django-filter AssertionError: Cannot filter a query once a slice has been taken
I'm using Django-filter ,I want to slice the rows ,just want the first 75 row: def hist_view_render(request): all_obj = RunStats.objects.all().order_by('-create_dttm')[:75] hist_filter = RunStatsFilter(request.GET, queryset=all_obj) paginator= Paginator(hist_filter.qs, 15) page = request.GET.get('page') try: response = paginator.page(page) except PageNotAnInteger: response = paginator.page(1) except EmptyPage: response = paginator.page(paginator.num_pages) context = {'response': response,'filter': hist_filter} return render(request, 'runstat_hist.html',context) I have tried put the [:75] in different places ,but I always receive the error: Cannot filter a query once a slice has been taken The only way that works is slice it in the template ,but I want to find a way to slice it in the views.py. Any friend can help ? -
How can I paginate the attributes from a model?
I have a single for each series, but I want to paginate inside this page. I want to paginate the episodes because some series have more than 100 episodes and it is too much for a single page. class SerieDetailedView(DetailView): template_name = "tailwind/series_detail.html" model = Serie slug_url_kwarg = "serie_name" slug_field = "name" context_object_name = "project" def get_object(self, queryset=None): return Serie.objects.get(name=self.kwargs["serie_name"]) In this case, I have this as my model: class Serie(models.Model): name = models.CharField(max_length=150, unique=True) finished = models.BooleanField(default=False) episodes = ArrayField(base_field=models.CharField(max_length=100), default=list) published_at = models.DateTimeField(auto_now_add=True) I’m just getting how to paginate all the series, but it’s different, I want to paginate a thing that is inside the series. I’ve tried to do it, but it has not worked because is a single page: class SerieDetailedView(DetailView): template_name = "tailwind/series_detail.html" model = Serie slug_url_kwarg = "serie_name" slug_field = "name" context_object_name = "project" paginate_by = 10 def get_object(self, queryset=None): return Serie.objects.get(name=self.kwargs["serie_name"]).episodes.order_by('-published_at') -

How I can create fields into a model in dependence of another one?
I'm learning Django and I'm working in a test project.

In the other I want to select the first which was already created and assign him how many references it has and create a field for each reference. -

APIView PUT request being handled as a GET request
I'm building an APIView to handle a PUT request for a model with choicefields as input. Originally, I created a GET and PUT definition for my APIView class, however when my build is deployed, my PUT request is being received as a GET request! On my dev deployment, the request is received as a PUT request every time. When I move it to a production deployment however, the only times I can get the request to properly send a PUT request is by using Postman. When I try any other way the request is received as a GET request. Removing the definition of GET from my APIView does not help, it simply returns a 405 method not allowed. I've looked around and don't seem to see any other people with this issue. What could cause a request to be misinterpreted like this? Where would be a good place to start looking? Can I force the use of PUT at this endpoint? In the meantime I'm going to try moving from APIView to one of the specific generics mixins to see if this resolves my issue. -
How to allow boolean True on just one model in table in Django?
I've got a model where I would like there to be able to have one set as the 'app default'. In this model I added a field named is_app_default in order to help accommodate this. class TreeLevel(models.Model): id = models.BigAutoField(primary_key=True) short_description = models.CharField(max_length=200) long_description = models.TextField() is_app_default = models.BooleanField(default=False) class Meta: verbose_name = "Tree Level" verbose_name_plural = "Tree Levels" class Layer(models.Model): id = models.BigAutoField(primary_key=True) tree_levels = models.ManyToManyField(TreeLevel) description = models.TextField() class Meta: verbose_name = "Layer" verbose_name_plural = "Layers" The Layer model links to TreeLevel with an m2m. Ultimately I would like the is_app_default TreeLevel automatically added to every Layer m2m relationship - which is why there can only be one TreeLevel with is_app_default set as True. My potential solution(s): Users with admin may be creating new TreeLevel objects - so I need to make sure they aren't setting that Boolean in any new models. I think I can override the save() method on TreeLevel to check the DB to see if another with that boolean as True exists - if so? Don't save the 'new' one and return an error. But I think this hits the database - causing unnecessary queries potentially? Then additionally, I would also need to override … -

