Django&REST-framework architecture
Hello I am tasked with translating a current Excel tool to a web application. I decided to use Python and Django. Lately I studied the Django REST framework. I have the following related questions. Is it for such an application a good idea to first write a web REST API so that I firstly only need to focus on the backbone of the web application. I.e. implement the PUT, POST, GET and DELETE methods and the Django models. The second step would be to implement the user interface... But if this is a valid method how can I reuse the REST views??? I followed the REST tutorials, but they don't show how to build a nice slick user-interface on top of the REST API. Since REST views inherit from Django, I think it's maybe not such a good idea to write a Django view which inherits from a REST Apiview? Or can I directly use an API endpoint in a template. If so where can I get some nice examples? -
Django: Graphviz generation with model names only?
I'm using Graphviz in Django (via django-extensions) to generate graph models. I'd like to generate graphs in two distinct ways: App by app in details (1 app per graph) -> no problem, it's done. All my models from all my apps, but without attributes (only model names) -> is it possible? I didn't find a way to do it in the documentation. If there is no way, I guess I could take a look to the source code, but not sure about the difficulty to do this. Thanks. -
Images are not displayed on web-page (Django)
the problem is this, using Bootstrap 3, created the "Carousel" from the images, then in Views wrote a loop that adds all the images with paths to the dictionary, then through the loop, output all the images in HTML-views.

Query different field than defined in return for a ManyToMany field option
I am new to Django and have a problem that I am trying to fix. In my application I have a model Asset which has multiple choice answer from AFF.

If you try to use serializers.SerializerMethodField, DRF would not let you use it on multiple results. SerializerMethodField doesn't support an option many AKA serializers.SerializerMethodField(many=True) I should note here that one could write a method that cycles through the results and accumulates them into a string, but that limits you from further … -

I don't know how to render entries of my models properly in Django template
I have a Course model from which I render my courses in the template. It also allows me to paginate or search through them. But I also want to sort the courses by faculty or by study programme (other models) and be able to paginate or search through them as well. Basically I want that by clicking, for example, on faculty name on the left column, the content on right column will be replaced with the courses of that faculty, and they will also have pagination and be searchable. I think is easy, but I don't have any idea yet. def index(request): query_list = Course.objects.all() query = request.GET.get('q') if query: query_list = query_list.filter(Q(name__icontains=query)) paginator = Paginator(query_list, 1) page = request.GET.get('page') try: courses = paginator.page(page) except PageNotAnInteger: courses = paginator.page(1) except EmptyPage: courses = paginator.page(paginator.num_pages) context = { 'courses': courses, 'faculties': Faculty.objects.all(), 'departments': Department.objects.all(), 'studies': StudyProgramme.objects.all(), 'teachers': Teacher.objects.all() } return render(request, 'courses/index.html', context) <div class="container-fluid"> <div class="row"> <div class="col-md-3"> <div class="jumbotron"> <h4>Sort courses</h4> <hr> <br> <ul> {% for faculty in faculties %} <li><a href=""> {{ faculty.name }}</a></li> {% for department in faculty.department_set.all %} {% for study in studies %} <ul> {% if study.department == department %} <li>{{ study.name }}</li> {% endif … -

Multi select input in admin site
I am trying to create a form in Admin site that uses two fields from two different tables as input (single select & multi-select) and make it available for admin user selection and write this to another table. Following is my code. models.py class Employee(models.Model): id = models.IntegerField(primary_key=True, verbose_name='Employee Code') name = models.CharField(max_length=200, verbose_name='Employee Name') def __str__(self): return self.name class Product(models.Model): STATUS = (('New', 'New'), ('Go', 'Go'), ('Hold', 'Hold'), ('Stop', 'Stop')) code = models.IntegerField(primary_key=True, max_length=3, verbose_name='Product Code') name = models.CharField(max_length=100, verbose_name='Product Name') def __str__(self): return self.name class JobQueue(models.Model): emp_name = models.CharField(max_length=200, default='1001') product_code = models.CharField(max_length=200, default='100') admin.py: class JobQueueAdmin(admin.ModelAdmin): form = JobQueueForm fieldsets = ( (None,{'fields': ('emp_name', 'product_code'),}),) def save_model(self, request, obj, form, change): super(JobQueueAdmin, self).save_model(request, obj, form, change) forms.py: class JobQueueForm(forms.ModelForm): emp_name = forms.ModelChoiceField(queryset=Employee.objects.all(), widget=forms.ChoiceField()) product_code = forms.MultiValueField(queryset=Product.objects.all(), widget=forms.CheckboxSelectMultiple(), required=False) def save(self, commit=True): return super(JobQueueForm, self).save(commit = commit) class Meta: model = JobQueue fields = ('emp_name', 'product_code') When I start the web-server, I get the following error: AttributeError: 'ModelChoiceField' object has no attribute 'to_field_name' Can someone please shed some light on how do I get this form right? -
Django-allauth How to Ban Certain Users?
I'm using django-allauth for my Django web app. How can I ban certain users from logging in or restrict certain actions after they log in for a period of time? Should I just deactivate their accounts outright? What are some good solutions? -
Using Google/G-Suite as a user backend for django?
I'm looking at building a django app specifically designed for G-Suite domains. It requires users to be logged in to G-Suite, and would get permissions from groups in G-Suite. I know I could achieve this using django-allauth or similar, but that would involve the django app duplicating the user information in it's own database. In the interests of preventing unnecessary replication, is it feasible to have django directly use Google APIs to handle user logins, but still program the rest of the app in a django kind of a way? Are there any libraries that implement this? If not in django, are there other (python) frameworks that can do this? -
