Question

我正在构建一个使用zappa部署到AWS Lambda的烧瓶应用程序，并且我尝试使用Flask-s3来处理静态文件。我之前从未使用过[Flask-S3] [1]它看起来相当简单，但我得到......

AttributeError: 'FlaskS3' object has no attribute 'url_for'

他们我理解你只需要用url_for替换你的静态网址就像这样：

app.config['FLASKS3_BUCKET_NAME'] = 'mybucketname'
s3 = FlaskS3(app)

s3.url_for('static/file.jpg')

这不是很清楚，我做错了什么，但几乎没有任何在线故障排除Flask-s3。一切都有帮助。

app = Flask(__name__)
Bootstrap(app)
app.config['FLASKS3_BUCKET_NAME'] = 'mybucketname'
s3 = FlaskS3(app)
MAILGUN_API_KEY = 'key'
auth = ('api', MAILGUN_API_KEY)


@app.route("/", methods=['GET', 'POST'])
def index():
    context = {
    'image': url_for('static/property_home.jpeg'),
    'heading': 'We sell property - At a discount!',
    'landing_video': url_for('static/intro.mp4')
    }
    form = forms.OptIn()
    if form.validate_on_submit():
        validate = requests.get(
            "https://api.mailgun.net/v3/address/private/validate",
            auth=auth,
            params={"address": form.email.data})
        if validate.json()['did_you_mean'] is not None:
            flash('Did you mean {}?'.format(validate.json()['did_you_mean']))
        elif validate.json()['is_valid'] == True and validate.json()['is_role_address'] == False and validate.json()['is_disposable_address'] == False:
            r = requests.post(
            "https://api.mailgun.net/v3/lists/YOUR_DOMAIN_NAME/members",
            auth=auth,
            data={'subscribed': True,
                  'address': form.email.data})
            if r.status_code == 200:
                requests.post('https://api.mailgun.net/v3/YOUR_DOMAIN_NAME/messages',
                    auth=auth,
                    data={"from": 'Matt@SpokaneDiscountProperties.com',
                        "to": form.email.data,
                        "subject": "Welcome to Spokane Discount Properties",
                        "html": open('templates/indoc.html'),
                        "o:tag": 'indoctrinated'})
                flash('Thanks, we will notify you when we have more properties')
            else:
                flash('You are already subscribed, we will notify you when more properties are available')
        else:
            flash('Holy guacamole! Best check yo self, this is not a valid email.')
    return render_template('index.html', form=form, context=context)

使您的应用程序使用外部Amazon S3 URL 在提到你的应用程序的静态资产时，通过你的Flask 只需要完成FlaskS3对象的对象。

该扩展程序负责为您处理url_for。所以你可能不需要直接调用它。

在内部，每次在您的某个应用程序中调用url_for 模板，而是调用flask_s3.url_for。如果是端点提供被认为是指静态资产，然后是S3的URL 而是返回filename参数中指定的资产。否则，flask_s3.url_for将调用传递给flask.url_for。

改变这个：

context = {
    'image': url_for('static/property_home.jpeg'),
    'heading': 'We sell property - At a discount!',
    'landing_video': url_for('static/intro.mp4')
    }

为：

context = {
    'image': url_for('static', filename= 'property_home.jpeg'),
    'heading': 'We sell property - At a discount!',
    'landing_video': url_for('static', filename='intro.mp4')
    }

AttributeError：＆＃39; FlaskS3＆＃39;对象没有属性＆＃39; url_for＆＃39;
