我正在使用一种非常简单的表单将数据发布到Django(2)中,但是由于form.is_valid()
未被调用,因此总是使该表单无效。
这是我到目前为止所拥有的:
来自models.py
:
class UserGroup(models.Model):
email = models.EmailField(primary_key=True)
group = models.CharField(max_length=250, default='notingroup')
def __str__(self):
return self.group
来自forms.py
:
class UserGroupForm(forms.ModelForm):
class Meta:
model = UserGroup
fields = ('group', 'email')
来自views.py
:
def group_name(request):
error = ''
if request.method == 'POST':
print(request.POST['email'])
group_form = UserGroupForm(request.POST)
print(group_form)
if group_form.is_valid():
ug_obj = UserGroup()
ug_obj.group = group_form.cleaned_data['group']
ug_obj.email = group_form.cleaned_data['email']
ug_obj.save()
return JsonResponse({"message": 'Got it inside valid'})
else:
error = 'Something went wrong'
print(error)
return JsonResponse({"message": 'an error occurs!'})
来自html template
:
<form method="post" id="gitForm" action="javascript:call_my_form()">
{% csrf_token %}
<label>Groupname: </label>
<input id="user_email" type="text" value="{{ user.email }}" hidden>
<input id="input" type="text" class="">
<input type="submit" value="Mehet" class="btn btn-primary">
<div id="error" style="color:red"></div>
</form>
来自javasctip function for Ajax
:
function call_my_form() {
$(document).on('submit', '#gitForm', function (e) {
e.preventDefault();
console.log($('#input').val());
console.log($('#user_email').val());
$.ajax({
type: 'POST',
url: '/groupname',
data: {
group: $('#input').val(),
email: $('#user_email').val(),
csrfmiddlewaretoken: $('input[name=csrfmiddlewaretoken]').val()
},
success: function (jsonResponse) {
document.getElementById("demo").innerHTML = jsonResponse.message;
}
}).done(function (jsonResponse) {
document.getElementById("demo").innerHTML = jsonResponse.message;
})
});
}
我在视图中获取了正确的数据,但仍未调用form.is_valid()
以下是输出:
********** @ mail.com
<tr><th><label for="id_group">Group:</label></th><td><input type="text" name="group" value="scsacas" maxlength="250" required id="id_group"></td></tr> <tr><th><label for="id_email">Email:</label></th><td><ul class="errorlist"><li>User group with this Email already exists.</li></ul><input type="email" name="email" value="abdul12391@gmail.com" maxlength="254" required id="id_email"></td></tr>

答案 0 :(得分:1)
如您的输出中所述:User group with this Email already exists.
因此,您正在尝试提交已存在的电子邮件。这就是为什么您的form.is_valid()
不被呼叫的原因。
