我正在处理 1 周的表格,但无法解决我的问题。可能我忽略了其他眼睛容易发现的东西,但完全不知道该怎么做。我通过开始构建表单来识别问题。我不得不使用render表单,每次尝试都失败了。我能够连接数据库并在 html 页面中显示数据,但是每当我使用它render而不是render_to_response它时都会失败。据我所知,我不得不使用render发布请求。不仅适用于形式,render也不适用于所有人。即使是简单的:def home(request): context = {'foo': 'bar'} return render(request, 'main.html', context)

模型.py

class ModuleNames(models.Model):
    ModuleName = models.CharField(max_length = 50)
    ModuleDesc = models.CharField(max_length = 256)
    ModuleSort = models.SmallIntegerField()
    isActive = models.BooleanField()
    ModuleType = models.ForeignKey(ModuleTypes, on_delete=models.CASCADE, null = True)
    slug = models.SlugField(('ModuleName'), max_length=50, blank=True)

class Meta:
    app_label = 'zz'
def __unicode__(self):
    return self.status

表格.py

from django import forms
from MyApp.models import ModuleNames

class ModuleForm(forms.ModelForm):
    moduleName = forms.CharField(label='Module Name', max_length=50)
    ModuleDesc = forms.CharField(max_length = 256)
    ModuleSort = forms.IntegerField()
    isActive = forms.BooleanField()
    ModuleType = forms.IntegerField()

class Meta:
    model = ModuleNames
    fields =('moduleName','ModuleDesc','ModuleSort','isActive','ModuleType')

        posts = ModuleNames.objects.all()
        args = {'form': form, 'posts': posts }
        return render(request, template_name, args) #This part is showing data when i use render_to_response. But after clicking Save button on html page, it will give below first error.

    if request.method == 'POST':
        form = ModuleForm(request.POST)
        if form.is_valid():
            form.pop('csrfmiddlewaretoken', None)
            post = form.save(commit=False)
            post.save()
            text = form.cleaned_data['post']
            form = ModuleForm()
            args = {'form': form, 'text': text}
            return render(request, template_name, args)
  1. 使用render_to_response Forbidden (403) CSRF 验证失败时出现的错误。请求中止。

    帮助 失败原因:CSRF 令牌丢失或不正确。

  2. render当我用于任何功能时出错

您缺少表单csrf_token中的 the addnewmodule.html,因此,您可以返回addnewmodule.html表单并像这样{% csrf_token %}在标签下方添加form action="" method="POST"

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