我正在尝试在Django应用程序中使用Python Social Auth注销,但我得到了

NotAllowedToDisconnect at /disconnect/facebook/1/

这些是我的设置:

SOCIAL_AUTH_PIPELINE = (
    'social.pipeline.social_auth.social_details',
    'social.pipeline.social_auth.social_uid',
    'social.pipeline.social_auth.auth_allowed',
    'social.pipeline.social_auth.social_user',
    'social.pipeline.user.get_username',
    'social.pipeline.mail.mail_validation',
    'social.pipeline.user.create_user',
    'social.pipeline.social_auth.associate_user',
    'social.pipeline.social_auth.load_extra_data',
    'social.pipeline.user.user_details'
)



SOCIAL_AUTH_DISCONNECT_PIPELINE = (
    'social.pipeline.disconnect.allowed_to_disconnect',
    'social.pipeline.disconnect.get_entries',
    'social.pipeline.disconnect.revoke_tokens',
    'social.pipeline.disconnect.disconnect'
)

这是我在模板上使用的代码

{{ assoc.provider }} (<a href="{% url 'social:disconnect_individual' assoc.provider assoc.id %}" class="disconnect">Disconnect </a>)

我正在尝试将UTC的时区更改为America/Sao Paulo,但我收到此错误:

TypeError: replace() takes no keyword arguments

这是我的代码:

import pytz

local_tz = pytz.timezone('America/Sao_Paulo')
local_dt = candles[0]['time'].replace(tzinfo=pytz.utc).astimezone(local_tz)

蜡烛时间是:

>>> candles[0]['time']
u'2017-08-03T00:03:00.000000Z'

我怎样才能解决这个问题？

我正在尝试使用我的 Laravel 应用程序创建一个 api，但是当我对路由发出 post 请求时，Laravel 默认情况下会尝试验证 csrf 令牌。所以，我想删除 api 路由的这个验证。我想维护前端请求的验证。但是当我在 app/Http/Middleware/VerifyCsrfToken.php 中添加异常路由时，我收到了这个错误：

block_exception clear_fix

这是VerifyCsrfToken.php

<?php

namespace App\Http\Middleware;

use Illuminate\Foundation\Http\Middleware\VerifyCsrfToken as BaseVerifier;

class VerifyCsrfToken extends BaseVerifier
{
    /**
     * The URIs that should be excluded from CSRF verification.
     *
     * @var array
     */
    protected $except = [
        //
        'log_bounces_complaints',
    ];
}

我正试图在Mac Os高山上运行

pip install MySQL-python

但我得到了

error: command 'cc' failed with exit status 1

我已经尝试过关于这个主题的解决方案,但它没有用.

这是完整的错误消息

我正在尝试在两个模型之间引用外键.

但我收到这个错误:

throw new Error(this.name + '.' + Utils.lowercaseFirst(Type.toString()) + ' called with something that\'s not an instance of Sequelize.Model');
called with something that's not an instance of Sequelize.Model
    at Model.belongsTo

我怎样才能解决这个问题？

到目前为止这是我的代码.

这是我的模特/ mercadolibre.js

"use strict";
var User  = require('../models/index').User;

module.exports = function(sequelize, DataTypes) {
  var MercadoLibre = sequelize.define("MercadoLibre", {
    id:  { 
          type: DataTypes.INTEGER, 
          autoIncrement: true, 
          primaryKey: true
        },
    access_token: DataTypes.STRING,
    refresh_token: DataTypes.STRING,
    environment_hash: DataTypes.STRING 
  }, {
    tableName: 'mercadolibres',
    underscored: true,
    timestamps: true
  }

  );

  MercadoLibre.belongsTo(User);

  return MercadoLibre;
}; …

我正试着跑:

pip install boto3

但是我收到了这个错误:

我正在尝试使用此包pywebpush,但我收到此错误:

我正在尝试处理 XML 文件，但出现此错误：

XPathEvalError: Undefined namespace prefix

在这一行：

print "category =", item.xpath("./g:google_product_category")

这是 XML 文件：

<channel>
<title>example.net.br</title>
<link>http://www.example.net.br/</link>

这是我的代码：

req = urllib2.Request(feed_url, None, headers)
file = urllib2.urlopen(req).read()

file = etree.fromstring(file)

我在osX上尝试这个:

我正试图通过以下公式从Google表格中获取Google财经数据:

=GoogleFinance("CURRENCY:BTC")

但是我收到了这个错误:

GOOGLEFINANCE, the query for the symbol: 'CURRENCY:BTC' returned no data.

虽然在Google财经上,我可以获得BTC价格:

https://www.google.com/finance?q=CURRENCY:BTC

使用相同的查询字符串.

我怎么能解决这个问题？
