Django Secret Key Must Not Be Empty Error
I am trying to run django on AWS EC2 framework tensorflow_p36 which has its own virtualenv as tensorflow_p36. It is providing python3.6 as the language version. I found there was a conflict with mod_wsgi which was running on python3.5 so I had to reinstall it. Now the problem with mod_wsgi has gone but another problem -- Django secret key error Traceback (most recent call last): File "./manage.py", line 14, in application = django.core.handlers.wsgi.WSGIHandler() File "/home/ubuntu/anaconda3/envs/tensorflow_p36/lib/python3.6/site-packages/django/core/handlers/wsgi.py", line 135, in init self.load_middleware() File "/home/ubuntu/anaconda3/envs/tensorflow_p36/lib/python3.6/site-packages/django/core/handlers/base.py", line 34, in load_middleware for middleware_path in reversed(settings.MIDDLEWARE): File "/home/ubuntu/anaconda3/envs/tensorflow_p36/lib/python3.6/site-packages/django/conf/init.py", line 79, in getattr self._setup(name) File "/home/ubuntu/anaconda3/envs/tensorflow_p36/lib/python3.6/site-packages/django/conf/init.py", line 66, in _setup self._wrapped = Settings(settings_module) File "/home/ubuntu/anaconda3/envs/tensorflow_p36/lib/python3.6/site-packages/django/conf/init.py", line 157, in init mod = importlib.import_module(self.SETTINGS_MODULE) File "/home/ubuntu/anaconda3/envs/tensorflow_p36/lib/python3.6/importlib/init.py", line 126, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "", line 994, in _gcd_import File "", line 971, in _find_and_load File "", line 955, in _find_and_load_unlocked File "", line 665, in _load_unlocked File "", line 678, in exec_module File "", line 219, in _call_with_frames_removed File "/var/www/picslo/picslo/settings.py", line 15, in django.setup() File "/home/ubuntu/anaconda3/envs/tensorflow_p36/lib/python3.6/site-packages/django/init.py", line 19, in setup configure_logging(settings.LOGGING_CONFIG, settings.LOGGING) File "/home/ubuntu/anaconda3/envs/tensorflow_p36/lib/python3.6/site-packages/django/conf/init.py", line 79, in getattr self._setup(name) File "/home/ubuntu/anaconda3/envs/tensorflow_p36/lib/python3.6/site-packages/django/conf/init.py", line 66, in _setup self._wrapped = Settings(settings_module) File "/home/ubuntu/anaconda3/envs/tensorflow_p36/lib/python3.6/site-packages/django/conf/init.py", line 176, in init raise ImproperlyConfigured("The SECRET_KEY … -
Wagtail new installation : CSS not working
I tried the official installation guide for installing wagtail locally : first by creating a website second by integrating wagtail into a new website Each time it seemed to work fine functionally but all the CSS was broken (see pic down) I tried to do "manage.py collectstatic", it told me that 2/3 hundred files have been copied, I emptied the cache of my browser, loaded the page again, no change. In the console it seems that the files are sent : [14/Jul/2019 10:16:54] "GET /static/css/welcome_page.css HTTP/1.1" 200 3003 I restarted several times the tutorials from the beginning making sure I do each step exactly as described, nothing changes. When I begin with a new django project, the base django css is working before I add wagtail. I m using Python 3.6.8, Django 2.2.3 and Wagtail 2.5.1. What am I doing wrong ? -

Django allauth google extra_data
I've implemented google authentication using django-allauth, but I'd like to get additional data from the Google API about the user being authenticated. The immediate issue is that the username is being populated as the Google user's first name rather than the account username; however, I'd like to know what I can get from the API and how. I see in the providers->openid section of allauth docs that a extra_data can be specified, but I can't find any documentation on if this can be done for google provider, and if so what extra data can be requested. -
Django auto logged out user on inactivity still display as active user
I'm working on a project using Python(2.7) and Django(1.11) in which I need to display only logged in users for a specific function. I have achieved to log out the user by the following settings in settings.py: SESSION_COOKIE_AGE = 180 SESSION_SAVE_EVERY_REQUEST = True LOGOUT_REDIRECT_URL = 'login' and I need to get active users of type driver which is I'm getting as: def get_all_logged_in_users(): # Query all non-expired sessions # use timezone.now() instead of datetime.now() in latest versions of Django sessions = Session.objects.filter(expire_date__gte=timezone.now()) uid_list = [] # Build a list of user ids from that query for session in sessions: data = session.get_decoded() print(data) uid_list.append(data.get('user_id', None)) # Query all logged in users based on id list return user_table.objects.filter(id__in=uid_list, user_type='driver') It was working till a few days ago but suddenly stopped working anymore. When I refresh the page after the time SESSION_COOKIE_AGE passed it redirected to the login page which is perfect but in the database, the is_active for that user is still True and it's still displaying in the get_all_logged_in_users. How can I solve this issue? -

