Django Rest Framework - How to retrieve model properties (field name, field type) and input into Rest API as data to be collected?
I am currently working on a project that uses Django as the backend, with the rest framework acting as an API endpoint for the frontend (ReactJS) to collect data and ultimately, using ReactJS to render the entire UI. However, right now, I am facing the issue of rendering the form in ReactJS as I do not want to manually type in the field names and field types into the form tag in the ReactJS component. Hence, I am hoping that I would be able to extract the model properties from Django, and pass the field names and field types to the API endpoint, so that the ReactJS frontend would be able to get the data and render the form fields accordingly. I have thought about passing in data through a model Serializer, but in that case, if there are no instances of that model, then the JSON object returned would be empty. Alternatively, if there is no way to extract the model properties in Django, then would it be possible for me to pass in the data manually by creating a new Serializer and View? and manually type in the required field names and field properties to be sent over … -
Permission denied error with django-celery-beat despite --schedulers flag
I am running Django, Celery, and RabbitMQ in a Docker container. It's all configured well and running, however when I am trying to install django-celery-beat I have a problem initialising the service. Specifically, this command: celery -A project beat -l info --scheduler django_celery_beat.schedulers:DatabaseScheduler Results in this error: celery.platforms.LockFailed: [Errno 13] Permission denied: '/usr/src/app/celerybeat.pid' When looking at causes/solutions, the permission denied error appears to occur when the default scheduler (celery.beat.PersistentScheduler) attempts to track of the last run times in a local shelve database file and doesn't have write access. However, I am using django-celery-beat and appying the --scheduler flag to use the django_celery_beat.schedulers service that should store the schedule in the Django database and therefore not require write access. What else could be causing this problem? / How can I debug this further? -

How to get a queryset with first child product of a parent product?
I have this table(https://prnt.sc/s1ssxx), where I want to fetch all the products with structure standalone and only first variant(child) of a parent product. i.e(excluding all the products with structure "parent", and just keeping first child product of all parent products). from django.db.models import Count, F, Value parent_ids = Product.objects.filter(user_id=user_id,structure=Product.PARENT).values_list('id', flat=True) qs = Product.objects.filter(user_id=user_id).exclude(structure=Product.PARENT).annotate(p=F('parent_id')).distinct('parent_id') I tried this query, but I am using MySQL as Database backend, so it complains about error: "DISTINCT ON fields is not supported by this database backend" , it can only be used this way by other database backends such as Postgres so I can not use distinct with any field name. How can I fetch these records in an optimized way with minimum hits on DB? -
Django Model's Value Error while inserting data into model
I am trying to insert form-data into models User and UserGroup using APIView. class User(AbstractBaseUser, PermissionsMixin): email = models.EmailField(max_length=255, unique=True) first_name = models.CharField(max_length=255, blank=False, null=False) last_name = models.CharField(max_length=255, blank=False, null=False) profile_picture = models.ImageField(upload_to='profile_pictures/', max_length=None, null=True, blank=True) is_active = models.BooleanField(default=True) objects = UserManager() USERNAME_FIELD = 'email' class UserGroup(models.Model): user = models.ForeignKey(User, related_name='user_id', on_delete=models.CASCADE, blank=False) role = models.ForeignKey(Role, related_name='role_id', on_delete=models.CASCADE, blank= False) I am able to insert data into model User but when I try to do the same with the model UserGroup it returns an error. ValueError: Cannot assign "17": "UserGroup.user" must be a "User" instance. I want this API to create a user and assign a role immediately to the newly created user by inserting role_id and user_id in model UserGroup. I have created two different serializer UserSerializer and UserGroup serializer and both has its own create method to push an instance into model. Also, in post request payload I am accepting all the fields of User model but for UserGroup model I am just accepting role field and not the user field as its value needs to be generated once the user is created. I will have to use transaction as well to roll back if in case a … -

How to implement the tags in django similar to stackoverflow tags in django?
Im learning django 3(can build simple blogs) and trying to develop problem registering application. i was curios what things are involved to create tags like shown in screenshot (CCs email, tags) , when i enter email address and press enter it gets set , similarly when i enter some string and press enter the string is saved in Tag section. what is the field type used(in database model) for such and how relationship is handled (so far my understanding is it must be many to many as multiple Tag string can be associated to multiple issue but is it so simple like this ? ), how effective search can be implemented based on the tags and other bits/pieces of library implemented you know/use - I would appreciate suggestions and helpful links -
scroll websites with django
I'm currently working on a simple scroll website with nothing really difficult (I could almost use plain html/css/javascript but it's a bit of practicing and I will maybe add a blog). And as it is simple I was wondering how to do it properly with Django. So here is my question, I have a homepage template that is actually the website and I don't really get how I split my different part in different apps. For exemple I have a contact form, do I need to split it in another app and then include it in the basic template ? I want to add a galery with image in a database, do I create an app for that ? And the other question that goes along is how do I code an app that is not returning httpresponse but just html to put it in another template and do I still need views ? I would like to do a bit like a standard form in django where you do : form.as_p or form.as_table so maybe: galery.as_slideshow So my questions are quite novice and open but someone could give me some reading to get going, I would be really happy … -

Django 2.1.5: Storing the current username in a blog entry
I am very new to Django and try to build a little app for my family with some basic features, one of which is a blog app. In this now I want to store the author of a blog entry in the article model to save it in the database. In the end in the blog entry I want a header that displays the author and the datetime. I found several approaches to that but some how none of them worked for me so far. The last thing I did now was to try and grab the username in the view with requests.user.get_username() and then populate the field in my form with this string as initial value. Somehow it just doesn't come through, I always get the "field is required" error message... Here is my blog-create-view.py: def blog_create_view(request): user = request.user.get_username() data = {'author': user} form = BlogForm(request.POST, data) if form.is_valid(): form.save() return HttpResponseRedirect('/blog/blog-create/thanks') else: print(form.errors) form = BlogForm() context = { 'articleform' : form, } return render(request, "blog-create.html", context) this is the form: class BlogForm(forms.ModelForm): title = forms.CharField(label='', widget=forms.TextInput(attrs={"placeholder":"Titelfeld"})) text = forms.CharField( label='', widget=forms.Textarea( ) ) author = forms.CharField(widget=forms.HiddenInput()) class Meta: model = Article fields = [ 'title', 'text', … -

Will I be able to use celery tasks during model migrations in Django?
I have a requirement to modify an existing db model called Alert and create new alerts with new functionality. I also need to take care of the existing alerts in the data base which were created with old model fields. After adding the new fields to Alert model, I'm trying to re-create the alerts with new functionality which has new columns. Basically taking existing rows and re-inserting them in data base with updated new columns with some extra information in the new columns. For this I'm trying to run a celery task in the function which is called as soon as the migration is applied. migrations.RunPython(function which does some operation and then run celerytask.delay(with_some_args) to create new alerts) I'm really concerned whether I can run a celery task inside the function which is passed to migrations.RunPython(). Even for testing this functionality, I don't have an existing data in our lower environment and the required migrations are already applied before even including this function. I don't want to mess with existing DB as everyone is using already. Can someone please confirm if I can actually run long running celery tasks when applying the migrations? in python manage.py migrate appname? Django: 1.11.15 … -

This simply gives a blank output. 1.How do I print the values? 2.If the filter returns multiple rows, how do I print them individually in the template? -
