How to load file contents to ace editor
I set up a django website allowing users upload .txt files, and I want to add editing function by integrating ACE editor (or any other editor suggestions?). I have a list of my uploaded files, and I want an edit button to redirect to editor page with loading the file content in the editor page. I am wondering how to load file content to ace editor? I found some code about uploading file and displaying them in editor directly.(https://jsfiddle.net/xlaptop2001/y70gL3kv) However, what I want is to redirect to a new editor page with loading the file that already uploaded by clicking on 'edit' button. {% extends 'base.html' %} {% block content %} <h1>Mechanism {{ object.id }} details</h1> <style> ul.b { list-style-type: square; line-height:200%; } </style> <ul class="b"> <li> {% if object.ck_mechanism_file %} <a href="{{ object.ck_mechanism_file.url }}">{{ object.ck_mechanism_file }}</a> <a href="/ace/"> <button type="button" class="btn btn-primary btn-sm">Edit</button> </a> <a href="delete_mechanism"> <button type="button" class="btn btn-danger btn-sm">Delete</button> </a> {% else %} <span class="text-muted">No Mechanism File Attached</span> {% endif %} </li> <li> {% if object.ck_thermo_file %} <a href="{{ object.ck_thermo_file.url }}">{{ object.ck_thermo_file }}</a> <a href="/ace/"> <button type="button" class="btn btn-primary btn-sm">Edit</button> </a> <a href="delete_thermo"> <button type="button" class="btn btn-danger btn-sm">Delete</button> </a> {% else %} <span class="text-muted">No Thermo File Attached</span> … -
ProxyError while using "requests.post()" in Python/Django
I try to call a java-based web-service in python code, using requests.post() as follows: endpoint = 'http://**.**.**.**:8080/MyApp/services/Services/login' def index(request): post = request.POST if request.POST.get('login_button'): qd = QueryDict(mutable=True) qd.update( inputPhoneNumber=request.POST.get('phone_num'), inputPassword=request.POST.get('password') ) messages.info(request, '{}?{}'.format(endpoint, qd.urlencode())) response = requests.post('{}?{}'.format(endpoint, qd.urlencode())) result = response.json() messages.info(request, result) return render(request, 'login/index.html') However, proxy blocks my request. I suspect that this happens because the web-service uses http protocol. After 30 hours of searcing, I could not find anything to solve this problem. I've tried changing http to https but that caused another error. For the record, I can access web-service's url by manuel on browser, but I cant, on django.

Django Model Type
My goal is to have a model structure like the below: Course Section Subsection For each course there can be multiple sections. And each section can have multiple subsections. class Course(models.Model): title = models.CharField(max_length=200) def __str__(self): return self.title class Section(models.Model): course = models.OneToOneField( Course, on_delete=models.CASCADE, ) title = models.CharField(max_length=200) def __str__(self): return self.title class SubSection(models.Model): title = models.CharField(max_length=200) course = models.OneToOneField( Course, on_delete=models.CASCADE, ) def __str__(self): return self.title However, when i test this via the admin, I can create a course, but not a section? # cat course/admin.py from django.contrib import admin from .models import Course admin.site.register(Course) Any ideas on where im going wrong? -
Maximum call stack size exceeded error on JQuery Autocomplete Lookup
I have the following code: var person_names = JSON.parse(document.getElementById('person_names').textContent); $('#autocomplete_person_names').val(''); var selected_person = null; $('#autocomplete_person_names').autocomplete({ lookup: person_names, showNoSuggestionNotice:true, maxHeight:200, onSelect: function (suggestion) { selected_person = suggestion.value; } }); For some reason I get the uncaught type error Maximum call stack size exceeded in my console. When I check line by line, I found out the error is because of the following line: lookup: person_names, As far as I have found out by searches until now, the Maximum call stack size exceeded is because of recursive functions. But I cannot understand what kind of recursive behavior the lookup brings here. What could be the problem here? Another thing: the variable person_names gives an array and works fine. And I am using this inside an html template inside a Django project. The full error in console looks like this: Uncaught RangeError: Maximum call stack size exceeded at Function.map (jquery-3.3.1.js:462) at b.verifySuggestionsFormat (jquery.autocomplete.min.js:8) at b.setOptions (jquery.autocomplete.min.js:8) at new b (jquery.autocomplete.min.js:8) at HTMLInputElement.<anonymous> (jquery.autocomplete.min.js:8) at Function.each (jquery-3.3.1.js:354) at jQuery.fn.init.each (jquery-3.3.1.js:189) at jQuery.fn.init.a.fn.devbridgeAutocomplete (jquery.autocomplete.min.js:8) at HTMLDocument.<anonymous> ((index):3734) at c (jquery.min.js:4) -
Syntax Error after adding knox to urls.py
I am new to Django and django-rest-framework. I am building an API and I want to implement auth using Django-rest-Knox. I have added Knox to the installed apps in the settings.py.

