    1. COMy only red flag would be this code `@image = @album.images(params[:id])` aren't you supposed to do `@image = @album.images.where(id: params[:id])`?

    3. COIt references the image correctly how it is... it just produces an arguments error when used in the form

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.
