in this blog we will explain example to generate random number of 4 digits in odoo so let us start
- First we have to import choice class from random package as bellow
from random import choice
- Then we have to import digits class from string package as bellow
from string import digits
- Last we can use the function bellow that will return the random number
def _default_random_pin(self):
return ("".join(choice(digits) for i in range(4)))
In this blog we will explain how to add value for many2one field in the xml demo data file in odoo , so let us start
First let us say we have python object by the name 'report.create' which is contain the model_id field which is many2one field from 'ir.model' as bellow
class ReportCreater(models.Model):
_name = 'report.creater'
model_id = fields.Many2one(
'ir.model', string='Model', required=True, ondelete="cascade",
help="The type of document this template can be used with")
and we want to create demo data for this object and the records from the demo data must contain the model_id field , so we can do it as bellow
<odoo>
<data noupdate="0">
<record id="simple_contract_template" model="desined.report.template">
<field model="ir.model" name="model_id" search="[('model', '=', 'res.partner')]"/>
</record>
</data>
</odoo>
*NOTES
I face the error bellow we I tried to install some module in odoo 14 , the error is
ValueError: Field mark_id of model rep.template is defined as ondelete='restrict
of course ! , I have model by name 'rep.template', in which that I have many2one file defined as bellow
mark_id = file.Many2one('rep.mark', string='Mark')
and I face the error above because of this field , so to fix this error I rewrite this field as bellow
mark_id = file.Many2one('rep.mark', string='Mark', ondelete="cascade")
On this topic we will explain how to deal with github from terminal
First : if you don't have account on github , you can create it from here , then follow me :)
Login to git hub from terminal by the command
git config --global user.email "your_email_address@example.com"
Initialized empty git repository
git init
Remove the initialized empty repository
rm -rf .git
Show repository activity log
git log
Clone files from the repository in the current folder
git clone repo_url . // the . means that we want to clone files in the current directory
View the information about the repository
git remote -v
List all branches in the repository
git branch -a
Show the changes that we had made to the code
git diff
Add all working files to the staging
git add -A
Commit the add files in the local device
git commit - m "Some Message :)"
Push the committed changes locally to the remote repository at git.com (2 steps < pull and push >)
git pull origin branch_name // to check if any other developer make any changes in the repository (origin is the name of the remote repository)
git push origin branch_name // to push our changes to the repository (branch)
Create new branch
git branch branch_name // this will create new branch in the current repository
Switch the current working with branch
git checkout branch_name
Push changes to specific specific branch in the remote repository
git push -u origin branch_name // #not : we can to pull by this way too
Merge a branch with the current branch
git branch --merged
git merge branch_name
Delete Branch
git branch -d branch_name // this will delete the branch from the local
git push origin --delete branch_name // this will push the deleted branches to the remote repository

I this topic we will explain how to configure nginx for localhost odoo server by steps, but before that you need to install nginx and running odoo server and then follow the steps
First : go to /etc/nginx/enable-sites and add new configuration file by the name odoo14.localhost which will configure your nginx for odoo local server
Second : open the file /etc/hosts and add the localhost (127.0.0.1) to the file as bellow
Third : add the ssl certification by going to etc/ssl and create new folder by name nginx and inside it run the command bellow
openssl req -x509 -new -newkey rsa:2048 -nodes -keyout odoo.key -days 9999 -out odoo.crt
###
odoo14.localhost file will be as

# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
The odoo configuration file will be as

admin_passwd = Ahmmar

db_name = False
db_user = ahmed

logfile = /var/log/odoo14/odoo14-service.log
###
Here are some important commands
nginx -t >> to test if the nginx conf files are okay
systemctl restart nginx.service >> to restart nginx
sudo su -- >> to login as root user
*NOTE
after doing the above configuration you have to restart the odoo server and go to your browser and open https://localhost which will open the creation page for new database
We use nginx with odoo as reverse proxy act as an intermediary between the clients and the Odoo server , and in this topic we will explain how to use nginx , ssl and reverse proxy to odoo
Now as we know , odoo is web base and that means we can access the odoo server from the internet if it has public ip address , so why we use Nginx as reverse proxy ?
Answer : because of
Before configure nginx to be reverse proxy to odoo you have to check the following points
open the file bellow and change odoo.example.com to your domain
/etc/nginx/sites-enabled/odoo.example.com upstream odoo {

NGINX is open source software for web serving, reverse proxying, caching, load balancing, media streaming, and more. It started out as a web server designed for maximum performance and stability. In addition to its HTTP server capabilities, NGINX can also function as a proxy server for email (IMAP, POP3, and SMTP) and a reverse proxy and load balancer for HTTP, TCP, and UDP servers. (ref)
open your terminal and write down the commands bellow
sudo apt-get update
sudo apt install nginx
after install it , you can check it by open "localhost" on your browser , and if it open the page on the image above that means it installed successfully
Default page is placed in /var/www/html/ location. You can place your static pages here, or use virtual host and place it other location
