Django - How to Use same view function for multiple different URL Endpoints, but different "parameter" sent?
I'm fairly new to Django and here's my case. If i have 3 endpoints that i can't modify, and i need to point them to one same View function such as : urls.py urlpatterns = [ ... url(r'^a/', views.functionz.as_view(), name='a'), url(r'^b/', views.functionz.as_view(), name='b'), url(r'^c/', views.functionz.as_view(), name='c'), ... ] If I'm restricted from changing the endpoints a/, b/, and c/ to something else that accepts parameters like xyz/a or xyz/b, how can my view function functionz identify the difference between them when it is being called? Can I do something like this pseudocode? views.py Class XYZ(API View): def post(self, request, format=None): if request.endpoint == '/a/': # do things if and only if the client hits /a/ -

How to catch an element from a for loop in Django template?
I'm looping through to different categories and rendering results (of its name and its associated pages). This code is rendering correctly. {% for category in categories %} <div class="row"> <div class="col-lg-4"> <h3><a href="{{category.get_absolute_url}}"></a>{{category.category_name}}</h3> {% for page in category.page_set.all %} <p><a href="{{page.get_absolute_url}}">{{page.page_title}}</p> {% endfor %} </div> </div> {% endfor %} I'd like to catch an specific element inside the for loop (to be precise the 4th one in the forloop counter) and customize it (adding some html and text only to that one). I tried using the forloop.counter like this: {% if forloop.counter == 4 %} <!-- modified content --> {% endif %} But there isn't any results (not showing any changes). Is there any way to do this? -

Django modelformset_factory: how to create field with constant value
Say I have a bakery which bakes 10 pies in a batch (i.e. all 10 pies go into the same oven). The objective is simply to record the weight (in grams) and cost of each pie (in $). Cost = weight * 0.01. So each pie is modelled as a PieRecord object, which has weight and cost: models.py from django.db import models class PieRecord(models.Model): """this will be in a modelformset """ # pie_name is a dummy field just to play with text input pie_name = models.CharField(max_length=20) pie_weight_grams = models.FloatField() # calculated: cost($) = pie_weight_grams * 0.01 cost = models.FloatField(default=0.0) I use modelformset_factory to generate 10 PieRecord forms at a shot, and surface on the web page (see views.py below). My question is: I would like to attach some fields that are specific to each batch of 10 pies (not each pie), e.g.: cook time (minutes, FloatField) cook name (CharField) cook date (DateField) cook temperature (degC, FloatField) If I simply add these fields to my PieRecord class, this would result in the user having to enter the same values 10 times (e.g. cook_name James baked this batch of 10 pies), which results in a lot more data entry than is needed; … -
How to implement tooltip with django form

This help text could be the help_text from the model, or I am happy to put it somewhere else (although it should go in either the model or the form, not in the template). Any help appreciated. -

Django - Display the number of users currently watching a live stream
I'm developing a Django site for a sports streaming service. It is necessary to display the number of users who are currently watching the broadcast. You can watch the broadcast only after authorization. What is the best way to implement this? At the moment I think that the best solution would be to send a js request to the Django server, but I think there is a better way. -

how to upload image correctly. Django
I am building a Django application (run in local) and I am having headaches about uploading files/pictures. I have read tons of questions/answers everywhere as well as followed the official doc, but somehow I still have problems. In my models.py: FuncionarioPathFoto = models.FileField( "Foto", upload_to = "images/", db_column= "FuncionarioPathFoto", null= False, blank = False ) In my views (I'm using inline forms, so the code is big): def create_funcionario(request): if request.method == "GET": form = FuncionariosForm form_funcionarioadicional_factory = inlineformset_factory(Funcionarios, FuncionarioAdicional, form=FuncionarioAdicionalForm, extra=1) form_funcionarioaux_factory = inlineformset_factory(Funcionarios, FuncionarioAux, form=FuncionarioAuxForm, extra=1) form_funcionarioarquivo_factory = inlineformset_factory(Funcionarios, FuncionarioArquivo, form=FuncionarioArquivoForm, extra=1) form_funcionarioadicional = form_funcionarioadicional_factory() form_funcionarioaux = form_funcionarioaux_factory() form_funcionarioarquivo = form_funcionarioarquivo_factory() context = { 'form': form, 'form_funcionarioadicional': form_funcionarioadicional, 'form_funcionarioaux': form_funcionarioaux, 'form_funcionarioarquivo': form_funcionarioarquivo, } return render(request, '../templates/funcionarios/form_funcionarios.html', context) elif request.method == "POST": form = FuncionariosForm(request.POST) form_funcionarioadicional_factory = inlineformset_factory(Funcionarios, FuncionarioAdicional, form=FuncionarioAdicionalForm) form_funcionarioaux_factory = inlineformset_factory(Funcionarios, FuncionarioAux, form=FuncionarioAuxForm) form_funcionarioarquivo_factory = inlineformset_factory(Funcionarios, FuncionarioArquivo, form=FuncionarioArquivoForm) form_funcionarioadicional = form_funcionarioadicional_factory(request.POST) form_funcionarioaux = form_funcionarioaux_factory(request.POST) form_funcionarioarquivo = form_funcionarioarquivo_factory(request.POST) if form.is_valid() and form_funcionarioadicional.is_valid() and form_funcionarioaux.is_valid() and form_funcionarioarquivo.is_valid(): funcionario = form.save() form_funcionarioadicional.instance = funcionario form_funcionarioaux.instance = funcionario form_funcionarioarquivo.instance = funcionario form_funcionarioadicional.save() form_funcionarioaux.save() form_funcionarioarquivo.save() messages.success(request, "Funcionário adicionado com sucesso!") return redirect(reverse('lista_funcionarios')) else: context = { 'form': form, 'form_funcionarioadicional': form_funcionarioadicional, 'form_funcionarioaux': form_funcionarioaux, 'form_funcionarioarquivo': form_funcionarioarquivo, } return render(request, '../templates/funcionarios/form_funcionarios.html', context) I put this … -
How to hide a field from a serializer in Django rest framework

