python - 将值保存到数据库 Django

Question

您好，我是 Django 的新手。我有一个时间表供用户输入详细信息，选择提交按钮时，这些填充字段中的数据将保存到数据库中。但我不知道为什么我的不起作用。由于值将被保存，因此它将被检索并显示在另一个 html 文件的表格中。

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 (!$('#studentid').val().trim()) {
            alert('Please fill in student ID field');
        }
        /*ensure start date has been entered*/
        if (!$('#studentname').val().trim()) {
            alert('Please fill in student name field');
        }
        /*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>

return render(request, 'hrfinance/timesheet.html')

模型.py

#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

正如 Fazil 所说，请查看文档。但首先要给你一点帮助: 您缺少的是 views.py 中的表单验证喜欢:

def timesheet(request):
    user = request.user 
    form = yourform(request.POST or None)
    if form.is_valid():
        ....
        form.save()
    context = {
     'form':form,
     }
  return render(request, 'hrfinance/timesheet.html',context) 

form.save命令将您的表单保存到数据库中。

你的 <form>标签缺少方法! (应该是 POST)。

我建议遵循教程(来自 django 文档或任何其他文档的教程)，以便您了解其工作原理。

一般来说: 你的问题(尤其是代码)越短，就越有可能有人愿意阅读它。像 "<br>" 这样的东西应该剪掉。没有人关心您表单的样式。您的 JS 部分也应该删除，因为它与问题无关。
