hello sir thanks for replying you are really a teacher for me :D Just one question how would you check if the value of o.per_diem which you printed in the first line is repeating itself or not

Repeating means? Its in a loop <t t-foreach="docs" t-as="o"> print it in the foreach loop or outside.

Use if like <span t-field="o.per_diem" />

<t t-if="o.per_diem>100">

<span t-field="o.city" />

</t>

Sir i have tree view as you know i select lines and print them and it shows me the comparison of different prices quoted by the vendor for different products. But for each product vendor name prints itself again. I want to see in the selected lines that if vendor's name is same as before then it must not print again

You need group by vendor.. here is an example

https://www.odoo.com/forum/help-1/question/how-to-group-by-product-category-in-qweb-report-102920

Thank you sir i will try and let you know in a moment. You are always a big help

sir this is giving me this error " 'str' object has no attribute 'vendor'"

i am using following code as you have suggested

<t t-set="vendor_list" t-value="[]"/>

<t t-foreach="docs" t-as="o">

<t t-set="vendor_list" t-value="vendor_list+[o.vendor]"/>

</t>

<t t-foreach="set(vendor_list)" t-as="category">

<div><strong t-esc="category.vendor"/></div>

<t t-foreach="docs" t-as="o">

<t t-if="category.vendor==o.vendor">

<div><span t-field="o.vendor"/></div>

</t>

</t>

</t>

Please dont get irritated as i am bothering you again and again but kindly help me for this last time

Share your custom model code here...what fields it has. What is relation with res_partner?

i am fetching data from the data base so i have made partner too as a Char field

class PostgresReport(models.Model):

_name = 'purchase.comp'

_auto = False

name = fields.Char(string = 'Purchase Order')

origin = fields.Char(string ='Purchase Agreement')

date_order = fields.Datetime('Order Date', index=True, copy=False)

state = fields.Selection([

('draft', 'RFQ'),

('sent', 'RFQ Sent'),

('to approve', 'To Approve'),

('purchase', 'Purchase Order'),

('done', 'Locked'),

('cancel', 'Cancelled')

], string='Status', readonly=True, index=True, copy=False, default='draft', track_visibility='onchange')

requisition_id = fields.Char(string='requisition_id')

product_id = fields.Char(string='Product')

product_qty = fields.Float(string='Quantity')

price_unit = fields.Float(string='Unit Price')

price_subtotal = fields.Float(string='Subtotal')

vendor = fields.Char(string='Vendor')

currency_id = fields.Char('Currency')

@api.model_cr

def init(self, _logger=None):

""" Event Question main report """

query = []

tools.drop_view_if_exists(self._cr, 'purchase_comp')

view = self._cr.execute(""" CREATE VIEW purchase_comp AS (

SELECT

b.id as id,

a.name as "name",

a.state as "state",

b.name as "product_id",

b.order_id as "order_id",

public.purchase_order_line as b

on a.id = b.order_id

inner join

public.res_partner as c

on a.partner_id = c.id

inner join

public.res_currency as d

on d.id = b.currency_id

WHERE a.origin != ''

order by a.name

)""")

The code you shared is for Odoo Business Intelligence where you select measures and analyze data, like lot of odoo standard reports. But the report that you are trying to develop is a simple PDF report.

so i cannot group it by vendor in qweb? Not possible?

Try to group by in your above sql query like order by vendor.... Test your sql query in postgresql to get your required results.

sir i have tried that all and i am able to remove duplicates from the report by using this

<t t-set="product_names" t-value="[]"/>

<t t-foreach="docs" t-as="o">

<t t-set="product_names" t-value="product_names+[o.product_id]"/>

</t>

<t t-foreach="set(product_names)" t-as="bat">

<tr class="row2">

<td>

<span t-field="bat.id" />

<span t-field="bat.name" />

</td>

</tr>

</t>

But this code works for Many2one field only and i have float fields as well so m at a dead end now.

sir can you tell what this means?

sale_order_id = request.session.get('sale_last_order_id')

i found this is website_sale module in controller.

I also have a report made from controller which opens in website. If i somehow able to download it in pdf my work will be done. if you know any work around for downloading pdf from website