How to filter queryset from inside the serializer?
I want to always apply a filter to a serializer (filter the queryset). lets say I have: class Company(models.Model): name = models.CharField(max_length=90, unique=True) city = models.CharField(max_length=90,) active = models.BooleanField(default=True) class CompanySerializer(serializers.ModelSerializer): class Meta: model=Company fields=['id', 'name', 'city'] so when I call the serializer for a list filtered by city (or any other fields added in my real code) as shown below it returns Companies from that city and only "active=True" query_set = Company.objects.filter(city=request.POST(city) ) srl = serializers.CompanySerializer(query_set, many=True) return Response(srl.data) because I may want to call the serializer from other parts of the code. and I want to keep the records for reference but never show to any client. I have tryed to modify the queryset from from init but it does not work. I actually print() the modified queryset to make sure it was filtered and it prints the filtered queryset, I do: def __init__(self, instance=None, data=empty, **kwargs): instance.filter(active=False) self.instance = instance print(self.instace) #this prints the filtered queryset OK but it sends the response without the "active=False" filter. -

Python: Basic OCR / Image to Text library
I have a very simple use case for OCR. .PNG Image then extract the text from the image. Then print to console. I'm after a lite weight library. I am trying to avoid any system level dependency's. Pytesseract is great, but deployment is a bit annoying for such a simple use case. I have tried quite a few of them. They seem to be designed for more complex use cases. Note: White text is not necessarily suitable for OCR. I will change the image format to suit the OCR Library. -

Say I have this in a template: {% example %}import * as fancy from "{% static 'jslib/fancy.min.js' %}";{% endexample %} I wish to output it as (I will add some divs and styling, but this is distilling the problem into it's simplest form): import * as fancy from "{% static 'jslib/fancy.min.js' %}"; import * as fancy from "/static/jslib/fancy.min.js"; I looked at the django {% verbatum %} tag and tried to copy the logic: # django.template.defaulttags.py @register.tag def verbatim(parser, token): nodelist = parser.parse(('endverbatim',)) parser.delete_first_token() return VerbatimNode(nodelist.render(Context())) nodelist.render(Context()) prints out text nodes for the django verbatim tag, but if I copy the code my example tag prints out say StaticNodes and other types of nodes. The reason why is I think the django parser has some special checks to see if it is a verbatim node and handles if differently, as shown in the code below: # django.template.base.py -> def create_token if self.verbatim: # Then a verbatim block is being processed. if content != self.verbatim: return Token(TokenType.TEXT, token_string, position, lineno) … -
Django does not recognize my {% endblock %} tag in the html file
I get this error while trying to run my Django project: "Invalid block tag on line 7: 'endblock'. Did you forget to register or load this tag?" I am trying to make a base-template (base.html) and use it on my html file (index.html). The name of my Django project is "mysite", the name of the app in my Django project is "myapp" It looks like Django does not recognize my {% endblock %} tag, but i don't know why. This is the base-template file (base.html): {% load static %} <html lang="en"> <head> <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap@4.0.0/dist/css/bootstrap.min.css" integrity="sha384-Gn5384xqQ1aoWXA+058RXPxPg6fy4IWvTNh0E263XmFcJlSAwiGgFAW/dAiS6JXm" crossorigin="anonymous"> <link rel="stylesheet", href="{% static 'myapp/style.css' %}"> <title>Document</title> </head> <body> <nav class="navbar navbar-expand-lg navbar-dark bg-dark"> <a class="navbar-brand" href="#">Navbar</a> <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation"> <span class="navbar-toggler-icon"></span> </button> <div class="collapse navbar-collapse" id="navbarSupportedContent"> <ul class="navbar-nav mr-auto"> <li class="nav-item active"> <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a> </li> <li class="nav-item"> <a class="nav-link" href="#">Link</a> </li> <li class="nav-item dropdown"> <a class="nav-link dropdown-toggle" href="#" id="navbarDropdown" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false"> Dropdown </a> <div class="dropdown-menu" aria-labelledby="navbarDropdown"> <a class="dropdown-item" href="#">Action</a> <a class="dropdown-item" href="#">Another action</a> <div class="dropdown-divider"></div> <a class="dropdown-item" href="#">Something else here</a> </div> </li> <li class="nav-item"> <a class="nav-link disabled" href="#">Disabled</a> </li> </ul> <form class="form-inline my-2 my-lg-0"> <input class="form-control mr-sm-2" type="search" placeholder="Search" aria-label="Search"> <button … -
