How to fix urlpatternes does not match
I am using Django and javascript to create an URL that is entered by a form input but after submitting it I am getting an error that page does not exist even I have the pattern urlpatterns=[ path('chat',views.index,name='index'), path('chat/<str:room_name>',views.room,name='room'), ] and the javascript code is document.querySelector('#room-name-submit').onclick = function(e) { var roomName = document.querySelector('#room-name-input').value; window.location.pathname = '/chat/' + roomName + '/'; }; for example, if we enter lobby my url will be chat/looby and it should match with the 'room' , but I am getting error Using the URLconf defined in mychat.urls, Django tried these URL patterns, in this order: chat [name='index'] chat/ [name='room'] admin/ The current path, chat/lobby/, didn't match any of these. -
Django ORM: construct query that would look for match on field in object at the last position of many to many field
I stumbled upon something I can't figure out by myself - while filtering (in Django ORM) query I would like to query for objects meeting condition, that some field of last object in the list of many to many objects is equal to some input. It may sound not so obvious, so below I provide an example: Animal model class Animal(models.Model): name = models.TextField(null=True, blank=False) awards = models.ManyToManyField(Award, related_name='awards') Award model class Award(models.Model): name = models.TextField(null=False, blank=False) place = models.TextField(null=True, blank=True) date = models.DateTimeField(null=True) Having these classes, I would like to construct query like this: Animal.objects.filter(awards__name__last='National Award') Because Animal.objects.filter(awards__name='National Award') normally returns (when using .values()) list looking like this: [{'name': u'National Award', 'place': u'capital', 'date': datetime.datetime(2018, 7, 13, 5, 2, 45, 23000), u'id': 1}, {'name': u'International Award', 'place': u'capital', 'date': datetime.datetime(2018, 10, 1, 1, 1, 55, 79000), u'id': 2}] and for such object, query would ommit it, because 'National Award' is not on the last position on the list, but if this object would have switched these entries, it would be returned by this query, since the last object name is equal to 'National Award'. I do not want to use date field for this query. -
CORS did not succed when deployed on heroku https, works locally
I have a fullstack Django and React app, which works perfectly on my local machine with no issues, but when I deploy it on Heroku I got this well-known error: Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at (...), but the problem does not occur when I use HTTP instead of HTTPS.

Django constance variable check in settings.py
I am trying to enable custom logging toggle check inside settings.py as shown below(the code is at the bottom of the file): from constance import config if config.CUSTOM_LOGGING: LOGGING = { 'version': 1, 'disable_existing_loggers': True, 'formatters': { 'standard': { 'format': '%(asctime)s [%(levelname)s] : %(message)s' }, }, 'handlers': { 'default': { 'level': 'DEBUG', 'class': 'logging.handlers.RotatingFileHandler', 'filename': 'pd_temp/celery_logs/allume_feed_jobs.log', 'maxBytes': 1024 * 100, # 100 kB 'backupCount': 5, 'formatter': 'standard', }, }, 'loggers': { '': { 'handlers': ['default'], 'level': 'DEBUG', 'propagate': True }, } } But I am getting this error: django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet.

NoReverseMatch Django Chat message another user
I'm probably missing something here, but I have a connect page in which the logged in user can chat to another user by clicking on a Chat? link located on each users profile. The chat functionality is built using Django Channels and is accessed via the url pattern site/messages/username where username is the other_user that the current_user is chatting with. I currently have the chat? link as <a class='btn btn-light' href="{% url 'thread' username %}" id="chat">Chat?</a> However that throws the error NoReverseMatch Reverse for 'thread' not found.

Inside React JS, I am already calling the API with http://127.0.0.1:8000/author_list/. Will Nginx works fine without /api? -
How do I access variables from form_valid in get_success_url in a FormView?

Generating files after adding model instance through django admin interface
I'm writing a model for a website. When a user adds an instance of the model through the Django admin, I want to catch the event and automatically generate files, including adding a reference path field for those created files. Django admin has a clean method that can be overridden. I can create and update files and fields through this. def clean(self): info = self.cleaned_data.get('info') ... #Generate IO paths from info self.cleaned_data['template_path'] = template_path self.instance.template_path = template_path return self.cleaned_data I need to create a distinction between add and change events, so I'm not writing files and changing the pathing post object creation. Is there a way to do this within clean, or should I be looking elsewhere to create fields & update fields?
