How to create a function for organising objects on the template
I am trying to create a template for a blog landing page. While the politics object is less than four, I want the first for loop to be executed. **political.html {% extends 'index.html' %} {% block content %} {% for politics in politics %} <div class="post-entry-1 col-lg-4 box mx-1"> <a href="single-post.html"><img src="{{politics.image.url}}" alt="" class="post_img"></a> <div class="post-meta"><span class="date">{{politics.category}}</span> <span class="mx-1">&bullet;</span> <span>{{politics.created_at}}</span></div> <h2 class="mb-2"><a href="single-politics.html">{{politics.title}}</a></h2> <span class="author mb-3 d-block">Ole Pundit</span> <p class="mb-4 d-block">{{politics.body|truncatewords:75}}</p> </div> {% if politics > 4 %} {% for politics in politics %} <div class="post-entry-1 border-bottom"> <div class="post-meta"> <span class="date">Culture</span> <span class="mx-1">&bullet;</span> <span>Jul 5th '22</span> </div> <h2 class="mb-2"> <a href="single-post.html">How to Avoid Distraction and Stay Focused During Video Calls? </a> </h2> <span class="author mb-3 d-block">Jenny Wilson</span> </div> {% endfor %} {% endif %} {% endfor %} {% endblock %} But once the count of the political posts exceeds 4 I want the second for loop to be executed. Ideally, the function is supposed to help me organise where the posts appear on the landing page. **view.py from django.shortcuts import render from .models import Post, Politics from django.views.generic import DetailView # Create your views here. def index(request): return render(request, 'index.html') def allposts(request): posts = Post.objects.all() return render(request, 'allposts.html', {'posts':posts}) def … -
UWSGI - Different Flask UPLOAD_FOLDER for each worker/process running
Is it possible to have a different UPLOAD_FOLDER for every UWSGI worker? app-python | WSGI app 0 (mountpoint='') ready in 16 seconds on interpreter 0x558d526ffae0 pid: 8 (default app) app-python | >>> Files will be uploaded in: /app-python/upload app-python | WSGI app 0 (mountpoint='') ready in 16 seconds on interpreter 0x558d526ffae0 pid: 10 (default app) app-python | >>> Files will be uploaded in: /app-python/upload app-python | WSGI app 0 (mountpoint='') ready in 16 seconds on interpreter 0x558d526ffae0 pid: 9 (default app) app-python | >>> Files will be uploaded in: /app-python/upload app-python | WSGI app 0 (mountpoint='') ready in 16 seconds on interpreter 0x558d526ffae0 pid: 1 (default app) To explain further, I would like each worker to have a separate upload folder, app-python/upload1 , app-python/upload2 and so on. The reason I'm asking for this request is I think this is causing some files to be overwritten and the output I get from the app doesn't make any sense, and the only logical reason is that the workers are overwriting each other's files. Please let me know if I'm right, and if I am, please tell me if I can set a different upload folder for each worker. I'm also going to … -
How do I increase database variable by 1 using put method is JS?
I am making a web app similar to twitter that allows users to like a post. In order to make changes to the database, I created an API that allows one to use GET, PUT, or POST methods in order to access or make changes to the database. I am using a Django Framework database and am using javascript to send fetch requests to the API. My problem is that I am trying to use a put method to set the "likes" attribute of a post equal to 1 more than the previous number of likes the post had. I don't know how to do this. Below is my javascript function that runs once a post is liked. I tried to access the number of likes a post has and set it equal to a variable. However, that is not working. function likePost(postID){ var postLikes; fetch('/posts/' + postID) .then(response => response.json()) .then(post => { postlikes = post.likes }) fetch('/posts/'+postID, { method: 'PUT', body: JSON.stringify({ likes: postLikes++, liked: true }) }) console.log(postLikes) } For some reason, the console.log returns NotaNumber, meaning that postlikes is not set equal to post.likes and is never instantiated. Thus, "likes" is never set equal to postLikes++ … -
how to make the same button in a django html page turn on different LEDs

Django test with fixtures gives ForeignKeyViolation or IntegrityError
I am trying to write test cases for the Django RestAPI that we have but I have an issue with the fixtures loading. Everything works correctly when I have only one TestCase but when I add a second TestCase in a second django app I get django.db.utils.IntegrityError. My original intention was to create a general TestCase where I set up the most used objects in the setUpTestData function and make the other tests inherit from that one. Things I have tried: Using APITestCase from rest_framework and TestCase from django Not using inheritance, and having both files using TestCase from django Using setUp method instead of setUpTestData Using call_command from django.core.management in the setUpTestData method instead of creating the fixtures in each class in the class variable Declaring the fixtures only in the TestCase that is executed first (this makes the other TestCase have an empty DB, so it it clear that for each TestCase info is recreated) Changed the order of the files in the fixtures variable When I comment one of the test files the other works and vice-versa. When I used the call_command with verbose=2, the fixtures in the first file executed work perfectly, and it breaks just … -
How to I get the path to a file with Django?
I am currently using Django's forms to create a FileField that allows the user to upload a file. However, after I select the file, it creates an object of type django.core.files.uploadedfile.InMemoryUploadedFile, which is a copy of the original file. How would I go about to get the original path of this file so I can either modify or replace it? # forms.py class UploadFile(forms.Form): file = forms.FileField(label="Select File: ", required=True) # views.py def get_path(response): context = {} if response.method == "POST": form = UploadFile(response.FILES) if form.is_valid(): file = form.cleaned_data["file"] # Is there a way to get the original file path or should I just not use FileField? print("The File Path Here") -

