Django: How to use more than 2 Class Based Generic Views in one template
I was trying to create a web app in which a user can see other posts while updating a post. So, for that, I want to use both ListView And UpdateView together in the same template. My Views.py: from django.shortcuts import render from .models import Entry from django.views.generic import ListView from django.views.generic.edit import UpdateView from django.contrib.auth.models import User from django.contrib.auth.mixins import LoginRequiredMixin, UserPassesTestMixin class index(LoginRequiredMixin, ListView): template_name = 'diary/index.html' context_object_name = 'entries' def get_queryset(self): # def get_queryset(self, request): return Entry.objects.filter(author=self.request.user) class EntryUpdate(LoginRequiredMixin, UserPassesTestMixin, UpdateView): model = Entry fields = ['title', 'content'] template_name = 'diary/update.html' def form_valid(self, form): form.instance.author = self.request.user return super().form_valid(form) def test_func(self): post = self.get_object() if self.request.user == post.author: return True else: return False I don't know if I should create another view, or that there is an inbuilt functionality for this, so, it would be really helpful if you guys can help me out. Any Help Would Be Appreciated! -
Making HTTP GET request that target a collection of instances in DjangoRESTFUL

How to fix 'User has no attribute usergroup' eventhough it's added?
I have to develop a register form, I'm using crispy forms for this. (It was not my idea...), So I wrote a RegisterForm class (see code), and added some nice fields to work with, they all do work, unless usergroup = forms.ChoiceField(choices=GROUPS). Django shows me an Attribute error: User' object has no attribute 'usergroup'. Eventhough I can call all the other things such as fullname and email. I've already tried setting it to CharField and enter it manually but this gives me an error too. GROUPS = ( ('None', 'Choose...'), ('xyit', 'xy IT'), ('xyhr', 'xy HR'), ('xysales', 'xy Sales'), ('cn', 'admin'), ) class RegisterForm(UserCreationForm): fullname = forms.CharField() usergroup = forms.ChoiceField(choices=GROUPS) email = forms.EmailField() class Meta: model = User fields = ["fullname","usergroup", "username", "email", "password1", "password2"] And this is where I want to call it: def contacts(request): username = None if request.user.is_authenticated: username = request.user.username fullname = request.user.fullname email = request.user.email usergroup = request.user.usergroup print(email, fullname, usergroup) numberDevices = len(DeviceInformation.objects.all()) numberDevicesUser = len(request.user.deviceinformation.all()) return render(request, contact_req, {'username':username, "numberDevices": numberDevices, "numberDevicesUser": numberDevicesUser,}) else: return render(request, unauthorized_req, status=401) {% block register %} <form method="POST" class="form-group"> {% csrf_token %} {{ form|crispy}} <button type="submit" class="btn btn-dark">Register</button> </form> {% endblock %} Django==2.2.4 Python==3.6.8 AttributeError by Django … -

How to download content from my Django webpage?
I have a table on one of my Django webpage. I want to give the user the ability to download the content of the table in xl format. What would be an efficient and good way of doing this? I was thinking of creating an xlsx file using the xldr library. Writing the data on the file. making the file available for download and then deleting the file at the end, so that my drive stays clean. but it doesn't feel like a very efficient way. I'm new in web development, so open to all kind of ideas. Thanks -
Many-To-Many reverse field lookup with ids in Django
I try to figure out how to produce the correct queryset to retrieve url and value fields (Attr_1 and Attr_2 model) from querying the Object1 models 'reverse set' Many-to-Many Relation. Here is my Example: models.py: class Text(models.Model): string = models.TextField() #Entity class Element(models.Model): pageline = models.IntegerField() class Object1(Element): text = models.ManyToManyField(Text) class Object2(Element): another_var = models.ManyToManyField(Text) yet_another = models.CharField(max_length=1) #Entity class Attribute(models.Model): belongsTo = models.ManyToManyField(Element) class Attr_1(Attribute): url = models.URLField() class Attr_2(Attribute): value = models.CharField(max_length=255) date = models.URLField() If I use: >> models.Object1.objects.get(pk=1).attribute_set.all() <QuerySet [<Attribute: Attribute object (1)>, <Attribute: Attribute object (2)>]> >> models.Object1.objects.get(pk=1).attribute_set.values() <QuerySet [{'id': 1}, {'id': 2}]> I guess now I have to query Attr_1 for pk=1 and Attr_2 for pk=2? Does the Attribute model has a relation to know if id=1 is in Attr_1 or Attr_2 model? Any help is appreciated. Thank you! -

