如何以插入"形式传递字段的默认值?

How to pass a default value for a field in 'insert' form?

我正在使用Meteor的软件包:Autoform，Collections2和Simple-Schema.

I'm using Meteor's packages: Autoform, Collections2, and Simple-Schema.

我的过程是:

1. 用户在页面列表中选择一些值，然后
2. 打开插入"，我希望使用用户在上一步中选择的值来初始化一个字段.

无法弄清楚如何通过URL(或任何其他方式)传递参数. 问题是如何用值初始化表单.

Can't figure out how to pass a parameter withing URL (or any other way). The problem is how to initialize form with the value.

假设我有一个网址:

http://localhost:3000/activity/new/Sport

================ router.js:

=============== router.js:

...
Router.map(function () {
    ...
    this.route('newActivity', {
        path: '/activity/new/:tag',
        data: function() {
            Session.set('tag', this.params.tag);
            return null;
        }
    });
    ...

================ models/activity.js

=============== models/activity.js

...
Activities = new Meteor.Collection("activities", {
    schema: {
        title: {
            type: String,
            label: 'название'
        },
        ...
        tag: {
            type: String,
            label: 'тэг'
        }
    }
});

================= 模板/avtibity.js

================ templates/avtibity.js

...
Template.newActivity.helpers({
    defaultTag: function() {
        return Session.get('tag');
    }
});
...

================= templates/activity.html

================ templates/activity.html

...
<template name="newActivity">
    <h1>Create new Activity!</h1>
    {{#autoForm collection="Activities" id="insertActivityForm" type="insert"}}
        {{> afQuickField name="title"}}
        ...
        {{> afQuickField name="tag" value="   ??????    "}} // ? {{defaultTag}}
        ho ho ho {{defaultTag}}
    {{/autoForm}}
</template>

```

推荐答案

感谢Eric Dobbertin:

Thanks to Eric Dobbertin:

1. 您可以将value设置为等于返回所需值的助手({{> afQuickField name ="tag" value = valueHelper}})
2. 列表项您可以将doc设置为具有设置为所需值的对象.就像您要更新表格一样.
