We compute the $\beta$-decay $ft$-values within the frameworks of the energydensity functional (EDF) and the interacting boson model (IBM). Based on theconstrained mean-field calculation with the Gogny-D1M EDF, the IBM Hamiltonianfor an even-even nucleus and essential ingredients of the interactingboson-fermion-fermion model (IBFFM) for describing the neighboring odd-oddnucleus are determined in a microscopic way. Only the boson-fermion andresidual neutron-proton interaction strengths are determined empirically. TheGamow-Teller (GT) and Fermi (F) transition rates needed to compute the$\beta$-decay $ft$-values are obtained without any additional parameter orquenching of the $g_A$ factor. The observed $\ft$ values for the $\beta^+$decays of the even-even Ba into odd-odd Cs nuclei, and of the odd-odd Cs to theeven-even Xe nuclei, with mass $A\approx 130$ are reasonably well described.The predicted GT and F transition rates represent a sensitive test of thequality of the IBM and IBFFM wave functions.
