Ensure the most specific subcategory is selected in a chained dependent dropdown selection
I am implementing chained dependent combobox selection, so you start with one combobox for main category and once you select main category, another <select> appears for selecting a subcategory, and so on until the innermost (most specific) subcategory is selected. This currently works like as follows: whenever a value is changed in a combobox, an AJAX request is fired which calls a view that renders another <select> if a category has children, otherwise returns an HttpResponse which stops attaching the listener. I am using django-mptt to model my categories. So, I have a view for adding products and I want to ensure that the most specific subcategory (it has to be a leaf node) is selected and assign that category to my Product instance. Here is the view: @login_required def product_create_view(request): if request.method == 'POST': create_product_form = CreateProductForm(request.POST) else: create_product_form = CreateProductForm() return render(request, 'products/product_create.html', {'form': create_product_form}) Here is the form: from django.forms import ModelForm from .models import Product, Category class CreateProductForm(ModelForm): class Meta: model = Product fields = ( 'title', 'description', 'price', 'year', 'category', ) def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.fields['category'].queryset = Category.objects.filter(parent=None) Here is products/product_create.html: {% extends 'pages/base.html' %} {% block content %} <h1>Create a product</h1> <form … -
Django - Update/refresh table data in html with jQuery and ajax every x seconds
I am having a problem with automatically updating the table data and updating the date every x seconds using the jQuery and ajax code below. I am trying to look at another view (get_more_tables) and then append this data to the table without the need for a manual refresh, but i cant get it to update. If i check the console log the data is there and updating every 10 secs. I am new to programming, django, python etc, so i apologize for any poor programming techniques! I have attempted to add a few parts to the end of the ajax call such as the $alms_list = data; but i cant find the correct syntax to use. I have done some research and i think i need to loop through the rows, and use the .append? But i cant get this to work. Any help would be greatly appreciated. views.py '''python def home(request): #alms_list = data.objects.filter(date__gt=myDate).order_by('-date') myDate = timezone.localtime(timezone.now()) # Get Current Time formatedDate = myDate.strftime("%d-%m-%Y %H:%M:%S") alms_list = data.objects.filter(alm_date__gt=myDate).order_by('alm_date') return render(request, 'home.html', {'alms_list' : alms_list, 'date': formatedDate }) def get_more_tables(request): myDate = timezone.localtime(timezone.now()) # Get Current Time formatedDate = myDate.strftime("%d-%m-%Y %H:%M:%S") alms_list = data.objects.filter(alm_date__gt=myDate).order_by('alm_date') return render(request, 'get_more_tables.html', {'alms_list' : … -
How to make the a database field accept just one value for an user
I'm trying to associate a user with a paypal account, and just one. Which means that if there is a value on that field, the post request should return "There is already a value there" or simply don't work (Return status code 400). I've tried using the UniqueTogetherValidator in the serializer and use and ID as well. The problem with this approach is that it requires an 'id' field in the post request which is not generated yet (The id is auto-generated by the framework). Here is what I'm trying with my serializer implementation class PaypalAffiliateSerializer(serializers.ModelSerializer): # id = serializers.ReadOnlyField(required=False) class Meta: model = PaypalAffiliate validators = [ UniqueTogetherValidator( queryset=PaypalAffiliate.objects.all(), fields=['paypal', 'id'] ) ] fields = ('paypal', 'id') and here is my model class PaypalAffiliate(models.Model): paypal = models.EmailField() affiliate = models.ForeignKey(User, on_delete=models.CASCADE) def __str__(self): return self.paypal class Meta: unique_together = ('paypal', 'affiliate') How can I make the PayPal email field accept just one value for every user? -

Django: is there a difference in performance between .filter("key__in"=set) and .filter("key__in"=list)
I'm asking this question in the context where I already have a list and I'm wondering if it's worth converting it into a set to use in the filter query or not, i.e. which is better: some_set = set(some_list) some_qs = SomeModel.objects.filter("some_key__in"=some_set) vs some_qs = SomeModel.objects.filter("some_key__in"=some_list) I know that if you want to lookup the elements from a list a in another list b, it's generally worth converting list b into a set since x in list is O(n) and x in set is O(1). But I don't know how Django implements the query filter __in so I'm not sure which is the better option in this context. -
How to setup a Django server state before starting gunicorn
I'm building a Django server which I'm going to host using gunicorn and want to setup its (Django's) inner state (fetch and cache some data from the blockchain, start couple threads that would perform some background updates etc.) before starting an actual HTTP server with my API endpoints. While it's fairly easy to do with the "manage.py runserver" (create my own implementation with all the actions I need before actual server starting), I'm struggling to wrap my head around the best way to do that with the WSGI gunicorn server which seems to start right away with no obvious way to specify any pre-run actions. -
SSL: TLSV1_ALERT_PROTOCOL_VERSION while POSTING
I'm doing a project, which both dev and prod branches are hosted on a server and everything works fine. I had to install it on another server to separate dev from prod, which worked well until i try to use an API used to send mails with an internal product.

solr server stops indexing after some records
I have solr installed on AWS cloud, which is not able to complete my indexing. I have similar DB and solr on my local system where indexing runs fine and I can search all data. I have monitored memory consumption , heap size on AWS while indexing is running. Nothing seems unusual. python manage.py rebuild_index --noinput -b 1000 --workers 4 This command shows that 168252 records will be indexed while indexing stops at 164252 and it never completes. On local it completes all records indexing. What is the reason for this unusual behaviour ? -
Inline action with no object instance in Django Admin
I am having troubles with working with GenericTabularInline in my django app. The case is: I have some object called Status which has relation to some Property (ForeignKey). I would like to have an additional actions on that Status object in Property change form. I am using inline_actions library to create custom actions for Status object. The struggle is when I try to render that Inline instance if there is no Status object attached to my Property. Is there any way I can override my custom actions to render even if there is no Status object attached to my Property? Here is my Inline code: class AbstractPropertyCheckInline(InlineActionsMixin, GenericTabularInline): model = Status readonly_fields = ('status_type', 'last_check', 'additional_message') extra = 0 inline_actions = ['revalidate'] def revalidate(self, request, obj, parent_obj=None): # My revalidation code What revalidate does is that it creates a Status object and attaches it to the Property if such doesn't exist. I would like to trigger such behavior from within admin page -

Django bootstrap-pagination work with inherited templates?
Does "bootstrap-pagination" in django work with inherited template files? I have a situation like the following. I have a template file like so: *{% extends "shared/table.html" %}* *... some html stuff ... ....end of file ...* Then I have the table.html like so: *{% extends "shared/tablepage.html" %} {% load bootstrap_pagination %} <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" type="text/css" media="screen" title="no title" charset="utf-8"> <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/font-awesome.css" type="text/css" media="screen" title="no title" charset="utf-8"> <script src="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.js"></script>* *...some html table here...* *{% bootstrap_paginate pagination_query range=10 show_prev_next="false" show_first_last="true" %}* end of file. I am doing something wrong here. But what is that? I can see the list of page links in the page. But all pages contain all the records. The views file is absolutely "traditional". It contains the necessary code and that code works with template files that are not inherited (or use inheritance). Thanks in advance.
