当我想在 Django 中实现搜索功能时的一些错误

Question

这是我的models.py（模型是由 django 从 MySQL 数据库中提取的）：

from __future__ import unicode_literals

from django.db import models

这是我的views.py（我在这里写了搜索功能）

from django.shortcuts import render
from dict.models import Cyshici

def index(request):
    Cyshici_list = Cyshici.objects.all()
    context_dict = {'cyshici': Cyshici_list}
    return render(request, 'dict/base.html', context_dict)

def search(request):

    result_cyshici_list = []

    if request.method == 'GET':
        if 'field_1' in request.GET:
            field_1 = request.GET['field_1']
            try:
                words = Cyshici.objects.filter(field_1=field_1)
                result_cyshici_list.append(words)
            except:
                pass

    return render(request, 'dict/search.html', {'result_cyshici_list': result_cyshici_list})

搜索.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf8">
</head>
<body>

{{ result_cyshi_list }}

</body>
</html>

这是我的 base.html。我希望它显示搜索表单。

<!DOCTYPE html>
<html lang="en">
<head> 
    <meta charset="utf8">
</head>
<body>

    <form method="get" action="/dict/search/" enctype="mutipart/form-data">
    <div class="form-group">
         <p><input class="form-control" id="search_cyshici" name="cyshici" /></p>
    </div>
</form>

</body>
</html>

HTML 正在返回一个空白页面。谁能帮助我了解问题所在或指出正确的方向？

Answer 1

您的表单只有一个名为“cyshici”的输入，因此这是您在 request.GET 中获得的唯一键。 尝试将输入的名称更改为“field_1”，或更改您的视图代码以在 request.GET 中查找“cyshici”键。
