Django REST serializer error
I'm defining model serializers to POST a task instance in Django REST. My models are: class Task(models.Model): id = models.AutoField(primary_key=True) name = models.CharField(blank=True, max_length=100) description = models.CharField(blank=True, max_length=300) class Vector(models.Model): id = models.AutoField(primary_key=True) name = models.CharField() class CalculateVector(models.Model): """ Added 1:M relation between Vector and CalculateVector. """ id = models.AutoField(primary_key=True) task_id = models.ForeignKey(Task, related_name='calculate_vectors', on_delete=models.CASCADE) method = models.CharField() vector = models.ForeignKey(Vector, models.SET_NULL, related_name='vector') so each CalculateVector instance has info about only one Vector model instance, but Vector model can contain several CalculateVector instances. and my serializers are: class VectorSerializer(serializers.ModelSerializer): id = serializers.IntegerField() class Meta: model = Vector fields = ( 'id', 'name' ) class CalculateVectorSerializer(serializers.ModelSerializer): vector = VectorSerializer() class Meta: model = CalculateVector fields = ( 'id', 'method', 'vector' ) class CreateTaskSerializer(serializers.ModelSerializer): calculate_vectors = CalculateVectorSerializer() class Meta: model = Task fields = ( 'id', 'name', 'description', 'calculate_vectors' ) def create(self, validated_data): calculate_vector_data = validated_data.pop('calculate_vectors') instance = Task.objects.create(**validated_data) vector = Vector.objects.get(id=calculate_vector_data.get('vector')['id']) CalculateVector.objects.update_or_create( task_id=instance, method=calculate_vector_data['method'], vector=vector, ) return instance when tried to query this serializer I received an error using: >>> data = {'name':'test task','description':'description','calculate_vectors':{'vector':{'id':1,'name':'calc1'},'method':'method1'}} >>> serializer = CreateTaskSerializer(data=data) >>> serializer.is_valid() >>> serializer.save() >>> serializer.data AttributeError: Got AttributeError when attempting to get a value for field `vector` on serializer `CalculateVectorSerializer`.

Django diffrenet results from AND operation and sequential filter

Efficient way to scrape images from website in Django/Python
First I guess I should say I am still a bit of a Django/Python noob. I am in the midst of a project that allows users to enter a URL, the site scrapes the content from that page and returns images over a certain size and the page title tag so the user can then pick which image they want to use on their profile. A pretty standard scenario I assume. I have this working by using Selenium (headless Chrome browser) to grab the destination page content, some python to determine the file size and then my Django view spits it all out into a template. I then have it coded in such a way that the image the user selects will be downloaded and stored locally. However I seriously doubt the scalability of this, its currently just running locally and I am very concerned about how this would cope if there were lots of users all running at the same time. I am firing up that headless chrome browser every time a request is made which doesn't sound efficient, I am having to download the image to determine it's size so I can decide whether it's large enough. One … -
Generate thumbnail for inmemory uploaded video file
The client app uploaded a video file and i need to generate a thumbnail and dump it to AWS s3 and return the client the link to the thumbnail. I searched around and found ffmpeg fit for the purpose. The following was the code i could come up with: from ffmpy import FFmpeg import tempfile def generate_thumbnails(file_name): output_file = tempfile.NamedTemporaryFile(suffix='.jpg', delete=False, prefix=file_name) output_file_path = output_file.name try: # generate the thumbnail using the first frame of the video ff = FFmpeg(inputs={file_name: None}, outputs={output_file_path: ['-ss', '00:00:1', '-vframes', '1']}) ff.run() # upload generated thumbnail to s3 logic # return uploaded s3 path except: error = traceback.format_exc() write_error_log(error) finally: os.remove(output_file_path) return '' I was using django and was greeted with permission error for the above. I found out later than ffmpeg requires the file to be on the disk and doesn't just take into account the InMemory uploaded file (I may be wrong as i assumed this). Is there a way to read in memory video file likes normal ones using ffmpeg or should i use StringIO and dump it onto a temp. file? I prefer to not have the above done as it is an overhead. Any alternative solution with a better benchmark … -

django reusable app: remove dependencies in migrations?
I am writing a reusable django app, for django-cms. It will provide some cms-plugins, and a plugin framework. I have created migrations for my plugins. I started it some time ago, and the first plugins and it's migrations were created using django-cms==3.4.something, and they reference in there migrations files a dependency like this: dependencies = [ ('cms', '0016_auto_20160608_1535'), ] Now I worked again on that project, on another computer, installing django-cms==3.5.2 into my virtualenv. For a new plugin, this creates new migrations like this: dependencies = [ ('cms', '0020_old_tree_cleanup'), ] Obviously, this new migration cannot be used in an older cms project, using django-cms 3.4.x, as the needed dependency migration is not present. The question: Shall I add the 3.4.x migration dependency into my newly created migration? Or would it be better to completely remove those dependencies from my migrations (I doubt...)? -

JSON to POJO and/or POCO classes
I have a JSON as following: { "collaborators": [], "responsibilities": [ { "name": "Name" }, { "name": "Age" } ], "id": 12, "thing": "Reader" } My frontend is Angular and backend is Django. I am interested in converting this JSON into POJO and/or POCO classes. I see there are services online (http://json2csharp.com/) where one can paste JSON manually and get the POCO/POJO. I want to achieve this within my app. Is it convenient to do this on frontend side or backend side? Are there any libraries, APIs which could be of help? My quick google search wasn't much of a help. -
External file as Django File object
I have been trying to open external file (out of django's project root directory) and convert it to Django File object and then store to database, in FileField. I am receiving files through both GET and POST request. Files in POST request are passed as File Uploads, so they are directly received in django's internal directory, and can be converted to Django File object. But in case of GET, I just receive the file path: "/home/user/somefile.txt". File can be of any type, like text, image, csv, xls, etc. With python's file open, the file can be opened, even inside django, just the problem occurs when converting it to Django File, which says that the file is outside project root directory. I was thinking to open file, write it to internal directory with python basic file operation, then convert it to Django File object, but it may give encoding issues. There should be some better way than this. (Django v1.11, Python v3.6) -

Django create custome admin view with non database fields
I would like to create a custome admin view with fields with data that I fill manually, meaning that there's no database table behind.

Django unit testing: How should one test abstract models?
In my Django Project I have an app called 'core' which contains all my reusable model mixins / abstract models (behaviors.py), models (models.py), views (views.py) and helpers functions (utils.py): core/ __init__.py behaviors.py models.py utils.py views.py I know want to write tests for these files. For models, utils and views I just wrote unit tests like I'm used to. I'm now uncertain how I should test the abstract models contained in behaviors.py. For example I have this model mixin: import uuid as uuid_lib from django.db import models class UniversallyUniqueIdentifiable(models.Model): uuid = models.UUIDField( db_index=True, default=uuid_lib.uuid4, editable=False ) class Meta: abstract = True How can you test a abstract model? In one of the articles I used to learn about fat models, the author just tests the models in which he used the abstract models. But that feels not very DRY to me, since that would mean I would have to test the adding of the UUID in each model I use it in. Is there a better way to do it? -
