They’re different classes of thing.

The relationship between forms and fields on web pages is very similar  
to that of tables and fields in databases.

they are both to do with binding an object to an instance of form  
builder, but form\_for also outputs the tags. If you thing of  
form\_for being

“\<form #{various form level options}” + fields\_for(…) + then  
you’re not far off.
