Implementing the Route handlers

The showArticleCreationPage handler is similar to the the previously created handlers that display static pages.

The createArticle is similar to the register handler created in a previous section.

The updated handlers.article.go file should contain the following code:

// handlers.article.go

func showArticleCreationPage(c *gin.Context) {
    render(c, gin.H{
        "title": "Create New Article"}, "create-article.html")
}

func createArticle(c *gin.Context) {
    title := c.PostForm("title")
    content := c.PostForm("content")

    if a, err := createNewArticle(title, content); err == nil {
        render(c, gin.H{
            "title":   "Submission Successful",
            "payload": a}, "submission-successful.html")
    } else {
        c.AbortWithStatus(http.StatusBadRequest)
    }
}

After implementing these handlers, the tests should execute successfully and show the following result:

Now that we've implemented quite a bit of functionality in the application, let's add some authorization checks to some of the functionality.
