Django: Can't access data on template through foreign_key
I want to access transaction_ambassador in my template. Therefore my approach is going through the order model as I already use it and it's foreign_key. What I did was {{ order.ambassador_transaction }}. But all I get is ambassadors.AmbassadorTransaction.None. I checked it several times, but it is connected through the foreign_key. Anyone knows what I am doing wrong here? views.py class OrderListView(ListView): allow_empty = False template_name = 'orders/order_list.html' def get_queryset(self): return Attendee.objects.filter( order__order_reference=self.kwargs['order_reference'], order__access_key=self.kwargs['access_key'], ) def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['order'] = Order.objects.get( order_reference=self.kwargs['order_reference'], ) return context models.py class AmbassadorTransaction(models.Model): order = models.ForeignKey( Order, on_delete=models.PROTECT, related_name='ambassador_transaction' ) ambassador = models.ForeignKey( AmbassadorProfile, on_delete=models.PROTECT, related_name='ambassador_profile' ) class Order(models.Model): event = models.ForeignKey( Event, on_delete=models.PROTECT, related_name='orders' ) order_reference = models.CharField( max_length=10, unique=True, ) total_gross = models.DecimalField( max_digits=25, decimal_places=2 ) created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) -

Not able to install mysqlclient
I am new to django but I know MySQL. However I wanted to connect django with mysql but is stuck at this point where I have to install mysqlclient but getting the error. I have already installed mysql server, created a virtualenv but still not able to install mysqlclient.

Use of single underscore before parentheses in Django
I've seen a lot of examples if Django of people doing things like class Person(models.Model): SEX_CHOICES = ( ('male', _('male')), ('female', _('female')), ('non-binary', ('non-binary')), ) first_name = models.CharField(_('first_name'), max_length=25) last_name = models.CharField(_('last_name', max_length=50) sex = models.CharField(_('sex'), choices=SEX_CHOICES, max_length=100) Meta: verbose_name = _('first_name') What does the the single leading underscore do? I assume that it's doing something about translating the names into database field names, but I'm having trouble finding anything in the official documentation that mentions it. Is this still a thing in Django 2.0? -
Get Django admin password
I'm using Django (version 2.0) as a newbie and have forgotten the admin superuser password. I know that I can create another superuser and change the password of the previous superuser as well. But is there any procedure to know the RAW password of the previous superuser which I've forgotten? -
Profiling python Gunicorn Django application only shows low level calls, not my code
I am profiling my django application which runs on a gunicorn WSGI webserver. I use werkzeug which takes care of profiling with cProfile. Basically the only thing I had to do to make it work was to add the Middleware from werkzeug.contrib.profiler import ProfilerMiddleware from django.core.wsgi import get_wsgi_application os.environ.setdefault("DJANGO_SETTINGS_MODULE", "main_app.settings") application = ProfilerMiddleware(get_wsgi_application(), restrictions=(30,)) application = get_wsgi_application() Everything works fine but I only see stats from what seems to me system calls, but not my packages, I guess I have to add them somehow to the profiler so he knows about it, can someone tell me how? 263632 function calls (233580 primitive calls) in 8.682 seconds 3:19:46 PM web.1 | Ordered by: internal time, call count 3:19:46 PM web.1 | List reduced from 1091 to 30 due to restriction <30> 3:19:46 PM web.1 | ncalls tottime percall cumtime percall filename:lineno(function) 3:19:46 PM web.1 | 54 4.160 0.077 4.160 0.077 {method 'read' of '_ssl._SSLSocket' objects} 3:19:46 PM web.1 | 6 2.599 0.433 2.599 0.433 {method 'do_handshake' of '_ssl._SSLSocket' objects} 3:19:46 PM web.1 | 6 1.094 0.182 1.094 0.182 {method 'connect' of '_socket.socket' objects} 3:19:46 PM web.1 | 11 0.055 0.005 0.055 0.005 {method 'sendall' of '_socket.socket' objects} 3:19:46 PM web.1 | … -

