在Django管理员自定义命令两个参数 [英] Two arguments in django-admin custom command

问题描述

我有一个工作 Django的管理员自定义的，我用填充我的新的信息的数据库命令。再次，一切正常。

I have a working django-admin custom command that I use to populate my database with new information. Again, everything works.

不过，我现在已经改变了我的模特和略函数接受两个参数作为一个元组 - 名和的姓，而不是只是名

However, I have now changed my models and function slightly to accept two arguments as a tuple - first name and last name, instead of just "name".

previous code以下 - 工作。通过运行manage.py XYZ名1名2 NAME3 ...等（不同ARGS之间的空间）

Previous code below - working. Run using "manage.py xyz name1 name2 name3... etc. (space between the different args)

from django.core.management.base import BaseCommand, CommandError
from detail.models import ABC
from detail.parser import DEF

class Command(BaseCommand):
    args = '<name...>'
    help = 'Populates the ABC class database'

    def handle(self, *args, **options):
        for symbol in args:

            try:
                info = DEF(name)

是否有可能在两个参数传递从Django的管理员自定义命令，其中第二个参数是可选的？ - >即（第一，最后=无）

伪code以下的东西，我想用跑......manage.py XYZ（first1，last1）（first2，last2）LT; - 或者这一些变化

Pseudocode below of what I'd like to run using... "manage.py xyz (first1, last1) (first2, last2) <-- or some variation of this

我已经改变了功能DEF适当地接受这个作为一个独立的功能。我只是不知道我怎么能得到Django的admin命令现在的工作。

I've already changed the function DEF to accept this appropriately as a standalone function. I'm just not sure how I can get the django-admin command working now.

推荐答案

这是完全有可能的，虽然 django.core.management 并没有提供具体的工具来做到这一点。您可以解析通过 ARGS 关键字参数传递的参数。你必须要拿出这样做的语法（定义在帮助语法命令的属性，可能会是一个好主意）。

It's entirely possible, although django.core.management does not provide a specific tool to do so. You can parse the arguments passed via the args keyword argument. You'll have to come up with a syntax for doing so (defining the syntax in the help attribute of the command would probably be a good idea).

假设语法为 firstname.lastname ，或只是姓在省略了姓氏的情况下，你可以这样做：

Assuming the syntax is firstname.lastname, or just firstname in the case that the last name is omitted, you can do something like:

def handle(self, *args, **options):
    for arg in args:
        try:
            first_name, last_name = arg.split('.')
        except ValueError:
            first_name, last_name = arg, None

        info = DEF(first_name, last_name)

和命令的用户可以传递参数，像这样：

And users of the command can pass in arguments like so:

$ python manage.py yourcommand -v=3 john.doe bill patrick.bateman