How to test two django forms that are in the same view
So I have a view that handles two different forms in the same POST request. Previously the testing was easy because i had only one form so it would be something like: def test_post_success(self): response = self.client.post("/books/add/", data={"title": "Dombey and Son"}) self.assertEqual(response.status_code, HTTPStatus.FOUND) self.assertEqual(response["Location"], "/books/") If i have a second form with a 'prefix' how would i construct the data object of the request. Im thinking of: form_1_data = {foo} form_2_data = {bar} response = self.client.post("/books/add/", data={form_1_data, form_2_data) But it clearly does not work -
Trigger events in dropdowns using "Select2" library from Django Forms
I'm using the "select2" library to work with model-bound, related and dependent dropdowns and I want to handle various events like: change, click, blur and focus; however, only the change event is executed, but, when I use a regular dropdown, all four events work properly. How can I handle the dropdown events, noted above, in conjunction with the "select2" library? The idea is populate "Office" drop-down with previous selection of "Corporation" and "Division" drop-down, and those dropdowns obey the four events. dropdowns: coporation > division > office # forms.py class NewEmployeeForm(forms.ModelForm): class Meta: model = Employee fields = '__all__' widgets = { 'coporation': forms.Select( attrs={ 'class': 'form-control select2', 'style': 'width: 100%', }, ), 'division': forms.Select( attrs={ 'class': 'form-control select2', 'style': 'width: 100%', }, ), 'office': forms.Select( attrs={ 'class': 'form-control select2', 'style': 'width: 100%', }, ), # template.html <!-- form --> <form method="post" id="empleado_form" data_offices_url="{% url 'employees:ajax_get_offices' %}" novalidate> <fieldset> {% csrf_token %} <div class="col-sm-4 form-group {% if form.corporation.errors %}has-error{% endif %}"> {{ form.corporation.label }} {{ form.corporation }} <div class="text-danger"> {{ form.corporation.errors }} </div> </div> <div class="col-sm-4 form-group {% if form.division.errors %}has-error{% endif %}"> {{ form.division.label }} {{ form.division }} <div class="text-danger"> {{ form.division.errors }} </div> </div> ... </form> <script> $(function() … -

How to add multiple rows of data to a single column of an existing instance of a model? Django
view linked to a form, to a model. I'd like to make it so that when I update one of those fields (current-command). It adds that data to another field (Executed_Commands).

What limits are there on the number of fields on a Django model?
What practical limits are there on the number of fields a Django model can have? I'm thinking both at the code level, and at the database level (particularly both Sqlite and Postgres). If the specific version of anything is required then let's say we are talking about the latest LTS version (or nearest equivalent) of everything running on Ubuntu Server. -
Display index of each item of a sorted list in view Django DRF
I am developing an application with a Django backend and the DRF framework for my api. At a given url I would like to display the index (the rank) of each user once the list is sorted on my view.

This my uwsgi.ini: [uwsgi] chdir = ./src http = :8000 enable-threads = true #harakiri = 300 master = true module = config.wsgi:application #processes = $(UWSGI_PROCESSES) #threads = $(UWSGI_THREADS) #max-worker-lifetime = $(UWSGI_MAX_WORKER_LIFE) workers = 32 thunder-lock = true vacuum = true workdir = ./src add-header = Connection: Keep-Alive http-keepalive = 65000 max-requests = 50000 max-requests-delta = 10000 max-worker-lifetime = 360000000000 ; Restart workers after this many seconds reload-on-rss = 2048 ; Restart workers after this much resident memory worker-reload-mercy = 60 ; How long to wait before forcefully killing workers # Increment the timeout to reach the target app. # http-timeout = 60 lazy-apps = true single-interpreter = true ignore-sigpipe = true ignore-write-errors = true http-auto-chunked = true disable-write-exception = true This is the settings.py for my app: """ Django settings for config project.

Problems with if statement and _set.all Django
I tried two ways to make a filter in the django template, but neither worked for me, I don't know if I'm sending the arguments wrong or if I'm missing something. I need to show a part of the template only if the 'user' is also part of the 'teacher' model (teacher has FK to User). My template: {% if user in user.teacher_set.all %} <tr> <td class="table-text typo-grey"><label class="float-left">Rol</label></td> <td class="rol centered"> <div class="ui input"> <select type="text" id="id_{{form.rol.html_name}}" name="{{form.rol.html_name}}"> {% for rol in form.rol.field.queryset %} <option value="{{rol.pk}}">{{rol.name}}</option> {% endfor %} </select> </div> </td> </tr> {% endif %} This brings a empty queryset. I also tried creating a templatetag: @register.simple_tag def get_teachers_user(user): teacheruser = models.Teacher.objects.filter( user=user, active=True ) return {'teacheruser': teacheruser.latest('pk')} And then in template: {% get_teachers_user user as teacher_user %} {% if not user in teacher_user.teacheruser %} <tr> <td class="table-text typo-grey"><label class="float-left">Rol {{teacher_user.teacheruser}}</label></td> <td class="rol centered"> <div class="ui input"> <select type="text" id="id_{{form.rol.html_name}}" name="{{form.rol.html_name}}"> {% for rol in form.rol.field.queryset %} <option value="{{rol.pk}}">{{rol.name}}</option> {% endfor %} </select> </div> </td> </tr> {% endif %} Doesn't work either. Please if you have any advice please comment, also this template is for a FormView. Thanks -
