form->fill()`with Selects?

Anyone know how to use $this->form->fill( [...] ) with Select fields? I need to automatically select something from the dropdown while inside a form action function.

Guess it depends on the select and what the available options are.

My Select looks like this:

                    Select::make('parent_id')->hint('Indicates: /parent/nested/path')
                        ->relationship(
                            name: 'parent',
                            modifyQueryUsing: fn (Get $get, Builder $query) => $query->where('project_id', $get('project_id')),
                        )
                        ->getOptionLabelFromRecordUsing(fn (Category $record) => $record->ancestor_path),

                    Select::make('parent_id')->hint('Indicates: /parent/nested/path')
                        ->relationship(
                            name: 'parent',
                            modifyQueryUsing: fn (Get $get, Builder $query) => $query->where('project_id', $get('project_id')),
                        )
                        ->getOptionLabelFromRecordUsing(fn (Category $record) => $record->ancestor_path),

I thought I could assign the id like:

$this->form->fill([
 'parent_id' => 100,
]);

$this->form->fill([
 'parent_id' => 100,
]);

Ie, you can’t set a select with a preload if the the form fill doesn’t include the the key for the select. But shouldn’t relally be a problem unless the select is a relationship Ok, so you’re assuming that the select options has a key, which It might not have. So it will default to null.

bionaryOP•2w ago

let me look at the hmtl output in console

awcodes•2w ago

If the select is a relationship then that relationship might not exist so you have to handle that.

bionaryOP•2w ago

Yes, I have a relationship there. In google console, I have many parent_id's there.
I tried hardcoding in a value that I can see it there in google console: like this:

 $this->form->fill([
   'parent_id' => 329 ,
]);

 $this->form->fill([
   'parent_id' => 329 ,
]);

But it does not select that item. Maybe the form is reloading at that instance. I've been duped before by the constant livewire magic.

awcodes•2w ago

Right but a relationship select is async so loading in a id of 100 etc doesn’t guarantee that it’s even an option in the select. And without preload() there are 0 options in the select.

bionaryOP•2w ago

yes, that is what I am thinking.

awcodes•2w ago

Basically you are saying that the default should be 100 for the key, but you aren’t guaranteeing that 100 is even a key in the options for the select.

bionaryOP•2w ago

yes

awcodes•2w ago

If that makes sense.

bionaryOP•2w ago

it does

awcodes•2w ago

So just make the select preload with that key and it should be fine.

bionaryOP•2w ago

I thought I could programmatically select the value using Set $set but that is not working in this context

awcodes•2w ago

Right, because it’s a relationship. You can’t tell it to be a default before retrieving a data set. Which is where preload comes into play.

bionaryOP•2w ago

I tried preload()... no good. I think perhaps the problem is because I am calling $this->form->fill() from outside the resource? I am calling it from inside the ->action() of a button/form/modal inside getHeaderActions()

awcodes•2w ago

Preload can define a query on the relationship that includes the defaults.

bionaryOP•2w ago

The rest of the form fields (text input) fill in. okay, let me look at the preload docs

awcodes•2w ago

Maybe you need to access the livewire instance in the action to get the relationship. Hard to say without seeing the actual code.

bionaryOP•2w ago

I do appreciate the help Adam, thank you.

awcodes•2w ago

Just remember that you can always inject the livewire component and get the record from there. Even if if feels gross. We don’t get paid to be pretty. We get paid to make it work.

bionaryOP•2w ago

lol, I was just looking at the livewire instance and "gross" was EXACTLY the word I had in mind! By inject do you mean something like this:
$livewire->data['parent_id'] = 329;

awcodes•2w ago

I was referring to DI, like in the select you can do something like fn($record) => doSomethingwith($record)

bionaryOP•2w ago

It seems to be getting messed up from the relationship on the Select (like you said). I can assign the right value, but since it is a relationship, it's not taking the change.

awcodes•2w ago

But the livewire component is available in any of the fields as an injection/resolution in the call back Right, you just have to get the call backs right.

bionaryOP•2w ago

Since I am working outside the form though might have to do with why it's not accepting the programmatically set value.

