Como criar um campo personalizado de modelo no django que funcione como uma lista que armazena objetos de uma outra tabela? [closed]
Estou fazendo um crud onde eu tenho uma tabela de empréstimo de livros, e preciso de um campo da model do django que funcione como um array ou lista de objetos para armazenar 1 ou mais livros que serão emprestados. Obs: Livro também é um tabela armazenada no banco de dados. E também se for possível fazer isso utilizando os próprios relacionamentos foreignkey ou manytomanyfield fornecidos pelo Django, se puderem me dar alguns exemplos de como fazer isso. -
Difference between declaring and excluding models when using dumpdata?
I'm having serialization dependency errors when trying to use dumpdata (or tests!) and am trying to diagnose the source of the problem by dumping various combinations of models to see which ones throw errors. When I explicitly declare every model except for two, it works: python manage.py dumpdata app1.ActionItem app1.ActivityLog app1.Aim app1.Bank app1.BenchmarkCategory app1.BenchmarkValue app1.Benchmark app1.Citation app1.City app1.Client app1.ComplaintStage app1.ComplaintSubscription app1.Complaint app1.Contact app1.Country app1.DocumentCategory app1.Document app1.ExplanationCategory app1.Explanation app1.FAQ app1.GoalUpdate app1.Goal app1.Group app1.IAM app1.IFISupport app1.Investment app1.Issue app1.KeyDateCategory app1.KeyDate app1.KeyTerm app1.Language app1.NCP app1.NoteCategory app1.Note app1.OrgType app1.Organization app1.Outcome app1.Region app1.ResearchRequest app1.Sector app1.Source app1.SubGoal app1.SupportItem app1.Tag app1.Team app1.TimePeriod app1.UserProfile app1.Workplan app2 app3 app4 --natural-primary --natural-foreign --output='data_dump.json' -v=3 --indent=4 --traceback But when I try dumpdata by excluding those two models, it throws the same dependency error: python manage.py dumpdata -e=app1.project -e=app1.case --natural-primary --natural-foreign --output='complaint_dump.json' -v=3 --indent=4 --traceback RuntimeError: Can't resolve dependencies for app1.ActionItem, app1.ActivityLog, app2.AnnualEvaluation, app1.Case, app1.Citation, app2.Commitment, app1.Complaint, app1.ComplaintStage, app1.ComplaintSubscription, app1.Contact, app1.Document, app2.Feedback, app1.Goal, app2.Goal, app1.GoalUpdate, app1.Investment, app1.KeyDate, app1.Note, app3.OCR, app1.Project, app2.QuarterlyUpdate, app1.ResearchRequest, app1.Source, app1.SubGoal, app4.Subscription, app1.SupportItem, app3.Survey, app2.Tactic, app1.UserProfile, app1.Workplan in serialized app list. Note that even the excluded models are showing up in the error. Am I running the exclude incorrectly somehow? -
Django 2.2 - checking user permission (perms.blog.change_blogpost) not working
So I've been stuck on this for days, not kidding. I've looked at over 20 different websites, all about Django user permissions. I cannot get the code to work not matter what I do.

Accessing an api running in a docker host from a different docker host
I have two docker projects each with their own docker-compose.yml files. One project holds a django api with docker host for that, while the other project is for open edx which running on another docker host. If I try to access my django api from one of these docker containers of the second docker host using docker exec -it edx.devstack.studio curl http://localhost:8000/number/, I get an error curl: (7) Failed to connect to localhost port 8000: Connection refused. I'm by no means a docker expert so there's something I'm probably doing wrong. I tried adding all the docker services in both projects to the same network but it still failed, probably I'm doing it wrong. Any help will be much appreciated.

annotate: whether a given value exists in m2m field
I have a query that retrieve an object like this: { "id": 1, "tags": [1, 2, 3] } I want to check whether a given tag (say, 1) exists in the tags field of the object, and annotate the result of the check as a field of the object: { "id": 1, "tagged": true } This is what I came up with annotate( tagged=Exists( Articles.tag_set.through.objects.filter( article_id=OuterRef("pk"), tag_id=tag.id ) ) ) Since the relation tags is already loaded by the primary query, having a secondary query seems redundant to me. Is there an easier way to structure this query? Something close to the filter syntax tags__contains=tag. -

