Hide subset of queryset used as Foreign Key by default....show complete queryset in Django admin
In my Django models a Product belongs to a ProductCategory class FinancialProduct(models.Model): product_category = models.ForeignKey(ProductCategory, null=True) I want to be able to create a new ProductCategory 'behind-the-scenes', so that by default they don't show up in any queries. The exceptions to this are Django admin, and one very specific other query. To achieve this, I created a Manager for ProductCategory: class ProductCategoryManager(models.Manager): def get_queryset(self): return super().get_queryset().filter(status=ProductCategory.STATUS_PUBLIC) def get_complete_queryset(self): return super().get_queryset() Then in admin.py: @admin.register(FinancialProduct) class ProductAdmin(admin.ModelAdmin): model = Product def get_queryset(self, request): return Product.objects.get_complete_queryset() Generally this works great, but when I go into Product on Django admin and try to add a hidden ProductCategory, it can't find it: product category instance with id 3 does not exist. Should I carry on down the path of trying to override the querysets Django admin uses, or is there a smarter way? Ideally I want to avoid having to use a filter everywhere, as it's the kind of thing people forget. Note: I've spotted the docs actually do not recommend this approach -
Status 500 for POST requests in django on IIS
Dear StackOverflow community, your help would be greatly appreciated. I have zero experience with IIS. Unfortunately, a Windows Server 2012 with IIS 8.5 is all I can get for the current project. I followed this post by Matt Woodward to get my Django app running on IIS. I serve static files by means of an application that references the static folder. The app looks the way it is supposed to look and all GET requests are processed properly. However, the response to all POST requests (on localhost and remotely) is Status 500 Server Error. If I run my Django app with the runserver command, the POST requests are processed properly. POST is NOT blocked in IIS Request Filtering -> HTTP Verbs. POST requests are sent to URLs like http:/site_title/update_plan/, not to html. The StackOverflow posts found here and here were not helpful. I suspect the problem is in the IIS settings, but maybe some special Django settings are required and I am missing it. Any ideas on what can be done to fix the problem would be of great help. Thanks! -

Django template {%load templatetags%} insert chars?
I'm triyng to use the django template system to generate a plain text file, but it seems that inserting this: {%load label_template_tags%} generate some strange variation to the row.

Django REST Framework slow on Gunicorn
I deployed a new application made on Django REST Framework running with Gunicorn. The application is deployed on 4 different servers and they are listening on a port (8001) which is consumed by an HAProxy load balancer. Unfortunately I am suffering many performance problems: many requests takes seconds to be served, even 30 or 60 seconds. Sometimes even the basic entry endpoint (like https://my.api/api/v2 which basically returns the list of the available endpoints) requires 10/20 seconds to respond. I don't think the problem is the load balancer because I have latencies connecting directly to any backend servers with my client, so bypassing the load balancer. And I don't think the problem is the database because the call to https://my.api/api/v2 as guest (not logged with any user) shouldn't make any database query. This is a performance test made with hey (https://github.com/rakyll/hey) on the basic endpoint without authorization: me@staging2:~$ hey -n 10000 -c 100 https://my.api/api/v2/ Summary: Total: 38.9165 secs Slowest: 18.6772 secs Fastest: 0.0041 secs Average: 0.3099 secs Requests/sec: 256.9604 Total data: 20870000 bytes Size/request: 2087 bytes Response time histogram: 0.004 [1] | 1.871 [9723] |■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■ 3.739 [0] | 5.606 [175] |■ 7.473 [0] | 9.341 [35] | 11.208 [29] | 13.075 … -
How to fix UI of BS DataTable on row append/prepend using mustache templating
I am using mustache templating to prepend a row on my bs_datatable upon successful submit using ajax. But the problem is that the datatable's UI becomes ruined after append. I have tried redrawing the datatable using .draw() but the newly prepended row now won't appear. What am I doing wrong? Or is it necessary for me to use mustache for this? Here's my codes: html: <div class="row mt10"> <div class="col-12"> <table id="data_table" class="table nowrap table-striped table-bordered"> <thead> <tr role="row"> <th>Column 1</th> <th>Column 2</th> <th>Column 3</th> </tr> </thead> <tbody id="data_table_row_cont"> {% for item in data %} <tr role="row"> <td>{{item.column_1}}</td> <td>{{item.column_2}}</td> <td>{{item.column_3}}</td> </tr> {% endfor %} </tbody> </table> </div> </div> //mustache template <script type="text/template" id="mustache_row_content"> <tr role="row"> <td>{{item.column_1}}</td> <td>{{item.column_2}}</td> <td>{{item.column_3}}</td> </tr> </script> script: datatable = $('#data_table').DataTable({ responsive: true, info: false, paging: false, scrollCollapse: true, "ordering": true, searching: false, }); $("#form").submit(function(e){ e.preventDefault(); jQuery.ajax({ type: "POST", url: url, dataType: "json", data: data, cache: false, contentType: false, processData: false, success: function(response){ if(response.success){ //get mustache template (row template) var template = $("#mustache_row_content").html(); //assigning values to mustache template var html = Mustache.to_html(template, {'item': response.data}); //prepending the row template to datatable's tbody $('#data_table_row_cont').prepend(html); datatable.draw(); } } }); }); -

How to store python list in django?
I have a list of np arrays. Each time i make a post, the image is converted to an numpy array, and that array is compared to my list of arrays. How do i store my list of numpy arrays in Django? Currently i have stored the list as a string in the List class, and recoverting it everytime i need to use it. class List(models.Model): encodings = models.TextField(max_length=20000) def __str__(self): return self.encodings so unknown_face_encoding is the list of numpy arrays that i wish to store: unknown_face_encoding = face_recognition.face_encodings(unknown_image) unknown_face_encoding_lists = [] for encoding in unknown_face_encoding: unknown_face_encoding_lists.append(encoding.tolist()) unknown_face_encoding_strings = json.dumps(unknown_face_encoding_lists) known_face_encoding_stored = List(encodings = unknown_face_encoding_strings) and then when i need to retrieve it, i do this: known_faces_str = List.objects.first().encodings known_faces_lists = json.loads(known_faces_str) known_faces_array =[] for encoding in known_faces_lists: known_faces_array.append(np.array(encoding)) what's the right way to do this ? -

The staff memeber will only get enquiries that have been assigned to them. I dont know how to go about this. should i make assigned_to field a ForeignKey, if so i have a custom user that inputs email and password. or should i use something like request.user.id. should i somehow find my id, and set this as default. or is there a better method. Maybe i should asssign the user or email address as a dictionary in the view. any advice will be greatly appreciated. -

Create Date Range Slider in Django Form
