Custom record field rendering

Customizing how AdminForth renders the cells with record values

Let's change how AdminForth renders the number of rooms in the 'list' and 'show' views. We will render '🟨' for each room and then we will print square_meter at the same cells.

Create directory custom. Create a file RoomsCell.vue in it:

./custom/RoomsCell.vue

<template>
  <div class="flex items-center">
    <span v-for="room in record.number_of_rooms">
      🟨
    </span>
      
    {{ record.square_meter }} m²
  </div>
</template>

<script setup lang="ts">
import type { AdminForthResourceColumnCommon, AdminForthResourceCommon, AdminUser } from '@/types/Common';

const props = defineProps<{
    column: AdminForthResourceColumnCommon;
    record: any;
    meta: any;
    resource: AdminForthResourceCommon;
    adminUser: AdminUser
}>();
</script>

Now you can use this component in the configuration of the resource:

./resources/apartments.ts

{
  ...
  resourceId: 'aparts',
  columns: [
    ...
    {
      ...
      name: 'number_of_rooms',
      components: {
        show: '@@/RoomsCell.vue',
        list: '@@/RoomsCell.vue',
      }
    },
    ...
  ],
  ...
}

Here is how it looks:

In very similar way you can render how cell is rendered in 'edit' and 'create' view. You can use it for creating custom editors for the fields. Check component specs to understand which props are passed to the component

Parametrizing the custom components

Sometimes you need to render same component with different parameters. You can use full component declaration

./resources/apartments.ts

{
  ...
  resourceId: 'aparts',
  columns: [
    ...
    {
      ...
      name: 'number_of_rooms',
      components: {
       show: '@@/RoomsCell.vue',
       show: {
         file: '@@/RoomsCell.vue',
         meta: {
           filler: '🟨',
         },
       },
       list: '@@/RoomsCell.vue',
       list: {
         file: '@@/RoomsCell.vue',
         meta: {
           filler: '🟦',
          },
        }
      }
    },
    ...
  ],
  ...
}

Now our component can read filler from meta prop:

./custom/RoomsCell.vue

<template>
  <div class="flex items-center">
    <span v-for="room in record.number_of_rooms">
     🟨
    {{ meta.filler }}
    </span>
    {{ room.square_meter }} m²
  </div>
</template>

<script setup lang="ts">
import type { AdminForthResourceColumnCommon, AdminForthResourceCommon, AdminUser } from '@/types/Common';

const props = defineProps<{
    column: AdminForthResourceColumnCommon;
    record: any;
    meta: any;
    resource: AdminForthResourceCommon;
    adminUser: AdminUser
}>();
</script>

Using 3rd-party npm packages in the components

To install 3rd-party npm packages you should create npm package in the custom directory:

cd custom
npm init -y

👆 Note: for better development experience we recommend to create file custom/tsconfig.json with the following content:

{
  "compilerOptions": {
    "baseUrl": ".",
    "paths": {
      "@/*": [
        "../node_modules/adminforth/dist/spa/src/*"
      ],
      "*": [
        "../node_modules/adminforth/dist/spa/node_modules/*"
      ],
      "@@/*": [
        "."
      ]
    }
  }
}

And simply do `npm install` for the package you need:

```bash
npm install <some package> --save-dev

Pre-made renderers

Though creating custom renderers is super-easy, we have couple of pre-made renderers for you to use.

CompactUUID

If you have a UUID column which you want display in table in more compact manner, you can use CompactUUID renderer.

./resources/apartments.ts

import { randomUUID } from 'crypto';

  ...
  columns: [
    { 
      name: 'id', 
      primaryKey: true,
      showIn: ['filter', 'show'],
      showIn: ['list', 'filter', 'show'],
      fillOnCreate: ({ initialRecord, adminUser }) => Math.random().toString(36).substring(7),
      fillOnCreate: ({initialRecord}: any) => randomUUID(),
      components: {
        list: '@/renderers/CompactUUID.vue'
      }
    }
  ...

Country Flag

Renders string fields containing ISO-3166-1 alpha-2 country codes as flags (e.g. 'US', 'DE', 'FR', etc.)

./resources/apartments.ts

  columns: [
    ...
    {
      name: 'country',
      components: {
        list: '@/renderers/CountryFlag.vue'
      },
      ...
    }

You can also show country name after the flag:

./resources/apartments.ts

  columns: [
    ...
    {
      name: 'country',
      components: {
        list: {
          file: '@/renderers/CountryFlag.vue',
          meta: {
            showCountryName: true
          }
        }
      },
      ...
    }

Human Number

It formats large numbers into a human-readable format (e.g., 10k, 1.5M) and supports localization for different number formats.

./resources/apartments.ts

  columns: [
    ...
    { 
      name: 'square_meter', 
      label: 'Square', 
      minValue: 1,  // you can set min /max value for number fields
      maxValue: 100000000,
      components: {
        list: {
          file: '@/renderers/HumanNumber.vue',
        }
      }
    },
    {
    ...

URL

If your field has absolute URLs as text strings you can use URLs renderer to render them as clickable links.

./resources/anyResource.ts

  columns: [
    ...
    {
      name: 'url',
      components: {
        list: '@/renderers/URL.vue'
      },
    ...

Relative Time

To format your date fields to display the elapsed time, you can utilize the RelativeTime renderer.

./resources/anyResource.ts

  columns: [
    ...
    {
      name: 'created_at',
      components: {
        list: '@/renderers/RelativeTime.vue'
      },
    ...
