Django DRF - update profile using serializer + json
I've been bashing my head against the wall on this for about 3 full days now and probably read every thread on SO. Warning = I am not very good with Django REST or indeed Python. To summarise, each user profile has 11 football players they have initially selected. I now want to update/change these players by POSTing json info. views.py elif request.method == 'POST': jsondata = dict(request.data) profile = Profile.objects.get(user=request.user) serializer = ProfileSerializer(profile, data=jsondata, partial=True) if serializer.is_valid(): serializer.save() return JsonResponse(serializer.data, status=201) Serializers.py class ProfileSerializer(serializers.ModelSerializer): """ Serializing all the Players """ #user = serializers.StringRelatedField() GK1 = PlayerSerializer() DF1 = PlayerSerializer() DF2 = PlayerSerializer() DF3 = PlayerSerializer() DF4 = PlayerSerializer() MF1 = PlayerSerializer() MF2 = PlayerSerializer() MF3 = PlayerSerializer() MF4 = PlayerSerializer() FW1 = PlayerSerializer() FW2 = PlayerSerializer() def create(self, validated_data): return Profile.objects.create(**validated_data) class Meta: model = Profile fields = ( "GK1", "DF1", "DF2", "DF3", "DF4", "MF1", "MF2", "MF3", "MF4", "MF5", "FW1", "FW2",) Right now as a test I am trying to update simply GK1. I know that I am getting correct json data via POST. I also know the instance data is the original data. However it just will not save/update!!! I have overridden the update method as a test: … -
Django loop over list from view in html template
I'm asking how I can pick up a for loop in my django class based view to my HTML template. User can check one or multiple checkboxe(s) and I would like to display informations for each checked checkboxes. In my view I have : checkbox_list = self.request.GET.getlist('PUBSDChoice') #Get object id checked by user context_data['checkbox_list'] = checkbox_list for checkbox in checkbox_list: pubsd = Publication.objects.get(id=checkbox) get_request = Download.objects.filter(pub__publication__id=pubsd.id).count() context_data['pubsd'] = pubsd context_data['get_request'] = get_request Now, in my template I have : <table> <tbody> <tr> <th>{% trans 'Publication ID' %}</th> <th>{% trans 'Requests' %}</th> </tr> {% for item in checkbox_list %} # I'm not sure for this loop <tr> <td>{{ pubsd.pub_id }}</td> #Do I have to add item.?? <td>{{ get_request }}</td> </tr> {% endfor %} </tbody> </table> Thank you very much -
Django: How to annotate based on a condition with When/Case?
I have the following models: class Article(BaseModel): """ represents an article fetched """ internal_id = models.IntegerField(unique=True) title = models.CharField(max_length=500) short_title = models.CharField(max_length=500) picture_url = models.URLField(null=True) published_date = models.DateTimeField() update_date = models.DateTimeField(null=True) clip_link = models.URLField() reports = models.ManyToManyField( "Report", through="ArticleInReport", related_name="articles" ) class ArticleInReport(BaseModel): """ represents an article fetched & present in a Report object """ article = models.ForeignKey("core.Article", on_delete=models.CASCADE, related_name='articleinreports') report = models.ForeignKey("core.Report", on_delete=models.CASCADE, related_name='articleinreports') ios_views = models.IntegerField() android_views = models.IntegerField() And I'm trying to do the following in my view (relevant code only): reports_in_time_range = Report.objects.filter(created_date__range=[starting_range, right_now]) last_report = reports_in_time_range.order_by('created_date').last() articles = Article.objects.filter(id__in=unique_articles).distinct('id').annotate( total_views=Case( When(articleinreports__report=last_report, then=F("articleinreports__ios_views") + F("articleinreports__android_views")), default=0, output_field=IntegerField(), )) Basically, I want to annotate all articles with total_views, which should have the following value: 0 if the article does not appear in the latest report through ArticleInReport F("articleinreports__ios_views") + F("articleinreports__android_views") if it does. However, I'm getting mostly 0s for most objects. I've narrowed down the problematic part to this clause: total_views=Case(When(articleinreports__report=last_report,.... This is because when I do this for an article that is 100% in articles: ArticleInReport.objects.get(article=article, report=last_report) I don't get a DoesNotExistError, meaning that the article does have an ArticleInReport associated with it in last_report.

How can I record a instance's create, edit, destroy in the convenient place?
I have a Machine model: class Machine(models.Model): name = models.CharField(max_length=12) type = models.ForeignKey(to=TypeModel) using = models.BooleanField(default=False) I want to record the Machine instance's create, update, and destroy records. So, I have a MachineRecord model: class MachineRecord(models.Model): editor = models.ForeignKey(to=User) machine = models.ForeignKey(to=Machine) old_content = models.CharField(max_length=1024, null=True, blank=True) new_content = models.CharField(max_length=1024, null=True, blank=True) ctime = models.DateTimeField(auto_now_add=True) But, my problem is there are many place for creating and updating the Machine instance. Whether I can create the MachineRecord instance for Machine instance in a centralized place, such as in the Machine class? I mean, if a instance create, update, destroy anywhere, I just pay attention to the centralized place for recording data. -
leaflet getfeatureinformation not working
I'm trying to create a map in django using leaflet and geoserver. After creating the map I wanted to set up the getfeatureinformation function. After setting it up I had to install a plugin on chrom cors in order for this function to work. But this didn't seem a solution. After reading some stuff I thought that my problem is on django cors headers and followed the instructions of other people I tried everything but it didn't work. I also tried to set up a proxy and modify the httpd.conf file under apache/bin and followed these instructions on this question https://gis.stackexchange.com/questions/89172/how-to-configure-proxy-cgi-in-windows-using-apache-and-geoserver but I think this problem may be not related to my problem since the proxy is set up for openlayers. I see that when I refresh the page jquery-3.3.1.min.js and js_vendor_popper.min.js don't run. Can these be the problem why cors headers are not working, I was trying to import tham at my index.html file but still doesn't work. This is my code: index.html {% extends 'workorders/base.html' %} {% block jumbotron2 %} <div class="jumbotron"> <h1>Navbar example</h1> <p class="lead">This example is a quick exercise to illustrate how the top-aligned navbar works.

