<!-- """Create Kanban View""" -->

  <record id="view_ssc_projects_kanban" model="ir.ui.view">
    <field name="name">ssc.projects.kanban</field>
    <field name="model">ssc.projects</field>
    <field name="arch" type="xml">

rounding in odoo

 In this blog we will explain how we can make rounding in odoo for float numbers
         

          as we know 10/3 = 3.333333333333X , and we can make rounding for this value as 3.34 or 3.334 or 3.33 or 3.3 or 3.333 , that is means we have more than one way to make rounding in math , so how can we make rounding in odoo ?

To make rounding in odoo we can use round() function id takes 2 arguments the first one it the float number that we want to round it  ,and the second one is the number of rounding index so the Rule as

num = round(float_number,index_number)

so if we want to round 10/3 for 2 index with will be 3.34 we can do it as bellow

num = round(10/3,2)

Another way to make rounding in odoo is by using float_round() function with can takes 4 arguments as bellow

num = float_round(10/3,precision_digits=2, precision_rounding=None, precision_method='up' )

less porblem with odoo 10

 

I had some problem with odoo 10 UI after installing some theme module , and I tried many ways to fix it , and only one way worked with me , which by running the command bellow in the terminal

sudo npm install -g less@3.0.4 less-plugin-clean-css

report color from user in odoo

 

In this blog we will explain how read report color from user in odoo . so let us make an example 

First : we have to define char field that will contain the color rbg as bellow

color = fields.Char(string="Color")

Second : create the view for this field as bellow 

<field name="color" widget="colorpicker"/>

or
<field name="color" widget="color"/>

after that the view will look like bellow 

 

Third : we can read our color in the report template as bellow

background-color:<t t-esc="color"/>!important; // to make it as back groud color for some element 

color:<t t-esc="color"/>!important; // to make it as text color

...

Eg : say we want to add it as back ground color for td in a table so we can do it as bellow

&lt;td style="width:100px;font-size:14px; border: 1px solid black;padding-top:2px; padding-bottom:2px;background-color:<t t-esc="color"/>!important; font-size: 14px; text-align:center;font-weight:bold;"
      <span t-esc="field_name"/>

&lt;/td &gt;



I used this with odoo 11 , and it worked :)
