请帮助我使用表单
访问模板中的m2m值我的模特:
class Opportunity(models.Model):
sfdc_id = models.PositiveIntegerField(null=True, blank=True)
class Event(models.Model):
background = models.TextField(null=True, blank=True)
account = models.ForeignKey(Account)
opportunities = models.ManyToManyField(Opportunity, null=True, blank=True)
Views.py
def event(request,event_id):
if request.method == 'GET' :
eventForm=EventForm(instance=Event.objects.get(pk=event_id))
locationForm = LocationForm(prefix='location')
return render(request,'events/event.html', {'eventForm': eventForm, 'locationForm': locationForm})
更新了模型表格:
class EventForm(ModelForm):
account = ModelChoiceField(queryset=Account.objects.all())
background = CharField(widget=Textarea(attrs={'class':'form-textarea resizeoff auto-resize js_auto_resize default'}), required=False)
opportunities = CharField(label='SalesForce ID', widget=TextInput(attrs={'class' : 'form-input'}), required=False)
在我的模板中,我尝试过以下代码,但不能正常工作
{% for attr in eventForm.opportunities.all %}
<td>{{ attr.sfdc_id }}</td>
{% endfor %}
我试过这个但仍然无法正常工作
{% for attr in eventForm.opportunities_set.all %}
<td>{{ attr.sfdc_id }}</td>
{% endfor %}

在您的表单中,将商机的定义更改为:
class EventForm(ModelForm):
account = ModelChoiceField(queryset=Account.objects.all())
background = CharField(widget=Textarea(attrs={'class':'form-textarea resizeoff auto-resize js_auto_resize default'}), required=False)
opportunities = ModelMultipleChoiceField(queryset=Opportinuty.objects.all(), label='SalesForce ID', required=False)

这将呈现适当的M2M表单控件。 如果您希望将小部件更改为更有用的小部件,我建议您查看django-selectable
它有一个很好的AutocomboboxSelectMultipleWidget我觉得非常有用(而且很棒!)
