Help:ChangeContentModel/pt-br



A página Especial:ChangeContentModel pode ser usada para mudar o "modelo de conteúdo" de uma página. Um modelo de conteúdo, de forma mais ampla, é um formato ou tipo de uma página específica numa wiki. Por padrão o modelo de conteúdo de uma página é wikitext, um formato de texto formatado que faz uso da marcação wikitexto. Modelos de conteúdo usados nos projetos Wikimedia incluem css e javascript para armazenar código, wikibase-item para entradas no Wikidata, e Campaign no Wikimedia Commons para carregar campanhas como Wiki Loves Monuments. Uma lista de modelos de conteúdo estão disponíveis em content handlers. Informações mais técnicas estão disponíveis em Manual:ContentHandler.

All actions are logged to Special:Log/contentmodel, with a convenient "revert" link to undo changes if necessary. Users must have the  permission to be able to change content models. On Wikimedia projects this permission is currently granted to sysops.

Contexto
Tradicionalmente, os únicos tipos de páginas que poderiam ser criadas na MediaWiki eram páginas de wikitexto: documentos de texto rico escritos em marcação wikitexto. Isso é aceitável para entradas de enciclopédia na Wikipédia, mas é insuficiente para conteúdos de outros tipos, como blocos de códifo fonte, conteúdo de data estruturada, ou fluxo de trabalhos complexos.

With the advent of the Wikidata project (and the Wikibase extension) in 2012, the ContentHandler branch was developed to allow the creation of pages other than wikitext documents. As of MediaWiki 1.21, ContentHandler is a part of the core MediaWiki software.

Some generic content models include those meant for storing and presenting source code, but they can also be used to create customized editing interfaces. For example, instead of using a horrible mess of templates to structure content on a page, you could store the underlying data in a structured format such as JSON and then write a MediaWiki extension that builds a custom editing interface on top of this structured data. This approach is used by MassMessage to create delivery list pages and by CollaborationKit for creating WikiProjects. Although these extensions have their own workflows for creating pages, Special:ChangeContentModel can also be used.

As an alternative to setting content models on a page-by-page basis, you can specify alternative defaults for a given namespace. For example, the default namespace in the Module namespace is ScribuntoContent. Similarly, you can enforce that a given content model is only used in a given namespace; ScribuntoContent can only be used in the Module namespace.

Visualizando o modelo de conteúdo atual de uma página
To view a page's current content model, click "" in the sidebar toolbox. You can also append  to a URL to get the same page.

Mudando o modelo de conteúdo de uma página
Go to Special:ChangeContentModel, enter the page name you wish to change. This can be a non-existent page if you wish to create a new page that uses a different content model from the default. Next, choose the content model you wish to change to. Click "" to make the change.

Note that not all conversions are possible. If you are trying to convert a page that already exists and the MediaWiki software cannot figure out how to re-interpret the current page's content, the content model will not be converted and you will get an error message. When this happens, it is recommended that you archive the old page and create the page anew in the new content model. For instance, you could rename "Project:Foo" to "Project:Foo/old" and then use Special:ChangeContentModel to create a new page at "Project:Foo". If possible, you should include a link to "Project:Foo/old" on the new page.

Desfazendo uma mudança
All content model changes are logged at Special:Log/contentmodel on your wiki. To undo a change, go to the relevant entry in the log and click "". You will see a pre-filled form; click "" to carry out the revert.

Note that this may not always work, particularly if the page was edited after the content model was changed in such a way to make it incompatible with the old content model. When this happens, you will have to undo the edits that made it incompatible. Alternatively, you could carry out the content model change anew and archive the old content. Ideally, content model changes are few and far between. In most situations, a page will not have to change content model more than once.
