CRM多條件查詢 第20天

1、前端**如下：

<

div 
class
="row"
>
<
div 
class
="col-lg-2"
>
<
input 
type
="search"
name
="_q"
class
="form-control"
value
="}"
placeholder
="search by } "
style
="margin-left:15px"
>
div>
<
div 
class
="col-lg-2"
>
<
button 
type
="submit"
class
="btn btn-success"
>search
button
>
div>
div>

def

print("
-->
" ##
model_obj = getattr(models_module,table_name)
#admin_class = king_admin.enabled_admins[crm][userprofile]
#object_list = admin_class.model.objects.all()
object_list,filter_condtions =table_filter(request,admin_class)
#多條件搜尋功能
object_list =table_search(request,admin_class,object_list)
#排序過後的資料
object_list,order_key =table_order(request,object_list)
paginator = paginator(object_list, admin_class.list_per_page) #
show 25 contacts per page
print("
paginator------
",paginator)
page = request.get.get('
page')
try:
query_sets =paginator.page(page)
except
pagenotaninteger:
#if page is not an integer, deliver first page.
query_sets = paginator.page(1) #
#這個是對你的分頁的資料進行取值
except
emptypage:
#if page is out of range (e.g. 9999), deliver last page of results.
query_sets =paginator.page(paginator.num_pages)
print("
query_sets------------
",query_sets)
return render(request,"
kindadmin/table_objs.html
",)

2、搜尋查詢也是在過濾後查詢的，在view.py裡增加：

object_list,filter_condtions =table_filter(request,admin_class)

#多條件搜尋功能
object_list =table_search(request,admin_class,object_list)
#排序過後的資料
object_list,order_key = table_order(request,object_list)

獲取請求過來的_q值，然後利用q()去或查詢，起初我沒有判斷search_value，導致我重新進入頁面說none是不能夠查詢的：

#

q用法from django.db.models import
q>>> from perfectcrm.perfectcrm.crm import
models
>>> from django.db.models import
q>>> models.customer.objects.values('
qq','
name')
'qq': '
[email protected]
', '
name
': '
江大可'}, , , , 
]>
>>> con =q()
>>> con.connector="or"
qq__contains
','5676567'))
name__contains
','江大
')) #name包函的內容
>>>con
'qq__contains
', '
5676567
'), ('
name__contains
', '
江大'))>
>>> models.customer.objects.values('
qq','
name
').filter(con)'qq
': '
[email protected]
', '
name
': '
江大可'}]>
>>>

def

table_search(request,admin_class,objs):
"""多條件搜尋功能
:param request: 請求的

:return:
"""search_value = request.get.get("

ifsearch_value:

for column in
admin_class.search_fields:

ele =objs.filter(con)
else

return ele

def

table_filter(request,admin_class):
"""進行條件過濾並返回過濾後的資料
"""filter_conditions ={}
for k,v in
request.get.items():
kitem =['

if k in

ifv:

print("

return admin_class.model.objects.filter(**filter_conditions),filter_conditions

多條件查詢

思路 1.獲取引數值 2.生成查詢條件 3.獲取查詢結果 4.繫結查詢選項 呼叫geturlhtml方法生成查詢url 例如 var y2013 pnvshihufu qbeijing sxuhuiqu 得到url變數值 protected string geturlval string name ...

多條件查詢

開發工具與關鍵技術 vs c 當使用者需要通過一定的條件進行範圍查詢的時候,在控制器中,就需要判斷使用者傳來的條件,一般使用者條件查詢會有下拉框,文字框等from表單元件 預設下拉框內的資料已繫結,本文暫不進行時間的範圍查詢 通過獲取這些元件的值,可以方便快捷的採集使用者的資訊 一 查詢 創鍵多條件...
