Django forms not working on DigitalOcean Server
Hi I've recently been trying to deploy a Django web app on a DigitalOcean Ubuntu 16.4 server, and was finally able to have the views load with uWSGI, nginx, and lets encrypt for a secure connection. My only issue is: there are a few views which rely on submitting a django form to retrieve objects based on distance from the user (GeoDjango query in the view). The form in question looks like this: <form method= 'get' action="/foo/">{% csrf_token %} <input id='latload' type= 'number' step='any' value='0' name='latitude' style="display:none"> <input id='lonload' type= 'number' step='any' value='0' name='longitude' style="display:none"> <p id= 'walltext' >Here you can listen to the sounds in your area. To use your current location, turn GPS on <input class="btn btn-success" style="color:#34373a;" font-size: 25px; width: 100% value="Get Location" onclick="getLocationWall()" /> , then click </p> <input class="btn btn-success" type='submit' id='submit' value='here' style="color:#1d3b77; font-size: 25px; width: 100%;" disabled /> </form> It takes the lat and long retrieved from a previous Javascript getLocation() function, then is passed to the /foo/ view, which queries objects by distance (GeoDjango) and looks like this: def fetch_places_loc(request): lat= request.GET['latitude'] lon= request.GET['longitude'] finder_location = Point(float(lon),float(lat)) nearby= Places.objects.filter( location__distance_lte=( finder_location, D(km=40))).distance(finder_location).order_by('distance').order_by('-rating__average')[:10] context= { 'object_listboy': nearby, 'title': 'wall', } return render(request, 'location/wall.html', … -

Django - Foreign key, set of ids
Let's say that models are construct like this : class Worker(models.Model): name_char = models.CharField(max_length=4,null=True, blank=True) body_parts_mtm = models.ManyToManyField('BodyPart') class Job(models.Model): job_name = models.CharField(max_length=6,unique=True) job_reference_mtm = models.ManyToManyField('JobReferenceCode') class JobReferenceCode(models.Model): job_ref_char = models.CharField(max_length=13) worker_mtm = models.ManyToManyField('Worker') class BodyPart(models.Model): body_part_name_text =models.TextField() class MembersSimilarity(models.Model): similarity_score_float = models.FloatField(max_length=10) worker_fk = models.ForeignKey(Worker,on_delete=models.CASCADE) job_fk = models.ForeignKey(Job,on_delete= models.CASCADE) #not sure if I need this field to do what I want but here it is: bodypart_fk = models.ForeignKey(BodyPart,on_delete=models.CASCADE) On my website user can look for a JobReference, and I would like to give a specific output : a table where number of lines is controlled by combination of (Job,[BodyParts]). In order to do it, on my view, I think what a found to solve this problem is to make a function that that has this structure (simplified): job_ref_code = 1 job_query = Job.objects.filter(job_reference_mtm=job_ref_code) for job in unique_job_query: sims = MembersSimilarity.objects.filter(job_fk=job) workers_from_sim= Worker.objects.filter(id__in=sims.values('worker_fk')) unique_ids_list = [] for worker in workers_from_sim: combination = set(worker.cath_mtm.all()) if combination not in unique_ids_list: unique_ids_list.append(combination) #All of this "for worker" loop to construct this list; do I need to acces like it ?

How to set up nginx, django, uwsgi and postgressql in two different droplets on digitialocean?
I currently have a droplet in digitialocean which host both the mariadb database and django app. I use nginx as the public web server and uwsgi to communicate with the django app via socket. I want to separate the database and django app to two different droplets. But I have no idea how to do it in a proper and secure way. I read that digitialocean doesn't provide true private networking but share the same network with all droplet in the warehouse. I want to know the following: How to secure the communication between the droplets? Should I run postgressql independently or use nginx+postgres in the droplet or any other settings? Do I need to run additional database client in the django app droplet to communicate with postgres? Any extra tips for security and performance is appreciated. -

Django rest framework AttributeError: can't find field on Serializer
Background context I'm using django rest framework and django-rest-auth to build an API. My authentication scheme doesn't use the default authentication of just the email/username and password and requires other data present on the Profile model. For this reason, I'm using a custom registration serializer and overriding the REGISTER_SERIALIZER class in the settings. This is the serializer as follows: class UserRegisterSerializer(serializers.Serializer): username = serializers.CharField( max_length=get_username_max_length(), min_length=allauth_settings.USERNAME_MIN_LENGTH, required=allauth_settings.USERNAME_REQUIRED ) email = serializers.EmailField(required=allauth_settings.EMAIL_REQUIRED) password1 = serializers.CharField(write_only=True) password2 = serializers.CharField(write_only=True) profile = UserProfileSerializer() ..............

Deploying django - what can I run with gunicorn?

It shows the django default welcome screen. But I am taking over this legacy project which is on Django >= 1.5 and gunicorn == 18.0. And I cannot get it running with gunicorn and nginx.

Deserializing a model with an additional field
I'll be as straightforward as possible: I have a Challenge model, which holds information about a certain challenge and the amount of scores it gives. Any User can have multiple Submissions for a given challenge. When querying for a specific Challenge, I want to return JSON with the Challenge's information along with the maximum score that the current request.user has scored. Is there a way to somehow ducktype (attach) the value to the model instance and serialize it with a given Serializer class? What I've found is that ModelSerializer requires the model to have that field itself, where in my case I add it dynamically. What's a good approach to this problem and has anybody had any similar problems? -

I install Django developer panel, but I don't really know how to use this new application (https://github.com/loftylabs/djdevpanel-devtools). Could anyone have time to explain to me how it works? DEBUG = True MIDDLEWARE_CLASSES = [ 'djdev_panel.middleware.DebugMiddleware', <-- Here!!! 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.locale.LocaleMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.security.SecurityMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.auth.middleware.SessionAuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', 'loanwolf.middlewares.LocaleMiddleware', ] and I install correctly the extension Django Developer Panel.
