Hi all,
I'm ashamed to ask this but I can't figure it out. Lately my brain gets more burned out by the minute. Basically I'm trying to have a shirt have up to 2 colors. I currently have this working. When I edit a shirt, I can select the primary and secondary color of a shirt. But when I want to see the colors in the show page I can't manage to see the name only the id.
For example:
<b>Primary Color:</b> <%=h @shirt.color_id %><br />
<%=h @shirt.primary_color_name %>
<b>Secondary Color:</b> <%=h @shirt.color2_id %><br />
<%=h @shirt.secondary_color_name %>
Only displays the id (obviously) but what I want to see is the NAME OF THE COLOR. I just can't think of a way to do this for some reason. Maybe there is a better way to do this and you guys can shed a light?
Below is the database structure and model relationship code...
APPROVED_COLORS (table name/structure in db) ------- :id (int) :name (string)
SHIRTS (table name/structure in db) ------- :color_id (int) :color2_id (int)
APPROVED_COLOR.RB -------- belongs_to :shirt
SHIRT.RB ---------- has_many :approved_colors
has_one :primary_color, :class_name => 'ApprovedColor', :foreign_key => :color_id has_one :secondary_color, :class_name => 'ApprovedColor', :foreign_key => :color2_id
Any help on this is greatly appreciated.
Thanks, Tony --
class Shirt def primary_color_name self.primary_color ? self.primary_color.name : '(none)' end def secondary_color_name self.secondary_color ? self.secondary_color.name : '(none)' end end
If this doesn't quite work as-is, please take it as a strong hint and an exercise in using the documentation of has_one
