Streaming a zip file in Python3
In my Django project, I have large zip files I need to send to a user for them to download. These files can be up to 10Gb big at some points. The files are already in zip format, and I don't want to extract them. Instead, I would like to send say 100mb of the file at a time, wait for the frontend to receive them, and then ask for the next 100mb until the file has been completely read. I can handle the collection and download on the frontend, but how can I perform this request in Django? Disclaimer: I'm a frontend developer, and very new to python. -

How to restrict form validation for users under 18 years of age in Django
I have a form that allows users to update their birthday on their profile. I only want the form to validate if the user is at least 18 years of age. Here's what I've tried: models.py class Profile(models.Model): birthday = models.DateField() forms.py from django import forms from datetime import date from .models import Profile class ProfileUpdateForm(forms.ModelForm): birthday = forms.DateField(widget=forms.DateInput(attrs={'type': 'date'})) def clean_birthday(self): dob = self.cleaned_data['birthday'] age = (date.today() - dob).days / 365 if age < 18: raise forms.ValidationError('You must be at least 18 years old') return dob class Meta: model = Profile fields = ('birthday',) views.py @login_required def update_my_profile_view(request): profile = Profile.objects.get(user=request.user) if request.method == 'POST': form = ProfileUpdateForm(request.POST or None, instance=profile) if form.is_valid(): form.save() return redirect('users:my_profile') else: form = ProfileUpdateForm() context = { 'form': form, } return render(request, 'users/my_profile.html', context) At the moment if I enter a date which is less than 18 years from the current day the date is simply not displayed. What I want instead is for the form to become invalid and show the user an error. How can I achieve this please? -

when do you use quotes in django [closed]
I’m learning django and am a little confused about the use of quotes. It seems that you can use double quotes inside of double quotes instead of the standard double quote single quote paradigm. Also, it seems that some references to urls get quoted and others do not. Can someone point me to the documentation on the use of quotes when coding in django? -
Store data in session for Anonymous User in Django
I need to store token in session for Anonymous User. In one view the data is stored and I can see it in request. But in another request session is empty, but keys are equal. I store data as it in docs: request.session['token'] = token Also session in request in view where data was added: {'_SessionBase__session_key': '6isiuup8xdq7nfr34cmog78t6lkc13p3', 'accessed': True, 'modified': True, 'serializer': <class 'django.core.signing.JSONSerializer'>, 'model': <class 'django.contrib.sessions.models.Session'>, '_session_cache': {'access_token': 'access-sandbox-1d05b2ac-81b4-4126-a57a-7c0ba916252e'}} After that, in another view: {'_SessionBase__session_key': '6isiuup8xdq7nfr34cmog78t6lkc13p3', 'accessed': False, 'modified': False, 'serializer': <class 'django.core.signing.JSONSerializer'>} In settings: INSTALLED_APPS = [ ...

Django Ajax how would i delete the comment using ajax instead of a normal request?
I have code set up so that users can delete comments on an article. However currently, when they delete the comment it will refresh the page and take them back to the top. I'm trying to implement Ajax so that when they delete the comment it'll do it without a page refresh. This is the code I have currently for deleting a comment. index.py <form action="{% url 'add-delete-view' %}" method="POST" class="ui form"> {% csrf_token %} <input type="hidden" name="comment_id" value="{{c.id}}"> <button type="submit" onClick="deleteComment({{c.id}})" id= "{{c.id}}" class="ui primary button c_edit{{c.id}}" name="submit_d_form">delete</button> urls.py path('deleteComment/', views.delete_comment, name='add-delete-view') views.py @login_required def delete_comment(request): comment_obj = Comment.objects.get(id=request.POST.get('comment_id')) comment_obj.delete() return redirect('index') I've attempted to try and implement Ajax but I'm just feeling hopeless in trying to get it work. In index.py I've added function: function deleteComment(comment_id) { var action = confirm("Are you sure you want to delete this comment?"); var comment = $(this) if (action != false) { $.ajax({ method: 'DELETE', url: '{% url "add-delete-view" %}', success: function (data, textStatus, jqXHR) { comment.remove(); }, }); } } But I'm just not sure where to go next or if this will even work.

Django reload current page using a button
Is there actually any way to simply reload the page in Django I'm currently viewing, preferably at the template with a button?
