Dynamically chained forms with AJAX
I have two models: class ModelA: field = models.ForeignKey(ModelB) class ModelB: group = models.CharField(choices=GROUPS) subgroup = models.CharField(choices=SUBGROUPS) I have a CreateView for ModelA which i'm trying to dynamically filter with AJAX: class ModelACreateView(CreateView): def get_context_data(self, *args, **kwargs): context = super().get_context_data(*args, **kwargs) context['groups'] = GROUPS // Populate fields in template context['subgroups'] = SUBGROUPS return context def get_form_kwargs(self, **kwargs): kwargs = super(ModelACreateView, self).get_form_kwargs() kwargs.update(request=self.request) // Pass request to a form return kwargs Then in forms: class ModelACreateForm(forms.ModelForm): def __init__(self, *args, request=None, **kwargs): super(ModelACreateForm, self).__init__(*args, **kwargs) group = request.GET.get('group') // Get data from AJAX request subgroup = request.GET.get('subgroup') qs = ModelB.objects.filter(group=group, subgroup=subgroup) self.fields['field'].queryset = qs Here's the script: $("#group_select, #subgroup_select").change(function () { var endpoint = "{% url 'new_model' %}"; // URL to CreateView var group = $("#group_select").val(); var subgroup = $("#subgroup_select").val(); $.ajax({ url: endpoint, data: { 'group': group, 'subgroup': subgroup, }, success: function (data) { $("#id_field").load(" #id_field"); } }); }); But i'm having a problem reloading the field: it renders empty. When i check logs, i see that the form gets the group, loads qs, but then i see another GET request, which doesn't have group from AJAX and i get rendered empty form field. How do i rewrite the AJAX correctly? -

Django - Modify a generic detail view to manage a form and post data - Django
On a webpage, i want to display information about a specific object and have a form to send a message about this object. At the beginning, i used a detail view to display the info about the object. Then a created a message form based on my Message Class I used get_context_data to pass the form in the context for the template. I would like to know if there is a way to manage the validation of the form in the same view or should i come back to a function view? My view: ' class LoanDetailView(DetailView): model = Loan def get_context_data (self, **kwargs): context = super(LoanDetailView, self).get_context_data(**kwargs) msg_form = MessageForm() context['msg_form'] = msg_form return context ' In my template: <form method="POST"> {%csrf_token%} <fieldset class="form-group"> {{ msg_form | crispy }} </fieldset> <div class="form-group"> <button class="btn btn-outline-info" type="submit"> Envoyer </button> </div> </form> -
Standardising get_success_url
For my classes PostCreateView and PostUpdateView I have the same get_success_url. Is there a way of standardising your get_success_url, I want to avoid writing the code twice? def get_success_url(self): return reverse('post-detail', args=[self.object.pk]) I was working through a tutorial. A limitation of the tutorial though was you were only shown how to load posts by using the posts primary key (https://rossdjangoawesomeapp2.herokuapp.com/post/6/). I modified the code in the tutorial so you could access posts using their title (https://rossdjangoawesomeapp2.herokuapp.com/post/another-test-please-let-it-work/). Which has resulted in me having duplicate code. models.py class Post(models.Model): title = models.CharField(max_length=100) content = models.TextField() date_posted = models.DateTimeField(default=timezone.now()) author = models.ForeignKey(User, on_delete=models.CASCADE) url = models.SlugField(max_length=500, blank=True) def save(self, *args, **kwargs): self.url= slugify(self.title) super().save(*args, **kwargs) def __str__(self): return self.title def get_absolute_url(self): return reverse('post-detail', kwargs={'pk': self.pk}) views.py class PostCreateView(LoginRequiredMixin, CreateView): model = Post fields = ['title', 'content'] def get_success_url(self): return reverse('post-detail', args=[self.object.pk]) def form_valid(self, form): form.instance.author = self.request.user # will save the form and redirect to the success_url return super().form_valid(form) class PostUpdateView(LoginRequiredMixin, UserPassesTestMixin, UpdateView): model = Post fields = ['title', 'content'] 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 return False def get_success_url(self): return reverse('post-detail', args=[self.object.pk]) -
Cleaner way to populate data while adding a record
I was wondering if there is a better way to create a record when you have to add data to a lot of fields. country.objects.create(name=name, population=population, code=code, mobile_code=mobile_code, ...) # imagine 10 more fields that have to be filled Moreover, if the field value is none, then use the default value as specified in the model. for example if population variable is None, then don't make population=None, use the default value. -

