newbie, reciving a hash from the view

rubyonrails-talk
1

hi, i am new in ruby, i have to do the next

Send a hash (key are strings and values are booleans) to the view, show it like check box in the view, using string like nome and the value like check or not checked, and recover this hash modified to the controller for work with it so i wrote this

in the view

<%@arquitectures.each do |key, value| %> <%=key.to_s%> <%=check_box(key, value, {}, true, false) %> <%end%></p>

in the controller

before_filter loadArchitectures #here load @architectures def create    if request.post?       begin         @architectures.each do |key, value|             if value               newArchitecture=Architecture.new()               newArchitecture.nombre=clave               newArchitecture.project_id=@project.id               newArchitecture.save

            end           end

But when i see the values of @architectures after request.post? they are the originals values. Some help please (and sorry for my english)

It doesn't look like you are changing the objects in @architectures at all (or indeed using the values at all (apart from controlling how many new architectures you create) Also you appear to be misusing check_box slightly - the intent is that the first argument is the name of an instance variable and the second the name of a boolean attribute.

i use the hash @architectures, just for create news Architectures, because the names of the architectures can change dinamically, so with the hash i collect the possibles names and, in the view, if the user check it, i create the new architecture, or if the user unchecked i delete it (but this part is not show in the post)

could you suggest me some code please? Thanks a lot
