[Ed B.]

OK, I think I have solved this.



As I am imitating the model "Category" I should be putting only one image for my entity (and this is enough for my purpose).


So here is how it goes : in my module, aside from Main.php, I have 7 php files and one twig file. The entity is called "Author", module is "Librairie" and vendor name is EdB.


The files are:



Controller file Controller/Admin/AuthorEdit.php
Page view file View/Page/Admin/AuthorEdit.php which calls the twig file
the twig file page/myentity_edit/body.twig which calls the input forms, which is
View/Model/Author.php
View/Form/Model/Author.php


and the definition of entities

Model/Author.php
Model/Image/Author/Image.php
and the path to the image storage
Model/Repo/Image/Author/Image.php


The relevant part of the codes are


the definition of image property and getter and setter in Model/Author.php

    /**
     * One-to-one relation with category_images table
     *
     * @var \XLite\Module\EdB\Librairie\Model\Image\Author\Image
     *
     * @OneToOne  (targetEntity="XLite\Module\EdB\Librairie\Model\Image\Author\I
mage", mappedBy="author", cascade={"all"})
     */
    protected $image;

...
...


    /**
     * Get image
     *
     * @return \XLite\Module\EdB\Librairie\Model\Image\Author\Image
     */
    public function getImage()
    {
        return $this->image;
    }


    /**
     * Set image
     *
     * @param \XLite\Module\EdB\Librairie\Model\Image\Author\Image $image Image 
OPTIONAL
     *
     * @return void
     */
    public function setImage(\XLite\Module\EdB\Librairie\Model\Image\Author\Imag
e $image = null)
    {
        $this->image = $image;
    }

    /**
     * Check if category has image
     *
     * @return boolean
     */
    public function hasImage()
    {
        return null !== $this->getImage();
    }

(OK, I was too lazy to change some commented out text, but this shouldn't cause the trouble). The definition of the image entity in Model/Image/Author/Image.php

namespace XLite\Module\EdB\Librairie\Model\Image\Author;

/**
 * Author
 *
 * @Entity
 * @Table  (name="author_images")
 */
class Image extends \XLite\Model\Base\Image
{
    /**
     * Relation to a author entity
     *
     * @var \XLite\Module\EdB\Librairie\Model\Author
     *
     * @OneToOne   (targetEntity="XLite\Module\EdB\Librairie\Model\Author", inve
rsedBy="image")
     * @JoinColumn (name="author_id", referencedColumnName="author_id", onDelete
="CASCADE")
     */
    protected $author;
...
...
   /**
     * Set author
     *
     * @param \XLite\Module\EdB\Librairie\Model\Author $author
     * @return Image
     */
    public function setAuthor(\XLite\Module\EdB\Librairie\Model\Author $author =
 null)
    {
        $this->author = $author;
        return $this;
    }

    /**
     * Get author
     *
     * @return \XLite\Module\EdB\Librairie\Model\Author 
     */
    public function getAuthor()
    {
        return $this->author;
    }

(Omitted lines are about alternative texts)


and the image uploader definition in

View/Model/Author.php

        'image' => array(
            self::SCHEMA_CLASS    => 'XLite\View\FormField\FileUploader\Image',
            self::SCHEMA_LABEL    => 'Image',
            self::SCHEMA_REQUIRED => false,
        ),

as well as the path setup in Model/Repo/Image/Author/Image.php

namespace XLite\Module\EdB\Librairie\Model\Repo\Image\Author;

class Image extends \XLite\Model\Repo\Base\Image
{
    /**
     * Returns the name of the directory within 'root/images' where images store
d
     *
     * @return string
     */
    public function getStorageName()
    {
        return 'author';
    }
}

I hope this helps people having similar issues.
