在 Django 中提交表单和调试

问：

我想创建一个表单，以便用户可以注册产品。 但是，表单已创建，但未提交。 原因是什么？

并且在选择状态时，产品页面上记录的不是旧版本或新版本，而是 n 和 o。 为什么？

views.py：

# create list
    @login_required(login_url="login")
    def create_list(request):
        if request.method == "POST":
            item = List()
            item.user = request.user.username
            item.title = request.POST["create_list_title"]
            item.category = request.POST["category"]
            item.status = request.POST["status"]
            item.description = request.POST["create_list_description"]
            item.first_bid = request.POST["create_list_initial_bid"]
            item.image_url = request.POST["img_url"]
            item.save()
            return redirect("index")
        return render(request, "auctions/create_list.html")`

create_list.html：

{% extends "auctions/layout.html" %}
    
    {% block body %}
        <h2 id = "h2">Create List</h2>
        <div>
            <form  method="POST">
                {% csrf_token %}
                <a id ="h4">Title :    <input  required placeholder="Title" autofocus type="text" name="create_title"/>
                <a id = "h4">Category : <input required placeholder="Category" type="text" name="category"/></a>
                <a id = "h4">Description : <textarea placeholder="Add Description" required type="text" name="create_desc"></textarea></a>
                <a id = "h4">Starting bid : <input required placeholder="Starting bid" type="number" name="create_initial_bid"/></a>
                <a id = "h4">Status : <input required placeholder="Status" type="text" name="status"/></a>
                
                <form  action="upload.php" method="post" enctype="multipart/form-data">
                    <label id="h4" for="fileUpload">Upload Image:</label>
                    <input id="h4" type="file" id="fileUpload" name="fileUpload">
                </form><br>
    
                <a id = "h4">Image_url :<input placeholder="Image URL" type="text" name="img_url"/></a><br>
    
                <button id = "button" class="btn btn-outline-primary" type="submit">Submit</button>
            </form>   
        </div>
          
    {% endblock %}

models.py：

class List(models.Model):
        choice = (
            ("n", "new vertion"),
            ("o", "old vertion")
        )
        user = models.CharField(max_length=64)
        title = models.CharField(max_length=64)
        description = models.TextField()  
        category = models.CharField(max_length=64)      
        first_bid = models.DecimalField(max_digits=10, decimal_places=2)   
        image = models.ImageField(upload_to="img/", null=True)      
        image_url = models.CharField(max_length=228, default = None, blank = True, null = True)
        status = models.CharField(max_length=1, choices= choice)
        active_bool = models.BooleanField(default = True)
