CollectionType Field

Hey rafaelmansilha!

Sorry for my extra slow reply! Yea, I think I understand what you're asking. The answer is: maybe :). y You probably do "really need to create a FormType for it"... but avoiding it may be possible.

When you render a form page in EasyAdmin, the form class is actually this one - https://github.com/EasyCorp/EasyAdminBundle/blob/1.x/src/Form/Type/EasyAdminFormType.php - it's a super-dynamic form type that builds itself based on the entity and your admin options. So, in theory, you could create a form with this, pass in whatever entity you want with an "entity" option, and it will build itself. And then you could embed it. It would look something like this inside of your "main" form type:

$builder
            ->add('genusScientists', CollectionType::class, [
                'entry_type' => EasyAdminFormType::class,
                'entry_options' => [
                    'entity' => GenusScientist::class
                ],
                'allow_delete' => true,
                'allow_add' => true,
                'by_reference' => false,
            ])

Will that work? I have no idea :). But now you have me interested ;). Let me know if you try this and whether it works or not.

Cheers!

Hi !

I tried your method, but it missing the 'view' option in the 'entry_option'. What should we add in this field ?

Thank you in advance for your help !

Hey Edouard Pihet

By looking at this class https://github.com/EasyCorp... I understand that the view option contains the data you defined for such entity and view (create or edit). I find it difficult to extend so I suggest to create your own FormType, it would be cleaner and easier

Cheers!

Hey Alessandro D.

EasyAdmin fully relies on the Symfony Form component, so you can do the exact same thing EasyAdmin forms as you would do with "normal" forms. What you need to do is to specify the "choice_label" option (Docs: https://symfony.com/doc/current/reference/forms/types/entity.html#choice-label)

easy_admin:
    entities:
        Genus:
            form:
                fields:
                    -
                        property: 'genusScientists'
                        type: 'collection'
                        type_options:
                            choice_label: 'some_property_field"

I hope it helps :)
Cheers!

Hi Diego,
I have tried what you suggested, but I get the following error:
"The option "choice_label" does not exist".
Here is my code:

`

        form:
            fields:
                - title
                - revision
                - { property: 'createdAt', type: 'datetime', type_options: { widget: 'single_text' } }
                - author
                -
                    property: 'usedBy'
                    type: 'collection'
                    type_options:
                        choice_label: 'surname'
                - tags
                -
                    property: 'path'
                    label: 'Upload Script'
                    type: 'file_upload'
                    type_options: { upload_dir: public/screenplays }
                - active

`

If I change all the block for 'usedBy' from this to normal '-usedBy' I do get the dropdown, but only the name is displayed

Hey Alessandro D.

Oh, sorry my bad, instead of specifying type: collection, use entity
Docs about EntityType: https://symfony.com/doc/current/reference/forms/types/entity.html#basic-usage

Then, you will be able to specify its choice_label attribute. Let me know if it worked :)

Hi Diego,
That is great. It works like a charm.

Thanks a lot. I can't believe I actually spent an entire evening trying to figure that out. !!! :(

Thanks again.
Alessandro

I hear you man. Symfony Forms are complex but the documentation is great. Every time I'm in doubt I go to the docs and check for any option that may fit my needs.

Cheers!

Hey Kaizoku!

Hmm. So, it sounds like there are two things going on: the HTML5 validation doesn't work AND the server-side validation also does not work. Is that right? These sound like similar systems, but actually they are quite separate.

First, about the HTML 5 validation, I see that you have 'required' => true for your "name" and "language" fields. If you look in the HTML for those fields, do you see a required attribute or not?

Second, about the server-side validation, you may need to add the @Valid constraint above the files property on your entity so that the validation applies to this sub-entity.

Let me know if either of these things helps!

Cheers!

First of all thank you so much Ryan for your answer.

> do you see a required attribute or not?

nope ! So maybe this an issue with the easy_admin form theme file ?

> you may need to add the @Valid constraint above the files property on your entity

yep ! I added validation constraint in the entity and it's now working. At least there is doctrine exception no more.

Don't bother about the HTML5 (unless you know why) since there is form validation it's good enough.

Hey Kaizoku!

> nope ! So maybe this an issue with the easy_admin form theme file ?

Hmm, maybe - I'm not sure. I would look click on the form icon on the web debug toolbar (the clipboard icon), select one of the fields that should be required, and see if the "required" option and "required" view variables are indeed set correctly.

That will at least give you something to check out ;).

Cheers!

Hey Geoffrey M.!

Actually, this is also one of my favorite features of Sonata! Unfortunately, it's not something that exists in EasyAdminBundle :/. So, it would need to be added custom :/ - no easy way! If you have enough of these things, then using Sonata starts to make more sense.

Cheers!

Hey Roberto S.

When you try to add a new photo to a shop, don't you get any error message ? try checking the logs, or if you click in the profiler bar, there is a section of "Requests", where you can check older requests, I believe this "add photo action" is handled via AJAX, maybe you could find out what's going on in there.

Cheers!

The error is:

Expected value of type "AppBundle\Entity\Shop" for association field "AppBundle\Entity\Picture#$shop", got "string" instead.

The request isn't via AJAX :(

Hey Roberto,

Hm, it's weird. Are you sure it's directly related to EasyAdminBundle? Please, make sure you don't call "$picture->setShop('some-string');" manually somewhere in your code. Also, could you show us your easy_admin configuration for Shop and Picture entities?

Cheers!

Thanks Victor, I found the problem, check above.

I've identified the problem.

My Entity "Picture" doesn't initialize the "Shop" field so I've changed the field "Shop" in my PictureEmbeddedForm to 'JavierEguiluz\Bundle\EasyAdminBundle\Form\Type\EasyAdminAutocompleteType' because I've more than 30.000 shops. But it doesn't work when I add new Pictures, only to update or delete.

How can I initialize the "Shop" field of "Picture" entity when I clic on "add new item" on the Collection?

I don't really need a select field for that, It's enough with a hidden field to save the relationship.

Thanks for your help.

Problem solved!!!

I forgot to add $foto->setShop($this); on addPicture method.

public function addPicture(Picture $picture {
$foto->setShop($this);
return $this->pictures->add($picture);
}

Thanks!

Ohh, so the problem was that you forgot to setup the relationship when adding a picture. Good job debugging the problem, the part of the error message "got string instead" confused me.

Cheers!
