Odoo IndexError:列表分配索引超出范围 [英] Odoo IndexError: list assignment index out of range

问题描述

我只是创建一个模块.添加值后出现问题IndexError:列表分配索引超出范围.如何解决.请重新编辑代码. 这是我的代码:

I just create a module. After adding values and got the problem IndexError: list assignment index out of range. How to fix it. Re Edit code please. Here is my code:

class calculator(osv.osv):
    _name = 'calculator.calculator'
    def get_total(self, cr, uid, ids, field_name, arg, context):
            res = []
            perfos = self.browse(cr, uid, ids, context)
            for perfo in perfos:
                res[perfo.id] = perfo.p + perfo.b
            return res
    _columns = {
        'p':fields.selection(((1,'Outstanding'), (2,'Well Above Expectations'), (3,'As Expected'), (4,'Below Expectations'), (5,'VeryPoor'), (0,'N/A')),'title'),
        'b':fields.selection(((1,'Outstanding'), (2,'Well Above Expectations'), (3,'As Expected'), (4,'Below Expectations'), (5,'Very Poor'), (0,'N/A')),'title'),
        'total' : fields.function(get_total, method=True, string='Total Mark'),
    }

推荐答案

您需要返回功能字段字典的字典.您将res定义为列表，并尝试指定为字典. res[perfo.id]被视为列表，而在res列表中找不到索引值perfo.id.那就是错误的意思.现在的代码将是

You need to return a dictionary of dictionary for functional fields. You defined res as list and tried to assign as the dictionary. res[perfo.id] is considered as list and index value perfo.id is not found in the res list. That is what the error says. Now the code will be

class calculator(osv.osv):
    _name = 'calculator.calculator'

    def get_total(self, cr, uid, ids, field_name, arg, context):
        res = {}
        for perfos in self.browse(cr, uid, ids, context):
            res[perfos.id] = perfos.p + perfos.b
        return res

    _columns = {
        'p':fields.selection(((1,'Outstanding'), (2,'Well Above Expectations'), (3,'As Expected'), (4,'Below Expectations'), (5,'VeryPoor'), (0,'N/A')),'title'),
        'b':fields.selection(((1,'Outstanding'), (2,'Well Above Expectations'), (3,'As Expected'), (4,'Below Expectations'), (5,'Very Poor'), (0,'N/A')),'title'),
        'total' : fields.function(get_total, method=True, string='Total Mark'),
    }

对于上面的代码，您可能会遇到此js错误Error: [_.sprintf] expecting number but found string

For the above code you probably get this js error Error: [_.sprintf] expecting number but found string

我不明白加起来两个选择字段的意义.密钥将以unicode格式加起来像1 + 1.

I don't get the point adding up two selection fields. The key will get added up like 1+1 in a unicode format.

下面的代码将为您提供功能字段的基本概念.

This following code will give you the basic idea of functional fields.

class calculator(osv.osv):
    _name = 'calculator.calculator'

    def get_total(self, cr, uid, ids, field_name, arg, context):
        res = {}
        for perfos in self.browse(cr, uid, ids, context):
            res[perfos.id] = perfos.p + perfos.b
        return res

    _columns = {
        'p':fields.integer('A'),
        'b':fields.integer('B'),
        'total' : fields.function(get_total, method=True, string='Total Mark'),
        }
