Debug the Odoo in Ubuntu with different user name

Once we've installed the Odoo as a service in Ubuntu, Odoo will be started up automatically. If we want to debug the Odoo, we should stop the Odoo service first. Also, we will encounter the "Peer authentication failed for user "odoo"" error if our login user name is not odoo. In order to conquer these problems we should do the following steps:

1. Stop service:

sudo service odoo stop

2. set the user odoo as a trusted user to all databases from local:

sudo nano /etc/postgresql/9.3/main/pg_hba.conf

 

then add the following line into the file:

local all odoo trust

 

then restart the postgresql:

sudo service postgresql restart

3. Start odoo with the db user odoo:

cd /usr/bin
./odoo.py -r odoo


Reference:

Peer authentication failed for user "odoo"

Build our own Linux Web Server with XAMPP

If we want to set up our own web server on the Linux platform,  installing an XAMPP (Apache+MariaDB+PHP+Perl on the different platforms) will be the easiest way.  Here I show the basic installation procedures as follows:

1. Download a copy of an  XAMPP Linux version from the site Download XAMPP   . For example,  we can download the file

https://www.apachefriends.org/xampp-files/5.5.35/xampp-linux-x64-5.5.35-0-installer.run

2. Run cd command to go to your directory and execute the installation file:

sudo chmod +x xampp-linux-x64-5.5.35-0-installer.run
sudo ./xampp-linux-x64-5.5.35-0-installer.run

We will see a newly generated pop-up window. Just click the Next button and uncheck the  “Learn more about BitNami for XAMPP” checkbox. We'll install the XAMPP and run it.

To stop the XAMPP, we can:

sudo /opt/lampp/lampp stop

To strat  the XAMPP, we can:
sudo /opt/lampp/lampp start

We can try the url http://localhost from our browser to see the page on our server.

And then one important thing to do- set the Security settings:

sudo /opt/lampp/lampp security

Always say yes by pressing Enter key and key in our password.

Install a Camera and a Realtime Stream Server on the Raspberry Pi

 

A Raspberry Pi with a camera can become a real time stream sever. We can select either
UV4L or mjpg-streamer to transmit its streaming data.

UV4L(User space Video4Linux collection) includes a full-featured Streaming Server component providing a set of solutions for live audio & video streaming, casting/mirroring and conferencing over the web. 

On the other hand, the MJPG-streamer takes JPGs from Linux-UVC compatible webcams, file system or other input plugins and streams them as M-JPEG via HTTP to web browsers, VLC and other software.

We can install both on the Raspberry Pi.

First, we connect the Camera bus to the Raspberry Pi board, and the start the raspi-config:

sudo raspi-config

Select item 6 to enable the camera:
6 Enable Camera .......                

Reboot and run tests:

raspistill -o cam.jpg
raspivid -o vid.h264

The image/video window will be shown on the console.



Install MJPEG Stream components:

sudo apt-get update
sudo apt-get install subversion
sudo apt-get install libjpeg8-dev
sudo apt-get install imagemagick
sudo apt-get install libv4l-dev

Get mjpg-streamer from svn:

svn co https://svn.code.sf.net/p/mjpg-streamer/code/
cd code/mjpg-streamer
make
sudo make install


wget http://www.linux-projects.org/listing/uv4l_repo/lrkey.asc && sudo apt-key add ./lrkey.asc
sudo nano /etc/apt/sources.list

Add this line to the file and exit:

deb http://www.linux-projects.org/listing/uv4l_repo/raspbian/ wheezy main


sudo apt-get update
sudo apt-get install uv4l uv4l-raspicam
For autostart service:

sudo apt-get install uv4l-raspicam-extras

sudo reboot

Install uv4l:
sudo pkill uv4l
sudo apt-get update
sudo apt-get install uv4l-uvc
sudo apt-get install uv4l-xscreen
sudo apt-get install uv4l-mjpegstream
sudo apt-get install uv4l-server
sudo reboot

The WebRTC extension for the Streaming Server is also available:
sudo apt-get install uv4l-webrtc
uv4l --auto-video_nr --driver raspicam --encoding mjpeg --server-option '--port=9000' or
uv4l --auto-video_nr --driver raspicam --encoding mjpeg --server-option '--port=9000' --driver raspicam --rotation 180 --width 352 --height 288
Use Browser to link to the uv4l server:    
http://192.168.0.x:9000


sudo modprobe bcm2835-v4l2
cd code/mjpg-streamer
./mjpg_streamer -i "./input_uvc.so" -o "./output_http.so -w ./www"

Basic Tutorial Samples of Odoo Object Relational Mapping(ORM)

The traditional Odoo Object Relational Mapping(ORM) API passes the database cursor, user id, context dictionary and record ids(usually denoted as cr, uid, context, ids) to all methods. For example:
    self.browse(cr, uid, sids, context=context)

These parameters have been removed from the new Record style API since Odoo 8. But the programs of Odoo are written in traditional style. So it is still very important to understand how it works.

