Trouble Using Django Shell on PythonAnywhere
I am experimenting with Django Shell on PythonAnywhere. I imported a module and run help() on it. The help text is displayed, but I can't find a way to get back to the prompt. It shows (END) at the end of the help text instead of the prompt. Ctrl + Z completely closes the shell, which is not what I want. -

Django: 'SessionStore' object has no attribute 'session'

Dynamic adding apps to Django
I'm building a backend with some core-functionality app (which means, of course, a single DB for the app). I'm looking for elegant way to create app for every new customer by "copying" some template (basic) app to be able modify every's customer app with specific customer's requirements. For ex., I have some basic StoreApp in Django. It could have some basic features, models etc. Now, when some new customer wants to sign up, I want dynamically (not manually) create additional copy of the existing StoreApp (of course, under different name and its own DB), make initial migration for it, register it in the settings and so on. Lately, I want to customize this new app according to the customer's requirements. I'm just looking for a way to separate code maintenance for every existing app, but, as I mentioned before, not to create every app manually. Any elegant way to do it? Some existing plugin for Django? Thanks in advance, Efi -
django not a callable issue
Coming across the error below, not really sure what is wrong. There was phone field missing in the modal which I did not notice before I ran the python manage.py migrate.

Django - How to update form values without clicking?
I am trying to figure out how to update a form input value into another division in the same html file, without clicking, I was thinking about running views periodically(in a sense of polling), but I just need to update the values, when they change in the input field. I tryed to simplify the code below as much as possible. Is it possible using the current layout, or will I have to drop everything and switch to a jQuery approach? forms.py class Entry(forms.Form): quantity = forms.CharField(label = '', required = True, widget forms.TextInput( attrs={'placeholder': 'Quantity','class':"form-control mr-sm-2"})) views.py def index(request): form = forms.Entry() if request.method == 'POST': form = forms.Entry(request.POST) if form.is_valid(): print("Validation Successful") quantity = form.cleaned_data['quantity'] return render(request, 'index.html', {'form':form, 'Quantity':quantity * 2}) index.html <form method = "POST" class="form-inline" id = "myForm"> {{ form }} {% csrf_token %} <button class="btn btn-outline-success my-2 my-sm-0" type="submit" id="but" >+</button> </form> <div> {{Quantity}} </div> Thanks Jaime -
Django 2.1 Test Issue
first of all thank you for your time and sorry about my english. Im learning Django, I had several years developing with python and decided to start to check this Framework. And I'm getting an weird responses. Im writting a TestCase, wich works perfectly outside Test. That is the code: class BoardTopicsTests(TestCase): # Hago las acciones necesarias para empezar el test def setUp(self): self.board = Board(name="Django", description="Django board.") # self.board.save() # Compruebo el status_code 200 def test_board_topics_view_status_code(self): # self.board.save() url = reverse("board_topics", kwargs={"pk":1}) response = self.client.get(url) self.assertEqual(response.status_code, 200) # Compruebo el status_code 404 def test_board_topics_view_not_found_status_code(self): url = reverse("board_topics", kwargs={"pk" : 99}) response = self.client.get(url) self.assertEqual(response.status_code, 404) # Compruebo que resuelve bien el board def test_board_topics_url_resolves_board_topics_views(self): view = resolve("/boards/1/") self.assertEqual( view.func.__name__, BoardTopics.as_view().__name__ ) If I save the board in setUp the method test_board_topics_view_status_code returns 404, if I save the board inside the method it returns 200 and pass the test. I think I'm missing something because I think it have to work saving from setUp method! Please, can somebody help with that? It's just for learning purposes because I want to know whats happening there. If I do print(self.board.id) inside test_board_topics_view_status_code it returns 1 as it suposed to be. Thank you … -
How to integrate cyber-ark with a Django application?
I have a django web application that connects to the production database( Oracle 12g ). I have to use Cyberark for storing the user id and password for connecting to database. Till now my database connection password and user id were mentioned in the DATABASE setting of the settings.py file as clear text. In some other applications( not coded in django ) we have modified the connection string in the tomcat server to connect to the cyberark driver and get the user name password to connect to the database. But I am new to django and dont know where to look for, for the connection string to connect to the database. Which django file picks up the database information from the settings.py file and actually connects to the database? How to integrate cyberark with Django? We are using Gunicorn as wsgi server and nginx as reverse proxy server. We have found a python module named PyArk but haven't found anybody who has used it. If anybody has used it or can answer the above questions, it would be very beneficial for me. -

