Passing strings from model to a form, to edit the information

Yeah,

I’m trying to develop a “User Profile” and want to show some forms with the content stored in database. I search in documentation but i don’t find anything useful. I try

at controller: @u = User.find(:last)

at view:

<% form_for :user |f| do %> f.text_field :name, :object => @u.name <% end %>

But what’s object really does?

Don't know, what you're doing here. You should use: @user = User.find(:last)

Then: <% form_for :user |f| do %> f.text_field :name <% end %>

Is all you need. If you use form_for :user, then Rails expects the data to be in object @user and if you use f.text_field instead of the simple text_field, then Rails knows already, that the object to be used is that bound to the form (@user in htis case) and knows, that :name is @user.name