Django profiles for multiple user types
I am new to Django. My application has three user types who are mutually exclusive.They can be identified using a choice field. Want to understand how to create different user profiles for different user types as each profile will have different properties. Let's say the user types are customer, employee and partner.After googling so many days, Only way I found was to inherit User/Abstract User model and have three different apps for each user type. That's there are will be login page, register page like wise for each user type. I thought I could at least have one app to handle user login and based on the user type from the choice field, to attached the correct user profile. Is this something that can be done. Second I want to provide the correct profile to the user when registering. Is this possible. Thank you in advance. I stated before I tried to have three apps. -
Sending data from Python to HTML in Django
I have a Django project with a form in an HTML file, and I'd like to update the text on the submit button of that form WITHOUT a page reload. Essentially: I click submit on the form Python handles the submit with the form data The button text is updated to say "show result" If I understand correctly, I have to use AJAX for this. The problem is that the form submit relies on an API call in Python, so the HTML essentially has to always be "listening" for new data broadcasted by the views.py file. Here's the code I have (which doesn't work): views.py: def home(request): if request.method == "POST": print("Got form type", request.content_type) return JsonResponse({"text": "show result"}) return render(request, 'home.html') home.html: (form code) <button id="submit" type="submit">Submit</button> (end form) <script type="text/javascript"> function queryData() { $.ajax({ url: "/", type: "POST", data: { name: "text", 'csrfmiddlewaretoken': '{{ csrf_token }}', }, success: function(data) { var text = data['text']; var button = document.getElementById('submit'); button.innerHTML = text; setTimeout(function(){queryData();}, 1000); } }); } $document.ready(function() { queryData(); }); </script> I've imported jQuery with the script <script src="https://ajax.aspnetcdn.com/ajax/jquery/jquery-1.9.0.min.js"></script>. Any idea why this doesn't work in its current state? Thanks! -
Debug the React part of a hybrid React+Webpack+Django in VS Code
I have a hybrid Django + React application: the React frontend is built using Webpack, added to the static files and included in a Django template page (this is based on this tutorial Modern Javascript for Django Developers). Is there a way of easily debugging the React/JavaScript part of the app in VS Code? This question seems close but the breakpoints stay unbound for me despite including the line from its answer. My entry point for React is in ./assets/app.js and the bundled file goes to ./static/js/js-bundle.js. Django serves the website on localhost:8000. webpack.config.js const path = require('path'); const HtmlWebpackPlugin = require('html-webpack-plugin') const MiniCssExtractPlugin = require("mini-css-extract-plugin"); module.exports = { mode: 'development', devtool: 'inline-source-map', entry: './assets/app.js', // path to our input file output: { filename: 'js/js-bundle.js', // output bundle file name path: path.resolve(__dirname, 'static'), // path to our Django static directory }, plugins: [ new HtmlWebpackPlugin({ inject: true, filename: path.resolve(__dirname, 'templates', 'app.html'), template: path.resolve(__dirname, 'templates', 'app-template.html'), }), new MiniCssExtractPlugin({ filename: "./css/[name].css", // change this RELATIVE to your output.path! }), ], module: { rules: [ { test: /\.(js|jsx)$/, exclude: /node_modules/, loader: "babel-loader", options: { presets: ["@babel/preset-env", "@babel/preset-react"] } }, { test: /\.css$/, use: ['style-loader', 'css-loader', 'postcss-loader'] }, ] } }; package.json [...] … -
