Displaying Django page views in my detail page
I want to display the number of times a page have been viewed in my details page. I also want to increment the pageview by 1 anytime the page is anytime the page is loaded. I have a code that does but it also updates my DateTime attribute.

Having a problem redirecting with the correct pk value in django
So, I am having trouble redirecting using other_user pk. I can't figure out to pass that pk in. I am either passing request.user pk, or I am getting a 'local variable 'other_user' referenced before assignment' error. I can pass other_user into my template, but , I don't how to combine the href link WITH the button to submit the form. I wonder if that's even possible? I did try doing it via the redirect method with other_user.id, but I can't. So, basically I am getting the other_user when I query for it, but I don't know how to pass it to my redirect so it take my user where it needs to go. How would I go about solving this problem? views.py/message def message (request, profile_id): if request.method == 'POST': form = MessageForm(request.POST) if form.is_valid(): form.save() return redirect('dating_app:messages') else: conversation, created = Conversation.objects.filter(members = request.user).filter(members= profile_id).get_or_create() other_user = conversation.members.filter(id=profile_id).get() form = MessageForm({'sender': request.user, 'conversation': conversation}) context = {'form' : form, 'other_user': other_user } return render(request, 'dating_app/message.html', context) message.html <form method="post" action="{% url 'dating_app:message' user.id %}" class="form"> {% csrf_token %} {% bootstrap_form form %} {% buttons %} <button name="submit">login</button> {% endbuttons %} <a href="{% url 'dating_app:messages' other_user.id %}">Start messaging </a> <input … -
Guessing Game where players have to correctly guess the name of a specific NBA player given their image (Python)
I would like to create a game for my friends where we are given a random NBA player's head shot and we would have to guess his name correctly. I want to be able to display a wide range of players, including mainstream players and even obscure players. Each correct guess would score more points and whoever has the most points wins the game. I plan on using this website to get all the head shots that I need: (https://sportradar.us/2018/10/nba-headshots-now-available/). I am a beginner in Python and would like some ideas on where to even start. What frameworks should I use? I have dabbled in Django and could imagine creating a web app for this game. I've tried looking up similar tutorials but mostly I've only found basic number guessing games. I don't need a complete solution, maybe just some ideas on where to start so I can figure out the rest. Any advice or resource is appreciated! -

I have a form: class FormFood(forms.Form): CHOICES = [ (1,'Yes'), (2, 'No')] response = forms.ChoiceField(widget=forms.RadioSelect, label="Would you like some pasta, bread or rice?", choices=CHOICES) It appears like this in my browser: The problem I would like 'pasta', 'bread' and 'rice' to appear on different lines with bullet points like this: Would you like: Pasta Bread Rice What I've tried Adding \n in the label text and skipping a line using 'enter'.

Django - What is the best approach to handle multiple user types...and route the HTML pages based on this?
I'm making a small test project with below user types: School Admin, Teacher, Student, Parent. And each user type will have different Permissions like School Admin has full access... Parents can only view their Childern's Activity. Teacher can see all students but can add / edit marks for their respective students only. Teachers can setup Exam etc.. Students can take exam and submit the exam, but cannot edit / add any other information. Just can edit his profile detail. Approach 1: Do i need to create a Custom User calss and apply to each user type (ie one Custome Class.. and 4 user type calss).. and similarly have 4 different view and html pages? Approach 2: Just have one custome class and have an field with UserType which will have the have as "SchoolAdmin", "Teacher", "Student","Parent".. and one view and html (as the data page would remain same and only data record will restrict), and somehow identify the User Type in View, and filter the record? Definately some view or html pages will be specific to one user type only which is i am able to handle, the issue is to use same view / html page to handle all … -
Django: validation of restricted Foreign keys forms in Mixins Class views
Context: how I handled foreign keys restrictions on GET I have some trouble validating this form: class RecordConsultationForm(forms.ModelForm): class Meta: model = Consultation fields = ["fk_type", "fk_client", "duration", "date"] def __init__(self, *args, **kwargs): self.user = kwargs.pop('user', None) super(RecordConsultationForm, self).__init__(*args, **kwargs) self.fields['fk_client'].queryset = Client.objects.filter(fk_owner=self.user) # <=====HERE The queryset restricts the available clients to users. Pretty effective, I just had to add the following to get_context_data(): @method_decorator(login_required, name='dispatch') class BrowseConsultations(BrowseAndCreate): template_name = "console/browse_consultations.html" model = Consultation form_class = RecordConsultationForm success_url = 'browse_consultations' def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['form'] = self.form_class(user = self.request.user) #<=====HERE return context Form validation on BrowseConsultations Despite what I added in get_context_data(), form data on POST does not seem valid, as if user were None (so it seems): Invalid fk_client: Select a valid choice. 2 is not one of the available choices. Maybe get_context_data() was not the proper place to set the user? Is there a way I could tweak the form in post()? Is it the proper way to do it?

Multiply two fields together in django database

Get Item from Django Annotated Queryset With Dynamic Database Functions
I'm encountering something unexpected, and I'm sure it must be a simple solution. I'm trying to use the CUME_DIST() function to annotate a django SQL query. This part is working fine and giving me a proper output. The challenge I'm having is, when I try to fetch a specific item from the annotated queryset using .get(user=request.user) it will give me back the correct item, but the annotated column seems to be re-evaluated. I want to get the item with the same annotated value as in the original query. Note that I can access this correctly with index notation (ex: annotated_queryset[10] gives the correct output for item at index 10), but I'm not sure at which index the desired item will be. Example of my code: annotated_queryset = Profile.objects.annotate(score_cume=RawSQL(""" CUME_DIST() OVER ( ORDER BY score ) """, ())) Above gives me the correct queryset. user_profile = annotated_queryset.get(user=request.user) print("score cum : ", user_profile.score_cume) Printing out the above always gives 1.0 because (I believe) it's evaluating the score_cume filed against the one object it's retrieving. How can I retrieve this object by request.user from the original annotated queryset and keep the annotated value? FWIW: I'm using postgres with django -

Retrieve data from external API and display in django admin
Rather than querying a local database I would like to use an external API to retrieve the data to display in the django admin. For simplicities sake I have a model, and plan to retrieve a list of names from the API: class Person(models.Model): first_name = models.CharField() last_name = models.CharField() class Meta: managed = False As it is not managed it therefore does not create the person table. What is the order of functions I must override in ModelAdmin to Perform the API call instead of the database lookup Output the data to a default table in the admin (with first name and last name) Disable functions such as to add (as this will just be a lookup table) Use the django admin search to query the external api - ie. perform a new request and display the new data. -

Django I want to limit user voting to once per 24 hours but I limited it per article and not per user

I am working on a website (django) that I uploaded online with heroku. Everything worked fine until I had to make a change in my views.py. Now when I do: - git add . - git commit -m "smtg" - git push heroku master It tells me that nothing change but I made some changes, it seems like it cannot see those. When I try git init it tells me " Reinitialized existing Git repository in C:/Users/Loic/Documents/my_site2/.git/ " Could you please help me it is a school project. Thank you
