In a tree view inside a page, I need to show a column depending on a certain field. There is a transport field whose value can either be 'air' or 'ocean'. If 'air', I need to show the 'flight_no' column in the tree view, if it is 'ocean', I need to show 'voyage_no' instead.
Here is the current code snippet of the view, which is correct if it is ocean:
<page string="Routes">
<field name="freight_routes" nolabel="1" widget="one2many_list" context="{'shipper_id':shipper_id, 'consignee_id':consignee_id}">
<form>
<sheet>
...
<group>
<group>
<field name="transport" widget="radio" options="{'horizontal': true}"/>
</group>
<group>
</sheet>
</form>
<tree>
<field name="name" string="Carriage"/>
<field name="arrival_datetime"/>
<field name="voyage_no"/>
<field name="transport"/>
<field name="line_added" column_invisible="1"/>
<button name="action_insert_line_service" type="object" string="Add to Service" icon="fa-plus-square-o"/>
</tree>
</field>
</page>
I tried this but it did not work, maybe because transport is inside the form?
...
<tree>
<field name="name" string="Carriage"/>
<field name="arrival_datetime"/>
<field name="flight_no" column_invisible="transport != 'air'"/>
<field name="voyage_no" column_invisible="transport != 'ocean'"/>
<field name="transport"/>
<field name="line_added" column_invisible="1"/>
<button name="action_insert_line_service" type="object" string="Add to Service" icon="fa-plus-square-o"/>
</tree>
How should I fix this? Should I have 2 trees or 2 main field, each for air and ocean? How can I set-up the condition to display which tree?
