Detailed Description

The EditorialModel is a read-only model used to fetch editorials related to a Place. Binding a Place via EditorialModel::place initiates an initial fetch of editorials. The model performs fetches incrementally and is intended to be used in conjunction with a View such as a ListView. When the View reaches the last of the editorials currently in the model, a fetch is performed to retrieve more if they are available. The View is automatically updated as the editorials are received. The number of editorials which are fetched at a time is specified by the batchSize property. The total number of editorials available can be accessed via the totalCount property.

The model returns data for the following roles:

RoleTypeDescription
textstringThe editorial's textual description of the place. It can be either rich (HTML based) text or plain text depending upon the provider.
titlestringThe title of the editorial.
languagestringThe language that the editorial is written in.
supplierSupplierThe supplier of the editorial.
userUserThe user who contributed the editorial.
attributionstringAttribution text which must be displayed when displaying the editorial.
