问题描述
TONAL_TYPES = ['positive','negative','neutral','undefined']
为此,我正在为一组“专家”构建一项服务,该服务将考虑每条评论 3 次,并根据“多数规则”做出决定。
我有以下型号:
class Result(models.Model):
text = models.TextField(null=True)
title = models.TextField(null=True)
class Comment(models.Model):
text = models.TextField(blank=True,null=True)
result = models.ForeignKey(Result,models.DO_nothing,null=True)
class CommentRound(models.Model):
comment = models.ForeignKey(Comment,blank=True,null=True)
tonal_type = models.CharField(choices=TONAL_TYPES,default='1')
目前前两件事正在使用以下代码(简化):
[views.py]
from django.forms import inlineformset_factory
from ..forms import ResultForm,CommentForm
from ..models import Result,Comment
def createResult(request):
CommentFormSet = inlineformset_factory(Result,Comment,form=CommentForm,can_delete=False,extra=3,max_num=1)
if request.method == 'POST':
form = ResultForm(request.POST)
if form.is_valid():
result = form.save()
formset = CommentFormSet(request.POST,instance=result)
if formset.is_valid():
formset.save()
return redirect('/')
else:
logger.debug(formset.errors)
else:
logger.debug(form.errors)
else:
form = ResultForm()
formset = CommentFormSet()
render(request,'my_app/result_form.html',{'form': form,'formset': formset})
[forms.py]
from django.forms import ModelForm
from django import forms
class CommentForm(ModelForm):
class Meta:
model = Comment
class ResultForm(ModelForm):
class Meta:
model = Result
如何向表单集中的每条评论添加一个或多个“CommentRound”实例? (在这个例子中,'CommentRound' 被大大简化了;实际上,其中有相当多的评估参数。)
