Trying to define Vuex mutations like this:
export default {
props: {
store: String
},
methods: {
...mapMutations({
changeModel: `${this.store}/changeModel`
})
}
}
Encountering an error message:
An error occurred: Uncaught TypeError: Cannot read property 'store' of undefined
How can I properly incorporate props into the module mutation name?
I aim to map
this.$store.commit('form1/changeModel')form1 is specified by props.
If you're looking to utilize the Vuex helper mapMutations with a function that operates using this, it is indeed possible.
While there isn't an official documentation available for this feature, you can refer to the example provided in the Vuex unit test helpers.spec.js which demonstrates how it can be done.
const vm = new Vue({
store,
methods: mapMutations({
plus (commit, amount) {
commit('inc', amount + 1)
}
})
})
Furthermore, this method allows for passing parameters to mutations, which is often required in certain scenarios.
To implement this in your own code:
export default {
props: {
store: String
},
methods: {
...mapMutations({
changeModel(commit) { commit(`${this.store}/changeModel`) }
})
}
}
When used within your component, you simply call changeModel(), as mapMutations handles injecting the commit parameter automatically.
It's worth noting that while this approach may add complexity compared to a straightforward this.$store.commit() method, it could be beneficial if your requirements are more intricate than those covered in the example snippet.
It seems that binding this on mapActions is not possible in this case. However, you can still utilize $store.dispatch to call it.
methods: {
updateModel() {
this.$store.dispatch(`${this.store}/updateModel`);
}
}
While it may not be the exact solution you were seeking, its impact remains consistent. Since mutation is a variable parameter, it makes sense to include it as an input parameter in a function instead of modifying the mutation name directly. One possible approach could involve creating an action in the store like so:
changeModel ({dispatch, commit, rootGetters}, mutationName) {
commit(`${mutationName}/changeModel`, {}, {root: true})
})
This action can then be utilized in the component by passing the mutationName as an argument.
