Django createView passing current user_id to Modelform

Is there a way to return two combined lists from get_queryset instead of just the query set?
I am using Django to generate a generic.ListView of objects. I am also using Elastic Search for search results. My question is how can I combine my queryset with an ordered list of JSON objects? get_queryset only allows me to return one variable (the queryset) but I need get_context_data to be able to access both the queryset and the associated metadata for the search results. I created a below hack that works but looking for a better solution. def get_queryset(self): # just get 2 documents, in my actual code the queryset is generated by a list of IDs # from the Elastic Search query qs = Document.objects.all()[:2] # create some fake search results, in my actual code I get a similar looking JSON # objects with metadata like result score or highlighted snippets from the search corpus fake_results = [ { 'meta': { 'highlight': { 'title': ['ABC'], 'content': ['123', '456'], } } }, { 'meta': { 'highlight': { 'content': ['789'], } } } ] # this is a hack (i think) but need to merge the metadata from search results into the queryset object for doc, result in zip(qs, fake_results): if 'highlight' in result['meta']: doc.snippet = result['meta']['highlight'] return qs def … -

Caching the result of a query to the database
When rendering a page, a heavy query to the database is performed. My task is to cache the queryset obtained in the query and use it later. If 5 minutes have passed since the last initialization of the cache during the next cache query, the old cache should be removed and new data should be written from the database. Now I have written the logic without taking into account the timing, and further I have a problem with understanding how to connect the timer. class BlacklistCache: def __init__(self): self._cache = {} @property def cache(self): return self._cache @cache.setter def cache(self, value): self._cache = value @cache.deleter def cache(self): del self._cache blacklist_cache = BlacklistCache() def check_blacklist_cache(item_type): if blacklist_cache.cache: return blacklist_cache.cache else: blacklist = BlacklistedItem.objects.filter(item_type=item_type).values_list('item_id', flat=True) blacklist_cache.cache = blacklist return blacklist_cache.cache Could you get me any advice, or maybe most efficient approach? -
Data rollbacking when using AJAX function in Django?
I have an application that displays data to the users. There is a secondary column where users can enter a correction. I created an AJAX function that saves the data entered and updates my database. The application was working fine. I started to do some testing and today I found out that when I enter a value in the editable columns, after like 10 minutes it is deleted. I did queries in my database. When I query the row where I edited the value, it is shown correctly in my SQL database, and after 10 minutes, it is reverted. I don't understand why this is happening, and I was almost certain that it wasn't happening before. This is how my html/js script looks like: <head> <link rel="stylesheet" type="text/css" href="{% static 'css/dashboardStyle.css' %}"> </head> <body> <br> <br> <br> <br> <h1 class='fade-in'>Hello, {{ name }}</h1> <br> <br> <br> <br> <table class="content-table"> <thead> <tr> <th>ID</th> <th>MonthlyAccess</th> <th>MonthlyAccess_E</th> <th>QTY</th> <th>QTY_E</th> <th>GrossProfit</th> <th>GrossProfit_E</th> <th>Source</th> <th>Comment</th> </tr> <tbody> {% for datadisplay in Fact_POSTransactions %} <tr> <td>{{datadisplay.id}}</td> <td>{{datadisplay.MonthlyAccess}}</td> <td class="editable" data-id="{{ datadisplay.id }}" data-type="MonthlyAccess_E">{{ datadisplay.MonthlyAccess_E }}</td> <td>{{datadisplay.QTY}}</td> <td class="editable" data-id="{{ datadisplay.id }}" data-type="QTY_E">{{ datadisplay.QTY_E }}</td> <td>{{datadisplay.GrossProfit}}</td> <td class="editable" data-id="{{ datadisplay.id }}" data-type="GrossProfit_E">{{ datadisplay.GrossProfit_E }}</td> <td class="editable" data-id="{{ … -

Custom Upload Handlers in Django
I'm trying to create my own custom upload handlers on Django with the goal of being able to upload sub-directories. I ccouldn't find any resouce to build my own upload handlers so I saw Django Upload Handler on Github I basically copy and paste it in the begining to check all works fine and then make my changes, but I'm missing something, because it doesn't return the files to the request, so I'm currently lost, I think maybe that Django uploads handlers isn't what I think it is and needs some changes in order to work, but I neither know what changes, because the handler doesn't return any NotImplementedError. Any suggestion will be much appreciated.
