django-formtools, saving data between form steps
I am trying to create a multi-step form wizard using django-formtools. I have a main model called Report and several ModelForms as follows: class ReportFormP1(forms.ModelForm): class Meta: model = Report fields = [ 'company', 'address_line_1', 'address_line_2', 'responsible_person', 'person_consulted', 'assessor_name', 'previous_assessment_date', 'review_date', ] # section 1 class ReportFormP2(forms.ModelForm): class Meta: model = Report fields = [ "premise_num_floors", "premise_floor_area", "premise_occupancy", "premise_occupancy_comments", ] in my views, I have created the following view: class ReportWizardView(SessionWizardView): template_name = 'reporting/report_create2.html' form_list = [ReportFormP1, ReportFormP2] def done(self, form_list, **kwargs): return render(self.request, 'done.html', { 'form_data': [form.cleaned_data for form in form_list], }) And my relevant template looks as follows: {% extends '_base.html' %} {% load static %} {% load i18n %} {% load crispy_forms_tags %} <!-- templates/home.html --> {% load socialaccount %} {% block title %}Create a report{% endblock title %} {% block extra_css %} {{ wizard.form.media }} {% endblock extra_css %} {% block content %} <div class="container"> <h1>Create a report</h1> <p>Step {{ wizard.steps.step1 }} of {{ wizard.steps.count }}</p> <form action="" method="post"> {% csrf_token %} {{ wizard.management_form }} {% if wizard.form.forms %} {{ wizard.form.management_form }} {% for form in wizard.form.forms %} {{ form|crispy }} {% endfor %} {% else %} {{ wizard.form|crispy }} {% endif %} <div class="text-center"> {% … -
FileUploadHandler writing on Uploaded File when calling .read()
Does TemporaryUploadedFile (class from UploadedFile) write on the uploaded data? I have an XML file here when reading the whole file it starts off with text like: "b'----------------------------507481440966899800347275\r\nContent-Disposition: form-data; name=""; filename="sampleXML.xml"\r\nContent-Type: application/xml\r\n\r\n". The original XML file does not contain this. I am trying to use ElementTree to read through the Uploaded XML File. But am stuck at this part which keeps causing a syntax error. Not sure if it is the class file who edits the data or Postman (used this to upload the file to my REST API). If I read the XML file directly from my PC by getting the path, ElementTree reads it with no issue. Its only getting syntax error when reading from the Uploaded File. I have tried ElementTree.fromString() and parse(). Issue isn't on the actual ElementTree. Tried opening the Temporary file and reading from there (same issue, where there is a the text specified above is shown). I basically want to know if the Django inbuilt FileUploadHandler write on the data when running .read() or somewhere along the process? class FileUploadView(APIView): parser_classes = (FileUploadParser, XMLParser,) def post(self, request, filename, format=None): print(request.FILES) file_obj = request.FILES['file'] fileHandler(file_obj) return Response(status=204) def fileHandler(file): filepath = file.temporary_file_path() print(file.read()) tree … -
How to use Django ORM for multiple inner joins on nested foreign keys
I would like to do multiple joins on some django models with a filter on one of the joined tables. Here is what the raw SQL would look like: SELECT DISTINCT c.id, c.description FROM public.customer_customerhiernode AS c INNER JOIN public.territory_management_territorycustomer AS tc ON tc.customer_id = c.id INNER JOIN public.territory_management_territorynode AS tn ON tn.id = tc.territory_node_id INNER JOIN public.territory_management_territoryuser AS tu ON tu.territory_node_id = tn.id INNER JOIN public.authentication_user AS u ON u.id = tu.user_id WHERE u.username = %s This is what I've tried so far, it is filtering correctly at territorycustomers, but when I fetch the CustomerHierNode, it gets all of them. users = TerritoryUser.objects.select_related('user').filter(user__username=username) territorycustomers = TerritoryCustomer.objects.prefetch_related(Prefetch('territory_node__territoryuser_set', queryset=users)) customers = CustomerHierNode.objects.prefetch_related(Prefetch('territorycustomer_set', queryset=territorycustomers)) I want to join these tables and get all their fields as a flat dictionary. Is this possible with the ORM? I also want this to be as efficient as possible. -
Can't set virtualenv - problem with source activation.ps1
Fallowing the freecodecamp's django tutorial I'm stack on the very beginning - I can't set up virtualenv. Everything goes great until it's time to make final step - activate virtualenv and download Django. I'm working on Windows 10, and tried a lot of ways to solve it. Everything ends up with to results, but first things first. Here is what i did: Ran powershell as administrator and set up ExecutionsPolicy as unrestricted Create new folder called 'Dev' Inside Dev created another folder for project with virtualenv - everything by command 'virtualenv name of the folder Tried to activate it by "name_of_project's_folder\Scripts\activate" After this I'm getting error which says that I must "source this script". I tried to make path to the Scripts folder and type only activate but it doesn't work. When I tried to type "name_of_project's_folder\Scripts\activate" but with ".bat" added on the end, nothing happens. Like, literally nothing. I really hope for making this work because I'm slowly getting frustrated coz of tons of research I made today nad a lot of blind tries to solve this. Python was downloaded via powershell and pip if it's important. -
Django: How can I access and display details about the single "child" in the one-to-many relationship?
I have two models - the Company and Department. The Company can have many Departments - this is all connected with Foreign Key and works as expected. I have URLs and templates/views nicely setup and I can add the Company and then I can add Depratments to it. I am also able to access and create new Departments and assign them to the Company. To see, say 5 last companies I have in the system I use this: class IndexView(generic.ListView): model = Company template_name = 'company/index.html' context_object_name = 'latest_company_list' def get_queryset(self): """Return the last five created companies.""" return Company.objects.order_by('company_name')[:5] And here are the models from models.py class Company(models.Model): company_name = models.CharField(max_length=200) company_dba = models.CharField(max_length=200) class Meta: verbose_name_plural = "companies" def __str__(self): return self.company_name # on submit click on the company entry page, it redirects to the url below. def get_absolute_url(self): return reverse('company:index') class Department(models.Model): company = models.ForeignKey(Company, on_delete=models.CASCADE) dept_name = models.CharField(max_length=200) dept_code = models.IntegerField(default=0) def __str__(self): return self.dept_name # on submit click on the department entry page, it redirects to the url below. def get_absolute_url(self): return reverse('company:index') My urls.py file looks like this app_name = 'company' urlpatterns = [ # Company management views path('', views.IndexView.as_view(), name='index'), path('<int:pk>/', views.DetailView.as_view(), name='detail'), path('add/', … -
