Question

这里的目标是：当用户提交表单时，使用一个视图将提交的数据发送到数据库，然后重定向回到表单，但预先填充了数据。这主要是工作，但关于我的实现的一些事情是在字符串周围包含额外的引号。现在，我只是使用超简单的形式，顺便说一句。我输入Billy，然后预先弹出："Billy"，如果我再次点击提交，它会返回："\"Billy\""，然后是"\"\\\"Billy\\\"\""，依此类推（如就我所测试而言，无论如何。

相关观点是：

def editUsers(request):
    if request.method == 'POST':
        # create a form instance and populate it with data from the request:
        form = usersForm(request.POST)
        # check whether it's valid:
        # process the data in form.cleaned_data as required
        # redirect to a new URL:
        name = json.dumps(form.data['user_name'])
        request.session['editUserName'] = name

        # call out to limboLogic.py to update values

        test = name
        return redirect('../users')
    # if a GET (or any other method) we'll create a blank form
    else:
        return redirect('../users')

from .forms import *

def users(request):
    form = None

    if 'editUserName' not in request.session:
        # create a blank form
        form = usersForm()
    else:
        # form = equipmentForm(initial='jim') - used to make sure I was branching the if/else correctly
        form = usersForm(initial={'user_name':request.session['editUserName']}, auto_id=False) #limboLogic.GetUserInfo(name))
    return render(request, 'limboHtml/UserManagement.html', {'form': form})

形式简单：

class usersForm(forms.Form):
    user_name = forms.CharField(label='New User\'s  name', max_length=100)

，模板是：

{% extends "base.html" %}

{% block content %}
 <div class="row">
    <p>This is the user management page</p><br>
    <form action="/edit/users.html" method="post">
        {% csrf_token %}
        {{ form }}
        <input type="submit" value="OK">
    </form>
    <br><p class="bold">This is below the form</p>
  </div>
{% endblock %}

想法？

我不能完全说出这里的内部情况，但问题涉及到我使用的是json类。我使用this site作为指南并设法解决问题。请注意，关键方面是在第二个if：

内

name = form.cleaned_data['user_name']工作正常，

name = json.dumps(form.data['user_name'])不

现在的整个功能：

def editUsers(request):
    if request.method == 'POST':
        # create a form instance and populate it with data from the request:
        form = usersForm(request.POST)
        # check whether it's valid:
        # process the data in form.cleaned_data as required
        # redirect to a new URL:
        if form.is_valid():
            name = form.cleaned_data['user_name']
            # name = json.dumps(form.data['user_name'])
            request.session['editUserName'] = name

            # call out to limboLogic.py to update values

            test = name
            return redirect('../users')
    # if a GET (or any other method) we'll create a blank form
    return redirect('../users')

django在随后的提交中添加引号
