In the Cartesian coordinate system $xoy$, the general equation of curve $C_{1}$ is $x^{2}+y^{2}+2x-4=0$, and the parametric equation of curve $C_{2}$ is $\begin{cases} x=t^{2} \\ y=t \end{cases}$ (where $t$ is the parameter). In the polar coordinate system with the origin $O$ as the pole and the positive half-axis of $x$ as the polar axis:  
$(1)$ Find the polar equations of curves $C_{1}$ and $C_{2}$.  
$(2)$ Find the polar coordinates $(ρ,θ)$ of the intersection points of curves $C_{1}$ and $C_{2}$, where $ρ \geqslant 0$, $0 \leqslant θ < 2π$.
