* Don't expect defined protect_against_forgery? in {token,csrf_meta}_tagGenadi Samokovarov2018-12-271-1/+1
| | | | | | | | | | | | | | | | | | | The `#csrf_meta_tags` and `#token_tag` Action View helper methods are expecting the class in which are included to explicitly define the method `#protect_against_forgery?` or else they will fail with `NoMethodError`. This is a problem if you want to use Action View outside of Rails applications. For example, in #34788 I used the `#button_to` helper inside of the error pages templates that have a custom `ActionView::Base` subclass, which did not defined `#protect_against_forgery?` and trying to call the button failed. I had to dig inside of Action View to find-out what's was going on. I think we should either set a default method implementation in the helpers or check for the method definition, but don't explicitly require the presence of `#protect_against_forgery?` in every `ActionViews::Base` subclass as the errors are hard to figure out.
* Add `Style/RedundantFreeze` to remove redudant `.freeze`Yasuo Honda2018-09-291-11/+11
| | | | | | | | | | | | | | | | | | | | | Since Rails 6.0 will support Ruby 2.4.1 or higher `# frozen_string_literal: true` magic comment is enough to make string object frozen. This magic comment is enabled by `Style/FrozenStringLiteralComment` cop. * Exclude these files not to auto correct false positive `Regexp#freeze` - 'actionpack/lib/action_dispatch/journey/router/utils.rb' - 'activerecord/lib/active_record/connection_adapters/sqlite3_adapter.rb' It has been fixed by https://github.com/rubocop-hq/rubocop/pull/6333 Once the newer version of RuboCop released and available at Code Climate these exclude entries should be removed. * Replace `String#freeze` with `String#-@` manually if explicit frozen string objects are required - 'actionpack/test/controller/test_case_test.rb' - 'activemodel/test/cases/type/string_test.rb' - 'activesupport/lib/active_support/core_ext/string/strip.rb' - 'activesupport/test/core_ext/string_ext_test.rb' - 'railties/test/generators/actions_test.rb'
* Fix issue with `button_to`'s `to_form_params`Georgi Georgiev2018-07-161-2/+2
| | | | | | | | | `button_to` was throwing exception when invoked with `params` hash that contains symbol and string keys. The reason for the exception was that `to_form_params` was comparing the given symbol and string keys. The issue is fixed by turning all keys to strings inside `to_form_params` before comparing them.
* Use consistent spacing in actionview helper docs [ci skip]Olivier Lacan2018-04-011-1/+1
| | | | | | | | The spacing in these comments is fairly inconsistent. Array argument contents are often separated with a space from the array literal brackets but in several cases the Hash literal curly braces are tangent to their contents which makes the documentation harder to read in some cases.

| | | | | | 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.

* use path escaping for email addressesAaron Patterson2015-09-041-1/+1
| | | | | | 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.
* Optimize hash keyschneems2015-07-291-1/+1
| | | | | | No idea why on earth this hash key isn't already optimized by MRI, but it isn't. :shit: This change buys us 74,077 bytes of memory and 1,852 fewer objects per request.

| | | | | | | | | | | | | | | | | | | | | stevenspiel/link_to_if_block_helper_addition" This reverts commit d459b001b43d25053e7982e96eb8383538a6e358, reversing changes made to 4d4950fae9e2a6970b5f1793aadc56a0b44e28a3. :sweat: The block is not supposed to be passed to `link_to`. It's used for a customized behavior of the `condtion = false` case. The docs illustrate that like so: ``` <%= link_to_if(@current_user.nil?, "Login", { controller: "sessions", action: "new" }) do link_to(@current_user.login, { controller: "accounts", action: "show", id: @current_user }) end %> ```

| | | | No need to merge hashes when simply setting options does the job.
* 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.
