Uploading Json to django model database results in Key Error
I have a custom manage.py command which I am using to upload a json file (a list of dictionaries) to my model. It appears to upload two records fine, but then throws a key error: KeyError: 'headline' My code is as follows: class Command(BaseCommand): def handle(self,*args,**options): filename = '/DoJ_Data_01-12-18.json' newpath = str(Path(home))+filename with open(newpath) as json_file: data = json.load(json_file) for d in data: q = doj(headline=d['headline'],topics=d['topics'],text=d['text'],url=d['url'],date=d['date']) q.save() As far as I can tell the json is valid. What am I missing? -
Python: Deserializing an object of type 'str' to OrderedDict
I'm sending my json to Django server but the problem lies when I want to send a list of dictionaries to it. I have a Load namedtuple which has a legs attribute that is a list. I have a Leg namedtuple that takes in strings. def test_upload_load(self): from collections import namedtuple load_attributes = 'reference miles rate legs' leg_attributes = 'ref f_code f_date t_code t_date' Load = namedtuple('Load', load_attributes) Leg = namedtuple('Leg', leg_attributes) f_date, t_date = str(datetime.now()), str(datetime.now()) load = Load(miles=234.3, rate=432.4, reference='112FR3XSR', legs=[]) leg1 = Leg(ref='1112222', f_code='SSS', f_date=f_date, t_code='XXX', t_date=t_date) load.legs.append(leg1._asdict()) res = self.client.post('/post/create_load/', js) Here's the function that receives the data, but legs is of type str. If I do print(type(legs)), it says type str, when it should be OrderedDict. I tried deserializing it by using json.loads but I get the following error: json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0) Here's the code that makes the error: @api_view(['POST']) def save_load(request): reference = request.POST.get('reference') miles = request.POST.get('miles') rate = request.POST.get('rate') legs = request.POST.get('legs') print(json.loads(legs)) return Response(status=status.HTTP_200_OK) I pretty much want legs to be turned into an actual dictionary which I can retrieve values from. -
Error while installing mysqlclient in django project

