Is there a third-party authentication system for Django?
We are trying to integrate a Django application with an OpenID Connect (OIDC) provider as a Relying Party. The provider isn't a major vendor, and thus doesn't have custom-built packages, so we are leveraging Authlib. This works, but I'm stressed about the amount of custom code we are having to put in to manage the session and redirects and whatnot. I have experience in the Ruby and Node.js worlds, and those communities have the general-purpose authentication tools OmniAuth and Passport, respectively. Is there an equivalent for Django? Closest I've found is mozilla-django-oidc, which I may try — curious if there are others I'm missing. Thanks! -
Bulk import with mptt and Django
I have the following code to take data from a very large csv, import it into a Django model and convert it into nested categories (mptt model). with open(path, "rt") as f: reader = csv.reader(f, dialect="excel") next(reader) for row in reader: if int(row[2]) == 0: obj = Category( cat_id=int(row[0]), cat_name=row[1], cat_parent_id=int(row[2]), cat_level=int(row[3]), cat_link=row[4], ) obj.save() else: parent_id = Category.objects.get(cat_id=int(row[2])) obj = Category( cat_id=int(row[0]), cat_name=row[1], cat_parent_id=int(row[2]), cat_level=int(row[3]), cat_link=row[4], parent=parent_id, ) obj.save() It takes over an hour to run this import. Is there a more efficient way to do this? I tried a bulk_create list comprehension, but found I need parent_id = Category.objects.get(cat_id=int(row[2])) to get mptt to nest correctly. Also, I think I have to save each insertion for mptt to properly update. I'm pretty sure the parent_id query is making the operation so slow as it has to query the database for every row in the CSV (over 27k rows). The upside is this operation will only need to be done sporadically, but this dataset isn't so large that it should take over an hour to run. -
How do I add cropperjs to my django project
I am working on a django project that requires adding a profile picture and that works; but where the problem comes in is that when someone uploads a picture that is quite long or quite wide, the profile image display would look weird. I tried initializing basic cropperjs by adding this to my base.html <link rel="stylesheet" href="{% static 'cropperjs/dist/cropper.min.css' %}"> <script type="module" src="{% static 'cropperjs/dist/cropper.min.js' %}"> and i just wanted to follow the docs and i kept my edit-profile.html {% block content %} <div class="image-box"> <img src="{{ request.user.userprofile.profile_image.url }}" id="image" width="300px"> </div> {% endblock %} and my edit-profile.js console.log('Hello there') var $image = $('#image'); $image.cropper({ aspectRatio: 16 / 9, crop: function(event) { console.log(event.detail.x); console.log(event.detail.y); console.log(event.detail.width); console.log(event.detail.height); console.log(event.detail.rotate); console.log(event.detail.scaleX); console.log(event.detail.scaleY); } }); var cropper = $image.data('cropper'); but then when i runserver and i inspect the page, i see the error edit_profile.js:3 Uncaught ReferenceError: $ is not defined at edit_profile.js:3:14 so i tried creating a normal html file and linked it with a javascript file an then tried to initialize cropper. index.html <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1"> <link rel="stylesheet" type="text/css" href="forum/static/cropperjs/dist/cropper.css"> <meta http-equiv="Access-Control-Allow-Origin" content="*"/> <title>Test site</title> </head> <body> <div class="image-box"> <img src="yor.png" id="image" width="300px"> </div> <script type="text/javascript" … -
How to get all manytomany objects in a queryset of objects
I have a model Department which has Roles which Users are linked to. I know the user, but need to get the user.role.department_set.all() (all departments the user's role belong to) and then get all the roles in each of those departments. Models: class User(AbtractUser): role = models.ForeignKey(Role) class Role(models.Model): name = models.CharField() class Department(models.Model): name = models.CharField() roles = models.ManyToManyField() How can I get all the departments which contains the user's role, then get the roles of all those departments? I am doing something like this currently but it is a very expensive lookup: def get_departments(self): """Returns a list of departments the user is in.""" return self.role.department_set.all() def get_users_departments_roles(self): """Returns all the roles of all the departments the user is in.""" departments = self.get_departments() roles = Role.objects.none() for department in departments.iterator(): for role in department.roles.all(): roles |= Role.objects.filter(name=role.name) return roles Side question: After typing all this out, would it be better to just add the a department field to each user? My concern is that if a role changes, I will also have to change the department at the same time and it will add complexity. -

VS Code Auto Import Not Working Dockized Django Application
I have set up a Django Application on a Docker container locally. It runs and can be accessed on the browser on port 8000. However the issue is when I opened the Django Dockerized App in VS Code and tried to write viewsets, serializers and for that I expect VS Code should auto-import them from Django/DRF libraries path, but VS Code neither hints and nor auto-import any of the Django/DRF/Django_Model_Utils. I have tried all the options on this thread but the auto-import doesn't work for dockerized django app when container is opened in VS Code. Even I am able to manually import the Django/DRF modules classes and when ctrl + click, it bring me to the specified class.

How do you pass the value of user_type (in CustomUser model) passed to a model form?
I have gone through many Q&As in SO and tried out various solutions. But I'm not sure whether the issue is with the form (CustomUserForm or StaffCreateForm--neither solves this problem), the view, or the way the user_type is set up. Any pointer is greatly appreciated. The CustomUser model lists 3 user_types. The form displays a dropdown menu with the 3 choices. Regardless of my choice, I get an error: Select a valid choice. 2 is not one of the available choices.

Query MongoDB to fetch a nested array with skip/limit by nested object key range in Django using pymongo
I am learning Django with pymongo. I have a MongoDB collection where I am storing some words and their year-wise occurrences in some books. The documents are stored in MongoDB in the following format: { "_id":{ "$oid":"625c51eec27c99b793074501" }, "word":"entropy", "occurrence":13, "year":{ "1942":[ { "book":{ "$oid":"625c51eec27c99b7930744f9" }, "number":8, "sentence":[ 1, 288, 322, 1237, 2570, 2585, 2617, 2634 ] } ], "1947":[ { "book":{ "$oid":"625c5280c27c99b793077042" }, "number":5, "sentence":[ 377, 2108, 2771, 3467, 3502 ] } ] } } Now I want to get the list of the sentences with skip and limit (and the respective book id) queried by _id and for specific year range. For example, I want to fetch an array where each row will be a dictionary containing 'year', 'book' and 'sentence'. The array will be queried by the _id and year range. A skip and limit will be applied on the sentence list Is this a possible task using Django and pymongo? If yes, what is the fastest method? So far I have done this: search= {'$and': [{"_id": word_id_obj, "year.1942": {"$exists": 1}}]} datalist= [] word_docs= wordcollec.find(search, {'year': 1, '_id': 0}).skip(1).limit(5) sentlist['recordsFiltered']+= wordcollec.count_documents(search) for b in word_docs: year_data= b['year'][1942] for by in year_data: i= i+1 this_word= {'serial': i, 'year': … -
Django filter objects by Many-To-Many field intersection
Hello, Can some good person give me advice on how to get a queryset of ordered objects by intersecting a many-to-many field with a given one object's many-to-many field? For example I have: class Video(models.Model): tags = models.ManyToManyField(Tag, blank=True) ... class Tag(models.Model): name = models.CharField(max_length=64) ... I select one Video object and would like to have first ten objects that have most similar tags set to show like related videos. Thanks in advance!
