ModuleNotFoundError: No module named 'ckeditor_uploader' in django
I'm trying to integrate a ckeditor in my django blog application. I followed all the instructions in the github page of django-ckeditor precisely. i.e. installed, added to installed apps, added in urls, collected staticfiles, configured settings in settings.py and imported ckeditor.fields in models whenever necessary.

Django - Haystack Whoosh No Results
I'm using haystack and whoosh for searching. I followed the documentation step by step and already saw these answers: Django-Haystack-Whoosh is giving no results, Django + Haystack + Whoosh, no results in production, django haystack whoosh not showing any errors also no results, no result are found - haystack django whoosh but none could help me.

How to refresh part of a Django page with AJAX?
I am deploying a website using Django. There is an application called 'forum', supporting a discussion forum on my website. The url of the discussion forum is 'XXX.com/forum/roomY'. I want to refresh a div id = ''chat'', which includes a message list, on this page when users click a refresh button. I want to use AJAX to do that. But I find that I could not call the function updatestatementlist(request) to retrieve the updated message list so it can be passed to the on this page. /forum/views.py def updatestatementlist(request): log.debug("call statementlist function") statements = Statement.objects.filter(discussion=discussion) return render(request, 'forum/statementlist.html', { 'statements': statements }) I cannot see the log info so I think by clicking the button I fail to call this function. The main html page of the discussion forum is /forum/discussion.html, which is under the template folder. I extract the html code within the div id = "chat" to a separate html /forum/statementlist.html as suggested here and several other SO posts. /forum/discussion.html <button id = "Refresh"> Refresh </button> <div id="chat"> {% include 'forum/statementlist.html' %} </div> /forum/statementlist.html {% recursetree statements %} {% endrecursetree %} forum.js //When users click the refresh button $("#Refresh").on("click", function(event){ alert("Refresh clicked") $.ajax({ url: '', type: "GET", success: … -

Credentials aren't allowed error when using Outlook REST API Oauth2 in AWS server
I'm trying to implement Outlook Oauth2 in our Django backend server which is hosted on an AWS instance. I carefully followed the instructions in their python tutorial and it works 100% in my local machine. I am able to grab the authorization code which I then convert in my backend server to an access token. The problem lies in our demo server which is an AWS instance. We have a button that redirects the users to Outlook authentication. The URL has the following format: https://login.microsoftonline.com/common/oauth2/v2.0/authorize?client_id=<client-ID-here>&redirect_uri=<demo-server-redirect-url>&response_type=code&scope=openid+profile+offline_access+Calendars.ReadWrite&prompt=consent I am receiving the following error whenever I convert the authorization code into an access token just after the consent screen: { 'error': 'access_denied', 'error_description': 'Your credentials aren't allowed' } The weird thing is that if I use POSTMAN using the demo server Outlook credentials, I am able to retrieve an access token from Outlook. Basically, it works for both in my local machine and using Postman. I really think that I'm just missing a very small piece of code/configuration here. Are there some extra settings that I need to do in order to make Outlook Oauth2 work in AWS? -
how to read Django request.FILES (which is an image) as binary
Sorry for my bad English. I want to get binary image from request which contains image file from ajax. Because when user upload image file, I want to do OCR to the image file using google VISION API. Currently I'm using django, ajax. So when user upload the image, using ajax the file is passed to django view. I tried to get binary file in the views.py. But When I use request.FILES.get('file').read(), there is no data. But request.FILES.get('file').name is 'bank.png'... I think it's weird. Here is some code views.py def receipt_ocr(request): if request.method == 'POST': print(type(request.FILES["file"])) #<class 'django.core.files.uploadedfile.InMemoryUploadedFile'> print(type(request.FILES.get('file'))) #<class 'django.core.files.uploadedfile.InMemoryUploadedFile'> print(request.FILES.get('file')) #bank.png imageFile = request.FILES.get('file') print(imageFile.size) #119227 print(request.FILES.get('file').name) #bank.png print(request.FILES.get('file').content_type) #image/png print(type(request.FILES.get('file').open())) #<class 'NoneType'> print(request.FILES.get('file').open()) #None print(type(request.FILES["file"].read())) #<class 'bytes'> for chunk in imageFile.chunks(): print(chunk) #this generates lot of binary and some rdf:Description rdf:about= ... things receipt_image = imageFile.read() print(type(receipt_image)) print(receipt_image) ajax part // receipt OCR process $.ajax({ url: "{% url 'place:receipt_ocr' %}", enctype: 'multipart/form-data', type: 'POST', processData: false, contentType: false, data: postData, complete: function(req){ alert('good'); }, error: function(req, err){ alert('message:' + err); } }); What I exactly want to do is using this kind of code (google VISION API example code, OCR) def detect_text(path): """Detects text in the file.""" … -

