Vue.js and django rest framework for implements a cascading dropdown list
I would need help building a request to my backend API. I currently have a form with a drop down list. The data in this list comes from this.$Http.get('/ quality/api/affaires/') Below this drop-down list, I have another list. This list, I would like it to be empty until the 1st is not selected, then it is implemented with data according to the selection above. Backend side (Django) I have 2 models which are "Affaires" and "AffairesOfs". I used Serialize and I can therefore request each of these models via api/affaires and api/affairesofs In the "AffairesOfs" model I have a foreignekey (idaffaire) on the id of the "Affaires" model. Finally, I would like my second list to be made up of all the “affairesofs” linked to the “Affaires” selected. For now, I have my 2 drop-down lists but I can't find a way to link the second to the first. I tried different methods found on the internet (with the use of v-model, ...) but could not achieve a result. I can't even get the value selected from the first list to display it in the console, or in a . i think I need a change event on the first … -

Form for updating model info is blank
I am trying to provide a form to update user info such as employment, location, birthday, interests. The form I tried to make will not show any of this info however, it just shows a submit button. user_info = models.UserInfo.objects.get(user=request.user) if request.method == 'POST': form = UserChangeForm(data=request.POST, instance=request.user) if form.is_valid(): form.save() return redirect('login:login_view') else: form = UserChangeForm(instance=request.user) context = { 'user_info' : user_info, 'form ' : form } return render(request, 'account.djhtml',context) I'm pretty sure I need to use user_info but Im not to sure how to do that.

How to import pickled python object into Django view.py file
This file runs perfectly well on its own: import pickle with open('model.obj', 'rb') as f: model = pickle.load(f) print(len(model)) But what I really want to do is to use model, which is a very large stored python dictionary, in my Django views.py file, like so: from django.shortcuts import render from modeler.load_model import model def page(request): return render(request, 'page.html', {'model':model}) However, when I try this, I get the error below: File "C:\Users\mmm\PycharmProjects\MyProject\modeler\load_model.py", line 3, in <module> with open('model.obj', 'rb') as f: FileNotFoundError: [Errno 2] No such file or directory: 'model.obj' I don't understand why, because if I run the first file directly it works fine - the only extra step here is importing it into views.py (I tried including the entire load_model.py code within views.py at first, but got this error, so then tried it in this separate file and it worked on its own, so obviously the issue is that I don't know how to correctly load/import my python model objects or files within Django. -
How to dynamically route to a URL with ID of an element fetched using JQuery on Django
I am populating data(Customer order in my case) from database into a table using Django template tags. I have assigned the unique ID( order.id) to the id of "a" tag. On click of this "a" tag, I have written a function which fetches the id of the clicked button and then opens a modal dialog. Now I need the modal body to show the order.name dynamically and then give the user two options - 1. 'No', which closes the modal 2. 'Yes', which should route to views along with the id fetched. I am stuck here. html <div class = 'col-md-7'> <h4>ORDERS</h4> <hr> <div class = 'card card-body'> <a class = 'btn btn-primary text-white' href = "{% url 'createOrder' %}">Create Order</a> <table class = 'table table-sm'> <tr> <th>Product</th> <th>Date Ordered</th> <th>Status</th> <th>Update</th> <th>Remove</th> </tr> {% for order in orders %} <tr> <td>{{order.Product.name}}</td> <td>{{order.created_on}}</td> <td>{{order.status}}</td> <td><a href = "{% url 'updateOrder' order.id %}" style = "color: #005ce6;"><i class="fas fa-pen" style = "padding-left: 5mm;"></i></a></td> <td><a href = "#" class = 'delete' id = '{{order.id}}' style = "color: #b30000;"><i class="fas fa-times" style = "padding-left: 6mm;"></i></a></td> </tr> {% endfor %} </table> </div> </div> <script> $(".delete").click(function() { var id = this.id; $('#modelId').modal('show'); }); </script> <!-- … -

django sites and showing id in admin editor
I'm using the Site module in django. In the admin interface, I see domain name and display name. I'd really like to see the primary key id, as well, however, since I specify the sites by SITE_ID. Now I could do this by editing ./venv/lib/python3.7/site-packages/django/contrib/sites/admin.py, but that's poor form in so many ways. I'd just add "id", thus: class SiteAdmin(admin.ModelAdmin): list_display = ('id', 'domain', 'name') search_fields = ('id', 'domain', 'name') I did the following in one of my models.py files, which helps in the shell but doesn't show up in admin: def site_name(self): return '{domain} ({id})'.format( domain=self.domain, id=self.id) Site.__str__ = site_name Any suggestion how to do this (or pointer on what I'm doing wrong that I think I want it)? -
