Hello, So basically I have a case of multiple objects in one form. I have implemented sort of bulk_update_or_delete method that updates all the fields for all of the objects and which is working fine at the moment. However, I''m still a bit lost with the whole process when it comes to additional parameters such as _delete. I currently use the <%= f.check_box :_delete %> However the handler in the model (bulk_update_or_delete) looks like this def self.bulk_update_or_delete(attributes) for a in attributes do unless a[1][''_delete''] == ''1'' u = User.find_by_id(a[0].to_i) a[1].delete(''_delete'') u.attributes = a[1] u.save(false) else u = User.find_by_id(a[0].to_i) u.destroy end end end Which definitely looks a lot like a hack. Compared to some of the examples I found, I had to manually remove the _delete attribute from the list or I got an error when calling u.attributes = a[1] While this semi-hack works nicely, my problem arises when my form has a checkbox next to a password. The idea of my UI solution is that the password for this user will only be set if and only if this checkbox is checked. My initial solution would be to add an attribute for the object in the form along the lines of ''change_password'' and should it be checked, remove the password attribute from the list of submitted attributes along with the change_password attribute itself. I can think of doing this in the controller before submitting it to the bulk_update_or_delete but I''d rather do it there (it resides in the user model). Basically I''m looking for an alternative, neater, solution for both the original manual removal of these attributes as well as implementing the additional checkbox. Any advice? -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
