Crispy_forms.Exceptions.CrispyError: |as_crispy_field 传递了无效或不存在的字段 - models.ForeignKey
我正在尝试为现有模型创建前端数据输入页面。但是,当单击该链接时,我收到一个错误:
crispy_forms.exceptions.CrispyError: |as_crispy_field got passed an invalid or inexistent field
需要明确的是,从 Django Admin 添加数据完全没有问题。
在这里查看了一些已回答的问题后,确实强调了我认为可能存在问题的地方,但它断章取义,没有提供太多解释。
我正在尝试为与外键对应的用户创建一个前端输入表单。

有人在另一篇文章中提到表单应与声明的表单名称相关联 { { form.shift1_mod|as_crispy_field }}
所以它实际上应该是 {{ create_new_handoff_form.shift1_mod|as_crispy_field }}
但我尝试改变这个并且仍然遇到同样的问题,另外,尽管表单的名称是attention_form,但另一个模型表单仅适用于表单即可正常工作。
有谁有任何想法或可以指出我正确的方向吗? :)
I'm trying to create a frontend data entry page for an existing model. However, when clicking the link, I get an error:
crispy_forms.exceptions.CrispyError: |as_crispy_field got passed an invalid or inexistent field
Just to be clear, adding the data from Django Admin works with no issues at all.
Having looked through a number of answered questions here, one did highlight what I believe could be problem, but it was out of context and did not provide much of an explanation.
I am trying to create a frontend entry form for users that corresponds with a foreign key.
models.py
class NewHandoff(models.Model):
handoff_pk = models.AutoField(primary_key=True)
handoff_date = models.DateField(auto_now_add=True,verbose_name="Handoff Date")
shift1_pri = models.ForeignKey(Engineer,on_delete=models.CASCADE,verbose_name="Shift 1 Primary")
shift1_sec = models.ForeignKey(Engineer,on_delete=models.CASCADE,verbose_name="Shift 1 Secondary")
def __str__(self):
return f"{self.handoff_date}"
class Meta:
verbose_name_plural = 'Handoffs'
# New Handoff Form
class NewHandoffForm(forms.ModelForm):
class Meta:
model = NewHandoff
fields = ['shift1_pri','shift1_sec']
views.py
from django.shortcuts import redirect, render
from django.views import View
from django.contrib.auth.mixins import LoginRequiredMixin
from django.http.response import HttpResponse
from django.contrib import messages
from .models import AttentionForm, NewHandoffForm
# Handoff View Page
class NewHandoffView(LoginRequiredMixin,View):
def get(self, request):
greeting = {}
greeting['heading'] = "New Handoff"
greeting['pageview'] = "Handoff"
return render (request,'handoff/handoff-new.html')
def post(self, request):
if request.method == "POST":
if "add-new-handoff-button" in request.POST:
create_new_handoff_form = NewHandoffForm(request.POST)
create_new_handoff_form.save()
return redirect("/handoff/handoff-create")
handoff-new.html
{% extends 'partials/base.html' %}
{% load static %}
{% load humanize %}
{% load crispy_forms_tags %}
{% block extra_css %}

<div class="row">
<div class="col-12">
<div class="card">
<div class="card-body">
<!-- New Form -->
<form method="POST">
{% csrf_token %}
<div class="row">
<div class="row-fluid pb-1">
<!-- Field 1 -->
<div class="mb-3">

</div>
<!-- End of Field 1 -->
</div>
</div>
<div class="d-flex flex-wrap gap-2">
<button type="submit" class="btn btn-primary waves-effect waves-light" name="add-new-handoff-button">Create New Handoff</button>

Someone mentioned in another post that forms should correlate with the declared form name {{ form.shift1_mod|as_crispy_field }}
so it should actually be {{ create_new_handoff_form.shift1_mod|as_crispy_field }}
but I have tried changing this and still get the same problem, plus, another model form works fine with just form despite the name of the form being attention_form.
Does anyone have any idea or can point me in the right direction? :)

您没有通过模板中的上下文传递表单。当您继承
View
时,请在 get() 中添加以下行,然后在 post() 方法中适当添加以下行:此外,在 get 函数中的 render 之后有一个空格。我希望这是这里的拼写错误,但不是您的代码中的拼写错误。
You are not passing the form through the context in the template. As you are inheriting
View
, Add the following line in the get() and afterwards in the post() method appropriately:Also, you have a space after render in the get function. I hope this is a typo here, but not in your code.
