如何在不更改类型的情况下从SearchQuerySet获取n个搜索对象？

Question

I am trying to get the to 10 objects like :

q_auth = SearchQuerySet().filter(content=validate_query)
q_auth = q_auth[:10]
print type(q_auth)

The output I want is: <class 'haystack.query.SearchQuerySet'> but I am getting is <type 'list'> .

Can some one please help me out?

Answer 1

I tried something similar like your code but got the output like this:

<class 'django.db.models.query.QuerySet'>

Based on what you've got, I think you can try something like:

print type(q_auth[0])

Answer 2

Looking at the source , you will see that q_auth[:10] returns a list of results. A SearchQuerySet is lazy and might not have all the results until you retrieve them with slicing, ie q_auth[:10] .

Just do:

first_results = q_auth[:10]   

and access a result with:

first_results[0]

I recommend not to do this:

q_auth = q_auth[:10]

because your instance q_auth of SearchQuerySet would not be available for retrieving more results later.