awcodes•2w ago

If the select says the options are 1,2,3 but your form fill says default to 4 it’s just not going to work.

bionaryOP•2w ago

yes, I get that That's why I examined the html directly to find an ID that I knew would be there. Then I hardcoded (tried setting that). Just to see if it would work, before things got dynamic

awcodes•2w ago

Also, may not be relevant, but default only works in the create context. In the edit context it’s assumed that the default has already been set during creation.

bionaryOP•2w ago

that makes sense. Just to clarity: I am trying to programmatically set the form from outside the resource. It's a modal from the button in the header on the create page.

awcodes•2w ago

Fair but there’s still a lifecycle

bionaryOP•2w ago

Just for ha-ha's I removed the relationship and added the simplest select options like this:

                        ->options([
                            1 => 'one',
                            2 => 'two',
                        ]),

                        ->options([
                            1 => 'one',
                            2 => 'two',
                        ]),

awcodes•2w ago

And relationships in selects don’t get loaded into the select until it is interacted with, so defaulting it isn’t necessary straight forward

bionaryOP•2w ago

Then tried to set it:

 $this->form->fill([
   'parent_id' => 1 ,
]);

 $this->form->fill([
   'parent_id' => 1 ,
]);

Still doesn't work I think this is a dead end if that simple example doesn't work

awcodes•2w ago

To be fair, I don’t understand setting a form outside a resource. That doesn’t make sense to me.

bionaryOP•2w ago

I am using a button to grab an existing resource from an external API and populate the form.

awcodes•2w ago

Ok, so what is the relation between the api and the select relationship?

bionaryOP•2w ago

So while inside the create page, instead of filling out a form, I want to be able to use existing data from an external source The API sends an array and some of those values are used for various properties for that model. No relationship in a Laravel sense because it's external I can go about this another way and simply create the record on the fly from the index page...without having to fill in the form. it will 100% work, but I was just trying to fill in the form so I could see all the data coming over...like a preview of sorts before creating the model

awcodes•2w ago

Ok, im lost now. Sorry. What does the external api have to do with a select that is a relationship on the local database?

bionaryOP•2w ago

Yeah, this is a tough one...sorry Adam !!! The API is from one of my wordpress websites. and my Filament app manages this website and several others.

awcodes•2w ago

No worries, just trying to understand the issue and it’s just not adding up to me logically.

bionaryOP•2w ago

The select is for getting the heirarchy of the wordpress categories. (parent / child)

awcodes•2w ago

So, you’re trying to use filament to manage a wp install?

bionaryOP•2w ago

Yes, been doing that for years!

awcodes•2w ago

Oh god. That’s a whole diffent beast.

bionaryOP•2w ago

I built a personal system that posts to all kinds of websites 1000s of articles without ever touching wordpress! images, formatting everthing 🙂 it's such a mess and wordpress is the absolute worst...but it all works I tell ya

awcodes•2w ago

I admire what you are doing, but that’s not an easy thing to do.

bionaryOP•2w ago

I did it years ago. it runs one of my businesses I can create categories but was going to implement a way to import/link exisiting categories. But like I said, I can do this no problem from the index. It will all happen once the dropdown is selected and I won't get to see the form filled, no big deal. Well I just talked myself into refactoring it that way! Thanks Adam

Dennis Koch•2w ago

Yay, I'm not alone. Not posting to WordPress, but building some kind of "MainWP" in Filament

bionaryOP•2w ago

@Dennis Koch oh sweet. Working with Wordpress is a nightmare. Doing the simplest things (for example: adding images) will make anyone want to jump off a building. I had to build a custom Wordpress plugin just to handle areas where the awful, antiquated and often incomplete WordPress API documentation falls short.

Dennis Koch•2w ago

Building the API plugin was the most fun I ever had with WordPress 😅 Even though it's a lot of pain sometimes. I want to update my plugins via API: "Oh, nice there's a function. Seems easy" ... "Oh that doesn't work" ... "Oh, it only works when I require a different file, but it doesn't tell my and doesn't throw an error"

bionaryOP•2w ago

@Dennis Koch sounds about right
