Hey guys ! I'm trying to implement a any to many relationship with Intermediary Models. I've been following https://docs.djangoproject.com/en/1.2/ref/contrib/admin/#working-with-many-to-many-intermediary-models And I have almost the same code except for names. The problem : that's crazy slow.
My table Group has 100 rows My table Person has like 100 0000 rows So, If I go to a Person, there is no problem to see his groups. But if from a group I want to see all the persons that's not possible. (page load never end) I had a look at the queries the admin generates. And I was a bit surprised. First it's selecting my group (eg:select * from group where is =1) Second it's selecting all my Persons and join it to membership giving my group id (eg:select person.* from person JOIN membership ON membership.person = person.id WHERE group = id) Third it's select all my memberships for my group (eg:SELECT * from membership WHERE group = id) Until here I guess it's fine. Finally it is selecting all my persons (eg : select * from person) :s And it is not doing only one time..... like 100 times So I'm a bit lost, is it the normal behavior ? if yes, is there a better way to do what i want to do ?
