Ruby on rails : using update inside show for REST API -


while accessing rest api on rails encountered inside rails console can happen

variable = model.find(1) //random id variable.update(:column => variable.column + 1) //my column numeric

but this, while possible on console cannot find translation ruby api exact method

any ideas?

instance = model.find(params[:id]) instance.increment!(:attribute_to_increment, = 1)

note :attribute_to_increment has numeric.
