如何通过category_id列出子类别的名称？

Question

I am trying to list subcategory name by category_id where category_id should be grouped and show all subcategory name of that grouped id. Please see the attached figure shown in below:

In my web page category name shown repeatedly but I want category should be display one and subcategory name should be display. For example:

category name   || subcategory name||
Data Management || pa , roji       ||
Executive       || lov, true       ||

My simple using relationship query is:

TeamSubCategory::with('category')->orderBy('weight')->get();

Answer 1

You could do something like this (semi-pseudo code since you didn't post any of your models or your view):

Controller:

$categories = Category::with('teamsubcategory')->get();

View:

<table>
    @foreach ($categories as $category)
    <tr>
        <td>{{ $category->name }}</td>
        {{-- implode the teamsubcategories and join with a comma and space on the name value --}}
        <td>{{ $category->teamsubcategory->implode('name', ', ') }}</td>
    </tr>
    @endforeach
</table>

Answer 2

Try group by category_I'd. And select group_concat(distinct name) as subcategory_name

Answer 3

using group_concat :

TeamSubCategory::with
->select('*', DB::raw('GROUP_CONCAT(name SEPARATOR ', ') as `name_concatenated`'))
->('category')->groupBy('category_id')->orderBy('weight')->get();
