我是django新手，很难通过“get”方法从模型数据库表中获取结果

我的型号是：

class records(models.Model): sex = (('M', 'MALE'),('F', 'FEMALE'),) reg_number = models.CharField(max_length=15) mic_number = models.CharField(max_length=15) dog_name = models.CharField(max_length=20) dog_breed = models.CharField(max_length=50) color = models.CharField(max_length=20) dog_Sex = models.CharField(max_length=1,choices=sex) Breeder = models.CharField(max_length=30) Owner_name = models.CharField(max_length=50) address = models.TextField(max_length=264)

from django.shortcuts import render import datetime from .forms import RecordForm from .models import records # Create your views here. def index (request): return render(request, "newyear/index.html") def search (request): mic = request.GET['mic'] r = records.objects.filter(mic_number__iexact = mic ) return render(request,"newyear/search.html", {"records": r})
我的视图是：

class records(models.Model): sex = (('M', 'MALE'),('F', 'FEMALE'),) reg_number = models.CharField(max_length=15) mic_number = models.CharField(max_length=15) dog_name = models.CharField(max_length=20) dog_breed = models.CharField(max_length=50) color = models.CharField(max_length=20) dog_Sex = models.CharField(max_length=1,choices=sex) Breeder = models.CharField(max_length=30) Owner_name = models.CharField(max_length=50) address = models.TextField(max_length=264)

from django.shortcuts import render import datetime from .forms import RecordForm from .models import records # Create your views here. def index (request): return render(request, "newyear/index.html") def search (request): mic = request.GET['mic'] r = records.objects.filter(mic_number__iexact = mic ) return render(request,"newyear/search.html", {"records": r})
我的索引模板是：

<form action="{% url 'search'%}" enctype="application/x-www-form-urlencoded" method="GET"> <ul><input type="text" name = "mic"></ul> <button type="submit" name= "search">search</button> </form>

<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Document</title> </head> <body> <h1>THIS IS RESULT PAGE</h1> {% if records %} <table> {% for records in records %} <tr> <td>{{records.color}}</td> <td>{{records.dog_name}}</td> <td>{{records.mic_number}}</td> </tr> {% endfor %} </table> {% endif %} </body> </html>

搜索
我的搜索模板是：

<form action="{% url 'search'%}" enctype="application/x-www-form-urlencoded" method="GET"> <ul><input type="text" name = "mic"></ul> <button type="submit" name= "search">search</button> </form>

<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Document</title> </head> <body> <h1>THIS IS RESULT PAGE</h1> {% if records %} <table> {% for records in records %} <tr> <td>{{records.color}}</td> <td>{{records.dog_name}}</td> <td>{{records.mic_number}}</td> </tr> {% endfor %} </table> {% endif %} </body> </html>

文件这是结果页面 {%if记录%} {记录%中的记录为%s} {{records.color} {{records.dog_name} {{records.mic_number} {%endfor%} {%endif%}

search.html
仅显示“这是结果页”。以上方法有什么错误，请帮助。我已经挣扎了3天。
循环变量（
记录
）与循环详细信息（
记录
）相同。因此，请将
记录
更改为
记录
，如下所示。并将
GET
方法更改为
POST

<h1>THIS IS RESULT PAGE</h1> {% if records %} <table> {% for record in records %} <tr> <td>{{record.color}}</td> <td>{{record.dog_name}}</td> <td>{{record.mic_number}}</td> </tr> {% endfor %} </table> {% endif %}
index.html

<form action="{% url 'search'%}" enctype="application/x-www-form-urlencoded" method="POST"> <ul><input type="text" name = "mic"></ul> <input type="submit" value="search" name= "search"> </form>

Search.html仅显示“这是结果页”。以上方法有什么错误，请帮助。3天来我一直在努力。我试过了，但仍然没有显示任何记录。页面保持空白。检查
记录这是空的？？通过将{{records}} 添加到template.no，当我删除所有内容并发送查询记录.objects.all（）时，记录不是空的。如果我手动输入mic_编号并删除mic，它也会显示结果。问题是它没有从表单中获取参数。mic\u number 数据库值中必须手动输入（index url），然后显示详细信息。我认为这个错误是你的错误。我用正确的答案在本地运行它。是的，它起作用了，非常感谢。我松了一口气。
