Hello, I am trying to implement a full text search in django 1.11, in my model product_name and foreign_name can have values in English and Spanish https://pastebin.com/RQS1AHtN, in pastebin I have published my model with a manually created index which works very well with the query, I would like to transpose that query to a queryset using both languages english and spanish, can anybody help me?

I used the following manual https://czep.net/17/full-text-search.html but I can not see light

I think this may be a solution: search_spanish = SearchVector('product_name', 'foreign_name', language='spanish') search_english = SearchVector('product_name', 'foreign_name', language='english') search = search_spanish + search_english

I think the queryset is not using the language, https://pastebin.com/KKMWyy1P :(

my error the SearchVector class receives the config parameter and not language, but when adding both classes it generates the following error: TypeError: SearchVector can only be combined with other SearchVectors

Only load details on demand don't load everything before your user ask, lazy load everything

And if the details are statics consider using PWA

If your view is a list type, maybe you should try paginating it

Hey guys, do anyone know how to get the size of file uploaded to s3 bucket from django

7000 records isn't very big. You could get away with loading all of it. Keep a JSON file in your assets, and your JavaScript or jQuery will access that. As long as it's cached by the clients browser it'll be fast on subsequent use of the page.

means all data will be loaded on page load? then of course the page will take longer time to load. maybe implement infinite scroll on your frontend

Hello everyone , I am building and application using DRF, I am using view sets to make the data avalible to the frontend, which is working fine. when i tried to make a delete request to the same view I got 403 error on the other hand if i make the delte request via the browsable API it gets executed !

does the browsable API has different rules or something ?

this is my viewset

Forbidden: /api/batchVS/test test two/ [06/Jul/2019 13:07:44] "DELETE /api/batchVS/test%20test%20two/ HTTP/1.1" 403 58

and this is what i get when i send the request from front-end

Its csrf error .

Think so
