I have a dynamic page that loads product details, but the html is loaded before the data.
So when I try to use static elements like an image I get an error stating the object "product" does not exist.
To fix this I gave every dynamic element v-if="product != undefined"
which does work, but doesn't seem like a very good way of solving this.
I'm initiating my data through the store like this
In my page i do:
async mounted() {
await this.fetchProducts()
},
computed: {
product() {
return this.$store.state.products.producten.filter(product => product.id == this.$route.params.id)[0]
}
}
Then in my store:
export const state = () => ({
producten: []
})
export const mutations = {
setProducts(state, data) {
state.producten = data
}
}
export const actions = {
async fetchProducts({ commit }) {
await axios.get('/api/products')
.then(res => {
var data = res.data
commit('setProducts', data)
})
.catch(err => console.log(err));
}
}
I tried replacing mounted()
with:
beforeMount()
,
created()
,
fetch()
but none seemed to work.
I also tried:
fetch() {return this.$store.dispatch('fetchProducts')}
Loader(v-if="$fetchState.pending")
Error(v-if="$fetchState.pending")
.product(v-else)
// Product details...
CodePudding user response:
You could use the fetch hook to dispatch fetchProducts
:
<script>
export default {
fetch() {
return this.$store.dispatch('fetchProducts')
}
}
</script>
In your template, use the $fetchState.pending
flag to prevent rendering the data elements until ready:
<template>
<div>
<Loader v-if="$fetchState.pending" />
<Error v-else-if="$fetchState.error" />
<Product v-else v-for="product in products" v-bind="product" />
</div>
</template>
