为什么我的快速应用程序中的导航栏上没有其他选项卡？(Why won't other tabs on my navbar apear in my express app?)

 我正在尝试使用express和charlotte构建一个应用程序。 我正在使用ejs来渲染我的html文件。 我有一个针对css的twitter bootstrap。 出于某种原因：  
<div class="navbar navbar-fixed-top">
  <div class="navbar-inner">
    <div class="container">
      <a class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse">
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
      </a>
      <a class="brand" href="#"><img src="./img/MySpending.png"></a>
      <div class="nav-collapse">
        <ul class="nav">
      <li ><a href="./login.html">Log in/out</a></li>
          <li class="active"><a href="#">Daily</a></li>
      <li ><a href="./monthly.html">Monthly</a></li>
          <li ><a href="./yearly.html">Yearly</a></li>
        </ul>
      </div><!--/.nav-collapse -->
  <div class='navbar_form pull-right'>

      </div>
    </div>
  </div>
 
 
 对我来说，好像我的html不会在快递中更新。  
 这是我的app.js快递如果有帮助：  
var express = require('express');

var conf = require('./conf');

var everyauth = require('everyauth')
  , Promise = everyauth.Promise;

everyauth.debug = true;

var mongoose = require('mongoose')
  , Schema = mongoose.Schema
  , ObjectId = mongoose.SchemaTypes.ObjectId;

var UserSchema = new Schema({})
  , User;

var mongooseAuth = require('mongoose-auth');

var path = require('path');

UserSchema.plugin(mongooseAuth, {
    everymodule: {
      everyauth: {
          User: function () {
             return User;
          }
      }
    }
   , password: {
        loginWith: 'email'
        , extraParams: {
             phone: String
           , name: {
                first: String
               , last: String
             }
         }
      , everyauth: {
             getLoginPath: '/login'
          , postLoginPath: '/login'
          , loginView: 'login.jade'
          , getRegisterPath: '/register'
          , postRegisterPath: '/register'
          , registerView: 'register.jade'
          , loginSuccessRedirect: '/'
          , registerSuccessRedirect: '/'
        }
     }
   , google: {
       everyauth: {
           myHostname: 'http://localhost:3000'
         , appId: conf.google.clientId
         , appSecret: conf.google.clientSecret
         , redirectPath: '/'
         , scope: 'https://www.google.com/m8/feeds'
      }
    }
});
// Adds login: String

mongoose.model('User', UserSchema);

mongoose.connect('mongodb://localhost/mydb');

User = mongoose.model('User');

var app = express();/*express.createServer(
    express.bodyParser()
  , express.static(__dirname + "/public")
  , express.cookieParser()
  , express.session({ secret: 'esoognom'})
  , mongooseAuth.middleware()
);*/

app.configure( function () {
   app.set('views', __dirname + '/views');
   app.set('view engine', 'ejs');
   app.engine('html', require('ejs').renderFile);
   app.use(express.static(path.join(__dirname, 'public')));
});


app.get('/', function (req, res) {
   res.render('index.html');
});
app.get('/monthly', function (req, res) {
   res.render('monthly.html');
});
app.get('/yearly', function (req, res) {
   res.render('yearly.html');
});

/*app.get('/logout', function (req, res) {
     req.logout();
    res.redirect('/');
});*/

mongooseAuth.helpExpress(app);

app.listen(3000);
 
 所以我不确定是什么让视图不再更新，因为它目前正在渲染旧版本，导航中只有一个选项卡。 任何有关这方面的帮助将不胜感激。 

I'm trying to build an app using express and charlotte. I'm using ejs to render my html files. I have a twitter bootstrap for the css. For some reason this: 
<div class="navbar navbar-fixed-top">
  <div class="navbar-inner">
    <div class="container">
      <a class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse">
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
      </a>
      <a class="brand" href="#"><img src="./img/MySpending.png"></a>
      <div class="nav-collapse">
        <ul class="nav">
      <li ><a href="./login.html">Log in/out</a></li>
          <li class="active"><a href="#">Daily</a></li>
      <li ><a href="./monthly.html">Monthly</a></li>
          <li ><a href="./yearly.html">Yearly</a></li>
        </ul>
      </div><!--/.nav-collapse -->
  <div class='navbar_form pull-right'>

