擴大我的搜索功能

Question

我正在試圖擴大我的小型項目的搜索功能。現在我有能力使用char字段進行搜索，但我想添加一些複選框。有些項目已被SRED複選框標記，我也希望能夠搜索僅SRED的項目。

這是我目前的搜索設置。

models.py

class Project(models.Model): 
...  
proj_name = models.CharField(max_length=255, verbose_name='Project Name') 
pre_quote = models.CharField(max_length=3) 
quote = models.IntegerField(max_length=10, verbose_name='Quote #', unique=True) 
... 
SRED = models.BooleanField() 
... 

Views.py

@login_required 
def search(request): 
if request.method == 'POST': 
    form = SearchProjectForm(request.POST) 
    if not form.is_valid(): 
     return render_to_response('project/search.html', {'form': form}, context_instance=RequestContext(request)) 
    else: 
     projects = Project.objects.filter(proj_name__icontains = form.cleaned_data["text"]) 
     companies = Clients.objects.filter(client_name__icontains = form.cleaned_data["text"]) 
     return render_to_response('project/search.html', {'form': form, 'projects':projects, 'companies': companies}, context_instance=RequestContext(request)) 

form = SearchProjectForm() 

return render_to_response('project/search.html', {'form': form}, context_instance=RequestContext(request)) 

forms.py

class SearchProjectForm(forms.Form): 
    text = forms.CharField(label = "Search") 

search.html

<form method="POST" action=""> 
{% csrf_token %} 
{{form}} 
<input type="submit" value="Search"/> 
</form> 
<h3>Search Results</h3> 
... 

任何幫助將不勝感激！

再次感謝

您需要將項目表單構造，然後添加盒領域，如果必要的：

form = SearchProjectForm(project, request.POST) 

和：

class SearchProjectForm(forms.Form): 
    text = forms.CharField(label = "Search") 

    def __init__(self, project, *args, **kwargs): 
     form = forms.Form.__init__(self, *args, **kwargs) 
     if project.has_additional_fields(): 
     self.fields['additional_field'] = forms.SomeField() 
     if project.only_additional_fields(): 
     self.fields['text'].required = False
