XML Template - Advanced case
The main approach based on elements with "cj:" namespace covers 99% of all actual cases. If you have a case that belongs to the remaining 1% and need extra functionality then consider using Thymeleaf template engine. It is a part of the platform that Codejig system is running on. So it is enabled right away and does need any additional configuration.
Here are two examples, just to show a difference.
Example 1
Codejig style implementation:
<a cj:if="object.f47.f77">
The parent tag will be added to the result only if object.f47.f77 is not null.
</a>
Thymeleaf implementation:
<a th:if="${object.getField47().getField77()}">
The parent tag will be added to the result only if object.f47.f77 is not null.
</a>
Example 2
Codejig style implementation:
<a cj:with="my_var = object.f47.f77">
<b>The value is {my_var.f477}</b>
<b>The value is {my_var.f4478:V1234}</b>
</a>
Thymeleaf implementation:
<a th:with="my_var = ${object.getField47().getField77()}">
<b th:text="'The value is' + ${{my_var.getField4477()}}"/>
<b th:text="'The value is' + ${valueFormatter.format(my_var.getField4478(), 1234L)}"/>
</a>
As you may see we use namespace "th:" for Thymeleaf implementation. Also data fields are referred a bit differently. And finally, to format data you may need an additional service object - valueFormatter.
The valueFormatter object provides a number of methods:
| Method signature | Description |
| format(AbstractMetaEntity sourceItem, Long viewId) | Use for applying concrete string view |
| formatField(AbstractMetaEntity sourceItem, Long fieldId) | Use for applying a default string view for the field |
| formatFloat(AbstractMetaEntity sourceItem, Long fieldId, Integer scale) | Use for applying float number format together with "Decimal" primitive types |
| formatFloat(Object value, Integer scale) | Use for applying float number format together with "Double" primitive types |
| formatDecimal(Object value, Integer length, Boolean leadingZeros) | Use for applying integer number format |
| formatBoolean(Object value, Boolean uppercase) | Use for applying boolean value format |
