How to fix Cannot PUT /blogs/:id

Question

I am making RESTful BlogApp and PUT method is not working.I only get error saying Cannot PUT /blogs/:id. I don't see what could go wrong. Everything looks fine to me. Please let me know if you find a problem. I know this might be a bad post but it is one of my first posts. Here is what i coded:

<form action="/blogs/<%= blog._id %>?_method=PUT" method="POST" class="ui 
form">
            <div class="field">
                <label for="blog[tittle]">Tittle</label>
                <input name="blog[tittle]" type="text" value="<%= 
blog.tittle %>">
            </div>
            <div class="field">
                <label for="blog[image]">Image URL</label>
                <input name="blog[image]" type="text" value="<%= blog.image 
%>">
            </div>
            <div class="field">
                <label for="blog[body]">Content</label>
                <textarea name="blog[body]"><%= blog.body %></textarea>
            </div>
        <button type="submit" class="ui blue button">Save</button>
    </form>
