OpenStack cloud-config won't run my scripts in windows when I use APIs
My problem is a bit strange, here is the scenario: I want to make a random password ( for ssh ) for every new instance. So I will pass this script in my user_data to OpenStack server. ( I'm using OpenStack APIs ) #cloud-config\npassword: P@ssword\nchpasswd: {{expire: True}}\nssh_pwauth: True It will work properly for my Linux machines ( i.e. ubuntu ) But when I use this command for my windows machines: #ps1\nnet user administrator P@ssword The username and password won't work. I thought maybe my scripts are wrong, so I used the Horizon dashboard and put exactly the same scripts in the user_data text box ( in configuration tab ), and after creating the machine, it worked OK. To sum up, my scripts are working properly on the horizon dashboard. The Linux scripts work Ok in my client ( using APIs ) but the windows command is not working in my client. I've checked the horizon source code and didn't see any difference in passing user_data on windows machines or Linux machines. Thanks a lot. -
How do i make self.request.user.account refer to the new inherited Account?
I am using a ready module "account" and I want to supplement it with the help of inheritance with another attribute "photo". In models.py I create class Account, that inherits from Account from "account" module. extended_account/models.py from django.db import models from account.models import Account class Account(Account): photo = models.URLField(blank=True, default="default") But in views.py I have no idea how to chains my own Account model with PhotoView. self.request.user.account still refers to the Account from "account" model and has no "photo" attribute. How do i make self.request.user.account refer to the new Account in extended_account/models.py? extended_account/views.py from django.views.generic.edit import FormView from account.mixins import LoginRequiredMixin from extended_account.forms import PhotoForm class PhotoView(LoginRequiredMixin, FormView): template_name = "account/new_photo.html" form_class = PhotoForm def get_initial(self): initial = super(PhotoView, self).get_initial() initial["photo"] = self.request.user.account.photo return initial def update_account(self, form): fields = {} if "photo" in form.cleaned_data: fields["photo"] = form.cleaned_data["photo"] if fields: account = self.request.user.account for k, v in fields.items(): setattr(account, k, v) account.save() extended_account/forms.py class PhotoForm(forms.Form): photo = forms.URLField(required=False) -
Django+React: Uploading images to Django media inserted in a Rich Text editor via React
I have a project that solely utilizes Django as web API server and React as its frontend. And I am using Django Rest Framework (DRF) for RESTful API implementation. In this project, I am working on an article module where an author can insert one or more images in between text contents in a rich text editor. Do you have any idea as to the process of communicating React with Django in order to upload those inserted images to my media folder? For sure, the entire article content will be saved as a code snippet (as generated by the rich text editor) that will contain img tags of the inserted images. This code snippet will be saved in my model's content field (TextField). Here is my Article model's struct: class Article(models.Model): title = models.CharField(max_length=250, default="", unique=True) category = models.ForeignKey( ArticleCategory, on_delete=models.DO_NOTHING, related_name="article_category") slug = models.SlugField(max_length=300, unique=True) author = models.ForeignKey( User, on_delete=models.DO_NOTHING, related_name="article_author") content = models.TextField() feature_image = models.FileField( upload_to='article_images/'+str(current_date.year) + "/" + current_date.strftime('%B')) feature_image_caption = models.CharField(max_length=50, default="") publish_date = models.DateTimeField() unpublish_date = models.DateTimeField(blank=True, null=True) published = models.BooleanField(default=False) preapproved = models.BooleanField(default=False) preapproved_by = models.ForeignKey( User, on_delete=models.DO_NOTHING, related_name="article_preapproved_by", blank=True, null=True) approved = models.BooleanField(default=False) approved_by = models.ForeignKey( User, on_delete=models.DO_NOTHING, related_name="article_approved_by", blank=True, null=True) updated_by … -
Django: How to remove a coupon from an order without deleting coupon from database?
Hey guys I have this coupon model, I need to give it a remove functionality (not delete from database), to remove coupon from the order if the customer wishes to. How can I have that functionality?

Why my request session lose data view to another view in auth azure AD?
I'm trying to integrate my django platform with azure ad authentication, so I followed the following document https://docs.microsoft.com/pt-br/graph/tutorials/python.

Django not retaining session through views
I'm developing an application for Bitrix24 and I'm having a problem with sessions. @method_decorator(csrf_exempt, name='dispatch') class IndexView(View): r'''Index View.''' def get(self, request): r'''Manages Bitrix24 authentication redirect.''' return render(request, 'frontend/index.html') # POST working as GET because Bitrix24 does not GET the homepage. def post(self, request): r'''Renders the home page and stores Bitrix24 domain in session.''' request.session['bitrix24_domain'] = request.GET.get('DOMAIN') return render(request, 'frontend/index.html') As soon as the user goes to another view, the session is gone, completely. It also happens locally, if I set a key in session and try to retrieve it from another page, all data is lost too. I'm currently using default settings to Django and using rest-framework.

Django REST RelatedObjectDoesNotExist: User has no userprofile

Launching django and uwsgi with nginx and docker
I'm trying to launch django and uwsgi with docker locally, but I've been unsuccessful so far. I have a slight variation of this setup working in production, so I don't want to mess with it too much, but I do want to have django running locally for some bug fixing.

How to deploy djanjo-angular-postgresql web app using google kubernates engine?
I have a djanjo, angular, postgresql web app that I want to deploy. I never deployed a web app before, so, this is my fist time. I decided to use google cloud platform.

I went through the documentation for kubernates but I don't really seem to understand anything at all. Can someone guide me through how to deploy the previously mentioned app ? -
