Question

Hi Stack溢出的人：

我愿意接受以下新手python错误

中的一些方向

我在forms.py中有两个模型表单：

class StrategicDnaValuePropositionForm(forms.ModelForm):
    title = "Adn Estratégico y Propuesta de valor"

    class Meta:
        widgets = {
            'familiar_enterprise':forms.RadioSelect,
            'enterprise_concepts':forms.RadioSelect,
            'value_purpose_target':forms.RadioSelect,
            'competition_differentiation':forms.RadioSelect,
            'goals_objectives':forms.RadioSelect,
            'avoid_competition':forms.RadioSelect,
            'enterprise_strategy':forms.RadioSelect,
        }

        model = StrategicDnaValueProposition
        fields = ('familiar_enterprise', 'enterprise_size',
            'enterprise_concepts', 'value_purpose_target', 'competition_differentiation', 'goals_objectives',
            'avoid_competition')


class MarketingSalesForm(forms.ModelForm):
    title = "Mercadeo y Ventas"

    class Meta:
        widgets = {
            'key_activities':forms.RadioSelect,
            'new_clients_strategies':forms.RadioSelect,
        }

        model = MarketingSales
        fields = ('key_activities', 'new_clients_strategies',)

在我看来，我想生成这些模型表单的两个表单实例并发送到模板以保存它们。

我的views.py:

@login_required
def diagnostic_tool_questions(request):
    user = request.user

    # Populate the forms
    form_diagnostic = []

    if user.is_enterprise:
        profile = user.get_enterprise_profile()
        form_diagnostic.append({
            'form_strategicdna': StrategicDnaValuePropositionForm,
            'form_marketing_sales': MarketingSalesForm,
            'instance': user.enterpriseprofile,
        })

    if request.method == 'POST':
        # forms = [x['form'](data=request.POST,) for x in form_diagnostic]
        forms = [x['form'](data=request.POST, instance=x['instance'],) for x in form_diagnostic]
        if all([form.is_valid() for form in forms]):
            for form in forms:
                form.save()
            return redirect('dashboard')
    else:
        forms = [x['form'](instance=x['instance']) for x in form_diagnostic]
    return render(
        request, 'enterprise_process/strategicdnavalueproposition_form.html',
        {'forms':forms, 'userprofile':profile,})

我的模板是：

{% extends 'layout.html' %}
{% load bootstrap3 %}

{% block title_tag %}Herramienta de Diagnóstico | CRIMBLU {{ block.super }}{% endblock %}

{% block body_content %}
<div class="container">
    <h1>Account Details</h1>
    <form method="POST">
        {% csrf_token %}
        {% for form in forms %}
            {% bootstrap_form form %}
        {% endfor %}
        <input type="submit" value="Save Changes" class="btn btn-default">
    </form>
</div>

{% endblock %}

当我转到调用我的diagnostic_tool_questions视图的url时，我收到以下消息：

Django告诉我，我在行中有一些解释错误：

else:
        forms = [x['form'](instance=x['instance']) for x in form_diagnostic]

KeyError: 'form'我不知道出现的原因...... 请原谅我的新手错误。

将多个实例表单发送到模板 - Django
