* 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.

|/ | | | | | | | | | | Before, an error would be raised saying that the method `to_param` was undefined on the instance of `ActionController::Parameters`. Now, we are checking to see if the `params` object being passed to `button_to` responds to the `permitted?` method, and if so, we will call `to_h` on it. If it does not respond to `permitted?`, then the `params` will remain unchanged. [Jon Moss, Rafael Mendonça França]

* Fix button_to's params option to support nested names.James Coleman2016-02-191-2/+38
| | | | | | In e6e0579defcfcf94ef1c4c1c7659f374a5335cdb the `params` option was added to the `button_to` helper. However, the patch doesn't support nested hashes so `{a: {b: 'c'}}` for example gets turned into a hidden form input with the name 'a' and the value being the string representation of the `{b: 'c'}` nested hash. Since Rails supports nested hashes everywhere else (and even in the URL params of link_to and button_to), I believe this to be a bug/unfinished feature.

| | | | | | Due to e25fdad2f147e6f368958f9a06a5ac9d10288408, we are correctly using path escaping for email addresses. This commit fixes the tests to expect path escaping.
* Cut string allocations in content_tag_stringschneems2015-07-291-2/+2
| | | | | | content_tag's first argument is will generate a string with an html tag so `:a` will generate: `<a></a>`. When this happens, the symbol is implicitly `to_s`-d so a new string is allocated. We can get around that by using a frozen string instead which This change buys us 74,236 bytes of memory and 1,855 fewer objects per request.

* Remove additional handling of boolean attributes on button to helperCarlos Antonio da Silva2015-03-181-30/+0
| | | | | | | | This logic was just doing duplicated work, since the button_to helper relies on tag/content_tag to generate the button html, which already handles all boolean attributes it knows about. The code dates back to 2005: 43c470fae468ef63e0d5c3dc1e202925685fd47b.

* | Indicate link_to creates an anchor elementColin Rymer2015-02-061-2/+2
| | | | | | | | | | | | The `link_to` helper generates an HTML anchor element (consisting of opening and closing anchor tags and an element body). The docs currently state the a link tag is generated (which would indicate a tag like `<link>`, which is another valid HTML tag), so this change clarifies that an anchor element is actually generated.

| | | | | | | | | | [ci skip] 89ff1f8 and 1de258e6 removed from the HTML generated by the form helpers the <div> that was wrapping the field elements inside the <form>. This commit updates the documentation of the methods to reflect the two commits above.
* In actionview, eliminate calls to tag that use html_safe parameter values. ↵Paul Grayson2014-06-131-5/+3
