Django Object Not created after form submission
Hi I am using Django and Ajax for users create 'Posts' on their website. However, After the form submission the post is not shown. I do not know what's causing this as I see no errors. My views for the homepage and creating a post is: @login_required def home(request): posts = Post.objects.all() context = {'posts':posts} return render(request, 'home/homepage/home.html', context) @login_required def post_create(request): data = dict() if request.method == 'POST': form = PostForm(request.POST) if form.is_valid(): form.save() data['form_is_valid'] = True posts = Post.objects.all() data['posts'] = render_to_string('home/posts/home_post.html',{'posts':posts}) else: data['form_is_valid'] = False else: form = PostForm context = { 'form':form } data['html_form'] = render_to_string('home/posts/post_create.html',context,request=request) return JsonResponse(data) my post_create.html: {% load crispy_forms_tags %} <form method="POST" data-url="{% url 'home:post-create' %}" class="post-create-form"> {% csrf_token %} <div class="modal-header"> <h5 class="modal-title" >Create a Post</h5> <button type="button" class="close" data-dismiss="modal" aria-label="Close"> <span aria-hidden="true">&times;</span> </button> </div> <div class="modal-body"> {{ form|crispy }} </div> <div class="modal-footer"> <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button> <button type="submit" class="btn btn-primary">Post</button> </div> </form> My home.html: {% extends "home/homepage/base.html" %} {% load crispy_forms_tags %} {% load static %} {% block javascript %} <script src="{% static 'js/post.js' %}"></script> {% endblock javascript %} {% block content %} <div class="card"> <div class="card-body"> <div class="media mb-0 align-items-center"> <img class="img-create-post rounded-circle my-0 mr-3" style="width: 50px;height: 50px;" … -

Django-taggit tag value retrieval and formatting failing
I am trying to implement a tagging process for profiles so you can add your hobbies for example. I have chosen django-taggit as it seemed quite simple and does what I need it to, plus don't really know how to do it myself from scratch. I have managed to make it work to some extent but I am having issues with 3 things: Not really sure what's the best way to control the form field for these tags as I generate the form automatically with widget adjustments in meta function of the form, but it might work fine after resolving the below two issues. When there is no data for the field hobbies (tags) the field gets populated with a single tag of value "[]" as per below image. When I add a tag of "music" and submit the form after I reload the page I get this "[]" as per image. I assumed this will be dealt with by the library, but I cannot see another similar scenario online. My model is: class UserProfile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) hobbies = TaggableManager() My form is: class UserProfileForm(forms.ModelForm): class Meta: model = UserProfile fields = ['hobbies',] def __init__(self, *args, **kwargs): super(UserProfileForm, … -

Changing the data type of values in the Django model
I have data which is loaded into a dataframe. This dataframe then needs to be saved to a django model. The major problem is that some data which should go into IntegerField or FloatField are empty strings "". On the other side, some data which should be saved into a CharField is represented as np.nan. This leads to the following errors: ValueError: Field 'position_lat' expected a number but got nan. If I replace the np.nan with an empty string, using data[database]["df"].replace(np.nan, "", regex = True, inplace = True), I end up with the following error: ValueError: Field 'position_lat' expected a number but got ''. So what I would like to do, is to check in the model whether a FloatField or IntegerField gets either np.nan or an empty string and replace it with an empty value. The same for CharField, which should convert integers (if applicable) to strings or np.nan to an empty string. How could this be implemented? Using ModelManager or customized fields? Or any better approaches? Sorting the CSV files out is not an option. import pandas as pd import numpy as np from .models import Record my_dataframe = pd.read_csv("data.csv") record = Record entries = [] for e … -
What is the clean way to integrate another service to django
I have a Django 3 application, using an LDAP service class, like this : class LDAPService: def init(self, host: str, user: str, password: str, ssl: bool = True): ... def bind(): # The connection is done here, __init__ just sets values .... def create_ou(base: str, ou_name: str): .... Where (or when) should I initialize the service to use it in views ? The bind step takes about 2 seconds to apply, I can not do it on every request. How can I keep an instance of this class shared, and not done every single time ? I may have a solution using singleton, and/or initializing it in like settings files, but i think there is a better way to do it. I know in production, there may be multiple workers, so multiple instances, but i am ok with it. Another question: How can everything above be done, with connections credentials from a database model (so not at django startup, but at anytime) I am totally new to the django ecosystem, the things i have found about a service layer were all about django models. I think the LDAP connection itself should not be there, only the CRUD methods, but i … -

Django 3.0: Page not found at /polls/1/{url 'polls:vote' question.id}
I'm stucked at Django's official tutorial (see Writing your first Django app, part 4). I get the following error: In this Django project, inside the poll app I'm making, we're supposed to make a vote() view in views.py which should process the POST request data of the poll and redirect us to the results() view (there's no template for the vote()view, it's just in charge of processing the data we send through the poll).

How to reach and add new row to web server database which made in Django framework?

How to make a background script with Django which check regularly on an InfluxDB database?
Context I'm designing a vizualisation application (like Grafana) with Django. The data come from multiples sensors (temperature etc..) and are stored in an InfluxDB database. I'd like to have a front-end where the user can see all his past data. To achieve this i plan to fetch the data in python with the InfluxDB API and plot them in Javascript (with plotly.js for example) when the user click a button or something similar. The really big trend in IoT is to be able to receive an alert when a data, for example temperature, reachs a certain threshold. So i'd like to give the user the opportunity to set custom threshold and to receive mail alert for example when the criteria is met. Problem In a Django environment, python code is executed once you reach a certain ressource, so how i can create a Python code which would run complelty in background (the user can close his browser), and checks periodically if a certain field in the database goes above a certain threshold ? Moreover this threshold needs to be updated dynamically if the user wants to change it. Solution envisaged When the user sets a threshold, Django writes in a … -

It's all working, but I want to filter the horses so only the horses that are connected to the current User will show. file: models.py from django.contrib.auth.models import User class Horse(models.Model): name = ... ... owner = models.ForeignKey('Rider') class Rider(models.Model): name = ... ... user = models.ForeignKey(User) So when I render my html-page, I want to filter the horses accordingly: file: views.py from .models import Horse def Horses(request): horses = { 'horses': Horse.objects.filter( ??????? ) } return render(request, 'stable/horses.html', horses) So if I'm logged in as "Admin", how do I pass this into the filter, so all horses that have a relationship with a rider that have a relationship with this user will show? Seems to be something different when referring to a ForeignKey-object instead of just an attribute that I can't figure out. -
is it possible to run celery, celery beat and celery flower from one command?
I have installed celery, celery beat and celery flower all on one container, im using rabbitmq as the broker and Redis as the backend. settings below: app = Celery('itapp', broker='amqp://lcl_rabbit:5672', backend='redis://lcl_redis:6379', include=['itapp.tasks']) im trying to run all three of these on startup of one container, I have the command below, but it looks like its only running celery and flower and skipping beat. as I aren't seeing any scheduled tasks run celery flower -A itapp -l info --beat --scheduler django_celery_beat.schedulers:DatabaseScheduler --port=5555 is this not possible or not avisable? ideally im just looking to see the results of the tasks that have been scheduled with beat, I can see their being run as the last run timestamp is incrementing and I can see them being sent to a worker in the terminal. but not sure where I can see all the results and came across flower... Thanks
