Odoo 10 Go to purchase list from custom model

Question

I am pulling data from an external source like this:

from odoo import models,fields,api
import datetime
import requests
import logging
_logger = logging.getLogger(__name__)
class purchase_order(models.Model):

_inherit = "purchase.order"


@api.model
def getOrdersTechData(self):

     getServer = 'someapi.xxx'

     get_response = requests.get(url=getServer).json()
     partner_id = get_response['partner_id']
     name = get_response['name']
     product_id = get_response['product_id']
     ...

     self.createBestelAanvraag(partner_id,name,product_id,product_qty,product_uom,price_unit,date_planned)


@api.multi
def createBestelAanvraag(self,partner_id,name,product_id,product_qty,product_uom,price_unit,date_planned):
     _logger.debug("name:")
     _logger.debug(name)
     self.PurchaseOrder = self.env['purchase.order']
     po_vals = {
        'partner_id': partner_id,
        'order_line': [
            (0, 0, {
                'name': name,
                ...
            }),
           ],
    }


     self.po = self.PurchaseOrder.create(po_vals)

I initatiate this from a menuitem on the home screen like this:

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

<odoo>
    <data>
        <record id="action_make_testing" model="ir.actions.server">
            <field name="name">My Action</field>
            <field name="model_id" ref="model_purchase_order"/>
            <field name="code">env['purchase.order'].getOrdersTechData()
            </field>
        </record>

        <menuitem name="Fetch Data" action="action_make_testing" 
              id="sale_order_custom_document"  sequence="20"/>    
    </data>
</odoo>

But after the order is created, I see a blank view and I have to go to purchases from the GUI. Instead, I would like to see the purchase list view with all orders including the new one immediately.

I've modified some things in your code. You must return another action from Python to open the tree view:

Python code

@api.model
def getOrdersTechData(self):
    getServer = 'someapi.xxx'
    get_response = requests.get(url=getServer).json()
    partner_id = get_response['partner_id']
    name = get_response['name']
    product_id = get_response['product_id']
    ...
    po = self.createBestelAanvraag(partner_id,name,product_id,product_qty,product_uom
    res = {
        'view_type': 'form',
        'view_mode': 'tree',
        'res_model': 'purchase.order',
        'type': 'ir.actions.act_window',
        'target': 'current',
    }
    return res

@api.model
def createBestelAanvraag(self, partner_id, name, product_id, product_qty,
                         product_uom, price_unit, date_planned):
    po_vals = {
        'partner_id': partner_id,
        'order_line': [
            (0, 0, {
                'name': name,
                ...
            }),
        ],
    }
    return self.env['purchase.order'].create(po_vals)

XML code

<record id="action_make_testing" model="ir.actions.server">
    <field name="name">My Action</field>
    <field name="condition">True</field>
    <field name="type">ir.actions.server</field>
    <field name="model_id" ref="model_purchase_order"/>
    <field name="state">code</field>
    <field name="code">env['purchase.order'].getOrdersTechData()</field>
</record>

NOTE 1

If you see the purchase tree view but your purchase order is not there yet, add auto_refresh parameter to the res value:

res = {
    'view_type': 'form',
    'view_mode': 'tree',
    'res_model': 'purchase.order',
    'type': 'ir.actions.act_window',
    'target': 'current',
    'auto_refresh': 1,
}
return res

NOTE 2

If instead of the tree view of purchase order you wanted to see the purchase order you have just created, change the res variable this way (in the above Python code I wrote you):

res = {
    'view_type': 'form',
    'view_mode': 'form',
    'res_model': 'purchase.order',
    'res_id': po.id,
    'type': 'ir.actions.act_window',
    'target': 'current',
}
return res

Answer 2

You can return an action for purchase.

Try this:

 action = self.env.ref('purchase.purchase_rfq').read()[0]
 action.update({'domain': [('id', '=', self.po.id)], 'res_id': self.po.id})
 return action

This will open the purchase views and will show the purchase orders.
