Is it possible to have a hosted Django site use the client's interfaces to create a SSH session with a local privately addressed device
I am trying to learn programming to expand my horizons a bit. I have been creating a Django app that automates several aspects of my day to day job. It would be nice if that Django app could be on a public server for accessibility but also have a view that can initiate an SSH session with various privately addressed devices, mostly to verify network changes were successful. In my mind the script would almost need to run on the client side to use their IP address within the private network but from my understanding, Django is server side. Any advice on how to work around this? -
AssertionError: You need to pass a valid Django Model in UserProfile.Meta, received "None"
I'm adding Django Model to a graphql api using the AbstractBaseUser custom user model. The Admin works fine except that I get an error when trying to access the graphql api, 'You need to pass a valid Django Model in UserProfile.Meta, received "None"' I've tried adding AUTH_USER_MODEL = 'noxer_app.MyUser' to settings, yet it doesn't work In models.py: from django.db import models from django.contrib.auth.models import ( BaseUserManager, AbstractBaseUser ) class MyUserManager(BaseUserManager): def create_user(self, email, first_name, last_name, company, company_reg_no, address, phone, image, password=None): if not email: raise ValueError('Users must have an email address') user = self.model( email=self.normalize_email(email), first_name=first_name, last_name=last_name, company=company, company_reg_no=company_reg_no, address=address, phone=phone, image=image, ) user.set_password(password) user.save(using=self._db) return user def create_superuser(self, email, first_name, last_name, company, company_reg_no, address, phone, image, password): user = self.create_user( email, password=password, first_name=first_name, last_name=last_name, company=company, company_reg_no=company_reg_no, address=address, phone=phone, image=image, ) user.is_admin = True user.save(using=self._db) return user class MyUser(AbstractBaseUser): email = models.EmailField( verbose_name='email address', max_length=255, unique=True, ) first_name = models.CharField(max_length=255, default='') last_name = models.CharField(max_length=255, default='') company = models.CharField(max_length=255, default='') company_reg_no = models.CharField(max_length=255, default='') address = models.CharField(max_length=400, default='') phone = models.CharField(max_length=13, default='') image = models.ImageField(default='noimage.jpg', upload_to = 'profile_pics') is_active = models.BooleanField(default=True) is_admin = models.BooleanField(default=False) objects = MyUserManager() USERNAME_FIELD = 'email' REQUIRED_FIELDS = ['first_name', 'last_name', 'company', 'company_reg_no', 'address', 'phone', 'image'] def __str__(self): … -
Is it recommended to manually redirect sub-domains to an application from the project itself?
We have different types of users whom we'd like to redirect to different views based on the sub-domain in the URL. In our project directory, we examine each and every request for the sub-domain keywords, viz. ut1.domain or ut2.domain. Is this a good solution? If not, please suggest something better. User Type 1 ut1.domain.com/login/ User Type 2 ut2.domain.com/login/ This is how the sub-domains are being planned to be handled. def handle_urls(request): if "ut1.domain." in request.build_absolute_uri(): return HttpResponseRedirect('login/') context = {} return render(request, "home.html", context) The purpose of the sub-domains is to point to different applications in the same project. We expect to add more than a dozen sub-domains in the next few months for various new applications. Thank you for your time reading this. -

Django apache2 KeyError for SECRET_KEY with environment variable
I try to deploy django on a debian server. To protect the secret key i store them in a environment variable. I edit /etc/profile an add: SECRET_KEY="123456789...."; export SECRET_KEY I tested if the variable is set with printenv | grep SECRET_KEY and echo $SECRET_KEY.

