A NOT NULL constraint is essential tool in postgres database to ensure validation.
But sometimes, you need to remove not null and allow column to be null.
ALTER TABLE table_name ALTER COLUMN column_name DROP NOT NULL
You can remove the file from the local cache first and push that
git rm --cached /file/to/be/removed/from/cache
Then do the status to see the delete has taken place
git status
You will see something like
deleted: /file/to/be/removed/from/cache
Then push the change
git push
Zend will ship its elements with tags of dd dt
But if you want to get only the element with out decorator being around it.
you can do:
$this->addElement('text', 'you_element', array(
....
'decorators' => array('viewHelper'),
....
));
But if you want to display errors along with the HTML format,
add errors in the decorators array
This should give you only the element that you can implement your own decorator around it
