FileUploadField

FileUploadField component allows you to upload a file and save it to an entity attribute as a byte array.

The component can contain a caption, a link to the uploaded file, and an upload button. When the upload button is clicked, a standard OS file picker window is shown, where the user can select a file.

Component’s XML-name: fileUpload.

Basics

In the example below, the document attribute of the Person entity has the byte array type.

@JmixEntity
@Table(name = "UIEX1_PERSON")
@Entity(name = "uiex1_Person")
public class Person {
    @JmixGeneratedValue
    @Column(name = "ID", nullable = false)
    @Id
    private UUID id;

    @Column(name = "STATUS")
    private java.lang.Boolean status;

    @InstanceName
    @Column(name = "NAME", nullable = false)
    @NotNull
    private String name;

    @Column(name = "DOCUMENT")
    private byte[] document;

}

<data>
    <instance id="personDc"
              class="ui.ex1.entity.Person">
        <fetchPlan extends="_base"/>
        <loader/>
    </instance>
</data>
<layout spacing="true">
    <form id="form" dataContainer="personDc">
        <column width="350px">
            <textField id="nameField"
                       property="name"/>

            <fileUpload id="documentField"
                        showFileName="true"
                        property="document" />
        </column>
    </form>
</layout>

To store the file in the file storage and link to the entity as FileRef, use the FileStorageUploadField component.
