在Django FormWizard中获取以前输入的信息

Question

我正在尝试使用FormWizard创建一个简单的Django多页面表单.表格应该做的是以下内容:

1. 让访问者在表单中输入名字和姓氏.
2. 继续到下一页输入之前输入的firstname和lastname,此页面上还会有一个字段让访问者输入消息.
3. 屏幕将被带到Django done.html页面,其中将存储和显示所有信息.

在第2步中,我无法确定如何显示访问者在步骤1中输入的信息.我正在发布表单的代码以及用于下面步骤1和2的两个模板:

forms.py

from django import forms
from django.shortcuts import render_to_response
from django.contrib.formtools.wizard import FormWizard

class ContactWizard(FormWizard):
    def done(self, request, form_list):
        return render_to_response('done.html', {
            'form_data': [form.cleaned_data for form in form_list],
        })

    def get_template(self, step):
        return 'buydomain/templates/reg%s.html' % step

class Form1(forms.Form):
    firstName = forms.CharField()
    lastName = forms.CharField()

class Form2(forms.Form):
    message = forms.CharField(widget=forms.Textarea)

第1步的模板:

{% block content %}
<p>Step {{ step }} of {{ step_count }}</p>
<form action="." method="post">
<table>
{{ form }}
</table>
<input type="hidden" name="{{ step_field }}" value="{{ step0 }}" />
{{ previous_fields|safe }}
<input type="submit">
</form>
{% endblock %}

第2步的模板:

{% block content %}
<p>Step {{ step }} of {{ step_count }}</p>


{% comment %}
Show values entered into Form1 here !
{% endcomment %}

<form action="." method="post">
<table>
{{ form }}
</table>
<input type="hidden" name="{{ step_field }}" value="{{ step0 }}" />
{{ previous_fields|safe }}
<input type="submit">
</form>
{% endblock %}

如果我有点不清楚我想要实现什么,我很抱歉,我希望等待有人提供解决方案.提前致谢.

Answer 1

首先是一些一般性建议 - 如果你不理解如何在Django中使用某些东西,请拉出该文本编辑器并查看代码.它并不总是获得答案的最快方式,但我认为从长远来看它会带来好处.

尝试通过覆盖FormWizard子类中的process_step来向第二步添加一些extra_context.以下是FormWizard(django 1.1)中的注释:

 def process_step(self, request, form, step):
        """
        Hook for modifying the FormWizard's internal state, given a fully
        validated Form object. The Form is guaranteed to have clean, valid
        data.

        This method should *not* modify any of that data. Rather, it might want
        to set self.extra_context or dynamically alter self.form_list, based on
        previously submitted forms.

        Note that this method is called every time a page is rendered for *all*
        submitted steps.
        """
        pass

所以在你自己的ContactWizard类中,类似的东西(注意:我没有运行它):

class ContactWizard(FormWizard):
    def process_step(self,request,form,step):
        if step == 1:
            self.extra_context = {'whatever': form.whatever_you_want_from_the_form}
            return
        else:
            return
