Locate the section for your github remote in the .git/config
file. It looks like this:
[remote "origin"]
fetch = +refs/heads/*:refs/remotes/origin/*
url = [email protected]:joyent/node.git
Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/*
to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:
Go to Sublime Text 2 > Preferences > Key Bindings - User
and add this JSON to the file:
[
{ "keys": ["super+shift+l"],
"command": "insert_snippet",
"args": {
"contents": "console.log(${1:}$SELECTION);${0}"
}
}
The normal controller/view flow is to display a view template corresponding to the current controller action, but sometimes we want to change that. We use render
in a controller when we want to respond within the current request, and redirect_to
when we want to spawn a new request.
The render
method is very overloaded in Rails. Most developers encounter it within the view template, using render :partial => 'form'
or render @post.comments
, but here we'll focus on usage within the controller.
