Run "git pull" for a Django project running on Windows Server 2016 IIS
My current set up has a Django project running on Windows 2016 IIS. The project is hosted on GitHub for collaboration and I would like to set up a GitHub webhook so whenever there's a push to master branch from any of the collaborators, the IIS Server will run a "git pull" to update the project on the server.

For my CreateView i have some fields = ['subject', 'title', 'slug', 'overview'] on create.html page including slug field which should be populated automatically based on the title field as the user types in. Also i am using the same template for create and edit operation. In the Admin panel i can use prepopulated_fields = {'slug': ('title',)} to get this done and as the user types in this field generates the slug. Here is the related section from views.py class OwnerCourseMixin(OwnerMixin, LoginRequiredMixin, PermissionRequiredMixin): model = Course fields = ['subject', 'title', 'slug', 'overview'] success_url = reverse_lazy('manage_course_list') class CourseCreateView(OwnerCourseEditMixin, CreateView): permission_required = 'courses.add_course' Any help would be appreciated. -
EDIT A FORM IN DIFERENTS TEMPLATE FOR EACH SITUATION DJANGO
I have a model called "" and the same its used to do a form with ModelForm. How you can see, i've done all the views to insert, edit, delete and see data in each template. But, I would like to edit this form in these way: The user will submit the form without fill a unique field After the user submit, I will have a template to show the informations and I would like to have something to approve or reject the form(I thought in a boolean field, with default=false) if I approve: I would like to display the same form with the fields that has already filled when the user submited, but with these fields just readonly and the another field that is empty I would like that the user could fill. After the user fill these field that was empty, he would save the forms and would be dislplayed in another template where I can accepet the answer and "close" the the cicle of the form. There is a way to do this with python/django? maybe just doing a new view. my models: class RegistroFalha(models.Model): nome = models.CharField(max_length=255) tag = models.TextField() status = models.CharField( max_length=50, default='Aberto', choices=( … -
How can i connect webcam stream from javascript to django backend?
I created a djagno website which use OpenCV to connect with webcam and stream it in browser locally and it worked. But when I uploaded the website on Heroku server, it stopped working. So I used javascript to connect the webcam. But the stream I got from javascript did not seems to be connected with my backend. So how can I connect webcam accessed using javascript and send the stream to Django backend and after processing display it back on frontend? Javascript code var video = document.querySelector("#videoElement"); if (navigator.mediaDevices.getUserMedia) { navigator.mediaDevices.getUserMedia({ video: true }) .then(function (stream) { video.srcObject = stream; }) .catch(function (err0r) { console.log("Something went wrong!"); }); OpenCv code class VideoCamera(object): def __init__(self): self.video = cv2.VideoCapture(0) def __del__(self): self.video.release() def get_frame(self): success, image = self.video.read() ret, jpeg = cv2.imencode('.jpg', image) return jpeg.tobytes() I know these are a lot of question, so I am expecting a pathway and keywords from where I can learn these concepts. At least give me some direction so I can learn and accomplish this.
