Let's say I have: Calculator #1: Expression: (True AND False) AND (True OR False)
This expression should be a child of some calculator. class Calculator(models.Model): name = ... class Expression(models.Model): parent = models.ForeignKey(Calculator) boolean = AND or OR sub_exp1 = models.ForeignKey(Expression) sub_exp2 = models.ForeignKey(Expression) When I query all the expressions for the Calculator #1, I should get all the subexpressions. 1 AND 2 5 2 AND 3 4 3 leaf node of True 4 lead node of False 5 OR 6 7 6 leaf node of True 7 leaf node of False >From this, I can quickly apply my parse tree. How would I display the base case/leaf nodes in my model? Also, is there a better way? Thanks, I would really appreciate any help -- You received this message because you are subscribed to the Google Groups "Django users" group.
