Hi:
   I am a beginner using django, I want to build a flexible data model like 
this:
   
Item_ID         Attribute    Value
1                      Attr1         V1
1                      Attr2         V2
2                      Attr1         V3
2                      Attr2         V4
1                      Attr3         V5

Uses can add new attribute (attr 4, 5..) without changing the database (do 
not add new columns)
How can I realize it in model, view and form with the function of creating 
Item and searching items on selected attrs?
The main problem confused me is that I cannot link form with model since 
the attribute is actually values not truly attributes.


Thanks!
