Peewee - Sorting

It is possible to select records from a table using order_by clause along with model’s select() method. Additionally, by attaching desc() to the field attribute on which sorting is to be performed, records will be collected in descending order.

Example

Following code display records from contact table in ascending order of City names.

rows=Contacts.select().order_by(Contacts.City)
print ("Contact pst in order of city")
for row in rows:
   print ("RollNo:{} Name: {} City:{}".format(row.RollNo,row.Name, row.City))

Output

Here is the sorted pst which is arranged according to ascending order of city name.

Contact pst in order of city
RollNo:107 Name: Beena City:Chennai
RollNo:102 Name: Amar City:Delhi
RollNo:108 Name: John City:Delhi
RollNo:103 Name: Raam City:Indore
RollNo:101 Name: Anil City:Mumbai
RollNo:106 Name: Hema City:Nagpur
RollNo:104 Name: Leena City:Nasik
RollNo:109 Name: Jaya City:Nasik
RollNo:110 Name: Raja City:Nasik
RollNo:105 Name: Keshav City:Pune

Example

rows=Contacts.select().order_by(Contacts.Name.desc())
print ("Contact pst in descending order of Name")
for row in rows:
   print ("RollNo:{} Name: {} City:{}".format(row.RollNo,row.Name, row.City))
