Struggle to insert wizard in Party module (overriding)

Still cannot inject my Wizard into Party Module.
I created a party.py in my custom module.
Added the following wizard in it:

## ——————— WIZARD TO LOAD PARTIES ———————————
class ImportStatementStart(ModelView):
    "Party Import Start"
    __name__ = 'party.party.import.start'
    file_ = fields.Binary("File", required=True)
    file_format = fields.Selection([(None, '')], 'File Format', required=True)

    @classmethod
    def default_file_format(cls):
        return 'CSV'

class ImportStatement(Wizard):
    "Party Import"
    __name__ = 'party.party.import'
    start = StateView('party.party.import.start',
        'party.party.import_party_form', [
            Button("Cancel", 'end', 'tryton-cancel'),
            Button("Import", 'import_', 'tryton-ok', default=True),
            ])
    import_ = StateAction('party.party')

    def do_import_(self, action):
        pool = Pool()
        Statement = pool.get('party.party')
        ###  HERE SOME IMPORT ACTIONS ####
        return action, data

I am adding the following lines in party.xml in my module folder:

    <!-- ########################################## -->
    <!-- # Action for importing parties from file # -->
    <!-- ########################################## -->
        <!-- An action: load parties from file  -->
        <record model="ir.action.wizard" id="wizard_parties_import">
            <field name="name">Import parties</field>
            <field name="wiz_name">party.party.import</field>
            <field name="model">party.party.import.start</field>
        </record>
        <!-- ADD an action ITEM in the list of actions: Import parties -->
        <record model="ir.action.keyword" id="act_wizard_parties_import">
            <field name="keyword">form_action</field>
            <field name="model">party.party,-1</field>
            <field name="action" ref="wizard_parties_import"/>
        </record>
        <!-- ADD an wizard view to get additional data from user-->
        <record model="ir.ui.view" id="import_party_form">
            <field name="model">party.party.import.start</field>
            <field name="type">form</field>
            <!-- form view file in ./view/import_party_form.xml -->
            <field name="name">import_party_form</field>
        </record>
        <!-- Add a menu item to Tryton with this action-->
        <menuitem parent="party.menu_party" sequence="20"
            action="wizard_parties_import" id="menu_party_import"/>

And still, get the errors:

ERROR:trytond.convert:Error while parsing xml file:
In tag record model ir.action.keyword with id fleets.act_wizard_parties_import

trytond.ir.action.WizardModelError: Wrong wizard model in keyword action "Import parties". - 

trytond.ir.action.WizardModelError: Wrong wizard model in keyword action "Import parties". -

Where I can see the working example of wizard overriding??
(I added couple of wizards to my own module without problems)

Did you declare all (wizard, model) in your __init__.py file ?

Your problem is in the model field of the wizard:

The model is used to limit on which models the wizard should be abailable. I see you set here the start model but this is not aplicable as this is the start model of the wizard.

Setting the field to blank should fix the issue.

Unbelievable!
Yes that’s work!

I didn’t expect that would be possible to omit the model. Didn’t tried that!
Thanks!

Constantine.
PS: I still thinking that is worth having more complex examples for “case studies” with detailed comments. Like I asked about 3-rd party SMTP option, modules overriding, wizard views etc… I would be happy to share my findings.

Sure thing, that is an important part, that also not clearly discussed in docs, although it is pretty evident.

When I call my Wizard from the client — I receive this runtime error:

Traceback (most recent call last):
  File "/trytond/wsgi.py", line 109, in dispatch_request
    return endpoint(request, **request.view_args)
  File "/trytond/protocols/dispatcher.py", line 48, in rpc
.....
    view_id = ModelData.get_id(module, fs_id)
  File "/trytond/ir/model.py", line 1239, in get_id
    % ".".join([module, fs_id]))
KeyError: 'Reference to party.import_party_form not found'

Here the description in party.xml
it actually loads with trytond-admin.

# /modules/mymodule/party.xml
        <!-- ADD an wizard view to get additional data from user-->
        <record model="ir.ui.view" id="import_party_form">
            <field name="model">party.party.import.start</field>
            <field name="type">form</field>
            <!-- form view file in ./view/import_party_form.xml -->
            <field name="name">import_party_form</field>
        </record>
        <!-- Add a menu item to Tryton with this action-->
        <menuitem parent="party.menu_party" sequence="20"
            action="wizard_parties_import" id="menu_party_import"/>

What happens actually? I cannot understand the error report.

Added more detailed reporting:

  File "/trytond/ir/model.py", line 1240, in get_id
    ".".join([module, fs_id]),
KeyError: "Reference ('party', 'import_party_form') to party.import_party_form not found"

Found an error. So silly!

As the report view is kept in …/mymodule/view/…
hence the header of Wizard should look like:

class ImportStatement(Wizard):
    "Party Import"
    __name__ = 'party.party.import'
    start = StateView('party.party.import.start',
##### ——— !!!!!! Here should be an ACTUAL path to report !!!!!! —————
            'mymodule.import_party_form', [
            Button("Cancel", 'end', 'tryton-cancel'),
            Button("Import", 'import_', 'tryton-ok', default=True),
            ])
    import_ = StateAction('party.act_party_form')

and still the report description is in ../mymodule/party.xml
