# first we create an empty ActiveRecord::Relation object
relation = Model.where(attribute: value)

# then we make the relation stub the :[] method
# and return whatever values we need
relation.stub(:[]).and_return( Model.new({attrs: values})] )

# of course, we can make this too
# instead of the step above
record = double("Model", :foo => 'bar', :bar => 'baz')

Essential JavaScript Links

I no longer mantain this list. There are lots of other very comprehensive JavaScript link lists out there. Please see those, instead (Google "awesome JavaScript" for a start).

Rails naming conventions

General Ruby conventions

Class names are CamelCase.

Methods and variables are snake_case.

Methods with a ? suffix will return a boolean.

1. Install prettier
2. Make a .prettierignore file, and add directories you'd like prettier to not format, for example: **/node_modules
3. Run prettier --write "**/*.js" *Don't forget the quotes.
4. Optional: if you want to format JSON/SCSS files too, replace js with json/scss.