      </div>
    </div>
  </div>
 
 
To me it seems like my html won't update in express. 
here's my app.js in express if that helps: 
var express = require('express');

var conf = require('./conf');

var everyauth = require('everyauth')
  , Promise = everyauth.Promise;

everyauth.debug = true;

var mongoose = require('mongoose')
  , Schema = mongoose.Schema
  , ObjectId = mongoose.SchemaTypes.ObjectId;

var UserSchema = new Schema({})
  , User;

var mongooseAuth = require('mongoose-auth');

var path = require('path');

UserSchema.plugin(mongooseAuth, {
    everymodule: {
      everyauth: {
          User: function () {
             return User;
          }
      }
    }
   , password: {
        loginWith: 'email'
        , extraParams: {
             phone: String
           , name: {
                first: String
               , last: String
             }
         }
      , everyauth: {
             getLoginPath: '/login'
          , postLoginPath: '/login'
          , loginView: 'login.jade'
          , getRegisterPath: '/register'
          , postRegisterPath: '/register'
          , registerView: 'register.jade'
          , loginSuccessRedirect: '/'
          , registerSuccessRedirect: '/'
        }
     }
   , google: {
       everyauth: {
           myHostname: 'http://localhost:3000'
         , appId: conf.google.clientId
         , appSecret: conf.google.clientSecret
         , redirectPath: '/'
         , scope: 'https://www.google.com/m8/feeds'
      }
    }
});
// Adds login: String

mongoose.model('User', UserSchema);

mongoose.connect('mongodb://localhost/mydb');

User = mongoose.model('User');

var app = express();/*express.createServer(
    express.bodyParser()
  , express.static(__dirname + "/public")
  , express.cookieParser()
  , express.session({ secret: 'esoognom'})
  , mongooseAuth.middleware()
);*/

app.configure( function () {
   app.set('views', __dirname + '/views');
   app.set('view engine', 'ejs');
   app.engine('html', require('ejs').renderFile);
   app.use(express.static(path.join(__dirname, 'public')));
});


app.get('/', function (req, res) {
   res.render('index.html');
});
app.get('/monthly', function (req, res) {
   res.render('monthly.html');
});
app.get('/yearly', function (req, res) {
   res.render('yearly.html');
});

/*app.get('/logout', function (req, res) {
     req.logout();
    res.redirect('/');
});*/

mongooseAuth.helpExpress(app);

app.listen(3000);
 
So I'm not sure what's keeping the view from updating, because it currently is rendering an older version with only one tab in the nav. Any help with this would be greatly appreciated.

最满意答案

 试试这段代码：  
import matplotlib.pyplot as pl
import numpy as np

x = np.linspace(1, 10)

def f(x):
    return np.sin(x) + np.random.normal(scale=0.1, size=len(x))

pl.plot(x, f(x))
 
 它会给你一个带有一些噪音的正弦波：  
 
 编辑：  
 似乎某种随机游走是您正在寻找的。 这个功能会为你做到这一点：  
def f(x):
    y = 0
    result = []
    for _ in x:
        result.append(y)
        y += np.random.normal(scale=1)
    return np.array(result)
 
 这是它的外观示例（ x = np.linspace(0, 1000, 1000) ）：  
 
 它不再是x的函数，因此代码应该被重构以生成带有n步骤的随机游走。 我会把它留给你:)  
 编辑2：  
 如果你想要一个更平滑的曲线，你可以应用一个运行平均值（ 从这个问题中偷来 ）：  
def runningMean(x, N):
    return np.convolve(x, np.ones((N,))/N)[(N-1):]

pl.plot(x, runningMean(f(x), 10))
 
 您使用的窗口越大（ N参数），结果越平滑。  
 例：  

Try this code: 
import matplotlib.pyplot as pl
import numpy as np

x = np.linspace(1, 10)

def f(x):
    return np.sin(x) + np.random.normal(scale=0.1, size=len(x))

pl.plot(x, f(x))
 
It will give you a sin wave with some noise added to it: 
 
Edit: 
It seems like some kind of random walk is what you're looking for. This function will do that for you: 
def f(x):
    y = 0
    result = []
    for _ in x:
        result.append(y)
        y += np.random.normal(scale=1)
    return np.array(result)
 
This is an example of what it can look like (with x = np.linspace(0, 1000, 1000)): 
 
It's not a function of x any longer though, so the code should probably be refactored to generate a random walk with n steps instead. I'll leave that to you :) 
Edit 2: 
If you want a smoother curve, you can apply a running mean (stolen from this question): 
def runningMean(x, N):
    return np.convolve(x, np.ones((N,))/N)[(N-1):]

pl.plot(x, runningMean(f(x), 10))
 
The bigger window (the N parameter) you use, the smoother the result. 
Example:
