Howto pass hashes in params?

Rails
1

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’ }
