Django Rest Framework Django Filters ModelMultipleChoiceFilter doesn't work with icontains
I'm trying to filter Django permission groups by the permissions within the group which has a ManyToMany relationship. I'm using django == 3.2.5, django_filter == 2.4.0 and django_rest_framework==3.12.4. Currently the filter only works if I use "exact" as my field lookup but when I use "icontains" it throws this error; { "permissions__icontains": [ "“can” is not a valid value." ], I can't see what I'm doing differently versus from docs and this stack overflow post. https://django-filter.readthedocs.io/en/stable/ref/filters.html?highlight=ModelMultipleChoiceFilter#modelmultiplechoicefilter How to use ModelMultipleChoiceFilter? Is there a way I can get filter results when it is not an exact match?? cheers in advance! request url http://127.0.0.1:8000/permission_groups/?permissions__icontains=can filter class PermissionsGroupFilterSet(FilterSet): name = AllValuesMultipleFilter(field_name="name") permissions = ModelMultipleChoiceFilter( queryset=Permission.objects.all(), field_name="permissions__name", to_field_name="name" ) class Meta: model = Group fields = { "name": ["icontains", "in"], "permissions": ["exact", "icontains"], } models.py (standard group/permission models) class Group(models.Model): name = models.CharField(_('name'), max_length=150, unique=True) permissions = models.ManyToManyField( Permission, verbose_name=_('permissions'), blank=True, ) objects = GroupManager() class Meta: verbose_name = _('group') verbose_name_plural = _('groups') def __str__(self): return self.name def natural_key(self): return (self.name,) class Permission(models.Model): name = models.CharField(_('name'), max_length=255) content_type = models.ForeignKey( ContentType, models.CASCADE, verbose_name=_('content type'), ) codename = models.CharField(_('codename'), max_length=100) objects = PermissionManager() class Meta: verbose_name = _('permission') verbose_name_plural = _('permissions') unique_together = [['content_type', 'codename']] … -
Saving an object with formset element AND making a copy with new related elements
I'm trying to do some kind of a mixte between a Create and an Update on an object that has foreign keys (managed as inline formset). Updating the parent object in a form (as well as its related formset forms) works fine. I can also save a copy of that parent object as a new instance in the DB, that works fine. However I can't seem to figure out how to also make copy of the formset as new independant objects. Basically, once all is said & done, I want: Foo (pk=1) bar_1 bar_2 ... bar_n FooCopy (pk=2) bar_1_copy ... bar_n_copy I currently can modify Foo, create FooCopy, as well as modify bar_1 to bar_n... but cannot create bar_1_copy etc. For instance: class SoumissionUpdateView(LoginRequiredMixin, SideBarMixin, UpdateView): def form_valid(self, form, formset): # that saves any modification to the initial object, as well as the elements in the formset self.object = form.save() formset.instance = self.object formset.save() # this saves the parent object as a new instance. However no new formset objects are created in the db. self.object.pk = None self.object.save() formset.instance = self.object formset.save() # since those should be 2 different sets of instance in db return HttpResponseRedirect(self.get_success_url()) My understanding was since … -
Filtering field in a django form
I am building a website with django. This website is user based and each user has a profile model. Right now, I am working on building a system where each user can input their job experience. I want it so that you can input a category, and then fill out points for each category. (For example, if you wrote for the New York Times, the category would be "New York Times" and then right under it would be the articles you wrote in bullet points). I can create a category. I can create a work and then assign the work to a category. The issue I am having is that a user can choose a category from a different user in the work form. All I want to do is make it so that the field "category" is filtered so that users can only select categories that they made. I have tried a couple of things but I am not sure where is the best place to filter this field. models.py from django.db import models from django.contrib.auth.models import User class Category(models.Model): user = models.ForeignKey(User, on_delete=models.DO_NOTHING, null=True, blank=True, related_name='cat') name = models.CharField(max_length=100) date = models.DateTimeField(auto_now=False, auto_now_add=False, null=True, blank=True) def __str__(self): return … -
AttributeError: 'InMemoryUploadedFile' object has no attribute 'decode'
I am building a django application where I upload a folder containing a lot of CSV files. I retrieve the folder like this in HTML and it works fine: <div class="upload_csv"> <h2>Upload</h2> <form method="post" enctype="multipart/form-data"> {% csrf_token %} {{ form.as_p }} <input type="file" name="folder" multiple="true" webkitdirectory="true" directory="true"/> <button type="submit">Upload</button> </div> Now, the problem is that I need to use "utf-8" encoding before moving on. I dont know how to do that when handling a directory, and not only an UploadedFile file. What I have so far is this: def csv_retriever(request): if request.method == 'POST' and request.FILES['folder']: # encoding could happen here with the entire folder for file in request.FILES.getlist('folder'): # or here with the current file calculations(file) return render(request, 'price_calculator_started.html') -