Read a Django UploadedFile into a pandas DataFrame
I am attempting to read a .csv file uploaded to Django into a DataFrame. I am following the instructions and the Django REST Framework page for uploading files. When I PUT a .csv file to a defined endpoint I end up with a Django UploadedFile object, in particular, a TemporaryUploadedFile. I am trying to read this object into a pandas Dataframe using read_csv, however, there is additional formatting around the temporary uploaded file. I am wondering how to read the original .csv file that was uploaded. According to the DRF docs, I have assigned: file_obj = request.data['file'] Inside of a Python debugging console, I see: ipdb> file_obj <TemporaryUploadedFile: foobar.csv (multipart/form-data; boundary=--------------------------044608164241682586561733)> Things I've tried so far. With the original file path, I can read it into pandas like this. dataframe = pd.read_csv(open("foobar.csv", "rb")) However, the original file has additional metadata added by Django during the upload process. ipdb> pd.read_csv(open(file_obj.temporary_file_path(), "rb")) *** pandas.errors.ParserError: Error tokenizing data. C error: Expected 1 fields in line 5, saw 32 If I try to use the UploadedFile.read() method, I run into the following issue. ipdb> dataframe = pd.read_csv(file_obj.read()) *** OSError: Expected file path name or file-like object, got <class 'bytes'> type Thanks! -

Django PostgreSQL existing database does not exist
I have a table tablename with schema sub in PostgreSQL that definitely exists--it has been created, it has had data added to it, and when I run SELECT * FROM sub.tablename in pgAdmin 4, it returns results without issue. When I try to then access that same table in my Django application, it produces error psycopg2.OperationalError: FATAL: database "main.sub.tablename" does not exist. I attempted making the table name sub.tablename and tablename but it still claims the table does not exist. I am the owner of sub and it is my credentials used to access the table. I have confirmed that the host name and the port are what they should be. I'm at a loss as to how to fix this since, as far as I can tell, this error only shows up when people haven't actually created the table yet or misspell something. Below is my relevant code blurb in settings.py where the table/database info appears. settings.py DATABASES = { 'default': { 'NAME': 'tablename', 'ENGINE': 'django.db.backends.postgresql', 'USER': 'username', 'PASSWORD': 'password', 'HOST': 'localhost', 'PORT': '1234', } } Traceback Traceback (most recent call last): File "/usr/local/lib/python3.7/site-packages/django/db/backends/base/base.py", line 216, in ensure_connection self.connect() File "/usr/local/lib/python3.7/site-packages/django/db/backends/base/base.py", line 194, in connect self.connection = self.get_new_connection(conn_params) File … -

Django Relations with Models
I try to figure a clever way out for my models. I have two models where i want the Legend to have 4 different skills(Skill Model), but I cant seem to get the fitting model relation for it class Skill(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4) title = models.CharField(max_length=100) description = models.CharField(max_length=300) image = models.ImageField(upload_to='skills/', blank=True, null=True) class Legend(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4) title = models.CharField(max_length=100) description = models.CharField(max_length=1000) image = models.ImageField(upload_to='legends/%Y/', blank=True, null=True) skill_1 = models.(Skill, on_delete=models.SET_NULL, null=True) skill_2 = models.OneToOneField(Skill, on_delete=models.SET_NULL, null=True) skill_3 = models.OneToOneField(Skill, on_delete=models.SET_NULL, null=True) skill_4 = models.OneToOneField(Skill, on_delete=models.SET_NULL, null=True) The problem is I cant rly make a OneToOneField because it want´s a related_name for each, which would make No sense here, since they are all skills and I dont want to call for the owner (Legend) of the skill in 4 different ways I also tried to make a legend field in the Skill model with a foreignkey on the Legend, but that didnt turned out how i wanted it to be. thanks for the help ^.^ -
Validate across nested serializers with django rest framework
If you were to have a nested serializer, but required a certain parameter in the parent depending on a value in the child, how could you enforce the logical requirement when necessary? For example: class ChildSerializer(serializers.ModelSerializer): foobar_attribute = serializers.ChoiceField( required=True, choices=foobar_choices, ) class ParentSerializer(serializers.ModelSerializer): child = ChildSerializer(required=True) optional_attribute = serializers.CharField( required=False, ) optional_attribute should be required only when foobar_attribute is a certain choice, but optional for all else. Throwing a validate function on ParentSerializer or ChildSerializer only exposes attributes for that serializer, and none else. How can I perform validation across nested serializers without creating rows ( as would occur if validation was performed in perform_create )? -
Deploy Machine learning Models with Django
I'm following Piotr Płoński's guide on Deploying ML models with Django Currently where I am in the Guide: https://www.deploymachinelearning.com/#algorithms-registry (Just above this section) I got this point but my server doesn't want to run when I type in python manage.py test apps.ml.tests as the guide says in the guide. The error of that I am getting OSError: [WinError 123] The filename, directory name, or volume label syntax is incorrect: '<frozen importlib._bootstrap> Have any of you had this error before? and what's the fix? Some searches I did say its a path or URL error but I don't see any URLs or paths in the code (Might be mistaken) I saw that Piotr Płoński is on Stackoverflow @pplonski wonder if I can hear from the man himself :D If anyone could assist or point me in the right direction that would be appreciated.

