    Default Adding Parameters to the PagingToolbar

    Adding Parameters to the PagingToolbar


    My PagingToolBar isn't sending the parameters I specify in my store.

    When my application loads, I'm fetching records from my services.

    Code:
    PostProxy.prototype.getPosts = function() {
        Ext.create('Ext.data.Store', {
            model:'Post',
            pageSize:50,
            autoLoad:false,
            storeId:'PostStore',
            baseParams:{ getall:true, profile:true, blogid:3 },
          
        });
       
       var store = Ext.StoreMgr.lookup('PostStore');
       store.on({'datachanged':this.onDataChanged});
       store.on({'load':this.onPostsRetrieved});
       
        // These parameters are needed on every GET request
        store.load({
            params : {
                start : 0,
                limit : 50,
                getall:true,
                profile:true,
                blogid:3
            }
        });   
    };
    A notification is sent to my GridPanel when the data load. If my grid hasn't been created, it's created:

    Code:
    buildBlogPosts : function() {
        console.log('buildBlogPosts:::::');
        var store = Ext.StoreMgr.lookup('PostStore'); // Store has correct baseParams
    
    
        var gp = Ext.getCmp('postPanel');
        if (!gp) {
            
            var gp = Ext.create('Ext.grid.Panel', {
                id:'postPanel',
                store : store,
                autoHeight : true,
                layout: {
                    type:'fit',
                    align:'stretch'
                },
                viewConfig : {
                    trackOver : false,
                    stripeRows : false,
                },
                listeners : {
                    itemclick : function(grid, item) {
                        Ext.getCmp('east').PostSelected.dispatch(item);
                    }
                },
                columns : [{
                    header : 'Title',
                    dataIndex : 'entry_title',
                    flex : 1
                }],
                bbar : Ext.create('Ext.PagingToolbar', {
                    id:'paginator',
                    store : store, // same store grid is using
                    displayInfo : true
                })
            });
            
            Ext.getCmp('cards').add(gp);
            
            // Is this where I intercept the GET and add the extra parameters??
            Ext.getCmp('paginator').on('beforechange', function(itm) {
                console.log('BEFORECHANGE');
                console.dir(itm);
            });
            
            Ext.getCmp('cards').getLayout().setActiveItem(1);
            
        }
    }
    When I click the 'next' button on PagingToolBar and a new request is sent, I don't see my params in the querystring. I just see the start, page and limit variables.

    Why aren't my params being sent when the page changes?

    Thanks in advance!

    Have you tried using extraParams on the proxy?

    Not sure what proxy you are using, but here is link to the Ajax proxy

    I see, you have to add them to the proxy. Thanks!

    [Solved]
    Code:
    
    store.getProxy().extraParams.getall = true;
    store.getProxy().extraParams.profile = true;
    store.getProxy().extraParams.blogid = 1;
    If you want to change the params each time, you'd have to use:

    Code:
    store.on('beforechange', function() {
        store.getProxy().extraParams.getall = <SOMEVAL>;
        store.getProxy().extraParams.profile = <SOMEVAL>;
        store.getProxy().extraParams.blogid = <SOMEVAL>;     
    });
