Redirecting user to dynamic url after google login using django allauth
NOTE: I asked this question 5 days ago without response so trying again. Remove if this violates the rules of duplicate questions. I am using google sign in to authenticate users using django allauth. There is no need to log the user in prior to them trying to interact with the website, which happens at https://www.example.com/example/5 where 5 is just an id to a model instance in my database. After user login, I would like to redirect the user to the same page they are on. Would it be possible to do this either through passing the model id (5 in this example) through the google credentials and receive the number back at the /accounts/google/login/callback/ callback, or something similar? Or perhaps there is way using django allauth. This question is close to what I need, but I don't know how to get access to the model ID using this approach. Django-Allauth, Multiple login redirect url # In myapp/adapter.py from allauth.account.adapter import DefaultAccountAdapter class AccountAdapter(DefaultAccountAdapter): def get_login_redirect_url(self, request): url = super(AccountAdapter, self).get_login_redirect_url(request) user = request.user ''' # pseudocode, change it to actual logic # check user role and return a different URL role = get_user_role(user) if role == 'student': url = … -
Why is CSS not updating with live reload in django
I just figured out how to use live reload with django - (How to get liveserver to render django templates?). I used the first answer (but instead of ./manage.py livereload, I did python manage.py livereload. My problem is that now the CSS is not uploading. I know it is because of the live reload because when I use the regular python manage.py runserver, the CSS loads. Any help on this will be appreciated. (When in my command prompt (I use Windows 10), and while in the directory which contains the manage.py file, I type ./manage.py livereload.) -

TemplateDoesNotExist at / on Heroku while working on local server
New to Django and Heroku; I get "TemplateDoesNotExist at /" when loading the page. Have read somewhere that it might have something to do with Caps. My template is called templates. In settings.py : from pathlib import Path BASE_DIR = Path(__file__).resolve().parent.parent print(BASE_DIR) print(BASE_DIR / 'templates') And TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [BASE_DIR / 'templates'], 'APP_DIRS': True, 'OPTIONS': { 'context_processors': [ 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.contrib.messages.context_processors.messages', ], }, }, ] HOWEVER in the error, I get : "django.template.loaders.filesystem.Loader: /app/Templates/homepage.html (Source does not exist)" It seems like Heroku doesn't upload the changes I've made to settings.py even though I get "Everything up-to-date" Everybody seems to be using os.path.join but my Pathlib is working correctly (I assume). Thanks in advance for any help :) -
Map selected radio button to existing post category: Cannot assign "'Artikel'": "Post.category" must be a "Category" instance
I want to map radio buttons to given categories. One way is to do this with the help of a choice field. I don't know if this is a good approach. I have seen many other articles and SO-posts but they did not point me to a direction from where I could see my mistake - so after many hours of research I wanted to ask you here. Thanks! models.py class Category(models.Model): title = models.CharField(max_length=255, verbose_name="Kategorie") ... class Post(models.Model): title = models.CharField(max_length=150) .... category = models.ForeignKey(Category, verbose_name="Kategorie", forms.py CAT_CHOICES= [ ('Artikel', 'Artikel'), ('Videos', 'Videos'), ('Anderes', 'Anderes'), ] class PostForm(forms.ModelForm): category = forms.ChoiceField(widget=forms.RadioSelect, choices=CAT_CHOICES) class Meta: model = Post # is this throwing an error because I only handle the 'Post' model? fields = [ 'title', ... 'category', ] views.py def function_name(request): ... if request.method == 'POST': form = PostForm(request.POST) if form.is_valid(): # error happens here template.html: <label>Artikel</label> <input id="category0" type="radio" name="category" value="Artikel"> <label>Videos</label> <input id="category1" type="radio" name="category" value="Videos"> <label>Anderes</label> <input id="category2" type="radio" name="category" value="Anderes"> output: ValueError at / Cannot assign "'Artikel'": "Post.category" must be a "Category" instance.

404 error when access Wagtail cms page after Integrating Wagtail with existing Django project
I am new to Wagtail and intended to learn by practice. Django=3.0.5 | Wagtail=2.13.1 | Python=3.7.10 I have existing Django project with below file structure: |- manage.py |- static/ |- templates/ |- IoTSite/ ___|- urls.py ___|- settings.py ___|- ... I was strictly following Wagtail official guide: Integrating Wagtail into a Django project for this integration. However, after I finish the root urls.py config, // IoTSite/urls.py urlpatterns = [ path('',TemplateView.as_view(template_name='homepage.html'),name='home'), path('admin/', admin.site.urls), path('article/',ArticleListView.as_view(template_name='TL_ArticleList.html'),name='article-list'), path('article/<int:pk>/',ArticleDetailView.as_view(template_name='TL_ArticleDetail.html'),name='article-detail'), path('archive/<int:year>/<int:month>/', ArticleMonthArchieveView.as_view(month_format='%m',template_name='TL_ArticleList.html'),name='archive_mmonth'), path('cms/', include(wagtailadmin_urls)), path('documents/', include(wagtaildocs_urls)), path('pages/', include(wagtail_urls)), ] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) when I try to access Wagtail admin site; http://127.0.0.1/cms/ I encountered 404 not found error with below debug details. Using the URLconf defined in IoTSite.urls, Django tried these URL patterns, in this order: 1. [name='home'] 2. admin/ 3. article/ [name='article-list'] 4. article/<int:pk>/ [name='article-detail'] 5. archive/<int:year>/<int:month>/ [name='archive_mmonth'] The current path, cms/, didn't match any of these. Q1: Why 127.0.0.1/cms was not matched when it was clearly configured in urls.py? are there any required configs not mentioned in the official guide ? Q2: Behind the scene, how Django and Wagtail interacts with each other? I did not see a Watgail app folder within the Django project directory, it seems that Django interacts with Wagtail purely via import … -

