I have following view for user input:

# Post new thing
\<%= form\_tag :action =\> 'create' %\>

Title  
\<%= text\_field 'thing', 'title' %\>

Description  
\<%= text\_area 'thing', 'description' %\>

Email  
\<%= text\_field 'thing', 'email' %\>

\<%= submit\_tag "Create" %\> \<%= form\_tag %\>

… and following controller that populates data (one row) in database

def create  
@thing = Thing.new(params[:thing])  
end

So far it is working. But I need to add one more parameter to @thing  
variable that doesn`t come from user input. It comes from another model  
(:another\_main\_thing\_id). What is the syntax for adding this parameter  
to @thing variable.  
Thank you!

There’s an accessor function created for you for each database  
attribute
