PugJs - 找不到模板文件/目录被忽略

Question

我有一个应该输出小内容的简单应用程序。我使用 NodeJs，Express和Pug 。

const pug = require('pug');
const express = require('express');
const app = express();

const indexFile = 'index'; // the file to load

app.set('view engine', 'pug'); // use pug

app.get('/', function (req, res) {
  res.render(indexFile, { templateToLoad: 'Views/Templates/temp.pug' }); // include a template file
});

app.listen(8888, function () {
  console.log('Server running on port 8888');
});

我的Pug文件/ HTML

doctype html
html
    body
      p default content on all pages
      include templateToLoad

我的目录看起来

启动服务器时收到此错误消息

Error: ENOENT: no such file or directory, open 'C:\Users\mah\Desktop\Test\views\templateToLoad.pug'
    at C:\Users\mah\Desktop\Test\views\index.pug line 5

    at walkAST (C:\Users\mah\Desktop\Test\node_modules\pug-walk\index.js:37:19)

但在调试templateToLoad时，我得到'Views/Templates/temp.pug'。为什么文件夹Templates会被忽略？

Answer 1

有些挖掘 - 似乎帕格不支持动态包含（你试图在这里做）

https://github.com/pugjs/pug/issues/569

可能的解决方法包括使用jade.render或重复使用res.render来生成模板。

• use-a-variable-in-a-jade-include

Answer 2

动态包含在哈巴狗中not supported。 我建议您发送模板名称并在index.pug中使用conditionals来显示所需的模板。

注意：您需要在temp1文件夹中存在temp2，tempN ... Templates

doctype html
html
    body
      p default content on all pages
      if templateToLoad == "temp1"
        include Templates/temp
      else if templateToLoad == "temp2"
        include Templates/temp2

发送模板名称。

app.get('/', function (req, res) {
  res.render(indexFile, { templateToLoad: 'temp1' }); // include a template file
});

Pug建议模板继承https://pugjs.org/language/inheritance.html

因此，您无需渲染index.pug，而是渲染模板：

index.pug：

doctype html
html
  body
    p default content on all pages
    block content

temp.pug：

extends index.pug
block content
  p My template

your server.js

app.get('/', function (req, res) {
  res.render('temp');
});
