QA

***** like点赞问题 *****
index.js里面的url改为  url: '/insta/like/',
InstaDemo/urls.py中的url改为  path('insta/', include('Insta.urls')),
Insta/urls.py中的url改为  path('like/', addLike, name='addLike'),

***** 'AnonymousUser' object is not iterable *****
在Insta/views.py里面的PostListView的get_queryset开头加上
>>> if not self.request.user.is_authenticated:
>>>     return 
先要验证用户是否登陆,再执行接下来的步骤

***** django-imagekit *****
这个包安装的时候配置的路径或者环境变量的问题,就在本地环境和当前的虚拟环境都使用`pip install django-imagekit`或者`pip3 install django-imagekit`安装这个库

***** Python环境问题 *****
在Shell中分别执行`python -V`, `python3 -V`, `pip -V`, `pip3 -V`,查看结果
查看Python 3对应的pip版本,记住是pip还是pip3,后面使用这个安装lib

***** vscode自动补全问题 *****
安装自动补全和语法检查之类的vscode插件就好,尝试:jinja、Better Jinja、Python Template Snippets等插件

***** create post 限定当前用户的问题 *****
view里面的PostCreateView里面加个表单验证就好了,还有修改html这里提交的时候把form表单这里的author去掉
"""py
class PostCreateView(CreateView):
    model = Post
    template_name = "make_post.html"
    fields = '__all__'

    def form_valid(self, form):
        form.instance.author = self.request.user
        return super().form_valid(form)
"""

https://github.com/daidai21/InstaDemo/blob/master/templates/make_post.html

或者

PostCreateView中添加form_valid和修改fields为"""fields = {'title', 'image'}""

***** 安装虚拟环境使用pipenv遇到问题 *****
放弃使用虚拟环境,也就是pipenv工具,直接使用pip(或者pip3,根据自己的环境配置)
"""
pip install -r requirements.txt
"""
执行上边的命令直接安装对应的所有依赖包
