Hi guys,

I've been trying to create a function to send out HTML e-mails but I always run stuck.
I first created a new model 'odoo.environment.email' which will be the older for my e-mail templates like this:

# -*- coding: utf-8 -*-
from openerp import models, fields, api, _
from openerp.exceptions import Warning
class odoo_environment_emails(models.Model):
    _name = 'odoo.environment.email'
    name = fields.Char('E-mail name', required=True)
    email = fields.Char('E-mailadress primary person', required=True)
    email_cc = fields.Char('Emailadress CC persons')
    email_title = fields.Char('E-mail title', required=True)
    message = fields.Html('Message', required=True)

I then created a custom template in XML which contains HTML content:

<openerp>
    <data noupdate="1">
        <record id="odoo_email_installation" model="odoo.environment.email">
            <field name="name">Title</field>
	    <field name="email">example@example.com</field>
	    <field name="email_cc">example2@example.com</field>
	    <field name="email_title">New record(${object.odoo_username}) created!</field>	    <field name="message"><![CDATA[
		<p>My custom text: ${object.name}</p>
            </field>        
        </record>
    </data>
</openerp>

On another model 'odoo.environment' I've created a Many2many where you can add all the e-mail templates you like, which are created on the model 'odoo.environment.email':

odoo_emails_to_send = fields.Many2many('odoo.environment.email', string='E-mails to send after installation', default=_get_default_emails)

Now I have a Python function that is triggered when the user clicks on a function. This function will loop over all items added in the Many2many and every e-mail template added should throw out an own e-mail. What I have now:

    def send_required_mails(self, cr, uid, ids, record, context=None):
	# Get e-mail server
	ir_mail_server = self.pool.get('ir.mail_server')
	# Get all selected e-mail templates
	email_template_ids = record.odoo_emails_to_send
	# Send out one template at a time
	for email_id in email_template_ids:
	    email_template = self.pool.get('odoo.environment.email').browse(cr, uid, email_id.id)
	    title = email_template.email_title
	    message = email_template.message
	    msg = ir_mail_server.build_email('from@email.com', [email_template.email], title, message, [email_template.email_cc or ''], [], 'reply_to@email.com')
	    ir_mail_server.send_email(cr, uid, msg

This works pretty nice but I have 1 problem: the HTML is not rendered and all ${object.variable} are not filled / converted. I've read some posts and it seems to be that I need to send the e-mail out with generate_email, so I tried:

    def send_required_mails(self, cr, uid, ids, record, context=None):
	# Send out one template at a time
	for email_id in email_template_ids:
	    template_id = self.pool.get('ir.model.data').get_object(cr, uid, 'auto_odoo_installer', 'odoo_email_installation').id
	    template_ids = self.pool.get('odoo.environment.email').browse(cr, uid, template_id)
            email_template_obj = self.pool.get('email.template')
    	    if template_ids:
          	values = email_template_obj.generate_email(cr, uid, template_ids[0], ids, context=context)
         	values['subject'] = subject 
          	values['email_to'] = email_to
          	values['body_html'] = body_html
          	values['body'] = body_html
          	values['res_id'] = False
          	mail_mail_obj = self.pool.get('mail.mail')
          	msg_id = mail_mail_obj.create(cr, uid, values, context=context)
                if msg_id:
                    mail_mail_obj.send(cr, uid, [msg_id], context=context) 
        return True

However this keeps throwing up errors. For example:

  File "/odoo/odoo-server/openerp/api.py", line 256, in wrapper
    return old_api(self, *args, **kwargs)
  File "/odoo/odoo-server/addons/email_template/email_template.py", line 219, in get_email_template_batch
    results = dict.fromkeys(res_ids, False)
TypeError: unhashable type: 'list

So, how should I correctly send out these e-mails and get the HTML and ${object.variable} converted to plain text in the e-mail?

Thanks,
Yenthe
