Improve Nginx configuration file for Django and static home page
I have setup an Nginx server on an EC2 instance (running ubuntu 16.04). I also have two A value DNS entries, for @ and www, both pointing to the same IP. I only use one certificate for www.example.com, so I point the example.com to www.example.com in Nginx. I feel the website is sometimes slow. I think it has something to do with my Nginx config. Also, I want to make sure that the single certificate idea wouldn't cause any security warnings for clients (I tested it and it seems fine). I'm not awfully familiar with this DevOps kind of tasks, so just want to be sure that I'm not doing some noob mistakes, and that I can safely go with this setting into production. Thanks! Nginx config file: server { server_name www.example.com; access_log /var/log/nginx/example.com.log; error_log /var/log/nginx/example.com.error.log debug; root /home/ubuntu/example.com/homepage; # if the uri is not found, look for index.html, else pass everthing to gunicorn location / { try_files $uri $uri/index.html @gunicorn; } # Django media location /media { alias /home/ubuntu/example-django/public/media; # your Django project's media files } # Django static files location /static { alias /home/ubuntu/example-django/public/static; # your Django project's static files } location @gunicorn { proxy_pass http://0.0.0.0:8000; proxy_set_header Host … -

django group by count on distinct multiple fields
I'm trying to achieve the following SQL statement in Django: SELECT org_type, count(org_type) FROM ( SELECT DISTINCT ON (org_name, org_type) org_name, org_type FROM orgs ) t1 group by org_type I'm running the following, however I'm not getting the correct counts: orgs.objects.values('org_name','org_type').distinct().values('org_type').annotate(Count('org_type')) It looks like the above is the same as running: orgs.objects.all().values('org_type').annotate(count=Count('org_type') -

Custom User registration in django using django rest framework
I'm building a REST backend using django rest framework. Here's my modified User model in django, class User(AbstractBaseUser, PermissionsMixin): mobile = models.CharField(max_length=100, unique=True) email = models.EmailField(max_length=255, null=True) username = models.CharField(max_length=255, null=True) full_name = models.CharField(max_length=255, blank=True, null=True) is_staff = models.BooleanField(default=False) is_superuser = models.BooleanField(default=False) location = models.ForeignKey(Location, on_delete=models.SET_NULL, null=True) Now I wish to expose an endpoint that collects the following data as a POST request - mobile, email, username, full_name, password again. -A Normally to create objects I would use Serializers. But I've no idea how to go about this one. I've checked the following SO question, but it's tailormade for forms. Custom user registration in Django So in essence, I guess my questions is, how can I expose an endpoint to gather the data mentioned in -A above and create an User object from that in django. -
Django - Two fields' can have the same value only if their primary keys are not the same

call a view in another app with additional url parameter or query string
in my explore/views.py I have: class A(APIView): def get(self,request,format=None): #process many query string options and other checkups here return JsonResponse(data,status=status) The view is called from several applications in the following way to avoid reptition. in my second app (second/views.py): from explore.views import A class Show(APIView): def get(self,request,partner_id,format=None): view=A.as_view() return view(request) It does work as expected. But now, I need to adjust something to A view based on partner_id. Is there a way to pass partner_id to explore/views.py A view in a manner that won't affect the current app significantly? The request have the option to pass query string and I am ok to passing partner id as query string. I already tried: explore/urls.py: url(r'^a/$', views.A.as_view(), name='a'), url(r'^a/(?P<partner_id>[0-9]+)/$', views.A.as_view(), name='a'), and adding partner_id=0 to the get method but it doesn't have an effect so far. -
Django testing, can't see anything in test database
I am running some tests in Django using from django.test import TestCase and subclassing that. My tests run, but when I step through them in debug mode, I want to check what is happening in MySQL. But I can't see anything in MySQL. (I am using a settings file that points to a local instance of MySQL for the tests). Logging into MySQL via the command line, or Pycharm I can see that he test_database gets created correctly (and torn down after the test have run. But when I query any tables they via the mysql client, they are empty. I can use the ORM to do CRUD operations on the database and they behave as expected (viewing the objects in PyCharms debugger). Why can't I see any data in MySQL? Are the tests wrapped in some transaction so that a different login won't see those changes? Is there a setting I need to change? -
React Native Fetch API - can't access son or body of response
Trying to call an API to my backend with Fetch, but I can't access the response body. There's a loot of different notation and syntax about this on the internet and I can't figure out how to do it properly. I've tried response.json() and responseJson, and stringyfying both. I don't get what I want which is the actual body of the response. It's meant to have a key/token that I then save. responseJson returns this: responseJson: {"_40":0,"_65":0,"_55":null,"_72":null} This is my function: export function LogIn(em, pass) { return (dispatch) => { console.log('LogIn called'); dispatch(logInIsLoading(true)); //from phone *fetch('http://192.168.1.18:8080/rest-auth/login/', { method: 'POST', headers: { // 'Accept': 'application/json', 'Content-Type': 'application/json', }, body: JSON.stringify({ 'email': em, 'password': pass, }) }).then((response) => { console.log("response " + JSON.stringify(response)); if (!response.ok) { console.log("ERROR: " + response.statusText); throw Error(response.statusText); } dispatch(logInIsLoading(false)); return response; }) .then((response) => { responseJson = response.json(); console.log("responseJson: " + JSON.stringify(response.json())); return responseJson }) .then((responseJson) => { AsyncStorage.multiSet([['key', responseJson.key], ['loggedIn', true]], () => { console.log(responseJson.key); dispatch(isLoggedIn(true)); dispatch(getKey(responseJson.key)); }); })* .catch(() => dispatch(logInHasErrored(true))); }; } -
python3 pip3 and django 2 confusion
I'm new to Python so please help me understand this: From Django's documentation: I need python 3+ to run Django 2+ and I need to check my version by running this: $ python -m django --version $ python --version Python 2.7.14 $ python -m django --version 1.11.10 However I've installed python3 and pip3 in order to install (or upgrade?) Django 2 so: $ python3 -m django --version 2.0.2 It seems to me that there are 2 python run parallely on my machine (Linux Ubuntu 17) so what I did was not upgrading Python, pip or Django but installing a newer version of them. Some answers on stackoverflow suggest that I should not use pip3 to upgrade Django. So how do I use python3 to test my app and work with Django 2? From Django's documentation, all commands for Django 2 use python, not python3. Should I assume they mean python3? -

