Ruby on rails 为什么ActiveRecord:：StatementInvalid:SQLite3:：SQLException:near"；）&引用；：语法错误：插入到"；用户“友谊”；（）值（）

为什么ActiveRecord:：StatementInvalid:SQLite3:：SQLException:near“）”：语法错误：插入到“用户\u友谊”（）值中

尝试测试时：

$ruby-I test/unit/user\u friendships\u test.rb

require 'test_helper'

class UserFriendshipsTest < ActiveSupport::TestCase
should belong_to (:user)
should belong_to (:friend)

test "that creating a frinedship works without raising an exception" do

    assert_nothing_raised do
        UserFriendship.create user: users(:a), friend: friends(:b)
    end

end

end

我也遇到了这个。这似乎与破坏rails命名惯例有关。在我的例子中，用“rails g model activity_item”代替“rails g model activity_items”解决了这个问题。

该表中是否有列？能否发布UserFriendly的代码以及数据库模式？是的，该表中有列。我刚刚用部分模式更新了帖子

create_table "user_friendships", :force => true do |t|
 t.integer  "user_id"
 t.integer  "friend_id"
 t.datetime "created_at", :null => false
 t.datetime "updated_at", :null => false
end

add_index "user_friendships", ["user_id", "friend_id"], :name => "index_user_friendships_on_user_id_and_friend_id"

create_table "users", :force => true do |t|
 t.string   "first_name"
 t.string   "last_name"
 t.string   "profile_name"
 t.string   "email",                  :default => "", :null => false
 t.string   "encrypted_password",     :default => "", :null => false
 t.string   "reset_password_token"
 t.datetime "reset_password_sent_at"
 t.datetime "remember_created_at"
 t.integer  "sign_in_count",          :default => 0,  :null => false
 t.datetime "current_sign_in_at"
 t.datetime "last_sign_in_at"
 t.string   "current_sign_in_ip"
 t.string   "last_sign_in_ip"
 t.datetime "created_at",                             :null => false
 t.datetime "updated_at",                             :null => false
end

add_index "users", ["email"], :name => "index_users_on_email", :unique => true
add_index "users", ["reset_password_token"], :name => "index_users_on_reset_password_token", :unique => true

end
