ExtJS 5如何在模型中动态创建字段

Question

I have plenty of fields that I want to add to my model. I fount this thread Dynamic Model with ExtJS 4 but in 5th version there is no method setFields for the model.

Answer 1

Thanks for everybody, I used method addFields() and made it in this way:

var model = Ext.ClassManager.get('app.model.GridModel');
var fields = [];
fields.push({ name: 'param', type: 'string' });
for (var i=1; i<20; i++){
   fields.push({ name: 'name', type: 'string'});
}
model.addFields(fields);

Answer 2

使用Ext.data.Model.setConfig（）方法。

Answer 3

There is a replaceFields method , though.

Note that this won't magically create the field data any existing models, though.
