我想我打破了我的项目。 :(我做了很多改变，其中之一是改变我的资源，所以它们嵌套（浅：真）。我试图种子我的数据库再次，我得到一个TypeError：没有隐式转换符号到整数消息。我已经通过计算器望去，一个人也有类似的问题，但没有答案，我还没有发现，在互联网上工作的其他地方的答案嵌套数据库与嵌套资源：没有将符号隐式转换为整数
我的路线文件：
Goalie::Application.routes.draw do
resources :users, shallow: true do
resources :goals
resources :steps
resources :habits
end
我的长相模式。像这样：
ActiveRecord::Schema.define(:version => 20161121101351) do
create_table "users", :force => true do |t|
t.integer "user_id"
t.string "firstname"
t.string "lastname"
t.string "username"
t.string "password"
t.string "userEmail"
t.datetime "created_at", :null => false
t.datetime "updated_at", :null => false
end
create_table "goals", :force => true do |t|
t.integer "goal_id"
t.string "name"
t.string "description"
t.date "deadline"
t.boolean "completed"
t.datetime "created_at", :null => false
t.datetime "updated_at", :null => false
end
create_table "steps", :force => true do |t|
t.integer "step_id"
t.string "name"
t.string "description"
t.boolean "completed"
t.datetime "created_at", :null => false
t.datetime "updated_at", :null => false
end
create_table "habits", :force => true do |t|
t.integer "habit_id"
t.string "name"
t.string "description"
t.boolean "frequency"
t.integer "frequencytime"
t.datetime "created_at", :null => false
t.datetime "updated_at", :null => false
end
end
而seed.rb文件如下所示：
params = { :user =>
{
:user_id => '1',
:firstname => 'Salaman',
:lastname=> 'Rushdie',
:username=> 'bigboss',
:password=> 'admin',
:userEmail=> '[email protected]',
:goals_attributes => {
:goal_id => '1',
:name => 'Lose weight',
:description => 'Lose 30lb',
:deadline => '25/12/2016',
:completed => false,
:steps_attributes => {
:step_id => '1',
:name => 'Work out',
:description => 'Exercise to achieve weight loss goal',
:completed => false,
:habits_attributes => {
:habit_id => '1',
:name => 'Gym',
:description => 'Go to the gym 5 times a week',
:frequency => 'true',
:frequencytime => '5',
}
}
}
}
}
User.create!(params[:user])
，当我尝试种子数据库，我得到这个消息：
$ rake db:seed --trace
** Invoke db:seed (first_time)

让我知道是否有任何可能需要的其他信息。我会继续拉我的头发，盯着代码。 :)
