Using one autoForm, I need to insert data into two collections - mongodb

Question

I am currently working on an inventory system that takes a Part Collection, and a Purchase Collection as the backbone of the application. Each part much have a corresponding purchase. I.E a Part must have a partId, serial number, and cost number associated with it. I am using Meteor.js with coffeescrip, jade, and Graphr. I can insert into each collection individually, but they do not seem connected. I have set up the linkers between the two connection but I am a little lost as to where to go next
here is a snippet of the collections
Purchase Collection
PurchaseInventory.schema = new SimpleSchema
partId:
type:String
optional:true
serialNum:
type:Number
optional:true
costNum:
type:Number
optional:true
Parts Collection/schema
Inventory.schema = new SimpleSchema
name:
type:String
optional:true
manufacturer:
type:String
optional:true
description:
type:String
optional:true
parts query
export getInventory = Inventory.createQuery('getInventory',
$filter: ({ filters, options, params }) ->
if params.filters then Object.assign(filters, params.filters)
if params.options then Object.assign(options, params.options)
return { filters, options , params }
name:1
manufacturer:1
description:1
pic:1
purchase:
partId:1
)
purchase query
export getPurchase = PurchaseInventory.createQuery('getPurchase',
$filter: ({ filters, options, params }) ->
if params.filters then Object.assign(filters, params.filters)
if params.options then Object.assign(options, params.options)
return { filters, options , params }
serial:1
cost:1
date:1
warrentyDate:1
userId:1
)
Linkers
//Parts
Inventory.addLinks
purchase:
collection:PurchaseInventory
inversedBy:"part"
//purchases
PurchaseInventory.addLinks
part:
type:'one'
collection:Inventory
field:'partId'
index: true
And finally the Jade/Pug auto form
+autoForm(class="inventoryForm" schema=schema id="inventoryInsertForm" validation="blur" type="method" meteormethod="inventory.insert")
.formGroup
+afQuickField(name="name" label="Name")
+afQuickField(name="manufacturer" label="Manufacturer")
+afQuickField(name="description" label="Description")
button#invenSub(type="submit") Submit
To reiterate my goal is to have each item in parts to have a link to its corresponding purchase data.

The most straight forward way is to use autoform form type normal and create a custom event handler for the submit event (alternatively you can use the AutoForm hooks onSubmit). From there you can use the AutoForm.getFormValues API function to get the current document.
Since I am not into Coffeescript I would provide the following as Blaze/JS code but I think it should give you the idea:
{{# autoForm type="normal" class="class="inventoryForm" schema=schema id="inventoryInsertForm" validation="blur"" schema=schema id="insertForm" validation="blur" }}
<!-- your fields -->
{{/autoForm}}
/**
* validates a form against a given schema and returns the
* related document including all form data.
* See: https://github.com/aldeed/meteor-autoform#sticky-validation-errors
**/
export const formIsValid = function formIsValid (formId, schema) {
const { insertDoc } = AutoForm.getFormValues(formId)
// create validation context
const context = schema.newContext()
context.validate(insertDoc, options)
// get possible validation errors
// and attach them directly to the form
const errors = context.validationErrors()
if (errors && errors.length > 0) {
errors.forEach(err => AutoForm.addStickyValidationError(formId, err.key, err.type, err.value))
return null
} else {
return insertDoc
}
}
Template.yourFormTempalte.events({
'submit #insertForm' (event) {
event.preventDefault() // important to prevent from reloading the page!
// validate aginst both schemas to raise validation
// errors for both instead of only one of them
const insertDoc = formIsValid('insertForm', PurchaseInventory.schema) && formIsValid('insertForm', Inventory.schema)
// call insert method if both validations passed
Meteor.call('inventory.insert', insertDoc, (err, res) => { ... })
Meteor.call('purchaseInventory.insert', insertDoc, (err, res) => { ... })
}
})
Note, that if you need both inserts to be successful on the server-side you should write a third Meteor method that explicitly inserts a single doc in both collection in one method call. If you have Mongo version >= 4 you can combine this with transactions.
