dataView :string

The view name that contains the list of fields to use when fetching the model/collection from the server.

fallbackFieldTemplate :string

A template to use for view fields if a field does not have a template defined for its parent view. Defaults to "default".

For example, if you have a subview and don't want to define subview template for all field types, you may choose to use existing templates like detail if your subview is in fact a detail view.

Methods


<static> _hide()


<static> _show()


<static> closestComponent()


<protected> _dispose()

Disposes a view.

This method disposes view fields and calls the View/Component#_dispose method of the base class.

Overrides:

<protected> _disposeFields()

Disposes all the fields.


<protected> _hide()

Override this method to provide custom show logic.

Inherited From:

<protected> _render()

Renders a view onto the page.

The method first renders this view by calling View/View#_renderHtml and then for each field invokes View/View#_renderField.

NOTE: Do not override this method, otherwise you will lose ACL check. Consider overriding View/View#_renderHtml instead.

Overrides:
Returns:

The instance of this view.

Type
View/View

<protected> _renderField(field, $fieldEl)

Sets field's view element and invokes render on the given field.

Parameters:
Name Type Description
field View/Field

The field to render.

$fieldEl jQuery

The field placeholder.


<protected> _renderFields()

Renders all the fields.


<protected> _renderHtml( [ctx] [, options])

Renders a view onto the page.

This method uses ctx parameter as the context for the view's Handlebars View/View#template and view's options.templateOptions property as template options.

If no ctx parameter is specified, this is passed as the context for the template. If no options parameter is specified, this.options.templateOptions is used.

You can override this method if you have custom rendering logic and don't use Handlebars templating or if you need to pass a different context object for the template.

Note the following use of ViewManager.View.extend is deprecated in favor of putting these controllers in the sugarcrm/clients/ directory. Using that idiom, the metadata manager will declare these components and take care of namespacing by platform for you (so MyCustomView will be stored internally as MyappMyCustomView). If you do choose to use the following idiom please be forewarned that you will lose any namespacing benefits and possibly encounter naming collisions!

Example:

// Note that using the following technique of defining custom views
// directly on the ViewManager.views object can result in naming
// collisions unless you ensure your name is unique. See note above.
ViewManager.views.CustomView = ViewManager.View.extend({
   _renderHtml: function() {
      var ctx = {
        // Your custom context for this view template
      };
      ViewManager.View.prototype._renderHtml.call(this, ctx);
   }
});

// Or totally different logic that doesn't use this.template
ViewManager.views.AnotherCustomView = ViewManager.View.extend({
   _renderHtml: function() {
      // Never do this :)
      return "<div>Hello, world!</div>";
   }
});

This method uses this view's View/View#template property to render itself.

Parameters:
Name Type Argument Description
ctx Core/Context <optional>

Template context.

options Object <optional>

Template options.

{
   helpers: helpers,
   partials: partials,
   data: data
}
// See Handlebars.js documentation for details.

<protected> _show()

Override this method to provide custom show logic.

Inherited From:

<protected> _super(method [, args])

Retrieves and invokes parent prototype functions.

Requires a method parameter to function. The method called should be named the same as the function being called from.

Examples:

  • Good:
({
    initialize: function(options) {
        // extend the base meta with some custom meta
        options.meta = _.extend({}, myMeta, options.meta || {});
        // Only call parent initialize from initialize
        this._super('initialize', [options]);
        this.buildFoo(options);
    }
});
  • Bad:
({
    initialize: function(options) {
        // extend the base meta with some custom meta
        options.meta = _.extend({}, myMeta, options.meta || {});
        // Calling a function like buildFoo from initialize is incorrect. Should call directly on this
        this._super('buildFoo',[options]);
    }
});
Parameters:
Name Type Argument Description
method string

The name of the method to call (e.g. initialize, _renderHtml).

args Array <optional>

Arguments to pass to the parent method.

Inherited From:
Returns:

The result of invoking the parent method.

Type
*

<protected> _wrapInitialize(options)

Wraps the initialize method to delegate the events on the element, after it initializes.

Parameters:
Name Type Description
options Object

The Backbone.View initialization options.

Inherited From:

before(name, callback [, context])

Adds a callback/hook to be fired before an action is taken. If that callback returns false, the action should not be taken.

The following example binds a callback function and passes the scope from the view component to use in that callback:

model.before('save', this.doSomethingBeforeSave, this);

Multiple space-separated event names can be bound to a single callback:

view.before('save dispose', this.callback, this);

This method also supports an event map syntax, as an alternative to positional arguments:

this.before({
    render: this.doSomethingBeforeRender,
    dispose: this.doSomethingBeforeDispose,
});
Parameters:
Name Type Argument Description
name string | Object

Event(s) to trigger before. Accepts multiple space-separated event names or an event map.

callback function

Function to be called.

context Object <optional>

Value to be assigned to this when the callback is fired.
