I'm having some trouble getting this to work. I have an image upload component that I want to set a controller property with so that I can later use it in a cropping component that finally will set a property that gets saved to my backend.
In index.hbs I render the image-input component, inside the image-component.hbs I have this setup
{{#if controller.image}}
<img src="{{controller.image}}" width="300">
<br>
{{/if}}
{{ file-input fileChanged="fileSelectionChanged"}}
In the file-input.js I have this
import Ember from 'ember';
export default Ember.TextField.extend({
type: 'file',
change: function(e) {
let self = this;
var inputFiles = e.target.files;
if (inputFiles.length < 1) {
return;
}
let inputFile = inputFiles[0];
let fileInfo = {
name: inputFile.name,
type: inputFile.type || 'n/a',
size: inputFile.size,
date: inputFile.lastModifiedDate ?
inputFile.lastModifiedDate.toLocaleDateString() : 'n/a',
};
var fileReader = new FileReader();
fileReader.onload = function(e) {
let fileReader = e.target;
fileInfo.dataUrl = fileReader.result;
self.sendAction('fileChanged', fileInfo);
};
let firstFile = e.target.files[0];
fileReader.readAsDataURL(firstFile);
}
});
In image-input.js I have this
import Ember from 'ember';
export default Ember.Component.extend({
actions: {
fileSelectionChanged: function(file) {
this.set('controller.image',file.dataUrl);
},
},
});
And finally in the controller I have it setup like this.
import Ember from 'ember';
export default Ember.Controller.extend({
formValid: false,
image: '',
actions: {
createFlyer: function() {
var newFlyer = this.store.createRecord('flyer', {
firstName: this.get('firstName'),
lastName: this.get('lastName'),
location: this.get('location'),
jobTitle: this.get('jobTitle'),
companyName: this.get('companyName'),
timeSpent: this.get('timeSpent'),
blurb: this.get('blurb'),
image: this.get('image')
});
newFlyer.save();
this.setProperties({
firstName: '',
lastName: '',
location: '',
jobTitle: '',
companyName: '',
timeSpent: '',
blurb: '',
})
}
}
});
This is the model
export default DS.Model.extend({
firstName: DS.attr('string'),
lastName: DS.attr('string'),
location: DS.attr('string'),
jobTitle: DS.attr('string'),
companyName: DS.attr('string'),
timeSpent: DS.attr('string'),
blurb: DS.attr('string'),
image: DS.attr('string')
});
Currently the component is setting the file property on the controller because when you browse and add an image the image tag shows up with the data: url properly added in the src attribute, so the property is being set, but when I save the form the content of the image
property is not being passed as the content of the data: url, it's just blank, like it's seeing the default.
Am I not setting the property up correctly?
For reference
I am using Ember-cli version 0.2.7
UPDATE
After applying Kingpin's suggestion below I am now getting this error in the console when trying to save to the backend.

Get rid of the controller references, just set it on the component, it's what is in scope in the view anyway.
