该角色不存在

Error message

该角色不存在

What it means

DeleteAuthority loads the role (with preloaded Users) before deleting; if the First() returns gorm.ErrRecordNotFound it returns "该角色不存在". The role cannot be deleted because it does not exist in sys_authorities at the time of the call.

Solutions

1. Refresh the role list and confirm the role is already gone — no action needed.
2. Verify the authorityId in the request matches an existing role.
3. Check you are connected to the intended database/environment.

Example fix

// before: blind delete that can double-fire
await Promise.all(ids.map(id => deleteAuthority({ authorityId: id })))

// after: dedupe and tolerate already-deleted
await Promise.all([...new Set(ids)].map(async id => {
  try { await deleteAuthority({ authorityId: id }) } catch (e) {
    if (!String(e.msg).includes('该角色不存在')) throw e
  }
}))

const roles = (await getAuthorityList()).data.list
if (!roles.some(r => r.authorityId === id)) throw new Error('角色已不存在，跳过删除')

try {
  await deleteAuthority({ authorityId: id })
} catch (e) {
  if (String(e?.msg).includes('该角色不存在')) {
    ElMessage.info('角色已被删除，无需重复操作')
    refreshList()
  } else { throw e }
}

When it happens

Trigger: DELETE /authority/deleteAuthority with an authorityId absent from sys_authorities — double-delete (same role removed twice), deleting an already-deleted role from a stale page, or deleting a role from the wrong environment/database.

Common situations: Concurrent admins deleting the same role; frontend list not refreshed after another deletion; scripts replaying deletion requests; environment mismatch (staging ID used against production DB).
