How to get item value in v-slot:cell() template of b-table - BootstrapVue

Question

I'm a very new at programming. I'm trying to figure it out how to bind the data to get the link :href work using store, vuex and bootstrap-vue table. I have spent 4 days for this, and now I'm dying. Please help.

books.js(store, vuex)

books: [
    {
      id: 1,
      name: "name 1",
      bookTitle: "book1",
      thumbnail: '../../assets/img/book01.jpeg',
      url: "https://www.google.com",
      regDate: '2019-10'
    },
    {
       id: 2,
      name: "name2",
      bookTitle: "book2",
      thumbnail: "book2",
      url: "http://www.yahoo.com",
      regDate: '2019-10'
    },

BookList.vue

<script>
export default {
  name: "BookList",
  components: {
  },
  computed: {
    fields() {
      return this.$store.state.fields
    },
    books() {
      return this.$store.state.books
    },
    bookUrl() {
      return this.$store.state.books.url
    }
  },
  data() {
    return {
      itemFields: this.$store.state.fields,
      items: this.$store.state.books,
      //url: this.$store.state.books.url
    }
  }

};
</script>

<template>
  <b-container>
    <b-table striped hover :items="items" :fields="itemFields" >
      <template v-slot:cell(thumbnail)="items">
          <img src="" alt="image">
      </template>
      <template v-slot:cell(url)="items">
          <b-link :href="bookUrl" >link</b-link>
      </template>
    </b-table>
  </b-container>
</template>

Answer 1

The cell slot contains two properties you're generally interested in:

• item (the current row, or, to be exact, the current item in items)
• value (the cell - or, to be exact, the value of the current column within the item).

Therefore, considering your data, in the case of v-slot:cell(url)="{ value, item }", value is equivalent to item.url

Any of these would work:

<template v-slot:cell(url)="{ value }">
  <b-link :href="value">link</b-link>
</template>

<template v-slot:cell(url)="slot">
  <b-link :href="slot.value">{{ slot.item.bookTitle }}</b-link>
</template>

<template v-slot:cell(url)="{ item }">
  <b-link :href="item.url">{{ item.bookTitle }}</b-link>
</template>

Note your question contains a few minor issues which might prevent your code from working (itemFields is referenced but not defined, not using proper getters, etc...). For details have a look at the working example.
And read the docs!
