我正在尝试进行更新，我设法在 firebase 中完成更新，但在商店中没有更新。这是我的代码

editCar() {
      let result = this.balmUI.validate(this.formData);
      let { valid, message } = result;
      this.message = message;
      console.log(`Vrei sa editezi masina: ${this.formData.vehicle}`);
      console.log(utils.url);

      if (valid) {
        let data = {
          vehicle: this.formData.vehicle,
          color: this.formData.color,
          fuel: this.formData.fuel,
          status: this.formData.status,
          price: this.formData.price,
        };

        let requestParameters = { ...utils.globalRequestParameters };
        let token = window.localStorage.getItem("token");
        requestParameters.headers.Authorization = "Bearer " + token;
        requestParameters.method = "PUT";
        requestParameters.body = JSON.stringify(data);

        fetch(utils.url + "cars/" + this.formData.id, requestParameters)
          .then((res) => res.json())
          .then((res) => {
            console.log(res.message);
            if (
              res.message === "Decoding error!" ||
              res.message === "Your token expired!"
            ) {
              console.log("nu ai voie!");
            } else {
              data.id = res.id;
              this.$store.dispatch("editCar", data);
              this.$router.push("/");
            }
          });
      }

这是来自商店的索引，其中包含我的突变和操作。其他一切都正常工作

import { createStore } from 'vuex'

export default createStore({
  state: {
    cars: [],
    isAuthentif: false
  },
  getters: {
    cars: state => {
      return state.cars
    }
  },
  mutations: {
    SET_AUTH: (state, status) => {
      state.isAuthentif = status
    },
    SET_CARS: (state, cars) => {
      state.cars = cars
    },
    ADD_CAR: (state, car) => {
      state.cars.push(car)
    },
    DELETE_CAR: (state, id) => {
      var index = state.cars.findIndex(car => car.id == id)
      state.cars.splice(index, 1);
    },
    EDIT_CAR: (state, car) => {
      state.cars.forEach(c => {
        if(c.id === car.id) {
          c = car;
        }
      })
    }
  },
  actions: {
    login: ({ commit }, payload) => {
      commit('SET_AUTH', payload)
    },
    fetchCars: ({ commit }, payload) => {
      commit('SET_CARS', payload)
    },
    addCar: ({ commit }, payload) => {
      commit('ADD_CAR', payload)
    },
    deleteCar: ({ commit }, payload) => {
      commit('DELETE_CAR', payload)
    },
    editCar: ({ commit }, payload) => {
      commit('EDIT_CAR', payload)
    }
  },
  modules: {
  }
})

我认为 EDIT_CAR 是问题所在。 出了什么问题？为什么它没有在屏幕上更新。 我也尝试过使用这个 https://vuex.vuejs.org/guide/mutations.html#object-style-commit 像这样 c = {...c, car 但不起作用
