如何在Wagtail（django）中使用values_list？

Question

hi sorry for my poor English

Why wagtail search return PostgresSearchResult after search ?

i want PageQuerySet

like Django postgres search backend because I can not use values_list after search

i want to get list of page path ( because i want to find pages parents(Category Page) by path )

and i can't use values_list before search because it does not work

i know, i can use Forloop but this takes about 5 seconds for each run

My code is very simple :

Django Way : #Work

ProductPage.objects.filter(title__search="phone").values_list('path')

Wagtail Way : #NotWork :(

ProductPage.objects.search(query).values_list('path')

It is a bit counter intuitive but you need to always put the search(query) call last.

Reading the Search docs , you will see a note:

• The search() method will convert your QuerySet into an instance of one of Wagtail's SearchResults classes (depending on backend). This means that you must perform filtering before calling search() .

This means that to get a mostly equal set of results you will need to do the following:

query = 'phone'
ProductPage.objects.values_list('path').search(query)

Note the search is the last call. The search will still function as expected, I have also tested a similar situation on my setup.

values() , values_list() , filter() all return QuerySets where as the Wagtail search() takes a QuerySet and returns a non-QuerySet object. The actual database querying only happens when you iterate (or use) a QuerySet so the order of the QuerySet functions do not matter.
