添加自定义布局时，Django Crispy 表单不会保存

Question

来自 views.py:

class EmployeeUpdateView(LoginRequiredMixin, UpdateView):
    model = Employee
    template_name = "employee_update.html"
    form_class = EmployeeUpdateForm

来自forms.py：

class EmployeeForm(forms.ModelForm):
    departments = DepartmentChoiceField()

    def __init__(self, *args, **kwargs):
        super(EmployeeForm, self).__init__(*args, **kwargs)

        self.helper = FormHelper()
        self.helper.form_class = "form-vertical"
        self.helper.form_tag = False
        self.helper.layout = Layout(
            Div(Field('first_name'), css_class="row col-md-5 emp-firstname"),
            Div(Field('last_name'), css_class="row col-md-5"),
            Div(Field('title'), css_class="row col-md-10"),
            Div(Field('email'), css_class="row col-md-10"),
            Div(Field('phone_number'), css_class="row col-md-10"),
            Div(Field('slack_username'), css_class="row col-md-10"),
            Div(Field('department'), css_class="row col-md-5"),
            Div(
                Div(Field('facility_agent', template="field_checkbox_awesome.html"), css_class="row checkbox checkbox-doorman"),
                Div(Field('company_agent', template="field_checkbox_awesome.html"), css_class="row checkbox checkbox-doorman"),
                Div(Field('contact_for_company_delivery', template="field_checkbox_awesome.html"), css_class="row checkbox checkbox-doorman"),
                Div(Field('contact_for_facility_delivery', template="field_checkbox_awesome.html"), css_class="row checkbox checkbox-doorman"),
                css_class="row col-md-5 emp-department"),
            Div(Field('mugshot'), css_class="row col-md-10"),
            Div(Field('company'), css_class="row col-md-10"),
            Div(Field('facility'), css_class="row col-md-10")
        )
        self.request = kwargs.pop('request', None)
        self.fields['first_name'].label = "first name"
        self.fields['last_name'].label = "last name"
        self.fields['title'].label = "title"
        self.fields['email'].label = "email"
        self.fields['phone_number'].label = "phone #"
        self.fields['slack_username'].label = "slack name"
        self.fields['facility_agent'].label = "facility agent"
        self.fields['company_agent'].label = "company agent"
        self.fields['contact_for_company_delivery'].label = "contact for company delivery"
        self.fields['contact_for_facility_delivery'].label = "contact for facility delivery"

    class Meta:
        model = Employee


class EmployeeCreateForm(EmployeeForm):
    def __init__(self, *args, **kwargs):
        super(EmployeeCreateForm, self).__init__(*args, **kwargs)


class EmployeeUpdateForm(EmployeeForm):
    def __init__(self, *args, **kwargs):
        super(EmployeeUpdateForm, self).__init__(*args, **kwargs)

        employee = Employee.objects.filter(pk=self.instance.pk).first()
        self.fields['departments'].set_company(employee.department_id)

和urls.py：

url(r'employees/(?P<pk>[0-9]+)/$', EmployeeUpdateView.as_view(), name="employee_update"),

如果我注释掉 views.py 中的 "form_class = " 行，编辑将被保存。如果我把它放进去，编辑就不会了。这些字段肯定是通过 POST 发送的，并且控制台上没有记录任何错误。

Answer 1

因为 form_valid 没有被调用，这意味着问题不是您的表单没有保存，而是您传递给表单的数据没有通过验证。 Take a look here at the docs.

要调试问题，首先在您的视图中放置一个 form_invalid() 方法或在您的表单中放置一个 custom clean() method ，然后查看表单未通过验证的原因。即，检查表单实例中的错误并查看向您显示的内容。那应该回答你的问题。

还有一些您正在调用的方法可能会或可能不会使表单在实例化之前就无效。我不确定 set_company 方法在某个字段上做了什么，但它可能会出错，导致您的表单设置不正确。
