【问题描述】:
我得到的例外是“ActiveRecord::ConnectionNotEstablished:ActiveRecord::Base 没有连接池”。我真的在这个池子的最深处(没有双关语)。我真的不了解连接和连接池处理,即使我研究过这个问题。我假设这可能与 Cucumber 内部的范围相关,但我不知道。感谢您提供任何和所有帮助。
详情如下:
当我从 Then 子句执行计数时发生异常:
WorkTable.where('? is not null',col['COLUMN_NAME']).count
如果我直接通过连接发送sql不会发生:
WorkTable.connection.select_all(st.encode('utf-8')).first['nulls']
我的场景如下:
Scenario: CompanyMaster test for null value
Given table dbo.base_table in stage
Then these columns are expected to be not null
| COLUMN_NAME | nulls |
| id | 0 |
| company_name | 0 |
我在我的 env.rb 中建立我的班级:
class WorkTable < ActiveRecord::Base
end
ActiveRecord::Base.configurations = YAML.load_file(yaml) # yaml is database.yml file name
我在 Given 子句中建立连接:
Given(/^table (\w+)\.?([\w_]+) in (\w+)(?: as (\w+))?$/) do |schema,name,env,id|
@sc_name = schema_file_name(schema,name)
WorkTable.logger.info title_line("* Active table(#{@sc_name}) *")
case id
# ActiveRecord::Base.configurations[env]
...
else
WorkTable.table_name = @sc_name
WorkTable.establish_connection(env.to_sym)
# ary = get_tables(WorkTable,schema:schema)
# expect( ary.any?{|s| s.casecmp(name)==0 } ).to eq(true)
end
end
我在 Then 子句中执行我的测试:
Then(/^these columns are expected to be not null$/) do |columns|
# expected is an instance of Cucumber::Ast::Table
WorkTable.logger.info title_line('Columns cannot be null')
results = []
columns.hashes.each {|col|
results << {
'COLUMN_NAME' => col['COLUMN_NAME'],
'nulls' => WorkTable.where('? is not null',col['COLUMN_NAME']).count.to_s
}
}
columns.diff!(results,surplus_row: false)
end
是 WorkTable.where 抛出“ActiveRecord::ConnectionNotEstablished: No connection pool for ActiveRecord::Base”。同样,如果我使用 WorkTable.connection 方法,我不明白。此外,如果我将所有 function 代码复制到单个 ruby 脚本,它执行得很好。
当我“pp WorkTable.connection”时看到以下内容:
#<ActiveRecord::ConnectionAdapters::SQLServerAdapter version: 4.2.2, mode: dblib, azure: false>
当我“pp WorkTable.connection_pool”时,我看到以下内容:
#<ActiveRecord::ConnectionAdapters::ConnectionPool:0x42f5238
@automatic_reconnect=true,
@available=
#<ActiveRecord::ConnectionAdapters::ConnectionPool::Queue:0x42f4f20

Ruby 1.9.3、activerecord (4.2.0)、activerecord-sqlserver-adapter (4.2.2) 和 cucumber (1.3.18)。还有 sql server 2014 [这对我来说是个麻烦]。
感谢您的时间和考虑。 dvn
== 更多细节 ==
忽略 sql-server 引用。当我重新配置以使用 Sqlite 时,我得到了同样的异常。所以它与db平台无关。
