Dependent Fields only work on forms???

[matthewjumpsoffbuildings]

I am trying to implement Dependent Fields and it seems to be the case that dependsOn() only gets called when in create or update views?

Is there no way to make this work on detail views? I was hoping to simply show/hide certain fields based on the value of another field, but it seems like this wont work? Or am I missing something

I don't know if you still need the answer, but here it goes.

DependsOn is for forms only as far as I can see, if you want to conditionally hide fields you could use the $this->when(...) helper in the Resource fields method. Below is an example how this works, and removes the fields if there value is empty. Of course you could specify any other field for the check.

    public function fields(NovaRequest $request)
    {
        return [
            Text::make(__('Action Name'), 'name', fn ($value) => __($value))
                ->showOnPreview(),

            BelongsTo::make(__('Action Initiated By'), 'user', User::class)
                ->filterable()
                ->showOnPreview(),

            MorphToActionTarget::make(__('Action Target'), 'target')
                ->showOnPreview(),

            Status::make(__('Action Status'), 'status', fn ($value) => __(ucfirst($value)))
                ->loadingWhen([__('Waiting'), __('Running')])
                ->failedWhen([__('Failed')]),

            // See here!!!
            $this->when(! empty($this->original), fn () => KeyValue::make(__('Original'), 'original')
                ->showOnPreview()),

            $this->when(! empty($this->changes), fn () => KeyValue::make(__('Changes'), 'changes')
                ->showOnPreview()),

            $this->when(! empty($this->exception), fn () => Textarea::make(__('Exception'), 'exception')
                ->showOnPreview()),

            DateTime::make(__('Action Happened At'), 'created_at')
                ->showOnPreview(),
        ];
    }
