What is the standard oAuth/OIDC flow for creating/logging in a user into client server?
Problem: I want to use information from ID Token (userinfo) to login or create a user for my (app) client server. I am unsure of the standard way to approach this problem as i'm new to oauth and OIDC. My problem lies on the standard flow for creating a session token for my user to access my client server protected routes. I have successfully logged in with my gmail which includes both my google access token and OIDC ID Token. I have also set up a PostgreSQL data base and user models using django. I have also verified or created a user based on my ID Token information. I can use data (email, sub, ect) to verify/create user in client database, but what is the standard approach to creating a session token to acces my client server endpoints? If I create a entirely seperate client server session token, do I use any information from the ID Token? Used this video and auth0 django quickstart tutorial for django integration below. https://www.youtube.com/watch?v=996OiexHze0 https://github.com/auth0-samples/auth0-django-web-app/tree/master -
Django, html page I cannot fix layout problem
I am trying to make layout in my html form page and I have 2 problem. 1- As you can see in screenshot number 1 below, I wanted to add a button next to the type field, but the button appears under the type field. No matter what I did, I couldn't bring side by side. 2-When I connect a modal to the button I added, it disrupts all the page layouts after it. You can find it in screenshot number 2. Here is my html code: {% extends 'base.html' %} {% load widget_tweaks %} {% block content %} <div class="container-fluid px-5 mt-5"> <div class="card card-body"> <div class="container-fluid px-5 mt-5"> <h1>Record Detail Page</h1> </div> <div class="container-fluid px-5 mt-5"> <form class="row g-4" method="post"> {% csrf_token %} <div class="col-md-3"> <label for="inputDirection" class="form-label">Direction</label> {% render_field form.Direction class="form-control"%} </div> <div class="col-md-3"> <label for="inputType" class="form-label">Type</label> {% render_field form.Type placeholder="Type" class="form-control"%} <!-- Zoom Button Start--> <div class="input-group"> <a href="" class="text-decoration-none" data-bs-toggle="modal" data-bs-target="#typeRecordModal"> <svg xmlns="http://www.w3.org/2000/svg" width="16" height="16" fill="currentColor" class="bi bi-arrow-up-right-square" viewBox="0 0 16 16"> <path fill-rule="evenodd" d="M15 2a1 1 0 0 0-1-1H2a1 1 0 0 0-1 1v12a1 1 0 0 0 1 1h12a1 1 0 0 0 1-1zM0 2a2 2 0 0 1 2-2h12a2 2 0 0 … -
sklearn LinearRegression predict returns different results for full dataframe vs iteration over rows
My model class uses StandardScaler and Linear Regression def train(self, data): features = data[self.feature_names].values target = data[self.target_name].values self.scaler = StandardScaler() scaled_features = self.scaler.fit_transform(features) self.regressor = LinearRegression() self.regressor.fit(scaled_features, target) Now I have defined two functions which should either handle a single entry (pandas Series) or multiple entries (pandas DataFrame) def predict_one(self, single_data): """ returns a float """ features = single_data[self.feature_names].values.reshape(1, -1) scaled_features = self.scaler.transform(features) return self.regressor.predict(scaled_features)[0,0] def predict_many(self, multi_data): """ returns a 1D numpy array of floats """ features = multi_data[self.feature_names].values scaled_features = self.scaler.transform(features) return self.regressor.predict(scaled_features).flatten() Then I check whether if I iterate through .iterrows() and save predict_one() results in a list, I get the same results as for predict_many(). And I don't. I have now followed the rabbit hole - it is not the StandardScaler, rather if I just call self.regressor either on full dataset or row by row I get slightly different results: array([[3.10862447e-15], [3.10862447e-15], [3.10862447e-15], [3.10862447e-15] ... vs [array([[3.55271368e-15]]), array([[3.55271368e-15]]), array([[3.55271368e-15]]), array([[3.55271368e-15]]), I just wonder why, even if it is E-15 scale. -
I am trying to deploy a django project on EC2 but can't clone the project repository
I am trying to deploy my django project on an EC2 instance, but when I run git clone, it shows following error: ubuntu@ip-172-31-45-92:~$ git clone git@github.com:Animesh0764/Codex-CP-Analyzer.git Cloning into 'Codex-CP-Analyzer'... git@github.com: Permission denied (publickey). fatal: Could not read from remote repository.

Django + Javascript, SCSS proper workflow

How to create an encrypted password with mixer for Django testing?
I'm trying to write a functional test for my Django project where I also want to test the login. For this I want to use mixer to create a user and then log in with the access data. Unfortunately this does not work. Mixer creates a user, but no real password or no encrypted password. As a result, I cannot log in to the test. If I use Django's own function make_password and create the password with it and the user with mixer, then it works. Is there nothing from mixer itself? Code not working # enter correct credentials reg_user = mixer.blend(User) driver.find_element(By.ID, "login-username").clear() driver.find_element(By.ID, "login-username").send_keys(reg_user.username) driver.find_element(By.ID, "login-pwd").clear() driver.find_element(By.ID, "login-pwd").send_keys(reg_user.password) driver.find_element(By.XPATH, "//button[@type='submit']").click() driver.implicitly_wait(5) # assert redirected to home assert driver.current_url == f"{base_url}/" Working Code from django.contrib.auth.hashers import make_password # enter correct credentials password = make_password("test_3") reg_user = mixer.blend(User, password=password) driver.find_element(By.ID, "login-username").clear() driver.find_element(By.ID, "login-username").send_keys(reg_user.username) driver.find_element(By.ID, "login-pwd").clear() driver.find_element(By.ID, "login-pwd").send_keys("test_3") driver.find_element(By.XPATH, "//button[@type='submit']").click() driver.implicitly_wait(5) # assert redirected to home assert driver.current_url == f"{base_url}/" -

Can the AUROC of sufficiently cross-validated models be below 0.5?
I predict binary outcome using a LogisticRegressor using a Pandas data frame containing 151 features2 of 111 samples. Labels are somewhat imbalanced (42/69, 62.1% majority class). I do this for 4 data_frames (same labels, different data). Results of the code below make sense for all time points but one. For one time point, I have been struck with results I cannot explain: Using Leave-One-Out cross-validation on 111 samples, I get AUROCs substantially below 0.5 (see figure 2) This should no be possible with sufficient validation & a correct implementation. Chance of this is 1.3e-6. I cannot find the culprit. I investigated several probable causes: the code (1, 4), the labels (2), the data (5), chance (3, 6) and the number of features (7). Minimal SKLearn implementation1 This implementation is much like what I used, but I had to simplify the data to stay within the Stackoverflow Character limit, so results can somewhat differ. import pandas as pd from sklearn.linear_model import LogisticRegression from sklearn.model_selection import cross_val_predict, LeaveOneOut, cross_val_score, RepeatedKFold from sklearn.metrics import roc_auc_score, accuracy_score, RocCurveDisplay from sklearn.pipeline import make_pipeline from sklearn.preprocessing import StandardScaler from matplotlib import pyplot as plt X = pd.DataFrame([[142, 157, 173, 188, 201, 211, 218, 223, 224, 225, … -
Django Caching Token based Authentication

Why this API request is not working properly

Storing user-specific data during a Django session
I have a question about database organization in Django. Let this be, for example, some simple browser game based on the parameters of the characters. The user creates his own The Fellowship of the Ring from standard characters that have certain initial parameters. At this point, the characters for each user are identical and can be taken from a single table. But during the session, the parameters of each character will change. Between sessions, character data can be stored in JSON. But during the game, unpacking and repacking JSON into the database every time does not sound like a very good idea(a lot of calculations on the server side and a lot of changes to the template on the client side). What's the best way to store user-specific data during a session? P.S. Of course, I know about Django Sessions, but I’m not sure that this is suitable for the described task -

Hosting Django-Streamlit Integrated Web Apps
I've developed a web application using Django that handles user authentication, including signup and login processes. Upon successful signup, the intention is to redirect the user seamlessly to a separate Streamlit application. Detailed Overview: Application Structure: The web app comprises two distinct components: a Django-based authentication system and a Streamlit-based dashboard or app. Signup and Redirection: After a user successfully signs up through Django, the objective is to automatically redirect them to the Streamlit app without requiring an additional login. Deployment Query: My challenge lies in understanding the deployment process for this integrated structure. I'm seeking guidance on how to host both Django and Streamlit apps in a manner that allows them to interact seamlessly after the signup process. Specific Queries: Hosting Strategy: Which platforms or hosting services would be suitable for deploying these two applications? I'm relatively new to deployment and recently developed a web app using Django for user authentication (signup/login). Upon successful signup, I aimed to redirect users seamlessly to a separate Streamlit app. -

