QUESTION
I would like to save an elasticsearch.Config struct to a JSON file. The code looks like this:
...ANSWER
Answered 2021-Jan-20 at 05:31elasticsearch.Config
contains exported RetryBackoff
field of said type func(int) time.Duration
. By default, json.Marshall
tries to marshal all exported fields and, for obvious reason, fails to do so.
AFAIK, the only way to customize struct fields marshaling is struct tags, and you can not add them to another package type. So the only way I see is to make your own struct with necessary fields from elasticsearch.Config
, fill and then marshal it.
QUESTION
I am trying to implement search suggestions using django-elasticsearch-dsl-drf
for streets.
This is documents.py

ANSWER
Answered 2020-Nov-22 at 22:08It looks like you're using wrong endpoint for suggestions. Correct name is suggest
.
Example: http://127.0.0.1:8000/search/publishers/suggest/?country_suggest__completion=Ar
As of your question about using two fields for suggestion at once, it's possible to get suggestions for multiple fields at once. For instance, if you have title
and author
, both properly indexed and configured, you could query it as follows:
http://127.0.0.1:8000/search/books/suggest/?title_suggest=wa&author_suggest=le
This will, however, return you the following result:

Answered 2020-Jul-03 at 08:20The Elasticsearch response which you've posted as JSON seems to not entirely correct (few brackets are missing and bad indentation) I've made an edit though, so no need to worry.
Coming to loop issue, this how your for-loop should like:
QUESTION
I've translated my Model fields with django-modeltranslation and implemented search using django-elasticsearch-dsl.
Problem: django-modeltranslation creates translation fields in DB, and not in my Models, and search is working only for fields created by Model. As django-elasticsearch-dsl is checking Models to rebuild search index.
When I try:
python3 manage.py search_index --rebuild
I get the error:

Answered 2020-Apr-09 at 15:51You can add the fields in the Document
class explicitly. Like following
QUESTION
Ok, so I have two bits of code. First off is a simple for loop that works great
...ANSWER
Answered 2020-Feb-02 at 19:49Instead of defer wg.Wait
, use wg.Wait
at the end of the for-loop. You are using the data constructed by the goroutines in the for-loop right after for-loop completes, and you're not waiting for all the goroutines to complete before you use that data.
When you use defer wg.Wait
, waiting happens at the end of the function. The for-loop using the data operates on incomplete data because the goroutines are still running.
When you use wg.Wait
at the end of the for-loop, you first wait for all the goroutines to end, and then use the data generated by them.

QUESTION
I am using django-el-pagination in Django project to show documents.
But I found that when I have more than 90k documents, the page loads very slowly.
I think that 'get_queryset' function runs again when sending ajax to load more.
This makes page load slowly.
Is there any way to slice the existing objects list instead of query all objects again.
...ANSWER
Answered 2018-Apr-18 at 09:31Found the problem, my old code query all objects every time,
return Entry.objects.filter().order_by('date')[::-1]
and the new code will run internal query command to query severl objects each time.
return Entry.objects.filter().order_by('date')
With elasticsearch, I use the answer here, it create a proxy between the Paginator and the Elasticsearch query.
