Specifying user ID in Django
I have this model where I calculate different values based on certain fields. For example, when I calculate the total, I use the field price and * it with the quantity field. When I want to get the margin, I take the calculated total and deduct it from a field in a different class known as sales. What has been hard to implement for me, is how to automatically get the user id, such that, when the deduct function is called, it deducts from that user and not the previous entry. I have been looking for ID vs PK but I not sure how to use them. Please shed some insights. from django.db import models from numpy import array class CowData(models.Model): Product = models.CharField(max_length=20, default="") user = models.CharField(max_length=20, null=False,unique=True) item = models.CharField(max_length=20, null=True) quantity = models.IntegerField() price = models.DecimalField(decimal_places=2, max_digits=10, default=0) total = models.DecimalField(editable=True, decimal_places=2, max_digits=2, blank=True, null=True, unique=False) def __str__(self): return self.user def save(self, *args, **kwargs): self.total = array(self.total) self.total = self.price * self.quantity super().save(*args, **kwargs) class Sales(models.Model): sales = models.IntegerField(default=0, blank=False, null=False) margin = models.IntegerField(editable=True, blank=True, null=True) user = models.ForeignKey(CowData,to_field='user',max_length= 20 ,null=False, on_delete=models.CASCADE, related_name='username') def save(self, *args, **kwargs): self.margin = self.sales - CowData.objects.get(pk = 5).total if self.sales > … -
Why doesn't the MathJax preview show when using ckeditor and Django?
I'm currently trying to create a simple website using Django, with ckeditor for form fields. I would also like to integrate some Mathematics into my forms, hence why I downloaded the Mathematical Formulas plugin for ckeditor. I followed this tutorial to implement the plugin but MathJax doesn't work. This is what I added to my settings.py file CKEDITOR_CONFIGS = { 'default': { 'toolbar':'full', 'height': '400px', 'width': '100%', 'extraPlugins': ','.join( [ 'mathjax', 'widget', 'lineutils', 'dialog', 'clipboard', ]), }, } I copied the MathJax folder I downloaded into my project's static directory. I then refer to this in my models.py file: from django.db import models from django.contrib.auth.models import User from ckeditor.fields import RichTextField class Entry(models.Model): entry_title = models.CharField(max_length=100) #entry_text = models.TextField() entry_text = RichTextField(blank = True, null = True,config_name = 'default', external_plugin_resources=[( 'mathjax', '/static/entries/vendor/ckeditor_plugins/mathjax/', 'plugin.js', )]) entry_date = models.DateTimeField(auto_now_add = True) entry_author = models.ForeignKey(User, on_delete = models.CASCADE) class Meta: verbose_name_plural = "entries" def __str__(self): return f'{self.entry_title}' When I use my form, I can see the mathematical formulas symbol: Math symbol on ckeditor form When I click on it, ckeditor gives me the freedom to type whatever I want into the Tex field: Typing in Tex However, it doesn't give me a preview … -

Python Scripts and Classes outside Django App
Apologies if this is a duplicate question. I tried searching up my question but didn't find anything. I have a Django Project with 3 Django Apps and the project directory looks like this Project |__ App_1 |__ App_2 |__ App_3 |__ views.py |__ models.py |__ scripts |__ class1.py The scripts folder has python scripts that run algorithms using data from the database. I am using the Django Queryset to retrieve data. The class1.py file would look something like this: from App_1.models import table1 . . . When doing that, I get this error: ModuleNotFoundError: No module named 'App_1' Curious, I moved class1.py to the App_1 folder and I got this error. ImportError: attempted relative import with no known parent package I am a bit confused as to why BOTH methods did not work. What would be the best way to go about this? Ideally, I want to setup my scripts so I can just declare an object in a view-based function in App_1/views.py -

How to iterate through an html list and save the rows separately based on the content using django?
I am saving an html list into a database using python. The problem is in the html form I don't want to enter a video for every row. The code to retrieve the form data looks like this: def addworkout(request): if request.method == 'POST': exercise = request.POST.getlist('exercise[]') sets = request.POST.getlist('sets[]') reps = request.POST.getlist('reps[]') rest = request.POST.getlist('rest[]') tempo = request.POST.getlist('tempo[]') notes = request.POST.getlist('notes[]') dateInput = request.POST['date'] video = request.FILES.getlist('video[]') I tried something like this because I want to be able to leave the video row empty on some of the form rows: if dateInput == "" and video: #for x in range(len(exercise)): # workout = userworkouts(exercise=exercise[x], sets=sets[x], reps=reps[x], rest=rest[x], tempo=tempo[x], notes=notes[x], userid=request.user.id, date=date.today(),video=video[x]) #workout.save() elif dateInput == "" and not video: #for x in range(len(exercise)): # workout = userworkouts(exercise=exercise[x], sets=sets[x], reps=reps[x], rest=rest[x], tempo=tempo[x], notes=notes[x], userid=request.user.id, date=date.today()) # workout.save() else: # for x in range(len(exercise)): # workout = userworkouts(exercise=exercise[x], sets=sets[x], reps=reps[x], rest=rest[x], tempo=tempo[x], notes=notes[x], userid=request.user.id, date=dateInput,video=video[x]) # workout.save() that obviously didn't work because I either need to leave them all blank or enter a video for every row. I then tried something like this trying to iterate over it and check each instance like this: for x in range(len(exercise)): if dateInput[x] == … -

Django/Python TemplateDoesNotExist at / base.html
I am currently trying to learn Python and was watching some tutorials on youtube. I had thought of learning how to deploy dashboards to django and came across this tutorial. I was able to follow on the tutorial but when I try to run my code, I am receiving an error [https://i.stack.imgur.com/EkGQx.png][2] I did what was in the tutorial and this is my file and codes [enter link description here][3] Home App URLS.PY from django.urls import path from . import views urlpatterns = [ path('', views.home, name='home') ] Home App VIEWS.PY from django.shortcuts import render def home(requests): return render(requests, 'home/welcome.html') Setting.py INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'home.apps.HomeConfig', ] STATICFILES_LOCATION = 'static' STATIC_URL = '/static/' STATIC_ROOT = 'static' STATIC_DIR = [ os.path.join(BASE_DIR, 'slsuhris/static'), ] Project URLS.PY from django.contrib import admin from django.urls import path, include urlpatterns = [ path('admin/', admin.site.urls), path('', include('home.urls')), ] I have followed tutorial except for the migration using PostgreSQL thinking that it isn't necessary for building a dashboard. Why can't I access the files? Thank you. I am using Python Community Edition. Does having error on the <!doctype html> got to do with this error? https://i.stack.imgur.com/fY5Qb.png [2]: -
