    <p>I have a very simple ToDo List app made (following tutorial in comment below) using node.js, express and jade. The app works so I can add items to the list and it saves to the redis database with the id equal to the name of the list item. </p> <p>Now how can I edit my jade template so a delete button shows up beside the list item, and when I click it, then item will be deleted from the database? </p> <p>Here is the relevant code:</p> <p>Routes.js file</p> <pre><code>exports.index = function(req, res){ res.render('index', { title: 'Welcome to JSPlayground Todo' }); }; var redis = require("redis"), client = redis.createClient(); exports.todo = function(req, res){ //Pulls items from database to display on page var todos = []; client.hgetall("Todo", function(err, objs) { for(var k in objs) { var newTodo = { text: objs[k] }; todos.push(newTodo); } res.render('todo', { title: 'New Todo List', todos: todos }); }); }; exports.saveTodo = function(req, res) { //Saves a list item from input box to database var newTodo = {}; newTodo.name = req.body['todo-text']; newTodo.id = newTodo.name.replace(/ /g, ''); //console.log(newTodo.id); //console.log(newTodo.name); client.hset("Todo", newTodo.id, newTodo.name); res.redirect("back"); }; </code></pre> <p>todo.jade file</p> <pre><code>h1 new todo list form(action="/save", method="post") p label Enter a new todo item input(type='text',placeholder='new todo', name='todo-text') p input(type='submit', value='Save') ul each todo in todos li #{todo.text} </code></pre> <p>If I make a link on the template page </p> <pre><code>a(href="/del") del </code></pre> <p>and route /del to this function in the routes.js file</p> <pre><code>exports.delTodo = function(req, res) { var delTodo = {}; delTodo.id = "Test"; client.hdel("Todo", delTodo.id); res.redirect("back"); }; </code></pre> <p>It will delete a single list item with id of "Test". But I am not sure how to get it to delete the specific list item that was clicked. </p>

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.
