instance method
parameterize
Ruby on Rails edge
Since v3.0.20Signature
parameterize(separator: "-", preserve_case: false, locale: nil)Replaces special characters in a string so that it may be used as part of a ‘pretty’ URL.
If the optional parameter `locale` is specified,
the word will be parameterized as a word of that language.
By default, this parameter is set to `nil` and it will use
the configured `I18n.locale`.
```
class Person
def to_param
"#{id}-#{name.parameterize}"
end
end
@person = Person.find(1)
# => #<Person id: 1, name: "Donald E. Knuth">
<%= link_to(@person.name, person_path) %>
# => <a href="/person/1-donald-e-knuth">Donald E. Knuth</a>
```
To preserve the case of the characters in a string, use the `preserve_case` argument.
```
class Person
def to_param
"#{id}-#{name.parameterize(preserve_case: true)}"
end
end
@person = Person.find(1)
# => #<Person id: 1, name: "Donald E. Knuth">
<%= link_to(@person.name, person_path) %>
# => <a href="/person/1-Donald-E-Knuth">Donald E. Knuth</a>
```
