Question

我正在与Django建立EC市场。我们创建了商店列表页面和商店详情页面。此外，我希望能够在商店的详细信息页面上向每个商店发送邮件。

但是，我们不知道如何在商店详情页面上发送邮件时将send_mail的recipient_list更改为每个商店的mailAddress。

■view.py

import collections

with open("common.txt", "r") as f:  # open the `common.txt` for reading
    common_words = {l.strip().lower() for l in f}  # read each line and and add it to a set

interpunction = ";,'\"."  # define word separating characters and create a translation table
trans_table = str.maketrans(interpunction, " " * len(interpunction))

sentences_counter = []  # a list to hold a word count for each sentence

word_counter = collections.defaultdict(int)  # a string:int default dict for counting
with open("sample.txt", "r") as f:  # open the `sample.txt` for reading
    for line in f:  # read the file line by line
        for word in line.translate(trans_table).split():  # remove interpunction and split
            if word.lower() not in common_words:  # count only words not in the common.txt
                word_counter[word.lower()] += 1  # increase the count

print("\n".join("{}: {}".format(w, c) for w, c in word_counter.items()))  # print the counts

■model.py

from django.views import generic
from django.views.generic.edit import ShopView
from django.views.generic.edit import FormMixin
from .models import Shop
from .forms import ContactForm

class ShopView(FormMixin, generic.DetailView):

    model = Shop
    form_class = ContactForm

    def get_template_names(self):
        return 'shopSearch/shop_detail.html'

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        return context

    def get_success_url(self):
        return 'contact/finish/'

    def post(self, request, *args, **kwargs):
        self.object = self.get_object()
        form = self.get_form()

        if form.is_valid():
            return self.form_valid(form)
        else:
            return self.form_invalid(form)

    def form_valid(self, form):
        form.send_email()
        return super().form_valid(form)

■form.py

class Shop(models.Model):
    name         = models.CharField(max_length=255)
    mailAddress  = models.CharField(max_length=100, null=True, blank=True)

您可以将send_email与to一起使用。

class ContactForm(forms.Form):
    title = forms.CharField()
    email = forms.EmailField()
    contents = forms.CharField(widget=forms.Textarea)

    def send_email(self, to):
        subject = self.cleaned_data['title']
        from_email = self.cleaned_data['email']
        contents = self.cleaned_data['contents']
        message = '\n\ncontens:\n' + contents + '\n\nfrom to:\n' + from_email
        send_mail(subject, message, settings.EMAIL_HOST_USER, to)

并在to中传递form_valid()列表。

...
def form_valid(self, form):
    # set to email list for your model
    # maybe you want to this?
    to = [self.object.mailAddress]
    form.send_email(to)
    return super().form_valid(form)

如何制作send_mail变量的recipient_list？
