Question

I am receiving an API call at my server with parameters

first_name , :last_name , :age

etc

I want to bind those params to my object against which user is having attribute with same name , like i want to have these in user[first_name] , user[:last_name]

so that I can just put the complete user object into database in following way ,

User.new(params[:user]) or User.new(some_hash)

I dont want to use the following ,

User.new(:first_name=>params[:first_name],:last_name=>params[:last_name]) 

thanks in advance for you help 🙂

Something like this may work:

user = User.new
params.each do |key,value|
  user[key] = value if user.attribute_names.include?(key.to_s)
end

Note, however, that you should protect sensitive attributes of your User model with attr_protected or attr_accessible in this case.
