使用FormView类中的POST数据查询数据库

Question

我对Django很新，需要帮助完成一项简单的任务。我有两个模板。

1. search.html：呈现一个包含文本字段，提交按钮和POST /search_results/
的简单表单
2. search_results.html：需要将数据库查询的结果呈现为/search_results/

在我的forms.py文件中：

from django import forms

class SystemsForm(forms.Form):
    serial_num = form.CharField(label="Serial no.", max_length=45)

在我的urls.py中

urlpatterns = patterns('',
                       url(r'^search/$', SystemSearch.as_view()),
                       url(r'^search_results/$', SystemResult.as_view()),
                       )

在我的views.py文件中

from django.views.generic.edit import FormView
from inventory.forms import SystemsForm

class SystemSearch(FormView):
    # For displaying the form
    template_name = 'inventory/search.html'
    form_class = SystemsForm

class SystemResult(FormView):
    template_name = 'inventory/search_result.html'
    form_class = SystemsForm
     # How to do these two things?
     # Query the database model called Systems with the POST data
     #     -- Systems.objects.get(serial_num=??)
     # pass context to search_result.html

我甚至不确定我是朝着正确的方向前进，还是完全偏离了我应该做的事情。
