[TYPO3-dev] Fields in the TCA that does not exist in the DB

[Malte Jansen]

Perhaps there should be a check for the DB if the field exists. If the 
field does not exists, there should be an warning/error-message-box like 
the "ENABLE_INSTALL_TOOL" on the module-page. Perhaps this box code be 
used for messages from hooks too, which have some special checks.
But the box would be another feature. You could use is for 
db-error-messages and the dataset is open again, so you could check the 
field-value again. You could have have 2 levels: warning (yellow), error 
(red).

But back to the topic.
The default value should be false. Because it the standard for all 
existing extensions. So you know if the db-field is wanted. You could 
use $TYPO3_DB->admin_get_fields(tablename) for checking (perhaps in the 
EM instead of "some fields are missing") it, but sometimes you update 
modify a extension and you forget to add the field to sql-field. So you 
don't know I it is a real noDB field. So there should be a parameter, 
because developing new extension would be much easier...

Short:
So "noDB = true" wouldn't make request to the db and would unset the 
value before saving.
If you would check every field with 
$TYPO3_DB->admin_get_fields(tablename) wheather it exists or not, it 
costs much more time (and resources?).
