我有以下scenario-合併多個遷移實體框架代碼優先
我在我加入了3個新的遷移分支機構的工作 - 爲約定我將它們命名爲
Migration A
Migration B
Migration C
當試圖合併master
原來有4個新的遷移,不按時間順序排列(從另一個分支合併)。我的意思是下面
new Migration from master 1
existing Migration in both branches
existing Migration in both branches
new Migration from master 2
new Migration from master 3
new Migration from master 4
existing Migration in both branches
existing Migration in both branches
當合並出現以下情形現在
new Migration from master 1
existing Migration in both branches
existing Migration in both branches
new Migration from master 2
new Migration from master 3
new Migration from master 4
existing Migration in both branches
existing Migration in both branches
Migration A
Migration B
Migration C
顯然實體框架不會放過,因爲它認爲該模式是錯誤的我更新數據庫 - 添加時新的遷移將生成從master
提到的4個新遷移中的更改。
真正的問題是,我不能恢復到現有的遷移,然後重新支架來更新元數據,因爲它們不是按時間順序排列 (如在另一個question每接受answer建議)。
我試圖update-database -target
回遷移之前new Migration from master 1
,然後Add-Migration <timestamp> new Migration from master 1
重新腳手架,但我得到了Unable to generate an explicit migration because the following explicit migrations are pending....
例外。
我真的不想增加空白遷移來解決這個問題,而是找到一個乾淨和良好的解決方案。
