api decorators in odoo

 

ODOO

 

api

 

 

In this step we will

• explain api decorators
• add age fields for patient object
• calculate age from birthday as example for writing function in odoo

What is api decorators ?

odoo.api.one(method)

odoo.api.multi(method)

Where self is defined as record-set (some records that have related with each other)

EG: model.method(cr, uid, ids, args, context=context)

odoo.api.model(method)

Where self is defined as record-set but its contents is not relevant (some records that have no related with each other)

EG: model.method(cr, uid, args, context=context)

odoo.api.depends(*args)

odoo.api.constrains(*args)

odoo.api.onchange(*args)

odoo.api.returns(model, downgrade=None, upgrade=None)

• add age fields for patient object

we will calculate the age of patient as years, months and days so we must add three fields for age (age_year, age_month, age_day) which will be computed fields that get their values from one function “calculate_age()” so to do that we have to go to ‘clinic.patient’ object and add the code bellow

age_year = fields.Integer(string="Years", compute='calculate_age')

age_month = fields.Integer(string="Months", compute='calculate_age')

age_day = fields.Integer(string="Days", compute='calculate_age')

@api.one

def calculate_age(self):

"""

function to calcolate the age of he user

"""

if self.birth_day :

birth_day = str(self.birth_day)

current_date = str(fields.Date.today())

birth_day_year_as_int = int(birth_day[0]+birth_day[1]+birth_day[2]+birth_day[3])

birth_day_month_as_int = int(birth_day[5]+birth_day[6])

birth_day_day_as_int = int(birth_day[8]+birth_day[9])

current_date_year_as_int = int(current_date[0]+current_date[1]+current_date[2]+current_date[3])

current_date_month_as_int = int(current_date[5]+current_date[6])

current_date_day_as_int = int(current_date[8]+current_date[9])

period_years = current_date_year_as_int-birth_day_year_as_int

period_months = current_date_month_as_int-birth_day_month_as_int

period_days = current_date_day_as_int-birth_day_day_as_int

months_list_1 = ['04','06','09','11']

months_list_2 = ['01','03','05','07','08','10','12']

if period_days < 0:

if str(current_date_month_as_int) == '02':

if current_date_year_as_int%4 == 0:

period_days = 29+period_days

if current_date_year_as_int%4 != 0:

period_days = 28+period_days

for index in range(0,4):

if current_date_month_as_int == int(months_list_1[index]):

period_days = 30+period_days

for index in range(0,7):

if current_date_month_as_int == int(months_list_2 [index]):

period_days = 31+period_days

period_months = period_months-1

if period_months < 0:

period_months = 12+period_months

period_years = period_years-1

self.age_year = period_years

self.age_month = period_months

self.age_day = period_days

Then we will deign view for these field by adding the code bellow to ‘clinic_patient_view.xml’ file

<table style="width:50%;">
    <tr>
        <td style="width:40%;font-size:13px;padding:2px;">
        </td>
        <td style="width:20%;padding:2px;">
            <center>
                years
            </center>
        </td>
        <td style="width:20%;padding:2px;">
            <center>
                months
            </center>
        </td>
        <td style="width:20%;padding:2px;">
            <center>
                days
            </center>
        </td>
    </tr>
    <tr>
        <td style="width:40%;font-size:13px;padding:2px;">
            <b>
                Age
            </b>
        </td>
        <td style="width:20%;padding:2px;">
            <center>
                <field name="age_year" />
            </center>
        </td>
        <td style="width:20%;padding:2px;">
            <center>
                <field name="age_month" />
            </center>
        </td>
        <td style="width:20%;padding:2px;">
            <center>
                <field name="age_day" />
            </center>
        </td>
    </tr>
</table>
