在Pycharm中以DEBUG模式在Django服务器上跳过系统检查 [英] Skip system checks on Django server in DEBUG mode in Pycharm

问题描述

我正在Pycharm中以调试模式运行django应用程序。
每次更改某些代码系统时，都会执行检查。

I am running django application in Pycharm in DEBUG mode. Each time when i change some code system checks are performed.

pydev debugger: process 2354 is connecting

Performing system checks...

是否有任何方法可以跳过系统检查/速度

Is there any way to skip system checks/speed up this checks?

更新：我想在代码更改后禁用系统检查，因为它们太慢了。

UPDATE: I want to disable system checks after changes in code, because they are too slow.

问题

不幸的是，没有命令行参数或设置，您只能打开才能将其关闭 runserver 中的检查。 通常，有-skip-checks 选项可以关闭系统检查，但对于没有用处runserver 。

The Problem

Unfortunately, there's no command-line argument or setting you can just turn on in order to turn off the checks in runserver. In general, there's the --skip-checks option which can turn off system checks but they are of no use for runserver.

如果您阅读 runserver 命令的代码，则会看到它实际上会忽略 requires_system_checks 和 requires_migration_checks 标志，而是显式调用 self.check（）和 self.check_migrations（）在其 inner_run 方法，无论如何：

If you read the code of the runserver command, you see that it essentially ignores the requires_system_checks and requires_migration_checks flags but instead explicitly calls self.check() and self.check_migrations() in its inner_run method, no matter what:

def inner_run(self, *args, **options):
    [ Earlier irrelevant code omitted ...]

    self.stdout.write("Performing system checks...\n\n")
    self.check(display_num_errors=True)
    # Need to check migrations here, so can't use the
    # requires_migrations_check attribute.
    self.check_migrations()

    [ ... more code ...]

解决方案

您可以做的是派生您自己的 run 命令，它使用 runserver 命令，但会覆盖执行检查的方法：

A Solution

What you could do is derive your own run command, which takes the runserver command but overrides the methods that perform the checks:

from django.core.management.commands.runserver import Command as RunServer

class Command(RunServer):

    def check(self, *args, **kwargs):
        self.stdout.write(self.style.WARNING("SKIPPING SYSTEM CHECKS!\n"))

    def check_migrations(self, *args, **kwargs):
        self.stdout.write(self.style.WARNING("SKIPPING MIGRATION CHECKS!\n"))

您需要将其放在< app> /management/commands/run.py 下，其中< app> 是适合该应用程序的任何命令。然后您可以使用 ./ manage.py run 调用它，您将得到类似的东西：

You need to put this under <app>/management/commands/run.py where <app> is whatever appropriate app should have this command. Then you can invoke it with ./manage.py run and you'll get something like:

Performing system checks...

SKIPPING SYSTEM CHECKS!

SKIPPING MIGRATION CHECKS!
