jQuery Datatables rendered with django ordering not working
I can't seem to get this table to order on click. The app is retrieving a table from Django and rendering it successfully. But when I go ahead and click the arrows at the top of the table columns, a box says 'processing' but no reordering happens. When I disable serverSide programmatically so that it should only happen the first time, the ajax call happens anyway. $(document).ready( function () { $.fn.dataTable.ext.errMode = 'throw'; var table = $('#{{ grid_id }}').DataTable({ "paging": {{paging}} ,"searching": false ,"info": true ,"stateSave": false ,"orderable": true ,"ordering": true ,"processing": true ,"serverSide": true {% if ajax_url is not None %} ,"ajax": { /* "type": "POST", */ "url": "{{ ajax_url }}", "dataSrc": "results", "data": function (d) { d.customParam = "custom"; } }{% endif %}{% if column_list is not None %} ,"columns": [ {% for col in column_list %} { "title":"{{ col.title }}", "data": "{{ col.data }}" {% if col.href is not None %}, fnCreatedCell: function (nTd, sData, oData, iRow, iCol) { $(nTd).html("<a href='{{col.href}}"+oData.{{ col.href_data_attr }}+"'>"+oData.{{ col.data }}+"</a>");}{% endif %} },{% endfor %} ] {% endif %} }); }); -
DJANGO. form not working, button action is null
I am working on the checkout for an ecommerce site and everything is set but the form to choose the shipping and billing addresses before filling the credit card info. I have no clue why the form is not working, its not passing any data nor performing any action. The 3 data fields that I am passing are saved to an existing order model which already contains info like price, products, etc. The order model works perfectly fine as well as everything else in the site. This is the form in my template: <form method="POST" name="check_address"> {% csrf_token %} <div> <h4 class="mb-3">Dirección de envío</h4> {% if shipping_addresses %} <div class="list-group form-group mb-2"> {% for address in shipping_addresses %} <a class="list-group-item list-group-item-action flex-column align-items-start"> <div class="d-flex w-100 justify-content-between"> {% if request.user.defaultaddresses.shipping.id == address.id %} <input type='radio' name="shipping_address" form="check_address" value="{{address.id}}" checked> {% else %} <input type='radio' name="shipping_address" form="check_address" value="{{address.id}}"> {% endif %} <h5 class="mb-1">Dirección</h5> </div> <p class="mb-1">{{address.street_address}}{% if address.apartment_address %} {{address.apartment_address}}{% endif %}</p> <small class="text-muted">{{address.get_city}}</small> </a> {% endfor %} </div> <div id="collapseTwo" class="collapse mt-3 mb-3"> <h5 class="mb-3">Nueva dirección de envío</h5> {% include 'snippets/addressform.html' %} </div> {% else %} {% if address_form %} {% include 'snippets/addressform.html' %} {% endif %} {% endif %} … -

Is it possible to let a user choose how many fields to be filled?
I am planning to do an application with Django where the user shall inform how many columns and which data types will be submitted through a CSV file. I know I can define, in the views.py, formats, create MultiValueFields, and have the CSV content into a JSONField in the database. But the ideal would have to have individual tables for each informed CSV, in the database, because I will need to access specific parts of that data many times and I fear eventually extracting a lot of JSON dictionaries and processing the whole data chunck to pick parts of it will not scale well. As for what I know, a Model you write on models.py, is a role model for Django to create specific columns on the database table, through makemigrations and migrate commands. As it is a pretty static and reliable way on functioning, it really is bugging me if it is not possible to dynamically allocate data. I have already thought on two ways of doing it, while still using Django: To create a model with a lot of ModelFields, each of them not being required to be filled and NULL as default value; The JSONField solution.