Input data in german data format combined with ChartsJs
I'm relative new to Charts.js, but I'll need it to create some nice graphs for my webpage. In the background I have a Django project running which computes me a certain amount of numbers. Since I've put the language code in Django to "de-at" (requirement, since there are some input variables to fill in by austrian users), the number formats are done like: "1.000.000,54€" and not the US-way like "1,000,000.54€". If I now want to add some of my data into charts.js, it won't read the data, which has more than 6 digits. Furthermore, if there is a number like "653.598,36" it takes actually two parameters, namely (653,598 ; 36). Formatting the numbers in python does not help, since charts.js won't use strings for the graphs. Using the setting "locale = 'de-DE'" in the charts.js options only helps for labelling propertes, not for the data itself. If I change the Django setting back to "en-us", charts.js works with the numbers, but than my numbers on the webpage are not formatted correctly for the end-user. Has someone experienced this problem and has a solution to it? Thank you and best regards! Here is the code of charts.js with example values. I … -

Need Django Query optimization (2 Queries instead of 21)
I have a Django project on EBS and one query takes a pretty long time. I'd like to optimize it so that it's just one or two queries but I'm not sure if it's even possible. Models: WebSite,Article The query is a list of Articles from different websites. WebSite model has a home_order and home_article_count attributes that are used to select a number of articles and in which order they are. Example for websites A, B and C: A - A.home_order = 2, A.home_article_count=3 B - B.home_order = 1, B.home_article_count=5 C - C.home_order = 3, C.home_article_count=7 The result would be (aA means an article from website A): aB,aB,aB,aB,aB,aA,aA,aA,aC,aC,aC,aC,aC,aC,aC The lists starts with aB that means articles from website B because B.home_order=1, there are 5 aB articles as B.home_article_count=5. Right now, this is a Manager method that returns the articles: def home(self) -> QuerySet: articles_pks = [] for ws in WebSite.objects.active().order_by('home_order', 'name'): articles_pks.extend(ws.articles.filter(is_active=True).order_by('-created')[:ws.home_article_count].values_list('pk',flat=True)) return self.get_queryset().filter(pk__in=articles_pks) That means, for 20 WebSite objects, there is 21 queries (one that gets the websites and the other 20 for articles). Is it possible to merge it into one or two queries while respecting the WebSite.home_order and WebSite.home_article_count? -
How to sort column with dates from sqlite3 django with js datatables

Django: Can I have access to client cookies on first page load?
I need to read a cookie set by Google in order to render my homepage view. But I noticed that, on first load, the object request.COOKIES is always empty. I'm not sure if this is normal, my logic says "when you have a new visitor, all cookies are empty by default, so this is normal", but then, how do tools like Google Optimize work? Is there any way to wait for all client cookies to be set before rendering a view in Django? or will this never be something you'll want to do? I'm having a rough time trying to make an A/B to test work, but I'm starting to think that my approach of reading the cookies on first load was destined to never work. Can someone give me some piece of advice here? -

Any Idea? myjs.js const skladnikBox= document.getElementById('wybieraj'); const modalTytul=document.getElementById("exampleModalLabel") skladnikBox.addEventListener( 'change', e=>{console.log( event.target.value ); const skl=event.target.selectedOptions[0].text; console.log(skl); modalTytul.innerText=event.target.selectedOptions[0].text; `` $("#exampleModal").modal('show'); ////////////////ajax/////////////////////////////// $.ajax({ type: 'GET', url: `formJson/${ skl }/`, success : function(response){ console.log('success', response); // // const skladnikForm = response.data }, error : function (response){ console.log('error', error)} }) /////////////////////ajax///////////////// skladnikBox.selectedIndex = 0; }) views.py def formJson (request,skl): forms={'witamina A':VitAForm,'witamina E':VitEForm,'Hydrokortyzon': HydrokortyzonForm} form=forms[skl] context={ 'form':form} return JsonResponse(context) urls.py from django.contrib import admin from django.urls import path from . import views urlpatterns = [ path('', views.home,name='home'), path('formJson/<str:skl>/', views.formJson, name='formJson') ] -
Django dynamic url in root domain overwrites all other urls
I want to have a dynamic root url for different users. All users get their own url. I want to have the dynamic url in the root but also be able to have more hardcoded urls as alternatives, for example on the url that the user will edit their profile. The problem i have is that all urls redirect to view2 and none goes to view1. path(r'edit/<str:user>/', views.view1, name='view1'), path(r'<str:user>/', views.view2, name='view2'), example.com/edit/user always gets redirected to example.com/user which is not wanted.