Factory-boy / Django - Factory instance not reflecting changes to model instance
I am writing tests for a website I'm working on and I'm representing the models with factoryboy Factory objects. However, I've run into some behavior I found somewhat confusing and I was wondering if anyone here would be so kind to explain it to me I'm running a test that contains the following model: STATUS = ( ('CALCULATING'), ('PENDING'), ('BUSY'), ('SUCCESS'), ('FAILED') ) class SchoolImport(models.Model): date = models.DateTimeField(auto_now_add=True) status = models.CharField( verbose_name=_('status'), choices=STATUS, max_length=50, default='CALCULATING' ) For which I've created the following factory. As you can see the status is set to its default value, which I found more realistic than having a randomly selected value class SchoolImportFactory(factory.DjangoModelFactory): class Meta: model = models.SchoolImport status = 'CALCULATING' school = factory.SubFactory(SchoolFactory) @factory.lazy_attribute def date(self): return timezone.now() - datetime.timedelta(days=10) Below you'll see both a (simplified) version of the function that is being tested, as well as the test itself. (I've currently commented out all other code on my laptop, so the function that you see below is an accurate representation) The gist of it is that the function receives an id value that it will use to fetch an SchoolImport object from the database and change its status. The function will be run … -
If possible, how can I automatically create a Many to Many class with a custom create function?
I came across a problem while creating an application. It essentially involves three different classes. The purpose is to create an object containing basic social media information for an artist, as the main model shows: class ArtistSocial(models.Model): artist = models.ForeignKey('core.Artist', on_delete=models.PROTECT) social_network = models.ForeignKey('core.SocialNetwork', on_delete=models.PROTECT) url = models.CharField(max_length=50) created_at = models.DateField(auto_now_add=True) updated_at = models.DateField(auto_now=True) The premise of the challenge I'm faced with is that upon the creation of a new artist, I'll be sent a JSON with all the information I need. However, being quite new to programming applications like this, This makes me confused as to how exactly I need to prepare to properly receive that information and create the class. To me, making a custom create action is the clear solution, but I've tried this in many different ways both in ArtistSerializer and ArtistSocialSerializer. I'll post those two pieces of code here: class ArtistSerializer(ModelSerializer): user = serializers.HiddenField( default=serializers.CurrentUserDefault() ) class Meta: model = Artist fields = ['id', 'user', 'name_alternative', 'labels', 'tags', 'country', 'bio', 'profile_image', 'created_at', 'updated_at'] read_only_fields = ['id', 'created_at', 'updated_at', 'user'] And here's the main one: class ArtistSocialSerializer(serializers.ModelSerializer): class Meta: model = ArtistSocial fields = ['id', 'created_at', 'updated_at', 'artist', 'social_network', 'url'] read_only_fields = ['id', 'created_at', 'updated_at'] Though … -
Django mixin and FormView template confusion with CBV
I'm still a noob at mixins in general so I'm just trying to understand what happens in this code that uses Ajax to submit forms. I've been scouring the docs for a whole day to try to figure out what happens. The code seems to work but I just don't entirely understand why. I still have a lot of question marks on the whole process so if anyone can correct my thinking that would be amazing The AjaxableResponseMixin extends the form_invalid() and form_valid() methods of the FormView to support Ajax requests Why is the Ajax class referring to itself with super()? How does the class know to extend FormView's methods? If the request is not Ajax it returns response What does the response object do/have? Does it show a template? Does it have context for the template? CreatePostView is a child class of the two parent classes that are passed in (AjaxableResponseMixin, FormView) Do the order of the classes in the params have an impact in general and more specifically when calling super()? When CreatePostView calls form_valid() and form_invalid() is it overwriting the Ajax class? If it isn't, what class methods is it changing? If the form is valid then … -

Django: overriding predefined method save() using request data
I'm trying to override the save() method on a Django model so that some fields are automatically filled out.

However, in the current format the request is not "passed" to the model, and I'm not sure how I am supposed to do that. This is what I currently get: name 'request' is not defined -

Django REST Framework requires hashed password to login
Django requires me to send a hashed password to get my JWT token. When I send the following request via postman I get a "CustomUser matching query does not exist" error. { "user": { "email": "myuser", "password": "mypassword" } } I can, however, run the code with the hashed password (after looking it up from the admin) and it returns the correct value.

When we use django template to build a website traditionally,django will handle authentication Automatically, but now I trying to build a Front-and-rear-separation website with django-restframework and vue.js, I don't know how frontend distinguish authentication status. I understand how django authentication works, It set sessionid to cookie, when we send request with cookie django server will know is this request is authenticated, but I think frontend should not be able to access cookie, so I would like to set CSRF_COOKIE_HTTPONLY=Truein django, I can sitll send request with cookie the authentication in django server is still work but how frontend tell the authentication status. what I expect is just like normal website, login or not is showing in the top righthand corner of the page. if login, my user name will be display. if not, a link to login page -
