1. 渲染成散列，单个 partial 的引用
json.partial!'project', project: @project
# => {}
1.1 在散列 partial 外套一层
json.project do
json.partial! 'project', project: @project, full: true # 单个散列的传参
end
# => 格式如下
{
"project": {
"id": 1,
"picture": null,
"created_at": "2019-04-22 07:48:27 UTC",
"published": true,
"name": "测试项目01",
"purpose": "我是立项目的",
"stage": "立项中",
"industrial_level": "中试"
}
}
2. 渲染成数组
json.array! @projects, partial: 'project', as: :project
# => [{}, {}]
json.partial! 'project', collection: @projects, as: :project
# => [{}, {}]
json.partial! partial: 'project', collection: @projects, as: :project
# => [{}, {}]
注：
以上写法传参语法不同，详见下方
2.2 在数组外套一层
json.projects do
# 传递参数 full: true
json.array! @projects, partial: 'project', as: :project, locals: { full: true }
json.partial! 'project', collection: @projects, as: :project, full: true
json.partial! partial: 'project', collection: @projects, as: :project, locals: { full: true }
end
json.projects @projects, partial: 'project', as: :project, locals: { full: true }
# => 格式如下
{
"page_info": {
"total_items": 53,
"total_pages": 6
},
"projects": [{},{}]
}
其他：
- 在 partial 中获取当前参数
local_assigns
local_assigns.class # => Hash （知道这是一个散列，就随便你怎么玩啦）
local_assigns.keys # => [:project, :full, :json]
