want to use localStorage in javascript. I am using Django as backend. Thanks in advance. -

Django database problems after pushing to github for heroku to build
I built my Django website locally, and tested it all locally and everything was working fine so I decided to get it on Heroku. I set it up so that I push it to a github project, then Heroku builds it from there and deploys it to the site. The only problem I'm having is with the database. Here's the setup in my settings.py: DATABASES = {'default': dj_database_url.config(conn_max_age=600, ssl_require=True)} if DATABASES['default'] == {}: DATABASES['default'] = { 'ENGINE': 'django.db.backends.sqlite3', 'NAME': os.path.join(BASE_DIR, 'db.sqlite3'), } At the end of the file I have "django_heroku.settings(locals())". So before I push it to github I clear the migrations folder only because I've been having problems, then I add, commit, push, and do the migrate via "heroku run --app app_name python manage.py migrate" which then tells me to do makemigrations before migrate, but I've already done it. So I've no idea what I'm doing wrong. Thank you in advance for any help. -
Django Extending class based view dynamically
Is there a good way to dynamically choose which view I want to extend in my class based view in Django? Right now I have 2 views(update and view) as follows that I would like to collapse into 1: from django.views.generic import UpdateView, DetailView from guardian.mixins import PermissionRequiredMixin class MyUpdateView(PermissionRequiredMixin, UpdateView): model = MyModel permission_required = 'MyApp.change_mymodel' template_name = "MyApp/update.html" fields = ["name", "Type", "description"] class MyDetailView(PermissionRequiredMixin, DetailView): model = MyModel permission_required = 'MyApp.view_mymodel' template_name = "MyApp/view.html" What I would like to do is have 1 view, and 1 url, and when the view is accessed if the user has the change permission, it should use UpdateView, if they have the view permission use DetailView, and if they have neither display some kind of error. Is there a way to make that work? -
AttributeError: 'NoneType' object has no attribute 'split' - Error when saving users in ajax call
Views.py The following attempt to save both my student (which extends User model) and my user, gives a long series of errors. What is the best way around this?

MySQL user privileges for testing Django app
I am using MySQL with Django. Are my only choices for allowing testing the following? I don't want to keepdb. GRANT ALL ON *.* to '<user>'@'localhost' so that the user can create test databases, etc. Test on sqlite which is almost the same thing but isn't MySQL and important if I am testing for everything. Option 1 seems a little unsafe and Option 2 still leaves the door open for untested areas. Is there another option in terms of the privileges I can grant or ways to think about it? -
Unable to authenticate user with Django Rest Framework from certain subdomains
My current setup consists of the following: 1) React JS application (react.example.com:3000) 2) Flask server to serve backend API calls (backend.example.com:5000) 3) Authentication server using Django Rest Framework (auth.example.com) I have configured the authentication server to use session authentication with these settings: SESSION_COOKIE_DOMAIN = '.example.com' CORS_ALLOW_CREDENTIALS = True SECURE_SSL_REDIRECT = True SESSION_COOKIE_SAMESITE = None SESSION_COOKIE_SECURE = False CSRF_USE_SESSIONS = True I have also setup an endpoint at auth.example.com/check_auth in Django to check if a user is authenticated def authorization(request): if request.user.is_authenticated: return HttpResponse('User is Authenticated') else: return HttpResponse('Not Authenticated') When I send a GET request to the endpoint from my ReactJS application after logging in, I receive the correct response 'User is Authenticated'. This works fine. However, I want send a similar request within certain endpoints in my Flask server but its not working. For example: @app.route('/check', methods=['GET']) def check_auth(): res = requests.get('https://auth.example.com/check_auth') return res.text After I login and send a GET request to backend.example.com:5000/check through the React application, I expected the return to be 'User is authenticated' but instead I get 'Not Authenticated'.

How to export text value instead of foreign key id from mysql table to excel in django

I am running a Django test server on a remote Ubuntu nginx server. How can I access the Django interface from my local machine?
Right now, if I go to [remote server's IP] on Chrome, for example, it'll take me to the "Welcome to nginx" page. I have Django installed on this server, and when I run "python manage.py runserver" it starts the Django test server on which my app is stored. If this were on my local machine, I could just go to [localhost] on Chrome and it would show my Django app, but I'm not quite sure how to get to it on the remote server. Is this possible? Is there a better, cleaner way to do this - perhaps just configuring the Django project to run on the nginx server that is already created? -
Sending email via subdomain address with GSuite and Django
I've got G Suite/Gmail fully integrated with my django project and it works great. I'd like to send mail from a subdomain-based address, however (eg. support@mailer.mywebsite.com). I've gone into GSuite and added a new domain (support@mailer.mywebsite.com) and vertified control of the domain. Within my django project, I've updated the sender email to reflect the new address. from_email = 'support@mailer.mywebsite.com' send_mail( subject, txt_message, from_email, to_email, html_message=html_message, fail_silently=False, auth_user=authorizeduser.user_name, auth_password=authorizeduser.gsuite_app_password ) Unfortunately, the mail being sent out still has support@mywebsite.com as the sender.

