Odoo Wizard writes to model but getting values from models doesn`t doesnt populate the wizard fields - odoo

Question

I have a wizard below that writes to the database but doesnt read the values written to the database and display in the view.
I using the get_opinion to read the opinions and the get_notes to read the notes , but when i click on the buttons they just disappear with no error , where am i going wrong
Q2 , in this code which is part of the code below why am i getting model_name none
if context is None: context = {}
model_name=context.get('active_model')
print model_name #gives NONE why ?
Q3 How can i list all fields in context?
The module code is as below
class opinion(models.TransientModel):
_name='opinion'
opinion_emission = fields.Text(string='OPINION EMISSION')
notes = fields.Text(string='Additional Notes')
defaults={
'opinion_emission': lambda self : self.get_opinion(self),
'notes': lambda self : self.get_notes(self),
}
def save_it(self, cr, uid,ids , context=None):
# context = dict(self._context or {} )
if context is None: context = {}
active_id = context.get('active_id',False)
print 'active_id' , active_id
if active_id :
# op = self.env['opinion'].browse(active_id)
info = self.browse(cr,uid,ids)
self.pool.get('opinion').write(cr,uid,context['active_id'],{'opinion_emission': info[0].opinion_emission,'notes': info[0].notes})
return {
'type': 'ir.actions.act_window_close',
}
#functions that get the info stored in db
#api.one
def get_opinion(self):
ids=self._ids
cr = self._cr
uid = self._uid
context = self._context
if context is None: context = {}
active_id = context.get('active_id',False)
print 'active_id' , active_id
if active_id :
return self.env['opinion'].browse(cr, uid, context['active_id'], context).opinion_emission
#api.one
def get_notes(self,records=None):
ids=self._ids
cr = self._cr
uid = self._uid
context = self._context
if context is None: context = {}
model_name=context.get('active_model')
print model_name #gives NONE why ?
active_id = context.get('active_id',False)
print 'active_id' , active_id
if active_id :
print 'output',self.env['opinion'].browse(cr, uid, context['active_id'], context)[0].notes
return self.env['opinion'].browse(cr, uid, context['active_id'], context)[0].notes
The xml view code is :
<openerp>
<data>
<record id="view_opinion_wizard" model="ir.ui.view">
<field name="name">opinion_wizard.form</field>
<field name="model">opinion</field>
<field name="type">form</field>
<field name="arch" type="xml">
<!-- create a normal form view, with the fields you've created on your python file -->
<form string="OPINION" version="8.0">
<button icon="gtk-ok" name="get_notes" string='SET VAL' type="object" />
<group >
<separator string="Please insert OPINION" colspan="2"/>
<field name="opinion_emission" string="OPINION EMISSION "/>
<field name="notes" string="NOTES"/>
<newline/>
</group>
<div style="text-align:right">

<button icon="gtk-ok" name="get_notes" string="GET NOTES" type="object" />
<button icon="gtk-ok" name="get_opinion" string="GET OPINION" type="object" />
</div>
</form>
</field>
</record>
<!-- your action window refers to the view_id you've just created -->
<record id="action_opinion" model="ir.actions.act_window">
<field name="name">OPINION</field>
<field name="type">ir.actions.act_window</field>
<field name="res_model">opinion</field>
<field name="view_type">form</field>
<field name="view_mode">form</field>
<field name="view_id" ref="view_opinion_wizard"/>
<field name="target">new</field>
</record>
<menuitem name="OPINION" id="menu_opinion" action="action_opinion" parent="timeorder_ratecard_rnd_menu"/>

Answer 1

This is new API code try this code:
class opinion(models.TransientModel):
_name = 'opinion'
opinion_emission = fields.Text(default=lambda self: self.get_opinion(self), string='OPINION EMISSION')
notes = fields.Text(default=lambda self: self.get_notes(self), string='Additional Notes')
#api.multi
def save_it(self):
active_id = self.env.context.get('active_id', False)
print 'active_id', active_id
if active_id:
op = self.env['opinion'].browse(active_id)
op.write({'opinion_emission': self.opinion_emission, 'notes': self.notes})
return {'type': 'ir.actions.act_window_close', }
#functions that get the info stored in db
#api.one
def get_opinion(self):
active_id = self.env.context.get('active_id', False)
print 'active_id', active_id
if active_id:
return self.env['opinion'].browse(active_id).opinion_emission
#api.one
def get_notes(self, records=None):
model_name = self.env.context.get('active_model')
print model_name # gives NONE why ?
active_id = self.env.context.get('active_id', False)
print 'active_id', active_id
if active_id:
print 'output', self.env['opinion'].browse(active_id).notes
return self.env['opinion'].browse(active_id).notes
