Demo VisualData/CRUD

The following demonstrates the creation of a CRUD (create, read, update, delete) interface performed through a button opening a popup form, a visualdataquery parser function that creates the table, and a template, namely Template:Task_action, rendered within the column "action", holding another form that edits the same schema (VisualDataSchema:Task) based on the data of the page with value {{{pagetitle}}}, where {{{pagetitle}}} is the title of the article related to each row of the generated table. (see the docs for other parameters)

The template is associated to the column "action" using the following wikitext

template?action=Task action

and all the properties of the row, as well as the article title, are available as named parameters.

The form also demostrates the use of the option target-slot = main that instructs the form to save the json data to the main slot of the target article, as you can see here. Such data can then be edited through the edit button in the action column, through the tab "Edit semantic" in the target article, or even manually through "edit source" in the target article, and the changes will be reflected in the table below.

The form also shows the integration of Extension:VEForAll in the comments field.

form is loading...

{{#pagepropertiesquery: CRUD/~ |schema=Task |?assignee |?extension |?status |?action |template?action=Task action |format=datatable }}

Here are the components to implement it.

1) Json-schema describing the form: PagePropertiesSchema:Task (created through the Schema builder)

2) parser function for the form button

{{#pagepropertiesform: Task
|title = Task
|action = create
|edit-page = 
|return-page = CRUD
|view = popup
|popup-size = large
|css-class =
|pagename-formula =CRUD/<id-increment>
|target-slot = main
|edit-freetext = false	
|edit-categories = false
|edit-content-model = false
|default-categories = 
|default-content-model = wikitext
|layout-align = top
|popup-help = true 
|submit-button-text =
|layout = tabs
|validate-button-text =
}}

3) Parser function for the table

{{#visualdataquery: [[CRUD/~]]
|schema=Task 
|?assignee
|?extension
|?status
|?action
|template?action=Task action
|format=datatable 
}}

4) template Template:Task action, containing another pageproperties form, as mentioned called from the query for each row

5) The templates Template:Extensions_list and Task_status_list (actually not a template) used in the form's dropdowns

6) The extension IDProvider triggered from an hidden input in the same schema, and then used as pagename-formula

7) The extension VEForAll in order to display VisualEditor in the textarea

Of course the extension VisualData, Semantic MediaWiki is not required.
