Say I had many inputs with ids and names in this format: object\_#,  
where # is any number. Each input is inside its own form with its own  
submit button. How can I make the controller get the @params[object\_#]?

Assuming the # is in a local variable named my\_object

@params[“object\_#{my\_object}”]

Or, if it is a symbol, then perhaps

@params[“object\_#{my\_object}”.to\_sym]

Something like that should do it.

Well, this test code works, so it’s just a tweak needed for your  
exact names & data types and such.

params = Hash.new

params.store(‘object\_1’,‘One’)  
params.store(‘object\_2’,‘Two’)  
params.store(‘object\_3’,‘Three’)

my\_object = ‘2’

p params[“object\_#{my\_object}”]

– or with symbols –

params = Hash.new

params.store(:object\_1,‘One’)  
params.store(:object\_2,‘Two’)  
params.store(:object\_3,‘Three’)

my\_object = ‘2’

p params[“object\_#{my\_object}”.to\_sym]
