我相信您对secretsanta表名的怀疑是正确的.

I believe you were right on in your suspicion about the secretsanta table name.

除非您在secretsanta模型上设置了table_name，否则Rails会查找名为secretsantas的表.如果应用程序以前可以运行，我猜该表实际上名为secretsantas.

Unless you've set a table_name on your secretsanta model, rails will look for a table named secretsantas. If the application was working before, I'd guess that the table actually is named secretsantas.

要列出可用表，请运行:

To list the available tables, run:

tables = ActiveRecord::Base.connection.tables

嗯，这是问题所在:

'Secretsanta'.pluralize
=> "Secretsanta"

尝试在模型中指定表名:

Try specifying the table name in your model:

class Secretsanta < ActiveRecord::Base
  self.table_name = "secretsantas"
end
