How to populate a select list in a Django Template dynamically using Javascript?
I've recently been learning Django and HTML but I'm completely new to JS and I'm having a go at creating a database display page with a filter menu at the side. For this page I have the following code: Model.py: class Part(models.Model): PartID = models.AutoField(primary_key=True, unique=True) SiteID = models.ForeignKey('Site', on_delete=models.CASCADE, null=True) Comment = models.CharField(max_length=255, blank=True) Subtype = models.ForeignKey('Subtype', on_delete=models.CASCADE, null=True) Location = models.CharField(max_length=255, blank=True) ConnectedTo= models.ManyToManyField('self', null=True) BatchNo = models.CharField(max_length=32, blank=False, null=True) SerialNo = models.CharField(max_length=32,blank=True) Manufacturer = models.CharField(max_length=32, blank=False, null=True) Length = models.FloatField(blank=True, null=True) InspectionPeriod = models.IntegerField(blank=True, null=True) LastInspected = models.DateField(blank=True, null=True) InspectionDue = models.CharField(max_length=255, blank=True) View.py: @login_required(login_url='/accounts/login/') def sites(request, site): siteselected = site warnings = 0 expired = 0 good = 0 PartsAtSite = Part.objects.filter(SiteID = siteselected) TypesList = Type.objects.values_list('TypeName', flat=True).distinct() InspectionList = Part.objects.values_list('InspectionPeriod', flat=True).distinct() LengthList = Part.objects.values_list('Length', flat=True).distinct() LocationList = Part.objects.values_list('Location', flat=True).distinct() ManufacturerList = Part.objects.values_list('Manufacturer', flat=True).distinct() for part in PartsAtSite: if part.LastInspected == None: part.InspectionDue = "Yes" expired = expired + 1 else: Deadline = part.LastInspected + timedelta(days=part.InspectionPeriod) if datetime.now().date() > Deadline: part.InspectionDue = "Yes" expired = expired + 1 elif datetime.now().date() > (Deadline - timedelta(days=30)): part.InspectionDue = "<30 Days" warnings = warnings + 1 else: part.InspectionDue = "No" good = good + 1 part.save() context = { … -

Is it possible to call a class instance by using a variable which has a valid instance name?
I am a newbie in Object Oriented Programming. The problem might sound silly. I have a class named Dogs(). And this class has some instances age, height, weight which are stored in the database. class Dogs(): age=IntegerField() height=FloatField() weight=FloatField() Now if I call the class in a variable and then call the instances with the name inside the class it works fine. dog=Dogs.objects.all()[0] dog.age #works fine dog.height #works fine dog.weight #works fine Now I have another variable which contains one of the instance's name say (temp='age'). I want to call the instance (which is in the variable temp) of the class Dogs using the variable. dog.temp #Does not work Is it possible to get the instance by calling with the variable? If yes then how should I do it? If no then what should be my approach? -

Synonymous many to many model relationship in Django
I'm trying to achieve what you could call a "synonymous" relationship on a self referencing many to many field in Django. Take this model for example (in reality I don't use real words, but category tags instead): class Word(models.Model): name = models.CharField(max_length=30, unique=True) synonymous = models.ManyToManyField('self', blank=True, related_name='synonymous') def __str__(self): return self.name What I want to achieve, is when I have 3 objects, and add any combination of them to the synonymous field, I want all of them to be connected. # Create synonymous words bunny = Word.objects.create(name='bunny') hare = Word.objects.create(name='hare') rabbit = Word.objects.create(name='rabbit') # Set synonymous words to rabbit rabbit.synonymous.set([bunny, hare]) Now when I get the synonymous objects of rabbit, it has what I want: (Pdb) rabbit.synonymous.all() <QuerySet [<Word: bunny>, <Word: hare>]> But when I take the synonymous objects of bunny and hare, they only return rabbit. (Pdb) bunny.synonymous.all() <QuerySet [<Word: rabbit>]> (Pdb) hare.synonymous.all() <QuerySet [<Word: rabbit>]> What I'd like to achieve, is all the synonymous objects, to be "symmetrical". Now, the m2m field is already symmetrical, but it only stops at one object, not all given synonymous objects. So, the ideal result would be this: # Create synonymous words bunny = Word.objects.create(name='bunny') hare = Word.objects.create(name='hare') rabbit = Word.objects.create(name='rabbit') … -

How to create Django models with ManyToMany relation with tables in different PostgreSQL schemas, one model using just part of unmanaged table
I have a Django application which works just fine. Problem is that it needs to be migrated and that brings some changes. Whole application used to be in PostgreSQL schema intake. Problem is with following models. class Authority(models.Model): id = models.IntegerField(primary_key=True) code = models.IntegerField() name = models.CharField(max_length=255) class Doc(behaviors.Timestampable): id = models.IntegerField(primary_key=True) authorities = models.ManyToManyField(Authority, related_name="docs", ) I need Authority model to use existing table named authority_list. Table is in different schema named lists and it contains many columns. I need only three of them. Table is used by other apps too and is used only for reading.

Table 'django_migrations' already exists after dropping database

How many ways we can save values from Django form to Database
I have started learning Django recently using a Udemy course. While going through the course instructor asked to save values from a Form to database. After searching on the internet I figured out how to put form values into database and everything is working fine. Below is my views.py and forms.py files. forms.py class FormName(forms.Form): fname = forms.CharField( label="First Name") lname = forms.CharField(label="Last name:") email = forms.EmailField() verify_email = forms.EmailField(label='Verify Email:') def clean(self): all_clean_data = super().clean() email = all_clean_data['email'] vmail = all_clean_data['verify_email'] if email != vmail: raise forms.ValidationError("Check the emails") views.py def signup(request): form = forms.FormName() if request.method == 'POST': form = forms.FormName(request.POST) if form.is_valid(): post = User() post.fname=request.POST.get('fname') post.lname=request.POST.get('lname') post.email=request.POST.get('email') post.save() return render(request,'third_app/greet.html') else: return render(request,'third_app/oops.html',{'form':form}) return render(request, 'third_app/signup.html',{'form':form}) Now coming to question, the instructor is using meta class to store the form values to the database. Below are his forms.py and views.py files. I am curious about what is the difference between my method and the instructor's. forms.py class FormName(forms.ModelForm): class Meta(): model = User fields = 'all' views.py def signup(request): form = forms.FormName() if request.method == 'POST': form = forms.FormName(request.POST) if form.is_valid(): form.save(commit=True) return render(request,'third_app/greet.html') else: return render(request,'third_app/oops.html',{'form':form}) return render(request, 'third_app/signup.html',{'form':form}) Thanks. -

Filtering for the Infinite Scroll list does not work - Django, Ajax

Need to get the output in the same page (using django model forms with ajax)
I've tried to reinvent a situation, I've faced recently with a simple example, as follows: I'm new to using ajax with django and this is what I'm trying to do.. I have a single page ('home') and there are two buttons Form1 and Form2; clicking either one of the buttons executes an ajax call and gets it's corresponding form without refreshing (I'm able to pass a get request properly using jquery function with ajax call to display it on the 'home' page itself, without refreshing). It looks like this: Each of those select fields are pre-populated with django model values thorugh Model.object.create(name=name) in the IDLE, and have only one field(besides the pk id). If I select a value from either of both dropdowns and hit process, it should display the length of the selected string, without refreshing the page (just as how the page doesn't refresh while switching the forms) ----> This is where I'm exactly struck and I know the approach I'm using is wrong, but not sure on how to correct it. Can someone please help me in completing the intended purpose of this django app. Sorry for the pasted length of the whole code; for helpers' convenience …
