RubyOnRails | ActiveRecord::AssociationTypeMismatch

I have a Stage Model, which belongs_to User Model. User Model has_many Stages.

When I try to create a New Stage, with an hidden_field containing the id of current_user , I have the following error :

ActiveRecord::AssociationTypeMismatch in StagesController#create
User(#63609336) expected, got String(#16545012)

Here's the array :

 {"utf8"=>"✓",
 "authenticity_token"=>"YD3VVr9Hntg/LEGjFAzu2roR5NGe6FPclew+zJOvGpY=",
 "stage"=>{"user"=>"8",
 "intitule"=>"er",
 "entreprise"=>"er",
 "secteur"=>"er",
 "mission"=>"er",
 "duree"=>"erea",
 "annee_debut"=>"az",
 "annee_fin"=>"z",
 "comment"=>"az",
 "site_entreprise"=>"az"},
 "commit"=>"Create Stage"}

user_id is an Integer field.

The view :

<%= f.hidden_field :user, :value => current_user.id %>

Where is the problem ? I can't find any solution ! Thanks for your help.

I wouldn't recommend using hidden fields for this, as hidden fields can be modified by the user. I recommend doing something like current_user.stages.create in the controller instead, which will pre-populate the user_id in the created Stage.

replace with 

<%= f.hidden_field :user_id, :value => current_user.id %>
