我有一个客户表单,它将数据保存到包含名字、姓氏、电话、电子邮件、地址等的表格列表中。我在列表上有一个排序功能,当单击标题时,它会从 AZ 或 ZA 对该字段进行排序。问题是,我有一个地址字段,它是来自不同模型的外键 - 它不按字母顺序排序,而是使用各自的主键(pk)进行排序。
Address 模型包含 Address、City、County、Postcode 和 Country,并以下列方式返回到表列表:“Street Name, City, COUNTY, Country。”
排序功能在我的 template.mako 中:
<thead>
<tr>
<%
# a list of column field names and labels
column_fields = (
('first_name', 'First Name'),
('surname', 'Last Name'), ,
('phone__number', 'Phone'),
('email__email', 'Email'),
('address', 'Address'),
)
columns = ( {'field':x[0], 'label':x[1]} for x in column_fields )
%>
% for column in columns:
% if column['field'] == sort_field:
<th><a href="${self.util.reverse('customers')}?sort=- ${column['field']}">${column['label']}</th>
% else:
<th><a href="${self.util.reverse('customers')}?sort=${column['field']}">${column['label']}</th>
% endif
% endfor
</tr>
</thead>
Email 和 Phone 也是外键,但每个只有一个字段来获取它们的模型(email_email和phone_number)。
将始终选择一个县,因为它是一个下拉列表并且具有默认值。因此,如果未提交地址/城市字段,我希望能够按县排序。而如果地址/城市字段已填写,我想按它们排序。
知道如何让地址排序
我的意见.py:
def customers(request):
filtered = False
sort_field = request.GET.get('sort', 'first_name')
our_customers = Customer.objects.order_by(sort_field)
form = SearchForm(request.POST or None, request.FILES or None)
if request.method == 'POST' and \
form.is_valid() and \
form.cleaned_data['search'] and \
'clear-searchform' not in request.POST:
search = form.cleaned_data['search']
search_list = search.split()
duplicated_customers = []
for item in search_list:
the_customers = Customer.objects.filter(
Q(slug__icontains=item) |
Q(first_name__icontains=item) |
Q(surname__icontains=item) |
Q(dob__icontains=item) |
Q(phone__number__icontains=item) |
Q(email__email__icontains=item) |
Q(address__address__icontains=item) |
Q(address__city__icontains=item) |
Q(address__county__icontains=item) |
Q(address__postcode__icontains=item) |
Q(address__country__icontains=item) |
Q(medical__icontains=item) |
Q(notes__icontains=item)
# need to amend so can search by organization
)
duplicated_customers = chain(duplicated_customers, the_customers)
filtered = True
our_customers = set(duplicated_customers)
elif 'clear-searchform' in request.POST:
form = SearchForm()
dictionary = dict(
form=form,
customers=our_customers,
sort_field=sort_field,
filtered=filtered,
display_name=_('Customers'),
)
return dictionary
“Q()”用于列表中设置的搜索功能。
