Django - Displaying model data on Elasticsearch search result
I am making a booking website, and I have implemented elasticsearch. I got the search working just fine, but now I am kind of stuck on a problem.

Sending input names in Django form having javascript code
I have the following code: <form id="buttonForm" action = "/goSomeWhere" method="post" > <input type="submit" name="bnext" value="Next Page" > <input type="submit" name="bprevious" value="Previous Page" > </form> When either one of this two buttons are submitted I receive "bnext" or "bprevious" values in Django View request.POST so I can further construct the logic that I need.

Can't login with super user created account in Python 3.8
Before i go forward, I know this is a commonly asked question but I have searched the top questions related to this, and none of it seems to be helping.. Following: https://docs.djangoproject.com/en/2.2/intro/tutorial02/ What I have done: py manage.py createsuperuser Created user I have confirmed the user is a superuser with: from django.contrib.auth.models import User active_staff = User.objects.filter(is_active=True, is_staff=True) This will then list the super users Although, when I do something like: u = User(username="admin") u.is_staff >> False u.is_superuser >> False Why is this? I also then manually set to true, save(), then check, and it's now True. Try to log in, doesn't work. restart shell and check, it's back to false. I tried the accepted answer here: Can't login to django admin after creating a super user with a custom user model This: Admin page on django is broken None have helped. If there is anything i need to copy/paste from my Djnago app to help, pleaes let me know. I am new with Python and Django so I'm not exactly sure what to add to this question. -

Django form from JavaScript
I'm trying to create a server using Django where the user creates figures such as markers, lines, polygons, circles, etc in a map, because of that I'm using Leaflet.js. After the user creates what he wants I want the geometry figures (Latitude and Longitude of every figure) and Leaflet have an option for that, however you must download but I don't want so I changed a part of the source code into this. document.getElementById('export').onclick = async function(e) { var data = drawnItems.toGeoJSON(); // make the request: var rsp = await fetch("path/to/server/upload/url", { method: "POST", headers: { 'Content-Type': 'application/json' }, body: JSON.stringify(data), }); console.log("server responded with: ", await rsp.json()); } I'm not good at web developing so I lack of knowledge using Django and JavaScript. So my question is the following (probably a noob question): Is there a way to create a form for the geometry figures in order to manipulate it in Python?

How to change django admin permissions based on a field value?
I have a model where a Professor belongs to a certain department Class Professor(models.Model): name=models.CharField(max_length=50) code=models.CharField(max_length=9) dept=models.ForeignKey('Department', on_delete=models.CASCADE) Where the model for the department is just its name with multiple professors pointing to it. Would there be a way to set view or edit permissions depending on the value of the department name?

How to provide read-only access for unauthorized users to my React/Django app?
I have a social media-type web app and want to have some read-only access even when a user isn't logged in. For example, if the user votes on a poll, I want nothing to happen but the user should still be able to see it. I am using token authorization. I'm wondering, should I do a check on the front-end somehow to see if a user is logged in (perhaps checking for the existence of a token in local storage) and not perform a fetch if they're not? Or should I somehow, in the frontend, handle receiving a 401 response from the backend for trying to access a protected resource? Or should I handle it on the back end and send back a 200 response and let the front end handle receiving a different version of a 200 response? I'm using Django and React -

How do I set up a ThemeForest theme in a Django project?
I recently got started with Django, took a few courses on it and got the basic idea in terms of project structure, urls, templates, static files etc. To avoid learning frontend development (and build my app faster), I thought a bootstrap theme would be a good option. I got this https://themeforest.net/item/metronic-responsive-admin-dashboard-template/4021469 which has bootstrap4 in the title, however, it seems that integrating it into the project is not as simple as placing the scss, js and vendor files into my static folder. The 'getting started' resources suggest that it runs on NodeJS, and has a whole backend of its own. I'm not asking for a bespoke full guide on how to do it, but it'd be nice to know if the two things are compatible or I if should move on and try some other frontend solution instead. Cheers! -
Transfer date and time from Django model to Javascript and save the object again
I have a serializer class and a view which convert Django model and it can be shown in a template. # models.py class Book(models.Model): title = models.CharField(max_length=65, null=True, blank=False) published_at = models.DateTimeField(blank=True) # serializer.py class BookSerializer(serializers.ModelSerializer): published_at = serializers.SerializerMethodField() def get_published_at(self, obj): published_at = obj.published_at return published_at class Meta: model = Book fields = ('title', 'published_at') Using the serializer class, one can send the data to a template. Here, the value of published_at is in the ISO date format. Such as: 2019-10-17T21:57:56Z I need to show it in an HTML/Javascript form as local time and then again send the date object to Django to update the published_at field. How can this be achieved? -
Is there a way to reload ViewSet on each GET request for new data in DRF?
I am trying to generate a random object from my Model. The problem is that it will only work one time, then I have to restart the server to get a new object. It just keeps giving me the same object until the restart. I have been looking for solution on stack overflow but haven't found any. Views.py def dailyaskist(category): qs = Task.objects.filter(category=category) max_num = len(qs) while True: pk = random.randint(1, max_num) task = Task.objects.filter(pk=pk).first() if task: return task.pk class DailyTaskEcommerceViewSet(viewsets.ModelViewSet): category = 'ecommerce' task_pk = dailyaskist(category) queryset = Task.objects.filter(pk=task_pk) serializer_class = TaskSerializer serialisers.py class StepSerializer(serializers.HyperlinkedModelSerializer): task_id = serializers.PrimaryKeyRelatedField(queryset=Task.objects.all(), source='task.id') class Meta: model = Step fields = ('title', 'description', 'done', 'task_id') class TaskSerializer(serializers.HyperlinkedModelSerializer): steps = StepSerializer(many=True, read_only=True) class Meta: model = Task fields = ('title', 'description', 'video', 'done', 'steps') models.py Categories = ( ('ecommerce', 'Ecommerce'), ) class Task(models.Model): title = models.CharField(max_length=50) description = models.TextField(max_length=360) video = models.CharField(max_length=30, default='') category = models.CharField(choices=Categories, default='', max_length=30) done = models.BooleanField(default=False) def __str__(self): return self.title class Step(models.Model): task = models.ForeignKey(Task, related_name='steps', on_delete=models.CASCADE) title = models.CharField(max_length=50) description = models.TextField(max_length=360) done = models.BooleanField(default=False) def __str__(self): return self.title I want to receive a new object (task) each time I make a GET request using the DailyTaskEcommerceViewSet. Thanks in …
