3.7.3. User Preferences

Steps to implement the feature

In order to implement this feature take the following steps:

  1. Add the object with name UserPreferences to model.xml by copying the content of user-preferences-object.xml. into model.xml.

    Listing 3.15 model.xml
     1<model>
 2        <package>
 3                <metadata>
 4
 5                </metadata>
 6
 7                <object name="UserPreferences">
 8
 9                </object>
10        </package>
11</model>

    Note

    If you are reading this documentation on paper you can find the file in the next section Files.

  2. Add the highlighted code to the package metadata in model.xml:

    Listing 3.16 model.xml
     1<model>
 2        <package>
 3                <metadata>
 4
 5                        <owner>
 6                                <keyword>Owner</keyword>
 7                                <role>USER</role>
 8                                <url.prefix>owner</url.prefix>
 9                        </owner>
10                </metadata>
11        </package>
12        ...
13</model>

  3. Add the highlighted line to pattern.xml:

    Listing 3.17 pattern.xml
    1<pattern>
2
3        <external.file id="libJH/jhipster620_angular800/frontend/webapp/app/account/preferences_route_ts.xml" skip="false" />
4
5</pattern>

  4. Generate the Runtime Model with the Runtime Model buildset.

  5. Generate all

  6. Have Liquibase create the UserPreferences table upon startup of the application:


Copy the two changeSets in the generated changeset-create-table-user_preferences.xml to the end of
[project]\[backend]\src\main\resources\config\liquibase\liquibase-alters-changeLog.xml
for the creation of the UserPreferences table.

Listing 3.18 liquibase-alters-changeLog.xml
1<?xml version="1.1" encoding="UTF-8" standalone="no"?>
2<databaseChangeLog>
3        ...
4        [insert changesets here]
5</databaseChangeLog>

In liquibase-alters-changeLog.xml replace referencedTableName=”user” with referencedTableName=”jhi_user” in the highlighted line:

Listing 3.19 liquibase-alters-changeLog.xml
 1<addForeignKeyConstraint
 2        baseColumnNames="user_id"
 3        baseTableName="user_preferences"
 4        constraintName="fk_user_preferences_user_id_to_user"
 5        deferrable="false"
 6        initiallyDeferred="false"
 7        onDelete="NO ACTION"
 8        onUpdate="NO ACTION"
 9        referencedColumnNames="id"
10        referencedTableName="user"
11/>

  1. Adjust the custom file generated for the user preferences Angular component:

    • [project]-metafactory\src\snippets\[frontend]\owner\edit\edit-component-userpreferences.ftl

      Add the parameter this.id to the getMyUserPreferencesEditDto call:

      Listing 3.20 edit-component-userpreferences.ftl
      1<#assign onInitCode>
2ngOnInit() {
3        // EDIT: retrieve the instance of this UserPreferences
4        this.subs.sink = this.ownerUserPreferencesService.getMyUserPreferencesEditDto(this.id).subscribe((data: OwnerUserPreferencesEditDto) => {
5                this.ownerUserPreferencesEditDto = data;
6                this.buildFormGroup();
7        });
8}
9</#assign>

  2. Add the project specific user preferences to model.xml:

    User preferences can be added to attributes and references.

    1. Attributes

      For each attribute of an object that you would like to be initially set to a user preference, perform the following steps:

      1. Add <user.preferences /> to the existing attribute.

      2. Add a new attribute to the UserPreferences object with the name [object.name?uncap_first][attribute.name?cap_first], e.g. hourAmount.

      3. Add metadata to the new attribute in the UserPreferences object:

        Listing 3.21 model.xml
        1<object name="UserPreferences">

<<<<<<< HEAD

<metadata>
<edit.owner.row2>

<col1>label</col1> <col1.colspan>3</col1.colspan> <col2>widget</col2> <col2>

<colspan>3</colspan>

</col2>

</edit.owner.row2>

</metadata>

</attribute>

</object>

  1. Add code to [project]-metafactory\src\snippets\[frontend]\owner\edit\edit-template-userpreferences.ftl to generate the rendering of the newly added user preference.

    Listing 3.22 edit-template-userpreferences.ftl for rendering an attribute
    <@generalMaterial.renderField false ''>
        <@generalMaterial.renderFieldLabel userPreferences.[attribute.name] metadataKey tsUserPreferences />
        <@generalMaterial.renderFieldBody wrapDivField=true wrapSecondDivField=true>
                <@am.renderFormGroup userPreferences.[attribute.name]>
                        <@am.renderEdit userPreferences.[attribute.name] metadataKey tsUserPreferences />
                </@am.renderFormGroup>
        </@generalMaterial.renderFieldBody>
</@generalMaterial.renderField>

    Replace [attribute.name] with the attribute name as defined in the UserPreferences object, e.g. hourAmount.

  2. Add a changeSet for the creation of the newly added project specific user preferences attribute at the end of liquibase-alters-changeLog.xml.

  1. References

    For each reference of an object that you would like to be initially set to a user preference, perform the following steps:

    1. Add <user.preferences /> to the reference that you would like to be initially set to a user preference.

    2. Add a reference to the UserPreferences object with the name [object.name?uncap_first][reference.name?cap_first], e.g. hourTask.

    3. Add metadata to this reference:

      Listing 3.23 model.xml
      1<object name="UserPreferences">

<<<<<<< HEAD

<metadata>
<edit.owner.row2>

<col1>label</col1> <col1.colspan>3</col1.colspan> <col2>widget</col2> <col2>

<colspan>3</colspan>

</col2>

</edit.owner.row2>

</metadata>

</reference>

</object>

  1. Add code to [project]-metafactory\src\snippets\[frontend]\owner\edit\edit-template-userpreferences.ftl to generate the rendering of the newly added user preference.

<<<<<<< HEAD
caption:

edit-template-userpreferences.ftl for rendering a reference

name:

edit-template-userpreferences.ftl3

<ng-container *ngIf=”parentContext===undefined || parentContext.parentReference!=’[reference.name]’”>
<@generalMaterial.renderField>

<@generalMaterial.renderFieldLabel userPreferences.[reference.name] metadataKey tsUserPreferences /> <@generalMaterial.renderFieldBody wrapDivField=true>

<@am.renderFormGroup userPreferences.[reference.name]>

<@am.renderEdit userPreferences.[reference.name] metadataKey tsUserPreferences />

</@am.renderFormGroup>

</@generalMaterial.renderFieldBody>

</@generalMaterial.renderField>

</ng-container>

Replace [reference.name] with the reference name as defined in the UserPreferences object, e.g. hourTask.

  1. Add a changeSet for the creation of the newly added project specific user preferences reference at the end of liquibase-alters-changeLog.xml.

  1. Generate the Runtime Model with the Runtime Model buildset.

  2. Generate all

  1. Translate User Preferences

    • [project]\[frontend]\src\main\webapp\i18n\en\userpreferences.json

    • [project]\[frontend]\src\main\webapp\i18n\nl\userpreferences.json

  2. Add menu item for User Preferences to the project’s top menu:

    Different projects have different top menu’s. So adding a menu item for User Preferences requires manual addition.

  3. Run the application

3.7.3.2. Developer notes

Important

For projects that do not have a UserPreferences object in model.xml yet, the aim is to generate no user preferences related code.

For projects like AMI that do have a UserPreferences object in model.xml, the aim is to let AMI’s custom patterns/snippets generate all user preferences related code, so no significant outgoing changes should occur.
