Is there a good way to deal with multiple forms and models in Django?
I'm building an app in which I have a model with several manytomany fields and some foreignkey fields, and I need a view that allows me to create all in one page and let me enter multiply times for the manytomanyfields, but I don't know how to deal with a lot of forms in the same page/view. main model class Client(models.Model): company_name = models.CharField(max_length=255, blank=True, null=True) payment_method = models.CharField(max_length=64, null=True, blank=True) owner = models.CharField(max_length=100, blank=True, null=True) operation = models.CharField(max_length=50, blank=True, null=True) value = models.DecimalField(max_digits=8, decimal_places=2, null=True, blank=True) currency = models.CharField(max_length=55, null=True, blank=True) address = models.ManyToManyField(Address, blank=True) contact = models.ManyToManyField(Contact, blank=True) relationship = models.ManyToManyField(Relationship, blank=True) attachment = models.ManyToManyField(Attachment, blank=True) billing = models.ForeignKey(Billing, null=True, blank=True, on_delete=models.CASCADE) delivery = models.ForeignKey(Delivery, null=True, blank=True, on_delete=models.CASCADE) author = models.ForeignKey(User, on_delete=models.DO_NOTHING, blank=True, null=True) note = models.TextField(blank=True, null=True) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) def __str__(self): return self.company_name others models class Address(models.Model): address = models.CharField(max_length=256, null=True, blank=True) number = models.PositiveIntegerField(null=True, blank=True) district = models.CharField(max_length=32, null=True, blank=True) city = models.CharField(max_length=32, null=True, blank=True) country = models.CharField(choices=COUNTRY_CHOICES, max_length=64, null=True, blank=True) def __str__(self): return self.address class Contact(models.Model): name = models.CharField(max_length=256, blank=False, null=True) sector = models.CharField(max_length=64, blank=True, null=True) email = models.EmailField(max_length=256, blank=True, null=True) phone = PhoneField(blank=True, null=True) cellphone = PhoneField(blank=True, null=True) role = … -
Create model instance from dict containing different keys compared to model attributes in Django
I am trying to create model/s from an api response. The response received has different keys as compared to the model attributes in our system. I would like to know the best way to create a model from that response. class MyModel(BaseModel): external_id = models.IntegerField(blank=True, null=True) start_date = models.DateField(blank=True, null=True) end_date = models.DateField(blank=True, null=True) def save_to_db_from_external_data(response_data): map_dict = { 'externalId': 'external_id', 'startDate': 'start_date', 'endDate': 'end_date' } if type(response_data) == 'dict': new_model_data_dict = {} for key in map_dict: if key in response_data: new_model_data_dict[map_dict[key]] = response_data[key] MyModel.objects.create(**new_model_data_dict) elif type(response_data) == 'list': new_model_data_list = [] for data_dict in response_data: new_data_dict = {} for key in map_dict: if key in data_dict: new_data_dict[map_dict[key]] = data_dict[key] new_model_data_list.append(new_data_dict) MyModel.objects.create(**(model_data_dict) for model_data_dict in new_model_data_list) The above is the code that I have written. Is this the correct way to do the required task? Or is there any better way in django to achieve the same? -