Jinja doesn´t render Django view
I´m working on a Django application but jinja doesn´t render the view. I need to separate those templates because I want to include specific content. When I open data.html and data2.html I can see the values "1" respectively "4". But when I open test.html I don´t see the values. And multiple {% extends %} don´t work.

How to avoid combinatorial explosion in unit testing Django views
I have a rather complicated Django (Rest Framework) view which updates an object in the database. In order to update the object, some conditions need to be met (these aren't the real conditions, but they're similar): The user has to be logged in The username needs to begin with admin The update data needs to be valid according to some rules A separate expensive function is_moon_phase_ok needs to return True I'm trying to write a solid set of unit tests for this view and the scenarios that I've come up with are the following: when not logged in, return 401 when not logged in, return {"fail": "login"} when not logged in, don't touch database when not logged in, don't check moon phase when username is not admin_*, return 401 when username is not admin_*, return {"fail": "username"} when username is not admin_*, don't touch database when username is not admin_*, don't check moon phase when invalid data, return 400 when invalid data, return {"fail": "data"} when invalid data, don't touch database when invalid data, don't check moon phase when logged in, return 200 when logged in, return updated data when logged in, check moon phase when logged in, update database … -
django How to Retrieve Data using POST and returned the data with serializer
How to use POST to retreive single data on models. My idea, at the beginning, was to pass a map of parameters. Then The View, on the server side, would take care of reading the needed parameters in the map and return the response. when i test this on postman, i send request body with username and password, but then its return 'name is required', i want this api work like generics.Retrieve but not with url, but with POST instead Models.py class Member(models.Model): name = models.CharField(max_length=100) password = models.CharField(max_length=100) email = models.EmailField(unique=True) phone = models.IntegerField(default=9999) serializer.py class LoginMemberSerializer(serializers.ModelSerializer): class Meta: model = Member fields =[ 'name', 'password', 'email', 'phone', ] view.py class LoginMemberAPI(APIView): def get_queryset(self): return Member.objects.all() def post(self, request, format=None): serializer = LoginMemberSerializer(data=request.data) if serializer.is_valid(): print(serializer.validated_data['email']) member = Member.objects.get(name = str(serializer.validated_data['name'])) # serializer.save() return Response(serializer.data) return Response(serializer.errors) -

Slow upload speed with Ajax call
I have an interesting problem - I have my own IIS 2016 server, that I use to host a website which allows the users to upload a variety of files - some in text format, the others zip'ed up together. Initially the website would return error 500 from the server when trying to upload something bigger, like ~50MB. I Googled up that IIS requires configuration of maxAllowedContentLength (changed default to 209715200, ~300MB) and FastCGI's parameters for IDLE, ACTIVITY and REQUEST (changed to 600) in order to allow bigger files upload without hitting the file size limit. However, now that the files are getting uploaded, the upload speed for these bigger files slowed down to a crawl. Previously I could upload ~20MB files in 10sec on a local network, while now 50MB takes like ~160sec. Not a linear increase I would expect. My website runs on Django, and my POST method file transfer is carried out by Ajax call in JS: $('#sn').on('submit', function(event) { event.preventDefault(); var post_data = new FormData($("#sn")[0]); $.ajax({ xhr: function() { var xhr = new window.XMLHttpRequest(); xhr.upload.addEventListener("progress", function(evt) { var percent = Math.round(evt.loaded/evt.total * 100) console.log(percent) $('#query_button').attr('disabled', true) $('#query_button').get(0).innerText = "Upload status: " + percent + '%' }, … -

ModuleNotFoundError: No module named 'mod_wsgi.server'; 'mod_wsgi' is not a package
I'm trying to run an Apache 2.4 server with mod_wsgi 4.5 and python 3.6/Django on my laptop running Ubuntu 18, but I'm getting a 500 error. The error is: [Wed Oct 03 20:17:10.146305 2018] [wsgi:error] [pid 15405:tid 140336693888768] [client 127.0.0.1:33306] mod_wsgi (pid=15405): Target WSGI script '/mnt/4e468d61-1820-41ad-8a44-8a356b024106/COP4331/server-side/webserver/mysite/mysite/wsgi.py' cannot be loaded as Python module.

I'm not using a virtual environment, so that's not a factor. I'm really at my wit's end here, so I'd really appreciate if someone could help me. -
Custom command to create Django superuser as part of deployment
The best (or most cited) practice for creating Django superuser account is to create and execute a custom command like so: class Command(BaseCommand): def handle(self, *args, **options): if not User.objects.filter(username="admin").exists(): User.objects.create_superuser("admin", "admin@admin.com", "admin") I don't want to keep password and username in git, which is required for AWS beanstalk deployment. Are there any secure best practices for creating production site? A couple options I'm considering are: eb ssh into instance and create superuser interactively using manage.py. I'm thinking this should be OK since set / stored in remote database instance. Capture the username and password instance from os environment var set via beanstalk console. I.e., something like following instead: def handle(self, *args, **options): if not User.objects.filter(username="admin").exists(): User.objects.create_superuser(os.environ['SU_UNAME'], ... Any thoughts / suggestions appreciated. Thanks!
