将此jquery.cookie写入SQLite数据库的最佳方法是什么？ （当然没有形式）
$ .cookie（'cart'）=
"[{"name":"Cinnamon bun","image":"/static/images/items/bakery/cinnamon_bun.jpg", "price":" 5 uah","quantity":"2","alias":"cinnamon"}, {"name":"Croissant","image":"/static/images/items/bakery/croissant.jpg", "price":" 10 uah","quantity":"1","alias":"croissant"}, {"name":"Donut","image":"/static/images/items/bakery/donuts.jpg", "price":" 7 uah","quantity":"4","alias":"donut"}, {"name":"Chocolate chip cookies","image":"/static/images/items/bakery/cookies.gif", "price":" 30 uah","quantity":"2","alias":"cookies"}]"What is the best way to write this jquery.cookie to SQLite database? (without form of course)
$.cookie('cart') =
"[{"name":"Cinnamon bun","image":"/static/images/items/bakery/cinnamon_bun.jpg", "price":" 5 uah","quantity":"2","alias":"cinnamon"}, {"name":"Croissant","image":"/static/images/items/bakery/croissant.jpg", "price":" 10 uah","quantity":"1","alias":"croissant"}, {"name":"Donut","image":"/static/images/items/bakery/donuts.jpg", "price":" 7 uah","quantity":"4","alias":"donut"}, {"name":"Chocolate chip cookies","image":"/static/images/items/bakery/cookies.gif", "price":" 30 uah","quantity":"2","alias":"cookies"}]"最满意答案
它们有两种可能性：
使用simple_tag（自定义模板标签）多亏了它，您不必担心URL用户将访问哪个。 下面写的代码将在每个请求中运行。
Docs HERE 。 （注意：它适用于1.8版本，如果您使用的是不同版本的Django，请不要忘记切换文档）。
您的代码应如下所示:(在templatetags /文件夹中的python文件中）
@register.simple_tag(takes_context=True) def your_name_of_this_function(context): """ What is this tag about? (your comment) """ request = context["request"] # Get cookies cookies = request.cookies["cart"] # Your codes for writing new lines into your models into your SQlite DB # if they are not in DB (the cookies) ...更多关于此处的请求。 注意：cookie采用字典形式
然后将此行添加到顶部的“base.html”：
{% load your_name_of_your_tag_script_without_dot_py %}和某处（仍然是“base.html”）这个:(例如）
{% name_of_your_function_from_that_script %}正如我所说，这段代码将在每个请求中运行simple_tag。
在views.py中的1个函数中没有simple_tag在这里，用户的另一种方式是必须点击特定的URL才能将cookie写入数据库。
代码：
def your_function(request): """ blablabla """ cookies = request.cookies["cart"] # Codes for creating a new line into your models ...They are 2 possibilities:
using a simple_tag (custom template tags)Thanks to it you don't have to worry which a URL user will visit. Codes written below will be run every single request.
Docs HERE. (Note: it's for the version 1.8, if you are using a different version of Django, don't forget switch the docs).
Your codes should look like this: (in a python file inside templatetags/ folder)
@register.simple_tag(takes_context=True) def your_name_of_this_function(context): """ What is this tag about? (your comment) """ request = context["request"] # Get cookies cookies = request.cookies["cart"] # Your codes for writing new lines into your models into your SQlite DB # if they are not in DB (the cookies) ...More about requests HERE. Note: cookies are in the form of dictionary
Then add this line to your "base.html" at the top:
{% load your_name_of_your_tag_script_without_dot_py %}and somewhere (still "base.html") this: (e. g. )
{% name_of_your_function_from_that_script %}This code will run the simple_tag every single request as I said.
without simple_tag within 1 function in your views.pyHere the other way around a user have to hit a specific URL in order to write cookies into your database.
Codes:
def your_function(request): """ blablabla """ cookies = request.cookies["cart"] # Codes for creating a new line into your models ...更多推荐
