Here's an example of how you can add a route and a UI component to add a patient:
Add a route to add a patient
In your routes.clj
file, add the following route:
(defroutes patient-routes
(POST "/patients" request (add-patient-handler request)))
(defn add-patient-handler [request]
(let [params (:params request)
name (:name params)
sex (:sex params)
date-of-birth (:date-of-birth params)
address (:address params)
social-security-number (:social-security-number params)]
(try
(add-patient name sex date-of-birth address social-security-number)
(response "Patient added successfully!")
(catch Exception e
(response (str "Error adding patient: " (.getMessage e)) 500)))))
This route listens for a POST request to /patients
and calls the add-patient-handler
function. The handler extracts the parameters from the request, calls the add-patient
function, and returns a response indicating whether the patient was added successfully or not.
Add a UI component to add a patient
Create a new file add_patient.html
in your resources/public
directory:
<!DOCTYPE html>
<html>
<head>
<title>Add Patient</title>
</head>
<body>
<h1>Add Patient</h1>
<form action="/patients" method="post">
<label for="name">Name:</label>
<input type="text" id="name" name="name"><br><br>
<label for="sex">Sex:</label>
<input type="text" id="sex" name="sex"><br><br>
<label for="date-of-birth">Date of Birth:</label>
<input type="date" id="date-of-birth" name="date-of-birth"><br><br>
<label for="address">Address:</label>
<input type="text" id="address" name="address"><br><br>
<label for="social-security-number">Social Security Number:</label>
<input type="text" id="social-security-number" name="social-security-number"><br><br>
<input type="submit" value="Add Patient">
</form>
</body>
</html>
This is a simple HTML form that allows the user to input the patient's details. When the form is submitted, it sends a POST request to /patients
with the input data.
Update your handler.clj
file
Add a route to serve the add_patient.html
file:
(defroutes app-routes
...
(GET "/add-patient" [] (resource-response "add_patient.html" {:root "public"}))
...)
This route serves the add_patient.html
file when the user navigates to /add-patient
.
That's it! Now you should be able to add a patient by navigating to /add-patient
in your browser, filling out the form, and submitting it.
To add a UI component to get all patients, you'll need to create a web interface that interacts with your CRUD API. One way to do this is by using a ClojureScript library like Reagent or Rum, which allow you to create reactive UI components.
Here's an example of how you could create a simple UI component using Reagent to display all patients:
First, add the necessary dependencies to your project.clj
file:
(defproject hs-clojure "0.1.0-SNAPSHOT"
...
:dependencies [[org.clojure/clojure "1.10.0"]
[org.clojure/clojurescript "1.10.520"]
[reagent "0.8.1"]
...])
Create a new namespace for your UI component:
; src/cljs/hs_clojure/ui.cljs
(ns hs-clojure.ui
(:require [reagent.core :as r]
[cljs-http.client :as http]
[cljs.core.async :refer [<! >!]])
(:import [goog Uri]))
(defonce patients (r/atom []))
(defn get-all-patients []
(http/get "/api/patients"
{:handler (fn [response]
(reset! patients response))}))
(defn patient-list []
[:ul
(for [patient @patients]
^{:key patient} [:li (:name patient)])])
(defn main-panel []
[:div
[:h1 "Patients"]
[patient-list]
[:button {:on-click get-all-patients} "Get All Patients"]])
(defn ^:export main []
(r/render [main-panel]
(.getElementById js/document "app")))
Create an HTML file to render the UI component:
<!-- resources/public/index.html -->
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>HS Clojure</title>
</head>
<body>
<div id="app"></div>
<script src="js/main.js"></script>
</body>
</html>
Update your handler.clj
file to include the API endpoint for getting all patients:
; src/hs_clojure/handler.clj
(ns hs-clojure.handler
...
(:require [hs-clojure.patients :as patients]))
(defroutes app-routes
...
(GET "/api/patients" [] (patients/get-all-patients))
...)
Start your ClojureScript compiler and web server:
lein cljsbuild once
lein ring server
Open your web browser and navigate to http://localhost:3000
. You should see a simple UI component that displays a list of patients when you click the "Get All Patients" button.
Note that this is just a basic example to get you started. You'll likely want to add more features, error handling, and styling to your UI component.
To add a Reagent UI to your project, you'll need to create a new namespace for your UI components and use Reagent's atom
and render
functions to create a reactive UI.
Here's a step-by-step guide to get you started:
1. Add Reagent to your project
In your project.clj
file, add the following dependency:
[reagent "0.10.0"]
2. Create a new namespace for your UI components
Create a new file src/hs_clojure/ui.cljs
with the following content:
(ns hs-clojure.ui
(:require [reagent.core :as r]
[reagent.dom :as rd]))
3. Create a UI component
In the hs_clojure.ui
namespace, create a simple UI component, such as a patient list:
(defn patient-list []
(let [patients (r/atom [])]
(fn []
[:div
[:h1 "Patients"]
[:ul
(for [patient @patients]
[:li (:name patient)])]
[:button {:on-click #(fetch-patients!)} "Fetch patients"]]))
(defn fetch-patients! []
(GET "/api/patients" {:handler (fn [response]
(reset! patients response))}))
This component uses an atom patients
to store the patient data and a fetch-patients!
function to retrieve the data from your API.
4. Create a Reagent app
Create a new file src/hs_clojure/app.cljs
with the following content:
(ns hs-clojure.app
(:require [hs-clojure.ui :as ui]
[reagent.core :as r]))
(defn app []
[ui/patient-list])
(r/render [app] (.getElementById js/document "app"))
This file defines a Reagent app that renders the patient-list
component.
5. Update your HTML file
Create a new file resources/public/index.html
with the following content:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>HS Clojure</title>
</head>
<body>
<div id="app"></div>
<script src="js/compiled/app.js"></script>
</body>
</html>
This file sets up an HTML page with a div
element that will be used to render the Reagent app.
6. Compile your ClojureScript code
Add the following configuration to your project.clj
file:
:cljsbuild
{:builds
{:app {:source-paths ["src/hs_clojure"]
:compiler {:output-to "resources/public/js/compiled/app.js"
:optimizations :advanced
:pretty-print false}}}}
This configuration tells ClojureScript to compile your app.cljs
file and output the compiled JavaScript code to resources/public/js/compiled/app.js
.
7. Run your application
Run lein cljsbuild once
to compile your ClojureScript code. Then, start your Ring server with lein ring server
. Open your web browser and navigate to http://localhost:3000
to see your Reagent UI in action!
This is just a basic example to get you started. You'll need to modify the UI components and API endpoints to fit your specific requirements. requires #9
Clojure/ClojureScript
To check if your form works, you can follow these steps:
1. Start your Clojure API: Run your Clojure API using
lein run
orjava -jar your-jar-file.jar
(depending on how you're running your API).2. Open your web page: Open a web browser and navigate to
http://localhost:3000
(or the URL where your API is running). You should see your HTML form.3. Fill out the form: Fill out the form with some sample data, such as:
4. Submit the form: Click the "Add Patient" button to submit the form.
5. Check the API response: Check the API response in the browser's developer tools (e.g., Chrome DevTools) or using a tool like Postman.
6. Verify the patient was added: Check your database or API logs to verify that the patient was successfully added.
7. Test error scenarios: Test error scenarios, such as:
By following these steps, you can verify that your form is working correctly and your API is processing the form data as expected.
