小编Pra*_*aur的帖子

我有以下两个清单:

first = [1,2,3,4,5]
second = [6,7,8,9,10]

现在我想将两个列表的项目添加到新列表中.

输出应该是

third = [7,9,11,13,15]

我想在某些条件下退出Lua脚本的执行.示例:

content = get_content()
if not content then   
-- ( Here i want some kind of exit function )
next_content = get_content()
--example there can lot of further checks

在这里我希望如果我没有得到内容我的脚本假设终止是不应该去检查下一个.

我想从我的lua文件中运行一个python脚本.我怎样才能做到这一点？

例:

Python代码

#sum.py file
def sum_from_python(a,b)
    return a+b 

Lua代码

--main.lua file
print(sum_from_python(2,3)) 

就像在python中一样,我们有pass语句.

def calcu():
    pass

在Lua有这样的声明吗？我想要做

if connect then 
    pass

我在lua有一张桌子

test = {1,2,4,2,3,4,2,3,4,"A", "B", "A"}

我想删除表中的所有重复元素.
输出应该是

test = {1,2,4,3,"A","B"}

编辑:

我的尝试:

> items = {1,2,4,2,3,4,2,3,4,"A", "B", "A"}
> flags = {}
> for i=1,table.getn(items)  do
if not flags[items[i]] then
      io.write(' ' .. items[i])
      flags[items[i]] = true
   end
>> end
 1 2 4 3 A B>

现在工作正常.感谢您的回答和评论.

我有一个Person存储人员详细信息的模型.

class Person(models.Model):
    first_name = models.CharField(max_length=100)
    last_name = models.CharField(max_length=100)    
    birthdate = models.DateField()

我也有模特PersonLogs来存储人的活动日志.

class PersonLogs(models.Model):
    person = models.ForeignKey(Person)
    time = models.DateTimeField(auto_now_add=True)

我正在使用Django Serializer将Person对象作为响应返回JSON格式.

from django.core import serializers
data = serializers.serialize("json", Person.objects.all())

输出:

{
    "model": "store.person",
    "fields": {
        "first_name": "Douglas",
        "last_name": "Adams",
        "birth_date": "1952-03-11",
    }
}

现在我想回到PersonLogsJSON回复.

预期产出:

{
    "model": "store.person",
    "fields": {
        "first_name": "Douglas",
        "last_name": "Adams",
        "birth_date": "1952-03-11",
        "personlogs": [['2015-06-09 15:42:58.861540'], ['2014-06-09 15:42:58.861540'], [2013-06-09 15:42:58.861540]]
    }
}

我查看了官方文档,但我没有得到任何帮助.链接

我有一张桌子,我在其中传递名字:

names = {'Sachin', 'Ponting', 'Dhoni'}

在其他表格中,我传递的是国名:

country = {"India", "Australia", "India"}

我想要输出表:

out_table = {Sachin="India", Ponting="Australia", Dhoni="India"}

如果请求URL是

test.com/gifts.

 ngx.var.uri

/gifts/

test.com/gifts

 location /gifts {
                    try_files $uri @url_change;
                }


                location @url_change {
                default_type text/html;
                content_by_lua '

                        ngx.say(ngx.var.uri)
                         ';
                }

我正在使用django_select2和我的夹层项目.
根据文档,我遵循流程.

#step1 :
pip install django-select2
#Step2 :
url(r'^select2/', include('django_select2.urls')),

但是,当我重新加载我的网站时,我得到了错误

我是nginx的新手,lua .i安装了Openresty.下面是我在nginx.conf文件中的代码.

server{
      location /hellolua {
      default_type 'text/plain';

        ngx.say("Hello, ", name, "!")    ';
        }
       }

当我跑步的时候