Best way to store Machine Learning Models in a django app?
I am trying to build a Django app where a user can upload a CSV file and a sklearn linear model will be created and trained to that dataset. So, each time a new CSV file is uploaded a new model will be created. My question is what is the best way to go about storing these generated models for later use in Django so that users could later choose which model they wanted to use? I have seen some suggestions for pickling them using cpickle and also using Django's cache framework, how would these options affect performance? -
Combine two Django Querysets based on common field
I have two Querysets (actually, list of dicts) like: q1 = M1.objects.filter(id=pk).values('p_id', 'q1_quantity') # q1: <Queryset[{'p_id': 2, 'q1_quantity': 4}, {'p_id': 3, 'q1_quantity': 5}]> q2 = M2.objects.filter(p_id__in=[q1[x]['p_id'] for x in range(len(q1))]).values('p_id', 'q2_quantity') # q1: <Queryset[{'p_id': 2, 'q2_quantity': 2}, {'p_id': 2, 'q2_quantity': 5}, {'p_id': 3, 'q2_quantity': 1}, {'p_id': 3, 'q2_quantity': 7}]> q1 has distinct key:value pairs, while q2 has repeated keys. 1) I want to sum all the values of q2 by common p_id, such that q2 becomes: # q2: <Queryset[{'p_id': 2, 'q2_quantity': 7}, {'p_id': 3, 'q2_quantity': 8}]> 2) Then, merge q1 and q2 into q3, based on common p_id, like: q3 = ? # q3: <Queryset[{'p_id': 2, 'q1_quantity': 4, 'q2_quantity': 7}, {'p_id': 3, 'q1_quantity': 5, 'q2_quantity': 8}]> I have looked into union(). But don't know how to go about summing the queryset (q2) and then merging it with q1. Can someone please help me? -
Django shell does not let me query models
I am trying to query my customized user model "RmkUser" through the django shell, but it keeps raising an error when I try to command "from models import RmkUser": RuntimeError: Model class models.RmkUser doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS. I am not sure why it does this, nor was I able to find out through other posts. I saw that there are a lot of posts which show problems with this error, too, but I can't find a solution for my specific case. I don't understand why django asks me to declare my customized user model "RmkUser" under INSTALLED_APPS. After all, its a model, not an app. My app (as opposed to the "RmkUser" model), however, is entered under INSTALLED_APPS and it also has an app_label. Also, I did set AUTH_USER_MODEL to my customized user model. Not only that, but my site is actually running completely fine when I "python manage.py runserver". I can create new users, log in, etc, no problem. Does anybody know how I can get the shell to let me query the "RmkUser" model? Thanks in advance! -

django docs starter app - allow users to create a new poll
I am learning django and I have followed the starter poll app in the docs they provided. I have extended it and have added into a login / register system and I want to make it so that users who are logged in can create a new poll just like how I can do it in the admin panel (obviously without being able to set a date and amount of votes for each choice.) In the admin.py file admin.TabularInLine is used which does not seem right to use for anything else. I have tried looking around for answer and I have had to resort to asking here.Ive attached a screenshot of the admin panel to showwhat I mean. my admin.py from django.contrib import admin from .models import Question, Choice class ChoiceInLine(admin.TabularInline): model = Choice extra = 3 class QuestionAdmin(admin.ModelAdmin): fieldsets = [ (None, {'fields': ['question_text']}), ('Date information', {'fields': ['date_posted']}) ] inlines = [ChoiceInLine] list_display = ('question_text', 'date_posted', 'was_published_recently') list_filer = 'date_posted' admin.site.register(Question, QuestionAdmin) my models.py from django.db import models from django.utils import timezone import datetime from django.forms import ModelForm from django.forms.models import inlineformset_factory class Question(models.Model): question_text = models.CharField(max_length=200) date_posted = models.DateTimeField('Date published') def was_published_recently(self): now = timezone.now() return now - … -

Replace Django-CMS plugin instances with another plugin
Excuse me, if I'm not using the right "django terminology", but I am new to django. I am workin on a website which uses Django CMS and is not responsive. They use different plugins to layout the content. One of them is djangocms_columns to realize multicolumns. Those columns unfortunately are not responsive. I already brought Bootstrap to most of the site but would love to avoid having to replace the multicolumn element on every page. So my idea was one of the following and couldn't find out if it is possible at all. Idea 1 - Overwrite the templates of djangocms_columns The site currently works with width settings in percentage. I'd like to replace those with the col-*-classes of bootstrap. Is it somehow possible to overwrite the templates of a plugin? As far as I understand, this is not a good way to go, so I would prefer the following idea. Idea 2 - Replace the plugin instances with bootstrap-4 plugin instances I found this django cms bootstrap 4 plugins and looking forward to editing the website, I would prefer to replace the multicolumn plugin with this one. Is there a possibility to once replace all multicolumn instances with bootstrap4-row … -

