python 3.x - Pyomo Using a non-set component as an indexed set

Question

I am new to Pyomo, but trying to formulate a model, which has one set of constraints, that I stuck to define. Lets assume, I have following simple code to show what I am trying to do

m = ConcreteModel()

m.rs = Set(initialize =[rs for rs in RS])
m.a = Set(initialize=[a for a in A])
m.t = ContinuousSet(bounds=(0, 10))

m.E = Var(m.rs, m.t)
m.tau = Var(m.a, m.t)

I know it is not correct to use a non-set component tau(t, a) as an indexed component, this is just to show simply I need:

 m.E[rs, t] == sum(m.E[rs, t + tau(t, a)] for all a in ...)

The value of tau(t, a) are calculated within the model when solving it. Any idea, how this sort of constraint con be written? Your help would be highly appreciated!
