    Default Using the IndexedDB Proxy with the MVC Architecture

    Using the IndexedDB Proxy with the MVC Architecture


    I was receiving the following error when attempting to use this proxy in an app where I was following the MVC architecture.

    "Uncaught You are using a ServerProxy but have not supplied it with a url"


    I think my problem is that the model has no proxy, and hence the model manager assigned a default proxy with type "Ajax".

    My Model

    Ext.define('AM.model.User', {
    extend: 'Ext.data.Model',
    fields: [
    { name: 'id', type: 'int' },
    { name: 'firstName', type: 'string' },
    { name: 'lastName', type: 'string' },
    { name: 'dateOfBirth', type: 'date' },
    { name: 'email', type: 'string' },
    { name: 'testResult', type: 'string' }
    ],
    idProperty: 'id'
    });

    My Store

    Ext.define('AM.store.Users', {
    require: ['Ext.data.proxy.IndexedDB', 'Ext.data.proxy.IndexedDB', 'Ext.data.proxy.WebDB'],
    extend: 'Ext.data.Store',


    // destroy the store if the grid is destroyed
    autoDestroy: true,
    autoSync: true,
    autoLoad: true,
    model: 'AM.model.User',


    proxy: {
    type: 'idb',
    dbName: 'users',
    objectStoreName: 'user',
    dbVersion: '1.0',
    writer: {
    type: 'json',
    writeAllFields: false
    },
    initialData: [
    {
    dateOfBirth:"05 January 1970",
    email:"pg@fg.com",
    firstName:"Peter",
    id:1,
    lastName:"Griffen",
    testResult:"Pass"
    }, {
    dateOfBirth:"06 January 1970",
    email:"sg@fg.com",
    firstName:"Stewie",
    id:2,
    lastName:"Griffen",
    testResult:"NotSet"
    }
    ]
    }
    });



    My workaround to get this to work was to copy the proxy from the store into my model object, which is not ideal. i.e my model becomes

    Ext.define('AM.store.Users', {
    require: ['Ext.data.proxy.IndexedDB', 'Ext.data.proxy.IndexedDB', 'Ext.data.proxy.WebDB'],
    extend: 'Ext.data.Store',


    // destroy the store if the grid is destroyed
    autoDestroy: true,
    autoSync: true,
    autoLoad: true,
    model: 'AM.model.User',


    proxy: {
    type: 'idb',
    dbName: 'users',
    objectStoreName: 'user',
    dbVersion: '1.0',
    writer: {
    type: 'json',
    writeAllFields: false
    },
    initialData: [
    {
    dateOfBirth:"05 January 1970",
    email:"pg@fg.com",
    firstName:"Peter",
    id:1,
    lastName:"Griffen",
    testResult:"Pass"
    }, {
    dateOfBirth:"06 January 1970",
    email:"sg@fg.com",
    firstName:"Stewie",
    id:2,
    lastName:"Griffen",
    testResult:"NotSet"
    }
    ]
    }
    });

    Is there a better solution to this problem? Quite new to ExtJs!!!

    Default Can't create a second objectStore in the same DB

    Can't create a second objectStore in the same DB


    Hello, after all, I'll like to give you credit for this proxy's implementation, it's great.

    I'm using ExtJS 4.1

    I've created a Model that use BrowserDB proxy (ID with some InitialData and it works fine, but, when I try to define another Model with a proxy "browserdb" with a diferent objectStoreName, but using the same db, it's not been created, only when I change the dbName property in the configuration, works, but for me doesn't have too much sense...
    Code:
    // ****************** Always works ********************
    //Model
    Ext.define('app.model.Customer', {
        extend: 'Ext.data.Model',
        fields: [
           ...
        ],
    	proxy      : {
    	    type            : 'browserdb',
    	    dbName          : 'db1',
    	    objectStoreName : 'customer',
    	    writer          : {
    	        type           : 'json',
    	        writeAllFields : false
    	    },
    	    initialData     : [{
    	            ...
    	        },{
    	            ...
    	     } ]
    	}
    });
    
    // Store...
    Ext.define('app.store.Customers', {
        extend	: 'Ext.data.Store',
        autoDestroy: true,
        autoSync: true,
        autoload: true,
        requires: ['app.model.Customer'],
        config	: {
        	model	: 'app.model.Customer',
        	storeId	: 'Customers'
        }
    });
    // *****************************************************
    
    // Second Model
    // ****************** This never works *********************
    // Model...
    Ext.define('app.model.Product', {
        extend: 'Ext.data.Model',
        fields: [
            ...
        ],
    	proxy      : {
    	    type            : 'browserdb',
    	    dbName          : 'db1',
    	    objectStoreName : 'products',
    	    writer          : {
    	        type           : 'json',
    	        writeAllFields : false
    	    }
    	}
    });
    
    //Store...
    Ext.define('app.store.Products', {
    	extend	: 'Ext.data.Store',
    	autoDestroy: true,
    	autoSync: true,
    	autoload: true,
    	requires: ['app.model.Product'],
    	config	: {
    		model	: 'app.model.Product',
    		storeId	: 'Products'
    	}
    });
    
    // *****************************************************
    
    // Created in another DB
    // ******************** This works ************************
    Ext.define('app.model.Product', {
        extend: 'Ext.data.Model',
        fields: [
            ...
        ],
    	proxy      : {
    	    type            : 'browserdb',
    	    dbName          : 'db2',
    	    objectStoreName : 'products',
    	    writer          : {
    	        type           : 'json',
    	        writeAllFields : false
    	    }
    	}
    });
    // *****************************************************
    
    // At last the insertion
    
    var store = Ext.create('app.store.Products');
    var product = Ext.create('app.model.Product', {
        ...
    });
    product.save();
    store.insert(0,product);
    store.save();
    Please, help...

    Hi,

    I tried to use the example provided in https://github.com/grgur/Ext.data.proxy.IndexedDB
    But this standalone code throws the error:
    Code:
    Uncaught TypeError: Object #<IDBDatabase> has no method 'setVersion' Ext.data.proxy.IndexedDB.js:127
    request.onsuccess   Ext.data.proxy.IndexedDB.js:127
    Does someone has an idea how I can fix this? Or does soneone has the same problem?

    Best regards,
    Tobias
