Trying to send mails from website

Hi guys,

 

I am using Celery and Eventlet to facilitate a task which sends emails.  I am using the following code:

 

@task

def order_created(order_id):

    """

    Task to send an e-mail notification when an order is

    successfully created.

    """

    order = Order.objects.get(id=order_id)

    subject = 'Order nr. {}'.format(order.id)

    message = 'Dear {},\n\nYou have successfully placed an order.\

                    Your order id is {}.'.format(order.first_name,

                                                 order.id)

    mail_sent = send_mail(subject,message,settings.EMAIL_HOST_USER,[order.email],fail_silently=False)

   

 

    return mail_sent

 

I get the following error

 

TypeError: wrap_socket() got an unexpected keyword argument '_context'

 

Can anyone assist?

I am using Python 3.8

Celery 4.4.2

Eventlet 0.25.2

Django 2.2.12

 

 

Sent from Mail for Windows 10

Hi Amit,

thanks for your response. But in this way, I can't use the sphinx templates, the links are not correct and after every new make html (or using sphinx-autobuild) I have to copy the changed or new files. Are there no more likable way?

Hii 

If u want to just add your file in your django project u can probably copy and paste the file in your project file and after that you can successfully use your file in the project by just writing the name of  your file with correct extension

Hi,

I installed sphinx and I get an documentation in
project_main/docs/_build/html, starting with html/index.html. In so far
- fine.

Now I want to present this documents inside my project so I can see in
the nav-bar a "doc" where I can see them. But I have no idea how to
start it. I tried it with a simple function in a view inside an app, but
then I need a symbolic-link for getting the index.html, but then I can't
get the rest of the documentation.

I tried to google it but I only find tutorials for using sphinx to make
a documentation for the django-project but I didn't find a tip how I can
realize it.

Could anyone give a kick-off for it or a link for a tutorial? Perhaps I
have only the wrong keywords..

Some thoughts.

You are collecting all the output from stdout into the out object
returned from the the subprocess run() function.

That means the run function is buffering stdout before returning from
the call. I haven't been able to find a limit on the buffer size (which
could explain why it never returns), but even if there is no limit, you
most likely want to return the output in chunks to improve user
experience and limit memory usage.

Try to look at popen and use that instead:

https://docs.python.org/3/library/subprocess.html

The strange output is caused by combining the output from stdout and
stderr. You almost certainly don't want to return output from stderr to
the user, but consider that an error/exception and handle that
internally. The popen object should help you with that. If the script
you are calling is well written, it will return a non-successful return
code (ie. not 0) on errors which should cause an exception you can handle.

Finally, you are passing user input directly from the user (the "param"
POST value) to the script. As long as you don't execute it through the
shell, it is probably not much of a security issue, but be careful and
assume that the inp variable could contain anything and is not under
your control.

Hope that can help you in the right direction. I don't have any complete
solution, but that's what I would look into.

Kind regards,

Kasper Laudrup

Re: How to use ModelChoiceField? I whould like to filter the output from a field form.

А не могли бы вы подсказать как вызвать две разные формы, от двух разных классов в models.py, на одной странице?

Нужно передать в контекст views.py две формы, и эти две формы по разному назвать.

class SkladCreateView(LoginRequiredMixin, CustomSuccessMessageMixin, CreateView):

    model = Sklad

    template_name = 'sklad.html'

    form_class = SkladForm

    success_url = reverse_lazy('sklad')

    success_msg = 'Материал сохранён'

    def get_context_data(self, **kwargs):

        kwargs['list_sklad'] = Sklad.objects.all().order_by('material')

        return super().get_context_data(**kwargs)

    # это функция для назначения автора

    def form_valid(self, form):

        self.object = form.save(commit=False)

        self.object.author = self.request.user

        self.object.save()

        return super().form_valid(form)

Кажется я понял, вы влепили два init в класс? А зачем...

    def __init__(self, *args, **kwargs):

        # get 'user' param from kwargs

        user = kwargs.pop('user', None)
        super().__init__(*args, **kwargs)

        # set class attrs  

        for field in self.fields.values():

             field.widget.attrs['class'] = 'form-control'

        # set 'name_job' queryset

        self.fields['name_job'].queryset = TypJob.objects.filter(author__id=user.id)

Не совсем понимаю, это init какого класса...Но можно попробовать так:
    def __init__(self, *args, **kwargs):

        # delete 'user' from kwargs before calling perent init

        user = kwargs.pop('user', None)
        super().__init__(*args, **kwargs)
        #количество строк в поле комментариев
        self.fields['comment'].widget = Textarea(attrs={'rows': 3})

так работает, но если я добавляю вот это для редактирования отображения полей в форме

        self.fields['comment'].widget = Textarea(attrs={'rows': 3})

тогда у меня вот такая ошибка

TypeError at /new-big-print-order

__init__() got an unexpected keyword argument 'user'

Я так понимаю потому что во views.py вот это

def get_form_kwargs(self):
    kwargs = super(OrderNewBigPrintView, self).get_form_kwargs()
    kwargs['user'] = self.request.user
    return kwargs

Уже приводил вариант без self, хотя и с self должно бы работать нормально, но раз ругается попробуйте без self.

        # user without self

А как тогда?

self.fields['name_job'].queryset = TypJob.objects.filter(author__id=self.user.id)

как тогда фильтр будет работать?

Не нужно нигде  в классе формы обращаться к  'self.user'.  

среда, 29 апреля 2020 г., 19:49:45 UTC+3 пользователь Sergei Sokov написал:

без self такая ошибка

'OrderForm' object has no attribute 'user'

Если 'user'  в классе не нужен, можно не вешать его на self. просто вместо 'self.user' используем 'user': в этом случае 'user' просто локальная переменная метода init.

Работает!

Но!

Теперь у меня не получается управлять внешним видом полей

Я хочу переопределить класс в форме, но "user" из представления попадает в этот __init__  тоже
