Related resource index view.

[philipbaginski]

Hi everyone!

What is my question: I have a resource X related to Y by belongs to many relation. On detail view of resource Y I can see X resource index table with its fields, and in addition pivot fields. That is fine, but resource X has many fields on index view I don't want to display when index view is displayed via relationship. Right now I have two options: Create extra resource just for displaying index view of X resource via relationship. Second, in resource X use fieldsForIndex and in addition use

​ ->hideFromIndex(function (ResourceIndexRequest $request) { return $request->viaRelationship(); }), ​
We have a set of fields for many cases like fieldsForIndex, fieldsForDetail, etc., but there is no fieldsForRelationship.

What do you think about it?

You can always create field macro for reusable/repeating filters.

Are you sure it's a good idea for related resource index view?

[crynobone]

I don't have the use case to code it but $request->viaRelationship() and $request->viaManyToMany() is reliable methods to determine such usage.

So, my case:

Resource Trainer, index view fields.

​```

/**
 * Get the fields displayed by the resource - index view.
 *
 * @param  \Laravel\Nova\Http\Requests\NovaRequest  $request
 * @return array
 */
public function fieldsForIndex(NovaRequest $request)
{
    return [
        Text::make(__('Trainer'), 'name')
            ->sortable(),
        BelongsTo::make(__('Country'), 'country', Country::class)
            ->sortable()
            ->viewable(false)
            ->hideFromIndex(function (ResourceIndexRequest $request) {
                return $request->viaRelationship();
            }),
        Text::make(__('Phone'), fn () => $this->trainerProfile->phone ?? null)
             ->hideFromIndex(function (ResourceIndexRequest $request) {
                 return $request->viaRelationship();
             }),
        Email::make(__('Email'), 'email')
            ->sortable()
            ->hideFromIndex(function (ResourceIndexRequest $request) {
                return $request->viaRelationship();
            }),
        Text::make('ID', 'id')
            ->sortable()
            ->hideFromIndex(function (ResourceIndexRequest $request) {
                return $request->viaRelationship();
            }),
        BelongsToMany::make(__('Players'), 'players', Player::class)
            ->fields(function () {
                return [
                    Date::make(__('From'), 'from_date'),
                    Date::make(__('Until'), 'to_date'),
                    Textarea::make(__('Notes'), 'notes')
                        ->rows(2),
                    Boolean::make(__('Is Active'), 'is_active')
                        ];
                    })
    ];
}

​```

, and via relationship on the index view I want to see only trainer name. Right now to every field I don't want to see on the index via relationship I have do add

​ ->hideFromIndex(function (ResourceIndexRequest $request) { return $request->viaRelationship(); }), ​

to hide them. So, my question is how to make fieldsForViaRelationship? :-)
