I am trying to use a ModelForm to save objects to the database. I have also added an ImageField. Through the admin panel, I am easily able to add objects with an image but every time I submit the ModelForm with the same image it doesn't get saved and returns an error saying "This field is required" (screenshot and code attached). How do I fix this?
Here's a screenshot of the error:
The models file:
from django.db import models
from django.conf import settings
class Book(models.Model):
rel_user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, verbose_name="Posted By")
image = models.ImageField(verbose_name="Image", upload_to="static/Books/img")
title = models.CharField(max_length=256, verbose_name="Title")
description = models.TextField(verbose_name="Description")
price = models.IntegerField(verbose_name="Price")
state = models.CharField(max_length=256, verbose_name="State")
city = models.CharField(max_length=256, verbose_name="City")
neighbourhood = models.CharField(max_length=256, verbose_name="Neighbourhood")
phone = models.IntegerField(verbose_name="Phone Number")
def __str__(self):
return self.title + f" ({self.rel_user.username})"
The forms file:
from django.forms import ModelForm
from Books.models import Book
class BookForm(ModelForm):
class Meta:
model = Book
fields = ['image', 'title', 'description', 'price', 'state', 'city', 'neighbourhood', 'phone']
The views file:
from django.shortcuts import render, redirect
from Books.forms import BookForm
from django.contrib import messages
from Books.models import Book
def sell(request):
if request.method == "GET":
form = BookForm()
else:
form = BookForm(request.POST)
form.instance.rel_user = request.user
if form.is_valid():
form.save()
messages.success(request, "Successfully added!")
return redirect('sell')
else:
messages.error(request, "Please fill in all the fields.")
return render(request, 'Books/sell.html', {"form": form})
The HTML code:
<div class="container" style="padding: 2%">
<div class="row">
<div class="col-md-4 col-sm-4 col-xs-12"></div>
<div class="col-md-4 col-sm-4 col-xs-12" style="background-color: rgba(256, 256, 256, 0.8);">
{% if messages %}
{% for message in messages %}
<div class="alert alert-primary" role="alert" style="margin-top: 2%;">
{{ message }}
</div>
{% endfor %}
{% endif %}
<form method="POST" action="{% url 'sell' %}">
{% csrf_token %}
<fieldset class="form-group">
<legend class="border-bottom mb-4">Sell A Book</legend>
{{ form|crispy }}
</fieldset>
<div class="form-group">
<button class="btn btn-outline-info" type="submit">Submit
</button>
</div>
</form>
</div>
<div class="col-md-4 col-sm-4 col-xs-12"></div>
</div>
</div>
