Adding the search button and filter button to a single button in Django
Here I am trying to activate two functions with one button. How would it be to write the search button and filter system in a single function, as shown in the examples? I used the django filters framework for the filter. example image This is my views.py file def job_list(request): jobs = Job.objects.all().order_by('-date') locations = Location.objects.all() categories = Category.objects.all() jobtypes = JobType.objects.all() experiences = Experience.objects.all() qualifications = Qualification.objects.all() genders = Gender.objects.all() #filter start my_filter = JobFilter(request.GET, queryset=jobs) jobs = my_filter.qs #filter done context = { 'jobs': jobs, 'categories': categories, 'locations': locations, 'jobtypes': jobtypes, 'experiences': experiences, 'qualifications': qualifications, 'genders': genders, 'my_filter': my_filter, } return render(request, 'jobs.html', context) Here is my filters.py file import django_filters from . models import Job class JobFilter(django_filters.FilterSet): class Meta: model = Job fields = ['location', 'category', 'experience', 'qualification', 'jobtype', 'gender'] this is the search function I also defined a URL to the search function in url.py. def search(request): search_query = '' if request.GET.get('search'): search_query = request.GET.get('search') """aynı şeyleri göstermez... distinct""" jobs = Job.objects.distinct().filter( Q(name__icontains = search_query) | Q(description__icontains = search_query) | Q(category__name__icontains = search_query) ) categories = Category.objects.all() context = { 'jobs': jobs, 'categories': categories, 'search_query': search_query, } return render(request, 'jobs.html', context) I tried many functions but … -
DJANGO template variable not rendering in HTML
I'm working on a Django project, and I'm having trouble getting a variable to render in my HTML template. I have a view that passes a dictionary containing some data to my template, and I want to display a specific value in the HTML. Here's a simplified version of my view: def my_view(request): data = {'user_name': 'John Doe', 'age': 25} return render(request, 'my_template.html', {'data': data}) n my_template.html, I'm trying to display the user's name like this: html <!DOCTYPE html> <html> <head> <title>My Template</title> </head> <body> <h1>Welcome, {{ data.user_name }}!</h1> </body> </html> However, when I load the page, the user's name doesn't render. It just shows "Welcome, !" without the actual name. What am I doing wrong? Any help would be appreciated! yaml --- In this example, the user is facing an issue with rendering a Django template variable (`data.user_name`) in their HTML. They provide relevant code snippets from both the view and the template, explain the problem they are encountering (the variable not rendering), and express a need for assistance.

Dynamic StatesGroup on aiogram 3.1.1
Good afternoon everyone. Curf work in a company developing telegram bots for businesses, the main stack is Django / Aiogram 3.1.1. At the moment I am faced with one difficult task and I would like to ask others about the possibility of its implementation. In short, the task is this: The database contains a table with questionnaires (field name, field question) and a table associated with the name of the question: the type of question validation (validation of number, name, mailbox, etc.), as well as a table with the user associated with the answer to the questionnaire. questionnaires and types DBdiagram My task is to create a kind of processor for filling out questions from these questionnaires. The difficulty is that, in fact, I could create a StateGroup and write it like this: class QuestionsStates(StatesGroup): email = State() phone_number = State() full_name = State() # . . .` Next, I would create handlers for each state, and after receiving and validating the data in the last state, the handlers would send the data to the database and that’s all. @router.message(QuestionsStates.last_state) async def send_data_to_backend(message: Message, state: FSMContext): user_answers = await state.get_data() # user_answer.get('') # send all data with user_id to backend … -

Postgresql causing memory problems in django
I recently started getting this error Python(43052,0x7000021e4000) malloc: *** error for object 0x1: pointer being freed was not allocated Python(43052,0x7000021e4000) malloc: *** set a breakpoint in malloc_error_break to debug on launching my local Django server. I know Python has nothing to do with malloc which is a C library, and this kind of leaves me powerless, as I don't really know C... Shouldn't python do all this automatically? I figured that when I disconnect my PostgreSQL database (i.e. just comment out the DATABASES= ... ) in my settings.py the error goes away. It of course doesn't run my project as it relies on the database, but at least the error happens within the app. If I bring back the DATABASES, Django doesn't even start the app, as the error happens right on server startup and is only logged in the console. What's interesting is that the very same version of the program, but deployed to my production server on Azure works perfectly. -
Django: launch a django-independent python script
I have a Django + script launch problem. For context: I'm creating a website in Django that uses a database that isn't huge at the moment, but will grow over time. I've created my own administration according to my needs. A requirement is a retroactive action on the entire database. In order not to affect the website, the operation is carried out via another python script (which is not in views.py). The script lasts a minute and if I launch it from views.py, the site "freezes" on my side and I can no longer browse. That's why I've decided to create a separate script. My problem is that I need Django to launch this script without impacting the front-end, i.e. if I click on the script launch button on the front-end, I can continue browsing. I tried using subprocess : subprocess.run(['python3', '/home/ec2-user/scripts/database_cleaning.py']) Fun fact: the site seems frozen (I've got a spinning wheel on the tab name), but I can navigate and the script seems to work. On the other hand, it sometimes causes bugs when I'm browsing: a psycopg2 transaction doesn't close and the site is "KO'd" until I kill the process directly on PostgreSQL. So it seems that … -
Styling a NavBar in Django Python API