Django: urls in html form not working correctly
I am building e-commerce website, I have a shopping cart model with items, I want the customer to select the quantity of a certain item they want to buy, this is the reason I am placing everything in a form to later grab the quantity in views.py by request.POST.getlist('quantity') and pass the data to 'Sales:checkout'. But in there I also have button to delete an individual item form the shopping cart (Sales:delete_cart_item) and a button for emptying the whole cart (Sales:empty_cart).

How to get user feedback from Django 2.x ModelAdmin Action
I have an action in a ModelAdmin class. The action may have already been applied to the object selected, so I want to give the user a yes/no popup asking if he/she wants to run the action again. The action is a longish running celery task, but it may be beneficial to run the action again, or it may not. Is there a way to ask the user and get the feedback to make the action do the right thing? Thanks! Mark -
How to use alias in column name in Django

Call property or method of related model in Django
Is it possible to call property or instance method of related object in Django model? One of my models need to access 'parent's' field and show it as it's own property. To check this I've added @property to 'child' model, but unfortunately when trying to call this property in Django Admin I'm receiving: ERRORS: <class 'some_app.admin.AnotherModelAdmin'>: (admin.E108) The value of 'list_display[5]' refers to 'some_app_timestampapplied_operational_mode', which is not a callable, an attribute of 'AnotherModelAdmin', or an attribute or method on 'some_app.AnotherModel'. Simple example: class SomeModel(models.Model): strategy = Charfield(max_length=1, choices=SOME_STRATEGIES) ... class AnotherModel(models.Model): related_parent_model = models.ForeignKey('SomeModel', on_delete=models.CASCADE) @property def applied_strategy(self): return self.related_parent_model.strategy -

django-avatar form location issue
I'm new to django/python and I'm using the django-avatar plugin (https://github.com/grantmcconnaughey/django-avatar) so users can upload images as avatars on our website. I've been trying to debug this issue for a day and I'm not sure what I'm missing. The issue I'm running into is that I copied the "change.html" form into our myaccount.html page and I get the following: "You haven't uploaded an avatar yet. Please upload one now." That's incorrect since I already have an image uploaded and all I want is the proper change form with the input field to appear that populates once an avatar is uploaded. The form I want generated appears properly when I navigate to "/avatar/change/" when i want it to be "/myaccount/change/". Does anyone have any ideas how to solve this issue? Thanks! myacccount.html <p>{% trans "Your current avatar: " %}</p> {% avatar user %} {% if not avatars %} <p>{% trans "You haven't uploaded an avatar yet.

How to add Tags in place of groups to Django posts
Intro: I have a simple project with User, Post and Group. Users can make posts and they have to choose which group the post will belong to. Members (Users) can join and leave groups. If members join a group they see all new articles in that post on their wall. Members cannot create a new Group. They have to select from Existing groups to which their post will belong example: A post on football will belong to the group Football What I want: I want users to be able to link one post to multiple existing groups example: A post on what to eat before a big game.(This post can belong to 3-5 different groups like Football, Soccer, Rugby, Hockey etc). Similar to the Stackoverflow style where you can choose upto 5 tags for your questions. This way this post will belong to all 5 groups. See image below I want to achieve something exactly like this. My Post and Group Models below: class Post(models.Model): user = models.ForeignKey(User, related_name='posts') group = models.ForeignKey(Group, related_name='posts') title = models.CharField(max_length=250, unique=True) message = models.TextField() class Group(models.Model): name = models.CharField(max_length=250, unique=True) description = models.TextField(default='', blank=True) members = models.ManyToManyField(User, through='GroupMember') class GroupMember(models.Model): user = models.ForeignKey(User, related_name='membership') …
