Django Dajax验证具有多对多字段的模型

我正在使用django和dajax,我正在尝试验证具有多对多字段的项目。我正在使用django表单来创建此模型的表单。当我使用提交按钮提交表单并且在选择框中选择了至少1到x个项目时,模型将得到验证。当我使用dajax时,模型将仅验证我是否选择了至少2个选项框中的项目。

有谁知道为什么会这样?

模型

#Hints
class Hint(models.Model):
title = models.TextField(max_length=200)
body = models.TextField()
industryType = models.ManyToManyField(IndustryType)
screen = models.ManyToManyField(Screen)

#Creates form for a hint
class HintForm(ModelForm):

class Meta:
    model = Hint
    #widgets = {'industryType': CheckboxSelectMultiple, 'screen': CheckboxSelectMultiple }
    industryType = ModelMultipleChoiceField(queryset=IndustryType.objects.all(),
                                                widget=CheckboxSelectMultiple())

模板:

<form id="hintForm"  action="." method="post">

{% csrf_token %}
<table>
{{ form.as_table }}
</table>
<input type="submit" value="Submit"/>
</form>

<input type="button"  onclick="send_form();" value="Add Hint" />

<script>
function send_form(){
    data = $('#hintForm').serializeObject();

    // jQuery
    // If you are using jQuery, you need this form->object serializer
    // https://github.com/cowboy/jquery-misc/blob/master/jquery.ba-serializeobject.js
        alert(data['screen'])
        Dajaxice.THE.send_form(Dajax.process,{'hintform':data});
        return(false)
}

</script>

视图中的代码

def addHint(request):
if request.method == 'POST': # If the form has been submitted...
    form = HintForm(request.POST) # A form bound to the POST data
    if form.is_valid(): # All validation rules pass
        # Process the data in form.cleaned_data
        #savedHint = form.save()
        #messages.success(request, '{0} has been added.'.format(savedHint))
        print "Success"
else:

    form = HintForm() # An unbound form

return render_to_response('manage/screens/form.html', {
    'form': form, 'breadcrumName' : 'Add Screen' }, context_instance=RequestContext(request))

AJAX.py

@dajaxice_register
def send_form(request, hintform):
    dajax = Dajax()
    form = HintForm(hintform)
    print form
    if form.is_valid():

        dajax.alert("This form is_valid")
    else:

        dajax.alert("Not Valid")
    return dajax.json()

答案 0 :(得分:0)

我在使用Dajax序列化表单数据时遇到问题,直到我切换到不同的序列化对象函数。我意识到这不是一个全面且经过测试的答案,但你可以给这个备用序列化功能一个镜头:

也许还会对序列化表单对象执行一些firebug / console输出,以查看它是否/如何被激活。