I added part of my code related to my question please feel free for more information. thanks in advance. views.py def post_delete(request,pk): post = get_object_or_404(Post,pk=pk) if request.method == 'POST': post.delete() return redirect('blog_list') return render(request,"blog/post_delete.html",{"post":post}) urls.py urlpatterns=[ path("",views.blog_list,name="blog_list"), path("<int:pk>/",views.post_details,name="post_detail"), path("create/",views.create_new_post,name="post_create"), path('<int:pk>/update/', views.post_update ,name='post_update'), path('<int:pk>/delete/', views.post_delete , name='post_delete'), ] models.py class Post(models.Model): STATUS_CHOICES=( ('pub','published'), ('drf','draft'), ) title=models.CharField(max_length=100) text=models.TextField() status=models.CharField(max_length=3,choices=STATUS_CHOICES) created_datetime=models.DateTimeField(auto_now_add=True) modified_datetime=models.DateTimeField(auto_now=True) author=models.ForeignKey(User, on_delete=models.CASCADE) test.py class TestBlogPost(TestCase): @classmethod def setUpTestData(cls): cls.user=User.objects.create(username="user1") cls.post1=Post.objects.create( title="post1", text="this is post1", status=Post.STATUS_CHOICES[1][0], author=cls.user ) def test_delete_post_view_url(self): response = self.client.post(reverse("post_delete",args=[self.post1.id])) self.assertEqual(response.status_code,302) ** self.assertNotContains(response, self.post1.title) ** **error I got: AssertionError: 302 != 200 : Couldn't retrieve content: Response code was 302 (expected 200) ** -
Django - How to prevent Custom Field Validator from executing unless the field has changed?
I have a custom validator that checks that the size of the uploaded gallery image is not too big. This validator runs every time the model is saved no matter if the field has changed or not. This usually wouldn't be a big issue. The problem is that I have an admin panel inline, and any time I save the parent model "Profile" the validation inside of all the children "GalleryImages" gets executed. The validation of 50 images takes a long time since it needs to load all images and check for the resolution. How can I configure this validator to only run if the field value has been updated? # models.py @deconstructible class ImageValidator(object): """ Checks that image specs are valid """ def call(self, value): # Some code to check for max size, width and height if too_big: ValidationError('Image is too big') class Profile(Model): user = models.ForeignKey(User) class GalleryImage(Model): profile = models.ForeignKey(Profile) image = models.ImageField(validators=[ImageValidator]) # admin.py class GalleryImageInline(admin.TabularInline): model = GalleryImage @admin.register(Profile) class ProfileAdmin(ModelAdmin): inlines = [GalleryImage] -
Need Help Troubleshooting Django Registration Error
I'm encountering an issue with the registration functionality in my Django project. When I attempt to register a new user, I receive a generic error message, "There was an error, please try again," instead of a successful registration confirmation. Here is my project view.py def login_user(request): if request.method == "POST": username = request.POST['username'] password = request.POST['password'] user = authenticate(request, username=username, password=password) if user is not None: login(request, user) messages.success(request, ("You Have Been Logged In!")) return redirect('home') else: messages.success(request, ("There was an error, please try again")) return redirect('login') else: return render(request, 'login.html', {}) def logout_user(request): logout(request) messages.success(request, ("You have been logged out")) return redirect('home') pages navbar.html {% if user.is_authenticated %} <li class="nav-item"><a class="nav-link" href="{% url 'logout' %}">Logout</a></li> {% else %} <li class="nav-item"><a class="nav-link" href="{% url 'login' %}">Login</a></li> {% endif %} pages urls.py from django.urls import path from . import views urlpatterns = [ path('', views.home, name='home'), path('about/', views.about, name='about'), path('login/', views.login_user, name='login'), path('logout/', views.logout_user, name='logout'), ]
