Form Builder Microservice (FBMS)

The Form Builder Microservice (FBMS) project is an Apereo uPortal Ecosystem component that brings a Form Builder feature set to the portal. This Git repo contains the sources for the back-end elements of this solution; it bundles the user interface in the build process as a web component packaged in a webjar. This web component is developed independently as the uPortal-contrib/form-builder project. Front- and back-end communicate exclusively through REST APIs.

FBMS is developed with the following Java Platform technologies:

• Spring Boot
• Spring Security
• spring-data-jpa
• Hibernate
• Jackson (JSON)

Running This Project

Running in a Development Environment

Use the Spring Boot Gradle Plugin to execute this project in a local development environment.

$ ./gradlew fbms-webapp:bootRun

Using FBMS in uPortal

FBMS does not need uPortal to run, but can be integrated with uPortal version 5.1 or higher.

Step One: Bundling FBMS

In uPortal-start, add an overlays/fbms/build.gradle file with the following contents:

import org.apereo.portal.start.gradle.plugins.GradleImportExportPlugin

apply plugin: GradleImportExportPlugin

dependencies {
    runtime "org.jasig.portal.fbms:fbms-webapp:${fbmsVersion}@war"
    compile configurations.jdbc
}

war {
    archiveName 'fbms.war'
}

/*
 * Import/Export Support
 */

import org.apereo.portal.start.shell.PortalShellInvoker

dependencies {
    impexp configurations.jdbc
    impexp 'org.springframework.boot:spring-boot-starter-tomcat:2.0.3.RELEASE' // Version should match FBMS
}

dataInit {
    /*
     * Drop (if present) then create the Hibernate-managed schema.
     */
    doLast {
        File serverBase = rootProject.file(rootProject.ext['buildProperties'].getProperty('server.base'))
        File deployDir = new File (serverBase, "webapps/${project.name}")

        ant.setLifecycleLogLevel('INFO')
        ant.java(fork: true, failonerror: true, dir: rootProject.projectDir, classname: 'org.apereo.portal.fbms.ApereoFbmsApplication') {
            classpath {
                pathelement(location: "${deployDir}/WEB-INF/classes")
                pathelement(location: "${deployDir}/WEB-INF/lib/*")
                project.configurations.impexp.files.each {
                    pathelement(location: it.absolutePath)
                }
            }
            sysproperty(key: 'portal.home', value: project.rootProject.ext['buildProperties'].getProperty('portal.home'))
            arg(value: '--init')
            arg(value: '--spring.jpa.hibernate.ddl-auto=create')
        }
    }
    /*
     * Import database entities located anywhere within the folder
     * specified by 'implementation.entities.location'.
     */
    doLast {
        File serverBase = rootProject.file(rootProject.ext['buildProperties'].getProperty('server.base'))
        File deployDir = new File (serverBase, "webapps/${project.name}")
        String implementationEntitiesLocation = PortalShellInvoker.createGroovySafePath(rootProject.ext['buildProperties'].getProperty('implementation.entities.location'))

        ant.setLifecycleLogLevel('INFO')
        ant.java(fork: true, failonerror: true, dir: rootProject.projectDir, classname: 'org.apereo.portal.fbms.ApereoFbmsApplication') {
            classpath {
                pathelement(location: "${deployDir}/WEB-INF/classes")
                pathelement(location: "${deployDir}/WEB-INF/lib/*")
                project.configurations.impexp.files.each {
                    pathelement(location: it.absolutePath)
                }
            }
            sysproperty(key: 'portal.home', value: project.rootProject.ext['buildProperties'].getProperty('portal.home'))
            arg(value: '--import')
            arg(value: "${implementationEntitiesLocation}/fbms")
        }
    }
}

Also add include 'overlays:fbms' to your settings.gradle file.

Step Two: Publishing a Form with FBMS

Use a SimpleContentPortlet to publish the following HTML markup as a portlet:

<script src="/fbms/webjars/uportal__form-builder/0.1.2/build/static/js/form-builder.js"></script>
<form-builder
  fbms-base-url="/fbms"
  fbms-form-fname="{form.fname}"
  oidc-url="/uPortal/api/v5-1/userinfo">
</form-builder>

Replace {form.fname} with the fname of your form.

Configuration

CORS Support

Browser-based clients for this microservice will often need to run on a different host or port. In these cases, support for CORS is required.

Use the org.apereo.portal.fbms.api.cors.origins application property to specify allowed origins for CORS requests. The default value of this property is http://localhost:8080.

CORS Example

org.apereo.portal.fbms.api.cors.origins=http://localhost:8080

Permissions

Typically authenticated users have permission to read any form, as well as create, read, and update their own responses to forms. (In the future FBMS may support updating responses both by overwriting an existing response and submitting a new response.)

As far as managing forms themselves, there are three types of access:

• createAuthority
• updateAuthority
• deleteAuthority

The createAuthority allows you to create new forms, whereas updateAuthority and deleteAuthority apply to any form that has been previously created.

The default value for each of these authorities is Portal Administrators, which corresponds to the group of the same name in uPortal.

Permissions Example

Use the following properties to assign these permissions to one or more different portal groups:

org.apereo.portal.fbms.security.createAuthority=Portal Administrators, Forms Authors
org.apereo.portal.fbms.security.updateAuthority=Portal Administrators, Forms Editors
org.apereo.portal.fbms.security.deleteAuthority=Portal Administrators

Import/Export Features

Apereo FBMS provides support for importing and exporting data from the console. These features are tremendously useful for provisioning new environments and migrating data.

Initializing the Database Schema

Use the following command to drop (if necessary) and create the Hibernate-managed database tables:

$ ./gradlew assemble fbms-webapp:bootRunDataInit

Importing

Use the following command to import all Form objects serialized into JSON files that are located in the docs/examples directory:

$ ./gradlew assemble fbms-webapp:bootRunDataImport

NOTE: The location of this directory is very likely to change or (even more likely) become a parameter in the future. Check this document for changes.

API Documentation

FBMS provides API documentation based on Swagger. You can access the Swagger client at http[s]://hostname[:port]/swagger-ui.html.
