如何使用express.js，mongoose和jade创建帖子请求

Question

The below code is from a tutorial I'm doing. I want to know how to capture and respond to post requests. I thought this would be easy to understand but the problem is as follows.

First here is the code:

Node

app.post('/tasks', function(req, res){
  var task = new Task(req.body.task);   // This line 
  task.save(function (err) {
    if (!err) {
      res.redirect('/tasks/new');
    }
    else {
      throw err;
    }
  });
});

Jade

extends ../layout

block content
  h1 New task view

  form(role='form', method='post', action='/tasks')
    fieldset
      legend Add a task
      div.form-group
        label Task
        input(name='task[task]', class='form-control')  // This line
      button.btn.btn-primary(type='submit') Submit
      button.btn.btn-default(type='reset') Clear

Mongoose

mongoose.connect('mongodb://localhost/todo_development');
var Schema = mongoose.Schema;
var ObjectId = Schema.ObjectId;

var Task = new Schema({
  task: { type: String, required: true }
});

var Task = mongoose.model('Task', Task);

In the first two blocks of code above each has a comment called 'this line'. Within these lines are the word task as attributes/properties. When I change these to something else like 'oink' it breaks the code.

So for example if I do:

node

  var task = new Task(req.body.oink);   // This line 

jade

input(name='oink[oink]', class='form-control')  // This line

It no worky. I am not sure why nor how to do posts requests correctly. :(

Answer 1

Try changing this line

var task = new Task(req.body.task);

To this:

var task = new Task(req.body);

I'm not very familiar with Jade, but as far as I can tell from Submit Jade form you should name your input like...

input(id='password',type='password',value='',placeholder='',name='password')

Also, what does your mongoose schema look like? That may be helpful.

You have defined the variable "Task" twice. Try this...

var taskSchema = new Schema({
  task: { type: String, required: true }
});

var Task = mongoose.model('Task', taskSchema);

Answer 2

put: input(name='task[]', class='form-control') // This line

and put this: var task = new Task({'task':req.body.task}); // This line
