ActiveJDBC + Backbone.js生成的属性名称不可用

Question

I am using ActiveJDBC to access a third-party db. There is a column named "users/year". I am not happy with that but cannot change it. This results is an attribute "users/year" in the json thats the basis for my backbone.js model. Now if I want to access that attribute in the following template:

<li><%= name+ ' ' + users/year %></li>

Of course it doesn't work. I tried escaping but that doesn't work. Any suggestions?

Since I am new to activeJDBC and backbone.js is there a way off mapping the attribute to a acceptable variable name? Or other possible solutions for that? Should I switch from activeJDBC to something else?

Answer 1

You could add a parse method to your collection or model to remap your attribute to a usable name:

var  M = Backbone.Model.extend({
    parse: function(resp) {
        if (resp['users/year']) {
            resp['users_year'] = resp['users/year'];
            delete resp['users/year'];
        }

        return resp;
    }
});

and change your template accordingly

<li><%= name+ ' ' + users_year %></li>

或者，您也可以使用吸气剂包装器包装模型的动态吸气剂： http : //code.google.com/p/activejdbc/wiki/SettersAndGetters#No_%22standard%22_setters/getters ???
