How to return Boolean from jQuery plugin to html?
I am currently working on a password strength meter that provides real-time update to the user via onkeyfocus event. I have decided to use https://github.com/elationbase/jquery.passwordRequirements for this purpose. Currently I am trying to return a Boolean from the jQuery plugin to my html so that I could check if the user input password has met the requirement completely. If it does not, to prevent them from further continuing in whatever they are doing. Below is what I have came up with so far. My question is how can I pass the var is_passed back to the html? jQuery Plugin (function($){ $.fn.extend({ passwordRequirements: function(options) { // options for plugin var defaults {...}; options = $.extend(defaults, options); var is_passed = false; // the variable that I wish to return return this.each(function() { ... //skipping all the checks $(this).on("keyup focus", function(){ var thisVal = $(this).val(); if (thisVal !== '') { checkCompleted(); if (is_passed === true) { console.log('is_passed', is_passed); return is_passed; } } )}; HTML <script> $(document).ready(function () { $('.pr-password').passwordRequirements({}); var is_passed = $('.pr-password').passwordRequirements({}); //not working as it returns an Obj }); </script> -

Linkify Foreign Keys with Django Tables2 and Slugs
I am trying to build summary tables with clickable links that drill down to lower levels. The hierarchy in descending order is Division -> Region -> Branch -> Profit Center where each profit center can have multiple "receivables." I want the division summary view to show all of the regions (e.g. California, Central Texas, Ohio, etc) and a sum of the 'total_amount' for the regions. I want to be to click a region and it drills down to the branches where I can see a summary for each branch. So on and so forth I've spent far longer than I would like to admit on this and the lines commented out on tables.py is just a fraction of what I have tried.

Code run in setUpTestData for django testing is not captured in test time
When I run tests using setUpTestData() the time spent in setUpTestData() is not captured.

Django Forms - Multi-Step Save Progress Along the Way
Just looking for a bit of a push in the right direction. I'm creating a multi-step user sign up to receive a personalized assessment. But I'm having trouble trying to wrap my head around the multi-step progress within Django and a SQL point of view. These are my steps, each to be a separate form: Sign Up (Make an Account) Complete Profile Information Create an application Complete required questions within application - This may need to be broken down even further. I've figured out redirections from each form, but my biggest concern is saving which step they're up to. E.g. What if they close the browser at end of step 2, how do I have a way to prompt them to come and complete step 3 onwards. To make it clear, I'm not looking for saving the state within the browser. Needs to be saved within the database to support access from other devices, for example. To add onto it, what if I was to allow them to make multiple applications (steps 3 and 4), but only allowing one to be open at a time. E.g. One gets rejected but we allow them to reapply. Just looking for some tips/suggestions … -
Expected behavior of "in" filter in Django-Filter with Graphene
Suppose I have models in Django like so model Foo: bar = ManyToMany(Bar) model Bar: baz = String and some object foo of type Foo, like so: foo.bar = [Bar(baz='fizz'), Bar(baz='buzz')] (so basically, some Foo object with more than 1 distinct related Bar) and then if I create a schema with the following filter field foo_bar__baz: ['in'] and I do a query with fooBarBazIn: ['fizz', 'buzz'], the same foo object is returned twice (whereas if I did only fooBarBazIn: ['fizz'], the object foo would only be returned once). This behavior extends to n related fields and m arguments in the filter; if an object matches k<m of these arguments, it will be returned k times in the resulting query (up to a maximum of n times) - whereas I would expect the same object to only be returned once. Is this behavior intentional? -