Django + OWASP ZAP Cross Site Scripting (Reflected) - Is the value attribute of an HTML input tag a risk?
In my Django project, I have a search input in the navbar across most pages on my site. I'm a beginner to OWASP ZAP. After running the scan, one of the high priority alerts (red flag icon) raised was "Cross Site Scripting (Reflected)". In my case, this is my website search form: <form method="GET" id="searchForm"> <input type="text" name="q" id="searchQuery" placeholder="Search..." autocomplete="off" maxlength="100" required=""> </form> if someone searches for javascript:alert(1); in the search box, the value= attribute contains the same. <form method="GET" id="searchForm"> <input type="text" name="q" value="javascript:alert(1);" id="searchQuery" placeholder="Search..." autocomplete="off" maxlength="100" required=""> </form> Is this is a potentially vulnerability or is the input is being sanitized by Django? This form is created using a Django forms.ModelForm: class SiteSearchForm(forms.ModelForm): class Meta: model = Search fields = ('q',) -
How to prepopulate tabularInline fields with different values per-row
I have a ModelAdmin class with an inline of type TabularInline. What I would like is for each row of the TabularInline. What I need to do is to pre-select the select boxes with the available languages so each of them will have one of the languages as a selected value (e.g. row1: English, row2:Arabic, row3: Français, row4: Espanol). Please note that the number of rows is generated based on the count of the available languages. Any suggestions would be appreciated. My code is shown below: admin.py class SectorTranslationInline(admin.TabularInline): model = SectorTranslation form = SectorTranslationForm def get_extra(self, request, obj=None, **kwargs): lang_count = Language.objects.count() return lang_count def get_max_num(self, request, obj=None, **kwargs): lang_count = Language.objects.count() return lang_count class SectorAdmin(admin.ModelAdmin): inlines = [ SectorTranslationInline ] models.py class Sector(models.Model): _name = models.CharField(max_length=255, null=False, default='') class Language(models.Model): name = models.CharField(max_length=255, null=True) name_prefix = models.CharField(max_length=255, null=True) class SectorTranslation(models.Model): lang = models.ForeignKey(Language, related_name='lang_sector_translation', on_delete=models.CASCADE) sector = models.ForeignKey(Sector, related_name='sector_translation', on_delete=models.CASCADE) name = models.CharField(max_length=255, null=False, default='') -
How to make a django field read only for a non staff user in django rest framework

Django Two Factor Auth with custom login
I am trying to add two factor login using the @otp_required decorator from Django Two-Factor Authentication into my custom login. From other posts, it seems like the correct way to do this is create a new view that is extended from two factors Login View so I have views.py from two_factor.views import LoginView from two_factor.forms import AuthenticationTokenForm, BackupTokenForm class testLogin(LoginView): template_name='customLogin.html' form_list = ( ('auth', TestLoginForm), ('token', AuthenticationTokenForm), ('backup', BackupTokenForm), ) urls.py path('test/', views.testLogin.as_view(), name='test') I have also extended my login form to be forms.py from django.contrib.auth.forms import AuthenticationForm class TestLoginForm(AuthenticationForm): username = forms.CharField(max_length=20) password = forms.CharField(max_length=20, widget=forms.PasswordInput) How would I pass the form into a html page and then get that data back through a post command so I can work with the data in another view such as my customView. views.py def customView(request): form = TestLoginForm(request) if (request.method == "POST"): if (form.is_valid()): -
Recover old jupyter notebooks
I had to uninstall everything on my laptop and reinstall including python and jupyter. Now I dnt see any of my jupyter notebooks when I launch jupyter. I am having almost a heart attack! How I can recover my codes in jupuyter? some additional info: This was part of our company transition from legacy company to new company. We basically lost all installed programs as the results of this transition. I know, very stupid but I was not involved in making decisions! -
Django Admin login not working after model change
I changed the username field to email, following this guide. Everything works so far, except for Django Admin Website, which worked before like a charm. No matter what I enter it always displays "Please enter the correct email address and password for a staff account. Note that both fields may be case-sensitive.". This is odd, as I am still able -from my separate frontend- to add and login users. Just the ones created via createsuperuser don't work properly. I went to the shell and it stated the following: >>> from user.models import User >>> User.objects.get(id=1) <User: Firstname Lastname> >>> me = User.objects.get(id=1) >>> me.password 'pbkdf2_sha256$216000$XTRS1jTuNQWA$rvRCMxeYAJVaL1SftNjXBYCxlMiRnHs9uopq4OMh6gM=' >>> me.email 'me@test.test' >>> me.username >>> me.is_staff True >>> me.is_superuser True >>> me.is_active True So this seems to work. But when I do the authenticate method for those credentials, nothing happens. My model looks basically like this and worked before the change: class User(AbstractUser): username = None email = models.EmailField(_('email address'), unique=True) USERNAME_FIELD = 'email' REQUIRED_FIELDS = ['first_name', 'last_name'] objects = CustomUserManager() I tried deleting the database and reading the user, I tried different passwords and usernames (mail addresses). -
trouble with django on git bash. command not found
I've been trying to to start a django project but have been having issues following the usual steps recommend to start a django project, some have been working some have not. For instance: pip django doens't work, throwing the error - bash: pip: command not found, while py -m pip django works. Similary when I try to check if django is installed django --version gives the error bash: django: command not, while this py -m django --version has no issues. So I figured just adding py -m would make all comands work, however when I try py -m django-admin startproject x to try and create my first django file but it gives the error "C:\Users\username\AppData\Local\Programs\Python\Python39\python.exe: No module named django-admin" What can I do to make django-adming work and be able to create a project :( -
Django createsuperuser command not working after switching from username to email
So I changed the Django username field to 'email', which is documented as completely legal here, but after this, the createsuperuser method doesn't work. Of cause I have added the Auth model to my settings and it worked before. This is basically my model currently: class User(AbstractUser): username = None email = models.EmailField(_('email address'), unique=True) USERNAME_FIELD = 'email' REQUIRED_FIELDS = ['first_name', 'last_name'] After migrating the change createsuperuser throws this after every input is entered: XXX\django\contrib\auth\management\commands\createsuperuser.py", line 189, in handle self.UserModel._default_manager.db_manager(database).create_superuser(**user_data) TypeError: create_superuser() missing 1 required positional argument: 'username' I tried moving around this with a custom manager, but it threw new problems plus I would really would like to avoid this. Furthermore, I looked at the source code of the method, but couldn't figure out where this could go wrong. I also reset and deleted the database without luck. -

