Recline Views
|

</h1>
|
||||
</div>
|
||||
|
||||
Recline Views are instances of Backbone Views and they act as 'WUI' (web user
|
||||
interface) component displaying some model object in the DOM. Like all Backbone
|
||||
views they have a pointer to a model (or a collection) and have an associated
|
||||
DOM-style element (usually this element will be bound into the page at some
|
||||
point).
|
||||
|
||||
Views provided by core Recline are crudely divided into two types:
|
||||
|
||||
* Dataset Views: a View intended for displaying a recline.Model.Dataset in some
|
||||
fashion. Examples are the Grid, Graph and Map views.
|
||||
* Widget Views: a widget used for displaying some specific (and smaller) aspect
|
||||
of a dataset or the application. Examples are QueryEditor and FilterEditor
|
||||
which both provide a way for editing (a part of) a `recline.Model.Query`
|
||||
associated to a Dataset.
|
||||
|
||||
## Dataset View
|
||||
|
||||
These views are just Backbone views with a few additional conventions:
|
||||
|
||||
1. The model passed to the View should always be a recline.Model.Dataset
|
||||
instance
|
||||
2. Views should generate their own root element rather than having it passed
|
||||
in.
|
||||
3. Views should apply a css class named 'recline-{view-name-lower-cased} to the
|
||||
root element (and for all CSS for this view to be qualified using this CSS
|
||||
class)
|
||||
4. Read-only mode: CSS for this view should respect/utilize a parent
|
||||
recline-read-only class in order to trigger read-only behaviour (this class
|
||||
will usually be set on some parent element of the view's root element).
|
||||
5. State: state (configuration) information for the view should be stored on an
|
||||
attribute named state that is an instance of a Backbone Model (or, more
|
||||
speficially, be an instance of `recline.Model.ObjectState`). In addition, a
|
||||
state attribute may be specified in the Hash passed to a View on
|
||||
iniitialization and this information should be used to set the initial state
|
||||
of the view.
|
||||
|
||||
Example of state would be the set of fields being plotted in a graph view.
|
||||
|
||||
More information about State can be found below.
|
||||
|
||||
To summarize some of this, the initialize function for a Dataset View should
|
||||
look like:
|
||||
|
||||
<pre>
|
||||
initialize: {
|
||||
model: {a recline.Model.Dataset instance}
|
||||
// el: {do not specify - instead view should create}
|
||||
state: {(optional) Object / Hash specifying initial state}
|
||||
...
|
||||
}
|
||||
</pre>
|
||||
|
||||
Note: Dataset Views in core Recline have a common layout on disk as follows,
|
||||
where ViewName is the named of View class:
|
||||
|
||||
<pre>
|
||||
src/view-{lower-case-ViewName}.js
|
||||
css/{lower-case-ViewName}.css
|
||||
test/view-{lower-case-ViewName}.js
|
||||
</pre>
|
||||
|
||||
### State
|
||||
|
||||
State information exists in order to support state serialization into the url
|
||||
or elsewhere and reloading of application from a stored state.
|
||||
|
||||
State is available not only for individual views (as described above) but for
|
||||
the dataset (e.g. the current query). For an example of pulling together state
|
||||
from across multiple components see `recline.View.DataExplorer`.
|
||||
|
||||
### Flash Messages / Notifications
|
||||
|
||||
To send 'flash messages' or notifications the convention is that views should
|
||||
fire an event named `recline:flash` with a payload that is a flash object with
|
||||
the following attributes (all optional):
|
||||
|
||||
* message: message to show.
|
||||
* category: warning (default), success, error
|
||||
* persist: if true alert is persistent, o/w hidden after 3s (default=false)
|
||||
* loader: if true show a loading message
|
||||
|
||||
Objects or views wishing to bind to flash messages may then subscribe to these
|
||||
events and take some action such as displaying them to the user. For an example
|
||||
of such behaviour see the DataExplorer view.
|
||||
|
||||
### Writing your own Views
