PYTHON: I'm trying to read different values from XML files and send to Django Html template
I have already read the xml values but i think that the way which i'm using to store the data is wrong. I'need to store a list, or a dict or list of dict some values and then send to the HTML Template and render an HTML Table with all the values: this should be the result and the following code is how i'm actual reading the values from XML for files in file_in_path: fileP = os.path.join(path,files) tree = ET.parse(fileP) roots = tree.getroot() for x in roots.findall('DatiGeneraliDocumento'): //node of xml file that i need to read tipdoc = x.find('TipoDocumento').text //all the data numdoc = x.find('Numero').text datadoc = x.find('Data').text mydict = {"tipdoc":item,"numdoc":numdoc,"datadoc":datadoc} //then i'm trying to save in dict liste.append(mydict)//and append all to a list context = {"data":liste} return(response, "page.html", context) when i'm in my html page and trying to print the result with django format language "{{ data }}" he print out one value and not all of of them, but if in python file i print out my list he print out all list. which is the best way to store all the values in all the xml files and then print out in a html table? -

Django 2.2 - how to express a constraint between two fields
I have a couple of models that look like this: class AlarmStatus(Enum): UNDEFINED = "Undefined" PENDING = "Pending" CUSTOMER_PENDING = "Customer Pending" @classmethod def choices(cls): return tuple((i.name, i.value) for i in cls) class Alarm(models.Model): managed = models.BooleanField(default=False, blank=False, verbose_name="Managed ?") status = models.CharField( max_length=20, default=AlarmStatus.UNDEFINED.name, choices=AlarmStatus.choices() ) class Meta: constraints = [ models.CheckConstraint( check=Q(managed=False) & Q(status=AlarmStatus.UNDEFINED.name), name="if_managed_is_False_status_must_be_UNDEFINED") ] I would like to enforce at the db level the following invariant: if an alarm managed field is False, then its status field MUST be "UNDEFINED". I.e. I want to declare illegal the following state/combination: managed == False AND status == (PENDING | CUSTOMER_PENDING) How can I enforce this? I tried with the above constraint but it is clearly wrong, because it is enforcing that every row managed field must be False AND every row status must be UNDEFINED. Thanks -

Django Python form , dynamic value

Django query related objects by there content_type
I have a Hit table at my Django project that stores view-counts for multiple object_types e.g. Post, Products & Profile models ... What I do not understand is how I can pull out object out of my Hit table that belong to a specific content_type or in other words, how to build the query correctly. Take the following query(s) as an example where I want to get all objects by there content_type out of my Hit Table: def recently_viewed_proposals(): hit = Hit.objects.all() queryset_p = Hit.objects.filter(pk__in=hit.filter(content_type=12).values_list('id', flat=True)) queryset_psm = Hit.objects.filter(pk__in=hit.filter(content_type=15).values_list('id', flat=True)) queryset_pso = Hit.objects.filter(pk__in=hit.filter(content_type=20).values_list('id', flat=True)) hit_elements = chain( queryset_p.random(len(queryset_p)), queryset_psm.random(len(queryset_psm)), queryset_pso.random(len(queryset_pso)) ) post_elements_list = list(hit_elements) print(post_elements_list) n_proposals = min(len(post_elements_list), config.MAX_RECENTLY_VIEWED_PROPOSALS) recently_viewed_proposals = random.sample(post_elements_list, n_proposals) return recently_viewed_proposals 12 = content_type id of Post model This is how my Hit table look like: class Hit(models.Model): objects = RandomManager() content_type = models.ForeignKey(ContentType, limit_choices_to=hit_models, on_delete=models.CASCADE) object_id = models.CharField(max_length=36) content_object = GenericForeignKey('content_type', 'object_id') viewer = models.ForeignKey(User, verbose_name="Viewer", on_delete=models.CASCADE) date_added = models.DateTimeField(auto_now=True) But I just get back the pk of the Hit model and not the pk's of the Post objects I stored at the Hit table. How can I access the pk's of my Post objects? -
pass attrs to BoundField.as_widget() django
I want to pass html attributes with BoundField.as_widget() by passing them to attrs in the method. Django doc says BoundField.as_widget(widget=None, attrs=None, only_initial=False)¶ Renders the field by rendering the passed widget, adding any HTML attributes passed as attrs. If no widget is specified, then the field’s default widget will be used. So I tried passing attributes like this: BoundField.as_widget(attrs={'class': 'container'}), which didn't work. forms.py class HiddenForm(forms.Form): testfield = forms.CharField(max_length=100, widget=forms.HiddenInput(attrs={'class': 'container'})) class BlahForm(forms.ModelForm): class Meta: model = Blah views.py.