Django using NGINX, WSGI and gunicorn give 404 on all pages except root
I'm trying to get a production server running for my Django app, but am having issues with 404 errors on every page except the root webpage. I can access it through the url or the ip address and get the main page to render, but any of the other pages don't work. I had the page working on a sandbox server, and the 404 pages are nginx, not django 404 pages, which makes me think it's something to do with how I've configured my nginx sites-available file. server { listen 80; server_name <url> www.<url> <ip_address>; location = /favicon.ico {access_log off;log_not_found off;} root /home/ubuntu/<directory>/mysite; location = /static/ { root /home/ubuntu/<directory>/mysite/; } location = /media/ { root /home/ubuntu/<directory>/mysite/; } location = / { include proxy_params; proxy_pass http://unix:/home/ubuntu/<directory>/mysite/mysite.sock; } } For the page that returns properly, I get all the static files (css,img) that are expected. I've looked at the nginx error log and get this: 2018/12/02 20:50:11 [error] 11506#11506: *3 open() "/home/ubuntu/<directory>/mysite/about.html" failed (2: No such file or directory), client: XXX.XXX.XXX.XXX, server: <url>, request: "GET /about.html HTTP/1.1", host: "www.<url>.com", referrer: "http://www.<url>.com/" 2018/12/02 20:55:41 [error] 11577#11577: *2 open() "/home/ubuntu/<directory>/mysite/about.html" failed (2: No such file or directory), client: XXX.XXX.XXX.XXX, server: <url>.com, request: "GET /about.html … -
DjangoREST get object from IntegerField
So I'm doing a little project in Django REST, and I'm still getting used to the ORM. I'm dealing with the following Django model: class Session(models.Model): date = models.DateTimeField(default=now, blank=False) owner = models.ForeignKey(settings.AUTH_USER_MODEL, related_name='efforts', on_delete=models.CASCADE) I'm particularly interested in the number of session each owner has, given a specific month. As follows: Session.objects.filter(date__gte=start, date__lt=end).values('owner').annotate(num_sessions=Count('owner')).order_by("owner") This query produces results of the following structure: (owner, count) In the serializer, I'd like to use the owner to retrieve the user name, as to structure the response. I'm having absolutely no luck in doing so. My serializer looks like this at the moment: class SessionAggregateSerializer(serializers.ModelSerializer): num_sessions = serializers.IntegerField(read_only=True) owner = serializers.IntegerField(read_only=True) class Meta: model = Session fields = ('id', 'owner', 'num_sessions') Anyone any suggestions on how to approach this? For regular queries, I'm using the following line to retrieve the users' name, but this is no longer applicable in the current setting: owner = serializers.ReadOnlyField(source='owner.username') -
Keep instance of files when there's validation error on post
I'm having some problems with the instance of these gallery files and other on my project. When I have validation errors, the files uploaded disappear. In this case I wanted to force the user to input at least 3 images to the gallery, but if he only chose one, and sent the form, after the POST the image will appear there, but if he only fill the rest and press send, it will say that he didn't fill the first one he sent last time, because it was only showing, but didn't send that instance again to the form for some reason... The objective is to keep the images uploaded on memory even if the user press the save button again and again with the errors so that he can only fill the ones remaining. attachments.form.html <div class="form-group"> <div class="col-sm-3 control-label"> <label class="">Gallery</label> <br><br> <small>Add photos to your project</small> </div> <div class="col-sm-9"> <div class="row"> {{ gallery.management_form }} {% for form_gallery in gallery %} <div class="col-lg-10 gallery-formset"> <p class="file-description"> {% if form_gallery.file.value %} {% if gallery.non_form_errors %} <span class="filename"> <a class="text" href="#">{{ form_gallery.post_file_name }}</a> <span class="btn-delete glyphicon glyphicon-remove"></span> </span> {% else %} <img width="150" class="media" src="/media/{{ form_gallery.file.value }}"> {% endif %} … -

Django: Why are my static files not showing up and always giving me a 404 error when DEBUG=False?
I am working on my Windows Machine, trying to develop multiple apps for a project called "portal". After working on it, I have set DEBUG=False, and now all my static files are giving me a 404 error after loading any page.

Creating new object returns field with None value
I'm trying to create a new object of my model, but keep on getting a value of none for one field. My models look like this: class KeyCategory(models.Model): program = models.ForeignKey('Program', verbose_name='Programm', on_delete=models.CASCADE) name = models.CharField('Name', max_length=100) events = models.ManyToManyField('Event', through='EventQuota') class Meta: verbose_name = 'Category' verbose_name_plural = 'Categories' ordering = ['name'] unique_together = ("program", "name") permissions = ( ('view_key_category', 'Have access to categories'), ) class EventQuota(models.Model): key_category = models.ForeignKey(KeyCategory, on_delete=models.CASCADE, related_name='key_quota') event = models.ForeignKey('Event', on_delete=models.CASCADE, related_name='key_quota') quota = models.PositiveIntegerField('Quota', default=0) class Meta: verbose_name = 'Quota' verbose_name_plural = 'Quotas' unique_together = ('key_category', 'event') When I try now to create a KeyCategory and my EventQuota, the field "events" for KeyCategory always returns core.Event.None if program.pk == 1: for _ in range(0, 2): access_code_category = AccessKeyCategory( program=program, name=random.choice(self.eventList) ) access_code_category.save() event_quota = AccessKeyEventQuota( access_key_category=access_code_category, event = random.choice(eventList), quota = random.randint(0,100) ) event_quota.save() Note: the eventList in the random.choice is a queryset list of objects.

