[英]Meteor get autovalue _id inside collection
I have this field which is working as I want 我有这个领域正在我想要
tagSlug: {
type: String,
label: "slug",
optional:true,
autoValue: function() {
if (this.siblingField('tag').isSet) {
return URLify2(this.siblingField('tag').value);
}
}
}
But I also want to make another field named nameSlug
which needs two fields to be slugged, _id
and title
if I use this.siblingField('title').value
I get title value but nothing hapens if I use this.siblingField('_id').value
this may be because _id
is not a field inside the form... The final output I want is something like this this-is-awesome-title-xDux1if
the last param is _id
cutted to 6 or 7 characters I don't know what I will do yet in order to not create large slug strings, but you get the idea. 但是我还想创建另一个名为nameSlug
字段,如果使用this.siblingField('title').value
,则需要输入两个字段_id
和title
this.siblingField('title').value
我得到标题值,但是如果使用this.siblingField('_id').value
这可能是因为_id
不是表单中的字段...如果最后一个参数被_id
this-is-awesome-title-xDux1if
6或7个字符,我想要的最终输出就是这个this-is-awesome-title-xDux1if
我不知道我该怎么做才能不创建大段子字符串,但是您明白了。
So basically what I want is to access _id
field from inside collection for autoValue
another field. 所以基本上我想要从autoValue
内部集合中访问_id
另一个字段。
I'm using meteor-autoform
so I didn't create any Whatever.insert
method because they're created automaticaly. 我使用的是meteor-autoform
所以我没有创建任何Whatever.insert
方法,因为它们是自动创建的。
如果不需要存储它,则可以使用virtualfields或collection-helpers
