django queryset to json list to js array
I am fairly new to json and javascript and I've been trying to pass django queryset to a js array. I've managed to pass the .values queryset to javascript through json. Django to JSON code def getPorts(request): ports = Port.objects.all() data = serializers.serialize('json', ports, fields=('name')) return JsonResponse(data, safe=False) JS where I am currently stuck at $.ajax({ url: 'getPorts, dataType: 'json', success: function(result){ var ports = JSON.parse(result) console.log(ports[0]); } }); ports[0] gives me something like {model: "Coordinator.port", pk: 1, fields: {…}} fields: {name: "Fa0/1"} model:"Coordinator.port" pk:1 proto:Object Is there a way to extract only the 'name' attribute? I've been trying to treat it like a 2d array but I haven't really been successful -
How do I add headers to a python-oauth2 request?
I'm using the python-oauth2 library to send requests to the Twitter API. I want to do a GET users/show request which needs a parameter to specify the user_id, but the small wiki on the official GitHub page doesn't really explain how to add non-oauth HTTP headers to it's requests. By trying to read the code and understand what the right approach was I tried this: get_info_url = 'https://api.twitter.com/1.1/users/show.json' #user is a Django model with the authorization info for the user access_token = oauth.Token(user.oauth_token, user.oauth_token_secret) client = oauth.Client(consumer, access_token) headers = { 'user_id' : user.twitter_id } resp, content = client.request(url=get_info_url, method="GET", headers=headers) print('Content: ' + str(content)) but it prints Content: b'{"errors":[{"code":50,"message":"User not found."}]}'. How should I do it? -
Django SetPasswordForm will not display bootstap class "form-control"
I am trying to make a "change password"-page by using the SetPasswortForm. The problem is that it does not implement the 'class': 'form-control'-attrribute.

Django 1.11.8 - Slug - Unexpected Keyword argument
I am new to django and I have started building my first app a couple of days ago. I first went through the MDN Tutorial and the Django Tutorial - building 2 "dummy" apps.

I am able to accomplish that using in my urls.py and a class-based view, though, I would like to get a cleaner URL using . I would like my URL to look like mysite.com/myapp/my-album-name vs mysite.com/myapp/1 I know they are similar questions that have been asked here, I've went through most of them, read the Django doc about Single Object Mixins, Class Based Views and I am still not understanding how to get slug to work.

Ajax form submit not working second time [duplicate]
This question already has an answer here: Event binding on dynamically created elements? 19 answers I am using Django and here are the get and post methods. After refreshing page, on first form submit, Ajax jquery is called. On success, it returns json.msg which is another form rendered as given in below post call. When I try to submit this rendered form, ajax is not called but it directly calls the django POST method. On ajax success, I tried '$('#school').unbind('submit').submit();'. This way, it ensured to call ajax on every form submit. But, the above method, refreshed the whole page which I do not want. May I know how can I unbind the previous submit without page refresh or get Ajax called(and not direct django post) on every submit. def get(self, request): ... ... return render(request, self.template_name, {'form':next_form_obj}) def post(self, request): ... t = get_template('school/fun_activities.html') msg = t.render({'form': next_form_obj}, request) return JsonResponse({'msg': msg}) Here's the Ajax call. $('#school').on('submit', function(event){ $.ajax({ type: 'POST', url: '/school/fun/', data: $("#school").serialize(), success: function (json) { event.preventDefault(); $('#msg-list').append(json.msg); #json.msg is another form }, error: function(data) { $("#msg-list-div").html("Something went wrong!"); } }); return false; }); HTML: <form id = "school" method="post" action="."> <input type="submit" value="Next" /> </form> -

StreamField – TypeError: 'bool' object is not iterable
Build: Wagtail CMS(1.13.1) with Django(1.11) in python3.6. I am trying to create a pretty basic Streamfield block(CardBlock), but keep getting a type error. It is very similar to the examples in documentation, but I can not get it to work... class CardBlock(StructBlock): image = ImageChooserBlock() heading = CharBlock(classname="full title") caption = RichTextBlock() class Meta: icon = 'image' class HomePage(Page): intro = RichTextField(blank=True) showcase_title = RichTextField(blank=True) card = StreamField([('card', CardBlock())], default=True) content_panels = Page.content_panels + [ FieldPanel('intro', classname="full"), MultiFieldPanel([ FieldPanel('showcase_title'), StreamFieldPanel('card'), ]), ] django is trying to "get_db_prep_value()". So, Wagtail tries to "get_prep_value()", for all children(streamchild instances) in value, as shown below. wagtail/wagtailcore/blocks/stream_block.py (line 257): def get_prep_value(self, value): if value is None: # treat None as identical to an empty stream return [] return [ { 'type': child.block.name, 'value': child.block.get_prep_value(child.value), # assign a new ID on save if it didn't have one already 'id': child.id or str(uuid.uuid4()), } for child in value # child is a StreamChild instance ] I am uncertain as to what this value is. What in my block classes needs to be changed to correct this value variable? -

