你需要迭代一个像:
这样的数组a = (1..10).to_a #or however many ID's you want.
a.each do {|d| user.projects.create!(:title => Faker::Lorem.sentence(1), :project_pages_id => d)}
我确信还有其他方法,但这很快,很脏,而且只是一个测试。

project_pages_id是否是外键?如果是这样,为什么你会自动递增它以使它具有nil关联?
看起来你正在尝试创建种子数据。一个好方法是使用Factory Girl:

除此之外,它还有“序列”的概念,它解决了你原来的问题:
# Defines a new sequence
Factory.sequence :email do |n|
"person#{n}@example.com"
end
Factory.next :email
# => "person1@example.com"
Factory.next :email
# => "person2@example.com"
