for 循环在 Django 模板中不起作用（在 table 标记内）

Question

我正在尝试在我的 html 模板中创建一个 table ，但是当我写 <td>{{project.title}}</td> 它不起作用！实际上当我使用 {{x}} 我没有输出！我真的不知道我的模板里面有什么问题...

html 模板：

{% extends 'main.html' %}


{% block content %}
 
<h1>Projects</h1>


<table>
    <tr>
        <th>ID</th>
        <th>Project</th>
        <th>Votes</th>
        <th>Ratio</th>
        <th></th>
    </tr>
    {% for project in Projects %}
    <tr>
        <td>{{project.id}}</td>
        <td>{{project.title}}</td>
        <td>{{project.vote_total}}</td>
        <td>{{project.vote_ratio}}</td>
        <td>{{project.created}}</td>
        <td><a href="{% url 'project' project.id %}">View</a></td>
    </tr>
    {% endfor %}
</table>

{% endblock content %}

models.py:

from django.db import models
import uuid

from django.db.models.deletion import CASCADE 
# Create your models here.


class Project(models.Model):
    title = models.CharField(max_length=200)
    descripeion = models.TextField(null=True, blank=True)
    demo_link = models.CharField(max_length=1000, null=True, blank=True)
    source_link = models.CharField(max_length=1000, null=True, blank=True)
    tags = models.ManyToManyField('Tag', blank=True)
    vote_total = models.IntegerField(default=0, null=True, blank=True)
    vote_ratio = models.IntegerField(default=0, null=True, blank=True)
    created = models.DateTimeField(auto_now_add=True)
    id = models.UUIDField(default=uuid.uuid4, unique=True, primary_key=True, 
    editable=False)

    def __str__(self) -> str:
        return self.title    

class Review(models.Model):
    VOTE_TYPE = (
        ('up', 'Up Vote'),
        ('down', 'Down Vote')
    )
    # owner =
    project = models.ForeignKey(Project, on_delete=CASCADE)
    body = models.TextField(null=True, blank=True)
    value = models.CharField(max_length=200, choices=VOTE_TYPE)
    created = models.DateTimeField(auto_now_add=True)
    id = models.UUIDField(default=uuid.uuid4, unique=True, primary_key=True, 
    editable=False)

    def __str__(self) -> str:
        return self.value

class Tag(models.Model):
    name = models.CharField(max_length=200)
    created = models.DateTimeField(auto_now_add=True)
    id = models.UUIDField(default=uuid.uuid4, unique=True, primary_key=True, 
    editable=False)

    def __str__(self) -> str:
        return self.name

views.py:

from django.shortcuts import render
from django.http import HttpResponse
from .models import Project


projectsList = [
    {
        'id':'1',
        'title':'Ecommerce Website',
        'description':'Fully functional ecommerce website'
    },
    {
        'id':'2',
        'title':'Portfolio Website',
        'description':'This was a project where i built out my 
         portfolio'
    },
    {
        'id':'3',
        'title':'Social network',
        'description':'owesome open source project i am still 
         working'
    },
]


def projects(request):
    projects = Project.objects.all()
    context = {'projects': projects}
    return render(request, 'projects/projects.html',context)

def project(request, pk):
    projectObj = Project.objects.get(id=pk)
    return render(request, 'projects/single-project.html', 
                                  {'project': projectObj})

admin.py:

from django.contrib import admin
from .models import Project, Review, Tag

admin.site.register(Project)
admin.site.register(Review)
admin.site.register(Tag)

the files and folders

有人知道我做错了什么吗？

当您使用小写“p”在上下文处理器中传递项目时，将其设为

{% for project in projects %}

在您的模板中。

for loop doesn't work in Django template (inside of table tag)