Django - Postgres Full Text Search customization word segmentation
I'm trying to implement full-text search functionality for my website. We decided to go for PostgreSQL full-text search on first iterations because of it's simplicity to setup. I found out that Postgres doesn't have good support for our website users' language. Thus the word segmentation came with Postgres will not work. I want to use the tsquery generated by our own parser instead of letting the Postgres function do that for me. Please tell me if there's a way to do it by Django builtin ORM. This is the way Postgres does a full-text search without gin index. SELECT title FROM pgweb WHERE to_tsvector('english', body) @@ to_tsquery('english', 'friend'); If Django ORM cannot achieve the desired functionality, then is it possible to search instead like this by using a custom query and custom parser hosted in my backend? SELECT title FROM pgweb WHERE my_own_parsed_tsvector @@ my_own_parsed_tsquery; Further I'd like to know if building a GIN index with custom parsers are possible. I'd really appreciate it for any possible help. -
Django: Validating POST data from a manually built form
I've built a page that shows a list of all available products (Item) and allows user to add a product to their order, as well as adjust the quantity. My three models: Order Item OrderItem where Item is a model to create products for sale. OrderItem is created once an Item is added to an Order. class Order(models.Model): user = models.ForeignKey(...) class Item(models.Model): title = models.CharField() description = models.TextField() class OrderItem(models.Model): item = models.ForeignKey(Item) quantity = models.IntegerField() order = models.ForeignKey(Order, related_name='items') The page that lists all of the products is essentially a ListView on Item. However, I've annotated the Item.object to include order_item quantity (if it exists): views.py: order_item = request.order.items.filter(item=OuterRef('pk')) items = Item.objects.all().annotate(order_quantity=Subquery(order_item.values('quantity'))) context = { 'items': items } return render(self.request, 'services.html', context) In services.html, I loop through items, and display the title and description, as well as build a form with input box for quantity: <form method="post"> {% for item in items %} {{ item.title }} {{ item.description }} <span onclick="document.querySelector('#item-{{ item.pk }}-quantity').stepDown()" class="minus">—</span> <input style="text-align: center; width: 3rem" class="quantity" min="0" name="{{ item.pk }}" value="{% if item.order_quantity %}{{ item.order_quantity }}{% else %}0{% endif %}" type="number" id="item-{{ item.pk }}-quantity"> <span onclick="document.querySelector('#item-{{ item.pk }}-quantity').stepUp()" class="plus">+</span> </form> Now, in my view, … -
how run celery worker as a part of django management command?
I am totally new with celery + django, so here is the question: I know that according to celery documentation to make it running, we need to create a celery.py file, and then start a worker as an independent process like that: celery -A proj worker -l info I wonder if there is an option to run it through a custom management command instead of running it this way. The reason for this is that I use a third-party django-based platform (oTree), which modifies settings.py before starting, which means that I can't do in celery.py the way they recommend: os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'proj.settings') So if somehow I would manage to start celery from within django (like a custom management command), the environment this process would run in, would already get modified settings, which would work. Any ideas how to do that? -
Iterating through dictionary items from Django html template
I'm new to Django and like to learn the basics first. I was looking for an answer about iterating dictionary from a template. There are couple of questions similar to mine but no one mention the way that is the simplest and works. However, as I don't have enough reputation I can't comment. Therefor, I created this one here as I really want it to be seen. Example: let's say we create our dictionary in the def inside views.py as below: def home_page(request): person = {"name": "Saif", "Phone": 111111111} context = {"person": person.items} return render(request, 'home.html', context) Then in home.html for example, we can iterate easily: {% block body %} {% for key, value in person %} <p>{{ key }}:{{ value }}</p> {% endfor %} {% endblock %} I tried other answers but all didn't work and this one works for me.

Django Rest Framework: How to ignore 'unique' primary key constraint when validating a serializer?
I am attempting to store large amounts of transit data in a PostgreSQL database, where a client uploads multiple records at a time (in the tens of thousands). I only want one arrival time per stop, per route, per trip and the unique identifier for that stop, route, and trip is the primary key for my table (and a foreign key in a different table). I am trying use Django's update_or_create in my serializer to either create the entry for that arrival time or update the arrival time with the latest data if it already exists. Unfortunately, while calling is_valid() on my serializer, it identifies that the repeat records violate the uniqueness constraint of the primary keys (which makes sense), giving me this error message: 'real_id': [ErrorDetail(string='actual with this real id already exists.', code='unique')] I want to override this behavior since if the primary key isn't unique it will just update the entry. I have already tried looping over and removing validators like so: def run_validators(self, value): for validator in self.validators: self.validators.remove(validator) super(ActualSerializer, self).run_validators(value) I have also tried removing all validators using the extra_kwargs field of my serializer Meta class like so: extra_kwargs = { 'name': {'validators': []} } I … -

Django Template not rendering mission information
I'm trying to render some information in the template but it isn't showing on even though I think I implemented it right. I'm working on my consultant dashboard (consultant is a user type) My template : <div class="form-group"> {% csrf_token %} <label>Mission </label> <select class="form-control" name="mission" id="mission"> {% for mission in mission %} <option value="{{ mission.id }}">{{ mission.mission_name }}</option> {% endfor %} </select> </div> models.py: class Mission(models.Model): id=models.AutoField(primary_key=True) mission_name=models.CharField(max_length=255) client_id=models.ForeignKey(Client,on_delete=models.CASCADE,default=1) consultant_id=models.ForeignKey(Consultant,on_delete=models.CASCADE) created_at=models.DateTimeField(auto_now_add=True) updated_at=models.DateTimeField(auto_now_add=True) objects=models.Manager() My view: def staff_take_attendance(request): mission=Mission.objects.filter(consultant_id=request.user.id) return render(request,"staff_template/staff_take_attendance.html",{"mission":mission}) -
Django celery unable to set custom scheduler as DatabaseScheduler
I have a Django project setup and working. Celery is also working i am able to start worker as well as celery beat. Trying to use django_celery_beat and set custom scheduler class as django_celery_beat.schedulers:DatabaseScheduler in the settings file. But its still using the default PersistentScheduler. settings.py # Other settings # Celery CELERY_BROKER_URL = 'redis://localhost:6379/0' CELERY_CELERYBEAT_SCHEDULER = "django_celery_beat.schedulers:DatabaseScheduler" CELERY_RESULT_BACKEND = 'django-db' celery.py from __future__ import absolute_import, unicode_literals import os from celery import Celery from celery.schedules import crontab # set the default Django settings module for the 'celery' program. os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'myproject.settings') app = Celery('myproject') app.config_from_object('django.conf:settings', namespace='CELERY') # Load task modules from all registered Django app configs. app.autodiscover_tasks() # my tasks imported here However when i set custom scheduler in command line like this celery -A proj beat -l info --scheduler django_celery_beat.schedulers:DatabaseScheduler then everything works as expected. In nutshell, i want to set celery's custom scheduler in the django settings.py so that i don't need to specify that everything in the command line. UPDATE: If i change broker_url in the settings, the changes as reflected well. So there's nothing wrong with configuring settings.
