Question:
I am trying to show concatenated information in the drop downs text.
This is what I have:
<%=collection_select(:product, 'prod_name', @prods, :id, "#{:category.name - :prod_name}", {:prompt => 'Select Product'})%>
Product belongs_to category.
So i can do the following which works fine:
@p = Product.all @p.first.prod_name @p.first.category.name
So eventually i want a drop down that has categoryname - product name
For example: if category name is Edible and product name is Brownie then in drop down i want Edible - Brownie
Solution:1
There's a couple of different ways of doing it, but I would define a new instance method on the product model like:
def category_product_name "#{self.category.name} - #{self.prod_name}" end
Then you can use this in your view:
<%=collection_select(:product, 'prod_name', @prods, :id, :category_product_name, {:prompt => 'Select Product'})%>
