Django，模型表格未在数据库中保存数据

Posted 2021-05-07

我是django的新手，我创建了一个表单来将数据保存到我的数据库中，但是它无法正常工作，我没有出现错误，但是数据未在数据库中发送。感谢您的帮助！

views.py

@login_required()
def data(request):
    if request.POST == "POST":
        form = CreatePost(request.POST)
        if form.is_valid():
            form.instance.author = request.user
            form.save()
            return redirect(data)
    else:
        form = CreatePost()
    context = {
        "form": form
    }
    return render(request, "sms/data.html", context)

forms.py

class CreatePost(forms.ModelForm):

    class Meta:
        model = Post
        fields = ["title", "content"]

models.py

class Post(models.Model):
    title = models.CharField(max_length=100)
    content = models.TextField()
    author = models.ForeignKey(User, on_delete=models.CASCADE)


    def __str__(self):
        return self.title

data.html

<form method="POST">
    {% csrf_token %}
    {{ form|crispy }}
      <pre></pre>
    <button class="btn btn-outline-info" type="submit" value="Submit">Data</button>
</form>

答案

尝试这样

@login_required()
def data(self, request):
 if request.method == "POST": #this line
    form = CreatePost(request.POST)
    if form.is_valid():
        post = form.save(commit=False) #new line
        post.author = self.request.user #this line
        post.save() #this line
        return redirect(data)
else:
    form = CreatePost()
context = {
    "form": form
}
return render(request, "sms/data.html", context)
