Buffering Http State Provider

[thijsvanmenen]

Currently I use Ext.state.SessionProvider (from the Ext examples) but I want to switch to this implementation.

But is there a way to combine a CookieProvider with this one? I only know the logged in user from the cookie.

So I want to store the logged in user in the cookie, and the rest of the state in the database.

TIA.

Not really. There can be only one provider set in state manager. You need to access cookies some another way.

BTW, why do you want to switch from SessionProvider?

BTW, why do you want to switch from SessionProvider?

Because I am running into problems with cookie length.

[smudgeface]

why not just manually set a cookie

[jsakalos]

Yes, that is what I've meant.

@DamianHartin,

take a look at some of my examples or main page http://extjs.eu. There you can see working stateful ThemeCombo.

This example just save state.
But not restore state from server.
How to do this?

If i Use the Ext.state.CookieProvider in my app, the grid render with the last colum possition.
Its possible using Ext.ux.HttpProvider ???

No, CookieProvider is different provider. This page uses HttpProvider; just study how it is done there: http://cellactions.extjs.eu/

Tank you Saki.
But.. I create other class extend from CookieProvider with base in httpProvider

Ext.ux.HttpDBProvider = function(config) {
    Ext.ux.HttpDBProvider.superclass.constructor.call(this,config);
    this.path = "/";
    this.expires = new Date(new Date().getTime()+(1000*60*60*24*7)); //7 days
    this.domain = null;
    this.secure = false
    this.state={};
    Ext.apply(this, config);
}

Ext.extend(Ext.ux.HttpDBProvider, Ext.state.CookieProvider, {
    setCookie : function(name, value){
        var o = {
             url:this.saveUrl || this.url
            ,method:this.method
            ,scope:this
            ,params:{}
        };
        var params = Ext.apply({}, this.saveBaseParams);
        params[this.paramNames.id] = this.id;
        params[this.paramNames.session] = this.session;
        params[this.paramNames.user] = this.user;
        params[this.paramNames.name] = name;
        params[this.paramNames.data] = this.encodeValue(value);
        Ext.apply(o.params, params);
        Ext.Ajax.request(o);
    },
    readCookies : function(){
        var cookies = {};
        var o = {url:this.readUrl||this.url,method:this.method ,scope:this,params:{}
            ,success:function(response, options){
                var data = eval(response.responseText.split("\n")[0]);
                Ext.each(data, function(item) {
                    var tmp;
                    try {
                        tmp=this.decodeValue(item[this.paramNames.value]);
                    } catch(e){ dump(e);realAlert(e);return }
                    this.state[item[this.paramNames.name]] = tmp;
                }, this);
            }
        };
        var params = Ext.apply({}, this.readBaseParams);
        params[this.paramNames.id] = this.id;
        params[this.paramNames.session] = this.session;
        params[this.paramNames.user] = this.user;
        Ext.apply(o.params, params);
        Ext.Ajax.request(o);
        return
    },
    clearCookie : function(name){
        var o = {url:this.saveUrl||this.url,method:this.method,scope:this,params:{}};
        var params = Ext.apply({}, this.cleanBaseParams);
        params[this.paramNames.id] = this.id;
        params[this.paramNames.session] = this.session;
        params[this.paramNames.user] = this.user;
        params[this.paramNames.name] = name;
        Ext.apply(o.params, params);
        Ext.Ajax.request(o);
    }
}); 

this.cp=new Ext.ux.HttpDBProvider({id:"STATEPROVIDER",paramNames:{id:'CODIGO',name:'nome',value:'valor',user:'usuario',session:'SESSAO',data:'dados'},session:"",method:'POST',cleanBaseParams:{cmd:'cleanState'},readBaseParams:{cmd:'readState'},saveBaseParams:{cmd:'saveState'},readUrl:"",saveUrl:"",user:99,url:'jsonsql.php'});
Ext.state.Manager.setProvider(this.cp); 

on ready page I create the state object with readCookies;

this.cp.readCookies(); 

It's solve my problems.

Sorry, in that case you are on your own.
