Odoo v12 javascript 双rpc调用问题

Question

I have created the class crm.dashboard.py have 2 methods, I want to call them in JS, the first controller works but when I call the second I get this error:

AttributeError: type object 'crm.dashboard' has no attribute 'get_test_info'  

Any solution please?

init: function(parent, context) {
    this._super(parent, context);
    var crm_data = [];
    var test_data = [];

    var self = this;
    if (context.tag == 'crm_dashboard.dashboard') {
        self._rpc({
            model: 'crm.dashboard',
            method: 'get_crm_info',
        }, []).then(function(result){
            self.crm_data = result[0]
        })

        self._rpc({
            model: 'crm.dashboard',
            method: 'get_test_info',
        }, []).then(function(result){
            self.test_data = result[0]
        })


        .done(function(){
            self.render();
            self.href = window.location.href;
        });


    }
}

Code of the method:

@api.model
def get_test_info(self):

    expected_revenue = 0
    obj_test = self.env['sale.order'].sudo().search([])
    amount_total = 0
    for sale in obj_test:
        amount_total = round(amount_total + (sale.amount_untaxed + sale.amount_tax))
    test_details = [{}]
    if test_details:
        data = {
            'amount_total': amount_total,

        }

        test_details[0].update(data)

        print("TEST________________", test_details)
    return test_details

The message says "I don't find the method get_test_info in model crm.dashboard".

The problem isn't your JS but "your" python file.

Possible error:

• The python file with model 'crm.dashboard' and method 'get_test_info' isn't import in __init__.py
• The folder models isn't import in your __init__.py of your module.
• Missing depends (implied not installed)
• The method name is different.
