I'm using grid to display a list of users. I have the user's name represented as a link with the user_id encoded. I want to impersonate the user when I click on the link. I haven't been able to figure out how to do that. So far, the best I can do is get to the impersonate form and enter the user's ID. Without resorting to an ajax form submission, is there a way to click the link and do a POST to impersonate to get it to accept a user's ID as an argument? I suppose I could represent every username as a form, but this seems cumbersome. I suspect there's an easier way.
