* Enable autocorrect for `Lint/EndAlignment` copKoichi ITO2018-01-181-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ### Summary This PR changes .rubocop.yml. Regarding the code using `if ... else ... end`, I think the coding style that Rails expects is as follows. ```ruby var = if cond a else b end ``` However, the current .rubocop.yml setting does not offense for the following code. ```ruby var = if cond a else b end ``` I think that the above code expects offense to be warned. Moreover, the layout by autocorrect is unnatural. ```ruby var = if cond a else b end ``` This PR adds a setting to .rubocop.yml to make an offense warning and autocorrect as expected by the coding style. And this change also fixes `case ... when ... end` together. Also this PR itself is an example that arranges the layout using `rubocop -a`. ### Other Information Autocorrect of `Lint/EndAlignment` cop is `false` by default. https://github.com/bbatsov/rubocop/blob/v0.51.0/config/default.yml#L1443 This PR changes this value to `true`. Also this PR has changed it together as it is necessary to enable `Layout/ElseAlignment` cop to make this behavior.

| | | | | | | | | | When `form_with` was introduced we disabled the automatic generation of ids that was enabled in `form_for`. This usually is not an good idea since labels don't work when the input doesn't have an id and it made harder to test with Capybara. You can still disable the automatic generation of ids setting `config.action_view.form_with_generates_ids` to `false.`

* | Prevent extra string allocations when no 'rel' arg passedDillon Welch2017-10-261-3/+7
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Do a check if the 'rel' argument is passed in, and simply set it to 'nofollow' if 'rel' was not passed in. This prevents three string allocations for each call to `link_to` in that scenario. In the scenario where the 'rel' argument is passed in, performance is around the same as before as the `key?` check is very fast. ```ruby begin require "bundler/inline" rescue LoadError => e $stderr.puts "Bundler version 1.10 or later is required.
