Django 3 - How to create many pages and then show them on menu?
I am new in python Django and practicing it. I have a Wordpress site and I want to migrate it to Django. I can create blogs, pages etc on Django but the problem is I have to make 20+ pages of that site if I move it to Django. And to show them like parent and children of pages.

I want it just like wordpress, create a page, save it and boom, it will be live on frontpage(if configured in settings). I searched for the help or right direction but cant find anywhere. Please someone point me which is the best way to achieve this ? -
Cannot access "instance" or detail view of an object from react frontend with Django rest framework backend
So, I have this view for my models, on a django-rest-framework project class GenreViewSet(viewsets.ModelViewSet): queryset = Genre.objects.all() serializer_class = GenreSerializer permission_classes = [permissions.AllowAny] This is my serializer: class GenreSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = Genre fields = ('name', 'artist', 'albums') depth = 2 On urls: router = routers.DefaultRouter() router.register(r'genre', views.GenreViewSet) urlpatterns = [ path('rest-framework/', include(router.urls)), ] Now, I have a react based frontend app, to access this object, if I access the recordset, meaning, the list of all the objects, then I'm perfectly able to do it, but, if for example, I want to access, just one of the objects in database, something like: path/to/url:8000/object/id Then I got this error, but only from the frontend, the react app: Access to fetch at 'http://127.0.0.1:8000/rest-framework/genre/2' from origin 'http://localhost:3000' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled. Actually, I do have django-cors-headers installed, and also configured on my settings.py file. As I said, I can access the object list, listing all the objects into db, just not the detail. On my settings.py I have: CORS_ORIGIN_ALLOW_ALL = True … -

Can I add a form in django in HTML
I want to add comments form a specific html which has it's separate views and models and I don't want to create a new form.html just to display the form and its views. But I'm stuck.

ModelSerializer write with a field and read with other fields
I POST to an API and relate the created Bar object to an existing Foo object. I use the name of Foo, for example: self.client.post('/app/bar/', data={ 'username': 'nikko123', 'foo': 'Nikko' }, In my Bar Serializer, the Foo field has a ModelSerializer to relate it with, class FooSerializer(serializers.ModelSerializer): name = serializers.StringRelatedField() link = serializers.SerializerMethodField() class Meta: model = Foo fields = ('name', 'link') def to_internal_value(self, data): # Get name of Foo foo = Foo.objects.get(name=data) return {'foo': foo} def get_link(self, object): print('req', object.id) if object.id and request: return request.build_absolute_uri( '/app/foo/{}'.format(object.id)) return None class BarSerializer(serializers.ModelSerializer): foo = FooSerializer(source='*') ... class Meta: model = Bar My problem is that the response from Bar, I get empty from Foo. {'id': 2, 'username': 'nikko123', 'foo': {'link': None}, # name is also missing } I have tested the Bar object and it saved the Foo, however it is not serializing. What could be the problem here? -

Pycharm - is there a key shortcut to stop automatic closure of brackets?
I'm currently playing around with Django using Pycharm and have never used this IDE for Django development before as I usually just used Visual Studio Code or Atom etc. Pycharm has a useful feature for auto closing brackets and expressions, for example, if I type '{%', it will produce '{% %}' with my cursor in the middle. The problem is sometimes I might not want this to happen say, if I'm editing code rather than writing it. What I'm wondering is, is there a way to temporarily over-ride this feature by pressing a key? I don't want to disable the feature entirely as it is otherwise useful. Any help would be much appreciated. Thanks again everyone. -

Django filter out on related field

Python Permission Denied with ffprobe on NamedTemporaryFile
I'm trying to validate certain parameters of a media file before the file gets saved in Django. So I validate the file using ffprobe (from the ffmpeg pip package). with NamedTemporaryFile(suffix=f'.{self.audio.name.split(".")[-1]}') as fp: fp.write(self.audio.read()) try: # Get duration with ffprobe info = probe(fp.name) self.duration = info['format']['duration'] fp.close() except ffmpeg.Error as e: print('stderr:', e.stderr.decode('utf8')) raise NotAudioFile except: traceback.print_exc() raise NotAudioFile This is the snippet that validates the file. self.audio is a Django FileField. It creates a named temporary file, writes the file from the django file, and then validates it using ffprobe. However, when it runs, ffprobe gives me a Permission Denied error, which is weird, since I checked the file and I have full permission to write that directory/file. stderr: ffprobe version 4.3.2-2021-02-20-essentials_build-www.gyan.dev Copyright (c) 2007-2021 the FFmpeg developers built with gcc 10.2.0 (Rev6, Built by MSYS2 project) configuration: --enable-gpl --enable-version3 --enable-static --disable-w32threads --disable-autodetect --enable-fontconfig --enable-iconv --enable-gnutls --enable-libxml2 --enable-gmp --enable-lzma --enable-zlib --enable-libsr t --enable-libssh --enable-libzmq --enable-avisynth --enable-sdl2 --enable-libwebp --enable-libx264 --enable-libx265 --enable-libxvid --enable-libaom --enable-libopenjpeg --enable-libvpx --enable-libass --enable-libfreetype --ena ble-libfribidi --enable-libvidstab --enable-libvmaf --enable-libzimg --enable-amf --enable-cuda-llvm --enable-cuvid --enable-ffnvcodec --enable-nvdec --enable-nvenc --enable-d3d11va --enable-dxva2 --enable-libmfx --enable-libgme --enable-libopenmpt --enable-libopencore-amrwb --enable-libmp3lame --enable-libtheora --enable-libvo-amrwbenc --enable-libgsm --enable-libopencore-amrnb --enable-libopus --enable-libspeex --enable-libvorbis --enable-librubberband libavutil 56. 51.100 / 56. 51.100 libavcodec 58. … -

Django: Getting the currently logged-in user in Dash app
I am using Django-Dash-Plotly module and I am trying to grab the currently logged in user in the Dash app. I have a quick example below: import dash import io import spacy import base64 from dash.dependencies import Input, Output, State import dash_table import dash_core_components as dcc import dash_html_components as html import pandas as pd import time from django_plotly_dash import DjangoDash from sqlalchemy import create_engine import psycopg2 import datetime from django.contrib.auth import get_user_model User = get_user_model() users = list(User.objects.all()) print(users) Regarding the last 4 rows - users = list(User.objects.all()) gives me all available users. Is there any way to manipulate the code such that it only returns the currently logged in user and not every user that exists? Thanks -
Reference before assignment in Django
I am trying to display an error message if a request was not successful. I set a duplicate variable to False, and if an exception is thrown then the duplicate variable should be set to True. However, when the exception is triggered, duplicate will still return False. What am I missing? views.py def generate_hardware_milestone(request): get_request = request.POST.get('form') # creating a formset insert_formset = formset_factory(Forms, extra=0) formset = insert_formset(request.POST or None) duplicate = False try: if request.method == 'POST': if get_request: try: # Execute insertion except Exception as e: duplicate = True except Exception: # some code context = {'formset': formset, 'duplicate_error': duplicate} return render(request, 'example.html', context) -
