I am making a web app with a few pages. On one of the pages, I would like to have a form that looks something like this
However I keep getting an error message saying:
raise CrispyError(‘|as_crispy_field got passed an invalid or
inexistent field’) crispy_forms.exceptions.CrispyError:
|as_crispy_field got passed an invalid or inexistent field
[10/Jul/2019 23:21:12] “GET /year2 HTTP/1.1” 500 148042
Here is my year2.html which appears to be where the error occurs:
{% extends "HelloDjangoApp/layout.html" %}
{% load crispy_forms_tags %}
**HelloDjangoApp/year2.html**
{% block content %}
<form method="post" novalidate>
{% csrf_token %}
<div class="row">
<div class="col-6">
{{ form.name|as_crispy_field }}
</div>
<div class="col-6">
{{ form.email|as_crispy_field }}
</div>
</div>
{{ form.job_title|as_crispy_field }}
{{ form.bio|as_crispy_field }}
<button type="submit" class="btn btn-success">Calculate</button>
</form>
{% endblock %}
For context, here is my views.py
from django.shortcuts import render
from django.http import HttpResponse
from datetime import datetime
from django.shortcuts import render # Added for this step
from django.views.generic import CreateView
from .models import Person
class PersonCreateView(CreateView):
model = Person
fields = ('name', 'email', 'job_title', 'bio')
def index(request):
now = datetime.now()
return render(
request,
"HelloDjangoApp/index.html", # Relative path from the 'templates' folder to the template file
# "index.html", # Use this code for VS 2017 15.7 and earlier
{
'title' : "Exam Results Calculator",
'message' : "Hello!",
'content' : " on " + now.strftime("%A, %d %B, %Y at %X"),
}
)
def about(request):
return render(
request,
"HelloDjangoApp/about.html",
{
'title' : "Simply enter your scores to find out your average",
'content' : "Example app page for Django."
}
)
def year1(request):
return render(
request,
"HelloDjangoApp/year1.html",
{
'title' : "1st Year Average",
'content' : "First Year Stuff"
}
)
def year2(request):
return render(
request,
"HelloDjangoApp/year2.html",
{
'title' : "2nd Year Average",
'content' : "Second Year Stuff"
}
)
def year3(request):
return render(
request,
"HelloDjangoApp/year3.html",
{
'title' : "3rd Year Average",
'content' : "3rd Year Stuff"
}
)
def year4(request):
return render(
request,
"HelloDjangoApp/year4.html",
{
'title' : "4th Year Average",
'content' : "4th Year Stuff"
}
)
# Create your views here.
AND my models.py
from django.db import models
# Create your models here.
class Person(models.Model):
name = models.CharField(max_length=130)
email = models.EmailField(blank=True)
job_title = models.CharField(max_length=30, blank=True)
bio = models.TextField(blank=True)
Please recheck your CBV – PersonCreateView.
Form fields which you are accessing in year2.html are not part of form instance of the View which is handling it.To correct this,
1) Rename your year2.html template to Person_form.html
2) Remove “HelloDjangoApp/year2.html” from year2 function based view.
Hope this helps, thanks.