Phantom style in django project
I'm working on my first real django project, and was fiddling around with the css, but the changes I made did not have any effect on the site. I tried changing things on all 3 of the css files but nothing changed. I then deleted the files (from the project I still have them), and still nothing changed. My site is getting styled, I checked all of my html to make sure there was no inline style in there. All the html files are working, when I change them the site changes. Is this some weird caching thing? I've tried rerunning the server several times and still my site is getting style, seemingly from nowhere. Anyone have any ideas? -

Django select_related queryset in template not rendering
I have a simple view like so: def classticker(request): tickermodel = Tickers.objects.all().select_related('subsector_fk') form = TickerForm() return render(request, 'feeds/main.html', {'v': 10, 'form': form, 'tickermodel': tickermodel}) tickermodel is successfully returning a queryset with all of the fields in the Tickers table and the Subsector table (through the subsector_fk field). This includes the fields 'ticker', 'company_name' and 'subsector' that I'm using in the template below. When I render my template and iterate through the tickermodel queryset I cannot seem to access fields that are coming from the Subsector table.

how to make a circular level meter django
I am trying to implement a level circular that looks like this circular level meter I rotate the meter by -90deg - works fine I adjust color to red - works fine I use border radius to clip it circular, just like photos - it doesn't work. The background gets clipped, but the foreground (the red level) remains rectangular, no clipping. The CSS definitive guide book mentions that the object continues to be rectangular, no matter how it is rendered or how it looks to you. An example shows that text inside a square container whose corners are rounded, sticks out of the circle, because it lives in the square. Any clues on how to do this? Any help will be greatly appreciated. Best, Juan -

django-tables2 Adding template column, which content depends on condition

Wagtail admin - playing with urls
I created in wagtail a model called Regbox in model.py and also RegboxModelAdmin in wagtail_hooks.py. Wagtail admin includes item Regbox in wagtail side bar menu. Then I programmatically created a new collection, a new group with permissions add, edit, delete Regbox and this group is assigned to new user after registration. New user can add (edit and delete) new Regbox (model Regbox has forein key User) and this new user can see in wagtail admin only his own regboxes (I used queryset filter so that superuser could see all regboxes in wagtail admin and the current user only his own regboxes). But if this new user plays with urls he can see also other regboxes (not only his own regboxes). Could someone please advice me how can I do it in wagtail admin ? Thanks -
Ember JSONAPI Adapter with Django REST framwork json API
I am using EmberJS with django. For my API do I want to use JSONAPI. For this I installed Django rest framework json api. And in Ember do I use the JSONAPIAdapter. When my Ember app tries to get /appointments/ everything is fine and "type": "Appointment" but when my Ember Store tries to save an appointment it goes to the correct URL but "type": "appointments" after some testing I concluded that the only type that works is "Appointment", not "appointment" and neither "appointments" or "Appointments". I don't know why the Ember JSONAPIAdapter does this, but is there a way to fix this problem? -

Migration Issue Django, No Migrations To Apply to New DB
I feel like I understand how migrations work, but I am running into what seems to be a strange issue with migrations today. I created a DB in my settings file (and obviously on the server), but when I run the migrations to sync the Models with the DB I am being told there are no migrations to apply. I had 2 DBs on my server: test_universal and test_client. Now I have a new one, which is a 'real' client titled _6_. When I created test_client I ran the same migrations you see below and they worked. I have read that the migration table may be causing this but I am moving to a new DB so that can't be right. What is going on? py manage.py migrate objects_client --database=_6_ Operations to perform: Apply all migrations: objects_client Running migrations: No migrations to apply. py manage.py migrate objects_client 0001_initial.py --database=_6_ CommandError: Cannot find a migration matching '0001_initial.py' from app 'objects_client'. py manage.py showmigrations objects_client objects_client [X] 0001_initial [X] 0002_auto_20181119_2025 # there is nothing in the default db either py manage.py migrate objects_client Operations to perform: Apply all migrations: objects_client Running migrations: No migrations to apply.
