上面的views.py和index.html用于保存新用户条目.
我的html模板分为2部分,主帐户持有人选项卡和授权记者选项卡.主帐户持有人选项卡用于保存个人资料信息,授权记者选项卡用于创建新用户.页面加载主帐户持有人选项卡将处于活动状态且用户选项卡将被隐藏.如果选择了用户选项卡,将隐藏主帐户持有人选项卡.一旦用户被保存,用户详细信息将以下面的格式显示.
{% for list in member_list %}
<tr class="ir-shade">
<td style="width:120px;"><span><input type="submit" name="delete" value="{{list.0.id}}" class="delete_reporter" /></span><button> id="{{ list.0.id }}" class="openDiv">{{list.0.first_name|title}} {{list.0.last_name}}</button></td>
<td style="width:410px;"> {{list.0.email}} {{list.1.phone_daytime}} {{list.1.phone_mobile}}</td>
</tr>
{% endfor %}
我真正想要的是点击< button> id =“{{list.0.id}}”class =“openDiv”> {{list.0.first_name | title}} {{list.0.last_name}}< / button>保存的用户数据应显示在可编辑模式的相同字段中.我在按钮中传递用户ID.单击按钮,与用户ID相关的数据应以可编辑模式显示.
JS：
$('.openDiv').click(function () {
var id = $(this).attr('id');
var csrf_token = $("#csrf_token").val();
$.ajax({
data:{
csrfmiddlewaretoken: ('{{csrf_token}}'),
id:id,
},
type:'POST',
url: '/setting/save-reporter/',
success: function(data) {
$('#authorisedreporter').html(data);
}
});
});
下面的views.py和html是为了显示已保存的表单实例而编写的.现在我可以显示已保存的表单实例,并且我将实例加载到authorisedreporter div中(请检入js和index.html).这次,如果我是工具包保存,它正在创建新记录,它正在调用与index方法相关的views.py.I想要更新而不保存记录.
save_reporter.html
<form method="post" action="." id="{{ id }}">
{% csrf_token %}
<table width="100%">
<tr>
<td style="width:100px;">First name:</td><td>{{form.first_name}}</td>
</tr>
<tr>
<td>Last name:</td><td>{{form.last_name}}</td>
</tr>
<tr>
<td>Daytime phone:</td><td>{{profile.phone_daytime}}</td>
</tr>
<tr>
<td>Mobile phone:</td><td>{{profile.phone_mobile}}</td>
</tr>
<tr>
<td>Email:</td><td>{{form.email}}</td>
</tr>
<tr>
<td>Password</td><td>{{form.password}}</td>
</tr>
<tr>
<td colspan=2"<p align="right">{% include "buttons/save.html" %}</p></td>
</tr></table></form>
views.py
def save_reporter(request):
user = request.user
id = request.POST.get('id')
user = User.objects.get(pk =id)
userprofile = UserProfile.objects.get(user=user.id)
form = ReporterRegisterForm(instance=user)
profileform = ProfilecontactForm(instance=userprofile)
return render(request, 'setting/save_reporter.html',
{'form': form,
'id':id,
'profile':profileform
})
我已经解释了我当前面临的问题,请帮我做这件事.谢谢
解决方法:
让我分析一下你的JS代码,因为我可以看到几个错误/错误：
$('.openDiv').click(function (e) {
e.preventDefault();
// where is following data taken from? At the point you click the .openDiv link, the form doesn't have any data yet so all of them will be empty string ''
var csrf_token = $("#csrf_token").val();
var id = $(this).closest('td').attr('id');
var firstname = $("#"+id).find('#id_first_name').val();
var lastname = $("#"+id).find('#id_last_name').val();
var phonedaytime = $("#"+id).find('#id_phone_daytime').val();
var phonemobile = $("#"+id).find('#id_phone_mobile').val();
var email = $("#"+id).find('#id_email').val();
// do you use AJAX to get the form or use it to save the form?
$.ajax({
data: $(this).serialize(), // this is wrong, $(this) is the link object, not a form
type:'POST',
url: '/setting/save-reporter/',
success: function(data) {
$('#authorisedreporter').html(data);
$('#authorisedreporter').show();
}
});
});
好的据我所知,在点击链接后,您正在使用AJAX向Django视图发送请求以获取正确的实例化表单.所以你应该：
首先,简化您的JS代码：
$('.openDiv').click(function (e) {
e.preventDefault();
var this_id = $(this).closest('td').attr('id'); // get the user ID, since that's all you need
console.log(this_id); // making sure that you get the right ID
$.ajax({
data: { id: this_id },
type: 'POST',
url: '/setting/fetch-reporter-form/',
success: function(data) {
$('#authorisedreporter').html(data);
$('#authorisedreporter').show();
}
});
});
接下来,将旧视图拆分为多个视图以关注它需要做什么(注意：您可以保留索引视图)：
def fetch_reporter_form(request):
''' Change your save_reporter view name to this view '''
registerform = UserRegisterForm()
if request.method == 'POST':
id = request.POST.get('id', None)
if id:
user = get_object_or_404(pk=user.id)
userprofile = UserProfile.objects.get(user=user)
registerform = UserRegisterForm(request.POST, instance=user)
return render(request, 'setting/register_form.html', {
'user_id': id
'registerform':registerform
})
else:
return HttpResponse('Request does not contain any ID')
else:
return HttpResponse('Request is not POST')
def update_reporter(request):
''' This function is for update the reporter '''
registerform = UserRegisterForm()
if request.method == 'POST':
id = request.POST.get('id', None)
if id:
user = get_object_or_404(pk=user.id)
userprofile = UserProfile.objects.get(user=user)
registerform = UserRegisterForm(request.POST, instance=user)
if registerform.is_valid():
result = registerform.save(commit=False)
# saving code here ...
return HttpResponse('Success')
else:
return HttpResponse('Request does not contain any ID')
else:
return HttpResponse('Request is not POST')
你可以看到这里有两个函数：1用于从AJAX中获取正确的表单,另一个用于通过普通表单提交保存数据.当然你应该相应地制作urls.py,例如：
urlpatterns = patterns('',
# ... your code ...
url(r'^setting/fetch-reporter-form/$', 'yourapp.views.fetch_reporter_form'),
url(r'^setting/update-reporter/$', 'yourapp.views.update_reporter'),
)
您可能还会注意到,您应该创建一个新模板设置/ register_form.html,其中仅包含您的注册表单HTML(注意：您需要一个隐藏的id字段,该字段由上面的fetch_reporter_form视图返回以标识表单)：
<form method="post" action="/setting/update-reporter" id="reporter-form">
{% csrf_token %}
<input type="hidden" name="id" value="{{ user_id }}" />
<!-- your code here -->
</form>
所以流程是：
>您转到索引视图.正常情况下有几种形式可以保存新记者等.
>您单击.openDiv按钮.它会将上面的AJAX请求发送到fetch_reporter_form以获取正确的表单. (此时您的代码工作正常)
>单击该表单上的“保存”按钮,它将更新数据(通过POST)提交到update_report视图并更新报告者.
我只想给你一个基本的想法.剩下的很简单,所以我猜你可以轻松继续.希望能帮助到你！