Django won't let me run migrate because the check function detects references to a new field I am adding
I am adding a new field to a model, but I can't get the migration to work sqlite3.OperationalError: no such column: main_language.iso639_1 I could only generate the migration file with makemigration by commenting out all references to the new field in my code, but now I can't run migrate without keeping the field commented out. This is not acceptable as referencing my new field obviously needs to eventually appear in my code and anyone else pulling the latest version of the codebase will have the uncommented code when they attempt to run the migration. I haven't had this problem before despite adding new fields to models many times, not sure why it is happening this time: # iso639_1 is the new field class Language(TranslatableMixin, models.Model): ENGLISH = 1 # id for English should always be 1 ISO_HELP_TEXT = _("Please find the correct code at: https://www.loc.gov/standards/iso639-2/php/code_list.php") title = models.ForeignKey('main.Sentence', on_delete=models.PROTECT, related_name='LanguageTitle') iso639_2 = models.CharField(max_length=8, help_text=ISO_HELP_TEXT) iso639_1 = models.CharField(max_length=8, blank=True, default='', help_text=ISO_HELP_TEXT) author = models.ForeignKey(User, on_delete=models.SET_NULL, null=True) created = models.DateTimeField(auto_now_add=True) objects = LanguageManager() Error I receive when trying to run 'python manage.py migrate': Traceback (most recent call last): File "C:\Users\Win7\OneDrive\Programming\Git\lang\.venv\lib\site-packages\django\db\backends\utils.py", line 85, in _execute return self.cursor.execute(sql, params) File "C:\Users\Win7\OneDrive\Programming\Git\lang\.venv\lib\site-packages\django\db\backends\sqlite3\base.py", line 303, in … -
Django - Posting jQuery dictionary object via Ajax returns None
I have an Ajax function in my Django project resembling the following... $('#btn-submit').click(function(e){ e.preventDefault(); var btn = $(this); var dataUrl = btn.attr('data-href'); var title = $('#title').val(); var dict = {}; $('.choice-m2m-check').each(function(i){ k = $(this).val(); v = $(this).attr('data-value'); dict[k] = v; }); $.ajax({ url:dataUrl, method:'POST', data:{ 'title':title, 'dict':dict, }, success:function(data){ if (data.saved){ ... } }, error:function(error){ ... } }); }); So I have a {key: value, ...} dictionary which assigns a 'true' or 'false' boolean flag to each item. This is then posted to the URL represented by 'dataUrl' where Python does some checks on the data. So firstly, in the jQuery after the key value pairs have been assigned, I console log the value of dict using console.log(dict) which gives me something like the following {item-885564895: "true", item-0385245877: "false"} in the console. The problem is that in my Django view where I print the posted value of request.POST.get('dict') then it prints None. Note that when I print the 'title' field which is a regular string then printing it returns the value of the title. What am I doing wrong? -
Password field doesn't hide the password in the sign up form

JWT Token fails to validate if multiple clients send tokens to Django Server
I have built a token based authentication/permission system in Django (not using REST Framework). When a user logs in, a JWT token is generated using this code - token = jwt.encode({'user': email, 'exp': datetime.datetime.utcnow() + datetime.timedelta(hours=48)}, settings.secret_key) The token is sent as part of response to the AngularJS Frontend and stored there in a cookie and user is navigated to the landing page. When the user tries to visit any other page on the site, the token is sent as part of the request Authorization Header and received in the django backend to be validated by a wrapper - def token_required(f): @wraps(f) def decorated(request, *args, **kwargs): token = None print >> sys.stderr, settings.secret_key try: if request.META['HTTP_AUTHORIZATION']: token = request.META['HTTP_AUTHORIZATION'] print("HTTP AUTH TOKEN: " + request.META['HTTP_AUTHORIZATION']) else: return Response().sendinvalidresponse('User is not Authorised.

In my views (in app web for example) I am able to do reverse URL, for example in my login view I do return redirect('backoffice:dashboard') and it works just perfectly - its redirecting to /backoffice/. Problem is when I try to do reverse urls in my templates. In one of my templates, when I add code: <li class="featured"><a href="{% url 'backoffice:dashboard' %}">{% trans 'Open dashboard' %}</a></li> I get django error: NoReverseMatch at / 'backoffice' is not a registered namespace I suppose that problem is related to django-decorator-include, because if I change my include to standard django url include: path('backoffice/', include('backoffice.urls', namespace='backoffice')), it works just fine, and … -

Modifying multiple objects simultaneusly with Django

Django - What CBV should I use for my case?
First of all, I want to say that I'm really a novice with Django, and looking for some architectural advice for my project. I have a front-end template that looks like this: When a user clicked "save" button, data in the input fields needs to be saved into a database. The users will be constantly updating these input fields with new values, and there will be a case where none of these data is present in the database, because the user hasn't filled them out yet. The problem is, I am not sure what view method to use. views.py class BhaCreateView(CreateView): model = models.bha fields = '__all__' context_object_name = 'bha' template_name = 'base/bha.html' This just a really rough code that I made just ask a question here. I'm aware that there are many kind of class-based-views, such as DetailView, ListView, CreateView, UpdateView... and many more. Which one, or ones should I use for my purpose? I'm thinking that I need some combination of CreateView and UpdateView, since the users will be updating new information to BHA section, but there still are chances that information was not inserted in the first place at all. How should I do this? -
Django - what is the use of 'super' keyword in python?

Add new provider to Django-AllAuth (SteadyHQ.com)
I want to add a new provider (SteadyHQ.com) to the Django-allauth app. SteadyHQ is similar to patreon but from Germany. I have made a fork of the project and add SteadyHQ as a provider. Unfortunately I stuck with the implementation :( You can finde the documentation of the SteadyHQ API here. I have create a new provider and create the social account with my client ID and Security Code. Additional I have add the following code to my settings.py: SOCIALACCOUNT_PROVIDERS = { 'steadyhq': { 'SCOPE': ['read'] } } For testing I have to use ngrok because it is not possible to use "localhost:XXXX" as redirect url at SteadyHQ. Now the redirect URL looks like http://personallink.ngrok.io/accounts/steadyhq/login/callback/ If I try to login with SteadyHQ.com I come to the access grant page from SteadyHQ.com. I give my App full access and get following callback: http://personallink.ngrok.io/accounts/steadyhq/login/callback/?code=SomeSpezialCode&state=SomeSpecialState BUT my site show an "Social Network Login Failure. An error occurred while attempting to login via your social network account.". I have no Idea how to deal with it and get the other parts to work... I hope someone can help my. Thank you very much! Best regards Tobit
