Example :
We created view with button that call wizard enable user to enter new password and click button to change his password with the new one , so this button must call python function that change his password and this function can be just as bellow
def change_password(self,user_id,new_password):
user = self.env['res.users'].search([('id','=',user_id)])
user.sudo().write({'password':new_password})
1- create new class which is inherits res.users class
2- create new char field which will contain the token , and it must be compute field
3- create function to generate the token
as bellow
from odoo import models, fields, api, _
import hashlib
import hmac
import base64
import string
import math, random
from passlib import pwd, hash
class ResUsers(models.Model):
_inherit = 'res.users'
access_token = fields.Char(string="Access Token", readonly=True, compute='generate_access_token')
def generate_access_token(self):
for rec in self:
token = ""
# first way
# pre_token = rec.name+rec.login
# token = hash.pbkdf2_sha512.hash(pre_token)
# second way
hash_object = hashlib.sha256(rec.password.encode())
token = hash_object.hexdigest()
rec.sudo().write({'access_token': token})
for an example : we want to generate url for the pdf invoice , so we can create function that takes the invoice id and return the url for the pdf invoice as bellow
from odoo import api , fields, models,SUPERUSER_ID,_
def generate_pdf_invoice_url(self , invoice_id):
# pdf = request.env.ref('module_name.report_action_id').with_user(SUPERUSER_ID)._render_qweb_pdf([invoice_id.id])
pdf = request.env.ref('account.account_invoices').with_user(SUPERUSER_ID)._render_qweb_pdf([invoice_id.id])
pdf_invoice = request.env['ir.attachment'].sudo().create({
'name': invoice_id.name,
'type': 'binary',
'datas': base64.b64encode(pdf[0]),
'store_fname': invoice_id.name,
'res_model': 'account.payment',
'res_id': invoice_id.id,
'mimetype': 'application/x-pdf'
})
pdf_file_url + 'http://'+request.httprequest.__dict__['environ']['HTTP_HOST']+'/web/content/%s' % (pdf_invoice.id)
return pdf_file_url
Let us say we are building an APIs for our odoo system and we have to build api to return the product data and we must return the product image as url so we can create function that generate this url as bellow
First :
@http.route(['/web/product_image',
'/web/product_image/<int:rec_id>',
'/web/product_image/<int:rec_id>/<string:field>',
'/web/product_image/<int:rec_id>/<string:field>/<string:model>/'], type='http', auth="public")
def content_image_partner(self, rec_id, field='image_128', model='product.template', **kwargs):
return self._content_image(id=rec_id, model='product.template', field=field,
placeholder='user_placeholder.jpg')
Second :
def _content_image(self, xmlid=None, model='ir.attachment', id=None, field='datas',
filename_field='name', unique=None, filename=None, mimetype=None,
download=None, width=0, height=0, crop=False, quality=0, access_token=None,
placeholder=None, **kwargs):
status, headers, image_base64 = request.env['ir.http'].binary_content(
xmlid=xmlid, model=model, id=id, field=field, unique=unique, filename=filename,
filename_field=filename_field, download=download, mimetype=mimetype,
default_mimetype='image/png', access_token=access_token)
return Binary._content_image_get_response(
status, headers, image_base64, model=model, id=id, field=field, download=download,
width=width, height=height, crop=crop, quality=quality,
placeholder=placeholder)
Third :
def generate_product_image_url(self,product_id):
img_url = ''
# or we can set default image for each product as
# img_url = 'http://'+request.httprequest.__dict__['environ']['HTTP_HOST']+'/module_name/static/src/img/default.png'
request.env.cr.execute(
"SELECT id FROM ir_attachment WHERE res_model='product.template' and res_id=%s",[product_id]
)
if request.env.cr.fetchone():
img_url_pre = 'http://'+request.httprequest.__dict__['environ']['HTTP_HOST']+'/web/product_image/%s/image_1920/product.template' % product_id,
img_url = img_url_pre[0]
return img_url
so let us say that we made an integration with external api to get new customer data with is include image_file and we want to save this image into odoo database , so first we must create function that takes the image_file as an input and return the image as data (read the binary file), second we can pass the image data to image field in res.partner object in odoo to create new customer with image , and the function can be just as bellow
def load_image_from_binary_file(self, file):
return base64.b64encode(file.read())
so let us say that we made an integration with external api to get new customer data with is include image_url field and we want to save this image into odoo database , so first we must create function that takes the image_url as an input and return the image as data , second we can pass the image data to image field in res.partner object in odoo to create new customer with image , and the function can be just as bellow
def load_image_from_url(self, url):
data = base64.b64encode(requests.get(url.strip()).content).replace(b'\n', b'')
return data
if we want to get the server URL for the current odoo module we can get it as below
#for python model
server_url = self.env['ir.config_parameter'].get_param('web.base.url')
#for http.controller
1/ from odoo.http import request
2/ server_url = request.env['ir.config_parameter'].get_param('web.base.url')
There are two main issues must of us facing with the QR code in Odoo invoice & these issues are 1/ QR code displayed as broken image w...