Displaying fixed ForeignKey fields inline in Django/Django-Admin
I have a model that looks like this: class Order(models.Model): # [...some scalar fields...] lens_right = models.ForeignKey(Lens, on_delete=models.CASCADE, related_name='lensright') lens_left = models.ForeignKey(Lens, on_delete=models.CASCADE, related_name='lensleft') with Lens being another model class with a couple of CharFields (and a backlink to the corresponding Order object since Django demanded it). So there are supposed to be always exactly two Lens objects per Order object. Now, in Django Admin, these Lens fields are treated like ordinary foreign key objects, i.e. I get a select dropdown that lets me choose an existing Lens object. However, what I really want is to enter the Lens objects' values directly in an inline form with text fields. A lot like a TabularInline or StackedInline admin model displays it, but inline as ordinary fields would be and accounting for the fact that there are exactly two Lens objects, never more and never less. How can I achieve this? And is this the most suitable design, or is there a better one in your opinion? Any other hints are welcome as well. Thanks. -
Django2/Python3 : Django raises a TypeError when sorting dict()
i am building an e-comerce website and i have to filter products by price, there are a lot of relations in place so i'll get straight to my point. i fetch the Queryset then create a dict with it. then i sort the dict by values using sorted() sorted() works perfectly and i get the output that i need. But if 2 products have the same price it raises a TypeError ( maybe because of 1>1 == False i think) : print(d) {<Product: Product 1>: Decimal('10.00'), <Product: Product 2>: Decimal('10.24'), <Product: Product 3>: Decimal('10.16'), <Product: Product 4>: Decimal('10.00')} sd = sorted((v, k) for (k, v) in d.items()) TypeError: '<' not supported between instances of 'Product' and 'Product' I have tried the same scenario with plain python and no errors are raised so i assumed, this is a Django related error. So, how can i counter this Error in my Except Block in my Django project ? -

PostgreSQL Full Text Search Accuracy

Django multiple calendars
For my app, I have to manage a different calendar for each user. I found some django apps that provide calendar managing system but none that I found provided an option for multiple calendars. I will have to open a new calendar for each new user. I can might use one calendar and tag somehow each event for a user but I think there might be a better way to handle this. Separating the calendars will be easier to manage in my opinion. Doe's someone have a recommendation for an app that already does it or if not, a recommendation how to approach it? Thanks a lot, Itai -

Django TestCase multiple object with for foregin key
I am going through trouble writing a TestCase for the last few days and that is creating multiple objects and passing it related field to compare.

How do I expose Wagtail search in a Django Graphene query?
Given the general structure: class Article(Page): body = RichTextField(...) search_fields = Page.search_fields + [index.SearchField('body')] class ArticleFilter(FilterSet): search = SearchFilter() class Meta: model = Article fields = ['slug'] class Query(ObjectType): articles = DjangoFilterConnectionField(ArticleNode, filterset_class=ArticleFilter) I thought to create a "SearchFilter" to expose the wagtail search functionality, since I ultimately want to perform full text search via graphql like so: query { articles (search: "some text in a page") { edges { nodes { slug } } } } "search" is not a field on the Django model which is why I created a custom field in the Django FilterSet. My thought was to do something like: class SearchFilter(CharFilter): def filter(self, qs, value): s = get_search_backend() return s.search(value, Article) # not sure how to get the model? The search returns a DatabaseSearchResults instance rather than a QuerySet so the endpoint fails. Obviously one way to get this to work would be something like: return qs.filter(pk__in=[r.pk for r in s.search(value, Article)]) however, I'm curious if there's a better pattern that's more efficient. Should the "search" be moved outside of the FilterSet and into the Query/Node/custom connection, and if so, how can I add an additional field to "articles" to see it as the … -

Django Post Signal on some remote DB
I have two different projects Project1 settings default - project 1 database db2 - project 2 database project2 settings default - project 2 database What I did to use serializers, models of project 2, etc in project 1 . I copied the complete app from project 2 to project 1 and registered the model in settings.py and also removed the migrations folder so that any time I makemigrations in project 1 shell it does not create any migrations for project 2 apps in (project 1 and thus migrating wont add any models of project 2 in project 1 ). Now the problem I am facing is I have to use post_save signal on model of project 2 app that I imported in project 1. and get notified in project1 @receiver(post_save, sender=Project2Model) def project2model_save_hook(sender, instance, created, **kwargs): print(created) this will work only when this signal is present in project 2 but not in project 1. In project 1 this is never called when object is created in default db of project 2 or db2 of project 1 How should I proceed?
