Django - Redirect uppercase urls to lowercase
In my Django apps, I have many urls including /(?P<project_name>[_\w]+)/. The project_name is defined by users and it is an attribute of the Project model. I've added a validator on the project_name to check if it's lowercase. So new names are all lowercase but some old names include uppercase characters. I would like to change all the names stored to make them lowercase but at the same time, I don't want users to get an error when trying to access to one of the url with the old project name including uppercase characters. As I have many urls and many views, I don't want to update each to manually .lower() the project_name. Is there a way to redirect all urls including /<project_NAME>/ to /<project_name>/? -
How to use Prepend_WWW in DJango
I am facing issues in a project, my site opens with www, but doesn't load if that part is missing. I read about PREPEND_WWW= True (since if user types just domain, redirect to www.domain.com which works) in settings.py on django, but that just doesn't work. I have enabled CommonMiddleware too. Any other thing that can be done to solve?. Please help -
How to change a form dynamically?
I have two models, Company andEmployee. I would like that when the user selected the company, the employee data would be set dynamically in the employee form because both forms will be shown on the same page. So initially on the page I have the form to select the company and immediately after the selection the data of the employees linked to the company appear to the user. I made the forms like this: class CompanyForm(ModelForm): class Meta: model = Company fields = ['nome'] class EmployeeForm(ModelForm): class Meta: model = Employee fields = ['nome'] def __init__(self, *args, **kwargs): super(EmployeeForm, self).__init__(*args, **kwargs) self.fields['nome'].queryset = Employee.objects.filter(company = CompanyForm.cleaned_data.get('nome')) But I get the following error: 'CompanyForm' object has no attribute 'get' Is it possible to change one form immediately when the other is changed (on the same page) without submitting to Django? -
Http request between two containers
I am creating a web service which uses react for the frontend and django REST for the backend. Both are running in separate docker containers. My docker-compose file looks like this. services: db: image: postgres volumes: - ./config/load.sql:/docker-entrypoint-initdb.d/init.sql environment: - POSTGRES_DB=postgres - POSTGRES_USER=postgres - POSTGRES_PASSWORD=postgres web: build: . image: gudmundurorri4/hoss-web command: python manage.py runserver 0.0.0.0:8000 volumes: - .:/code stdin_open: true ports: - "8000:8000" depends_on: - db frontend: image: gudmundurorri4/hoss-frontend stdin_open: true ports: - "3000:3000" depends_on: - "web" Both the web and frontend containers work fine. The backend works when I open it in the browser and when I execute a get request to http://web:8000 from within the frontend container I get the correct response. However when I execute a GET request from my react app using the same address (http://web:8000) it always fails with the error net::ERR_NAME_NOT_RESOLVED -

Django Form Modification with populated value set
I have a problem with this Lead Form. When the user create a lead, he assigns it to a customer. I got the list of customers from the init that retrieve the user associates and build the customers list for my user and his associate. This works fine during the lead CREATION. Unfortunately, when the user wants to edit the lead, I can see the customer id in the pre-loaded form from the lead instance, but it is not pre-selected on the screen. my class LeadForm class LeadForm(forms.ModelForm): def __init__(self, *args, **kwargs): self.user = kwargs.pop('user', None) super(LeadForm, self).__init__(*args, **kwargs) userutils = UserUtilities() associated_users = userutils.get_associated_users_for_customer_module(self.user) self.fields['customer'].queryset = Customer.objects.filter(creator__in=associated_users) team_members = userutils.get_associated_users(self.user) self.fields['assignee'].queryset = team_members customer = forms.ModelChoiceField( queryset=None, label="Customer Email", required=True, widget=forms.Select(attrs={'class': 'form-control select2 select2-container--custom', 'style': 'width:20%'})) and here it is what I obtain instead of the existing customer -

Returning a user with a list of the groups he belongs to in Django Rest API
I'm writing an API and I want to return a list of users along with the groups each user belongs to. I'm fairly new to Django and I'm stuck.

Thanks in advance. -

Give specific permission per user when signing up
I am using allauth for registering users and I would like to give permissions to users automatically after they created a local account or using social login. A good example would be only 1 user to be able to create posts and comments whilst the rest of the users to be able to only create comments. Looking around I have seen that you can create Groups and through those you can give certain permissions, is this the right way to handle this? Or are there some better avenues worth exploring? Many thanks. -
