Django的“我的模型”表单未保存,因为它无效,但我看不到有什么问题

标签: python django django-forms django-2.0

我对Django非常陌生,部分工作是创建自己的博客模型表单。我遵循了youtube教程的先前示例,但是无法创建自己的博客模型表单。该表单不会保存,因为它无效,并且我已经花了2天时间解决该问题,但找不到错误的地方。

此外,每次我提交表单时,它会将我重定向到另一个我不太了解原因的页面。

请帮助。

我正在使用Django 2.0.7版。

我的模型。py

from django.db import models

class Article(models.Model):
    title   = models.CharField(max_length=120) # Max length required
    content = models.TextField()
    active  = models.BooleanField(default=True)

我的forms.py

from django import forms

from .models import Article

class ArticleForm(forms.ModelForm):
    class Meta:
        model = Article
        fields = [
            'title',
            'content',
            'active'
        ]

我的views.py

from django.shortcuts import render, get_object_or_404, redirect
from .forms import ArticleForm
from .models import Article

def article_list_view(request):
    print("this is article_list.html")
    queryset = Article.objects.all()
    context ={
        "object_list": queryset
    }
    return render(request, "blogs/article_list.html", context)

def article_create_view(request):
    form = ArticleForm(request.POST or None)
    print(ArticleForm.errors)
    if form.is_valid():
        print("Valid form")
        form.save()
    else:
        print("invalid")
        print(ArticleForm.errors)
    context = {
        "form": form
    }
    return render(request, "blogs/article_create.html", context)

article_create.html

{% extends 'base.html' %}

{% block content %}

    <form action='.' method='POST'>{% csrf_token %} 
        {{ form.as_p }}
        <input type='submit' value='Save'>
    </form>

{% endblock %}

urls.py

from django.contrib import admin
from django.urls import include, path

from pages.views import (
    home_view, 
    contact_view, 
    about_view, 
    social_view
    )

from blog.views import (
    article_list_view, 
    article_detail_view,
    article_create_view
    )

urlpatterns = [
    path('products/', include('products.urls')),

    path('', home_view, name='home'),
    path('contact/', contact_view, name='contact'),
    path('about/', about_view, name='product-detail'),
    path('social/', social_view, name='social'),
    path('admin/', admin.site.urls),

    #blog paths
    path('articles/', article_list_view, name = 'articles'),
    path('articles/detail/<int:id>', article_detail_view, name = 'article-detail'),
    path('articles/create', article_create_view, name = 'article-create'),

]

这显示在服务器的命令提示符下:

Django version 2.0.7, using settings 'trydjango.settings'
Starting development server at http://127.0.0.1:8000/
Quit the server with CTRL-BREAK.
<property object at 0x000001ED94386458>
invalid
<property object at 0x000001ED94386458>
[18/Apr/2019 22:33:51] "GET /articles/create HTTP/1.1" 200 920
this is article_list.html
[18/Apr/2019 22:34:02] "POST /articles/ HTTP/1.1" 200 668

一旦我进入article / create或article_create.html,就会出现<property object at 0x000001ED94386458>

1)您不应在上使用.errors

ArticleForm.errors

应该是

form.errors

2)您应该在视图中分离GET和POST请求。

def article_create_view(request):
    if request.method == "POST":
        form = ArticleForm(request.POST)            
        if form.is_valid():
            print("Valid form")
            form.save()
        else:
            print("Invalid form")
            print(form.errors)        
    else:
        form = ArticleForm()

    context = {"form": form)

    return render(request, "blogs/article_create.html", context)

您的表单应该发布到"",而不是"."

<form action='' method='POST'>{% csrf_token %} 

或者,请确保您最初导航到/articles/create/,而不是没有最后斜杠的/articles/create。 (尽管通常,内置的CommonMiddleware将负责使用斜杠重定向到路径-您是否有将APPEND_SLASH设置设置为False的可能性?)
