Hi everybody,

Here’s the story… I’m making an application that’s gonna help me  
manage my money when i go to the grocery store…nothing  
complicated… Here’s how i did the first coding:

script/generate scaffold Food name:string description:text type:string  
recurrence:string price:integer …

rake db:migrate

here is some excerpts of my controller and view respectively:

foods\_controller.rb

# GET /foods/new

# GET /foods/new.xml

def new  
@food = Food.new  
@type = [“Fruits & Vegetables”, “Grain Products”, “Meat &  
Alternatives”, “Milk Products”, “Beverages”, “Other”]  
@recurrence = [“Weekly”, “Biweekly”, “Monthly”]

```
respond_to do |format|
  format.html # new.html.erb
  format.xml { render :xml => @food }
end

```

end

new.html.erb

\<%= f.label :description %\>  
 \<%= f.text\_area :description %\>

\<%= f.label :type %\>  
 \<%= f.select :type, @type.collect { |t| [t, t] } %\>

\<%= f.label :recurrence %\>  
 \<%= f.select :recurrence, @recurrence.collect { |r| [r, r] } %\>

Everything looks OK… but when create a new Food, lets say a Tomato,  
everything is OK except for the “type” column in my db… if i go to  
the view it shows everything except “type” which is empty…

I don’t know what is wrong with the word “type”, cause i’ve tried the  
same application several times with different names (instead of  
“type”, i named my column “category”) and it worked… the only time  
it doesnt work is when the column name is “type”…

Why is that ???

Thank you guys for your help !

the type column is used for single table inheritance.
