流星：自定义自动窗体与对象数组 [英] Meteor: Custom AutoForm with array of objects

问题描述

我有一个SimpleSchema，其中包括对象的数组：

I have a SimpleSchema which includes an array of objects:

Things.attachSchema( new SimpleSchema({
    name: {
        type: String,
        label: "Name",
        max: 50
    },
    fields: { 
        type: [Object],
    },
    fields.$.name: {
        type: String
    },
    fields.$.amount: {
        type: Number
    }
}) )

我试图创建自定义表单利用afEachArrayItem的，但我可以不知道如何来指代对象的属性的数组中。

I'm trying to create custom form making use of afEachArrayItem, but I can't work out how to refer to the attributes of each object within the array.

我的模板看起来像这样（与HTML剥离出来）：

My template looks like this (with html stripped out):

{{#autoForm collection="things" id="myForm" }}
    {{> afQuickField name='schemaName'}}

    {{#afEachArrayItem name="fields"}}

        {{> afFieldInput name="name"}  
        {{> afFieldInput name="amount"}

    {{/afEachArrayItem}}

{{/autoForm}}

我应该在afFieldInputs被传递到名？

What should be passed to "name" in the afFieldInputs?

推荐答案

要访问数组中的对象的字段，可以使用：

To access the fields of the objects within the array, you can use:

this.current

因此​​，为了解决上面给出的实例中，使用：

So to fix the example given above, use:

{{#autoForm collection="things" id="myForm" }}
    {{> afQuickField name='schemaName'}}

    {{#afEachArrayItem name="fields"}}

        {{> afFieldInput name=this.current.name}}  
        {{> afFieldInput name=this.current.amount}}

    {{/afEachArrayItem}}

{{/autoForm}}

我不知道这是否是的正确的方式做到这一点，但它似乎工作。

I don't know if this is the correct way to do this, but it seems to work.
