Get sum of the salary for each user
I am on a django project where the admin assigns work to users by uploading the work to each user, and the user can only see the job they have been assigned. I want a way to get the total amount for all the work the user have done by the end of a month. I have a model Work, and it has a field Pay_Amount, which is the amount for one job, I want a way to add the Pay_Amount of only one user per month. I already have the total amount to pay all the users, I just want the amount to pay a single user for all the jobs he/she has done for one month... Please assist... -

Django Channels message read and unread
I am new to django channels and trying to build a chat app, I met some trouble in developing read and unread functioning, I hope you can give me a hand. chat consumer has a very simple structure: room name chat_1 is for user 1 to receive message. whoever connects to it, can send message to user 1, and database save method is defined in consumer which takes self.scope["user"] as sender, and self.room_name as receiver to create message record and mark it as unread user has a friend list, by clicking on the name, load all messages, meanwhile mark all messages to read, I did this by ajax function rather than ws as user click away from talking target. but here is one scenario, where two user is on each other's page and does not click anyone else, I need to init the message with read already when creating to database. let's say user_1 is talking to user_22, user_1 connect to many ws, but currently facing ws_22 to send message to user_22. In the receive method, how can I determine whether user_22 is currently facing ws_1 which waiting for the message? by saying facing, I does not mean connect to … -
django-tenants basics: SHARED_APPS vs TENANT_APPS
I am using django-tenants for a multi-tenant app. In the docs it talks about setting up SHARED_APPS and TENANT_APPS. SHARED_APPS is a tuple of strings just like INSTALLED_APPS and should contain all apps that you want to be synced to public If I want an app (e.g. django.contrib.auth) to be accessible on both the public schema and shared schema, do I include it only in the SHARED_APPS or do I need to include it in both SHARED_APPS and TENANT_APPS? "SHARED" would imply that everything in this list is accessible via all tenants and the public schema, but the docs seem to imply otherwise? -

Django form not saving - cannot identify problem with code
Trying to save the below form, but it's not saving. The traceback doesn't identify any problem, and print(form.errors) doesnt not return any issue. I have the exact same code working for another page. So I am not sure what I am missing here. There has to be a typo, I cannot find it.

Django - Default on multiple radio buttons
I am making an absence control where you select the presence/absence per user through a radio button. This absence control is already working. But right now, when you save the absences and re-open the page, all the radio buttons are unselected so it is not possible to see what was filled in. How can I fix this so you can see in which way the radio buttons where selected?

Django models for questionaire with questions with different answer types
This question is similar to Designing Django models for questions to have different answer types but hopefully more specific. For my particular case I can see different ways for an implementation but I am not sure what a good way would be. I have a base usermodel. Users are presented with a questionnaire which can be the same for different user but can also be different from one user to another and also might be different on different days for a single user. Each questionnaire has different questions and the questions might have different answer types (text, int, etc). At the end I want a list of the questionnaires with answers for a specific user (e.g. of the past week for user X). I guess one way to implement this would be to only have one answer type (text) and let the form handle the validation and let the view handle the rendering with correct answer formatting: class Question(models.Model): question_text = models.CharField() answer_type = models.CharField() class Questionnare(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) questions = models.ManyToManyField(Question, through='Answer') date = models.DateField(auto_now_add=True) class Answer(models.Model): question = models.ForeignKey(Question, on_delete=models.CASCADE) questionnaire = models.ForeignKey(Questionnare, on_delete=models.CASCADE) answer = models.TextField() Maybe another way would be to have different Answer … -

