All Implemented Interfaces:

NSKeyValueCoding, NSKeyValueCoding.ErrorHandling, NSKeyValueCodingAdditions, NSValidation

public abstract class ERD2WDirectAction

extends ERXDirectAction

Cool class to automatically create page configurations from URLs.
Examples: QueryArticle will create an query page for articles. QueryArticle?__fs=findNewArticles will create an query page for fetch spec "findNewArticles". This will only work if your rules return a ERD2WQueryPageWithFetchSpecification. InspectArticle?__key= will create an inpect page for the given article. EditArticle?__key= will create an edit page for the given article. CreateArticle will create an edit page for a newly created article. ListArticle?__key=&__keypath=User.articles will list the articles of the given user. ListArticle?__fs=recentArticles&authorName=*foo* will list the articles by calling the fetch spec "recentArticles". When the fetch spec has an "authorName" binding, it is set to "*foo*".

fetchSpecificationFromRequest

public EOFetchSpecification fetchSpecificationFromRequest(String entityName)

Retrieves and executes the fetch specification given in the request.

primaryKeyFromRequest

public Number primaryKeyFromRequest()

Deprecated. use primaryKeyFromRequest(EOEditingContext ec, String entityName)

primaryKeyFromRequest

public NSDictionary primaryKeyFromRequest(EOEditingContext ec,
                                          String entityName)

reportException

public WOActionResults reportException(Exception ex)

performActionNamed

public WOActionResults performActionNamed(String anActionName)

Overrides the default implementation to try to look up the action as a page configuration if there is no method with the wanted name. This implementation catches NoSuchMethodException more or less silently, so be sure to turn on logging.

Overrides:
