问题描述

当我添加数据并单击Submit按钮时，Python Django图像上传不起作用，没有给出任何响应，也没有上传数据库中的任何数据.

models.py首先，我添加了模型文件.

models.pyfisrst of all i add model file.

# Create your models here.
from django.db import models
class Car(models.Model):

    carname=models.CharField(max_length=50)
    carmodel = models.CharField(max_length=50)
    carimage = models.ImageField(upload_to='images/')
    price=models.CharField(max_length=15)
    average=models.CharField(max_length=20)
    gear=models.CharField(max_length=200)
    passengers = models.CharField(max_length=200)
    type=models.CharField(max_length=200)
    Insurance=models.CharField(max_length=200)

    class Meta:
        db_table="car"

forms.py然后我创建一个form.py.

forms.pythen i create a form.py.

from django import forms
from  carapp.models import Car

class CarForm(forms.ModelForm):
    class Meta:
        model=Car
        fields="__all__"

还将这两行添加到settings.py

MEDIA_ROOT =  os.path.join(BASE_DIR, 'media')
MEDIA_URL = '/media/'

urls.py然后我给出方法的路径.

urls.pythen i give a path of method.

from django.contrib import admin
from django.urls import path
from django.conf import settings
from django.conf.urls.static import static
from carapp import carviews
urlpatterns = [
    path('admin/', admin.site.urls),
    #this is for admin user
    path('savecar',carviews.savecar),
    path('showcar', carviews.showcar)
]
if settings.DEBUG:
    urlpatterns += static(settings.STATIC_URL, document_root = settings.STATIC_ROOT)
    urlpatterns += static(settings.MEDIA_URL, document_root = settings.MEDIA_ROOT)

carviews.py

然后我创建了一个API方法.

then I created an API method.

from django.shortcuts import render,redirect
from carapp.forms import CarForm
from carapp.models import Car
from django.core.paginator import Paginator, EmptyPage, InvalidPage

def savecar(request):
    if request.method == "POST":
        form= CarForm(request.POST)
        if form.is_valid():
            try:
                form.save()
                return redirect("/showcar")
            except:
                pass
    else:
        form = CarForm()
    return render(request,"savecar.html",{'form':form})

def showcar(request):
    car_list = Car.objects.all().order_by('-id')

    paginator = Paginator(car_list, 5)
    try:
        page=int(request.GET.get('page','1'))
    except:
        page=1
    try:
        cars= paginator.page(page)
    except(EmptyPage,InvalidPage):
        cars= paginator.page(paginator.num_pages)

    return render(request,"showcar.html",{'cars':cars})

这是savecar.html

this is savecar.html

  <div class="card-body">
            <form method="POST" action="/savecar" >
              {% csrf_token %}
                <div class="form-group">
                  <label for="carname">Car Name</label>
                 <div class="col-sm-4">
                   {{ form.carname }}
                 </div>
                </div>
                <div class="form-group">
                  <label for="carmodel">carmodel</label>
                  <div class="col-sm-4">
                   {{ form.carmodel }}
                 </div>
                </div>
                <div class="form-group">
                  <label for="carimage">carimage</label>
                  <div class="col-sm-4">
                   {{ form.carimage }}
                 </div>
                </div>

                <div class="form-group">
                  <label for="price">price</label>
                  <div class="col-sm-4">
                   {{ form.price }}
                 </div>
                </div>
                <div class="form-group">
                  <label for="average">average</label>
                  <div class="col-sm-4">
                   {{ form.average }}
                 </div>
                </div>
                <div class="form-group">
                    <label for="gear">gear</label>
                    <div class="col-sm-4">
                     {{ form.gear }}
                   </div>
                  </div>

                  <div class="form-group">
                    <label for="passengers">passengers</label>
                    <div class="col-sm-4">
                     {{ form.passengers }}
                   </div>
                  </div>

                  <div class="form-group">
                    <label for="type">type</label>
                    <div class="col-sm-4">
                     {{ form.type }}
                   </div>
                  </div>

                  <div class="form-group">
                    <label for="Insurance">Insurance</label>
                    <div class="col-sm-4">
                     {{ form.Insurance }}
                   </div>
                  </div>

                <button type="submit" class="btn btn-primary">Submit</button>&nbsp;
                <a class="btn btn-primary" href="/showcar">Back</a>
              </form>
          </div>
