Checkbox booleanfield modelform in Django
So I'm making a to-do list and I made a booleanfield modelform which has attribute "complete". I want that user to check it when it's complete and I tried wriring if task.complete == True cross out the item and it didn't work(it only worked when I checked it from the admin panel). Then I tried form.complete instead of task.complete and it doesn't do anything. models: class Task(models.Model): title = models.CharField(max_length=200) complete = models.BooleanField(default=False) created = models.DateTimeField(auto_now_add=True) def __str__(self): return self.title forms: from .models import * class TaskForm(forms.ModelForm): title = forms.CharField(widget= forms.TextInput(attrs={'placeholder':'Add new task...'})) class Meta: model = Task fields = '__all__' views: def index(request): tasks = Task.objects.order_by('-created') form = TaskForm() if request.method == 'POST': form = TaskForm(request.POST) if form.is_valid(): form.save() return redirect('/') context = { 'tasks': tasks, 'form': form, } return render(request, 'to-do.html', context) html: [![<div class="main-container"> <form method="POST" action="/"> {% csrf_token %} <input type="submit"/> {{ form.title }} </form> {% for task in tasks %} {{ form.complete }} {% if form.complete == True %} <h1><strike>{{task.title}}</strike></h1> {% else %} <h1>{{task.title}}</h1> {% endif %} {% endfor %} </div>] -
Send mail when more than 10 matches are assigned to user in a month
I have two models. A User model and a Match model. A user can subscribe to my service for either 6/12/18 months on any given date. I want to limit a user to a maximum of 10 matches per month. If the user crosses 10 matches in a month, I want to send an alert email. The 10 match quota should reset the following month. How do i achieve this? Following are the models: class User(AbstractBaseUser, PermissionsMixin): email = models.EmailField(verbose_name='email address', max_length=255, unique=True) MembershipStart = models.DateTimeField(blank=True, null=True, verbose_name="Membership Start Date") MembershipLength = models.IntegerField(verbose_name='Length of membership in months from MembershipStart') class Match(models.Model): user = models.ManyToManyField(User, blank = True) name = models.CharField(max_length = 100) created_on = models.DateTimeField(default=timezone.now) -
PyCharm: ImportError: libmysqlclient.so.20 only when I run django app from IDE
I am working on a simple Django app using PyCharm community edition, python 3.9 and ubuntu 20.04. The project's virtual environment is in folder [project root]/venv/ When I start the app from the pycharm terminal window I execute the following commands and everything works fine (no import errors): source ./venv/bin/activate python manage.py runserver When I start the app from the IDE running configuration, I get an ImportError: libmysqlclient.so.20: cannot open shared object file: No such file or directory. Given that the project runs via the terminal, I believe that my python installation and my virtual environment are ok. I guess that this should not happen if the IDE run/debug configuration was using the same virtual environment hosted in [project root]/venv/. Therefore, I suppose the run/debug configuration is not correctly configured, or there is something missing in my paths. I have checked other posts but I could not find a solution. The following screenshots depict my run/debug configuration and the setup of my virtual environment in the PyCharm IDE (also showing the respective packages). Could somebody please guide me? Is there a setting in PyCharm IDE that I should check for? Do I miss something fundamental about how do python virtual … -

django nesting TextField within ArrayField for postgres
Django provides a nice to way to write ArrayFields in PGSql: https://docs.djangoproject.com/en/3.1/ref/contrib/postgres/fields/#arrayfield eg: class Board(models.Model): pieces = ArrayField(ArrayField(models.IntegerField())) I also see other examples using CharField - which I have used in the past and works just fine. Now, I was wondering if I can do the same with TextField like so: class Board(models.Model): extra_array = ArrayField(models.TextField(blank=True), default=list) Is this legit to do this? Are there any gotachas I need to be aware of? None of the examples seem to use TextField and I wondered why! -

Django get all Model Instances that are within 2 hours of timeframe
As a Django beginner I struggle with a very basic problem: Filter a table based on the date difference of two rows. I have the following model: class DataPoint(models.Model): uid = models.CharField(max_length=128) timestamp = models.DateTimeField(auto_now_add=True) and I want to extract data points that have the same UID and are all within the range of e.g. 2 hours. I could of course use something like: DataPoint.objects.filter(uid=uid, timestamp__range=[timezone.now - timedelta(2), timezone.now]) but that would only return everything within the same 2 hour frame from now, but not dynamically given the DataPoint's timestamp. So this data set: (1) DataPoint: 2021-03-07 12:40 (2) DataPoint: 2021-03-07 11:40 (3) DataPoint: 2021-03-07 10:50 (4) DataPoint: 2021-03-07 08:55 would only return (1), (2), (3) with the query above, even though (4) is still considered connected, as it's within a 2h timeframe of (3). Been trying to get this to work with a RECURSIVE RAW SQL, as I thought this was the only way to do it with Django, but it's not working as expected either. WITH RECURSIVE previous AS ( SELECT id, uid_id, timestamp FROM core_datapoints WHERE id = %s UNION ALL SELECT s.id, s.uid_id, s.timestamp FROM core_datapoints s WHERE uid_id = s.uid_id AND (timestamp - INTERVAL '2 … -

How to fix slugs implemented in Django?
I am using django to create a blog where all posts are shown on the home page as well as on pages depending on their subject. While the basics as shown work, I am having great difficulty with the following: For each subject page I would like the url to include ~/subject_slug/ Currently I am getting ~/subject/subject_slug When I eliminate subject/ from urls.py (line 8), I get the desired ~/subject_slug only. HOWEVER, the individual posts cannot now be accessed. Error: Subject.DoesNotExist: Subject matching query does not exist. Line 21 in views.py is pointed to. There I have tried to include either Subject, or subject, in the bracket before subject_slug=subject_slug. Unfortunately that shows: UnboundLocalError: local variable 'subject' referenced before assignment. Attempts with adding subject to the post_detail view have also not worked. For each post I would like the url to include ~/subject_slug/slug/ Therefore I added str:subject_slug/ to urls.py line 10.

Connect uploaded file to a post in Django
I am trying to connect an uploaded document with the related post in Django. The idea is that when a user creates a post (I called it seed in my code), he can upload a document with it if he wants to. I tried using the joint method to do so, but it is not working (either telling me it expects an "str" and not an "int" or telling me the ForeignKey condition is not working). Is there any way to then connect those two classes, and successfully upload a file? Thank you for any help!! Here is what I tried: views.py """ def seed_create(request): if request.method == "POST": seed_form = SeedForm(request.POST) docu_form = DocumentForm(request.POST, request.FILES) if seed_form.is_valid() and docu_form.is_valid(): seed_form.instance.user = request.user docu_form.save() seed_form.save() messages.success(request, 'Your seed was successfully created!') return redirect('seed:view_seed') else: messages.error(request, 'Please correct the error below.') else: seed_form = SeedForm(request.POST) docu_form = DocumentForm(request.POST, request.FILES) return render(request, "seed/create.html", context={"seed_form": seed_form, "docu_form": docu_form}) """ models.py """ def gallery_folder(instance, file): return '/'.join(['documents', instance.seed_related_id, file]) class Document(models.Model): seed_related = models.ForeignKey(Seed,on_delete=models.CASCADE,default=1) description = models.CharField(max_length=255, blank=True) file = models.FileField(default="No file",upload_to=gallery_folder) uploaded_at = models.DateTimeField(auto_now_add=True) def __str__(self): return self.title """ forms.py """ class DocumentForm(forms.ModelForm): class Meta: model = Document fields = ('description', 'file') """