Deploying Django REST API with Heroku [GET request, infinite loading]
So I'm currently working on a project which looks like: - project-d/ - api/ - app/ - web/ We're focussing on deploying everything inside the api/ folder onto Heroku first. This is where the Django project is located. Steps that I have taken so far: Created a new node on Heroku Added ENV variables (including: DISABLE_COLLECTSTATIC=1, since I don't have static files). My Database (PostgreSQL) is running on a Digital Ocean droplet inside a Docker container (the ports are open). Connect the git project to Heroku (heroku login, heroku git:remote -a special-park) Added the domain of the Heroku project in the ALLOWED_HOSTS in settings.py (see the file here: https://github.com/buzzzlightyear/special-park/blob/deployment/api/specialpark/settings.py) I used Pipfile so there was no need for requirements.txt Added runtime.txt containing python-3.7.6 Added Procfile containing web: gunicorn specialpark.wsgi --pythonpath=specialpark --log-file - Now I pushed everything on to Heroku, since we only want the subdirectory to be deployed I ran this command: git subtree push --prefix api/ heroku master Response: ➜ project-d git:(deployment) git subtree push --prefix api/ heroku master git push using: heroku master Enumerating objects: 5, done.

Django Rest Framework - Register User POST without providing Authentication credentials
I'm trying to write a simple code in my app to register users (it's a custom user that inherits from AbstractUser) using Django Rest Framework. If I post it using the web interface (through localhost:8000/api/v1/pacientes) it works perfectly, I can create normally. However if I try using POSTMAN, for example, I get a {"detail": "Authentication credentials were not provided."} as response. It seems like I'm not providing any Authentication, however this view is for the user to register himself in my app through the frontend, so he's not Authenticated yet. This is driving me crazy, so if anyone has a workaround for it, that would be amazing. urls.py: router = DefaultRouter() router.register('paciente', paciente.PacienteViewSet) urlpatterns = [ path('', include(router.urls)) ] views.py: class PacienteViewSet(viewsets.ModelViewSet): serializer_class = UsuarioPacienteSerializer queryset = Usuario.objects.all() serializers.py class UsuarioPacienteSerializer(serializers.ModelSerializer): def create(self, validated_data): user = Usuario.objects.create_user( username=self.validated_data['username'], email=self.validated_data['email'], tipo_usuario=Usuario.PACIENTE, ) user.set_password(validated_data['password']) user.save() return user class Meta: # model = Paciente model = Usuario fields = ('id', 'username', 'email', 'password') extra_kwargs = { 'password': { 'write_only': True, } } -
update an object with UpdateView and without DetailView Django
I'm looking for a solution to update an object without having to go to the detail page but, just edit it on the page itself. What I want to achieve is when I click on edit: the object becomes a field where I can edit and save it. All the YouTube tutorials show the edit->detail page version. I'm getting an error now because I'm trying to do the same approach as by the delete view and understand that it wants me to edit the object on a separate page. I would like to get some help or tips on this. The error urls.py from django.urls import path from .views import ( HomePageView, TaskCreateView, TaskDeleteView, TaskUpdateView, ) urlpatterns = [ path('', HomePageView.as_view(), name='home'), path('task_new/', TaskCreateView.as_view(), name='task_new'), path('<int:pk>/task_delete/', TaskDeleteView.as_view(), name='task_delete'), path('<int:pk>/task_edit/', TaskUpdateView.as_view(), name='task_edit'), ] views.py from django.views.generic import ListView from django.views.generic.edit import CreateView, DeleteView, UpdateView from django.urls import reverse_lazy from .models import Task class HomePageView(ListView): model = Task template_name = 'home.html' context_object_name = 'all_tasks_list' class TaskCreateView(CreateView): model = Task fields = ['text',] class TaskDeleteView(DeleteView): model = Task success_url = reverse_lazy('home') class TaskUpdateView(UpdateView): model = Task fields = ['text',] home.html <!DOCTYPE html> <html> <head> <title>Todo app</title> </head> <body> <h1>Todo app</h1> <ul> {% for …
