Converting polynomials to pari

[Benjamin Matschke]

What is the right (and most stable) way to convert polynomials over number fields to a corresponding pari object?

I want to work with polynomials over number fields in sage using methods from pari (for example pari's rnfpolredabs).

The following code raises a PariError (incorrect priority in gtopoly: variable y <= t), and it persists if I rename the sage variables.

R.<x> = QQ[]

K = NumberField(x^2+2, "k")
pK = pari(K)
print("pK:",pK) #uses variable "y"

S.<t> = K[]
g = t^3 + 2
pg = pari(g)
print("pg:",pg)

I used Sage 9.0 and 8.8.

Thanks,

Benjamin
