blaze-tutorial's Issues

Cannot read property 'helpers' of undefined

I have followed step1 of the simple-todo tutorials. I am getting the above error.
My meteor version is 2.2

Tutorial - missing important instruction at https://blaze-tutorial.meteor.com/simple-todos/04-update-and-remove.html#4-1-Add-Checkbox

https://blaze-tutorial.meteor.com/simple-todos/04-update-and-remove.html#4-1-Add-Checkbox is missing an important detail.
While it mentions adding a new file task.html to describe template 'task', it forgets to mention that this template is already existing in App.html, which should be removed. In absence of this instruction, the page just displays task addition part and not the existing task list. This may be very confusing to the student.

Please reflect the instruction in https://blaze-tutorial.meteor.com/simple-todos/04-update-and-remove.html#4-1-Add-Checkbox .

Wrong file location at https://blaze-tutorial.meteor.com/simple-todos/07-adding-user-accounts.html#7-7-Task-owner

Here, at the end the code to insert asks to update import/ui/Task.js 's form submit event handler
The tutorial had hitherto placed the form submit event handler used to reside at import/ui/App.js
We should correct the creation place of form event handler from import/ui/App.js to import/ui/Task.js

Missing instruction in https://blaze-tutorial.meteor.com/simple-todos/08-methods.html#8-4-api-and-db-folders

In the list of files that need to be modified after moving TasksCollection.js to db directory, the tutorial states 3 files need modification.
However, it misses that imports/api/tasksMethods.js needs be modified too.
Without this step, the application crashes spectacularly.

... unless there is a need to merge this file with TasksCollection.js before moving the latter to db. In that case, that instruction is missing and also instructions to remove references to import of tasksMethods.js

Hide Completed/Show All has a bug and its fix

Hide Completed/Show All as shown in tutorial has a bug.

1. Check a task
2. Press "Hide Completed"
3. The task doesn't show
4. Press "Show all"
5. The task shows up
6. Bad, current behavior: The task checkbox is displayed unchecked, leading the user to think the task is not checked - and mismatches unchecked tasks with the pending count (by one, in this case)
7. Correct, future behavior: The task checkbox is checked

The fix lies in imports/ui/Task.html
Instead of:
<input type="checkbox" class="toggle-checked" />
or similar code,
Mention:
{{#if isChecked}} <input type="checkbox" checked class="toggle-checked"/> {{else}} <input type="checkbox" class="toggle-checked" /> {{/if}}

https://blaze-tutorial.meteor.com/simple-todos/02-collections.html - important detail missing

I am not sure whether tutorial related issues should be reported here.
In https://blaze-tutorial.meteor.com/simple-todos/02-collections.html#2-3-Render-Tasks-Collection , restarting Meteor is necessary for the changes to reflect. Otherwise the student gets a blank screen - the former static data is gone and MongoDB doesn't load.

Please mention "Restart Meteor" as a required step.

Errors

There are a couple of errors which would be confusing for novice users.
1.2 refers to 'Meteor with React' this tutorial is for Blaze not React.
1.4 Line 5 'Template.app.helpers' there is no template named 'app' so this will cause an error it should be 'Template.maincontainer.helpers'
