Django - 基於來自搜索視圖的搜索查詢呈現視圖

我有什麼可能是一個非常基本的問題。我已閱讀Django forms docs，但我仍然在這裏失蹤。我想在一個模板中有一個搜索欄（search.html），並在另一個模板（results.html）中返回搜索查詢。到目前爲止，我使用了this SO answer as a guide，它返回以下錯誤。謝謝你的幫助。Django - 基於來自搜索視圖的搜索查詢呈現視圖

Exception Value:  
results() missing 1 required positional argument: 'search_id'

urls.py

urlpatterns = [ 
    url(r'^$', views.index, name='index'), 
    url(r'^landing/', views.search, name='search'), 
    url(r'^results/', views.results, name='results'), 
]

forms.py

from .models import Apartment 
class Apt(forms.ModelForm): 
    class Meta: 
     model = Apartment 
     fields = ('name')

views.py

def search(request): 
    if request.method == 'POST': #the form has been submitted 
     form = Apt(request.POST) #bound form 
     if form.is_valid(): #validations have passed 
      name = form.cleaned_data['name'] 
      u = Apt.objects.create(name=name) 
      #REST query will go here. 

      #commit to database 
      u.save() 

      return redirect('results', search_id=u.name) 

    else: #create an unbound instance of the form 
     form = Apt(initial={'name':'name'}) 
    #render the form according to the template, context = form 
    return render(request, 'search/landing.html', {'form':form}) 

def results(request, search_id): 
    search_id = request.POST.get('name') 
    query = get_object_or_404(Apt, pk=search_id) 
    return render(request, 'search/results.html', {'query':query})

URL中您需要更改結果

url(r'^results/(?P<search_id>.+)/', views.results, name='results'),

在正則表達式

命名組作爲傳遞參數

您還應該從結果視圖中刪除行search_id = request.POST.get('name')，因爲重定向不會包含任何POST數據

謝謝。我更改了url並刪除了search_id，但現在出現錯誤：異常值：\t 未找到參數'（）'和關鍵字參數'{}'的'結果'反轉。 1個模式嘗試：['results /（？P 。+）/']'當我去登陸的網址 – Jebediah15

您是否使用url標記中的「結果」視圖？或在另一個反向？ –

您應該從登陸模板中移除'action =「{％url'results'％}」''。您正在處理搜索視圖中的表單驗證 –
