Let \\(f(x)= \dfrac {e^{x}-1}{x}-ax-b\\) where \\(a\\), \\(b \in \mathbb{R}\\) and \\(e\\) is the base of the natural logarithm.

\\((1)\\) If the tangent line of the curve \\(y=f(x)\\) at the point \\((1,f(1))\\) is \\(x+2y+4=0\\), find the values of \\(a\\) and \\(b\\).

\\((2)\\) When \\(b=1\\), if there always exists a negative real number \\(m\\) such that \\(f(x) < 0\\) holds true for all \\(x \in (m,0)\\), find the range of values for the real number \\(a\\).
