If click submit data send ng2-file-upload - api

Question

How can I make the images uploads go with the data when I click the send button. Now I have a problem in the fact that when you select images are immediately downloaded to the server and there is a post request to api. I use Rails 5 for api
gallery.component.ts
name: string;
uploadFile: any;
hasBaseDropZoneOver: boolean = false;
uploadedFiles: any[] = [];
options: Object = {
url: 'http://localhost:3000/galleries'
};
sizeLimit = 2000000;
handleUpload(data): void {
if (data && data.response) {
data = JSON.parse(data.response);
this.uploadFile = data;
this.name = this.uploadFile.filename;
}
}
fileOverBase(e:any):void {
this.hasBaseDropZoneOver = e;
}
beforeUpload(uploadingFile): void {
if (uploadingFile.size > this.sizeLimit) {
uploadingFile.setAbort();
alert('File is too large');
}
}
shop.component.ts

    }
ngOnInit() {
this.getUserShops(this.authTokenService.currentUserData.id)
.subscribe((ownerShops) => {
if (ownerShops.length > 0) {
// User has at least 1 shop
this.router.navigate(['/profile'])
console.log(ownerShops.id);
} else {
// User has no shops
}
})
}
