db：s上的SQLException：使用Rails加载

时间：2013-05-24 18:55:19

标签： ruby-on-rails-3 sqlite database-schema

我一直在研究一个小而复杂的Rails应用程序，它具有多个has_and_belongs_to_many关系。它是开源的，代码是here。一切都运行良好，但最近我添加了一个新的HABTM关系迁移，并且rspec测试开始失败。 Rake：db：migrate正在运行（问题是在本地工作），只是没有进行测试。在运行db：test：load --trace时，我收到以下错误：

我的schema.rb文件如下：

# encoding: UTF-8
# This file is auto-generated from the current state of the database. Instead
# of editing this file, please use the migrations feature of Active Record to
# incrementally modify your database, and then regenerate this schema definition.
#
# Note that this schema.rb definition is the authoritative source for your
# database schema. If you need to create the application database on another
# system, you should be using db:schema:load, not running all the migrations
# from scratch. The latter is a flawed and unsustainable approach (the more migrations
# you'll amass, the slower it'll run and the greater likelihood for issues).
#
# It's strongly recommended to check this file into your version control system.

ActiveRecord::Schema.define(:version => 20130519192155) do

  create_table "distributions", :force => true do |t|

非常感谢任何帮助或信息。我在网上搜索这些错误已经有一段时间了，但在网上发现的很少。

对我有用的是删除schema.rb，它是架构定义文件。

（此文件中的第一段注释建议删除它并生成一个新注释，而不是编辑它。）

然后运行rake db:migrate，执行所有迁移并重新创建schema.rb文件。

答案 1 :(得分：1)

我也得到了类似的错误，我也不知道。但是当我删除这些代码时，在这种情况下，

尝试删除这些行： 

create_table "sqlite_sp_functions", :id => false, :force => true do |t|
  t.text "name"
  t.text "text"
end

# Could not dump table "sqlite_stat1" because of following StandardError
#   Unknown type '' for column 'tbl'

# Could not dump table "sqlite_stat3" because of following StandardError
#   Unknown type '' for column 'tbl'

create_table "sqlite_vs_links_names", :id => false, :force => true do |t|
  t.text "name"
  t.text "alias"
end

create_table "sqlite_vs_properties", :id => false, :force => true do |t|
  t.text "parentType"
  t.text "parentName"
  t.text "propertyName"
  t.text "propertyValue"
end

create_table "sqlite_vsp_diagrams", :id => false, :force => true do |t|
  t.text "name"
  t.text "diadata"
  t.text "comment"
  t.text "preview"
end

然后rake test:prepare可能有用。

答案 2 :(得分：0)

将以下配置行添加到config/application.rb或config/environments/development.rb：

ActiveRecord::SchemaDumper.ignore_tables = /^sqlite_*/

这将忽略以＆＃34; sqlite _＆＃34;开头的所有表格。在架构转储期间在数据库中。
