Django: Why wrong user is associated after login via social auth?
I am trying to implement social auth in Django. The idea is that first user has to login in Django and then can login in google or facebook to further request data. But for some reason, Django associates all social logins in "User social auths" table with admin. Vue is used on frontend, Django on backend. My views.py @api_view(('GET',)) def test_login(request): permission_classes = [IsAuthenticated, ] user = request.user print(user) #prints the right user print(user.id) return render(request, 'connectors/registration/login-popup-url.html') My urls.py path('test_login', views.test_login, name="test_login"), connectors/registration/login-popup-url.html template The url will be renderen in a new window generated by Vue function. HTML templates Vue rejects to open. {% block content %}{% url 'social:begin' 'google-oauth2' %}{% endblock %} Vue function for Google login testLogin: function() { var that = this; console.log(that.accessTokenJWT); //Django simplejwt token fetch('http://localhost:8000/test_login', { method: 'GET', headers: { 'Accept': 'application/json', 'Content-Type': 'application/json', 'Authorization': 'Bearer ' + that.accessTokenJWT }}) .then(function(response) { console.log(response); return response.text(); }).then( function(response) { console.log(response); console.log('http://localhost:8000' + response); window.open('http://localhost:8000' + response, "", "_blank"); //open // social auth in a new window } ); } Vue function for Django login loginDjango: function() { var that = this; fetch('http://localhost:8000/users/login', { method: 'POST', headers: { 'Accept': 'application/json', 'Content-Type': 'application/json' }, body: JSON.stringify({ username: that.django.username, … -

Related to Jenkins, Docker
I am a beginner to DevOps and I have created a new Jenkins project which should build a docker image of a Django project and pushes it to the Docker Hub, then pulls back the image from the Docker Hub and runs it . But when I performed this, getting error as "Value Error: Dependency on app with no migrations: website".

Django REST Framework Delete Method Request receives Forbidden 403

Is there any good way to make string from list of dictionary in python? [duplicate]
I have an idea to convert from list of dictionary to string in python. for example: d_list = [{name:"a", age:26},{name:"b", age:22},{name:"c", age:20}] str_l = "[{ 'name':'a', 'age':'26'},{'name':'b', 'age':'22'},{'name':'c', 'age':'20'}]" like this. When input list of dictionary to db table, I need it. So for this, I have done like this. str_l= "[" for user in d_list: str_l += "{" for attr in user: str += "'" + attr + "':'" + user[attr] + "'," str_l = str_l[:-1] + "}," str_l = str_l[:-1] + "]" But it is not good. So if you have any good idea, please share for me. Thank you. -
How to make a Django application send money to its users using PayPal
I have a Django app for online cockfights. Users can bet if their accounts on the site have balance. They do that by first buying a digital product "Online Sabong Cash-In" through PayPal. The money is sent to the website's PayPal business account. I believe, this kind of transaction is called user-to-website transaction, and I've made this work using django-paypal library. I've followed this tutorial for that simple transaction: https://overiq.com/django-paypal-integration-with-django-paypal/ . Now, I want to give the website the feature where users can cash-out or like withdraw their money if they want. I want to have the website-to-user transaction. How can I do that, please? I've searched on Google a lot and all I see are articles for user-to-website transaction. I've found one way but I don't know how to do it using django-paypal library:https://developer.paypal.com/docs/checkout/integration-features/pay-another-account/. -

Why it seem that for Clour Run Default Service Account cannot be replaced?
I am currently deploying a Django application to GCP Cloud Run. I have replaced Cloud Run Default Service Account (....compute@developer.gserviceaccount.com) with a custom one. But I get an error message: AttributeError: you need a private key to sign credentials.the credentials you are currently using <class 'google.auth.compute_engine.credentials.Credentials'> just contains a token. ... This bit is confusing me: <class 'google.auth.compute_engine.credentials.Credentials'> The error reported of the context of Django Storages which I use to store files. Is this message means the service account which is used by Cloud Run is still the default one (GOOGLE_APPLICATION_CREDENTIALS is set as Compute Engine)? Why not the Custom Service Account is used as an Identity for the Cloud Run? Why Cloud Run still checking the Default one I expected I replaced it with te Custome Service Account? I am a bit new with the IAM, but if somebody could explian why it is happeing would be appriciated. -

Is it ok to calling save method multiple times in same method for django model object?
Say, there is a method creates an model object and adds values to model objects fields. def main_method(): obj, created = ModelA.objects.get_or_create(a="asd", b=1) Some imported data will be append to relevant fields: obj.c = "qwe" obj.d = 2 ... sub_method_1(obj) sub_method_2(obj) Also, there are 2 or more sub methods creates new model objects and link to primary object as foreign key. def sub_method_1(obj): obj_new, created = ModelB.objects.get_or_create(...) obj.e = new_obj obj.save() def sub_method_2(obj): obj_new, created = ModelC.objects.get_or_create(...) obj.f = new_obj obj.save() But than, when sub methods are done and return back to main method, there are also several save method calls available. def main_method(): .... obj.g = "ert" obj.h = 3 obj.save() Is this approach OK in practice, or there should be only one save at the end of the main method with returning new objects from sub methods and assign objects to foreign key fields before saving the main object? -
requests.get() returns an invalid JSON
I am using Django's rest_framework to create a simple API to be called from the front end. This API is supposed to be getting JSON data from openapi.etsy.com, and I am using 'requests' to achieve that. @api_view() @permission_classes((IsAuthenticated, )) def getListings(request): data = request.query_params if data.get('shopCode') == 'etsy': url = 'https://openapi.etsy.com/v2/listings/active' params = dict( keywords=data.get('keywords'), limit=data.get('pageSize'), page=data.get('page'), includes='Images:1', api_key='placeholderApiKey', ) response = requests.get(url=url, params=params) return Response(response) When I try this either by using Postman or from the browser by going to https://openapi.etsy.com/v2/listings/active?keywords=placeholder&limit=placeholder&page=placeholder&includes=Images:1&api_key=placeholder, it simply returns exactly what it's supposed to return: a valid JSON with all the data I need. But the Python function above does not. Instead, it returns something like this: ["{\"count\":45929,\"results\":[{\"listing_id\":979511780,\"state\":\"active\",\"user_id\":68094968,\"category_id\":null,\"title\":\"Pers... I'm not sure what exactly it is, it seems like an array containing a single string that contains the entire JSON but where every double quote has been escaped. Either way, it is definitely not a valid JSON. Reading the docs, it seems like I should be able to get exactly what the API returns by returning Response(response.text), but instead it just returns the thing above but without being inside an array. I thought to try Response(response.json()) as well, even though I'm not 100% sure how … -

How to auto-reload django admin page when some async jobs are making changes in the database?
In my django application, there are multiple async tasks running in the background and when those tasks make some db changes then I'm reloading the admin page manually to see the changes on the gui. How can I automate this feature to make the django admin page live? P.S.- I tried django-livereload-server but that will auto reload when any changes are made in the code. It doesn't take background tasks into consideration.
