Django makemessages获取自定义可翻译字符串

Question

在我的Django项目中，我使用Vue + vue-gettext作为i18n。

要制作可翻译的字符串，我的.vue文件中包含以下代码：

<translate>Hello %{name}</translate>

<a href="..." v-translate>Click here</a>

（使用翻译标签和v-translate属性）

有没有办法配置manage.py makemessages来解析这段代码？默认情况下，它不会查看.vue文件或解析此i18n代码格式。

基本上我最终得到了一个Makefile - 从vue文件中提取消息然后将其与django合并

# On OSX the PATH variable isn't exported unless "SHELL" is also set, see: http://stackoverflow.com/a/25506676
SHELL = /bin/bash
NODE_BINDIR = ./node_modules/.bin
export PATH := $(NODE_BINDIR):$(PATH)

INPUT_DIR = static/js
# Where to write the files generated by this makefile.
OUTPUT_DIR = .

# Available locales for the app.
LOCALES = en nl fr

# Name of the generated .po files for each available locale.
LOCALE_FILES ?= $(patsubst %,$(OUTPUT_DIR)/locale/%/LC_MESSAGES/app.po,$(LOCALES))

GETTEXT_HTML_SOURCES = $(shell find $(INPUT_DIR) -name '*.vue' -o -name '*.html' 2> /dev/null)
GETTEXT_JS_SOURCES = $(shell find $(INPUT_DIR) -name '*.vue' -o -name '*.js')
