Internal Server Error for Django with uwsgi / nginx on Debian8.7
I'm pretty beginner in server technologies and I'm struggling to deploy a Django app to Debian8 server. I've been following : this tutorial but I couldn't start uWSGI service so I followed this recommendation and switched to systemd. Then I've been able to run my app in development mode on port :8000 but couldn't load it in browser. The logs say: no python application found, check your startup logs for errors Above this note in logs it complains on not being able load whitenoise module: File "./testdjango/wsgi.py", line 35, in <module> from whitenoise.django import DjangoWhiteNoise which means (if I'm not mistaken) it doesn't load virtual environment. But if I run uwsgi terminal command uwsgi --http :8000 --chdir /home/djangouser/testdjango --module testdjango.wsgi:application --env DJANGO_SETTINGS_MODULE=testdjango.settings --home=/home/djangouser/Env/myapp_env the app works. I have no ideas why it happens and I'd appreciate any help or guide. I did search before I posted this question here and in fact I've been trying many different solutions without success for the last three days. Because of that my files seems to be messy now. My apologies for that. I use django 1.8, virtualenvvrapper, sudo user named djangouser and the folder structure on the server looks like this: -home | … -

How to cache user.groups in a request so db isn't hit every time you call request.user.groups.all()?
I'm using Django with Django REST and have a user permission system based on user groups. As a result I have to check assigned user groups a few times inside views to see if a user belongs to a certain group using request.user.groups.all(). It works but every such call results in an extra query to db to retrieve groups. I wish I could override some method that pulls a user from a db during authentication before attaching it to a request, so I can add something like User.objects.get(pk=userid).prefetch_related('groups') so no extra calls would be made whenever I access groups further down. -

Customizing RESTful response in django
i'm using iframely to generate a JSON response from a given URL, the URL i'm passing redirects to a page containing a 3d component made with threejs but iframely seem do not support threejs so it does not return a response at all and not an empty response. i had the idea of actually creating a customized response when i call the iframely api. the response is supposed to contain a field called html in which i call the threejs script, and then when i consume this response in the front end, the browser will upload the threejs file and creating the 3d component. so my response should look something like this { "html": "<script src="path/jquery-2.0.3.js"></script> <script src="path/three.js"></script>" } and my code so far is r = requests.get('http://iframe.ly/api/oembed?url=' + url + '&api_key=' + settings.IFRAMELY_KEY) my problem is idon't know how to customize the response -
Append file upload form element using JavaScript in Django
I have a file upload form in my edit_file.html template which opens when I want to edit an already uploaded file, and it looks like this in the browser window: I want to add file's thumbnail beside the file_name.jpg (Remove) links without any other label/grey-panel, below/above it: and on clicking the (Remove) link should bring back the select the file to upload label and the grey panel and hide the thumbnail, as shown in the first image. The file_name.jpg and (Remove) links show because of {{ form.file }} object in my form.html file which looks like this: <div id="form_body" class="form-group {% if form.file.errors %} has-error {% endif %}"> <label class="form_well" class="control-label required" for="{{ form.file.id_for_label }}"> {% trans "Select the file to upload" %} </label> <div class="form_well well file-well"> --> {{ form.file }} //this is the object which stores the "file_name, (Remove) links" if file is present, else it shows an "upload button" <p class="help-block"> {% trans "Accepted file types: pdf, mp3, mp4, doc, docx, jpg, png, gpx, csv, xls, xlsx, gif, tiff" %} </p> </div> <div class="error-block">{{ form.file.errors }}</div> </div> So, to accomplish what I want, I used JQuery to first dynamically hide that Select the file to upload label … -

Navigation links not working in navbar (Bootstrap)(Django)

How to share a session (in Redis) between two web servers running the same django application?
I have this: Server1: runs django server runs redis server (used as cache and session store) Server2: runs django server (same application as above) connects to redis on Server1 and uses it for cache and session store Server1 and Server2 are meant to be load balanced web servers that run the same application, so ideally one should log in to only one of them (and automatically the session would be shared with the other). I am not getting this result now. This is what I have on Server1: CACHES = { 'default': { 'BACKEND': 'redis_cache.RedisCache', 'LOCATION': '127.0.0.1:6379', 'OPTIONS': { 'DB': 1, }, }, } CACHE_TTL = 60 * 15 SESSION_ENGINE = "django.contrib.sessions.backends.cached_db" This is what I have on Server2: CACHES = { 'default': { 'BACKEND': 'redis_cache.RedisCache', 'LOCATION': '<hostname of Server1>:6379', 'OPTIONS': { 'DB': 1, }, }, } CACHE_TTL = 60 * 15 SESSION_ENGINE = "django.contrib.sessions.backends.cached_db" What am I missing? -
Django Rest-Framework Serializer: keyerror thrown on field that certainly exists
In the process of building a django-based web application, I came across an error, which I cannot figure how to solve. In the application, my Angular2 front-end sends a post request, which passes to the back-end a JSON object of the following form: { "variable": { "name": "testVar" } } Upon receiving the request the flow of the program goes to the post function, which is defined in the following view, which inherits from django rest-framework's APIView. class VariableAPIView(APIView): permission_classes = (AllowAny, ) renderer_classes = (VariableJSONRenderer, ) serializer_class = VariableNameSerializer def post(self, request): variable = request.data.get('variable', {}) serializer = self.serializer_class(data=variable) serializer.is_valid(raise_exception=True) return Response(serializer.data, status=status.HTTP_200_OK) The serializer's main logic happens in this snippet of code. class VariableNameSerializer(serializers.Serializer): name = serializers.CharField(max_length=255) def validate(self, data): name = data.get('name', None) if name is None: raise serializers.ValidationError('A variable name is required.') try: value = server.ReadVariable(name) except Exception: raise serializers.ValidationError('A variable with this name could not be found') return { 'value': value, } When the django-server receives a request, I get the following exception: KeyError: 'name' During handling of the above exception, another exception occurred: KeyError: "Got KeyError when attempting to get a value for field name on serializer VariableNameSerializer.

Reading strings from file vs reading them from redis cache?
In a django app, I need to check frequently user posts to determine whether they contain any spam words. I can put the list of spam words either in a list and fetch them from file or I can put them in a database table, cache the table in redis and iterate over redis keys. I'm wondering what would be the difference of these method in terms of application performance? And what is generally considered a better approach? -
Django how to copy and instance of an app which use same models but need to direct to different tables
I have a Django Application that I created but I would like to add another copy of that same application with a couple modifications.

I also would still like to use the same models to the same database but direct them to another set of tables, is this possible? Thanks -
