Porting and existing nested set hierarchy
I have a nested set category table developed with the PHP ORM Doctrine and I would like to port it to a Django app. I started porting it to django-treebeard, but I am having difficulties and I am not sure it can work. The original table had the needed fields lft, rgt and depth, so I added the tree_id field. I also had a foreign key to Accounts with one tree/account. Thus the table hold multiple independent trees that are not under a common root, with the lft and depth columns starting at 1 for each tree. So basically one nested set for each account in the table. I can add nodes to a tree just fine, but when I call the get_last_child method, I get nodes from other accounts. Does anyone know if there is a way to use treebeard, mptt or any other package without having to restructure the trees? -

Django REST Framework, setting up Django Storages/S3 Boto to store some media files to the bucket, and some to local storage
I've setup Django Storages/S3 Boto to save user-uploaded files to the s3 bucket, with the settings bellow: # AWS Bucket access keys AWS_ACCESS_KEY_ID = 'id' AWS_SECRET_ACCESS_KEY = 'key' # AWS Bucket config stuff DEFAULT_FILE_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage' AWS_STORAGE_BUCKET_NAME = 'bucketname' AWS_S3_REGION_NAME = 'us-east-1' AWS_S3_CUSTOM_DOMAIN = f'{AWS_STORAGE_BUCKET_NAME}.s3.amazonaws.com/' AWS_S3_OBJECT_PARAMETERS = {'CacheControl': 'max-age=86400'} # Media file location MEDIA_URL = f'https://{AWS_S3_CUSTOM_DOMAIN}/' How would i modify the storage settings/configuration so that i can save some user uploaded files to this S3 bucket, while saving some others to the local file system? Currently, my FileField looks like this: class File(models.Model): created_at = models.DateTimeField(auto_now_add=True) email = models.EmailField(default='email@email.com') file = models.FileField(upload_to=upload_path) def __str__(self): return self.email + '-' + self.file.name my "upload_path" looks like this: def upload_path(instance, filename): return instance.email + '/' + filename -

How to plug the reponse of a django view GET request into the same view as a POST request during testing?
I have a Django function-based form view that initializes a form with default data on a GET request, and saves the model object on a POST request: def copy(request, ann_id): new_ann = get_object_or_404(Announcement, pk=ann_id) new_ann.pk = None # autogen a new primary key (quest_id by default) new_ann.title = "Copy of " + new_ann.title new_ann.draft = True new_ann.datetime_released = new_ann.datetime_released + timedelta(days=7) form = AnnouncementForm(request.POST or None, instance=new_ann) if form.is_valid(): new_announcement = form.save(commit=False) new_announcement.author = request.user new_announcement.datetime_created = timezone.now() new_announcement.save() form.save() return redirect(new_announcement) context = { "title": "", "heading": "Copy an Announcement", "form": form, "submit_btn_value": "Create", } return render(request, "announcements/form.html", context) I can't figure out how to test the form.is_valid() branch when the form is posted, without manually providing the form data to self.client.post(url, form_data) in my view. What I want to actually test is that the result of the get provides valid default data for the form that can then be submitted via post request. But I can't figure out how to change the repsonses, so that the form data resulting form the get request is then fed into the form data provided to the post request. EDIT I found the location of the form in the get response, but … -
DJONGO - Querying Array fields with DateField filter
I have a model called GOALS it has a field of type "ArrayModelField". This field is a list of another model called GOAL, that has a Date type field, as shown below: from djongo import models class Goal(models.Model): date = models.DateField() daily_value = models.FloatField() hourly_values = models.ListField(default=[]) class Goals(models.Model): name = models.TextField(primary_key=True, null=False, blank=False) goals = models.ArrayModelField(model_container=Goal, default=[]) eu = models.TextField(null=True, blank=True) I am trying to filter my results by the fields in the inner model (GOAL), and I know it is possible because there are some examples in Djongo's documentation showing how to do it: class Blog(models.Model): name = models.CharField(max_length=100) tagline = models.TextField() class Author(models.Model): name = models.CharField(max_length=200) email = models.EmailField() class Entry(models.Model): blog = models.EmbeddedField( model_container=Blog, model_form_class=BlogForm ) headline = models.CharField(max_length=255) authors = models.ArrayField( model_container=Author, model_form_class=AuthorForm ) entries = Entry.objects.filter(authors={'name': 'Paul'}) Or even looking at an specific array position, like so: entries = Entry.objects.filter(authors={'2.name': 'Paul'}) But in my case, I want to go a little further, I want to filter by a specific YEAR in my DateField. In DJANGO would be something like this: Goals.objects.filter(date__year='2011') I wonder... is there something similar in DJONGO? Maybe something in these lines?

