Editing Demo VisualData/CRUD

The following demonstrates the creation of a  [https://en.wikipedia.org/wiki/Create,_read,_update_and_delete CRUD] (create, read, update, delete) interface performed through a button opening a popup form, a <code>pagepropertiesquery</code> 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 ([[PagePropertiesSchema:Task]]) based on the data of the page with value <code><nowiki>{{{pagetitle}}}</nowiki></code>, where <code><nowiki>{{{pagetitle}}}</nowiki></code> is the title of the article related to each row of the generated table. (see the [https://www.mediawiki.org/wiki/Extension:PageProperties#Queries docs] for other parameters)

The template is associated to the column "action" using the following wikitext 
<pre>
template?action=Task action
</pre>
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 <code>target-slot = main</code> that instructs the form to save the json data to the main slot of the target article, as you can see [[CRUD/12|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 [https://www.mediawiki.org/wiki/Extension:VEForAll Extension:VEForAll] in the comments field.

 
{{#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 =

|validate-button-text =
}}




{{#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 [[Special:ManageSchemas|Schema builder]])


2) parser function for the form popup

<pre>
{{#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 =
}}
</pre>


3) Parser function for the table

<pre>

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

</pre>


4) template [[Template:Task action]], containing another pageproperties form, as mentioned

5) The extension [https://www.mediawiki.org/wiki/Extension:IDProvider IDProvider] triggered from an hidden input in the same schema, and then used as <code>pagename-formula</code>

6) The extension [https://www.mediawiki.org/wiki/Extension:VEForAll VEForAll] in order to display [https://www.mediawiki.org/wiki/Extension:VisualEditor VisualEditor] in the textarea