The basic ORM method is search(). We can provide some searching criteria (domain) to the method like [('uuid', '=', uuid)] to screen out the records we want. And the browse() returns the records we need according the input ids parameter.

Here is the sample of search() and browse():

// Sample of reading own records: search(),browse() directly

    def is_in_session(self, cr, uid, uuid, user_id, context=None):
        """ return if the given user_id is in the session """
        sids = self.search(cr, uid, [('uuid', '=', uuid)], context=context, limit=1)
        for session in self.browse(cr, uid, sids, context=context):
                return user_id and user_id in [u.id for u in session.user_ids]
        return False

If we need to access the data of another class, we should use the pool[] to access that class first.

// Sample of Reading records of other class: use pool[] first
    def users_infos(self, cr, uid, ids, context=None):
        """ get the user infos for all the user in the session """
        for session in self.pool["im_chat.session"].browse(cr, uid, ids, context=context):
            users_infos = self.pool["res.users"].read(cr, uid, [u.id for u in session.user_ids], ['id','name', 'im_status'], context=context)
            return users_infos

 

Another useful method is  search_read(). It is a combination of a search() and a read(). We need to prepare the domain for search() and the fields list for read(). Look at this example:

 

// Sample of Odoo ORM search_read(): Performs a search() followed by a read()

    def session_info(self, cr, uid, ids, context=None):
        """ get the session info/header of a given session """
        for session in self.browse(cr, uid, ids, context=context):
            info = {
                'uuid': session.uuid,
                'users': session.users_infos(),
                'state': 'open',
            }
            # add uid_state if available
            if uid:
                domain = [('user_id','=',uid), ('session_id','=',session.id)]
                uid_state = self.pool['im_chat.conversation_state'].search_read(cr, uid, domain, ['state'], context=context)
                if uid_state:
                    info['state'] = uid_state[0]['state']
            return info

The last sample of this tutorial is write().  Just use it to write data back to the records.

// Sample of Odoo ORM write:

    def update_state(self, cr, uid, uuid, state=None, context=None):
        """ modify the fold_state of the given session, and broadcast to himself (e.i. : to sync multiple tabs) """
        domain = [('user_id','=',uid), ('session_id.uuid','=',uuid)]
        ids = self.pool['im_chat.conversation_state'].search(cr, uid, domain, context=context)
        for sr in self.pool['im_chat.conversation_state'].browse(cr, uid, ids, context=context):
            if not state:
                state = sr.state
                if sr.state == 'open':
                    state = 'folded'
                else:
                    state = 'open'
            self.pool['im_chat.conversation_state'].write(cr, uid, ids, {'state': state}, context=context)
            self.pool['bus.bus'].sendone(cr, uid, (cr.dbname, 'im_chat.session', uid), sr.session_id.session_info())

Experience of Installing Odoo 8.0 on the Ubuntu Platform

    I've tested he installation procedures many times by following Odoo document and google search referral, but there is no successful experience.

    The first problem I met was Ubuntu version. I've installed Ubuntu 16.04. But its default Python is version 3. Odoo needs version 2.7. Many blogs have their own scripts to cope with this issue. But I decided to go back to Ubuntu 14.04 to make my life easier.

    Then I downloaded the .Deb files from Odoo and install by double clicking the Deb file and clicking the Install button. But still,it was not working.

    Finally, go back to "apt-get install" follow some steps in the Odoo installation document with some changes. It works eventually!

 

The steps are:
 

Install postgresql:

sudo apt-get install postgresql-9.3

Install pgadmin3:

sudo apt-get install pgadmin3

Install Odoo on Ububtu 14.04.4

sudo wget -O - https://nightly.odoo.com/odoo.key | sudo  apt-key add -

cd /etc/apt

sudo vi sources.list

Insert "deb http://nightly.odoo.com/8.0/nightly/deb/ ./" into the file

sudo apt-get update 

sudo apt-get install odoo

Reference:

Installing Odoo — odoo 8.0 documentation

 

In this document, there is a section teaching  us how to install in the Deb style Linux:

Deb

To install Odoo 8.0 on Debian-based distribution, execute the following commands as root:

# wget -O - https://nightly.odoo.com/odoo.key | apt-key add -
# echo "deb http://nightly.odoo.com/8.0/nightly/deb/ ./" >> /etc/apt/sources.list
# apt-get update && apt-get install odoo

This will automatically install all dependencies, install Odoo itself as a daemon and automatically start it.

