<p>A simple MongoDB output node. Stores the <b>msg</b> object in a chosen collection.</p>
|
||||
<p>A simple MongoDB output node. Can save, insert, update and remove objects from a chosen collection.</p>
|
||||
<p>Save will update an existing object or insert a new object if one does not already exist.</p>
|
||||
<p>Insert will insert a new object.</p>
|
||||
<p>Save and insert either store <b>msg</b> or <b>msg.payload</b>.</p>
|
||||
<p>Update will modify an existing object or objects. The query to select objects to update uses <b>msg.query</b> and the update to the element uses <b>msg.payload</b>.</p>
|
||||
<p>Update can add a object if it does not exist or update multiple objects.</p>
|
||||
<p>Remove will remove objects that match the query passed in on <b>msg.payload</b>. A blank query will delete <i>all of the objects</i> in the collection.</p>
|
||||
<p>By default MongoDB creates an <i>_id</i> property as the primary key - so repeated injections of the same <b>msg</b> will result in many database entries.</p>
|
||||
<p>If this is NOT the desired behaviour - ie you want repeated entries to overwrite, then you must set the <b>msg._id</b> property to be a constant by the use of a previous function node.</p>
|
||||
<p>If this is NOT the desired behaviour - ie. you want repeated entries to overwrite, then you must set the <b>msg._id</b> property to be a constant by the use of a previous function node.</p>
|
||||
<p>This could be a unique constant or you could create one based on some other msg property.</p>
|
||||
<p>Currently we do not limit or cap the collection size at all... this may well change.</p>
|
||||
<p>You can also choose to <b>remove</b> items. To do so the <b>msg.payload</b> <i>MUST</i> contain an object that will select the items(s) to remove.
|
||||
A blank object will delete <i>all of the objects</i> in the collection.</p>
