RequestPager sends all the attributes in server_api to the request as query string. However, sometime I want to exclude a parameter on some condition. This is how, i'm setting the param:
server_api: {
query: function () {
return this.searchQuery
},
type: function(){ return this.searchType }
}
If this.searchQuery
is empty, it makes the URL like ?query=&type=1
. But I don't want to send query
or type
when it's empty or when my some other condition fails.
I know the dirty way like:
if(!myCollection.searchQuery){
delete(myCollection.server_api.licensed);
}
But this is not maintainable. Because text time I've to create this function. So, I'm looking for a better way of doing this. Any Help?
If you look at how server_api
is used :
_.each(_.result(self, "server_api"), function(value, key){
if( _.isFunction(value) ) {
value = _.bind(value, self);
value = value();
}
queryAttributes[key] = value;
});
you'll see that it uses _.result
:
result
_.result(object, property)
If the value of the named property is a function then invoke it; otherwise, return it.
var object = {cheese: 'crumpets', stuff: function(){ return 'nonsense'; }}; _.result(object, 'cheese'); => "crumpets" _.result(object, 'stuff'); => "nonsense"
That means that you can make server_api
a function which returns the appropriate object.
