属性就是属性。每个对象都有一些属性。在Odoo中，每个模型、字段等都有一些属性。在这里，我们将讨论一些模型属性。

The most common attributes for a model are String, Required, Default, Readonly, Help, Index, etc.

模型最常见的属性是字符串、必选、默认、只读、帮助、索引等。

String

字符串

The common attribute used for every field is String.

每个字段使用的公共属性是String。

name = fields.Char(string="Field name")

Here, “name” is the variable name, “Char” is the field type, and string is the attribute. The string values are always added in single or double quotes. That value will be shown on the UI.

这里，“name”是变量名，“Char”是字段类型，string是属性。字符串值始终添加在单引号或双引号中。该值将显示在UI上。

Required

必须的

By default, required is false. We can add required=True, which will make them as mandatory field

默认情况下，required为false。我们可以添加required=True，这将使它们成为必填字段

name = fields.Char(string="Field name", required=True)

Values that can be given to required fields are True or False.

可以赋予必填字段的值为True或False。

Help

帮助

Provides help tooltips for users in the UI.

在UI中为用户提供帮助工具提示。

name = fields.Char(string="Name", help="Enter the description")

Here, I have given the help attribute to the name field.

在这里，我为name字段赋予了help属性。

Index

索引

Requests that Odoo creates a Database Index on the column.

请求Odoo在列上创建数据库索引。

name = fields.Char(string="Record name", index=True)

The values that can be given to the index attribute are True or False. By default, the value is False.

可以赋予index属性的值为True或False。默认情况下，该值为False。

Default

默认值

We can assign default values for the fields by using the default attributes.

我们可以使用默认属性为字段分配默认值。

name = fields.Char(string="Field name", default='John')

The default value of the name field will be the value of the default.

名称字段的默认值将是默认值。

Readonly

只读

If we make a field as a read-only field, then we cannot change the field value manually.

如果我们将字段设置为只读字段，则无法手动更改字段值。

name = fields.Char(string="Name", readonly=True)

Readonly has two values, True and False, readonly=True means that the value of the field cannot be changed.

Readonly有两个值，True和False，Readonly=True表示字段的值不能更改。

Translate

翻译

When the translate attribute is set to true, it makes the field translatable. Depending on the user interface language, it can hold different values.

当translate属性设置为true时，它将使字段可翻译。根据用户界面语言的不同，它可以保存不同的值。

name = fields.Char(string="Name", translate=True)

Groups

组

It is used to make the field only available for some user groups.

它用于使该字段仅对某些用户组可用。

name = fields.Char(string="Name", groups=”base.user_group”)

States

状态

It helps the user interface to assign value for the necessary, readonly, and invisible attributes dynamically based on the state field's value.

它帮助用户界面根据状态字段的值动态地为必要的、只读的和不可见的属性赋值。
