-------------------------------------
Summary: HTML and XDOC generation -schema tabl fields inherits
attribute value if not set
Key: TORQUE-358
URL: https://issues.apache.org/jira/browse/TORQUE-358
Project: Torque
Issue Type: Bug
Components: Templates
Affects Versions: 4.1
Reporter: Georg Kallidis
Fix For: 4.1
Changing the example schema (src/test/schema.xml) adding a field e.g
{code:java}
<column
name="contactdata"
required="true"
type="VARCHAR"
size="500"
/>
{code}
in table "a" _after_ field "name" having a default value ("a_name") the HTML
and XDOC the default value from the preceding field is set for filed
"contactdata". This happens only if it is a column with another column of the
same type before. As a consequence the JUNit - Test TestProcessing fails
(test*docTemplate) - SQL generation is not affected.
Another example of a schema.xml change. Result is that CURRENT_TIMESTAMP is in
HTML/XDOC output for *both* fields (created_at, updated_at), while SQL and Java
generation is done correctly.
{code:java}
<column
name="created_at"
required="true"
type="TIMESTAMP"
default="CURRENT_TIMESTAMP"
scale="6"
/>
<column
name="updated_at"
required="true"
type="TIMESTAMP"
scale="6"
/>
{code}
Fixing seems to me not easy as far as I can see - some complex velocity
inheritance mechanism (velocity 1.7) is used, the fields seems to inherit from
other fields in the same table.
Workaround may be done by overriding explicitely the attribute resetting it in
schema.xml.
But I think this feature is neither at the core of Torque nor it is documented
(I did not know about it before).
[https://db.apache.org/torque/torque-4.0/index.html] states quite lakonikely:
_torque-templatesThe Torque Templates contain the building blocks used by the
generator to create the O/R classes, SQL scripts *and the like*. You can extend
or change the templates if you want to customize the output of the generator,
or even write templates of your own._
Generation of SQL and OM classes is not concerned (apparently uses different
code). What about, just skipping this (almost unknown) feature (HTML and XDOC
generation), until it is fixed/reimplemented in an upcoming release?