I'm working in a Python project using Django framework e I'm having some troubles such as: first we have a page to receive a integer value and we submit this value, after we'll have a new page that contains N integer field, where N is the input value from the first page. Below I show models.py: class Numero(models.Model): n=models.IntegerField() def back(self): return self.n class Peso(models.Model): peso=models.IntegerField() def __str__(self): return self.peso class Preco(models.Model): preco=models.IntegerField() def __str__(self): return self.preco views.py é: def index(request): template=loader.get_template('app/index.html') n=0 if request.method=='POST': n = Objetos(request.POST) context={'n': n} return render(request, 'app/index.html', context) def valores(request): template = loader.get_template('app/valores.html') peso=0 preco=0 peso_unitario=[] preco_unitario=[] **N=int(n_objetos)** for i in range(N): if request.method=='POST': peso=Peso_Unitario(request.POST) preco = Preco_Unitario(request.POST) if i == 0: peso_unitario = peso preco_unitario = preco else: peso_unitario.append(peso) preco_unitario.append(preco) context={'peso_unitario': peso_unitario, 'preco_unitario': preco_unitario} return render(request, 'app/valores.html', context) In N=int(n_objetos) **N=int(n_objetos)** is the drouble because I wanna return the value received before. index.html: <form action="/app/valores/" method="POST"> {% csrf_token %} <label for="n_objetos">n_objetos:</label> <input id="n_objetos" type="number" value=""/><br> <label for="peso_maximo">peso_maximo</label> <input id="peso_maximo" type="number" value=""/><br> <input type="submit"> </form> <a href="/app/valores/"></a> valores.html: <form action="% url 'app:Resultados' %" method="POST"> {% csrf_token %} <label for="peso_u">peso_u</label>; <input id="peso_u" type="number" value=""/><br>; <label for="preco_u">preco_u</label>; <input id="preco_u" type="number" value=""/><br>; <input type="submit">; </form> <a href="% … -

Mobile double tap issue
I was developing a website using django. Everything is responsive the way I wanted it to be, but when I change to mobile mode, the dropdown menus needed double tap to send me to the link I wanted. single tap is acting as a hover evenif I don't have hover effect. Here is my code. html code: <ul class="custom-menu"> <li><a href="{% url 'account' %}">{% "Account" %}</a></li> <li><a href="{% url 'orders' %}"></i> {% "Orders " %}</a></li> <li><a href="{% url 'logout' %}"> {% "Logout" %}</a></li> </ul> css code: .custom-menu { position: absolute; padding: 15px; background: #FFF; -webkit-box-shadow: 0px 6px 12px rgba(0, 0, 0, 0.175); box-shadow: 0px 6px 12px rgba(0, 0, 0, 0.175); z-index: 100; top: 100%; min-width: 200px; opacity: 0; visibility: hidden; -webkit-transition: 0.3s all; transition: 0.3s all; } .dropdown.open>.custom-menu { opacity: 1; visibility: visible; } It works on desktop but it needs double tap on mobile. I have tried using @media (pointer: fine) {}, but it makes the dropdown always visible. Thankyou in advance for your help! -

Is it possible to access an SQL database migrated using Django with a JavaScript ORM instead of raw SQL for a microservice architecture?
Suppose that I have an app where the models have been created using Django ORM and Django acts like an API for authentication and gives control to the relation model User using its ORM. At the same time, we want to use Express JS to continuously update a field in one the User model for some feature that requires performance. Is it possible to use a JavaScript ORM with Express JS to update such field? If yes, then how? -
Why does custom delete function didn't work?
I am working on DRF (Django) API I have a simple ModelViewSet. Delete request is working good for this: class BuildingObjectViewSet(viewsets.ModelViewSet): permission_classes = [AllowAny] serializer_class = BuildingObjectSerializer queryset = BuildingObject.objects.all() I want to customize delete function. But this delete code works too long time > 1 minute What is the reason of too long time of request? class BuildingObjectViewSet(viewsets.ModelViewSet): permission_classes = [AllowAny] serializer_class = BuildingObjectSerializer queryset = BuildingObject.objects.all() def destroy(self, request, *args, **kwargs): instance = self.get_object() deleted_id = instance.pk self.perform_destroy(instance) response = { "message": "BuildingObject has been deleted.", "building_object_id": deleted_id } return Response(response, status=status.HTTP_204_NO_CONTENT) models.py class BuildingObject(models.Model): name = models.CharField(max_length=32) address = models.CharField(max_length=200) urls.py path( "building_objects/<int:pk>/", BuildingObjectViewSet.as_view({ "delete": "destroy", "get": "retrieve", "patch": "partial_update", }), name="building_objects_detail" ),
