v1.2.2 - Official User Guide


In a MVC architecture, a field is part of a single content type and is used to store an attribute on the Record class. For humans, field nodes are located inside Fieldsets and are used to describe a single field of a content type.

Eg: if your content type is named Products, you will likely have fields for its SKU, Name, Color, etc...

Below you can see the definition of a simple input field:

title :
    column      : true
    description : Title
    type        : text
    rules       : required

or, if you’re using XML schemes:

<field id="title" column="false">
    <description>The title</description>

Let’s talk about it: first of all, a field must have a unique id that will be used as key to store the value.

Second, you will see the column attribute: this boolean describes if this attribute needs to be saved into a physical or logical column. Choose true if the table of your content type (the default is records) contains a column named as the id attribute. Otherwise, the value will be stored in the xml column, serialized with some other fields into an XML. If you are planning to do many intense query operations on this field, using a physical column will greatly improves your performances.

Note: you don’t have to add/remove the physical columns by hand: after changing a scheme, go on the Content types page of the administration and click Rebuild tables on the content type. Bancha will automatically alter the tables for you.

The <type> node describes what kind of field, this field will be. The other fields are optional, and you can easily see the meanings reading them.
