The origin of repeating fast radio bursts (RFRBs) is still a mystery. Wepropose that short-lived RFRBs might be triggered from the tidal disruption ofwhite dwarfs (WDs) by intermediate-mass black holes (BHs). In this model, weshow that the remnant WD clusters after tidal collapse cuts the magnetic lineson the BH accretion discs, and during each fall of the clump, so that electronsare torn from the surface of the mass and instantly accelerated to therelativistic energy. The subsequent movement of these electrons along magneticfield lines will result in coherent curvature radiation. This short-lived radiotransients might accompany with the accretion process. The luminosity and thetimescale can be estimated to be $L_\mathrm{tot}\sim 1.96\times10^{40}~{\rmerg~s^{-1}}$ and $\Delta t\sim1.14~{\rm ms}$, respectively, which areconsistent with the typical properties of RFRBs. Moreover, the total event rateof our model for generating RFRBs might be as high as $\sim 10~\rm{yr^{-1}~Gpc^{-3}}$.
