7 RESTful routes and use PUT in HTML form

2018-01-09

7 RESTful routes

CRUD stands for Create, Read, Update and Destroy. REST is a mapping between HTTP routes and CRUD.

name url verb desc Mongoose method
INDEX /dogs GET Display a list of all dogs Dog.find()
NEW /dogs/new GET Display form to make a new dog N/A
CREATE /dogs POST Add new dog to DB Dog.create()
SHOW /dogs/:id GET Show info of a dog, should be after NEW Dog.findById()
EDIT /dogs/:id/edit GET Show edit form for one dog Dog.findById()
UPDATE /dogs/:id PUT Update a particular dog, then redirect Dog.findByIdAndUpdate()
Destroy /dogs/:id DELETE Delete a particular dog, then redirect Dog.findByIdAndRemove()

PUT in HTML form

HTML <form> cannot send a request other than GET and POST, like PUT.

In order to solve this in Node, first install method-override package. Then use form header as:

<form action="/blogs/<%= blog._id %>?_method=PUT" method="POST">

</form>
var methodOverride = require("method-override");
app.use(methodOverride("_method"));

app.put("/blogs/:id", function(req, res) {
    Blog.findByIdAndUpdate(req.params.id, req.body.blog, function(err, updatedBlog) {
        // if err
    });
});
