iframe on load function only triggers on certain loads, not all internal clicks
$('iframe').on('load', function () { ... } I have this piece of code, but the iframe can navigate away from it's core page, yet I can't seem to trigger a function from when the navigation has loaded. I want to be able to trigger an ajax call in django for every click's load to update the data over the top of the iframe. -

request.user not working properly and can't be assigned to hidden model field
I am making a little image sharing website which is a lot like a blog. When I try to assign form.author = request.user, it doesn't work and the form on my website returns 'this field is required' error. I tried even other similiar projects on github to check if the error is in the project but it seems not because I get errors there too. But the interesting part is when I try to print the request.user object it prints the object without a problem but when I try to assign it for some reason it returns null. Then I tried twisting the code in every possible scenario but I couldn't debug it. This is my models.py class Meme(models.Model): title = models.CharField(max_length=100) author = models.ForeignKey(User, on_delete=models.CASCADE) meme = models.ImageField(upload_to='memes/') This is my view def upload(request): form = MemeUploadForm(request.POST or None) if request.method == 'POST': print(request.user) if form.is_valid(): obj = form.save(commit=False) obj.author = request.user obj.save() redirect('blog-index') return render(request, 'blog/upload.html', {'form': form}) This is my form class MemeUploadForm(ModelForm): class Meta: model = Meme fields = ['title', 'meme'] When I try to get the view to return the request.user it gives me Attribue error: User' object has no attribute 'get' but when I … -

javascript function should switch between 2 images in a django template but doesn't
I have a js function that should switch between 2 images when a button is clicked. This function worked fine switching images in an html page but when I used it inside a django project fails to change images in the template. The initial situation was like this: the first image is displayed when the page is loaded, when the button is clicked it tries to change to the second images but fails to locate the source and gives a 404 error, a second click also fails to load the first image back; so I fixed the path to the second image, now pressing the button once correctly load the second image but when clicked again fails to load the first image, pressing the button a third time correctly loads the second image tho, a step foward. So I fixed the path to the first image (both images have the same path) and now clicking the button does nothing, the first images stands still. the path is this: ProjectName/AppName/static/AppName/dog1.jpg {%load static%} <img id="avatar" src="{% static 'AppName/dog1.jpg' %}" class="avatar"> <button id="Btn">Click me to change dogs<button> const dogs = [ "dog1.jpg", "/static/AppName/dog2.jpg" ]; const avatar = document.getElementById('avatar'); /*const dogs this way makes … -

Related resources on a nested URL in Django Rest Framework
I have two models, Foo and Bar. Bar has a foreign key to Foo. I have a ModelViewSet for Foo and I want the route /api/foos/<pk>/bars/ to return all the bars related to the given foo. I know this can be done using actions. For example class FooViewSet(viewsets.ModelViewSet): serializer_class = FooSerializer queryset = Foo.objects.all() @action(detail=True, methods=['GET']) def bars(self, request, pk): queryset = Bar.objects.filter(foo=pk) serializer = BarSerializer(queryset, many=True) return Response(serializer.data) @bars.mapping.post def create_bar(self, request, pk): request.data['foo'] = pk serializer = BarSerializer(request.data) serializer.is_valid(raise_exception=True) serializer.save() return Response(serializer.data, status=status.HTTP_201_CREATED) However, this feels like a lot of unnecessary boilerplate code. Is this possible to do in viewsets in a more convenient way? If not, what is the normal DRF way of doing it? A solution with a different URL is also acceptable for me as long as it minimizes boilerplate code. -
Django - how to add prefix to Mixin attributes (possible?)
There is too much relations and chains of actions in my project so I decided to eliminate some relations and use Mixins instead to keep things DRY. For example: class AddressMixin(BaseModel): address_zip = models.CharField(max_length=6, null=True, blank=True, verbose_name='PSČ') address_lat = models.DecimalField(max_digits=24, decimal_places=20, null=True, blank=True) address_lng = models.DecimalField(max_digits=24, decimal_places=20, null=True, blank=True) ... class Meta: abstract = True def some_method... There are many models using Address where I use this as a Mixin but sometimes, I need two or three types of addresses in one model. class Client(..): home_address = OneToOneField('addresses.OldAddressModel',...) work_address = OneToOneField('addresses.OldAddressModel',...) Here I can't just use AddressMixin like Client(AddressMixin,Model) since I need two different addresses. I would like to use AddressMixin two times with different prefixes, so in final model, there would be home_address_city and work_address_city. Is it possible to do that? I was thinking about some MixinFactory which takes Mixin and prefix and then it prefix all attributes (and maybe methods too but I can live without prefixed methods...). -
Django static files not loading with no error signs

