Depreciation of Handlebar syntax - Blog and code.

[f0ru0l0rd]

After starting ember serve today, I recieved several of the following messages. This happened as I was working through your example.

DEPRECATION: Using the '{{#each item in model}}' form of the {{#each}} helper (' todo-mvc/templates/todos.hbs' @ L5:C8) is deprecated. Please use the block param form instead ('{{#each model as |item|}}'). See http://emberjs.com/guides/depre cations/#toc_code-in-code-syntax-for-code-each-code for more details. at D:\Sites\todo-mvc\bower_components\ember\ember-template-compiler.js:1 1916:36 at Walker.visit (D:\Sites\todo-mvc\bower_components\ember\ember-template -compiler.js:18280:7) at visitors.ElementNode (D:\Sites\todo-mvc\bower_components\ember\ember- template-compiler.js:18296:16) at Walker.children (D:\Sites\todo-mvc\bower_components\ember\ember-templ ate-compiler.js:18313:7) at Walker.visit (D:\Sites\todo-mvc\bower_components\ember\ember-template -compiler.js:18281:12) at visitors.ElementNode (D:\Sites\todo-mvc\bower_components\ember\ember- template-compiler.js:18296:16) at Walker.children (D:\Sites\todo-mvc\bower_components\ember\ember-templ ate-compiler.js:18313:7) at Walker.visit (D:\Sites\todo-mvc\bower_components\ember\ember-template -compiler.js:18281:12) at visitors.Program (D:\Sites\todo-mvc\bower_components\ember\ember-temp late-compiler.js:18290:16) DEPRECATION: Using '{{input action="createTodo"}}' ('todo-mvc/templates/todos.hb s' @ L1:C0) is deprecated.

It appears that there are several places where the handlebars syntax being used was depreciated. Replacing the former with the new coede caused it to no longer throw errors, but would not iterate over the todos, thus they are all blank.

If it were not for the fact that I eat promises for breakfast, I'd propose a solution to this, but the fact is, I no longer have a solution, and unfortunately one more code example that doesn't work.

Thanks. I'm re-writing the tutorial for ember 2.0. Watch this space.

I was going through your tutorial but I despite following all your instructions, I was never able to get the line-through to work for me and once I implemented the code in your child routes section I had all my content disappear. Are these problems that will be resolved with the Ember 2.0 tutorial?

The 2.0 tutorial should work. If it does not, email me with the problems and I'll take a look.

Thanks,
