Bonjour à tous,

Je travaille avec Odoo 17 et j'essaie de créer un filtre qui regroupe les enregistrements par write_date et stage_id . Cependant, je rencontre des problèmes de syntaxe dans la balise <filter> .

Lorsque j'essaie d'utiliser une liste dans l'attribut de contexte comme ceci :

xml
Modificateur de copieur
< filter 
    string = "État de la semaine" 
    name = "group_week_state" 
    context = "{'group_by': ['write_date', 'stage_id']}"
/>

Je reçois une erreur indiquant que l'attribut de contexte doit être une chaîne et non une liste Python.

Si j'essaie de le transmettre sous forme de chaîne séparée par des virgules à la place :

xml
Modificateur de copieur
< filter  
    string = "État de la semaine"  
    name = "group_week_state"  
    context = "{'group_by': 'write_date,stage_id'}" 
/>

Il applique uniquement le regroupement par write_date et ignore stage_id .

Quelqu'un a-t-il réussi à appliquer plusieurs champs group_by dans un seul filtre dans Odoo 17 ? J'apprécierais toute aide ou solution de contournement.

Merci d'avance!

Only known way to combine multiple fields in a predefined group_by is by defining a record for the ir.filters model.

This is also the only case in which Odoo combines two or more fields in a group_by in the UI by default that can be select by a user*. See for example https://github.com/odoo/odoo/blob/17.0/addons/account/report/account_invoice_report_view.xml#L61

To apply this approach, for example on the res.partner model, you would do the following:

view/res_partner_views.xml:

<?xml version="1.0" encoding="UTF-8" ?>
<odoo>
    <record id="filter_country_salesperson_group" model="ir.filters">
        <field name="name">By Country and Salesperson</field>
        <field name="model_id">res.partner</field>
        <field name="domain">[]</field>
        <field name="user_id" eval="False"/>
        <field name="context">{'group_by': ['country_id', 'user_id']}</field>
    </record>
</odoo>

Which would result in a filter stored as a favorite:

... and is essentially the same what Odoo does for example in the Invoicing App (technical name account):

A direct integration into the Group By-section does not seem to be possible.

If you want to prevent users from deleting (or changing) this particular filter (which could be easily done, since its a filter stored as a favorite just like any other) you could do a super().write() and super().unlink() extension checking for this particular record and raise an UserError when an attempt on changing or deleting is detected.

*) You can pass multiple pre-defined group_by filters when using a dedicated action, but according to your question and example source, this is not what you are looking for.

Hi,

In Odoo, the <filter> tag's context attribute must be a valid Python dictionary string, and the 'group_by' key can only accept a single field name (string), not a list of fields, even though Odoo's ORM supports grouping by multiple fields in backend code.

Try with any of the following.

1: Use the web UI (manual grouping)

Just advise your users to manually group by both fields using the “Group By” > “Add Custom Group” option in the search view. This is the safest option if you want to avoid custom modules.

2: Predefine a custom action (server-side context)

You can create a custom ir.actions.act_window that pre-sets multiple group_by fields using Python:

{

    'name': 'Group by Write Date and Stage',
    'type': 'ir.actions.act_window',
    'res_model': 'your.model',
    'view_mode': 'tree,form',
    'context': {
        'group_by': ['write_date', 'stage_id'],
    },
}

This works in server-side Python because the 'group_by' can be a list in that context.

Then link to this action from a menu item.

Hope it helps
