我目前正在使用 postgres 枚举

CREATE TYPE http_action_enum AS ENUM ('GET', 'HEAD', 'POST', 'PUT', 'DELETE', 'CONNECT', 'OPTIONS', 'TRACE', 'PATCH');
CREATE TABLE IF NOT EXISTS response
(
    id                          UUID                PRIMARY KEY,
    http_action                 http_action_enum    NOT NULL
);

但是当我使用 ef 框架插入 postgres 数据库时，我不断遇到以下错误：

Exception data:
Severity: ERROR
SqlState: 42804
MessageText: column "destination" is of type source_dest_enum but expression is of type integer
Hint: You will need to rewrite or cast the expression.

当我检查响应数据类型时，它实际上是正确的枚举而不是整数。

存储库.cs

public async Task<Response> InsertRecord(Response response, CancellationToken cancellationToken)
{
      await dBContext.response.AddAsync(response, cancellationToken).ConfigureAwait(true); …
