Steedos Object Buttons | Steedos 对象按钮

Overview | 概述

Object buttons are custom actions displayed on record pages or list views. They are defined as .button.yml files using YAML with inline Amis JSON schema for UI and event handling.

对象按钮是显示在记录页面或列表视图上的自定义操作。使用 .button.yml 文件定义，通过内联 Amis JSON schema 配置 UI 和事件处理。

Button Structure | 按钮结构

⚠️ 关键规则：amis_schema 最外层必须是 service amis_schema 的根节点 必须 是 {"type": "service", "body":...}， 将实际按钮放在 body 中。如果最外层直接是 button，按钮将无法显示。 ⚠️ Critical: amis_schema root MUST be a service wrapper. The actual button goes inside body. A bare button at the root will not render.

# objects/orders/buttons/submit_order.button.yml
name: submit_order
label: Submit for Approval
type: amis_button
on: record_only
is_enable: true
visible: true
locked: false
amis_schema: |-
  {
    "type": "service",
    "body": {
      "type": "button",
      "label": "Submit for Approval",
      "level": "primary",
      "onEvent": {

Hiding Standard Buttons | 隐藏标准按钮

Override standard buttons by creating a .button.yml with visible: false:

# objects/orders/buttons/standard_delete.button.yml
name: standard_delete
visible: false

# objects/orders/buttons/standard_edit.button.yml
name: standard_edit
visible: false

# objects/orders/buttons/standard_new.button.yml
name: standard_new
visible: false

# objects/orders/buttons/standard_delete_many.button.yml
name: standard_delete_many
visible: false

Amis Action Types | Amis 操作类型

Common actionType values used in button events:

Accessing Record Data in Amis Schema | 在 Amis Schema 中访问记录数据

On record detail pages (on: record_only / record), the Amis data scope automatically includes:

• recordId — Current record's _id
• All fields of the current record (e.g., status, name, amount)
• context.user.user — Current user ID

In Amis Template Expressions | 在 Amis 模板表达式中

Use ${variable} syntax for visibleOn, disabledOn, value, etc.:

{
  "visibleOn": "${status == 'draft'}",
  "visibleOn": "${ARRAYINCLUDES(approvers, '${context.user.user}')}",
  "value": "${name} - copy"
}

In requestAdaptor | 在发送适配器中

Use context.recordId to get the current record's _id:

{
  "requestAdaptor": "api.data = { id: context.recordId }",
  "requestAdaptor": "api.data = { id: context.recordId, reason: api.body.reject_reason }"
}

• context.recordId — Current record _id (recommended)
• context.user.user — Current user ID
• api.body.fieldName — Access form field values (in dialog forms)

API v6 Response Structures | API v6 响应数据结构

⚠️ You MUST use the correct response structure when writing adaptor. Different endpoints return DIFFERENT formats.

Button Adaptor Patterns | 按钮适配器模式

// Function returns { message: "Order approved" }
// adaptor extracts message from the raw return value (payload = function return)
{
  "adaptor": "return { ...payload, msg: payload.message || 'Success' }",
  "messages": { "success": "${msg}" }
}

// Function returns { success: true, data: { orderId: "..." } }
// adaptor accesses data directly from the raw return value
{
  "adaptor": "return { ...payload, msg: 'Order ' + payload.data.orderId + ' processed' }",
  "messages": { "success": "${msg}" }
}

// List query in dialog — response is { data: [...], totalCount: N }
// Items are in payload.data array
{
  "adaptor": "return { data: { items: payload.data, total: payload.totalCount } }"
}

⚠️ payload in adaptor IS the raw API response. For function endpoints, payload = whatever the function returns. For data endpoints, payload = {data: [...], totalCount: N} (list) or a raw document (single/create/update).

📖 For complete API v6 documentation (all endpoints, filter operators, complex filters, authentication), load the steedos-server-api skill. 📖 如需 API v6 完整文档（所有端点、筛选运算符、复合筛选、认证方式），请加载 steedos-server-api 技能。

Best Practices | 最佳实践

1. amis_schema root MUST be service: Always wrap the button in {"type":"service","body":{...}}. A bare button at the root will not render. （amis_schema 根节点必须是 service，否则按钮无法显示）
2. Always pass skip and top for list queries: If the button's AJAX or dialog fetches data from /api/v6/data/, always include skip and top parameters. Example: /api/v6/data/orders?skip=0&top=100（如果按钮获取 /api/v6/data/ 列表数据，必须包含 skip 和 top 参数）
3. Use functions for business logic: Buttons should call server-side functions via AJAX, not embed business logic in the client
4. Provide confirmation: Use confirmText for destructive actions
5. Reload after action: Always reload record detail or list view after successful action
6. Conditional visibility: Use visibleOn to show buttons only when appropriate
7. Bilingual labels: Provide both English and Chinese labels where needed
