[RUBY] When continuous line breaks are displayed on the screen, the line breaks are combined into one.
1) Background </ font>
See the "Content Registration" section in the image below. There are 9 lines in total.
If you register this and display it with the ** simple_format ** </ font> method on another screen, it will be as follows.
How can I get the number of lines as registered? I thought about countermeasures.
2) Environment </ font>
| item | Contents |
|---|---|
| OS.Catalina | v10.15.4 |
| Ruby | v2.5.1 |
| Ruby On Rails | v5.2.4.3 |
3) Contents </ font>
** Correspondence 1) Create a helper method. ** ** I also saw other people's articles, but I made a helper as follows.
application_helper.rb
1 module ApplicationHelper
2 #In the case of consecutive line feed codes, the line feed tag is explicitly inserted because it is escaped.
3 def br(str)
4 str.gsub(/\r\n|\r|\n/, "<br />").html_safe
5 end
6 end
Use this helper by calling it as follows when displaying. Making it a helper is convenient because the cost of making it is low.
erb:test.html.erb
1 <div class="krown-value">
2 <%= br(@knowledge.content) %>
3 </div>
It is now displayed in 9 lines like this.
that's all.