localhost vs. 127.0.0.1 in regards to CSS
So I've seen a few posts about the differences between localhost and 127.0.0.1 but nothing specifically regarding my question. I am currently creating a Django application which, when run, starts the application on 127.0.0.1:8000. My problem involves updating my CSS files and not always seeing changes when I refresh. Sometimes the changes will display on one of the two but not the other and was curious as to why this may be? I do currently have multiple CSS files as well as bootstrap files which I have downloaded the libraries for. Any general feedback on why these changes occur on one of the two but not the other would be appreciated! -
Django objects.filter vs objects.all
I have a question regarding the filter() and all() methods of django objects. It is not a question which one of the two is preferred, I just noticed an odd (to me) behavior. Because, as it is laid out in Django ORM - objects.filter() vs. objects.all().filter() - which one is preferred? in Django src, both ways should return the same (they both reference the chain() method): See: https://github.com/django/django/blob/0963f184abd96800b76b19a6a181e1b544c7fafe/django/db/models/query.py#L928 And: https://github.com/django/django/blob/0963f184abd96800b76b19a6a181e1b544c7fafe/django/db/models/query.py#L951 So the filter() and all() method should return the same objects. But I recently discovered the following behavior: MyModel.objects.all()[0].update(name="Test") # --> $: AttributeError: type object 'MyModel' has no attribute 'update' # And to check if it indeed has no update method: MyModel.objects.all[0].__dir__() # --> no update() method in returned dictionary but a save method So while above code raises Error, line below would work: MyModel.objects.all()[0].name = "Test" MyModel.objects.all()[0].save() However, if the same object is retrieved by the filter() method, it has the update() method. Why do I get the same object both times but with seemingly different methods added to it? -

Django - get table data from templates into views.py
I am making a restaurant application and currently working on takeaway food functionality i.e. user orders food online.

Why is my django-graphql query returning null, when the property of my model is not?
I am creating a Django application with a GraphQL API (using graphene-django), and I have made the types for my models. However, I have this CompetitorModeType, which is a custom type. The purpose of this is for when I want to access a specific property of a Competitor (or a mode), I can use this type, and in the query, pass the mode a variable. The goal is to pass the Competitor id and the mode I want to access and get it back as response.data.mode or something like that. So it is what I did with the resolver: The problem is that when I do the query, I get the value as null, and I don't why. Here is the query I am doing: As you can see, I am getting null. However, the values are not null, as shown here: And if I do the same query in the Django shell, I don't get null: My theory is that I am not correctly creating the Type. That there is probably a logical error there because the shell is proof that the query works. If anyone knows what is going on, pls help! -
