Я пытаюсь попрактиковаться в некоторых основах Django, реализуя свою собственную сортируемую таблицу в Django, и натолкнулся на пару ошибок.
Вот код, с которым я работаю на мой взгляд:
def __table_view_helper__(request):
if not request.session.__contains__('filters'):
filters = {'filterA':'',
'filterB':'',
'filterC':''}
request.session['filters'] = filters
if not request.session.__contains__('headers'):
headers = {'sortA':'asc',
'sortB':'des',
'sortC':'asc',
'sortD':'asc'}
request.session['headers'] = headers
def table_view(request):
__table_view_helper__(request)
records = Record.objects.all()
nums = list(set(records.values_list('fieldA','fieldA')))
nums.sort()
if request.method == 'POST':
filter = FilterForm(nums,request.POST)
if filter.is_valid():
fieldA = filter.cleaned_data['fieldA']
fieldB = filter.cleaned_data['fieldB']
fieldC = filter.cleaned_data['fieldC']
filters = request.session['filters']
filters['fieldA'] = fieldA
filters['fieldB'] = fieldB
filters['fieldC'] = fieldC
request.session['filters'] = filters
else:
filter = FilterForm(nums)
filters = request.session['filters']
filter.fields['fieldA'].initial = filters['fieldA']
filter.fields['fieldB'].initial = filters['fieldB']
filter.fields['fieldC'].initial = filters['fieldC']
if filters['fieldA']:
records = records.filter(fieldA=filters['fieldA'])
if filters['fieldB']:
records = records.filter(fieldB__in=filters['fieldB'])
if filters['fieldC']:
records = records.filter(fieldC=filters['fieldC'])
sort = request.GET.get('sort')
if sort is not None:
headers = request.session['headers']
if headers[sort] == "des":
records = records.order_by(sort).reverse()
headers[sort] = "asc"
else:
records = records.order_by(sort)
headers[sort] = "des"
request.session['headers'] = headers
return render_to_response("secure/table.html",{'user':request.user,'profile':request.user.get_profile(),'records':records,'fform':filter})
Я изменил большую часть своего кода, чтобы теперь использовать сеансы.Работает нормально.Вы думаете, это хороший способ сделать это?
