A. I’m reading
JQuery Fundamentals: after realizing that I don’t know the syntax of jquery well enough, I decided to self-educate myself on that matter. And I made a decision to start by reading a book, to at least have the basic knowledge.
B. Something new
Using the localization in jquery-ui-datepicker
//= require datepicker-it
when written in a *.js file, that line is first parsed by Sprocket in Rails. This line tells rails to preload some external javascript files.
And in order to use a datepicker, we need to include all the languages that we’re going to use.
New gems
spreewald: from makandra, predefine most frequently used cucumber steps.
consul: from makandra again, to restrict the access right to data.
&&
vs. and
in ruby
use &&
for the task when you need only the boolean output. &&
has high precedence.
The and
usage is more complicated, in a sense that it connects two parts of the evaluation. Use and
in control flow. and
has low precedence.
False value
Ruby: false, nil
Javascript: false, NaN, 0, empty string, undefined. In short, this article says, only object is truthy.
C. Something to remember
- To deploy the code,
vagrant ssh
, and thenbundle exec cap playground deploy
. Since we need the ssh private key, and we can only have access to that key while we are still inside the local environment. Deploying from the terminal in vagrant would not work.
My mistakes