Set Apache to prompt a password for a Django site?
I have a Django wsgi site that I would put online soon. I would rather the site to not be accessible except through an Apache login prompt until it is ready. I investigated and found limited or outdated information about how to do it (which I tried anyway). There is more information to make it work with a plain Apache served webpage and I was able to made it work on my default Apache welcome page, but Django seems less documented in that regard. For example I added something like this in my .conf file: <Directory "/path/to/djangosite"> AuthType Basic AuthName "Restricted Content" AuthUserFile /etc/apache2/.htpasswd Require valid-user </Directory> where /path/to/djangosite is where wsgi.py resides. Password was set in .htpasswd successfully. How are you all doing this? -
Unwanted glassy border outside of background images
I'm using Django, HTML and CSS to build a website to post some pictures, but I'm fairly new. I'm using a <div> with backgound-image style to load picture on a website. For some reason, every picture is loaded with some border radius (even though I don't have any in my CSS) and it has this weird glassy-looking border, some of the pictures also have a black line among some of the borders. Here is how it looks like. My html file: <div class="container"> <div class="photo-grid"> {% for i in image|dictsort:'pub_date' %} {% if i.is_tall == True and i.is_wide == False %} <div class="card" style="background-image:url('{{i.image.url}}')"> {{i.title}} </div> My CSS file: .container { display: flex; justify-content: center; justify-items: center; } .photo-grid { display: grid; gap: 1rem; grid-template-columns: repeat(auto-fit, minmax(240px, 1fr)); grid-auto-rows: 240px; margin-top: 75px; margin-bottom: 3vw; width: 1500px; } .card { display: flex; flex-direction: column; justify-content: center; align-items: center; height: 100%; width: 100%; overflow: hidden; background-size: cover; background-position: center; background-repeat: no-repeat; } I have no idea what could be wrong with it. I tried deleting random lines of CSS, but nothing seemed to be working. -

What is the most Django-appropriate way to combine multiple database columns into one model field?
I have several times come across a want to have a Django model field that comprises multiple database columns, and am wondering what the most Django way to do it would be. Three use cases come specifically to mind. I want to provide a field that wraps another field, keeping record of whether the wrapped field has been set or not. A use case for this particular field would be for dynamic configuration. A new configuration value is introduced, and a view marks itself as dependent upon a configuration value, redirecting if the value isn't set. Storing whether it's been set yet or not allows for easy indefinite caching of the state. This also lets the configuration value itself be not-nullable, and the application can ignore any value it might have when unset. I want to provide a money field that combines a decimal (or integer) value, and a currency. I want to provide a file field with a link to some manner of access rule to determine whether the request should include it/a request for it should succeed. For each of the use cases, there exists a workaround, that in each case seems less elegant. Define the configuration fields … -

I want to click submit button which would trigger post request and view would create new user. view.py def index(request): form = forms.RegisterForm() context = { 'form': form } if request.POST: print('post') if form.is_valid(): print('valid') form.save() email = form.cleaned_data.get('email') raw_password = form.cleaned_data.get('password') account = authenticate(email=email, password=raw_password) print('authenticate') login(request, account) return redirect('home') else: print('not valid') context['registration_form'] = form else: form = forms.RegisterForm() context['registration_form'] = form return render(request, 'index.html', context) html <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Document</title> </head> <body> <form method="post"> {% csrf_token %} {{ form.as_p }} <button type="submit">Submit</button> </form> </body> </html> forms.py from django import forms from django.contrib.auth import get_user_model from django.contrib.auth.forms import ReadOnlyPasswordHashField User = get_user_model() class RegisterForm(forms.ModelForm): """ The default """ full_name = forms.CharField(max_length=30) password = forms.CharField(widget=forms.PasswordInput) password_2 = forms.CharField(label='Confirm Password', widget=forms.PasswordInput) class Meta: model = User fields = ['email'] def clean_email(self): ''' Verify email is available.

PyCharm doesn't recognize user instance when using custom user model in Django
I have a custom user model in my Django project and when I create an instance of request.user in my views PyCharm doesn't seem to recognize the user instance correctly. The available methods/attributes suggested by PyCharm still point to the built-in Django user model but not to my new one. Is there any way to set this up properly? Example: # settings.py AUTH_USER_MODEL = 'user.UserProfile' # models.py custom user model class UserProfile(AbstractBaseUser, PermissionsMixin): # Email and name of the user email = models.EmailField(max_length=255, unique=True) name = models.CharField(max_length=255) # Privilege and security booleans is_staff = models.BooleanField(default=False) is_superuser = models.BooleanField(default=False) is_active = models.BooleanField(default=False) email_confirmed = models.BooleanField(default=False) # Company on whose behalf the user acts on company = models.ForeignKey('company.Company', on_delete=models.CASCADE, blank=True, null=True) objects = UserProfileManager() USERNAME_FIELD = 'email' REQUIRED_FIELDS = [] def email_user(self, subject, message, from_email=None, **kwargs): """Send mail to user - Copied from original class""" send_mail(subject, message, from_email, [self.email], **kwargs) def __str__(self): return self.email # views.py def render_dashboard_benefits(request): # Get current user instance current_user = request.user # Typing... current_user.company # Pycharm suggests 'first_name' and 'last_name' depending on the initial user model # but not e.g. "email" or "company" according to the new user model return render(request, 'test.html') I'm using the paid PyCharm …
