zend-framework - How do I ignore the created column on a Zend_DB table save?

Question

how would I ignore having Zend_DB save() from trying to fill out a created column? I do not need that column for a certain model.

Answer 1

Don't send the data. save() is part of the Zend_Db_Table_Row api and is designed to be somewhat intelligent in the way it saves data to a row. It will perform an insert or an update of a row depending on what is required.

save() will also only update the columns that it has data for. If you don't send new data for your created column save() won't overwrite the data.

When ever it is possible I let the database I'm using create and update the columns for created and updated. That way I have the information available to query if I need it but I don't have to do something with PHP that My database can do better.

Answer 2

Check out http://framework.zend.com/manual/1.12/en/zend.db.table.html Section "Advanced usage".

For more specific and optimized requests, you may wish to limit the number of columns returned in a row or rowset. This can be achieved by passing a FROM clause to the select object. The first argument in the FROM clause is identical to that of a Zend_Db_Select object with the addition of being able to pass an instance of Zend_Db_Table_Abstract and have it automatically determine the table name.

Important

The rowset contains rows that are still 'valid' - they simply contain a subset of the columns of a table. If a save() method is called on a partial row then only the fields available will be modified.

So, if you called an update() I think it would be as simple as unsetting the value for the column you don't want to touch. Of course database constraints will need to be honored - i.e. column should allow nulls.
