Question

I have a hash in Ruby:

params={"username"=>"test"}

I want to add another associative array like:

params["user"]={"name"=>"test2"}

so params should become

params={"username"=>"test","user"=>{"name"=>"test2"}}

but when I post this params to a url, I get:

params[:user][:name] # => nil

when I dump the user data:

 params[:user] # => ['name','test2']

what I want is

 params[:user] # => output {'name'=>'test2'}

what am I doing wrong? thanks for help.

You’re just using wrong key, you think that :user and "user" are the same, which is not.

params["user"]["name"] #=> "test2"
params["user"]         #=> {"name"=>"test2"}

UPDATE from Naveed:

:user is an instance of Symbol class while “user” is instance of String
