Django Tables 2 Filter field, but use the display name?
I've got this model: DRAFT = 'draft' IN_PROGRESS = 'in_progress' FINISHED = 'finished' STATUS_CHOICES = ( (DRAFT, 'Entwurf'), (IN_PROGRESS, 'In Arbeit'), (FINISHED, 'Erledigt'), ) class Invoice(TimeStampModel): status = models.CharField('Status', choices=STATUS_CHOICES, max_length=50) and this filter I've build with the django tables 2 plugin: class InvoiceFilter(django_filters.FilterSet): class Meta: model = Invoice fields = { 'name': ['icontains'], 'status': ['icontains'], } My filter gets rendered without a problem on my page and I can use it. The problem right now is though if I try to search for a status using the german word, like for example Entwurf the filter always returns me no item. BUT if I filter for draft I get all the items which have this status. So my question would be: how can I tell my filter to look for the display name of my status field? Or even better: would it be possible to just make a select out of the status field instead of a normal search? Thanks for any answers! -

django admin like behaviour for app users
We have merchants with campaigns in our project. Currently, we - as superuser - manage all merchants' campaigns. However, some merchants require access to campaign management so that they can control the process and set new campaigns themselves. There is a possibility to create the second admin site and set permissions so that only merchants can log in. However, what we need is - to filter only the campaigns owned by logged in merchant and also, when creating a new one the merchant_id should be prefilled and readonly. Is it possible to do it using the second django admin site or should I create a special frontend interface for this purpose? Is it possible to set permissions per user-object pair (in django admin)? -
Is there a good way to mirror external (not model) DB table to django.contrib.auth.models.User?
I have a software that is written in Java that I can not modify. Because of it I'm making a wrapper in Django that will use said software's REST API. I'm new, but I learn as I go. I require exactly the same user ids and emails - they have to be mirrored from Java program's user table to django.contrib.auth.models.User. I thought about doing it by creating a database-side event that would periodically (every hour?) fill my django.contrib.auth.models.User with users that Java software created. I'm pretty sure this is not very efficient, since: It needlessly strains the database that is under a large stress as it is It's too slow, I would much prefer mirror to happen as soon as Java app creates an user Letting Django do it would probably be much cooler + would be more obvious for my replacement in case I leave my company That event will have to constantly move hundreds of users - this can't be good Does anyone have a better idea? Maybe I'm not looking at it correctly, or even overthinking it? -
Validation: clean() and clean_<fieldname> not working as expected
I have to validate a field if it's unique. I am not using unique=True in models. I am using clean() and clean_() in forms but are raising different errors. forms.py Case 1: clean() name = forms.CharField(widget=forms.TextInput(attrs={'placeholder': 'Enter Package Name', 'class': 'form-control'})) def clean(self): name = self.cleaned_data.get('name') if Package.objects.filter(name=name): raise ValidationError(_("Package with this package name already exist.")) return name case 2: clean_name() name = forms.CharField(widget=forms.TextInput(attrs={'placeholder': 'Enter Package Name', 'class': 'form-control'})) def clean_name(self): name = self.cleaned_data.get('name') if Package.objects.filter(name=name): raise ValidationError(_("Package with this package name already exist.")) return name views.py package.name = form.clean_name() or package.name = form.clean() in html template: <p style="color:red;">{{ form.non_field_errors.as_text }}</p> Problem: in case 1, validation is correct if I send duplicate name but if name is unique, this gives this error: 'str' object has no attribute 'get' In case 2: if name is valid, then everything ok. data is saving normally but if it's duplicate data, it's not showing error message. But validation is working as it's not submitting the form. -
Creating video thumbnails with imagekit and opencv
I have a model named "Post", which is going to refer to images and videos. I added ImageSpecField for thumbnail storage and created a function, that pulls the desired frame from uploaded video. Is there any way to use this function while generating thumbnail? Because right now ImageSpecField can only use FileField as an input. I have tried creating a new class inheriting from ImageSpecField, but I quickly realized that this is not going to work because this class was instanced only on server start, thus putting this function in constructor of it would not work. import cv2 as cv from django.conf import settings from django.db import models from imagekit.processors import ResizeToFit from imagekit.models import ImageSpecField def video_to_image(source, frame): vid_cap = cv.VideoCapture(settings.MEDIA_ROOT + source.__str__()) vid_cap.set(cv.CAP_PROP_POS_FRAMES, frame) success, image = vid_cap.read() vid_cap.release() return image class Post(models.Model): IMAGE = 'I' VIDEO = 'V' FILE_TYPES = [ (IMAGE, 'Image'), (VIDEO, 'Video') ] file_type = models.CharField(max_length=1, choices=FILE_TYPES) file = models.FileField(upload_to='post_images') thumbnail_frame = models.IntegerField(default=0) image_thumbnail = ImageSpecField(source='file', processors=[ResizeToFit(width=200, height=200)], format='JPEG', options={'quality': 60}) I want imagekit to generate thumbnail from video, and be able to get it via ImageSpecField. -
setting get_absolute_url when using a router
I'm working on a Comment app and I would like my Commentserializer to display the exact URL of each instance of Comment. I know that I have to use the get_absolute_url of the Comment model. But i cannot connect my viewnames from my router to the get_absolute_url. Here is my Model : class Comment(models.Model): content = models.TextField(max_length=150) author = models.ForeignKey( User, on_delete = models.CASCADE ) content_type = models.ForeignKey(ContentType, on_delete=models.CASCADE) object_id = models.PositiveIntegerField(blank=True) content_object = GenericForeignKey('content_type', 'object_id') parent = models.ForeignKey( "self", on_delete = models.CASCADE, blank=True, null=True ) datestamp = models.DateTimeField(auto_now_add=True) objects = CommentManager() def __str__(self): return str(self.content[:30]) def save(self): self.object_id = self.parent.id super(Comment, self).save() def children(self): return Comment.objects.filter(parent=self) def get_absolute_url(self): return reverse("comments-details", args=[str(self.id)]) @property def is_parent(self): if self.parent is None: return False return True and here is my router : router = router = routers.SimpleRouter() router.register('api/comments', CommentViewSet) urlpatterns = router.urls As you can see, I'm trying to use "comment-details" as a viewname. The end Goal is to display a JSON like that : { url : 'blabla/comments/{pk}/details } -
How to get parameter from user front-end in Django generic.ListView?
I am building an app where users will be able to search nearby locations. For this, I am using this function in my views.py: latitude = 23.734413 longitude = 90.4082535 user_location = Point(longitude, latitude, srid=4326) class NearbyServices(generic.ListView): model = Service context_object_name = 'services' queryset = Service.objects.annotate(distance=Distance('location', user_location)).order_by('distance')[0:6] template_name = 'services/nearby.html' I am currently using a hard-coded user location, but I want to let the users find nearby locations by first getting their location using the HTML5 GeoLocation API. Any help with how I can get their location from the front-end into the listview function would be really helpful! -

