Many2one

A relationship field defining that Model A has a single reference to Model B. A good example of this, in general, is that Sales Order sale.order has a partner_id = fields.Many2one reference to res.partner . This means that each sales order has a single Customer/Partner.

One2many

A relationship field defining that Model A has multiple references to Model B and Model B has a corresponding Many2one. A good example of this, in general, is that Sales Order sale.order has a order_line = fields.One2many reference to sale.order.line and the sale.order.line model has a single reference back to the order via an order_id = fields.Many2one.

Many2many

A relationship field defining that Model A has multiple references to Model B records and Model B has multiple references to Model A records. A good example of this, in general, is that Sales Order sale.order has a tag_ids = fields.Many2many reference to crm.tag.lead. But a single tag can be assigned to many different order records.

Boolean Field

A simple bool type field that stores either a True or a False value.

Integer Field

An int4 type field which stores an integer value.

Float Field

A float8 type field which stores a floating point number.

Monetary Field

A special version of a float8 column which automatically displays on the frontend in a certain currency.

Char Field

A char type column field which will stores string values. This is typically used for short strings because it has a default max value of 255 characters.

Text Field

A text type column field which will store long-form string values. This is typically used for longer strings and descriptions because it has no max value for strings.

Html Field

Another text type column that stores long-form strings, except it assumes that the field will be populated with HTML context. This alters the frontend to display formatted HTML context instead of standard utf-8 text.

Selection Field

A selection or enum type column that defines a set of fixed values that the user can select from. A good example of this is the states field on a sales order. There are many different events hard linked to the sales order states, so we must fix a list of options.

Date Field

A date type column that stores dates without times.

Datetime Field

A datetime type column that stores datetime values.

Binary Field

A bytea type column that stores binary string values. In the case of Odoo it’s base64 encoded binary strings typically.

These fields are ideal for storing documents or images. The frontend of Odoo will then render these via <img/> tags.
