Question

models.py

from PIL import Image
class Award_list(models.Model):
    award_id=models.AutoField(primary_key=True)
    award_name=models.CharField(max_length=50,blank=False)
    award_image = models.ImageField(upload_to='award_pics',default='award.jpg')

    def __str__(self):
        return f'{self.award_name} award'
    def save(self,*args,**kwargs):
        super().save(*args,**kwargs)

        img = Image.open(self.award_image.path)

        if img.height > 300 or img.width > 300:
            output_size = (300, 300)
            img.thumbnail(output_size)
            img.save(self.award_image.path)
    class Meta:
        verbose_name_plural = 'Award'

forms.py

from django import forms
from movies_list.models import Award_list

class Create_Award_list_form(forms.ModelForm):
    class Meta:
        model=Award_list
        fields=['award_name','award_image']

views.py

from .models import Award_list
from .forms import Create_Award_list_form

def Award_list_create(request):
    form=Create_Award_list_form(request.POST,request.FILES or None)
    if form.is_valid():
        # print(request.POST['award_name'])
        form.save()
    else:
        print(form.errors)
    context={
        "hell":'sanjeet',
        "form":form
    }   
    return render(request,'movies_list/award_list_create.html',context)

urls.py

urlpatterns = [
    path('movies/awards/new/',Award_list_create,name="award-list-create"),

]

award_list_create.html

{% extends "users/base.html" %}
{% load crispy_forms_tags %}
{% block content %}
    <div class="content-section">
        <form method="POST">
            {% csrf_token %}
            <fieldset class="form-group">
                <legend class="border-bottom mb-4">Blog Post</legend>
               {{form.as_p}}
               {{hell}}
            </fieldset>
            <div class="form-group">
                <button class="btn btn-outline-info" type="submit">Submit</button>
            </div>
        </form>
    </div>
{% endblock content %}

这所有代码行都可以在管理页面上正常工作，并选择将图像保存到MEDIA_URL / awards_pics文件中，但是当我创建基于模型的表单时，即使选择了.html表单中的图像，它也会选择默认选项。

Answer 1

<form method="POST" enctype="multipart/form-data">

在表单标签中添加enctype="multipart/form-data"，以便您可以从html上传图像

创建ModelForm时，ImageField不起作用
