PostgreSQL Django Query

Hi All,

I am using Python Django and PostgreSQL to build our report app.

I am using below mention query to find some details. the query mention
below is running fine in PostgreSQL command line and giving results in 2 sc
for 2 million cards but when I am trying the same in Django application it
is taking too much time and the web page is expired while running this
query.

can anyone help how to make the query faster in Django

rows = M_Assign.objects.raw(''' select C.id
<http://s.bl-1.com/h/dcktcHRZ?url=http://c.id/>,M."merchant_name",C."MERCHANT_ID",S."store_id"
Owning_Store_ID ,S."store_name" Owning_Store_Name,F."franchisee_name"
Owning_Group,C."ACCOUNT_NUMBER",C."STORE_ID",C."GIFT_LIST_REF" FROM
vdaccount_card_assign C INNER JOIN vd_merchant_master M ON
C."MERCHANT_ID"=M."merchant_id" AND C."MERCHANT_ID"='003561002966107' INNER
JOIN vd_store_master S ON S."store_id"=C."GIFT_LIST_REF" OR
C."GIFT_LIST_REF"='' INNER JOIN vd_franchisee F ON
S."franchisee_id"=F."franchisee_id" ''')