Change the ordering of a TextField constrained by choices in the Django admin site
I would like to change the ordering of my size column in the Django admin site. The size column is based on a model.TextField with a choices constraint. Something like this: from django.db import models size_choices = [ ('P', 'Preemie'), ('N', 'Newborn'), ('0-3M', '0-3M), ('...', ), ] class Clothes(models.Model): size = models.TextField(max_length=20,choices=size_choices) with the following admin model: from django_admin_multiple_choice_list_filter.list_filters import MultipleChoiceListFilter class SizeListFilter(MultipleChoiceListFilter): title = 'Size' parameter_name = 'size__in' def lookups(self, request, model_admin): return size_choices @admin.register(Clothes) class ClothesObject(admin.ModelAdmin): list_display = ('get_name', 'type', 'size', '_seasons', '_colors', '_genders') list_filter = (SizeListFilter,TypeListFilter, SeasonListFilter, GenderListFilter) <snip> Now, I've made the probably unfortunate decision of having the id (the first element of each tuple) being the same as the label. It seems that, by default, clicking on the Size column heading on the admin site orders by ID. Changing the IDs to some numerical value causes a migration, but does not map the old IDs to the new IDs (as expected). How can I provide a custom ordering for the size TextField in the Django admin site? Ideally I'd want the items to appear in the same order that they do in the size_choices list. -

How do I query a full (or partial) name built from two separate model CharFields (first_name and last_name) in Django?

I'm using Django 3.0.8 and I created a UserProfile-model in order to add more fields to the default django.contrib.auth.models.User-model with a OneToOne relation. I would like to use the default class based views such as django.contrib.auth.views.LoginView, LogoutView, PasswordChangeView, PasswordResetView. The problem is that the labels, the helptext and the error messages of the forms are standard and in the language indicated by the settings.LANGUAGE_CODE value. I tried to make custom form classes from the default Django form classes such as AuthenticationForm, PasswordChangeForm, PasswordResetForm or UserCreationForm. In the UserCreationForm, I also tried to add the form fields of the UserProfile-model so that the user can fill his/her profile data during his/her registration. The problem is that I must override every label, every helptext and every error message of each form in order to use ugettext on it. I would like to know if I'm wasting my time because the class based views and forms already supports ugettext. And if not, if there is a way to easily override the default labels, helptexts and error messages of each form. Here is what I currently made: This is the models.py-file: from django.contrib.auth.models import User from django.db import models from django.db.models.signals import post_save from … -
Is a GeoDjango MultiPolygonField supposed to accept a Polygon geometry?
When I try to set a Polygon on a MultiPolygonField the following exception is raised: Traceback (most recent call last): File "<console>", line 1, in <module> File "/Users/mattrowbum/.virtualenvs/my_env/lib/python3.7/site-packages/django/contrib/gis/db/models/proxy.py", line 75, in __set__ instance.__class__.__name__, gtype, type(value))) TypeError: Cannot set Location SpatialProxy (MULTIPOLYGON) with value of type: <class 'django.contrib.gis.geos.polygon.Polygon'> That would be understandable, except that a note in the GeoDjango tutorial states: ...a GeoDjango MultiPolygonField will accept a Polygon geometry. I've had a look at the source of proxy.py, and it is checking whether the value (a Polygon) is an instance of the relevant geometry class (a MultiPolygon). I've tried doing this check manually which confirms that a Polygon does not inherit from MultiPolygon: >>> from django.contrib.gis.geos import MultiPolygon, Polygon >>> ext_coords = ((0, 0), (0, 1), (1, 1), (1, 0), (0, 0)) >>> int_coords = ((0.4, 0.4), (0.4, 0.6), (0.6, 0.6), (0.6, 0.4), (0.4, 0.4)) >>> poly = Polygon(ext_coords, int_coords) >>> isinstance(poly, Polygon) True >>> isinstance(poly, MultiPolygon) False Is the note in the tutorial misleading or am I doing something wrong? -
Django only returning first value of for loop
I am running a for loop with a button that submits a url. The buttons are in a for loop and when I press one, it only returns the first url of the for loop. My input looks like this: <input type="submit" id="choice{{ forloop.counter }}" value="Save" class="btn btn-primary" /> <input type="hidden" id="choice{{ forloop.counter }}" name="url" value="{{ article.articledata.url }}"> and my view looks like this: url = (request.POST["url"]) No matter which submit I press, I get the same request.POST value. Please help.
