我有以下更新settings.py文件的AWK脚本。
原始settings.py
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
}
}
# Password validation
# https://docs.djangoproject.com/en/1.9/ref/settings/#auth-password-validators
AUTH_PASSWORD_VALIDATORS = [
{
'NAME': 'django.contrib.auth.password_validation.UserAttributeSimilarityValidator',
},
{
'NAME': 'django.contrib.auth.password_validation.MinimumLengthValidator',
},
{
'NAME': 'django.contrib.auth.password_validation.CommonPasswordValidator',
},
{
'NAME': 'django.contrib.auth.password_validation.NumericPasswordValidator',
},
]
这是更新DATABASE部分的AWK脚本,它完美运行。
awk 'function pr(sp, k, v){ # prints key-value pair with indentation
printf "%s\047%s\047: \047%s\047,\n",sp,k,v;
}
BEGIN {
db_user = ENVIRON["DB_USER"]
db_pass = ENVIRON["DB_PASS"]
db_name = ENVIRON["DB_NAME"]
}
/sqlite/{ sub(/sqlite[0-9]*/,"mysql",$0) }
/NAME/{ sp=substr($0,1,index($0,"\047")-1);
print sp$1" \047" db_name "\047,";
pr(sp,"USER", db_user); pr(sp,"PASSWORD", db_pass);
pr(sp,"HOST","localhost"); pr(sp,"PORT",""); next
}1'
在AWK脚本之后输出新的settings.py,这也是更新下面的AUTH部分。
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'django',
'USER': 'django',
'PASSWORD': 'django',
'HOST': 'localhost',
'PORT': '',
}
}
# Password validation
# https://docs.djangoproject.com/en/1.9/ref/settings/#auth-password-validators
AUTH_PASSWORD_VALIDATORS = [
{
'NAME': 'django',
'USER': 'django',
'PASSWORD': 'django',
'HOST': 'localhost',
'PORT': '',
},
如何阻止AWK覆盖AUTH部分?

应用以下更新:
awk 'function pr(sp, k, v){ # prints key-value pair with indentation
printf "%s\047%s\047: \047%s\047,\n",sp,k,v;
}
BEGIN {
db_user = ENVIRON["DB_USER"]
db_pass = ENVIRON["DB_PASS"]
db_name = ENVIRON["DB_NAME"]
}
/DATABASES/{ f=1 }/AUTH_PASSWORD_VALIDATORS/{ f=0 }
/sqlite/{ sub(/sqlite[0-9]*/,"mysql",$0) }
/NAME/ && f{ sp=substr($0,1,index($0,"\047")-1);
print sp$1" \047" db_name "\047,";
pr(sp,"USER", db_user); pr(sp,"PASSWORD", db_pass);
pr(sp,"HOST","localhost"); pr(sp,"PORT",""); next
}1' settings.py

小修改可以解决您的问题
/AUTH_PASSWORD_VALIDATORS/{ auth=1 }
!auth && /NAME/{
