I am trying to get mail when a new record is created and modified for a field in CRM Module so I have defined these functions
in py:
#api.multi
def write (self, vals):
if 'lead_status' in vals and self.ids:
for rec in self:
template = self.env.ref ('crm_extended.crm_lead_mail_template')
template.send_mail (rec.id, force_send = True)
return super (crm_extended, self) .write (vals)
#api.multi
def create (self, vals):
if 'lead_status' in vals and self.ids:
for rec in self:
template = self.env.ref ('crm_extended.create_crm_lead_mail_template')
template.send_mail (rec.id, force_send = True)
return super (crm_extended, self) .write (vals)
when the change the state or give save, odoo popping me an error as below
Error:

you can not write #api.multi above the create method.
you have to use #api.model.

I'm using solution in the related answer for How to auto-dump modified values in nested dictionaries using ruamel.yaml, which uses the default (round-trip) loader/dumper.
I believe, it is a hard problem since additinal dict should keep comments as well.
=> Would it be possible to prevent comments to be removed if we use modify values in nested dictionaries using ruamel.yaml approach?
Example:
config.yaml:
c: # my comment
b:
f: 5
a:
z: 4
b: 4 # my comment
code (same code from How to auto-dump modified values in nested dictionaries using ruamel.yaml
), which changed to use the default (round-trip) loader/dumper:
#!/usr/bin/env python3
from pathlib import Path
from ruamel.yaml import YAML, representer
class SubConfig(dict):
def __init__(self, parent):
self.parent = parent

v = SubConfig(self)
v.update(value)
value = v

try:
res = super().__getitem__(key)

if self.filename.exists():

self.update(self.yaml.load(f) or {})
def updated(self):
if self.auto_dump:
self.dump(force=True)
else:
self.changed = True

if not self.changed and not force:

def update(self, *args, **kw):
for arg in args:
for k, v in arg.items():
self[k] = v
for k, v in kw.items():
self[k] = v
self.updated()
cfg = Config(Path("config.yaml"))
=> config.yaml file is updated as follows, where its comments are removed:
c:
b:
f: 5
a:
z: 4
b: 4
Yes, it is possible to prevent comments from being lost. The object returned from self.yaml.load() in your Config.__init__() method is not a dict, but a subclass thereof (ruamel.yaml.comments.CommentedMap) that includes all of the comment information (in its .ca attribute. And that CommentedMap will have values that are in itself again CommentedMap instances (at least with your input.
So what you need to do is change your classes:
class Config(ruamel.yaml.comments.CommentedMap):
and do the same for SubConfig. Then during the update routine you should try to copy the .ca attribute (it will be created empty on the CommentedMap, but not be available on {})
Make sure you all add a the representer for Config, and don't cast to dict in your Config.dump() method.
If you also copy the .fa attribute of the loaded data (also on Subconfig), you'll preserve the flow/block style of the original, and you can do a away with the self.yaml.default_flow_style = False.
The above is the theory, in practise there are a few more issues.
Your config.yaml changes, although you do not explicitly dump. That is
because your auto_dump is True by default. But that also means it
dumps for every change, i.e. your config.yaml gets dumped 10 (ten) times while the
Config/SubConfig data structure gets build.
I changed this to dump only once if auto_dump is True, but even that I would not
recommend, instead only dump if changed after loading.
A dict doesn't need initializing, but a CommentedMap does.
If you don't you get an attribute error at some point. So you'll have to
call super().__init__(self) in each the __init__ of each class.

print(Path(fn).read_text())
which gives:
c: # my comment
b:
f: 5
x: {g: 6}
a:
z: 4
b: 4 # my comment
Since the input changes, I write the config file to test out on every run.
I also added a flow style dict, to make clear that original formatting is performed.
When I am running server in django, getting this error:

It printed out this, but the error:
"'Player' object does not support indexing" pop out.
What is object does not support indexing error is?
And when I click the button, the oval does not actually move.
And using tkinter Button, I can call the method, right?
But by doing so, if I want to make for example, clicking the button, result to the oval moving to different location, how do I achieve that? Since as my code, above, the oval does not move eventhough the button is clicked.
Thanks. Since I'm quite new to python and programming, any help would be such a gratitude.
Indexing is when you suffix an object with [n], where n is an int. Here is how to reproduce the message.
>>> class C: pass
>>> C()[1]
Traceback (most recent call last):
File "<pyshell#21>", line 1, in <module>
C()[1]
TypeError: 'C' object does not support indexing
The File entry above the error message tells you the line number and expression that gave the error. Someplace in your code, as indicated by the traceback you did not show us, you have x[n], where x in an instance of the Player class you defined.
An object is subscriptable if and only if it has a __getitem__ method, which Player does not have and should not have.
my purpose is to display an different icon in treeview list when a specific postion(row, column) match a value. eg: (row, 2) is dir or file, will diplay different icon. because this is not used in local filesystem, QDir or Qfilesystem model not suite for this.
i know a bit on MVC that controller display in view, make model as data interface api. but i do not how to make it works on specific position(row ,col) as my expect.
i have tried to add args in ImageDelegate(like pass icon file name to it), but failed maybe due to its parent Class not accept more args.
hope someone can give me some light.
class ImageDelegate(QtGui.QStyledItemDelegate):
def __init__(self, parent=None):
QtGui.QStyledItemDelegate.__init__(self, parent)
#self.icon =icon
def paint(self, painter, option, index):
#painter.fillRect(option.rect, QtGui.QColor(191,222,185))
# path = "path\to\my\image.jpg"
path = "icon1.png"
image = QtGui.QImage(str(path))
pixmap = QtGui.QPixmap.fromImage(image)
pixmap.scaled(16, 16, QtCore.Qt.KeepAspectRatio)
painter.drawPixmap(option.rect.x(), option.rect.y(), pixmap)
and i can use this delegate in my view. but it will change all line in specific column.
def init_remotetreeview(self):
self.model = myModel(self.remote_Treeview)
for therow in range(self.model.rowCount(QModelIndex())) :
print self.model.data(self.model.index(therow, 2, QtCore.QModelIndex()),Qt.DisplayRole).toString() # i do check the value will used to load correct icon.
self.remote_Treeview.setItemDelegate(ImageDelegate(self)) # this change all lines
self.remote_Treeview.setModel(self.model)
In fact, your have some light in your code, isn't it ? (Just kidding.)
Your have right way to use QtGui.QStyledItemDelegate. I have reference how to implement it (But, C++ only). 'Star Delegate Example', 'QItemDelegate Class Reference C++' and 'QItemDelegate Class Reference PyQt4';