Send data by href (html) and get it with request function (django)
I have a html page where I looping on model fields. Html is: {% for problem in problems_list %} <p> {{ problem.id }} - {{ problem.incident_date }} - {{ problem.incident_specs }} - {{ problem.incident_location }} - {{ problem.incident_reason }} {% for action in actions_list %} {% if action.action_incident_id_id == problem.id %} <form method="post"> <input hidden name='problem_id' value="{{ problem.id }} "> <a class="btn btn-primary" type="submit" href="{% url 'ex_action' %}"> Button </a> <!-- action="{% url 'ex_action' %}"--> </form> {% endif %} {% endfor %} </p> {% endfor %} And here is a ex_action function: def ex_action(request): return render(request, 'problems/ex_action.html', {'actions_list': actions_list}) It works well, but I need to pass a problem.id from for loop into ex_action, and I don't know how to do it. I tried some constructions like href="{% url 'ex_action'?=problem_id=problem.id %}" and get it by something like request.GET.get('problem_id') or request.GET['problem_id'], but got TemplateSyntaxError on html, none as result on django code or MultiValueDictKeyError. Read a lot of docs\issues, and find what people use ajax\js to solve it, but I don't know how. Please help. -
Getting 403 MissingAuthenticationTokenException with OPTIONS Requests in AWS API Gateway
I am building a web app using React, Django and AWS. I have a Rest API on API Gateway that is giving a 403 "MissingAuthenticationTokenException" that seems to be specifically on OPTIONS requests. I am quite confused as I haven't set any authentication on the API and even have included an API key to try and fix it. This is what the error looks like on the console: Console Error: Console Error And when I looked at the network I see that it is caused by a 403 error: Preflight Error: Preflight Error Cors Error: Cors Error Network Error: Network Error On my react front-end I call the API on a button press: const formData = new FormData(); formData.append("image", selectedFile); try { await axios({ method: "put", url: "https://my-api.execute-api.eu-west-2.amazonaws.com/dev/photos/", data: formData, headers: { "Content-Type": "multipart/form-data", "x-api-key": "abc123" } }); } catch (error) { console.error(error); } And on my Django views.py it looks like this: def upload_image(request, bucket, filename): if request.method == 'OPTIONS': # Respond to preflight request with a 200 OK response = Response({'message': 'Preflight request successful'}) response['Access-Control-Allow-Origin'] = '*' # Update with your specific origin(s) response['Access-Control-Allow-Methods'] = 'PUT, OPTIONS' response['Access-Control-Allow-Headers'] = 'Content-Type, X-Amz-Date, Authorization, X-Api-Key, X-Amz-Security-Token' response.statusCode = 200 # … -

Why is my global dictionary value is changed in different views in Django?
In my Django app I have a global dictionary that stores some instances of a Class. Valu of this dictionary is being changed by one of my Django views. Then I use that global dictionary inside my other views. The problem is, in production, when I access this global dictionary in other views, value of it is changed (global dictionary changes to its initial value). I deployed Django app on Ubuntu server using Gunicorn and Nginx. Here is the scenario: my_global_dict = {} # This is the global dictionary with initial value of empty dict def view1(request): my_global_dict["key0"] = myClass() # Adding my class instance to the global dict ... def view2(request): print(my_global_dict) # Prints: {}. The global dict is empty in this view and others ... I emphasize that there is no problem in the process in the development environment. Also it works with Apache and IIS with ease. The problem I'm facing is after deploying on Gunicorn and Nginx. Thanks in advance! -
django-hitcount not recording ip adresses in hit
So, i'm using django-hitcount to keep track of user hits in my application. the application uses uuid as primary key for id of the books. so, i did a little modification to the django-hitcount code from here. the exact new version isnt compatible so i used it upto a specific commit. the forked repo is here. I only changed the object_pk on the hitcountbase model to uuid and removed the previous id which was used as a primary key. You can check the commit in here Running it on my project it is not recording the ip addresses of the hits and putting in the default 10.0.0.1 ip address on every data it tracks. Did I miss to change something while making it work with uuid? -
Django Convert image format to .webp (ResizedImageField)
I'm trying to use ResizedImageField instead of ImageField in Django to convert image files to .webp format. Most of the images work fine, but I'm having an issue with raw images taken by my iPhone.

