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.
- Install
meteor add ostrio:autoform-files - Install
meteor add ostrio:files, if not yet installed - Add this config to
simpl-schemaNPM 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)
const Images = new FilesCollection({
collectionName: 'Images',
allowClientCode: true, // Required to let you remove uploaded file
onBeforeUpload(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', () => {
return Images.collection.find({});
});
}Note: If you don't use Mongo Collection instances (dburles:mongo-collection-instances), then the Images variable must be attached to Global scope. And has same name (case-sensitive) as collectionName option passed into FilesCollection#insert({collectionName: 'Images'}) method, Images in our case.
To start using dburles:mongo-collection-instances simply install it:
meteor add dburles:mongo-collection-instances- Define your schema and set the
autoformproperty 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
insertConfig: { // <- Optional, .insert() method options, see: https://github.com/VeliovGroup/Meteor-Files/wiki/Insert-(Upload)
meta: {},
isBase64: false,
transport: 'ddp',
streams: 'dynamic',
chunkSize: 'dynamic',
allowWebWorkers: true
}
}
}
}
});
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.:
{{> quickForm id="postsInsertForm" collection="Posts" type="insert"}}
<!-- OR -->
{{#autoForm id="postsInsertForm" collection="Posts" type="insert"}}
{{> afQuickField name="title"}}
{{> afQuickField name="picture"}}
<button type="submit" class="btn btn-primary">Insert</button>
{{/autoForm}}
<!-- OR with .insert() method options -->
<!-- See: https://github.com/VeliovGroup/Meteor-Files/wiki/Insert-(Upload) -->
{{#autoForm id="postsInsertForm" collection="Posts" type="insert"}}
{{> afQuickField name="title"}}
{{> afQuickField name="picture" transport="http" allowWebWorkers="false"}}
<button type="submit" class="btn btn-primary">Insert</button>
{{/autoForm}}{{#if Template.subscriptionsReady }}
{{> quickForm id="postsUpdateForm" collection="Posts" type="update" doc=getPost}}
{{/if}}
<!-- OR -->
{{#if Template.subscriptionsReady }}
{{#autoForm id="postsUpdateForm" 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.
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: Array,
label: 'Choose file' // <- Optional
},
"pictures.$": {
type: String,
autoform: {
afFieldInput: {
type: 'fileUpload',
collection: 'Images'
}
}
}
})Your custom file preview template data context will be:
- file - fileObj instance
picture: {
type: String,
autoform: {
afFieldInput: {
type: 'fileUpload',
collection: 'Images',
previewTemplate: 'myFilePreview'
}
}
}Your custom file upload template data context will be:
- file - FS.File instance
- progress
- status
- Other fields from
FileUploadinstance
picture: {
type: String,
autoform: {
afFieldInput: {
type: 'fileUpload',
collection: 'Images',
uploadTemplate: 'myFileUpload'
}
}
}<template name="myFilePreview">
<a href="{{file.link}}">{{file.original.name}}</a>
</template>This project wouldn't be possible without ostr.io.
