Remote store filter with comparison parameter

[Michael Bogucki]

I try to filter my store remotly with comparision. Ext.util.Filter seems to have no comparison parameter (or at least i didn't found any). Something like the following code failed. The additional parameter isn't sent to the server.

 my_store.filter([{property: "date_to", value: myDate, comparison: "ls"}]);

Is there any way to add custom parameters to your filter which can be submited to the server? Or is there an other way to solve this issue?

I usually add the filter stuff to extraParams and handle that on the server instead of using the store filter.

hi
how to remove extra param when filter is clear?

[bluehipy]

store.on('filterschange', 
function(store, filters) {   
 if(!filters || !filters.length) {   
store.proxy.extraParams = {};
}
}); 

or something

This will erase all the extraparams, but I need to clean the filter params.

don't be lasy that filter management is fairly easy

I use bellow code for setting extraparam when filter is change

    onFilterUpdateRender:  function(grid,filters) {
        var jsonFilters = grid.getFilterData();
         if(!filters || !filters.length) {   
            this.store.proxy.extraParams = {}; 
        }
        Ext.each(jsonFilters, function(f) {
            var param = f.field;
            this.store.proxy.extraParams[param]=f.data.value;
        }, this);
    },

i set extra param of this store from controller with bellow code

    this.store.proxy.extraParams.id=1;

and finally the bellow code will erase all the extra params although I need to clean the filter params
how i can remove anly filter extra params?

on settting the filters keep track of names:

onFilterUpdateRender:  function(grid,filters) {        var jsonFilters = grid.getFilterData();         if(!filters || !filters.length) {               this.store.proxy.extraParams = {};         }this.store.myExtraFilters = this.store.myExtraFilters || [];        Ext.each(jsonFilters, function(f) {            var param = f.field;            this.store.proxy.extraParams[param]=f.data.value;            this.store.myExtraFilters.push(param);        }, this);    }, 

on cleaning the filters, you just delete what is stored in this.store.myExtraFilters

Ext.Array.each(this.store.myExtraFilters, function(f){  delete me.store.proxy.extraParams[f];});this.store.myExtraFilters =  [];
