show the new form view I got this error:
ActiveRecord::AssociationTypeMismatch in Audit testsController#new

This is my controller:
class AuditTestsController < ApplicationController
unloadable
before_filter :find_project
def index
@audit_tests = AuditTest.find(:all)
end
def new
@test_statuses = TestStatus.find(:all)
@audit_test = AuditTest.new
@audit_test.project = @project # <------- HERE I got the
error
render :layout => !request.xhr?
end
def create
if @audit_test.save
#attach_files(@issue, params[:attachments])
flash[:notice] = l(:notice_successful_create)
#Mailer.deliver_issue_add(@issue) if
Setting.notified_events.include?(''issue_added'')
redirect_to :action => ''index''
return
end
end
def update
end
def destroy
end
def show
end
private
def find_project
@project = Project.find(params[:project_id])
end
end
And this is the view:
<h2><%=l(:label_audit_test_plural)%></h2>
<% html_title(l(:label_audit_test_plural)) %>
<%= link_to l(:label_audit_test_new), :controller =>
"audit_tests", :action => "new", :project_id =>
@project %>
<% if @audit_tests.empty? %>
<p class="nodata"><%= l(:label_no_data) %></p>
<% else %>
<%= render :partial => ''audit_tests/list'', :locals =>
{:audit_tests =>
@audit_tests, :query => @query} %>
<% end %>
Project is something I not manage, is part of the main application, so
I don''t know if it changes at runtime.
