Question

我是Python / Django的新手并尝试创建搜索框，该搜索框从API中获取数据并在HTML上返回结果。就像任何其他搜索引擎一样。

我必须通过标头传递令牌。这是我目前的代码。

url.py

from django import forms

class SearchForm(forms.form):
search_company = forms.CharField(label='search_company',max_length=100)

form.py

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

def get_search (request):
    if request.method == 'POST':
        form = SearchForm(request.POST)

        if form.is_valid():
            return HttpResponseRedirect('/search.html')
        else:
            form = SearchForm()

        return render(request, "main/search.html")

views.py

  <form class="col-md-6" action="/search.html/" method="post">
      {% csrf_token %}
      <label for="search_company">Search Company</label>
      <input type="text" name="search_company">
      <input type="submit" value="ok">
  </form>

search.html

这是我在控制台中的错误

<customErrors mode="On">
      <error statusCode="404" redirect="~/Home/Error404" />
    </customErrors>

修改：更新了新错误。

Answer 1

来自django import SearchForm
ImportError：无法导入名称＆＃39; SearchForm＆＃39;

更新的错误是因为您尝试从django库的根目录导入SearchFrom。

您需要从应用中导入SearchForm，所以在views.py

中

from django import SearchForm

应该是

from myapp.form import SearchForm

此外，在Django中，通常调用包含文件forms（复数）而不是form（单数）的表单，因为它可以包含多个表单。

Answer 2

SearchForm位于您的django应用程序中，而不是您的django库中。

使用.form导入SearchForm

另外，将你的其他人移动到（如果是request.method == POST），这样如果方法没有发布，则发送表单。

我建议你使用reverse（）函数来解析url，

HttpResponseRedirect（反向（ '搜索'））

将表单输入数据传递给post请求
