How to process back-end generator parameters with the front-end template language

The database model is as follows:

Class Server (models. Model):
"""
Server information
"""
# asset = models. Onetoonefield (' Asset ')


IDC = models. ForeignKey (Idc,null=true, Blank=true)
Cabinet_num = models. Charfield (' Cabinet number ', max_length=30, Null=true, Blank=true)
Cabinet_order = models. Charfield ("Serial number in cabinet", max_length=30, Null=true, Blank=true)

Business_unit = models. ForeignKey (Businessunit,null=true, Blank=true)

tags = models. Manytomanyfield (TAG)


   server_status_choices = (
(1, ' shelves '),
(2, ' online '),
(3, ' Offline '),
(4, ' bottom shelf '),
    )

server_status_id = models. Integerfield (choices=server_status_choices, default=1)

hostname = models. Charfield (max_length=128, Unique=true)
SN = models. Charfield (' SN ', max_length=128, Db_index=true)
Manufacturer = Models. Charfield (verbose_name= ' manufacturer ', max_length=64, Null=true, Blank=true)
Model = models. Charfield (' model ', max_length=64, Null=true, Blank=true)

MANAGE_IP = models. Genericipaddressfield (' Management IP ', null=true, Blank=true)

Os_platform = models. Charfield (' System ', max_length=16, Null=true, Blank=true)
Os_version = models. Charfield (' System version ', max_length=128, Null=true, Blank=true)

Cpu_count = models. Integerfield (' Number of CPUs ', Null=true, Blank=true)
Cpu_physical_count = models. Integerfield (' CPU physical number ', Null=true, Blank=true)
Cpu_model = models. Charfield (' CPU model ', max_length=128, Null=true, Blank=true)

Create_at = models. Datetimefield (Auto_now_add=true, Blank=true)

Latest_date = models. Datetimefield (Null=true,blank=true)


Class Meta:
verbose_name_plural = "Server table"

def __str__ (self):
Return Self.hostname

For the server_status_id field in the model can only be a number, then how to display the field corresponding to the Chinese information?

This can be written in the View function:

def test (Request):

Server_list=models. Server.objects.all ()

For Server_obj in Server_list:

Server_obj[choice_name] = Server_obj.get_server_status_id_display ()

return render (Request, ' xxxxx.html ', {' server_list ': ser_list})

At this point we call the Get_server_status_id_display () method to display the ID corresponding to the choice Chinese, and re-loop assigned to each object new fields to correspond to choice Chinese.

But what happens if we use JS's additions and deletions to the components? What we got at that time was not a single object, but a database query implemented through AJAX.

At this point we can use the new method, using the template language of the front end to loop our backend to send past generators.

def xxx (data_list):

For I in Data_list:

For j in Models. Server.server_status_choices:
　　　　　　

def test (Request):

Data_list=models. Server.objects.values (' id ', ' server_status_id ')

return render (Request, ' xxxxx.html ', {' data_list ': xxx (data_list)})
