AngularJS控制器代码:
function AuthConfig($stateProvider, $httpProvider) {
'ngInject';
// Define the routes
$stateProvider
.state('app.login', {
url: '/login',
templateUrl: 'auth/auth.html',
title: 'Sign in'
})
.state('app.register', {
url: '/register',
templateUrl: 'auth/auth.html',
title: 'Sign up'
});
};
export default AuthConfig;
我无法弄清楚ngInject的用途.有人可以帮帮我吗？
我使用lambda跟随函数用NaN替换了缺少的值:
data = data.applymap(lambda x: np.nan if isinstance(x, basestring) and x.isspace() else x)
,数据是我正在处理的数据帧.
之后使用seaborn,我尝试绘制其中一个属性,使用seaborn.distplot进行alcconsumption,如下所示:
seaborn.distplot(data['alcconsumption'],hist=True,bins=100)
plt.xlabel('AlcoholConsumption')
plt.ylabel('Frequency(normalized 0->1)')
它给了我以下错误:
AttributeError: max must be larger than min in range parameter.
我有一个简单的node.js代码,它使用mongoose,它在保存但无法检索时有效.
.save()有效,但.findOne()没有.
mongoose = require('mongoose');
mongoose.connect("mongodb://localhost/TestMongoose");
UserSchema = new mongoose.Schema({
field: String
});
Users = mongoose.model('userauths', UserSchema);
user = new Users({
field: 'value'
});
//user.save();
^工作.即用值更新数据库.截图
//user.findOne({field:'value'},function(err,value){});
^引发错误:
user.findOne({field:'value'},function(err,value){});
^
TypeError: Object { field: 'value', _id: 52cd521ea34280f812000001 } has no method 'findOne'

console.log(JSON.stringify( user , null, 40));
^只返回对象 {field: 'value'}
console.log(JSON.stringify( Users , …我的数据框df中有以下列:
df.dtypes
MeanTemperatureC int64
MaxTemperatureC float64
MinTemperatureC int64
DewPointC int64
MeanDewPointC int64
MinDewpointC int64
MaxHumidity int64
MeanHumidity int64

MaxVisibilityKm int64
MeanVisibilityKm float64
MinVisibilitykM float64
MaxWindSpeedKm/h int64
MeanWindSpeedKm/h int64
MeanTemperatureCT category
dtype: object
我想将列'MeanTemperatureCT'的数据类型更改为str.我已经尝试过以下方法:
df['MeanTemperatureCT'].astype(np.str)
并没有改变数据类型.所以,请帮忙.
以下是我需要创建的不同类的设置:
Author – AuthorId, AuthorName, DateOfBirth, State, City, Phone.
Publisher – PublisherId, PublisherName, DateOfBirth, State, City, Phone.
Category – CategoryId, CategoryName, Description.
Book – BookId, Category, Title, Author, Publisher, Description, Price, ISBN, PublicationDate.
现在您可以看到Book中的Author和Author类中的AuthorId是相同的.如何在C#中实现这一点
