[英]NodeJS, Express, Jade POST JSON into DB
I encountered a frustrating problem while following a tutorial based on NodeJS, Express, Jade and MongoDB. 在遵循基于NodeJS,Express,Jade和MongoDB的教程时,我遇到了一个令人沮丧的问题。 This issue has been discussed in other threads on this forum but even following the suggestions already posted, i am unable to get the
POST
command to work. 在此论坛上的其他线程中已经讨论了此问题,但是即使遵循已经发布的建议,我也无法使
POST
命令起作用。
Don't think about the Jade indentation, it might be a little wrong in the copy+paste but correct in the actual code. 不用考虑Jade缩进,在复制粘贴中可能有点错误,但是在实际代码中是正确的。
When i POST
from my input.js page the site throws me a 404 error. 当我
POST
从我input.js网页的网站抛出了我一个404错误。 I know it is not a DB problem because i can output data on other pages just fine. 我知道这不是数据库问题,因为我可以在其他页面上输出数据。
My Jade template for input.js. 我的Jade用于input.js的模板。
extends head
block content
div(id="input_page_wrapper")
div(id="input")
form(id="input_form", name="addEntry", method="post" action="/addEntry")
div(class="label_box")
label(for="restname") Restaurant Name:
input(type="text", placeholder="Example: Soul Kitchen", name="restname")
div(class="label_box")
label(for="restdesc") Restaurant Description:
input(type="text", placeholder="Write a short description.", name="restdesc")
div(class="label_box")
label(for="restdesc") Restaurant Address:
input(type="text", placeholder="Example: Fleminginkatu 26", name="restadd")
button(id="submit", name="submit", type="submit") submit
My input.js Route 我的input.js路线
var express = require('express');
var router = express.Router();
/* GET Input page. */
router.get('/', function(req, res) {
res.render('input', { title: 'Input to Database' });
});
/* POST to Add User Entry */
router.post("/addEntry", function(req, res) {
// Set our internal DB variable
var db = req.db;
// Get our form values. These rely on the "name" attributes
var restName = req.body.restname;
var restDesc = req.body.restdesc;
var restAdd = req.body.restadd;
console.log("post received: %s %s", restName, restDesc, restAdd);
// Set our collection
var collection = db.get('restaurants');
// Submit to the DB
collection.insert({
"name" : restName,
"desc" : restDesc,
"address" : restAdd
}, function (err, doc) {
if (err) {
// If it failed, return error
res.send("There was a problem adding the information to the database.");
}
else {
// And forward to success page
res.redirect("/input");
}
});
});
module.exports = router;

I think you need indent your tags in form, try this, and miss a ',' in form tag (after method="post"): 我认为您需要在表单中缩进标签,然后尝试这样做,并在表单标签中遗漏“,”(在method =“ post”之后):
extends head block content div(id="input_page_wrapper") div(id="input") form(id="input_form", name="addEntry", method="post", action="/input/addEntry") div(class="label_box") label(for="restname") Restaurant Name: input(type="text", placeholder="Example: Soul Kitchen", name="restname") div(class="label_box") label(for="restdesc") Restaurant Description: input(type="text", placeholder="Write a short description.", name="restdesc") div(class="label_box") label(for="restdesc") Restaurant Address: input(type="text", placeholder="Example: Fleminginkatu 26", name="restadd") button(id="submit", name="submit", type="submit") submit
