为什么这个django表单集突然停止保存内容

Question

我有一个视图，它在同一个模板中呈现了一个表单和一个表单集：

class LearnerUpdateView(LearnerProfileMixin, UpdateView):
model = User
form_class = UserForm
formset_class = LearnerFormSet
template_name = "formset_edit_learner.html"
success_url = reverse_lazy('pages:home')
def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
learner = User.objects.get(learner=self.request.user.learner)
formset = LearnerFormSet(instance=learner)
context["learner_formset"] = formset
return context
def get_object(self, queryset=None):
user = self.request.user
return user
def post(self, request, *args, **kwargs):
self.object = self.get_object()
form_class = self.get_form_class()
form = self.get_form(form_class)
user = User.objects.get(learner=self.get_object().learner)
formsets = LearnerFormSet(self.request.POST, request.FILES, instance=user)
if form.is_valid():
for fs in formsets:
if fs.is_valid():
# Messages test start
messages.success(request, "Profile updated successfully!")
# Messages test end
fs.save()
else:
messages.error(request, "It didn't save!")

return self.form_valid(form)
return self.form_invalid(form)

然后我想让它更漂亮，我添加了select2多复选框小部件和django引导程序日期选择器加

其他地方没有任何变化，但当我提交帖子时，它只保存了与用户相关的数据，而不是与学习者(依赖于表单集(相关的数据

根据消息，表单集数据没有经过验证，我不明白为什么，因为我根本没有接触到物质，只是接触到了外观。

作为一个初学者，我可能错过了一些大事，我提前感谢任何能帮我找出问题的人。

下面是表格和模板：

(用户.表单(

班级学习者表格(forms.ModelForm(：

class Meta:
model = Learner
fields = ['locations', 'organization', 'supervisor', 'intro']

class UserForm(forms.ModelForm):
class Meta:
model = User
fields = ['username', 'first_name', 'last_name', 'birthday', 'email', 'profile_pic']
widgets = {
'birthday': DatePickerInput(format='%Y-%m-%d'), }

LearnerFormSet = inlineformset_factory(User, Learner, form=LearnerForm)

模板

{% extends '_base.html' %}
{% load crispy_forms_tags %}
{% block content %}
<form action="" method="POST" enctype="multipart/form-data">
{% csrf_token %}
{{ form|crispy }}
{{ learner_formset.management_form}}
{% for form in learner_formset %}
{% if forloop.first  %}
{% for field in form.visible_fields %}
{% if field.name != 'DELETE' %}
<label for="id_{{ field.name }}">{{ field.label|capfirst }}</label>
<div id='id_{{ field.name }}' class="form-group">
{{ field.errors.as_ul }}
{{ field }}
</div>
{% endif %}
{% endfor %}
{% endif %}
{% endfor %}
<input class="btn btn-success" type="submit" value="Update"/>
</form>
{% endblock content %}

Answer 1

我通过梳理以前的提交找到了它。问题出在模板上，表单集没有得到验证，因为我忽略了隐藏字段，我听说这是处理表单集时常见的问题。

所以正确的代码是这样的：

{% extends '_base.html' %}
{% load crispy_forms_tags %}
{% block content %}
<form action="" method="POST" enctype="multipart/form-data">
{% csrf_token %}
{{ form|crispy }}
{{ learner_formset.management_form}}
{% for form in learner_formset %}
{% if forloop.first %}
{% comment %} This makes it so that it doesnt show the annoying DELETE checkbox {% endcomment %}
{% for field in form.visible_fields %}
{% if field.name != 'DELETE' %}
<label for="{{ field.name }}">{{ field.label|capfirst }}</label>
<div id="{{ field.name }}" class="form-group">
{{ field }}
{{ field.errors.as_ul }}
</div>
{% endif %}
{% endfor %}
{% endif %}
{% for field in form.visible_fields %}
{% if field.name == 'DELETE' %}
{{ field.as_hidden }}
{% else %}

{# Include the hidden fields in the form #}
{% if forloop.first %}
{% for hidden in form.hidden_fields %}
{{ hidden }}
{% endfor %}
{% endif %}



{% endif %}
{% endfor %}

{% endfor %}

<input class="btn btn-success" type="submit" value="Update"/>
</form>
{% endblock content %}
