Question

我对Django比较新。我想从填充表单中保存数据，这是填充到timesheet.html中的数据到数据库然后检索数据并将其显示到list_timetable.html的表中。但是我被困住了，并且会在views.py＆＃34; query_results = ltimesheet.objects.all（）＆＃34;上获得属性错误。

timesheet.html

{% extends 'hrfinance/base.html' %}
{% block title %} Timesheet {% endblock %}
{% block link %}
{% load staticfiles %}
<link rel="stylesheet" href="{% static 'hrfinance/css/timesheet.css' %}"/>
 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script>
    /*to ensure that all the textbox and checkbox have been filled before users can submit*/
    function validation() {
        /*ensure start date has been entered*/
        if (!$('#sdate').val().trim()) {
            alert('Please fill in start date field');
        }
        /*ensure end date has been entered*/
        if (!$('#edate').val().trim()) {
            alert('Please fill in end date field');
        }
        /*ensure checkbox has been ticked*/
        if (!$('#agree').is(':checked')) {
            alert('Please indicate that you have satisfied all the requirements');
        }
        else{
            console.log('ok')
      }
    }
</script>
{% endblock %}
{% block body %}
<div class="sub-bar">
    <p>Submit Timesheet</p>
</div>
<br>
<br>
<br>
<br>
<br>
<br>
<form onsubmit="return validation()">
    <div class="content-wrapper">
        <div class="sub-content">
            <div>
                <p>Start Date: {{timesheet.startDate}}</p>
                <input id="sdate" type="date" name="startdate">
            </div>
        </div>

        <div class="sub-content">
            <div>
                <p>End Date: {{timesheet.endDate}}</p>
                <input id="edate" type="date" name="enddate">
            </div>
        </div>
    </div>
    <br>
    <br>
    <br>
    <br>
    <br>
    <br>
    <br>
    <br>
    <br>
    <div class="end-content">
        <div class="center-align">
            <div class="checklist">
                <p>By checking this box I agree that I have satisfied all requirements to continue receiving my scholarship
            allowance.</p>
                <input id="agree" type="checkbox" name="checkbox" class="tick-att">
            </div>

list_timesheet.html - 用于显示表格中的数据

{% block body %}
<table>
    <tr>
        <th>Student ID</th>
        <th>Student Name</th>
        <th>Start Date</th>
        <th>End Date</th>
        <th>Status</th>
    </tr>
    { % for item in query_results % }
    <tr>
        <td>{{ltimesheet.timesheet}}</td>
        <td>{{ltimesheet.status}}</td>
    </tr>
    { % end for % }
</table>
<table id="example" class="display" cellspacing="0" width="100%">
{% endblock %}

views.py

from django.shortcuts import render
from django.http import HttpResponse
from .models import Timesheet, LTimesheet, Application, Scholarship

def ltimesheet(request):
query_results = ltimesheet.objects.all()
return render(request, 'hrfinance/list_timesheet.html')

models.py

from django.db import models

from django.http import HttpResponseRedirect
from django.shortcuts import render

#consists of all the details in the timesheet
class Timesheet(models.Model):
studentID = models.CharField("Student ID", max_length=8, primary_key=True, default="")
studentName = models.CharField("Student Name", max_length=500, default="")
startDate = models.DateField("Start Date", max_length=8)
endDate = models.DateField("End Date", max_length=8)

def __str__(self):
    return self.studentID

#consists of all the details of the timesheet under 'View Timesheets'        

class LTimesheet(models.Model):
timesheet = models.ForeignKey(Timesheet, on_delete=models.CASCADE)
status = models.CharField("Status", max_length=100)

Answer 1

这是因为python是区分大小写的，你使用的是函数名（ltimesheet）而不是模型名（LTimesheet），还有渲染数据，你需要将它们传递给你的html文件

将views.py文件更改为：

from django.shortcuts import render
from django.http import HttpResponse
from .models import Timesheet, LTimesheet, Application, Scholarship

def ltimesheet(request):
    query_results = LTimesheet.objects.all()
    data={query_results:query_results}
    return render(request, 'hrfinance/list_timesheet.html',data)

从填充表单中检索数据然后保存到数据库中，然后以表格形式显示DJANGO