Django: Creating multiple objects of the same instance and then list them in DRF
I want to create multiple objects of the same instance in Django Rest Framework and then return a list of these objects. So lets say I have this model: class City(models.Model): ... class House(models.Model): city = models.Foreignkey(City, ...) ... class Resident(models.Model): house = models.ForeignKey(House, ...) I now want to be able to hit a route with a postrequest like this: localhost:8000/api/city/createresidents/ And get back JSON like this: { [ { residentid = "<some_number>", residentname = "<some_name>", }, { residentid = "<some_number>", residentname = "<some_name>", }, ... ] } And in the body of the postrequest I append information about the House and the created residents, maybe which street it is, what last name the residents have, or some other data about the house or the residents from their respective model. How would I go about doing that if the view should allways create, let's say 4 residents? I tried modifying the perform_create() method of the CreateModelMixin but I could'nt get it to work. Any help would be much appreciated! -
Django fixtures with specific data
I have an app with 3 models that refer to each other in a parent-child way: class A(Model): # ... class B(Model): a = ForeignKey(A) # ... class C(Model): b = ForeignKey(B) # ... In my production database, I have hundreds objects of type A, with thousands of child objects below it. I now want to create a fixture for only a (specific) handful objects. If I run this command, my output will become huge: python manage.py dumpdata ca_myapp -o /tmp/my_app_dump.json However, when I restrict the output using this command: python manage.py dumpdata ca_myapp.A -o /tmp/myapp_dump.json --pks pk1, pk2, pk3 Then only the A objects are deserialized, but not their children. How can I easily create a fixture file with a handful of objects and their children? -

Loading images as base64 calls from Javascript
I am trying to implement a small photo show via a django webserver. Below you can find the javascript code that loads the pictures into the images array and changes the images every x miliseconds. It works if I only load one picture (without the loop) from my django server but it stops working with any kind of loop. I would love to know why it does not work this way and would be more than happy to receive some other feedback about code improvements. I am not very familiar with ajax calls yet. Moreover: Django Templates Engine provides a easy way to simplify urls used in the templates. Is there a way to use the {{% url %}} tag inside a .js File as well? window.images = []; window.current = 0; window.imageCount = 2; function loadImages(){ for(var i = 0; i < window.imageCount; i++){ loadNextImage(i); } showImage(); } function loadNextImage(i) { // https://wiki.selfhtml.org/wiki/JavaScript/XMLHttpRequest/ var xmlhttp = new XMLHttpRequest(); xmlhttp.onreadystatechange = function() { if (xmlhttp.readyState == 4 && xmlhttp.status == 200) { window.images.push("data:image/jpeg;base64," + xmlhttp.responseText); } }; xmlhttp.open('GET', "http://127.0.0.1:8000/mirror/"+i); xmlhttp.send(null); } function showImage() { if(window.current >= window.imageCount){ window.current = 0; } alert("current window count = "+ window.current); document.getElementById('imgshow').src = window.images[window.current]; … -