Why is the return value of a model method in Django not showing up to the template?
I have this function inside my model that is not appearing when I try to run the server. I think I am accessing the method correctly but when I tried writing print("ENTER") inside the total_balance() function, nothing showed up which makes me think that it's not even entering the method at all.

Django inline formset with manytomany fields
Ive spent a fair bit of time searching on this subject without finding some real up to date answers. I'm trying to create a form that creates a db entry. The basic idea is this: Many events can have many people So, the struggle here is that the user needs to create an event where the user can select all the people that attend. Each person that attends though, has certain things that also needs to be tracked per event. See the model below: models.py from django.db import models from django.contrib.auth.models import User[] class PersonRole(models.Model): role = models.CharField(max_length=20, choices=ROLE_CHOICES, unique=True) # this function will be invoked when this model object is foreign key of other model(for example Employee model.). def __str__(self): return self.role class PersonClass(models.Model): name = models.CharField(max_length=100, choices=CLASS_CHOICES, unique=True) color = models.CharField(max_length=6, choices=COLOR_CHOICES, unique=True) # this function will be invoked when this model object is foreign key of other model(for example Employee model.). def __str__(self): return self.name class Person(models.Model): name = models.CharField(max_length=100, unique=True) personclass = models.ForeignKey(PersonClass, on_delete=models.CASCADE, blank=True, null=True) personrole = models.ForeignKey(PersonRole, on_delete=models.CASCADE, blank=True, null=True) value = models.IntegerField(default=0) reliability = models.IntegerField(default=0) last_item = models.DateField(auto_now=False, blank=True, null=True) last_event_attended = models.DateField(auto_now=False, blank=True, null=True) last_manager_attended = models.DateField(auto_now=False, blank=True, null=True) item_received = models.BooleanField(default=False) … -

Get images from database as known images for Facial recognition
I am playing around with a time attendance application that is going to utilize facial recognition. When you create a user, you add three pictures of that user and those pictures are saved in the database. Note that I'm using Django and Django models for this. I am thinking of connecting to the database itself because I can't of an easier way of retrieving the images from Django Models outside of Django. Anyways. Consider a standard OpenCV Facial recognition code. It has a thing called known images. What I want to do, is when a user enters their ID, the program retrieves the images of that user. The thing I don't understand, is how do I directly use those images for known_images. Do I first save the images in the OS's temp folder and read from there? Or how do I do this? Thank you, any and all ideas are appreciated. -

Is there any specific way to override search_indexes of oscar core search app?
I am using Haystack with solr back-end in Django-Oscar. I want to override ProductIndex class of core search_indexes. But, the problem is it's not working with the regular way. Firstly, I forked the search app like other oscar apps. And I created custom ProductIndex class inside search_indexes.py file. I also tried excluding core search_indexes in setting. But, it's not taking from the overridden app. My custom class looks like: """ from oscar.apps.search.search_indexes import ProductIndex as AbstractProductIndex class ProductIndex(AbstractProductIndex): def index_queryset(self, using=None): # Only index browsable products (not each individual child product) return self.get_model().objects.all().order_by('-date_updated') def read_queryset(self, using=None): return self.get_model().objects.all().base_queryset() """ The ProductIndex class is supposed to run from my overridden app but, instead it's using core ProductIndex app. -

Map raw sql query with join to model in Django
