Hello,

I'm working on online quotation report customization, to display the products images on the quotation for the customer.

Everything is working just fine except of when the customer click on the quotation link sent by email, it directs him to the quotation but some of products images aren't loaded and it gives 404 forbidden error in the console. However if the customer logged in it will be displayed just fine.

Here's a sample of my code:


<template id="so_custom_quotation_content" inherit_id="website_quote.so_quotation_content" name="Custom Quotation">
        <xpath expr="//div[@class='oe_structure']" position="after">
            <section id="productdetails">
                <t t-foreach="quotation.order_lines_layouted()" t-as="page">
                    <table class="table table-condensed wq-table">
                        <thead>
                            <tr>
                                <th>Product</th>
                                <th></th>
                                <th></th>
                                <th>Description</th>
                            </tr>
                        </thead>
                        <tbody>
                            <t t-foreach="page" t-as="layout_category">
                                <t t-if="layout_category_size > 1 or page_size > 1" groups="sale.group_sale_layout">
                                    <tr class="active">
                                        <td colspan="7" style="font-weight: bold; border-bottom: 1px solid black;">&amp;bull;
                                            <t t-esc="layout_category['name']"/>
                                        </td>
                                    </tr>
                                    <tr></tr>
                                </t>
                                <t t-foreach="layout_category['lines']" t-as="line">
                                    <tr t-attf-class="product-description row-{{line_parity}}">
                                        <td style="padding:20px;" t-foreach="line.product_id" t-as="pro">
                                            <span t-field="pro.image_medium" t-field-options='{"widget": "image","class": "oe_avatar"}' style="padding:20px;"/>
                                        </td>
                                        <td></td>
                                        <td></td>
                                        <td class="colored">
                                            <p t-field="line.name"/>
                                        </td>
                                    </tr>
                                </t>
                            </t>
                        </tbody>
                    </table>
                    <t t-if="page_index &lt; page_size - 1" groups="sale.group_sale_layout">
                        <p style="page-break-before:always;"></p>
                    </t>
                </t>
            </section>
     </xpath>
</template>

The issue is stipulated by access rights of public users to products:

  1. When a user is not logged in, he/she is a "Public user"

  2. Public user has rights to read products (e.g.: look at the 'website_sale' addon, the rule 'access_product_product_public')

  3. Image_medium which you try to show is a computed fields with inverse, what requires more rights

The recommendations (alternatively):

  1. Redefine the functions to compute images, adding 'sudo'

  2. Add the special rights for public users via csv (may be not SAFE)

  3. Keep an image in another model.

Example of the last advise:

class avatar(models.Model):

    _name = 'avatar.avatar'

   

    image = fields.Binary(string='Image')

    product_id = fields.Many2one('product.product',string='Product')

class product_product(models.Model):

    _inherit = 'product.product'

   

    @api.one

    @api.depends('image_medium')

    def get_avatar(self):

        if self.avatar:

            self.avatar.image = self.image_medium

        else:

            avatar_id = self.env['avatar.avatar'].create({'product_id':self.id,'image': self.image_medium})

            self.avatar = avatar_id

   

    avatar = fields.Many2one('avatar.avatar',string="Avatar",compute="get_avatar",compute_sudo=True,store=True)

The rule for avatar:

access_avatar_avatar,access_avatar_avatar,model_avatar_avatar,,1,0,1,0

Afterwards, instead of image_medium in your template, use avatar.image

Well the presented solution helped me to overcome the 403 forbidden error. Now I'm facing another problem that the images are always cashed in the quotation table, no matter I try to remove or change the original product image, nothing changes in the online quotation. Any advice?
