Hello, I asked on this forum how to put 2 actions for 1 menuitem but someone answers that I don't need to put 2 actions for 1 menuitem but I've to return the tree view in my python function which is called in my action server in my XML file.


This is my python code :

class miadi_poidsConditionnement(models.Model):

    _name = 'miadi.poidsconditionnement'

    # _order = 'conditionnement_id asc'

    conditionnement_id = fields.Many2one('miadi.packaging', 'Packaging', default='', required=True)

    produit_id = fields.Many2one('product.product', 'Product', default='', required=True)

    nb_articles = fields.Integer(string='Number of products', default=0)

    poids = fields.Float(string='Packaging Weight', default=0)

    _sql_constraints = [

    ('uniq_id', 'unique(produit_id, conditionnement_id)', 'A product already exists with this packaging !'),

    ]

    @api.multi

    @api.model

    def chargement_ratio(self):

        productRatio = self.env['miadi.poidsconditionnement']

        conditionnements = self._cr.execute("SELECT id FROM miadi_packaging")

        query_cond = self.env.cr.dictfetchall()

        produits = self._cr.execute("SELECT id FROM product_product")

        query_prod = self.env.cr.dictfetchall()

        for conditionnements in query_cond:

            nom_conditionnement = conditionnements['id']

            for produits in query_prod:

                product = produits['id']

                if_exist = self._cr.execute("SELECT * FROM miadi_poidsConditionnement WHERE conditionnement_id=%s AND produit_id=%s", (nom_conditionnement, product))

                if not if_exist:

                    Ratio = productRatio.create({'conditionnement_id': nom_conditionnement, 'produit_id': product})

                    return {'type': 'ir.actions.act_window', 'view_type': 'tree', 'view_mode': 'tree', 'res_model': 'miadi.poidsconditionnement', 'res_id': miadi.poidsconditionnement.id, 'view_id': self.env.ref('action_miadi_poidsConditionnement').id, 'target': 'current',}


And this is my XML :

<?xml version="1.0" encoding="utf-8"?>

<openerp>

 <data>

  <record id="miadi_poidsConditionnement_form" model="ir.ui.view">

   <field name="name">miadi.poidsconditionnement.form</field>

   <field name="model">miadi.poidsconditionnement</field>

   <field name="arch" type="xml">

    <form string="Weight/number ratio">

     <group col="4">

      <field name="produit_id" widget="selection" eval="ref('product.product.attribute_value_ids')" />

      <!-- <field name="produit_id" /> -->

      <field name="conditionnement_id" widget="selection" eval="ref('miadi.packaging.conditionnement_id')" />

      <!-- <field name="conditionnement_id" /> -->

      <field name="nb_articles" />

      <field name="poids" />

     </group>

    </form>

   </field>

  </record>

  <record id="miadi_poidsConditionnement_tree" model="ir.ui.view">

   <field name="name">miadi.poidsconditionnement.tree</field>

   <field name="model">miadi.poidsconditionnement</field>

   <field name="arch" type="xml">

    <tree string="Weight/number ratio">

     <field name="produit_id" ref="product.product.attribute_value_ids" />

     <field name="conditionnement_id" ref="miadi.packaging.conditionnement_id" />

     <field name="nb_articles" />

     <field name="poids" />

    </tree>

   </field>

  </record>

  <record model="ir.ui.view" id="miadi_poidsConditionnement_search">

   <field name="name">miadi.poidsconditionnement.search</field>

   <field name="model">miadi.poidsconditionnement</field>

   <field name="arch" type="xml">

    <search string="Weight/number ratio">

     <field name="produit_id" />

     <group expand="0" string="Group by">

      <filter string="Product" domain="[]" context="{'group_by':'produit_id'}"/>

      <filter string="Packaging" domain="[]" context="{'group_by':'conditionnement_id'}"/>

