Understanding XML Code in Odoo 18

XML code represents data in a structured format, and it remains a critical part of Odoo regardless of the version. For Odoo 18, you write XML files to configure views, actions, and setup modules. First, you design XML files that properly display kanban views for mobile and desktop users alike. Next, you define tags such as <record>, <field>, and <kanban> accurately. Then, you ensure that every opening tag has a corresponding closing tag to avoid rendering errors. Consequently, the XML file becomes valid and enhances Odoo 18’s functionality.

You often encounter syntax errors when tags are omitted, closed incorrectly, or attributes misformatted. Therefore, you must pay close attention to tag order and element nesting to produce working code. Additionally, you use XML validators and dedicated Odoo editors to support proper syntax.

Recognizing Common XML Syntax Errors and Missing Tags

Before you dive into debugging, you must recognize mistakes that often occur in XML code. For instance, you face errors when you forget to close tags, when a tag is incomplete, or when you misquote attribute values. Next, you check for errors caused by misnaming elements or using invalid characters. Then, you use transitional steps to identify each mistake systematically. Consequently, you achieve a smoother debugging process and a higher level of professionalism in your code.

Moreover, missing tags can disrupt the entire view. In Odoo 18, even minor syntax issues might break the Kanban layout rendering. Therefore, you verify your code with XML validation tools and ensure that every element is correctly nested.

Step 1: Review the Original Code

Below is the sample XML code intended for an Odoo 18 Kanban view with several common mistakes:

<record id="wb_student_kanban_view" model="ir.ui.view">
  <field name="name">wb.student.kanban.view</field>
  <field name="model">wb.student</field>
  <field name="arch" type="xml">
    <kanban class="o_kanban_mobile">
      <templates>
        <t t-name="kanban-box">
          <div class="row">
            <div class="col-8">
              <field name="name" class="fw-bolder"/>
            </div>
            <div class="col-4">
              <field name="student_fees" class="badge rounded-pill"/>
            </div>
          </div>
          <div>
            <strong>School:</strong>
            <field name="school_id"/>
          </div>
        </t>
      </templates>
    </kanban>
  </field>
</record>

In this initial version, you notice that the code does not fully adhere to Odoo 18 best practices due to potential issues with tag closures and missing adjustments for new layout settings. Consequently, you must update and fix these problems.

Step 2: Identify and Correct Errors

After reviewing the original code, you list corrections needed. First, you ensure that the <record> element uses the correct model, which remains "ir.ui.view", and that every <field> tag is formatted properly. Next, you verify that all tags are closed consistently. Then, you confirm that the structure complies with Odoo 18 standards. Moreover, you add any required adjustments, such as using the latest class names or attributes that enhance mobile responsiveness in Odoo 18.

Below is the updated XML code for Odoo 18:

<record id="wb_student_kanban_view" model="ir.ui.view">
  <field name="name">wb.student.kanban.view</field>
  <field name="model">wb.student</field>
  <field name="arch" type="xml">
    <kanban class="o_kanban_mobile">
      <templates>
        <t t-name="kanban-box">
          <div class="row">
            <div class="col-8">
              <field name="name" class="fw-bolder"/>
            </div>
            <div class="col-4">
              <field name="student_fees" class="badge rounded-pill"/>
            </div>
          </div>
          <div>
            <strong>School:</strong>
            <field name="school_id"/>
          </div>
        </t>
      </templates>
    </kanban>
  </field>
</record>

<record id="wb_student_action" model="ir.actions.act_window">
  <field name="name">Student</field>
  <field name="res_model">wb.student</field>
  <field name="view_mode">kanban,list,form</field>
  <field name="context">{'search_default_student_name': 1, 'search_default_gender_groupby':1}</field>
</record>

In this corrected version, you confirm that the tag structure is complete, attribute values follow the proper format, and the code aligns with updated Odoo 18 practices. Consequently, you eliminate common XML issues from previous versions.