How can a delete request be redirected to a specific url in django rest framework?
Currently, I have made a "Like" model and have implemented "Like" and "Uike" by post and delete requests, respectively. So after implementing Like, I want to implement Unlike, and I know that in order to implement it, I have to select the pk of that Like object, map it to url, and then send a delete request to that url. However, this method requires both url called "/post_id/like/like_id" and "/post_id/like_id", which I do not do, but try to redirect from views to "/post_id/like/like_id" when a delete request is sent to url called "/post_id/like/like". How can I make logic to proceed with the code as I think? Here's my code. views.py class CreateReadLikeView (ModelViewSet) : serializer_class = LikeSerializer permission_classes = [IsAuthenticated] queryset = Like.objects.all() is_saved = False def get_queryset (self) : return super().get_queryset().filter(post=self.kwargs.get('post_id')) def perform_create (self, serializer) : postId = self.kwargs.get('post_id') post = Post.objects.get(pk=postId) try : like = self.queryset.get(post=post, liked_people=self.request.user) except Like.DoesNotExist : serializer.save(liked_people=self.request.user, post=post) self.is_saved = True def create (self, request, *args, **kwargs) : super().create(request, *args, **kwargs) if self.is_saved is True : self.is_saved = False return Response({'success': '해당 게시물을 좋아요 했습니다.'}, status=200) return Response({'message': ['이미 해당 게시물을 좋아요 하였습니다.']}, status=400) def list (self, request, *args, **kwargs) : postId = self.kwargs.get('post_id') … -
Django Search Page with Query Pagination
Hello i have implemented a simple search form and search view to show search result. Now i want to paginate them. But there is a problem with the page in the url. My search url looks like ../search?q=Bla Now if i try to add pagination like: ../search?q=Bla?page=2 (at least thats how i understand it would work) it takes the whole string after q= to my database filter. I took a look at how stackoverflow handles searching and pagination and found out using '&' here is the view code: def search(request): # get query search parameters page = request.GET.get('page', 1) query = request.GET.get('q', '') # query none or empty if query is None or query == '': return redirect('home') # query valid else: # icontains make sure to ignore character sensitivity post_list = Post.objects.filter(title__icontains=query) paginator = Paginator(post_list, 5) try: posts_l = paginator.page(page) except PageNotAnInteger: posts_l = paginator.page(1) except EmptyPage: posts_l = paginator.page(paginator.num_pages) return render(request, 'search.html', {'post_list': posts_l, 'query': query}) and here the HTML Snippet: {% if post_list.paginator.num_pages > 1 %} <div class="pagination"> <span class="step-links mb-5 mx-auto"> {% if post_list.has_previous %} <a class="mr-3" href="?page={{ post_list.previous_page_number }}&q={{ query }}">zurück</a> {% endif %} <span>Seite {{ post_list.number }} von {{ post_list.paginator.num_pages }}</span> {% if post_list.has_next … -
Customize request made by Django drf-yasg
I want to change the request drf-yasg generates and executes in the 'Try it out' editor. My API endpoint accepts a request with query params like query_params = { data: [1, 2], field: "string_value" } <url>?data[]=1&data[]=2&field=string_value but when I have annotated my endpoint with @swagger_auto_schema( method="GET", manual_parameters=[ Parameter("data", IN_QUERY, type=TYPE_ARRAY, items=Items(type=TYPE_STRING)), Parameter("field", IN_QUERY, type=TYPE_STRING), ], ) the 'Try it Out' editor generates the request as <url>?data=1,2&field=string_value Is there any way I can cganhe the way drf-yasg generates the request for a specific type? -