Django: transfering two primary keys to new detail view
I'm trying to create a detail view where I use employee and subject name to show the evaluations created in the specific subject. I currently have this detail where, where I'm looping through the subject names and displaying all the evaluations for the subject for the employee. The view is using employee as the primary key. So when I press on the subject name from the loop below, I wish to go to a new view where I show the evaluations for the subject by the specific employee. Employee template {% for subject in subject_list %} {{ subject.subjectname }} {% for evaluation in subject.evaluation_set.all %} {{ evaluation.instructor }} {{ evaluation.ma }} {% endfor %} {% endfor %} I can't figure out what the best way to do this is. I believe using the employee primary key for the new view is correct, but how do I "transfer" the subject id from the loop to the next view? Alternatively I can use the subject id for the view but then I don't understand how to "transfer" the employee over. Employee view with subjects class EmployeeEvalDetailView(DetailView): template_name = 'evalsys/evalueringer/se_alle_evalueringer.html' model = Employee def get_context_data(self, **kwargs): context = super(EmployeeEvalDetailView, self).get_context_data(**kwargs) context['fagene'] = Subject.objects.all().prefetch_related(Prefetch('evaluation_set', … -
Responsive images wagtail django
My image is supposed to sit in a div which is 50% screen width (max width 800px for image in div) until 640px screen width where the div is 100%. I want the image to change height and width with the div. I want the whole image to always be shown basically. At the minute neither is changing and its messing up the responsiveness of the whole page. <tr class="fadeInBlock"> <td><!--div for image of architecture--> <div class="homeInfo5"> {{ page.architecturalText|richtext }} </div> </td> <td> <div class="homeIm4 responsive"> {% for item in page.gallery_images.all %} {% image item.image width-500%} <p>{{ item.caption }}</p> {% endfor %} </div> </td> </tr> .homeIm4 { height: auto; float: left; } .responsive { width: 100%; max-width: 250px; height: auto; } @media all and (max-width:640px) { table, thead, tbody, th, td, tr { display: block; } } In the image tag I have tried min max width original and fill. Nothing I've tried has worked. Without the image the responsiveness of the page is fine with just the text field. -

Django-filter 2 use @property to filter?

Is it even possible for me to use django-filter with a @property? Thanks for any answer! -

Bad pratice in ajax request appending html in a django template
In my page I have all the objects of the db displayed, with template tags I forloop the queryset to make every object displayed in a card. I want to filter these objects by category (which is a parameter) without refreshing the page so I made an ajax request which gets a JSON with the filtered objects and diplays them. The ajax function works fine but involves some bad practice as you can see in the code below. # my view class HomeView(ListView): model = Item paginate_by = 4 template_name = "home-page.html" //relevant part of my template <div class="row wow fadeIn" id="hardwarelist"> {% for item in object_list %} <div class="col-lg-3 col-md-6 mb-4"> <div class="card"> <div class="view overlay"> <img src="{{item.image}}" class="card-img-top" alt="" height="330" width="330"> <a href="{{ item.get_absolute_url }}"> <div class="mask rgba-white-slight"></div> </a> </div> <div class="card-body text-center"> <a href="" class="grey-text"> <h5>{{ item.get_category_display }}</h5> </a> <h5> <strong> <a href="{{ item.get_absolute_url }}" class="dark-grey- text">{{item.title}}<br/> <span class="badge badge-pill {{ item.get_label_display }}-color"> {{item.label}} </span> </a> </strong> </h5> // ajax function // bad pratice here, I append the card html tag by tag changing template tags // like {{item.title}} with js variables like objects.title, // basically I append all the html diplayed above and it's clearly bad … -
Patching default value of the field
I have a model with uuid field with default value as a function. from uuid import uuid4 def _new_uid(): return uuid4() class A(models.Model): name = models.CharField() uid = models.UUIDField(unique=True, default=_new_uid, editable=False) In test I want to patch _new_uid method return 11111111-1111-1111-1111-111111111111. @patch('module.foo._new_uid', Mock(return_value='11111111-1111-1111-1111-111111111111')) def test_create_A(): response = api_client.post('/api/a-list/', { 'name': 'test', }) assert response.json() == { '_uid': '11111111-1111-1111-1111-111111111111', 'name': 'test' } But it still returns some random uuid. I guess it's happening because model initialization is over before test start running. I can avoid it by changing default option to: uid = models.UUIDField(unique=True, default=lambda: _new_uid(), editable=False) Can it be done without changing default to lambda call? -
Django - Associating models with one another
As a part of a task, I created an "apartment listings" website. I managed to get that done, but now I need to make a "reservation system" for it. The basic idea is that a logged in user can select an apartment from the listed apartments, pick a "start_date" and an "end_date" (if the apartment already isn't booked ) and book the apartment. Im a total Django newbie, and need some pointers in order to start somewhere with this task. I have an Apartment model which contains all of the Apartments info that I use to print everything out with the template. I'm using the provided django user models to register / log-in. I’m using Django 2.1.8 I have created this view and model to make my reservations : view: def apartment_view(request, apartment_id): apartment = get_object_or_404(Apartment, pk=apartment_id) context = {'apartment': apartment, } context_instance = RequestContext(request) form = ReservationForm() if request.method == 'GET': form = ReservationForm() elif request.method == 'POST': form = ReservationForm(request.POST) if form.is_valid: form.save() # to go back to check that the info has changed return HttpResponseRedirect('/booking/') args = {} args['form'] = form return render(request, 'booking/index.html', args) models: class Apartment(models.Model): title = models.CharField(max_length=200) address = models.CharField(max_length=200) city = models.CharField(max_length=100) … -

Django - Initial form value from templates
