uAdmin Tutorial Part 13 - Accessing an HTML file

In this part, we will talk about establishing a connection to the Page Handler, setting the URL path name, and executing an HTML file.

Go to view.go inside the views folder with the following codes below:

package views

import (
    "net/http"
    "strings"
)

// PageHandler !
func PageHandler(w http.ResponseWriter, r *http.Request) {
    // r.URL.Path creates a new path called "/page/"
    r.URL.Path = strings.TrimPrefix(r.URL.Path, "/page")
    r.URL.Path = strings.TrimSuffix(r.URL.Path, "/")
}

Establish a connection in the main.go to the views by using http.HandleFunc. It should be placed after the uadmin.Register and before the StartServer.

import (
    "net/http"

    // Specify the username that you used inside github.com folder
    "github.com/username/todo/api"
    "github.com/username/todo/models"

    // Import this library
    "github.com/username/todo/views"

    "github.com/uadmin/uadmin"
)

func main() {
    // Some codes

    // HTTP UI Handler
    http.HandleFunc("/page/", uadmin.Handler(views.PageHandler))
}

Create a file named todo_view.go inside the views folder with the following codes below:

package views

import (
    "net/http"

    "github.com/uadmin/uadmin"
)

// TodoList field inside the Context that will be used in Golang HTML template
type Context struct {
    TodoList []map[string]interface{}
}

// TodoHandler !
func TodoHandler(w http.ResponseWriter, r *http.Request) {
    // Assigns Context struct to the c variable
    c := Context{}

    // Pass TodoList data object to the specified HTML path
    uadmin.RenderHTML(w, r, "templates/todo.html", c)
}

Finally, add this piece of code in the view.go shown below. This will establish a communication between the PageHandler and the TodoHandler.

// PageHandler !
func PageHandler(w http.ResponseWriter, r *http.Request) {
    // r.URL.Path creates a new path called "/page/"
    r.URL.Path = strings.TrimPrefix(r.URL.Path, "/page")
    r.URL.Path = strings.TrimSuffix(r.URL.Path, "/")

    if strings.HasPrefix(r.URL.Path, "/todo") {
        TodoHandler(w, r)
        return
    }
}

Now run your application, go to http://localhost:8080/page/todo path and see what happens.

In the next part, we will discuss about fetching the records in the API and migrating the data from API to HTML that will display the records using Go template.