Where is this mystery cache in Apache?
I have a django app running in a virtualenv on Windows 10 WSL1 (Ubuntu). The python version is 3.6.8. When using the django development web server, python manage.py runserver, everything is fine. I access that with http://localhost:8000/<my app name>/ But when using apache2, version 2.4.29, months-old javascript code shows up in the browser debugger in a VMxxx file, though I haven't yet found an eval() that's generating that. Also, old server-side code shows up: an old javascript error that resulted from the django python code sending the wrong content type - a bug that was fixed a couple of weeks ago. I'm accessing apache2 with http://localhost/<my app name>/ I disabled mod_cache: a2dismod cache Module cache already disabled. Also ran htcacheclean -r -l1k and manually looked at the page cache directory, which was empty. I clear the Chrome cache on every page load, but also get the same errors when using a different browser (Firefox) that wasn't even installed when this old code that's showing up was written. I put in a HTTP header to request no caching: <meta http-equiv="Cache-Control" content="no-store" /> The closest thing to a cache that I have configured in Django settings is SESSION_ENGINE = 'django.contrib.sessions.backends.cached_db', no CACHES … -
Model to Insert multiple values for the same field?
The goal is to put multiple status_code and event_code for 1 instruction. So 1 instruction can be associated with one or multiple scrap_code or event_code. But a single scrap_code or event_code cannot have more than 1 instruction. class Instruction(models.Model): name = models.CharField(max_length=100) I have made 2 separate models for scrap_code and event_code class ScrapCodeInstruction(models.Model): scrap_code = models.IntegerField() instruction = models.ForeignKey(Instruction) class EventCodeInstruction(models.Model): event_code = models.IntegerField() instruction = models.ForeignKey(Instruction) I need to register it in admin in the way that for 1 instruction there can be multiple scrap_code or event_code. Also scrap_code(s) and event_code(s) can share the same Instruction. I can use InlineModelAdmin like TabularInline or StackedInline in admin. But it would be great if the values come as comma separated rather than Tabular of Stacked. How can I make it as comma separated in admin?(2nd way to have multiple fields together) -

Consistent Wagtail menus showing parents, children and siblings
I have a simple Wagtail site made of several pages of type HomePage I want use Wagtails in-built menu system for all pages created from the HomePage model and home_page.html template. All the pages have Show in menus: selected.

Question: how do I get the menu show the root HomePage and also the child pages even when I am on a sibling, parent or child page? Any help greatly received. -
Endpoints sharing part of an URL
I'm currently building an API and I want to have two viewsets. One related to my User model, and one single route to verify a User email (you POST the currently-valid token to the endpoint). So it looks like this: UserViewSet, which allows POST, GET, PUT, PATCH, DELETE VerifyUserViewSet, which only allows POST In my router, here's my config: router = routers.DefaultRouter() router.register("users", UserViewSet, "users") router.register("users/verify", VerifyUserViewset, "users/verify") My problem is as follows: "users/verify" allows a GET request (when it shouldn't) because it is targeting the "users" endpoint with "request" as the user id. If I change the order in my router, then "users" only accept POST because the endpoints targets "users/verify". This seems to be happening because they share the same url part "users". Is there a way to bypass this behavior so that they don't overlap without changing the endpoints url? Thanks -
