How to add names to a collection of constraints in JuMP using @constraints

I want to name different kinds of constraints for enhancing readability and debugging, what’s the right syntax to do it with @constraints, I know this is easy for @constraint(, base_name = “Name”). Below is my code with errors.
‘’’
using JuMP, HiGHS
M = Model(HiGHS.Optimizer)
I = [1, 2, 3]
J = [1, 2, 3]
@variable(M, x[I, J] ≥ 0)
@constraints(M, begin
[i in I], sum(x[i, :]) <= 5, base_name = “name1”
[j in J], sum(x[:, j]) >= 6, base_name = “name2”
end)
‘’’

I use something like this:

@constraint( M, name1[i in I], sum(x[i, :]) <= 5)
@constraint( M, name2[j in J], sum(x[:, j]) >= 6)

(Note: I did not test it for your case)

Keyword arguments in the plural macros need additional () around them:

using JuMP, HiGHS
M = Model(HiGHS.Optimizer)
I = [1, 2, 3]
J = [1, 2, 3]
@variable(M, x[I, J] ≥ 0)
@constraints(M, begin
    [i in I], sum(x[i, :]) <= 5, (base_name = “name1”)
    [j in J], sum(x[:, j]) >= 6, (base_name = “name2”)
end)

I’ll update the documentation.