Danger

to print PDF reports, you must install wkhtmltopdf yourself: the version of wkhtmltopdf available in debian repositories does not support headers and footers so it can not be installed automatically. The recommended version is 0.12.1 and is available on the wkhtmltopdf download page, in the archive section. As there is no official release for Debian Jessie, you can find ours on http://nightly.odoo.com/extra/.

Configuration

The configuration file can be found at /etc/odoo/openerp-server.conf

When the configuration file is edited, Odoo must be restarted using service:

$ sudo service odoo restart
Restarting odoo: ok

How To Create a New Module on the Odoo

If we are trying to build a new module of the Odoo, we should type the command like:


python odoo.py scaffold Academy openerp/my-modules

This command generates the Odoo module scaffold named Academy to the directory openerp/my-modules. But when we try to install this new Academy module under the Setting page, we cannot find an Academy module for us to install.

In order to find this new module, we need to use the "Update Module List" option.

If we can't find the option "Update Module List" either, we need to enable the "Technical Features" checkbox in our current user's settings.

Need to do some steps:

First, select side menu Users-Users  and click the Administration user. Then we can see the form view of the User/Administrator. Click the "Technical Features" checkbox and save the settings.

Then, select side menu of Modules-"Update Module List", and click the Update button.

 

Finally,  select side menu Modules-Local Modules,remove all filters and sort the module list. We will see the Academy module in the first position.

Going to http://localhost:8069/academy/academy/  will see the new module.

If we've added some  templates or have modified codes of the module Academy , we will need to upgrade the module again.

We should restart Odoo and update the module's data (to install the template) by going to Settings-Modules-Local Modules-Academy and clicking the Upgrade button.

Going to http://localhost:8069/academy/academy/  should show new updated results.

Coding 5 Languages at once: If Statement

    If we want computer do something based on different conditions, we can use the "IF" statement.
    If the "If condition Then" statement finds the result is True then if will continue the next statement. Otherwise, it will find the next "ElseIf condition Then" statement to test another condition. If no condition is matched, it will find the "Else" statement to go. Or the "End If" statement, if there is no "Else" found.
    Other languages use the "{...}" to define a black of statements. If the condition is True, it will perform all statements within the block.

BASIC:
        ' *******************************************
        ' Condition statement (If..ElseIf..Else..End If)

Learn Coding Five Languages at once: For Statement

If we want to perform an instruction many times, we can copy this instruction many times or use a "For...Next" block. This "For" statement assigns an initial value to a variable and change it up to the end value stepping with +1 or -1.

For example, "For i=1 to 5 " statement assign value 1 to the variable i and loop it up to the end value 5 with stepping value 1 each time. When program meets the "Next"  statement, it will jump back to the "For" statement. But if the variable exceeds the end value, the program will jump to the statement next to "Next".

Here we show the example of looping five times and print the value of the variable i in five different programming languages:

BASIC:
        ' *******************************************
        ' for loop statement (For..Next)
        ' *******************************************
        Sub ForLoop()
            ' Declare local variable
            Dim i as Integer
            Debug.Print " ";"**** For statement ***";
            Debug.Print
            For i=1 to 5
                Debug.Print " ";"i=";
                Debug.Print " ";i;
                Debug.Print
            Next
        End Sub

C++:
        /* ******************************************* */
        /* for loop statement (For..Next) */
        /* ******************************************* */
        void ForLoop() {
            /* Declare local variable */
            int i;
            printf(" %s" , "**** For statement ***");
            printf("\n" );
            for (i=1; i<= 5; i++) {
                printf(" %s" , "i=");
                printf(" %d" , i);
                printf("\n" );
            }
        }

JAVA:
        // *******************************************
        // for loop statement (For..Next)
        // *******************************************
        public void ForLoop()  {
            // Declare local variable
            int i;
            System.out.print(" "+"**** For statement ***" );
            System.out.println("");
            for (i=1; i<= 5; i++) {
                System.out.print(" "+"i=" );
                System.out.print(" "+i );
                System.out.println("");
            }
        }

Learn Computer Languages from BASIC,C++, JAVA, C# to PHP at once

Computer programming languages from BASIC,C++, JAVA, C#  to PHP seem different, but actually they can do the same task. We can study them all together under some basic topics.

The first lesson of coding to understand assignment like a=a+1. This is not an equation. It simply means compute a+1 and put the result back to a.

Here we list some statements of assignment in five different programming languages: BASIC,C++, JAVA, C# and PHP.



' Value Assignment
iA = 1*2+3/4-5
iB = 1*(2+3)/4-5
iC =iA  Mod  2

' Print  iA,iB,iC

' String Assignment
sS="abc"

' String Catenation
sS=sS+"<>"
sS=sS+"def"

' Print  sS
