Meteor autoform file

Quick Start

1) Install meteor add yogiben:autoform-file

2) Create your collectionFS (See collectionFS)

@Images = new FS.Collection("images",
  stores: [new FS.Store.GridFS("images", {})]
)

3) Make sure the correct allow rules & subscriptions are set up on the collectionFS

Images.allow
  insert: (userId, doc) ->
    true
  download: (userId)->
    true

and

Meteor.publish 'images', ->
  Images.find()

and in your router.coffee

  @route "profile",
    waitOn: ->
      [
        Meteor.subscribe 'images'
      ]

4) Define your schema and set the autoform property like in the example below

Schemas = {}

@Posts = new Meteor.Collection('posts');

Schemas.Posts = new SimpleSchema
  title:
    type: String
    max: 60

  picture:
    type: String
    autoform:
      afFieldInput:
        type: 'fileUpload'
        collection: 'Images'
        label: 'Choose file' # optional

Posts.attachSchema(Schemas.Posts)

The collection property is the field name of your collectionFS.

5) Generate the form with {{> quickform}} or {{#autoform}}

e.g.

{{> quickForm collection="Posts" type="insert"}}

or

{{#autoForm collection="Posts" type="insert"}}
{{> afQuickField name="title"}}
{{> afQuickField name="picture"}}
<button type="submit" class="btn btn-primary">Insert</button>
{{/autoForm}}

###Multiple images### If you want to use an array of images inside you have to define the autoform on on the schema key

Schemas.Posts = new SimpleSchema
  title:
    type: String
    max: 60

  pictures:
    type: [String]
    label: 'Choose file' # optional

  "pictures.$":
    autoform:
      afFieldInput:
        type: 'fileUpload',
        collection: 'Images'

###Security & optimization### The above example is just a starting point. You should set your own custom allow rules and optimize your subscriptions.

Customization

You can customize the button / remove text.

Defaults:

{{> afFieldInput name="picture" label="Choose file" remove-label="Remove"}}

Also it is possible to customize accept attribute

add it in your schema definition:

picture:
  type: String
  autoform:
    afFieldInput:
      type: 'fileUpload'
      collection: 'Images'
      accept: 'image/*'
      label: 'Choose file' # optional

Upload progress bar

By default FS.UploadProgressTemplate from cfs:ui package is used to display upload progress. You can specify your own template with uploadProgressTemplate option, e.g.

picture:
  type: String
  autoform:
    afFieldInput:
      type: 'fileUpload'
      collection: 'Images'
      uploadProgressTemplate: 'myUploadProgressTemplate'

Custom file preview

Your custom file preview template data context will be:

  • file - FS.File instance
  • atts - autoform atts
picture:
  type: String
  autoform:
    afFieldInput:
      type: 'fileUpload'
      collection: 'Images'
      previewTemplate: 'myFilePreview'
<template name="myFilePreview">
  <a href="{{file.url}}">{{file.original.name}}</a>
</template>

Custom select/remove file buttons

Remember to add js-af-select-file and js-af-remove-file classes to nodes which should fire an event on click.

picture:
  type: String
  autoform:
    afFieldInput:
      type: 'fileUpload'
      collection: 'Images'
      selectFileBtnTemplate: 'mySelectFileBtn'
      removeFileBtnTemplate: 'myRemoveFileBtn'
<template name="mySelectFileBtn">
  <button type="button" class="js-af-select-file">Upload file</button>
</template>

<template name="myRemoveFileBtn">
  <button type="button" class="js-af-remove-file">Remove</button>
</template>

Callbacks

onBeforeInsert - can be used to modify file (remember to return fileObj)

onAfterInsert - called after insert with two arguments: error object and file object

Please note that callback properties are functions that return callbacks. This is because autoform evaluates function attributes first.

picture:
  type: String
  autoform:
    afFieldInput:
      type: 'fileUpload'
      collection: 'Images'
      onBeforeInsert: ->
        (fileObj) ->
          fileObj.name 'picture.png'
          fileObj
      onAfterInsert: ->
        (err, fileObj) ->
          if err
            alert 'Error'
          else
            alert 'Upload successful'
