Set up a development environment with PyCharm

  • Create an Odoo? folder and clone Odoo with the command git clone –depth 1 –branch ?.0 https://www.github.com/odoo/odoo.
  • Create a virtual environment in that folder (with Python3 since Odoo 11) …
    • virtualenv ./venv -p /usr/bin/python(3)
    • source ./venv/bin/activate
    • pip(3) install -r odoo/requirements.txt (If psycopg2 is version 2.7.1 in this file, set it to 2.7.3.1 first.)
    • deactivate
  • Open the Odoo? folder in PyCharm …
    • Change the standard Python interpreter of your project to the newly created environment … File > Settings > Project: Odoo? > Python Interpreter > Cog icon + Add > Select Odoo?/venv/bin/python(2.7).
    • Make a run configuration …
      • + Python
      • Script path = Odoo?/odoo/odoo -bin (or openerp-server before Odoo10)
      • Parameters
        • Odoo should be able to connect to your database, so make sure the params –db_user and –db_password are correctly set.
        • If you have more environments of Odoo of even different versions, it’s a good idea to force the selection of the correct database by setting –db-filter=^Odoo?$ as parameter.

XML

General tips

  • AVOID COMMENTS IN YOUR XML FILES WHICH LEAD TO UNCLEAR ERROR MESSAGES!
  • Add a space with ampersand hashtag 160 ;

AssertionError: Element odoo has extra content: record, line 3

1/ If you are extending a view, check if your model name is the one of the parent view.

2/ To spot invalid syntax, go to an online relax ng validator like https://www.liquid-technologies.com/online-relaxng-validator. Add the contents of your view in the first input field, the contents of odoo/odoo/import_xml.rng in the second and validate. The errors here will give you precise info on the error. Here is an example …

How to extend/overrule/override <record>?

<record>s of model ‘ir.ui.view’ have an inherit_id property …

<record id="product_template_search_view" model="ir.ui.view">
    <field name="model">product.template</field>
    <field name="inherit_id" ref="product.product_template_search_view" />
    <field name="arch" type="xml">
        <field name="name" position="after">
            <field name="product_brand_id" />
        </field>
    </field>
</record>

<record>s of models other than ‘ir.ui.view’ do not work with an inherit_id. If you want to change a field value of a record, you should copy the definition of the <record> in your module, prefix the id with the original module name (+ dot) and include the field you wish to change like for example …

<record id="purchase_requisition.type_multi" model="purchase.requisition.type">
   <field name="exclusive">exclusive</field>
</record>

If that <record> is wrapped in a noupdate=”1″ you should make the record writable first (and unwritable again after) like this …

<odoo noupdate="0">
   <function name="write" model="ir.model.data">
      <function name="search" model="ir.model.data">
         <value eval="[('module', '=', 'purchase_requisition'), ('name', '=', 'type_multi')]"/>
       </function>
      <value eval="{'noupdate': False}" />
   </function>
   <record id="purchase_requisition.type_multi" model="purchase.requisition.type">
       <field name="exclusive">exclusive</field>
   </record>
   <function name="write" model="ir.model.data">
      <function name="search" model="ir.model.data">
         <value eval="[('module', '=', 'purchase_requisition'), ('name', '=', 'type_multi')]"/>
      </function>
      <value eval="{'noupdate': True}" />
   </function>
</odoo>

Views

How to add default views for a model?

Just create an action and menu item for the model …

    <record id="product_template_attribute_action" model="ir.actions.act_window">
        <field name="name">Product Template Attributes</field>
        <field name="res_model">product.template.attribute.line</field>
        <field name="view_mode">tree,form</field>
    </record>
    <menuitem id="menu_product_template_attribute_action"
              action="gun_product.product_template_attribute_action"
              parent="sale.prod_config_main"
              groups="product.group_product_variant"
              sequence="2"/>
How to control the order of view inheritance?
<record id="product_template_tree_view" model="ir.ui.view">
    <field name="model">product.template</field>
    <field name="inherit_id" ref="product.product_template_tree_view"/>
    <field name="priority" eval="32"/>

The default priority of a view is 16. The definition above will apply this extension after most inherited views.

How to create xpath expressions?

https://docs.python.org/3/library/xml.etree.elementtree.html#supported-xpath-syntax

<xpath expr="//field[@name='invoice_line_ids']/tree/field[@name='company_id']" position="after">
<xpath expr="//div[hasclass('o_primary')]" position="after">
<xpath expr="//link[last()]" position="after">
<xpath expr="." position="inside">
<xpath expr="//templates/descendant::field[@name='partner_id']" position="after">
<xpath expr="//button[@name='action_timer_start'][hasclass('btn-primary')]" position='after'>
How to move a field in a view?
<data>
  <xpath expr="//field[@name='active']" position="before">
    <xpath expr="//field[@name='barcode']" position="move"/>
  </xpath>
</data>

Before Odoo 12 you first have to set the moving field to invisible and adding it again at the right position!

<field name="product_brand_id" position="attributes">
    <attribute name="invisible">1</attribute>
</field>
<field name="name" position="before">
    <field name="product_brand_id"/>
</field>
