Send values from URL to JavaScript
I don't know JavaScript yet, so I got a function online to create and delete new fields on my HTML page, but, I'd like to give it one more function, which I'm not able to do. Here's what I need: I'd like that at the same time I click on it to delete the input field, it would call a function view to also delete the data. To delete the data, I had to create a new link inside the HTML, which is not the best way. Is there a way to make it work? Here's the code. edit.html {% extends 'base.html' %} {% load static %} {% block content %} {% include 'partials/_header.html' %} <style> a:link, a:visited{ color: #006600; } .btn-green{ background-color:#008000 ;color: #FFF; } .btn-green:hover{ color:#fff; background-color: #009900; border-color: #008000; } .btn-ico{ background-color:#008000; padding: 2px 5px; margin-bottom: 10; } textarea { height: 100px; } </style> <link rel="stylesheet" href="https://use.fontawesome.com/releases/v5.7.0/css/all.css" integrity="sha384-lZN37f5QGtY3VHgisS14W3ExzMWZxybE1SJSEsQp9S+oqd12jhcu+A56Ebc1zFSJ" crossorigin="anonymous"> <!-- Begin page content --> <main role="main"> <div class="container mt-4"> <form enctype="multipart/form-data" action="" class="form-group" method="POST">{% csrf_token %} <div class="form-group"> {{ form.nome_projeto.label_tag }} {{form.nome_projeto}} </div> {{ form_colab.management_form }} <label>Colaboradores do Projeto:</label> {% for colab in form_colab %} {{ colab.non_field_errors }} {{ colab.errors }} {% for hidden in colab.hidden_fields %} … -
Django annotate using WHEN CASE
I have a question regarding annotation in Django, and inside the annotation I have CASE WHEN conditions, same as in the following example: queryset = queryset.annotate( title=Case(When(title_filter, then=Value("any text")), When(test_filter, then=F('name')), When(test1_filter, then=F('test__name')), output_field=CharField()), key=Case(When(title_filter, then=F('category__id')), When(test_filter, then=F('test_id')), When(test1_filter, then=F('test1__id')), output_field=CharField())) I want to annotate these fileds, title, key. But, we can see that for the each field is applyed the same condition, like Case(When(title_filter), When(category_filter)). There is a posiblity to apply the condintion just once and after that to apply the value for each field ? Like: if title_filter: title = Value("any text") key =then=F('category__id') elif test_filter: title = F('name') key = F('test_id') -

'+add' button doesn't work properly when django-ajax-select is used
In short: django-ajax-selects works fine with filtering existing items, but gives JS error by adding new item. Details. Using Django 3.1. At Admin site one needs to create object of model Choice with ForeignField to model Question. Django-ajax-selects (DAS) is used to populate the field (dynamic filtering). By typing letters DAS handles the queryset and outputs the list of relevant questions. One can choose a question from the list and save new Choice. All this works fine. If no proper questions by typing are found then one can click +add button and add new question in popup window with form. After clicking 'Save' according to DAS docs: new question must be saved into the database; popup window must be closed; the edited field must be populated with new question . Screenshot with popup window The problem is that Django stops at step2: new question is created, the popup window is getting blank and doesn't close with "Popup closing ..." in the head. There is an JS error in the window: Uncaught TypeError: window.windowname_to_id is not a function at window.dismissAddRelatedObjectPopup (:8000/static/ajax_select/js/ajax_select.js:194) at popup_response.js:13 The HTML-code of the blank page is <!DOCTYPE html> <html> <head><title>Popup closing…</title></head> <body> <script id="django-admin-popup-response-constants" src="/static/admin/js/popup_response.js" data-popup-response="{&quot;value&quot;: &quot;6&quot;, … -

Render fields conditionally with Django-Filters
I'm working on my Django SAAS app in which I want to allow the user to have some custom settings, like disable or enable certain filters. For that I'm using django-user-setttings combined with django-filters and simple forms with boolean fields: class PropertyFilterSetting(forms.Form): filter_by_loans = forms.BooleanField(required=False) filter_by_tenants = forms.BooleanField(required=False) The issue is that when trying to apply those settings, I keep running into serious spaghetti code: views.py class PropertyListView(LoginRequiredMixin, FilterView): template_name = 'app/property_list.html' context_object_name = 'properties' def get_filterset_class(self): print(get_user_setting('filter_by_tenants', request=self.request)) return PropertyFilterWithoutTenant if not get_user_setting('filter_by_tenants', request=self.request)['value'] else PropertyFilter filter.py class PropertyFilter(django_filter.FilterSet): ... class PropertyFilterWithoutTenant(PropertyFilter): ... and I'd have to do the same thing with the rest of the features. Is there any better way to implement this? -
How to integrate AngularJs with Django
I have little/no knowdlege in AngularJs, i want to create a very simple SPA with django as backend and AngularJs as frontend. User will be able to Register, Login & logout all taking place on the same page when a user logs in they will see a message"Welcome (user email)". This is very easy to do in a normal django web app as we don't even need to create the whole authentication system. But i want to learn how to do this with AngularJS as my employer wants me to do. I have read the basics of AngularJs and it looked well explained (it made sense) but how to integrate it with django. I tried searching on the internet but there is nothing out there, the tutorials that are there are more then 7 years old. -

Django: Change a DB record of a model extending an existing model by 1-1-relation
I am extending the default User model with a custom Profile model. They have a 1-to-1 relation (OneToOneField). The Profile stores custom settings of its user. class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) allow_export = models.BooleanField(default=False) language = models.CharField(max_length=8, default='en') theme = models.CharField(max_length=32, default='light') I created a JS function which calls a Python API. The Python API should change the theme field of the online user (the page can just be reached when the user is logged in.). So this is the API call. Please not that the function request is a simple post/get request. The only important thing I do here is to send a JSON object with {theme: theme}, for instance {theme: 'dark'}. The request works well. from django.contrib.auth.models import User function changeTheme(theme) { let url = 'api/change-theme'; let data = { theme: theme }; let onSuccess = function (data) { console.log(data); } let onServerError = function () { console.log(data); } let onError = function () { console.log(data); } request('POST', url, data, onSuccess, onServerError, onError); } Now the issue: There is the python function api_change_theme. This function should change the theme of the user`s profile. def api_change_theme(request): # Get post data post = json.loads(request.body) # Get theme name theme … -

Django & Django REST Framework - Adding @decorator_from_middleware(MyMiddleware) to API class based view
I'm wondering if there is a simple way to utilise the @decorator_from_middleware from Django decorators with a class based Dango REST Framework view on a per action basis: e.g., something like this: @decorator_from_middleware(DatasetViewsMiddleware) def retrieve(self, request, uuid=None, *args, **kwargs): ...