Django Rest & React: lookup_field = 'slug' not returning item from db
I'm trying to return items from my sqlite db such that the url in the browser reflects the slug, rather than the unique post id. I had this working before by using the primary key, whereby items were returned from the db when clicking a hyperlink for item detail - but swapping everything out for slug is not working. I have a PostListView in react which lists my items from the db successfully, when I click on one of these the url field in the browser properly shows the slug. However, no data is returned from the db in the underlying detail view. I am using django 2.2.1, django rest framework and react. Back end - django and rest framework modules: Models.py class Post(models.Model): post_id = models.UUIDField( primary_key=True, default=uuid.uuid4, help_text='Unique ID for this post') title = models.CharField(max_length=100) content = models.TextField() publish_date = models.DateTimeField(auto_now=True) slug = models.SlugField(default='') api/views.py class PostListView(ListAPIView): queryset = Post.objects.all() serializer_class = PostSerializer class PostDetailView(RetrieveAPIView): queryset = Post.objects.all() serializer_class = PostSerializer lookup_field = 'slug' api/urls.py urlpatterns = [ path('', PostListView.as_view()), path('<slug>', PostDetailView.as_view()), ] api/serializers.py class PostSerializer(serializers.ModelSerializer): ''' Serialisers will convert our JSON from web into python model ''' class Meta: model = Post fields = ('post_id', 'slug', 'title', … -

Recommended Web Technology for an e-commerce product
I need help in choosing the right technology stack for my client's project. The website will provide services for pets by connecting the pet owner to the pet sitter. There will be no physical products to sell on the website. It will be just services like walking, grooming., etc for the customer to choose from the website. The website will primarily connect the pet walker or the pet sitter to the customer in getting these services. https://www.rover.com is a good example of what I am trying to build. We will also be building mobile apps for the same. My experience is mostly in Python and PHP. I have worked primarily on Django, Magento and Codeigniter based projects. But now I started learning NodeJs and I started liking it. So I thought of trying this new website using MEAN stack. But I am not sure if NodeJs is right for such a website. Or should I just stick to Django?