Can't text compare Django model field
I have a "Report" model set up in Django that represents a specific report uploaded to the site. This model has a ForeignKey relationship to a "UserTechnology" model which is a list of all the available ways an end user can access the uploaded reports. I am displaying these reports and some information about them on the index.html page. I'd like to switch the url passed to the where we link the report based on the "UserTechnology" value that the specific report has. The problem comes when trying to compare a report's UserTechnology value to anything. For example, if I just display {{ report.UserTechnology }} it works fine, with an example value of "FileManager". But if I try something like {% "file" in report.UserTechnology %} or {% report.UserTechnology == "FileManager %} it always returns False. I think the problem is that I'm not comparing what I think I'm comparing when dealing with ForeignKey relationships, but I'm not sure how to access the value of UserTechnology.Name for a specific report other than report.UserTechnology. models.py: class Report(models.Model): Name = models.CharField(max_length=200, default=None, null=True) LastUpdated = models.DateTimeField('date published', default=None, null=True) SharePointURL = models.CharField(max_length=500,default=None, null=True) FileManagerLocation = models.TextField(default=None, null=True) ReportText = models.CharField(max_length=400, default=None, null=True) ReportImage … -
Trying to access model in form by going through another model
I am not that good at queries, so I need some help. I have a Course model, and a TeacherData model. Each teacher has its own courses. But when a teacher makes an account I use a Teacher model. And if teacher_ID column from TeacherData doesn't match the one entered by the user, the account cannot be created. Now, in my form I need to show Courses for each teacher, so that a Lecture instance can be created. I was thinking to use teacher_ID as bridge connecting Teacher model with TeacherData model and then I would be able to show the courses that only a specific teacher has. This is what I tried: class LectureForm(forms.ModelForm): lecture_title = forms.CharField(max_length=100, required=True) course = forms.ModelChoiceField(initial=Course.objects.first(), queryset=Course.objects.filter( Q(teacher1__surname__in=[t.surname for t in TeacherData.objects.filter( Q(teacher_ID__iexact=[x.teacher_ID for x in Teacher.objects.all()]))]))) class Meta: model = Lecture fields = ('course', 'lecture_category', 'lecture_title', 'content') -
Conversion to python of C code
For use in a web backend (django) project, I am given the following C code snippet: /* architecture is x86_64, strings are ASCII */ /* example output: * 7KL753WG => 680403628 * 043NM2B6 => 517135930 * 7B6ISP72 => 058511020 */ char buf[33]; char* unlock(char *s) { char token[9]; char scrambled[9]; long long *ltoken; strncpy(token,s,9); ltoken=(long long *)token; *ltoken *= 610; *ltoken ^= 0x5A5A5A5A ; buf[32]='\0'; int i = snprintf(buf,32,"%lld",*ltoken); return buf+i-9; } In words: take an 8 char ascii string, use its bit pattern as a long, apply a couple of computations, take the last 9 digits of the result. For obvious reasons, I'd hate to shell out to call the binary, and would like to convert it to python 2.7. On the other hand, I have tried the obvious (struct.pack, struct.unpack) and the exotic (ctypes) with no joy. I assume ctypes is the way to go, but I have never used it so my attempts are basically poking at it with a stick. (And yes, I know that the algorithm itself is not pretty - luckily not something I wrote) TIA -
In Django, how do I add the contents of two fields and display the results in a third field?
I'm trying to learn Django and am finding it frustratingly difficult to do fairly basic things. I have the following form classes: from django import forms class InputForm(forms.Form): field1 = forms.FloatField(label="First field: ") field2 = forms.FloatField(label="Second field: ") class OutputForm(forms.Form): outfield = forms.FloatField(label="Result: ") And the following template: <form> {{ input_form.as_ul }} </form> <form action="#" method="get"> <input type="submit" class="btn" value="Submit" name="submit_button"> </form> <form> {{ output_form.as_ul }} </form> And finally, the following view: from django.shortcuts import render from .forms import InputForm, OutputForm def index(request): if request.GET.get('submit_button'): # ????? else: input_form = InputForm() output_form = OutputForm() return render(request, 'index.html', {'input_form': input_form, 'output_form': output_form}) All I want to happen is that when I hit the submit button, the values in first field and second field get added and displayed in the result field. I know from debug outputs that the ????? commented block is run when I press the button, but I have so far not been able to figure out what to do to actually access or alter the data in my fields. I don't care about keeping a record of these transactions so it feels like storing these in a database is tremendous overkill. What is the correct way to approach … -
Django migrations: how to conditionally switch between migration statements according to current DB backend?
I use Django with SQLite in my dev environment and postgreSQL in production. I know that having different DB backends for dev and prod is a tech debt, but this is the current state of affairs for now (not for long, hopefully). I would like to take advantage of the postgres JSONField in production while in dev keep using django-jsonfield. Is there a way to write a migration so that it can conditionally switch between the two types of field depending on which backend is currently being used?
