How do I specify the method of an action (similar to _delete):
generator:
config:
list:
object_actions:
myaction: {label: Label, action: myaction, method: post}
This ignores my method setting and renders a get link:
<a href="/backend/myaction/1">Label</a>
Whereas I want it to a "post" link, similar to _delete (with onclick attribute)
I guess your using Propel.
If you check the generator code, specifically on: generator > theme_name > template > template > _list_td_actions.php, there you'll find a pice of code like:
<?php else: ?>
<li class="sf_admin_action_<?php echo $params['class_suffix'] ?>">
<?php echo $this->addCredentialCondition($this->getLinkToAction($name, $params, true), $params) ?>
</li>
<?php endif; ?>
That's the code thats being executed when you define a custom object action like the one you described. Check $params and you may find a solution to your needs ( i think that probably you could define something like the onclick attribute value).
