I am on 73 and have a question about saving this form.</p> <p>I have pasted some code and while following <a href="http://media.railscasts.com/videos/073_complex_forms_part_1.mov" rel="nofollow">railscasts 73</a>. My code is a bit different at around line 20 to 23 regarding another post relationship. Using debugger, @post only has the user_id and the post values. params contains the lineitem_attributes. The lineitems do not get saved.</p> <p>How do I build the post including the lineitems?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
