问题标签 [dreamfactory]

在 Dream Factory 中，我创建了一个服务，通过它我可以连接到远程 postgreSQL 并能够从那里进行 crud 操作，我还生成了 API。现在我有两个问题：

1. 该 API 将如何连接到我创建的服务？
2. 如何在我的 android 应用程序中使用生成的 API？

In teh .NET SDK your create record method passes a 0 for id on all records as this is unknown until teh response comes back with the id's populated etc

It Seems that the JSON DefaultValueHandling = DefaultValueHandling.Ignore is not working on the freshly minted int '0' id's

An therefore the body has the id:0 and trys inserts the records with id:0 on all and trips a Unique constraint on the inner exception in fiddler

我正在使用梦工厂 2 为 mysql 数据库创建一个 api。目前我有几张桌子，但我将以三个为例。表 1 A 列 B 列 表 2 A 列 B 列 表 3 A 列 B 列

表 1 可以通过关系键访问表 2，因此表 1 列 A = 表 2 列 B。表 2 也可以通过关系键访问表 3，因此表 2 列 A = 表 3 列 B。我的问题是在梦工厂谁我会从表 1 访问表 3。

通常，如果我进入 api 文档并请求相关数据，我可以提取与该表关联的任何相关数据，但在这种情况下，表 3 与表 1 没有直接关联。我知道一个选项是存储过程，但存在这可以用 Dreamfactory 完成而不使用任何存储过程吗？

我正在尝试在 Ionic 应用程序中实现 Dreamfactory OAuth。我正在关注此资源以进行实施： http ://wiki.dreamfactory.com/DreamFactory/Tutorials/Using_OAuth

这是我正在打的电话：

上面的日志显示了 json 数据，因为它本身重定向到调用返回的 facebook url，它只返回该 facebook 页面的 HTML。

我应该在混合/离子应用程序中使用不同的方法进行 DF OAuth 登录吗？

尝试在 Ionic 应用程序中实现 Facebook OAuth 时出现错误。

这就是我的 POST 请求 url 的样子：

https://df-apiurl.com/api/v2/user/session?oauth_callback=true&service=facebook&code=**********&state=********

这是错误响应。相关部分可能是：

"message":"客户端错误：POST https://graph.facebook.com/oauth/access_token导致400 Bad Request响应：\n{"error":{"message":"验证验证码出错。请确保您的 redirect_uri 与您的相同（截断...）\n"

但这里是完整的错误信息，以防万一。

DreamFactory 安装程序（通过 php artisan）提示“输入您的数据库名称：”，不确定数据库是什么意思，它要我设置一个全新的数据库名称还是现有数据库的名称？

我正在开发一个电子商务 android 应用程序。我正在尝试基于多个过滤器使用适用于 android 的 dreamfactory API 获取记录。

使用名为 GetProductsBySubCatIdTask 的 AsyncTask

我使用了在类外部构造并作为参数提供的过滤器，可能的过滤器是

以上所有过滤器都可以单独使用，也可以组合使用 2 个或 3 个，例如

转义字符串中的符号后，如

无法获得所需的结果，在文档中搜索但没有找到确切的内容。

什么是可能的解决方案？

如何在 DreamFactory 上使用 multipart 上传图像？

我正在使用 angualr2，尝试过 xhr 和 http.post。两者都不起作用我得到 201 状态代码并返回空资源。文件只是说

没有明确的解释

是否能够实现从两个表中获取结构化响应的过程功能

我有两个表：“公司”和“电话”

Company 包含公司，Phone 包含每个公司的电话号码。一家公司 --> 多部由 companyID 关联的电话

我需要这个结构：

问题是它们在单独的表中，我不知道如何实现它。

我使用dreamfactory作为后端

此代码应该采用 ISBN 或书名，并针对 googles book API 运行它，返回有效结果。该代码似乎可以自行运行，但是当我们将其放入 Dreamfactory 服务器时，它返回它无法设置未定义的属性“_renderItem”。
