Autoform File

Description

Upload and manage files with autoForm via ostrio:files. This package was ported from yogiben:autoform-file to use with ostrio:files instead of the already deprecated CollectionFS.

Quick Start:

Install meteor add ostrio:autoform-files
Install meteor add ostrio:files, if not yet installed
Add this config to simpl-schema NPM package (depending of the language that you are using):

SimpleSchema.setDefaultMessages({
  initialLanguage: 'en',
  messages: {
    en: {
      uploadError: '{{value}}', //File-upload
    },
  }
});

Create your Files Collection (See ostrio:files)

var Images = new FilesCollection({
  collectionName: 'Images',
  allowClientCode: true, // Required to let you remove uploaded file
  onBeforeUpload: function (file) {
    // Allow upload files under 10MB, and only in png/jpg/jpeg formats
    if (file.size <= 10485760 && /png|jpg|jpeg/i.test(file.ext)) {
      return true;
    } else {
      return 'Please upload image, with size equal or less than 10MB';
    }
  }
})

if (Meteor.isClient) {
  Meteor.subscribe('files.images.all');
}

if (Meteor.isServer) {
  Meteor.publish('files.images.all', function () {
    return Images.collection.find({});
  });
}

Note: Images variable must be attached to Global scope. And has same name (case-sensitive) as collectionName option passed into FilesCollectio#insert({collectionName: 'Images'}) method, Images in our case.

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',
        uploadTemplate: 'uploadField' // <- Optional
        previewTemplate: 'uploadPreview' // <- Optional
      }
    }
  }
});

Posts.attachSchema(Schemas.Posts);

The collection property must be the same as name of your FilesCollection (case-sensitive), Images in our case.

Generate the form with {{> quickform}} or {{#autoform}} e.g.:

Insert mode:

{{> 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}}

Update mode:

{{#if Template.subscriptionsReady }}
  {{> quickForm collection="Posts" type="update" doc=getPost}}
{{/if}}
<!-- OR -->
{{#if Template.subscriptionsReady }}
  {{#autoForm collection="Posts" type="update" doc=getPost}}
    {{> afQuickField name="title"}}
    {{> afQuickField name="picture"}}
    <button type="submit" class="btn btn-primary">Update</button>
  {{/autoForm}}
{{/if}}

Autoform should be wrapped in {{#if Template.subscriptionsReady }} which makes sure that template level subscription is ready. Without it the picture preview won't be shown. You can see update mode example here.

Multiple images //does not support yet

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'
      }
    }
  }
})

Custom file preview

Your custom file preview template data context will be:

file - fileObj instance

picture: {
  type: String,
  autoform: {
    afFieldInput: {
      type: 'fileUpload',
      collection: 'Images',
      previewTemplate: 'myFilePreview'
    }
  }
}

Custom upload template

Your custom file upload template data context will be:

file - FS.File instance
progress
status
Other fields from FileUpload instance

picture: {
  type: String,
  autoform: {
    afFieldInput: {
      type: 'fileUpload',
      collection: 'Images',
      uploadTemplate: 'myFileUpload'
    }
  }
}

<template name="myFilePreview">
  <a href="{{file.link}}">{{file.original.name}}</a>
</template>
