给 Odoo 开发者的快速上手指南

class Partner(models.Model):
    _name = 'res.partner'
    _description = 'Partner'
 
    name = fields.Char(string='Name', required=True)
    email = fields.Char(string='Email')
    age = fields.Integer(string='Age')
    is_company = fields.Boolean(string='Is Company')
 
    def get_display_name(self):
        return f"{self.name} ({self.email})"

{
    public string Name { get; set; } = "";
    public string? Email { get; set; }
    public int Age { get; set; }
    public bool IsCompany { get; set; }
 
    public string GetDisplayName()
    {
        return $"{Name} ({Email})";
    }
}

# Odoo
partner = self.env['res.partner'].create({
    'name': 'Tom',
    'email': 'tom@example.com',
    'age': 25
})

// C#
var partner = new Partner
{
    Name = "Tom",
    Email = "tom@example.com",
    Age = 25
};

# Odoo
partners = self.env['res.partner'].search([
    ('age', '>', 18),
    ('is_company', '=', False)
])
 
# 获取第一个
first = partners[0] if partners else None
 
# 遍历
for partner in partners:
    print(partner.name)

// C# (使用 LINQ)
var partners = allPartners
    .Where(p => p.Age > 18 && !p.IsCompany)
    .ToList();
 
// 获取第一个
var first = partners.FirstOrDefault();
 
// 遍历
foreach (var partner in partners)
{
    Console.WriteLine(partner.Name);
}

# Odoo
partner.write({
    'name': 'New Name',
    'age': 26
})

// C#
partner.Name = "New Name";
partner.Age = 26;
// 如果用数据库，需要调用 SaveChanges()

# Odoo
partner.unlink()

// C# (如果用 Entity Framework)
dbContext.Partners.Remove(partner);
dbContext.SaveChanges();

# Python - 动态类型
name = "Tom"
age = 18
price = 19.99
is_active = True
 
# 可以随时改类型
name = 123  # 合法

// C# - 静态类型
string name = "Tom";
int age = 18;
decimal price = 19.99m;
bool isActive = true;
 
// 不能改类型
// name = 123;  // 编译错误！

# Python
if age >= 18:
    print("成年")
elif age >= 13:
    print("青少年")
else:
    print("儿童")

// C#
if (age >= 18)
{
    Console.WriteLine("成年");
}
else if (age >= 13)
{
    Console.WriteLine("青少年");
}
else
{
    Console.WriteLine("儿童");
}

# Python
for i in range(5):
    print(i)
 
for name in names:
    print(name)
 
while count > 0:
    count -= 1

// C#
for (int i = 0; i < 5; i++)
{
    Console.WriteLine(i);
}
 
foreach (var name in names)
{
    Console.WriteLine(name);
}
 
while (count > 0)
{
    count--;
}

# Python
def calculate_total(price, quantity):
    return price * quantity
 
def greet(name="Guest"):
    return f"Hello, {name}"

// C#
public double CalculateTotal(double price, int quantity)
{
    return price * quantity;
}
 
public string Greet(string name = "Guest")
{
    return $"Hello, {name}";
}

# Python

print(len(names))
print(names[0])
 
# 字典
users = {}
