|
||||
|
||||
<p>A. provide metadata as model data to the Dataset</p>
|
||||
<p>This is very artificial and is really only designed for testing
|
||||
purposes.</p>
|
||||
|
||||
<p>B. Set backendConfig on your dataset with attributes:</p>
|
||||
<p>To use it you should provide in your constructor data:</p>
|
||||
|
||||
<ul>
|
||||
<li>type: 'memory'</li>
|
||||
<li><p>data: hash with 2 keys:</p>
|
||||
<li>metadata (including headers array)</li>
|
||||
<li><p>documents: list of hashes, each hash being one doc. A doc <em>must</em> have an id attribute which is unique.</p>
|
||||
|
||||
<ul><li>headers: list of header names/labels</li>
|
||||
<li>rows: list of hashes, each hash being one row. A row <em>must</em> have an id attribute which is unique.</li></ul>
|
