1)string

• The common attributes used for every attribute.

2) required

• This is used to take input value from user compulsory.
• It has True and False types input.
• Example:

3) help

• This is used to give some additional information to field name 
• it give information in text value
• Example:

​ ​field_name=fields.Integer(string=”Age”,help=”This is important to write”)

4) Default

• By this we can set default value in any field
• Example:

​ ​field_name=fields.Char(string=”Your name”,default=”Dipanshu”) 

• So by this Dipanshu is already set in Your name field and we can edit it.

5) Copy

• It is used to make duplicate records .
• It has True or False in Input value and by default the value is True. 
• So if we do not want to make a duplicate record then we can write False in it.
• Example:

​ ​field_name=fields.Char(string=”Your name”,copy=False)

6) Readonly

• We only can read value 
• We can not modify the value when we give Readonly=True
• It has True or False value. If we give True then we only read that field value.
• Example:

​ ​field_name=fields.Char(string=”Your name”,default=”dipanshu”,readonly=True)

• so that we can not change this field name.

7) Invisible

• it is used to show or hide our field name in the object
• It also has two value : True and False
• If we give invisible = True then the field name is hidden from the display.
• Example:

​ ​field_name=fields.Char(string=”Your name”,invisible=True)
