Flask-Assets在本地工作，但不在Heroku上 [英] Flask-Assets working locally but not on Heroku
问题描述
我正在修改
我已经通过使用包含以下内容的文档根中的.bowerrc文件来设置bower以在静态根目录下安装前端依赖项： directory：myflaskapp / static / bower_components}
我修改了myflaskapp / assets.py文件：
pre $ from flask_assets import Bundle，Environment
import os
css = Bundle（
libs / bootstrap / dist / css / spacelab / bootstrap.css，
bower_components / eonasdan-bootstrap-datetimepicker / build / css / bootstrap-datetimepicker。 css，
css / style.css，
css / home.css，
＃css / style.css，
filters =cssmin，
output =public / css / common.css
）
js = Bundle（
libs / jQuery / dist / jquery.js，
libs / bootstrap / dist / js / bootstrap.js，
bower_components / moment / moment.js，
bower_components / eonasdan-bootstrap-datetimepicker / build / js / bootstrap-datetimepicker .min.js，
js / plugins.js，
filters ='jsmin'，
output =public / js / common.js
）
资产= E nvironment（）
assets.register（js_all，js）
assets.register（css_all，css）
myflaskapp / app.py初始化资源：
from flask import Flask，render_template
from myflaskapp.assets import assets
：param config_object：要使用的配置对象。
app = Flask（__ name__）
app.config.from_object（config_object）
register_extensions（app）
register_blueprints（app）
register_errorhandlers （app）
返回应用程序
def register_extensions（app）：
assets.init_app（app）
$ b $ def register_blueprints（app）：
app.register_blueprint（public.blueprint）
app.register_blueprint（user.blueprint）
在myflaskapp / settings.py中，在测试过程中，我已经设置了：
ASSETS_DEBUG = True＃不要捆绑/缩小静态资产
本地控制台中没有错误，在heroku上，我得到一个内部服务器错误。日志：

正如你可以看到的它是在那里的顶部截图。如何解决这个问题？
注意：我一直在寻找 https://github.com/mitsuhiko/flask/issues/348 ，这可能与此有关。
尝试检查.gitignore，生成经常被忽略，这将排除你的静态文件在这里：bower_components / eonasdan-bootstrap-datetimepicker / build / *
I'm working to modify a cookiecutter Flask app. I'm working locally on WIN7 and attempting to deploy to heroku. I'm currently trying to add a datepicker to a page. I've found https://eonasdan.github.io/bootstrap-datetimepicker/. The structure of myflaskapp:
I've set up bower to install the front end dependencies under the static root by using a .bowerrc file in the document root containing:
{ "directory" : "myflaskapp/static/bower_components" }
This cookiecutter uses flask-assets to manage the project assets. Following https://adambard.com/blog/fresh-flask-setup/ I've modified myflaskapp/assets.py file :
from flask_assets import Bundle, Environment
import os
css = Bundle(
"libs/bootstrap/dist/css/spacelab/bootstrap.css",
"bower_components/eonasdan-bootstrap-datetimepicker/build/css/bootstrap-datetimepicker.css",
"css/style.css",
"css/home.css",
# "css/style.css",
filters="cssmin",
output="public/css/common.css"
)
js = Bundle(
"libs/jQuery/dist/jquery.js",
"libs/bootstrap/dist/js/bootstrap.js",
"bower_components/moment/moment.js",
"bower_components/eonasdan-bootstrap-datetimepicker/build/js/bootstrap-datetimepicker.min.js",
"js/plugins.js",
filters='jsmin',
output="public/js/common.js"
)
assets = Environment()
assets.register("js_all", js)
assets.register("css_all", css)
myflaskapp/app.py initializes the assets:
from flask import Flask, render_template
from myflaskapp.assets import assets
"""
:param config_object: The configuration object to use.
"""
app = Flask(__name__)
app.config.from_object(config_object)
register_extensions(app)
register_blueprints(app)
register_errorhandlers(app)
return app
def register_extensions(app):
assets.init_app(app)
def register_blueprints(app):
app.register_blueprint(public.blueprint)
app.register_blueprint(user.blueprint)
In the myflaskapp/settings.py , during testing, I have set:
ASSETS_DEBUG = True # Don't bundle/minify static assets
Locally, there are no errors in the console. On heroku , I get an Internal server error. Logs:
←[33m2016-03-19T18:02:12.464159+00:00 app[web.1]:←[0m for org, cnt in self.resolve_contents(ctx):

As you can see in the top screenshot it is there. How can I fix this?
Note: I've been looking at https://github.com/mitsuhiko/flask/issues/348, which may have a bearing on this.
Try checking your .gitignore, build is often ignored which would exclude your static files here: bower_components/eonasdan-bootstrap-datetimepicker/build/*
这篇关于Flask-Assets在本地工作，但不在Heroku上的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
