我正在Web2Py中接受一些參數並將它們插入到表中的Web服務。我收到以下錯誤，而我在這1個表web2py TypeError：id（）只需要一個參數（0給出）

模型插入數據是這樣的
########################################
db.define_table('t_wish',
Field('id','id',
represent=lambda id:SPAN(id,' ',A('view',_href=URL('wish_read',args=id)))),
Field('f_user_id', type='string',

format='%(f_user_id)s',
migrate=settings.migrate)
db.define_table('t_wish_archive',db.t_wish,Field('current_record','reference t_wish'))
代碼中插入的數據是這樣的
#Creating a wish
def createwish():
try:
user_id = request.vars['id']
category_id = request.vars['category_id']
sub_category_id = request.vars['sub_category_id']
min_price = request.vars['min_price']
max_price = request.vars['max_price']
location_range = request.vars['loc_range']
keywords = request.vars['keywords']
except:
raise HTTP(400, 'BAD REQUEST: Requires all params - id, category_id, sub_category_id, min_price, max_price, loc_range, keywords')
# try:
wish_id = db.t_wish.insert(f_user_id = id, f_category_id = category_id, f_sub_category_id = sub_category_id, f_min_price = min_price, f_max_price = max_price, f_location_range = location_range, f_keywords = keywords)
return sj.dumps({'result':'success', 'wish_id':wish_id})
#except:
# raise HTTP(500, 'Internal Server Error')
任何想法？
不能使用「身份證」'id'不是關鍵字：'>>> import關鍵字\ n > >> keyword.iskeyword（'id'）\ n False這是一個內建的。儘管如此，你不應該給變量名稱與內建函數衝突，因爲它會導致這種錯誤。 – hughdbrown
