转义符<％= h（“”）％>以及如何在Ruby on Rails中处理双引号

Question

This might be a simple question to answer, but I couldn't find the answer.

In Ruby on Rails, I thought the helper function would help escape special characters.

Example: " She's the one that took me "to" "

Code wise: <%= h("She's the one that took me "to" ") %>

However, the double quote won't allow me to display the code on the browser and gives me an error.

I thought the h() is an alias for html_escape() and they convert the following 4 characters

 <   >    &    "

into

<   >  &  "

Is there something i'm missing with using double quotes?

Any advice is appreciated Thanks, D

Answer 1

The problem is that your double quote around the word to is closing the double quote opened at the beginning of the string. Try this:

<%= h("She's the one that took me \"to\" ") %>

Or, to avoid having to backslashify the internal double quotes, you could use the % syntax for creating the string:

<%= h(%[She's the one that took me "to" ]) %>