How do I run code once immediately after an object is created?
I'm working on an internal tool built using Django. Part of what we're doing with this tool is digitizing content from old PDFs. The PDFs have been through some kind of OCR process, but it has left them with frequent doubled or tripled spaces and hard returns at the end of every line. We're using this text to create database objects in Django's built-in admin. Imagine I have a data model like this: import re from django.db import models from django.db.models import CharField, TextField class Widget(models.Model): name = CharField() description = TextField() def fix_description(self): self.description = re.sub(r"\s+", " ", self.description) self.description = re.sub(r"\\n", "\n", self.description) self.description = re.sub(r" *\n *", "\n", self.description) Most of the time, the text in description will be a single paragraph. Occasionally it should contain actual line breaks, which I'd like to denote by typing \n into the description field in Django admin when creating the object. The fix_description method cleans up unintended whitespace exactly as we'd like, and keeps line breaks entered manually. What I'd like is to have fix_description run exactly once when the object is created through the Admin form, and then never again. I don't want to worry about having this code … -

First I am extracting the model name of the M2M field from the value I get through the loop. Then I am trying to add data to m2m table, but this AttributeError: 'ProductAttributes' object has no attribute 'm2m_model' is coming. attribute = ProductAttributes.objects.get(pk=pk) for key in common_keys: if initial[key] != new_data[key]: # Getting m2m model in lower case m2m_model = apps.get_model(app_label=app, model_name=key)._meta.model_name attribute.m2m_model.add(new_data[key]) Here's the problem attribute.m2m_model.add(new_data[key]) If I directly name the field then it works fine like below: attribute.color.add(new_data[key]) attribute.ram.add(new_data[key]) I want to make it dynamic. Here is my model: class ProductAttributes(models.Model): color = models.ManyToManyField('Color') band_color = models.ManyToManyField('BandColor') ram = models.ManyToManyField('RAM') vram = models.ManyToManyField('VRAM') Thanks in advance, any help would be much appreciated. -
Fuzz-testing Django application with atheris
I'm running my Django-project: cd PycharmProjects/Autopark source venv/bin/activate python3 manage.py runserver This is insides of project's wsgi.py: import os from django.core.wsgi import get_wsgi_application os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'autopark.settings') application = get_wsgi_application() After that I open another tab of my terminal (I'm using Linux Mint) and start my fuzz-test script via the same venv: source venv/bin/activate python3 fuzz_test1.py That's first few strings from that file: import os import django django.setup() from django.test import Client client = Client() And I have an error at django.setup(): Traceback (most recent call last): File "/home/paberu/PycharmProjects/Autopark/fuzz_test1.py", line 4, in <module> django.setup() File "/home/paberu/PycharmProjects/Autopark/venv/lib/python3.10/site-packages/django/__init__.py", line 19, in setup configure_logging(settings.LOGGING_CONFIG, settings.LOGGING) File "/home/paberu/PycharmProjects/Autopark/venv/lib/python3.10/site-packages/django/conf/__init__.py", line 92, in __getattr__ self._setup(name) File "/home/paberu/PycharmProjects/Autopark/venv/lib/python3.10/site-packages/django/conf/__init__.py", line 72, in _setup raise ImproperlyConfigured( django.core.exceptions.ImproperlyConfigured: Requested setting LOGGING_CONFIG, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings. I don't have any idea of what am I doing wrong. Can you help me get rid of that error? -
mysql: how to resolve duplicate key errot
My django project has a migration that creates a foreign key on a table. When the migrate command is executed, I receive a stacktrace with error : MySQLdb._exceptions.OperationalError: (1061, "Duplicate key name "..." I located the key in table_constraints and in table_constraints_extensions. It doesn't appear to be in any other constraint table. There is one instance of the same key in each table. The foreign key was created, and actually works, but the migration fails to complete due to duplicate keys. I'm just not sure exactly where the duplication is because the FK constraint appears once in each of the tables mentioned above. My project can function without doing anything further, but the migration process will be broken until I fix this in the db. How and where do I fix this problem? delete from table_constratins ... alter table projects_project drop constraint ...
