Sample configuration - relation features and relation metadata dialog - SysAdmin

In censhare, you can define relation properties for asset relations. When a relation is created between two assets, and a property is configured for the respective relation type, users can select or enter a value. Learn more about the configuration of the UI dialog of relation properties in censhare Web.

Context

In the censhare data model, relation properties are stored as features and child elements of relations.

Introduction

The censhare data model provides the possibility to add properties to Asset relations. Asset relations are stored as independent data objects in a separate table of the database. Asset relations are referenced in the source and the target asset with the <child_asset_rel/> and the <parent_asset_rel/> element, respectively. An asset relation property belongs to the Asset relation object, not to the child or parent asset. However, asset relations cannot be edited directly, but only on the asset page of the child or parent asset. Likewise, asset relation properties are managed there in the respective widgets.

Asset relations properties can be qualifying or quantifying. For example, in an author relation, the type of author can be qualified; or in a budget receiver relation, the allocated budget can be quantified. Relation properties are configured similar to asset features in the Master data/Features table of the censhare Admin Client.

From the user's perspective, asset relation properties can only be added, when an asset relation has been created. This article decsribes how to configure the dialogs for asset relation properties in the Single relation widget, the Multi relation widget and in the Properties widget. For each configuration, an example is given.

The metadata dialog provides the data model and UI controls for the users to edit the relation metadata. It is stored in a Dialog asset. When you create a dialog using the Relations widget configuration (Single- or Multi-relations widget), censhare by default assignes the usage key "censhare:meta-data-relation-dialog-definition" to the dialog asset. This tells censhare that the dialog is to be used for an asset relation. As the metadata are stored in the relation and not in the related assets, they cannot be edited like asset metadata. However, relations cannot be displayed in censhare Web on a page like assets. They are displayed and managed through Relations widgets. These can be placed on either of the assets related to each other. For example, Widget 1 shows Widget 2, which is assigned to it in a "placement" relation. The relation from Widget 1 to Widget 2 indicates the child direction. Therefore, it is shown as "Placements". On the other hand, Widget 2 displays the same relation to Widget 1 as "Placed in". The relation metadata can be edited in both assets in the respective widgets, if configured accordingly.

Create a relation property feature

Note: This step is carried out in the censhare Admin Client.

Configure a relation property feature as follows:

1. Open the Master data/Features table.

2. To create a new feature, click 

   

    .

3. Fill in the respective fields. In the Target object field, select Asset relation. The configuration options for a feature are vast and cannot be covered in this description. For a comprehensive documentation of features read Create a new feature. For an example, see the section below.

4. To save the feature, click OK.

Example: Type of author property

This property can be used with the Author relation (ID: user.author.). The Author relation assigns a Person resource to an article or image asset. The Type of author property characterizes the author relation as Main author, Co-author or Publisher. For that purpose, the feature is configured as Value list and the respective values are stored in the feature definition. However, relation properties can be of any value type. The configuration of these value types - and the configuration of the respective metadata dialogs - is different.

In the Create new: Feature dialog, enter the following values:

Note: The table only shows the mandatory and relevant fields for this configuration.

Scroll down to the Values section and enter the values according to the following table:

Save the feature. For the following configuration steps, you need the Trait key and Property key of this feature.

Create a relation metadata dialog asset

Note: This step is carried out in censhare Web.

Relation metadata dialog assets provide the dialog elements that allow users to edit the asset relation property. The relation metadata dialog uses standard HTML and the <cs-metadata-row/> directive.

To create and configure a relation metadata metadata dialog asset:

1. Create a Module / Dialog asset. In the dialog, enter the values as follows:

2. Enter a name. We recommend to use the name convention "[relation property] relation metadata dialog".

3. Enable the resource.

4. In the Key field, enter a resource key. 

5. In the Usage field, select Relation meta data dialog definition.

6. To save and create the asset, click OK.

7. In the Overview tab, edit the Dialog properties widget and add the Trait key of the feature you created in the first step.

8. To save the changes to the widget and close the dialog, click OK.

9. Go to the Editor tab, select the MIME type HTML and click Create file.

10. In the editor, enter the HTML snippet with the <cs-metadata-row/> directive that retrieves the data from the feature you created in the first step.

For more information about the <cs-metadata-row/> directive, see censhare metadata directives. Fore an example see the following section.

Example: Type of author relation metadata dialog

This relation metadata dialog works with the Type of Author feature created above. Configure the Dialog asset as follows:

<div class="cs-grid-wrapper"> 
   <div class="cs-grid-cell-2of3">    
      <cs-metadata-row 
 property="relation.traits.origin.authorType" />
   </div>
</div>

Save the Dialog asset. For the following configuration steps, you need the Resource key of this asset.

Single relation widget with relation property dialog

Note: This step is carried out in censhare Web

This widget can be placed on the asset page of an Article asset (parent) or Person asset (child). The proper direction must be chosen in the widget configuration. If placed on Article asset pages, users can assign a Person asset as author of the article. If placed on Person asset pages, users can assign Article assets of which the person resource is the author. The configuration and usage of the relation property dialog is identical for both ways.

Proceed as follows:

1. Open the asset page an go to the tab where you want to place the widget.

2. Switch to the Developer mode of censhare Web.

3. In the page actions menu, select Add widget type.

4. In the Add widget dialog, select Asset list based on related assets and click OK.

5. Open the widget actions menu and select Configure widget.

6. For the Generic configuration section, see Generic widget configuration.

7. In the Relation or reference section, select the asset relation type, direction and the further options.

8. In the Edit relation metadata section, select the Relation dialog asset created in the previous step from the Template list.

   Tip: You can also create the Dialog asset (see previous step) or edit the dialog snippet and settings of the Dialog asset by clicking Edit template.

9. Configure the Add relation and Asset picker options.

10. To save the configuration, click OK.

Example: Authors widget and author type dialog

See the example configuration for the Multi relation widget below.

Multi relation widget with relation property dialog

Note: This step is carried out in censhare Web.