Recently I've tried using requests to make requests to my local server then use django's unittests to test whether or not they are there. I know usually unittests makes temp database entries then tests those, but I want to test my actual project DBs so I used requests. Problem is for the vader entry it should return false (so I think) because it's missing the conversation_id key. Therefore it doesn't get entered into the DB (I checked it's not there). The Luke entry is there (as it should be). So why is the vader entry returning True? Is it still sending to a temp DB? import requests from django.test import TestCase from convoapp.models import InputInfo from django.urls import reverse import sqlite3 def add_message(request): fields = ['name', 'conversation_id', 'message_body'] if request.method == 'POST': form = InputInfoForm(request.POST) #validate/ DB won't update if form is invalid if form.is_valid(): InputInfo.name = request.POST.get('name') InputInfo.conversation_id = request.POST.get('conversation_id') InputInfo.message_body = request.POST.get('message_body') form.save() else: form = InputInfoForm(request.POST) return render(request, 'blank.html') class InputInfoTestCase(TestCase): def setUp(self): post_request = requests.session() post_request.get('http://127.0.0.1:8000/message/') csrftoken = post_request.cookies['csrftoken'] luke_data = {'name': 'Luke', 'conversation_id': '1', 'message_body': 'I am a Jedi, like my father before me','csrfmiddlewaretoken' : csrftoken} vader_data = {'name': 'Vader', 'message_body': 'No, I am your … -
Django with Gspread and OAuth breaks POST
For a project in Django, we're using Gspread to get data from a spreadsheet and OAuth for authentication. However, since OAuth has been added, POST stops working. The Trainig class with post(): class TrainingList(APIView): permission_classes = (IsAuthenticated,) def get(self, request): worksheet = get_sheet(request.GET.get('sheet', 'Data')) list_of_records = worksheet.get_all_records() return JsonResponse(list_of_records, safe=False, status=status.HTTP_200_OK) def post(self, request): worksheet = get_sheet(request.GET.get('sheet', 'Data')) data = json.loads(request.body.decode('utf-8')) if validate_data_has_all(data): worksheet.append_row( [data["date"], data["days"], data["firstname"], data["lastname"], data["team"], data["training"], data["company"], data["city"], data["cost"], data["invoice"], data["info"]]) return JsonResponse(data, safe=False, status=status.HTTP_201_CREATED) else: return JsonResponse([], safe=False, status=status.HTTP_400_BAD_REQUEST) And the traceback: Traceback (most recent call last): File "C:\Python\backend\env\lib\site-packages\django\core\handlers\exception.py", line 35, in inner response = get_response(request) File "C:\Python\backend\env\lib\site-packages\django\core\handlers\base.py", line 128, in _get_response response = self.process_exception_by_middleware(e, request) File "C:\Python\backend\env\lib\site-packages\django\core\handlers\base.py", line 126, in _get_response response = wrapped_callback(request, *callback_args, **callback_kwargs) File "C:\Python\backend\env\lib\site-packages\django\views\decorators\csrf.py", line 54, in wrapped_view return view_func(*args, **kwargs) File "C:\Python\backend\env\lib\site-packages\django\views\generic\base.py", line 69, in view return self.dispatch(request, *args, **kwargs) File "C:\Python\backend\env\lib\site-packages\rest_framework\views.py", line 489, in dispatch response = self.handle_exception(exc) File "C:\Python\backend\env\lib\site-packages\rest_framework\views.py", line 449, in handle_exception self.raise_uncaught_exception(exc) File "C:\Python\backend\env\lib\site-packages\rest_framework\views.py", line 486, in dispatch response = handler(request, *args, **kwargs) File "C:\Python\backend\unleashedapp\trainings\views.py", line 60, in post data = json.loads(request.body.decode('utf-8')) File "C:\Python\backend\env\lib\site-packages\rest_framework\request.py", line 385, in __getattribute__ return getattr(self._request, attr) File "C:\Python\backend\env\lib\site-packages\django\http\request.py", line 255, in body raise RawPostDataException("You cannot access body after reading from … -
Django multibase administration site
I newbe in Django, so excuse me for question, but I can't find solution. I try to work with multibases. f.ex. (sqlite3). First of it is default (in file db.sqlite3) and second is 'depend' in file depend.sqlite3. I set something in settings.py: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.sqlite3', 'NAME': os.path.join(BASE_DIR, 'db.sqlite3'), }, 'depend': { 'ENGINE': 'django.db.backends.sqlite3', 'NAME': os.path.join(BASE_DIR, 'depend.sqlite3'), } } and after: python manage.py inspectdb --database 'depend' > models.py and change column-key, I have: from django.db import models class AllFiles(models.Model): db_id = models.IntegerField(primary_key=True) filename = models.CharField(max_length=100, blank=True, null=True) ... my router.py states now: class AuthRouter: """ A router to control all database operations on models in the auth application. """ def db_for_read(self, model, **hints): """ Attempts to read auth models go to auth_db. """ if model._meta.app_label == 'depend': return 'depend' return None ... and next I add my 3 tables from new DB into admin-site with: admin.site.register(models.AllFiles) admin.site.register(models.ImportingDict) admin.site.register(models.InputDir) when server (localhost:8000) is running, and admin is logged, I have in admin-view (http://localhost:8000/admin/) 3 new position with 3 new tables, but when try do something with one of them, get: Exception Type: OperationalError Exception Value: no such table: all_files what I missing? what is wrong? Should I register …
