Sencha Touch 2: Trying to create a login form - ruby-on-rails

Question

I am a 100% newb to Sencha and am trying to take a stab at re-factoring my company's mobile app.
Here is my app.js:
Ext.application({
name: 'RecruitTalkTouch',
views: ['Login'],
launch: function () {
Ext.Viewport.add([
{ xtype: 'loginview' }
]);
}
});
Login.js View:
Ext.define('RecruitTalkTouch.view.Login', {
extend: 'Ext.Container',
alias: "widget.loginview",
xtype: 'loginForm',
id: 'loginForm',
requires: ['Ext.form.FieldSet', 'Ext.form.Password', 'Ext.Label', 'Ext.Button' ],
config: {
title: 'Login',
items: [
{
xtype: 'label',
html: 'Login failed. Please enter the correct credentials.',
itemId: 'signInFailedLabel',
hidden: true,
hideAnimation: 'fadeOut',
showAnimation: 'fadeIn',
style: 'color:#990000;margin:5px 0px;'
},
{
xtype: 'fieldset',
title: 'Login Example',
items: [
{
xtype: 'textfield',
placeHolder: 'Email',
itemId: 'userNameTextField',
name: 'userNameTextField',
required: true
},
{
xtype: 'passwordfield',
placeHolder: 'Password',
itemId: 'passwordTextField',
name: 'passwordTextField',
required: true
}
]
},
{
xtype: 'button',
itemId: 'logInButton',
ui: 'action',
padding: '10px',
text: 'Log In'
}
]
}
});
Login.js Controller:
Ext.define('RecruitTalkTouch.controller.Login', {
extend: 'Ext.app.Controller',
config: {
refs: {
loginForm: 'loginForm'
},
control: {
'#logInButton': {
tap: 'onSignInCommand'
}
}
},
onSignInCommand: function(){
console.log("HELLO WORLD");
}
});
When I click the submit button, nothing happens. How can I hook up my submit button to listen for events (click, tap, etc) along with submitting the information to a backend API?

Answer 1

In app.js file of your application, add:
controllers: [
'Login'
]
in your application class. And for submitting information, call a Ajax request like this:
Ext.Ajax.request({
url: // api url..,
method: 'POST',
params: {
username: // get user name from form and put here,
password: // get password and ...
},
success: function(response) {
do something...
},
failure: function(err) {do ..}
});
from inside onSignInCommand() function.

Answer 2

You must activate your controller by adding it to the controllers option of your application class.
Then, to submit your data to the backend, you've got several options. You can use a form panel instead of your raw container, and use its submit method. Alternatively, you can use the Ext.Ajax singleton. In this case, you'll have to build the payload yourself. Finally, you can create a model with a configured proxy, and use its save method. This last way is probably the best for long term maintainability... Even if in the case of a simple login form, that may be a little bit overkill.