How to correctly get variables from Django to javascript and do a GET ajax call on a Django URL?
I apologize if I butchered the terms there. I'm learning webdev and I still don't understand how these technologies work together, so I'm writing everything that might contribute to the problem. Here's where I'm at right now: The urlpatterns in sites/urls.py: urlpatterns += [ path('api/test/<str:crop>/<str:category>/<str:date_from>/<str:date_to>/', data.get_test_page_data), path('test/<str:item>/<str:category>/<str:date_from>/<str:date_to>/', data.render_initial_test_page) ] The functions in data.py: def get_test_page_data(item, category, date_from, date_to): date_from = datetime.datetime.strptime(date_from, "%Y-%m-%d") date_to = datetime.datetime.strptime(date_to, "%Y-%m-%d") data = Items.objects.all().filter(item=item, category=category, date__range=[date_from, date_to]) context = { "data" : data, } return JsonResponse(context) def render_initial_test_page(response, item, category, date_from, date_to): ... context = { "item" : item, "category" : category, "date_from" : date_from, "date_to" : date_to } return render(response, 'sites/test.html', context) The test.js: var sites, map; var test_data; var item = '{{ item }}'; var category = '{{ category }}'; var date_from = '{{ date_from }}'; var date_to = '{{ date_to }}'; getTestData(); function getTestData() { $.ajax({ method: 'GET', url: '/api/test/' + item + '/' + category + '/' + date_from + '/' + date_to + '/', success: function(data) { test_data = data; renderTestData(); } }); } The problem: It doesn't work.

How to print filtered results from django model
I am trying to print the filtered results from a django model.

Django Celery background scraper
I need some help, My setup is Django, Postgres, Celery, Redis – all dockerized. Besides regular user-related features, the app should scrape info in the background mode. What I need is to launch the scraping function manually from management command like "python manage.py start_some_scrape --param1 --param2 ..etc", and know that this script works in the background mode informing me only by logs. At this moment script works without Celery and only while the terminal connection is alive what is not useful because the scraper should work a long time – like days. Is Celery the right option for this? How to pass a task from management command to Celery properly? How to prevent Celery to be blocked by the long-time task? Celery also has other tasks – related and not related to the scraping script. Is there are threads or some other way? Thx for help! -

Prevent Django from Removing Previous Entries in PostgreSQL
I have the following Django code that is being run on PostgreSQL and Huey (an automatic scheduler). The problem is that, whenever the periodic task is run, Django removes the previous rows in a table instead of adding on to existent ones. Scheduled code: @periodic_task(crontab(minute='*/1')) def scheduled(): team = nitrotype.Team('PR2W') team_id = team.data["info"]["teamID"] timestamp = datetime.datetime.now() for members in team.data["members"]: racer_id = members["userID"] races = members["played"] time = members["secs"] typed = members["typed"] errs = members["errs"] rcd = RaceData( racer_id=racer_id, team_id=team_id, timestamp=timestamp, races=races, time=time, typed=typed, errs=errs ) rcd.save() Basically, the above code is going to run every minute. Here's the database (PSQL) data that I started with: nttracker=# TABLE data_racedata; racer_id | team_id | timestamp | races | time | typed | errs ----------+---------+------------+--------+---------+----------+-------- 35051013 | 765879 | 1623410530 | 4823 | 123226 | 793462 | 42975 35272676 | 765879 | 1623410530 | 8354 | 211400 | 1844434 | 38899 36690038 | 765879 | 1623410530 | 113 | 2849 | 16066 | 995 38486084 | 765879 | 1623410530 | 34448 | 903144 | 8043345 | 586297 38625235 | 765879 | 1623410530 | 108 | 2779 | 20919 | 1281 39018052 | 765879 | 1623410530 | 1908 | 48898 | 395187 | … -

Django seems to not escape XSS attacks?
I will appreciate your help in this so much, I am developing a Django application and everything is fine and working. I was reading yesterday about security breaches and how django templates permit to block dangers like csrf, xss...etc. So I wanted to test my app if it does escape an xss attempt before I move on with my app and duplicate my models, forms, and views. What I did was that I have entered as input <script alert("xss"); in one of my forms (POST), pressed the submit button, and checked the entered instance in a list view. My problem is that it was there with the exact same input without any sort of encrypting from Django. Yes, the javascript didn't get executed and no alert message showed, but isn't Django supposed to escape/encript html tags? I have also inspected the code source behind and, similarly, the result is exactly as I have entered it. The same thing in the database. The input is stored as it is without escaping the html tags. Am I missing something or it is how it's supposed to be? My product view in views.py def add_product(request): pharmacy = Pharmacy.objects.get(id=1) form = ProductForm(initial={'pharmacy':pharmacy}) if request.method=='POST': … -

How to add a prefix before the domain name in a url in django?
I want to create custom url like this http://admin:testserver.com/login/ I've been trying different ways to to achieve this but all of my efforts were in vain. After reading Django document i'm able to create a custom url where i can add a certain prefix after the domain name which look like this "http://127.0.0.1:8000/mod:add_product/" with this line of code url(r'^mod:', include('moderator.urls')), My friend was suggesting to use django_subdomains to get a somewhat similar url which would look like this "http://admin.xyz.com/loign" i was considering that as an option but django_subdomains has been abandoned since July 2019 is there any other options to create such urls?
