这个话题已经讨论过好几次了,但我似乎无法让它发挥作用:
如何在 twitter-bootstrap 模式窗口中插入 django 表单?
Twitter-Bootstrap 模式中的简单 Django 表单
http://www.micahcarrick.com/ajax-form-submission-django.html
我有一个项目表,每一行都附有一个编辑按钮。单击时,将显示 UpdateView 的模式表单。我能够检索正确的记录,但在提交时,我无法获得 aysnc 提交,因此页面不会重定向。
我的表格:
class RSVPForm(forms.ModelForm):
class Meta:
model=RSVP
fields = ['status', 'notes', 'comments']
视图 - UpdateView 继承了 django 文档中的 AjaxableResponseMixin:
import json
from django.http import HttpResponse
from braces.views import LoginRequiredMixin
from django.views.generic import UpdateView
class AjaxableResponseMixin(object):
def render_to_json_response(self, context, **response_kwargs):
data = json.dumps(context)
response_kwargs['content_type'] = 'application/json'
return HttpResponse(data, **response_kwargs)
def form_invalid(self, form):
response = super(AjaxableResponseMixin, self).form_invalid(form)
if self.request.is_ajax():
return self.render_to_json_response(form.errors, status=400)
else:
return response
def form_valid(self, form):
response = super(AjaxableResponseMixin, self).form_valid(form)
if self.request.is_ajax():
data = {
'pk': self.object.pk,
}
return self.render_to_json_response(data)
else:
return response
class RSVPUpdateView(LoginRequiredMixin, AjaxableResponseMixin, UpdateView):
model = RSVP
form_class = RSVPForm
template_name = 'rsvp/rsvp_modal.html'
success_url = reverse_lazy('rsvp:rsvp_list')
JS:
$(document).ready(function(){
$('.rsvp-form').submit(function() {
$.ajax({
type: $(this).attr('method'),
url: $(this).attr('action'),
data: $(this).serialize(),
success: function() { // on success..
$('#success_div').append('Changes saved'); // update the DIV
$('#success_div').toggleClass('alert alert-success'); // unhide
},
error: function(xhr, ajaxOptions, thrownError) { // on error..
$('#error_div').append(xhr); // update the DIV
$('#error_div').toggleClass('alert alert-error'); // unhide
}
});
return false;
});
});
我不确定为什么return false;
在 js 中没有抑制表单提交。我尝试使用e.preventDefault();
但没有结果。我认为这是某个地方的疏忽,如果有人能发现它,我将不胜感激。也许是对 AjaxableResponseMixin 的更改?
编辑:添加模板
在模态表单的模板中:
{% load crispy_forms_tags %}
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<div id="success_div" class="alert alert-success hide"><button type="button" class="close" data-dismiss="alert">×</button></div>
<div id="error_div" class="alert alert-error hide"><button type="button" class="close" data-dismiss="alert">×</button></div>
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h4 class="modal-title">RSVP Details</h4>
</div>
<!-- form here -->
<form class="rsvp-form" method="post" action="{% url 'rsvp:rsvp_update' pk=form.instance.id %}">
<div class="modal-body">
{% crispy form form.helper %}
</div>
<div class="modal-footer">
<input class="btn btn-primary" id="modal-submit" type="submit" value="Save" />
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</form>
</div>
</div>
该表单使用以下js显示:
$(document).ready(function(){
$('.edit-modal').click(function(ev) { // for each update url
ev.preventDefault(); // prevent navigation
var url = $(this).data('form'); // get the update form url
$('#RSVPModal').load(url, function() { // load the url into the modal
$(this).modal('show'); // display the modal on url load
});
return false; // prevent click propagation
});
});