Django - Retrieve Different Post Types Based On TimeStamp
I am working on a little Django project. The user can create two types of Posts: Image & Video . Here, the different classes I have created (for the sake of brevity, I excluded some fields): class VideoPost: videoData = ... class ImagePost: imageData = ... So, when I combined the project with an Android app to display the posts on the screen, then I faced the problem how to retrieve the different posts once. I could not come up with a solution. Let's say, the user has created video and image post objects with the following order: VideoPost1 -> ImagePost1 -> ImagePost2 -> VideoPost2 How can I retrieve them in that order ? So, how to get a that mix of video and image posts based on creation time ? At the moment, I can only make separate queries like: # the view responsible for listing VideoPost instances .... return VideoPost.objects.all() # the view responsible for listing ImagePost instances .... return ImagePost.objects.all() I do not want to sort the instances on the frontend (Android app). So, is there a way to sort and query the different instances on the backend (Django) -
How do I allow model serializer to set model's foreign key field to null?
I want to be able to set the borrower field (a foreign key) in my Asset model to be NULL but I can't seem to get it to work. I'm trying to send a PATCH request with JSON data that has the key borrower equal to value of NULL but the borrower field won't get updated to NULL for the model instance. Perhaps there is an issue with the serializer that is preventing the foreign key field from being able to be set to NULL? I have already tried passing in allow_null=True to BorrowSerializer class but that hasn't worked. I've searched high and low on StackOverflow for posts with similar problems and solutions but nothing I've tried has worked. Here is my models.py: from django.conf import settings from django.db import models from django.utils import timezone from datetime import date from django.contrib.auth.models import User from django.urls import reverse import uuid class Category(models.Model): """Model representing an Asset category""" name = models.CharField(max_length=128) def __str__(self): return self.name class Borrower(models.Model): first_name = models.CharField(max_length=64) last_name = models.CharField(max_length=128) associated_user = models.ForeignKey(User, on_delete=models.CASCADE, null=True) def __str__(self): return f'{self.first_name} {self.last_name}' class Asset(models.Model): """Model representing an Asset""" # Unique identifier for an instance of an asset (a barcode of sorts) … -

This is the code for admin.py: from django.contrib import admin # Register your models here. from .models import profiles class profileadmin(admin.Modeladmin): class Meta: model = profiles admin.site.register(profiles, profileadmin) The full error message is this: Unhandled exception in thread started by <function check_errors.<locals>.wrapper at 0x03ED28A0> Traceback (most recent call last): File "C:\Users\roche\AppData\Local\Programs\Python\Python37-32\lib\site-packages\django\utils\autoreload.py", line 225, in wrapper fn(*args, **kwargs) File "C:\Users\roche\AppData\Local\Programs\Python\Python37-32\lib\site-packages\django\core\management\commands\runserver.py", line 109, in inner_run autoreload.raise_last_exception() File "C:\Users\roche\AppData\Local\Programs\Python\Python37-32\lib\site-packages\django\utils\autoreload.py", line 248, in raise_last_exception raise _exception[1] File "C:\Users\roche\AppData\Local\Programs\Python\Python37-32\lib\site-packages\django\core\management\__init__.py", line 337, in execute autoreload.check_errors(django.setup)() File "C:\Users\roche\AppData\Local\Programs\Python\Python37-32\lib\site-packages\django\utils\autoreload.py", line 225, in wrapper fn(*args, **kwargs) File "C:\Users\roche\AppData\Local\Programs\Python\Python37-32\lib\site-packages\django\__init__.py", line 24, in setup apps.populate(settings.INSTALLED_APPS) File "C:\Users\roche\AppData\Local\Programs\Python\Python37-32\lib\site-packages\django\apps\registry.py", line 120, in populate app_config.ready() File "C:\Users\roche\AppData\Local\Programs\Python\Python37-32\lib\site-packages\django\contrib\admin\apps.py", line 24, in ready self.module.autodiscover() File "C:\Users\roche\AppData\Local\Programs\Python\Python37-32\lib\site-packages\django\contrib\admin\__init__.py", line 26, in autodiscover autodiscover_modules('admin', register_to=site) File "C:\Users\roche\AppData\Local\Programs\Python\Python37-32\lib\site-packages\django\utils\module_loading.py", line 47, in autodiscover_modules import_module('%s.%s' % (app_config.name, module_to_search)) File "C:\Users\roche\AppData\Local\Programs\Python\Python37-32\lib\importlib\__init__.py", line 127, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "<frozen importlib._bootstrap>", line 1006, in _gcd_import File "<frozen importlib._bootstrap>", line 983, in _find_and_load File "<frozen importlib._bootstrap>", line 967, in … -

When it comes to the genre I have a field in the model called tags which is a comma separated values. so for example, if the value is 'action, comedy, drama' and someone is looking for a genre of 'comedy' I want them to be able to find it from these tags. Django code: videos = Media.objects.order_by( '-date').filter(is_published=True) if 'genre' in request.GET: genre_tags = request.GET['genre'] if genre_tags: genre_tags = videos.filter(tags=genre_tags) context = { 'medias': paged_movies, 'values': request.GET } return render(request, 'media_files/listing.html', context) HTML code: <select class="filter-genre"> <option value="">All</option> <option {% if values.genre == 'action' %} selected {% endif %} value="action">Action</option> <option {% if values.genre == 'adventure' %} selected {% endif %} value="adventure" >Adventure</option> <option {% if values.genre == 'animations' %} selected {% endif %} value="animations" >Animations</option> <option {% if values.genre == 'crime' %} selected {% endif %} value="crime" >Crime</option> <option {% if values.genre == 'horror' %} selected {% endif %} value="horror" >Horror</option> <option {% if values.genre == 'documentary' %} selected {% endif %} …
