    <p>I'm very new to Go so please forgive me if this is stupid obvious.</p> <p>I'm trying to post a form to a REST API written in Go using gorest. I've successfully done this using GET, but I can't get the POST data to parse into a map. Here is my Go code</p> <p>gotest.go:</p> <pre><code>package main import ( "code.google.com/p/gorest" "net/http" "fmt" ) func main() { gorest.RegisterService(new(HelloService)) //Register our service http.Handle("/",gorest.Handle()) http.ListenAndServe(":8787",nil) } //Service Definition type HelloService struct { gorest.RestService `root:"/api/"` save gorest.EndPoint `method:"POST" path:"/save/" output:"string" postdata:"map[string]string"` } func(serv HelloService) Save(PostData map[string]string) { fmt.Println(PostData) } </code></pre> <p>And my awesome html form:</p> <pre><code>&lt;form method="POST" action="http://127.0.0.1:8787/api/save/"&gt; key: &lt;input type="text" name="key" /&gt;&lt;br /&gt; json: &lt;input type="text" name="json" /&gt;&lt;br /&gt; &lt;input type="submit" /&gt; &lt;/form&gt; </code></pre> <p>I would think that would turn my post data into a nice map that I could access. I fill out the form, hit submit, and it returns an error:</p> <p><code>Error Unmarshalling data using application/json. Client sent incompetible data format in entity. (invalid character 'k' looking for beginning of value)</code></p> <p>EDIT: As greggory.hz points out, the program seems to think that the post data is a json. This error is because a json has to start with a brace, bracket or quote.</p> <p>If <code>map[string]string</code> with <code>string</code> it prints the following to the bash terminal where I am running this:</p> <p><code>key=arst&amp;json=%7B%27arst%27%3A%27arst%27%7D</code></p> <p>In the go rest documentation the only example of this that I could find is:</p> <pre><code>posted gorest.EndPoint method:"POST" path:"/post/" postdata:"User" func(serv HelloService) Posted(posted User) </code></pre> <p>But my attempts at creating a custom struct have also fails with the same unmarshalling error seen above.</p> <pre><code>type MyStruct struct { key,json string } </code></pre> <p>Can someone please tell me what data type I should be using? </p>

    1. COI'm mostly guessing here because I'm not familiar with gorest specifically, but I believe it's trying to parse the entirety of the POST data as JSON and not just the value associated with json key. That is, I believe it except ALL the data in the post request to be formatted as JSON.

    2. COMore specifically: key=arst&json=%7B%27arst%27%3A%27arst%27%7D is not valid JSON.

    3. COThe string `key=arst&json=%7B%27arst%27%3A%27arst%27%7D` looks like a URL variable path. Try unescaping the string (http://golang.org/pkg/net/url/#QueryUnescape). That error sounds like it's trying to unmarshall the word "key".

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
