I have some problems using the command django-admin makemessages -l es I'm running it but the locale repertory still empty and and there is not .po files generated on my locale repertory . I add this following code on my setting.py file: LOCALE_PATHS = [ os.path.join(BASE_DIR, 'locale') ] And: MIDDLEWARE = [ 'corsheaders.middleware.CorsMiddleware', 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.locale.LocaleMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', ] I have gettext installed and I have created a repertory named locale on root of the project, I don't realy get the problem -
One Django app in a separate python package
Django==3.2.5 Please, have a look at the picture: INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'django.contrib.sites', 'clients', 'general', 'images', 'themes', 'omnibus', 'staticassets', 'categories', 'tags', 'articles', ] When I run this, I get: ModuleNotFoundError: No module named 'articles' It is predictable as Django doesn't know where to find the app. Then I tried like this: INSTALLED_APPS = [ 'dependencies.articles', ] No success. Here 'articles' is just an ordinary Django app like categouries or clients. But I'd like to move it to 'depencencies' package. Why? I'd like to organize the code structure like this for as personal preferences. If it is technically possible, please, help me cope with this problem. -

Django Rest Framework CSRF protection not working
I am developing an Angular application with Django Rest Framework and I want to configure CSRF protection. However, I can not seem to trigger CSRF violations when doing any POST request to the backend (for testing purposes). I currently do not use CSRF protection. My settings.py: MIDDLEWARE = [ 'corsheaders.middleware.CorsMiddleware', 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware' ] I configured my CORS headers such that: CORS_ALLOW_ALL_ORIGINS = True I do not use CSRF_TRUSTED_ORIGINS anywhere. Why is the CSRF protection not invoked? -

The names of the tables are auth_user, auth_user_group, auth_group. Now I need to establish a one-to-many relationship between the first two, the thing is I'm not quite sure how to do that because there are no modules. Any ideas? -

Is there a way to change the blank attribute on Django form fields to False by clicking a button?
I am building a review form that will post to a single model in my database. This form will have multiple sections, each with its own set of questions. I want the user to be able to complete a section and hit a submit button that will save the progress and redirect them to the next section. In essence I want to create an in progress status for the review with the idea that as all sections are finished the user can hit a complete button that will run my validation on the entire form. However, I do not want to allow posting information to the database that has not been cleaned. I've been thinking through this trying to work out what I need to do and believe the best bet would be to have a complete button on the last page that changes blank to False for the fields of the form. I believe this would allow me to fill out each form and post it to the database as all fields would start as optional but then for that specific model instance the click of the button at the end would institute a change making all fields required, … -

Creating HTML Modal for number of items in database
I am creating a donation application where users can view donations. If they want to learn more about a specific donation, they can click on the view button and an HTML overlay menu will come up. My problem is that I use a for loop to display every donation, and there is no specific number of donations, there can be infinite number of donations, and the view button only works for the first donation. How can I fix this so the view button can work for every donation?

CORS issue working with DJango Simple SSO
I'm using a fork of Django Simple SSO as an authentication mechanism on a Server. It works great while we use the "standard" way to log in on the server. This means, we just access to the /login path, log in, and then navigate across the restricted paths, etc. The problem comes when we want to connect to a 3rd server that also relays on SSO auth vía javascript/AJAX without direct access to /login path first. I've tried to use django-cors-headers but didn't get the expected result. I'm close to give up so any help is welcome. The problem When the browser is redirected to the Auth Server in order to verify that the browser is logged with a valid user, the cookie header is not transferred. (See the diagram on button for further details on how Simple SSO works) The headers set by the auth-server on the preflight request are the following: Access-Control-Allow-Credentials: true Access-Control-Allow-Headers: accept-encoding, accept, authorization, cookie, content-type, dnt, origin, user-agent, x-csrftoken, x-grafana-org-id, x-dashboard-id, x-panel-id, x-requested-with Access-Control-Allow-Methods: DELETE, GET, OPTIONS, PATCH, POST, PUT Access-Control-Allow-Origin: https://client-server-domain Access-Control-Max-Age: 86400 Connection: keep-alive Content-Length: 0 Content-Type: text/html; charset=utf-8 Date: Fri, 16 Jul 2021 12:14:54 GMT Server: nginx Vary: Origin The headers … -

How to use gulp in django project

When I added the HTML and CSS files to my project separately, the drop down page on the mobile page did not open. I realized that I had to use the gulp file in the project. But I need to learn the steps to add a template that uses gulp and nodejs. I'm using virtualenv and need to know how to configure the file structure to work properly when running the server?(python manage.py runserver) And another question, to upload the site to the server, what are the conditions for using gulp on a personal computer? -
How to filter from two related models in django

Multiplying the values of two different models in Django
Well i'm trying to create two models whereas the product model is: class Product(models.Model): id = models.AutoField(primary_key=True) price = models.FloatField(null=False) inStock = models.BooleanField(null=False) and another model for cart where: class Cart(models.Model): productID = models.ForeignKey(Product,on_delete=models.CASCADE) quantity = models.IntegerField() total I want total here to equal Product.price multiplied by the Cart.quantity Is there a way how can I achieve it on Django? -
Valid (?) JSON data causing errors in Django, must be served to frontend as string and converted by JSON.parse() in javascript - why?
I have a JSON file hosted locally in my Django directory. It is fetched from that file to a view in views.py, where it is read in like so: def Stops(request): json_data = open(finders.find('JSON/myjson.json')) data1 = json.load(json_data) # deserialises it data2 = json.dumps(data1) # json formatted string json_data.close() return JsonResponse(data2, safe=False) Using JsonResponse without (safe=False) returns the following error: TypeError: In order to allow non-dict objects to be serialized set the safe parameter to False. Similarly, using json.loads(json_data.read()) instead of json.load gives this error: json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0) This is confusing to me - I have validated the JSON using an online validator. When the JSON is sent to the frontend with safe=False, the resulting object that arrives is a string, even after calling .json() on it in javascript like so: fetch("/json").then(response => { return response.json(); }).then(data => { console.log("data ", data); <---- This logs a string to console ... However going another step and calling JSON.parse() on the string converts the object to a JSON object that I can use as intended data = JSON.parse(data); console.log("jsonData", data); <---- This logs a JSON object to console But this solution doesn't strike me as a complete …
