Sencha 2 : Sync models with hasMany associations in LocalStorage
- by Alytrem
After hours and hours trying to do this, I need your help.
I have to models : Project and Task. A project hasMany tasks and a task belong to a project. Everyting works well if you don't use a store to save these models.
I want to save both tasks and projects in two stores (TaskStore and ProjectStore). These stores use a LocalStorage proxy.
I tried many things, and the most logical is :
Ext.define('MyApp.model.Task', {
extend: 'Ext.data.Model',
config: {
fields: [
{
name: 'name',
type: 'string'
},
{
dateFormat: 'd/m/Y g:i',
name: 'start',
type: 'date'
},
{
dateFormat: 'd/m/Y g:i',
name: 'end',
type: 'date'
},
{
name: 'status',
type: 'string'
}
],
belongsTo: {
model: 'MyApp.model.Project'
}
}
});
Ext.define('MyApp.model.Project', {
extend: 'Ext.data.Model',
alias: 'model.Project',
config: {
hasMany: {
associationKey: 'tasks',
model: 'MyApp.model.Task',
autoLoad: true,
foreignKey: 'project_id',
name: 'tasks',
store: {storeId: "TaskStore"}
},
fields: [
{
name: 'name',
type: 'string'
},
{
dateFormat: 'd/m/Y',
name: 'start',
type: 'date'
},
{
dateFormat: 'd/m/Y',
name: 'end',
type: 'date'
}
]
}
});
This is my "main" :
var project = Ext.create("MyApp.model.Project", {name: "mojo", start: "17/03/2011", end: "17/03/2012", status: "termine"});
var task = Ext.create("MyApp.model.Task", {name: "todo", start: "17/03/2011 10:00", end: "17/03/2012 19:00", status: "termine"});
project.tasks().add(task);
Ext.getStore("ProjectStore").add(project);
The project is added to the store, but task is not. Why ?!
