Odoo v8 custom model with workflow error

I am currently working on a school project with Odoo v8 with custom models and workflows. For each state of the workflow I want to execute python code, but recently I got the following error. I have used the following website: https://www.odoo.com/nl_NL/forum/help-1/question/how-to-move-around-workflow-states-back-and-forth-21509

  File "/usr/lib/python2.7/dist-packages/openerp/tools/safe_eval.py", line 314, in safe_eval
    return eval(c, globals_dict, locals_dict)
  File "", line 1, in <module>
ValueError: "name 'action_draft' is not defined" while evaluating
u'action_draft()'

Model:

from openerp import models, fields, api, _
from openerp.exceptions import Warning class child(models.Model):
 _name = 'xmi2odoo.child'
    _description = 'child'
    _states_ = [
        # State machine: untitle
        ('draft', 'Draft'),
        ('submitted', 'Submitted'),
        ('confirmed', 'Confirmed'),
        ('cancelled', 'Cancelled'),
    ]
    name = fields.Char(
        string='name'
        )
    state = fields.Selection(
        _states_,
        'State',
        default='draft',
        )
    parents = fields.Many2many(
        'xmi2odoo.person',
        'xmi2odoo_parents_parentoff_rel',
        'child_id',
        'person_id',
        string='parents'
        )

I like to surround myself with brave, creative people.

My motivation for learning different technologies and algos drive me. I love challenges of a steep learning curve which I believe makes me a better learner. I have a strong desire to learn different technologies, which would enable me to become a full stack developer.

I have checked  your code ,i find the problem in indentation  , so just correct the indentation of your code , it will work

class child(models.Model):

_name = 'xmi2odoo.child'

_description = 'child'

_states_ = [

# State machine: untitle

('draft', 'Draft'),

('submitted', 'Submitted'),

('confirmed', 'Confirmed'),

('cancelled', 'Cancelled'),

]

name = fields.Char(

string='name'

)

state = fields.Selection(

_states_,

'State',

default='draft',

)

# parents = fields.Many2many(

# 'xmi2odoo.person',

# 'xmi2odoo_parents_parentoff_rel',

# 'child_id',

# 'person_id',

# string='parents'

# )

@api.multi

def action_cancelled(self):

res = self.write({'state': 'cancelled'})

return res

@api.multi

def action_confirmed(self):

res = self.write({'state': 'confirmed'})

return res

@api.multi

def action_draft(self):

res = self.write({'state': 'draft'})

return res

@api.multi

def action_submitted(self):

res = self.write({'state': 'submitted'})

return res



In your code you have put these method (action_cancelled,action_confirmed,action_draft,action_submitted) at the class level .

In python the namespace define by the indentation  .

Wow I was totally looking in the wrong direction. It's working now, thanks Sharma!
