README
This module allows you to directly edit the fields of a related has_one
object directly, without having to mess around with GridField
or links to ModelAdmin
. If the related has_one
doesn't exist yet, then this module also creates the object and sets up the relation for you on first write.
This module has been tested editing a has_one
in both a GridFieldDetailForm
and on a generic Page
in CMSMain
.
Requirements
SilverStripe 4.x.
Basic testing has been carried out on 4.0.x-dev. Extensive testing may be required as SS4 becomes more solid.
Usage
To use this module, simply add a field to the CMS fields for your object in your getCMSFields()
method. The name of the field should be HasOneName-_1_-FieldName
.
For example, say you have a has_one
called Show
and that has_one
has a field called Title
you want to edit. You'd add the field TextField::create('Show-_1_-Title', 'Show Title')
.
If you do not require that the outputted name of the field matches the value you supply, you can also use a colon as a separator instead of -_1_-
.
Generating fields with the ProvidesHasOneInlineFields
trait
If you simply want to display all the CMS fields for a related object, you can add the ProvidesHasOneInlineFields
trait to the object. This adds a method which calls getCMSFields()
on your DataObject
and return the FormField
s for that object. Those FormField
s will be converted for use with this module by adding the relation name and separator to their name.
In the owning object, where you want to display the fields, call HasOneEdit::getInlineFields($this, 'my_has_one_name', ['db'])
. This will return the db
subset of fields for adding to the CMS - e.g. you
can display the related object's fields in their own tab by calling $fields->addFieldsToTab('Root.RelatedObject', HasOneEdit::getInlineFields($this, 'Relation', ['db']))
.
This has the advantage of running the entire getCMSFields()
call tree (e.g. updateCMSFields
for any functionality provided via extension) etc. without having to repeat logic
in a lot of places.
You can also implement a method public function provideHasOneInlineFields($relationName)
returning FieldList|FormField[]
to provide a custom interface different
to getCMSFields()
(e.g. just a small subset of fields). In this case, all the field names should be in the form $relationName . HasOneEdit::FIELD_SEPARATOR . $dataObjectFieldName
.
This method will be called by HasOneEdit::getInlineFields
even if your class does not use the ProvidesHasOneInlineFields
trait.
Using with your own form
To add support to your own forms, you need to add the Sunnysideup\HasOneEdit\UpdateFormExtension
extension to your controller and call $this->extend('updateEditForm', $form)
before returning the form to the template. Without this, the fields will not get populated with the values from the has_one
though saving will work.
