Rails - Apr 2008 - Howto pass hashes in params?

Hello,

i try to pass a hash in params.

h = Hash.new

[...]

<%= link_to ''next'',:url => {:controller =>
''myController'', :action =>
''myAction'', :h => h} %>


The myController-controller:

  def myController
    @h = params[:h]
  end

But it doesn''t work like this. Can someone give me a solution. Is it
even possible to pass hashes in params?

regards

Try this:

In a Controller:

  params[:myhash] => { :aa => ''hashaa'', :bb =>
''hashbb'' }

OR

In a view:

<% @myhash = { :aa => ''hashaa'', :bb =>
''hashbb'' } -%>
<%= link_to ''next'',
  :controller => ''myController'',
  :action => ''myAction'',
  :mykey => @myhash %>

Gives

--- !map:HashWithIndifferentAccess
action: new
controller: entities
mykey: !map:HashWithIndifferentAccess
  aa: hashaa
  bb: hashbb

That should be:

   params[:myhash] = { :aa => ''hashaa'', :bb =>
''hashbb'' }