     </group>

    </search>

   </field>

  </record>

  <record model="ir.actions.act_window" id="action_miadi_poidsConditionnement">

   <field name="name">Weight/number ratio</field>

   <field name="type">ir.actions.act_window</field>

   <field name="res_model">miadi.poidsconditionnement</field>

   <field name="view_type">form</field>

   <field name="view_mode">tree,form</field>

   <field name="view_id" ref="miadi_poidsConditionnement_tree"/>

   <field name="help" type="html">

    <p class="oe_view_nocontent_create">Click here to create a weight/number ratio.</p>

   </field>

  </record>

  <record id="action_chargement_ratio" model="ir.actions.server">

   <field name="name">Chargement Ratio</field>

   <field name="res_model">action_miadi_poidsConditionnement</field>

   <field name="type">ir.actions.server</field>

   <field name="model_id" ref="model_miadi_poidsconditionnement"/>

   <field name="code">chargementRatio = env['miadi.poidsconditionnement'].browse(context.get('active_id'));chargementRatio.chargement_ratio()</field>

  </record>

  <menuitem name="Weight/number ratio" id="menu_miadi_poidsConditionnement" parent="menu_miadi_packaging" sequence="15" groups="sales_team.group_sale_manager" action="action_chargement_ratio" />

 </data>

</openerp>


And it gives me an issue :

ValueError: <type 'exceptions.NameError'>: "global name 'miadi' is not defined" while evaluating
u"chargementRatio = env['miadi.poidsconditionnement'].browse(context.get('active_id'));chargementRatio.chargement_ratio()"


I want to return the tree view (action_miadi_packaging) and I want my python function is called when I click on the menuitem

How can I resolve this issue ?


And if I write "'res_id': productRatio.id" (where productRatio = self.env['miadi.poidsconditionnement']), instead of "'res_id': miadi.poidsconditionnement.id" the error is :

ValueError: <type 'exceptions.ValueError'>: "need more than 1 value to unpack" while evaluating
u"chargementRatio = env['miadi.poidsconditionnement'].browse(context.get('active_id'));chargementRatio.chargement_ratio()"

Thanks for answers

Hi Miadi,

You can return a view from python code like this, you have to mention the correct view id

return {
'name': _('test'),
'view_type': 'tree',
'view_mode': 'tree',
'view_id': self.env.ref('account.invoice_tree').id,
'res_model': 'account.invoice',
'context': "{'type':'out_invoice'}",
'type': 'ir.actions.act_window',
'target': 'new',
}

Hi Niyas,

my view_id is correct (if you look my XML code and my Python code, you can see that the view id is correct

I update my code with your answer and it's works, my tree view is display BUT, what I put in my code before the return doesn't happen...

MIADI

No, finally it doesn't works, it gives me this issue : ValueError: <type 'exceptions.NameError'>: "global name '_' is not defined" while evaluating

u"chargementRatio = env['miadi.poidsconditionnement'];chargementRatio.chargement_ratio()"

MIADI

and if I remove 'name': _('test'), the view is not display

I wrote this :

return {

'name': _('test'),

'view_type': 'tree',

'view_mode': 'tree',

'view_id': self.env.ref('miadi_packaging.miadi_poidsConditionnement_tree').id,

'res_model': 'miadi.poidsconditionnement',

'type': 'ir.actions.act_window',

'target': 'new',

}

It should work no ?

In the action of the menuitem, I've to put the server action id no ?

If yes, it should work but my tree view is not display...

Can you help me ?

MIADI

Looking at my codes, can you tell me if my view_id is good ? Because nothing happens when I click on the menu

MIADI

I fix the problem, the error was in my XLM code

But the result is not really that I want...

When I click on the menuitem, I have a popup^with the tree view but I can't modify the records and what I really want is to have a tree view but not in a popup, I want a "normal" tree view

Hai Miadi, A simplecorrection , not XLM code its XML code

Hi,

It works and I have a treeview but it's not the tree view that I want because I've a tree view in a popup (and I can't chage any record) and what I want is a "normal" tree view

What I have : https://www.hostingpics.net/viewer.php?id=358419Capturetreeview.png


What I want : https://www.hostingpics.net/viewer.php?id=947270Capturetreeview2.png


Or I want to be able to modify some fields in this popup treeview. Is it possible ? If yes, how can I do it ?


If someone can help me, it will be very good