Django Model/Manager Dependency
When using a Custom Model Manager the way it is shown in the documentation and examples that I have found, the Custom Managers are placed in the same source file as the Model. My models.py file has a base class with four sub-classes and the base class has several static methods to provide some common queries. I will need to add quite a few custom queries. I would prefer to put these in a Custom Model Manager that is a Base class for each of the subclasses Model Managers. I would also like to be able to separate the Model Managers into a separate source file called managers.py to make the code less messy. The problem is that there is a cyclic dependency between the Models and Managers. Is there a way to set the Manager to the "objects" variable by name instead of the actual Model Manager class? Or perhaps some other way to be able to put the code into the two separate files? models.py class MyBaseModelClass(models.Model): (abstract) class class SubclassA(MyBaseModelClass): objects = SubclassAManager() class class SubclassB(MyBaseModelClass): objects = SubclassBManager() class class SubclassC(MyBaseModelClass): objects = SubclassCManager() class class SubclassD(MyBaseModelClass): objects = SubclassDManager() managers.py class MyCustomBaseManager(models.Manager): # Does custom … -

Django Ajax form not submitting and page freezes

Django Queryset in template

remove orphaned file from a model
I have the following model: class Class(models.Model): title = models.CharField(max_length = 60) video = models.FileField( upload_to = class_files_custom_upload, validators = [ FileExtensionValidator(['mp4', 'webm', 'mpg', 'mpeg', 'ogv']), ] ) section = models.ForeignKey(Section, on_delete = models.CASCADE) created = models.DateTimeField(auto_now_add = True) class Meta: verbose_name = 'clase' verbose_name_plural = 'clases' ordering = ['created'] def __str__(self): return self.title I create an instance of this model, but if I update the video field with another file of any instance, the previous saved file is orphaned and the file takes up space and I want to avoid it, deleting the file. To do this I customize the file load, putting a callable in the upload_to: def class_files_custom_upload(instance, filename): try: old_instance = Class.objects.get(id = instance.id) old_instance.video.delete() except Class.DoesNotExist: pass return os.path.join('courses/videos', generate_secure_filename(filename)) In this way I achieve my goal. But I have several models that save multimedia files, and for each one I have to customize the file load, practically doing a function almost equal to class_files_custom_upload, and the code repeats and this is not optimal at all. I tried to create a reusable function that meets the goal of the class_files_custom_upload function, in various fields like ImageField and FileField, but I can't do it since the … -

Django TestCase and Transactions
I am running into a weird issue while writing unit tests that I think is related to this from the django docs - Django's TestCase class wraps each test in a transaction and rolls back that transaction after each test, in order to provide test isolation. This means that no transaction is ever actually committed, thus your on_commit() callbacks will never be run. My issue is occuring when working with update_fields in save(). Some pseudo code for example. object.is_processing = timezone.now() object.save(update_fields=['updated', 'is_processing']) try: with transaction.atomic(): # do stuff object.other_field = value object.save() finally: object.is_processing = None object.save(update_fields=['updated', 'is_processing']) Now when I run tests, it tries to create the object twice. Why? I think it is because this is all in a transaction, so the object is never actually committed to the database. When I call save with update_fields the pk is excluded, so it looks at it like a new object, and tries creating it twice. If I do the following, it works. object.is_processing = timezone.now() object.save() try: with transaction.atomic(): # do stuff object.other_field = value object.save() finally: object.is_processing = None object.save() What I am trying to figure out is how to test this without changing the production code … -
