I would like to display nice URL in address bar and avoid spaces to display like %20
Here is an example:
Is it possible to replace these spaces with a dash ?
Something like: /BANQUE/International-Ledger
Maybe something to do in the routing ?
Thanks.
You dont want to replace spaces in generated route, you want to not generate them in the first place.
What is your "International Ledger" ? If it is action, then use [ActionName("International-Ledger")]
If it is some kind of product or category of product, is it good practice dont use product name for URL, but some "token" generated from name, for example with regex, replacing spaces with dashes, special letters with theirs basic alphabet variants, and maybe some unique identifier to prevent conflicts of products with the same name.

I like the friendly id gem but one problem i'm seeing is when I type in a url with a capitol letter in it such as /users/Joe-Blogs it cant find the page. Its a little trivial but most sites can handle something like this and will generate the page whether it has a capitol letter or not. Does anyone know a fix for this?
Edit: to clarify this is for when users enter a url manually and put capitals in it just because its a name like author/Joe-Blogs. I've seen other sites handle this but rails seems to just give a 404.
friendly_id uses parameterize to create the slugs.
I think the best way to solve your problem is to parameterize the params before using it to find.
# controller
User.find(params[:id].parameterize)
Or parameterize the url where the link originated from.
As an addition to Vic's answer, you'll want to look at url normalization:
The following normalizations are described in RFC 3986 to result in equivalent URLs:
Converting the scheme and host to lower case.
The scheme and host components of the URL are case-insensitive. Most normalizers will convert them to lowercase.
Example: HTTP://www.Example.com/ → http://www.example.com/
In short - it's against convention to use capitalization in your urls.
You may also wish to look at URI normalize; more importantly, you should work to remove the capitalization from your URLs:
URI.parse(params[:id]).normalize
I am getting confused while writing URLs with hyphens. It is conflicting with GET parameters.
For instance, I have a long book name in URL, with spaces replaced by hyphens, like the-famous-world-records-of-athletics. After this I am getting error in pagination also separated with hyphens.
Please suggest how I can write URLs in given stage:
example.com/vc.php?book=the-famous-world-records-of-athletics
example.com/vc.php?book=the-famous-world-records-of-athletics&page=1
example.com/vc.php?book=the-famous-world-records-of-athleticstopic=jumping-and-racing&page=2
Wishing to write as:
example.com/the-famous-world-records-of-athletics.html
example.com/the-famous-world-records-of-athletics-1.html
example.com/the-famous-world-records-of-athletics-jumping-and-racing-2.html
A minus is perfectly valid in an URL, it is a so-called 'unreserved' character.

If you really need to replace them, I'd replace them with %2D, just like you would replace a space with %20.
I am preparing a special string, in which keys are values are concatenated like below:
username=foo&age=24&email=foo#bar.com&homepage=http://foo.com
& is the separator for two key=value pairs
value is url encoded
I have a scenario where there are multiple home pages for a user.
I want to specify multiple urls for the homepage key
name=foo&age=24&email=foo#bar.com&homepage=url1<some_safe_url_separator_char>url2<some_safe_url_separator_char>url3
We have no control/idea over what url1, url2, .. may contain?
What is a good choice of some_safe_url_separator_char?
In other words I am not looking for a safe character to be used IN a url, but a safe character to be used to SEPARATE two urls in a string
well you can use URL re-writing for this .
It will make a URL that will be safe as it will hide the name of parameters
For refrence you can use URL rewriting
URL rewriting will make a url seprated by '/' and its tough to be decoded by an external person.

URL rewriting for beginners
I'm using playframework, and I hope to generate complex urls like stackoverflow. For example, I want to generate a question's url:
http://aaa.com/questions/123456/How-to-generator-a-complex-url
Note the last part, it's the title of the question.
But I don't know how to do it.
UPDATED
In the playframework, we can define routes in conf/routes file, and what I do is:
GET /questions/{<\d+>id} Questions.show
In this way, when we call #{Questions.show(id)} in views, it will generate:
http://aaa.com/questions/123456
But how to let the generated has a title part, is difficult.
With playframework it's easy to generate such url. In your routes file you add this :
GET /questions/{id}/{title} YourController.yourMethod
See the doc in playframework site about routing for more info
In your html page :
<a href="#{YourController.yourMethod(id,title.slugify())}">
slugify method from JavaExtensions, clean your title from reserved characters (see doc)
It a server-side url rewriter does. In case of SO it doesn't matter you type {...}/questions/4698625/how-to-generate-complex-url-like-stackoverflow or {...}/questions/4698625 - they both redirects to the same content. So this postfix is used just to increase readability of a url.
To see more details about url rewriting, see this post.
UPD:
to generate such a postfix,
take a title of the content,
shrink multiple whitespaces into single
replace all whitespaces with dash (-)
remove all non-letter symbols from a title
Better to perform this operations with Regular Expressions
I have some form on the website where users can add new pages. I must generate SEO friendly URLs and make this URLs unique.
What characters can I display in URL, I know that spaces I should convert to underscore:
" "->"_" and before it - underscores to something else, for example:
"_"->/underscore
It is easy make title from URL back.
But in my specific title can be all characters from keyboard, even : ##%:"{/\';.>
Are some contraindications to don't use this characters in URL?
Important is:
-easy generating URL and title from URL back (without queries to database)
-each title are unique, so URL must be too
-SEO friendly URLs
Aren't you querying the database to get the content anyway? In which case just grab the title field in the same query.
The only way to reliably get the title back from the URL is to 'URL encode' it (in PHP you use the urlencode() function). However, you will end up with URLs like this:
My%20page%20title
You can't replace any characters because you will then not have unique URLs. If you are replacing spaces with underscores, for example, the following titles will all produce the same URL:
My page title
My_page title
My_page_title
In short: don't worry about one extra database hit and just use SEO-friendly URLs by limiting to lowercase a-z, 0-9 and dashes, like my-page-title. Like I said, you can just grab everything in one query anyway.
