将多个收件人电子邮件和名称添加到EmailMultiAlternatives中 [英] Append multiple recipient email and name into EmailMultiAlternatives

问题描述

我有一个表单mixin，用户输入一个消息并将其发送给多个收件人。我正在使用Mandrill作为我的电子邮件客户端。我目前可以将电子邮件发送给单个收件人，但是在输入多个用户时失败。

这是形式mixin

 类FormListView（FormMixin，ListView ）
 def get（self，request，* args，** kwargs）：
 form_class = self.get_form_class（）
 self.form = self.get_form（form_class）
 self.object_list = self.get_queryset（）
 context = self.get_context_data（object_list = self.object_list，form = self.form）
返回self.render_to_response（上下文）
 
类CardListNew（FormListView）：
 form_class = EmailForm 
 model = card 
 
 def get_queryset（self）：
 
 return card.objects.filter（pk__in = [1]）。filter（is_published ='true'）
 
 def sendmail（request）：
如果request.method =='POST'：
 form = EmailForm request.POST）
如果form.is_valid（）：
 fullname = form.cleaned_data ['name'] 
 email = form.cleaned_data ['email'] 
 rname = form .cleaned_data ['rname'] 
 rema il = form.cleaned_data ['remail'] 
 subject =你收到一封电子邮件+ fullname 
 message = form.cleaned_data ['message'] 
 connection = get_connection（）
 connection.open（）
 text_content = message 
 
 msg = EmailMultiAlternatives（subject，message，email，[remail]）
 template_data = {
'sender_name' ：fullname，'sender_email'：email，'receiver_name'：rname，'receiver_email'：remail，'message'：message 
} 
 html_content = render_to_string（email.html，template_data）
 msg.attach_alternative（html_content，text / html）
 msg.send（）
 connection.close（）＃清理
返回HttpResponseRedirect（'/ thank-you /'）
 else：
 form = EmailForm（）
 
 return render（request，'card.html'）
  

这是提交电子邮件的表单。我目前使用相同的输入名称来接收电子邮件和接收者名称。

 < form role =formaction =/ sendmail /method =post> 
 
< input type =textname =nameclass =form-control inputid =input1autocomplete =offplaceholder =Enter Name> 
 
< input type =textname =emailclass =form-control inputid =input2autocomplete =offplaceholder =Enter Email> 
 
< input class ='form-control reciptest'name =rnameplaceholder ='收件人名称'type ='text'> 
 
< input type =textclass =form-control emailtestname =remailplaceholder =收件人电子邮件> 
 
< a class =btn btn-sm btn-defaultonClick =addInput（'dynamicInput'）;>添加收件人< / a> 
< a class =btn btn-sm btn-defaultonClick =removeInput（'dynamicInput'）;>删除收件人< / a> 
 
< textarea id =input3name =messageclass =form-control inputrows =6placeholder =不超过1000个字母maxlength =1000> < / textarea的> 
  

如何拆分和匹配列表收件人姓名和电子邮件，并将其附加到EmailMultiAlternatives ）和template_data？

解决方案

EmailMultiAlternatives获取to参数的电子邮件地址列表，所以一个简单的方法可能是更改：

  msg = EmailMultiAlternatives（主题，消息，电子邮件，[remail]）
  

to：

  msg = EmailMultiAlternatives ，消息，电子邮件，remail.split（'，'））
  

将remail字段放入列表中，每个逗号。

Hi I have a form mixin which the user inputs a message and sends it to multiple recipients. I am using Mandrill as my email client. I am currently able to send the email to a single recipient, but it fails when inputting more then one user.

This is the form mixin

class FormListView(FormMixin, ListView):
    def get(self, request, *args, **kwargs):
    form_class = self.get_form_class()
    self.form = self.get_form(form_class)
    self.object_list = self.get_queryset()
    context = self.get_context_data(object_list=self.object_list, form=self.form)
    return self.render_to_response(context)

class CardListNew(FormListView):
    form_class = EmailForm
    model = card

    def get_queryset(self):

    return card.objects.filter(pk__in=[1]).filter(is_published='true')

def sendmail(request):
    if request.method == 'POST':
        form = EmailForm(request.POST)
        if form.is_valid():
           fullname = form.cleaned_data['name']
           email = form.cleaned_data['email']
           rname = form.cleaned_data['rname']
           remail = form.cleaned_data['remail']
           subject = "You received an email from " +  fullname
           message = form.cleaned_data['message']
           connection = get_connection()
           connection.open()
           text_content =  message

           msg = EmailMultiAlternatives(subject, message, email, [remail])
           template_data = {
                         'sender_name': fullname, 'sender_email': email, 'receiver_name': rname, 'receiver_email': remail, 'message': message
        }
           html_content = render_to_string("email.html", template_data)
           msg.attach_alternative( html_content , "text/html")
           msg.send()
           connection.close() # Cleanup
           return HttpResponseRedirect('/thank-you/')
   else:
       form = EmailForm()

   return render(request, 'card.html')  

This is the form that submits the email. I currently use the same input name for the receiver email and receiver name.

<form role="form" action="/sendmail/" method="post">

<input type="text" name="name" class="form-control input" id="input1" autocomplete="off" placeholder="Enter Name">

<input type="text" name="email" class="form-control input" id="input2" autocomplete="off" placeholder="Enter Email">

<input class='form-control reciptest' name="rname" placeholder='Recipient Name' type='text'>

<input type="text" class="form-control emailtest" name="remail" placeholder="Recipient Email">

<a  class="btn btn-sm btn-default" onClick="addInput('dynamicInput');">Add Recipient </a>
<a class="btn btn-sm btn-default" onClick="removeInput('dynamicInput');">Remove Recipient</a>

<textarea id="input3" name="message" class="form-control input" rows="6" placeholder="Not more than 1000 letters" maxlength="1000"></textarea>

How would I go about in splitting and matching the lists recipients name and email and append it into EmailMultiAlternatives() and template_data?

解决方案

EmailMultiAlternatives takes a list of email addresses for the "to" parameter, so a simple approach could be to change:

   msg = EmailMultiAlternatives(subject, message, email, [remail])

to:

   msg = EmailMultiAlternatives(subject, message, email, remail.split(','))

which will break apart the text of the remail field into a list, at each comma.