Django inlinefomrset delete
Here is a mystery. I cannot get the inlineformset deletion to work property. I have followed the docs to delete forms in my formset processing: # In my forms.py: def clean(self, *args, **kwargs): ''' Custom clean method to handle deletion ''' super(BaseDevelopmentTypeInlineFormSet, self).clean(*args, **kwargs) if any(self.errors): return # Everything beyond this point is clean cd = self.cleaned_data for form in self.forms: the_can_delete = self.can_delete # can_delete returns True the_should_delete = self._should_delete_form(form) # _should_delete returns False! form_fields = [ field for field in form.fields ] if self.can_delete and self._should_delete_form(form): continue form_cd = form.cleaned_data And, here are the relevant sections of the views.py: if development_type_formset.is_valid(): development_types_cd = development_type_formset.cleaned_data forms_marked_for_deletion = development_type_formset.deleted_forms assert False # forms_marked_for_deletion correctly returns the forms that have been marked for deletion the_kwargs = {'development_project': active_development_project } development_type_formset.save(**the_kwargs) assert False # the_development_types = [] is returned return HttpResponseRedirect(reverse('development:add_details', args = (the_id,))) After submitting, the redirection to another url happens successfully. But, when I go back, I still see the forms that should have been deleted. Originally, I thought the problem is with _should_delete, so I commented the part of the code calling _should_delete out.

How to iterate across HTML elements a specific number of times?
I'm having trouble coming up with working logic for the use case of repeating a set of HTML elements across columns. Simplified HTML as an example: {% for day in days %} <div class="container"> <div class="row"> {%for room in day.rooms%} <div class="col-sm-3"> <section class="box"> <h4>{{room.name}}</h4> {%for session in day.sessions%} {%if session.leftpos == room.leftpos %} {%if session.id%} <a href="session/{{session.id}}-{{session.title|slugify}}/">{{session.timeslot}}<br/><b>{{session.title}}</b><br/></a> {%else%} {{session.timeslot}} - <b>{{session.title}}</b> {%endif%} {%for speaker in session.speakers %}{%if loop.first%}{%else%}, {%endif%}<i><a href="speaker/{{speaker.id}}-{{speaker.name|slugify}}/">{{speaker.name}}</a></i>{%endfor%} {%endif%} {%endfor%} </section> </div> {%endfor%} </div> </div> {%endfor%} As this currently works, it looks for rooms depending on the sortkey, and lines up the talks corresponding with what rooms by going off that sortkey (if session.leftpos == room.leftpos). I have another variable (session.cross_schedule) which applies to talks which span across all 3 rooms, meaning that's the featured session. What I need to determine is how best to repeat the session information (everything within for session in day.sessions) across for room in day.rooms, but only if it's session.cross_schedule. Ideally, these cross-scheduled talks would appear at the proper time in the schedule rather than being separated from the rest. Any ideas or guidance would be much appreciated! -
Implement google autocomplete for address fields whilst using django models for forms
I have used django models to create the forms then loaded in the fields using crispy forms. The current implementation uses a standard text field to take in the address straight from the models. I would like to add the auto complete feature so that no incorrect addresses are entered in. I am unable to access the raw code as crispy forms loads everything in straight from the models so I cannot attach the code required for the autocomplete feature. I have tried to add a block in to manually add in the address however, this can only be added at the top or the bottom of the form. This is a problem as I need to add the address after the user entering the title of the listing. forms.py class ListingDevelopmentForm(forms.Form): title = forms.CharField() slug = forms.SlugField() description = forms.CharField(widget=forms.Textarea) first_line_address = forms.CharField() second_line_address = forms.CharField() postcode = forms.CharField() number_of_properties= forms.IntegerField() site_plan = forms.IntegerField() price = forms.DecimalField() rent = forms.DecimalField() ownership = forms.CharField() tenure = forms.CharField() from.html <form method="post" action='.' enctype='multipart/form-data'> {% csrf_token %} {{ form|crispy }} {% block main1 %} <!-- this is where I have added the block which allows me to manually add in the code … -