Creating a generic search view in Django
I am struggling to create my custom generic view in django to easily create search pages for certain models. I'd like to use it like this: class MyModelSearchView(SearchView): template_name = 'path/to/template.html' model = MyModel fields = ['name', 'email', 'whatever'] which will result in a view that returns a search form on GET and both form and results on POST. The fields specifies which fields of MyModel will be available for a user to search. class SearchView(FormView): def get_form(self, form_class=None): # what I'v already tried: class SearchForm(ModelForm): class Meta: model = self.model fields = self.fields return SearchForm() def post(self, request, *args, **kwargs): # perform searching and return results The problem with the code above is that form will not be submitted if certain fields are not be properly filled. User should be allowed to provide only part of fields to search but with the code I provided the form generated with ModelForm prevents that (for example because a field in a model cannot be blank). My questions are: Is it possible to generate a form based on a model to omit this behaviour? Or is there any simpler way to create SearchView class? I don't want to manually write forms if … -

Django throws a 404 error on all static files while everything seems to be correct
Recently, I added some static files to my project which for some reason threw an error (I can't remember what kind of error.) I removed these files and redeployed but now, when I push my Django project to the docker container, the static files have stopped working all together, while everything seems to be in order. These are the settings I use for the static files: STATIC_ROOT = str(ROOT_DIR("staticfiles")) STATIC_URL = "/static/" STATICFILES_DIRS = [str(APPS_DIR.path("static"))] STATICFILES_FINDERS = [ "django.contrib.staticfiles.finders.FileSystemFinder", "django.contrib.staticfiles.finders.AppDirectoriesFinder", ] I am running the installation in a Docker container, taken from the django-cookiecutter project. I have only changed one thing in the Docker configuration, I removed the Postgres image, since my container connects to an external postgres server. I have tried running manage.py collectstatic, and manage.py collectstatic --clear, to no avail. Also, when I run manage.py findstatic --verbosity 2 css/custom.css, I get a message saying that the file was found, with a list of all the folders searched, which does include the static folders for all my apps inside my project. (There are no static files located outside of default folders.) At this point, I'm pretty lost as to what could be the issue. My best guess would that … -

how to include object into category or subcategory?
I need to make that sort of relations: └───SCOPE01 ├───PROJECT01 │ └───WORKER01 └───WORKER02 Worker can be busy on some project or be free on some scope. Have I chosen the right approach, and how can I do otherwise? #models.py from django.db import models class Scope(models.Model): title = models.CharField(max_length=30) class Project(models.Model): title = models.CharField(max_length=30) scope = models.ForeignKey( Scope, related_name='projects', on_delete=models.CASCADE ) class Worker(models.Model): title = models.CharField(max_length=30) project = models.ForeignKey( Project, related_name='workers', on_delete=models.CASCADE ) scope = models.ForeignKey( Scope, related_name='workers', on_delete=models.CASCADE ) If that is correct, how to limit the simultaneous worker addition into both scope and project? -
DataError value too long for type character varying(100)
I need to make changes to my profiles object at the admin site in Django, but when I click save, I get the error DataError at /admin/profiles/profiles/31/change/ value too long for type character varying(100).

Django database design for dynamic fields with inheritance
I have a problem with my models design. I have various templates and documents that can created from a template. For example: class Templates(models.Model): name = models.CharField(max_length=255) descripton = models.TextField() content = models.TextField() class Meta: abstract = True class TemplateTest1(Templates): class Meta: verbose_name = "Test 1" class TemplateTest2(Templates): class Meta: verbose_name = "Test 2" And these are the document models: class Test1(models.Model): company = models.ForeignKey(Company, on_delete=models.CASCADE) template = models.ForeignKey(TemplateTest1, on_delete=models.CASCADE) class Test2(models.Model): company = models.ForeignKey(Company, on_delete=models.CASCADE) template = models.ForeignKey(TemplateTest2, on_delete=models.CASCADE) Now the templates should contain various variables. If a user create a document he must filled the variables. Some variables should filled from the system automatically. These variables get the data from the database itself. For example the $system_companyname in the content from TemplateTest2 should show the name from the company that the document is created for. For example the content from TemplateTest1 and TemplateTest2 looks like this: --- TemplateTest1 content --- I am from $town and live in $street. Would you like to go? $dropdown-yes-no --- TemplateTest2 content --- Hello $system_companyname, please check the right answer. $checkbox1 I am older than 16 $checkbox2 I have an apartment So the templates contain various variables and types. The document would store … -
