Given that \\(f(x)\\) is an odd function defined on \\((-1,1)\\).

\\((1)\\) If \\(f(x)\\) is monotonically decreasing on \\((-1,1)\\), and \\(f(1-a)+f(1-2a) < 0\\), find the range of the real number \\(a\\);

\\((2)\\) When \\(0 < x < 1\\), \\(f(x)={{x}^{2}}+x+1\\), find the expression of \\(f(x)\\) on \\((-1,1)\\).
