Rails 3 - Friendly params in url (GET) - ruby-on-rails

I have a rails 3 app and now i implementing filter for my catalog. Filters form pass data to controller through GET request. As a result i have link like this in my browser after i submit
my form (apply search):
http://localhost:3001/shoes?filter%5BShoeBottomType%5D%5B%5D=2&filter%5BShoeClassification%5D%5B%5D=1&filter%5BShoeClassification%5D%5B%5D=2&filter%5BShoeElation%5D%5B%5D=3&filter%5BShoeElation%5D%5B%5D=4&filter%5BShoeElation%5D%5B%5D=5&filter%5BShoeLiningColor%5D%5B%5D=2&filter%5BShoeLiningColor%5D%5B%5D=3&filter%5BShoeLiningColor%5D%5B%5D=4&filter%5BShoeTopColor%5D%5B%5D=1&filter%5BShoeTopColor%5D%5B%5D=2&filter%5Bonly_action%5D%5B%5D=1&page=2
Is there a way to do URL more beautiful?
PS i dont want use POST request, because I read that it is bad for SEO

TLDR: just leave it.
HTML forms serialize in a straightforward manner; the parameters are named after the HTML elements. The actual issue here is how the form elements are named. It looks like they have names like filter[ShoeBottomType][]; look into your HTML to see the name attributes. Since you're in Rails, I'm guessing you having a filter hash passed to your Rails controller method as a single argument, and since Rails expects hashes to use a certain URL format for hashes and arrays (it has to know how to deserialize it from the request), the form helper writes the form that way. And yours is especially complicated because the hash values are arrays, hence the extra set of brackets. Then it's URL encoded and you end up with an ugly mess.
You could avoid some of this problem by passing the inputs individually back to the controller instead of as a big hash. Something like:
def index
shoe_bottom_types = params[:bottom_types]
shoe_classifications = params[:classifications]
shoe_elations = params[:elations]
...
which will get you to: /shoes?bottomTypes[]=1&bottomTypes[]=2.... That doesn't seem much better, and now your controller is all gross. And I don't see how you're going to get rid of the brackets entirely if you want to have more than one of the same filter. I guess you could get crazy and do your own parsing in your controller, like breaking apart shoeBottomTypes=1|2, but then you'll have to do your own form serialization too. Again, just not worth it.
Backing up for a sec, the SEO stuff doesn't make much sense. Search engines won't fill out your form; they just follow links. The real reason you should use GET is that (presumably), submitting your form doesn't have side effects, since it's just a search. See here; it's important to use the right HTTP methods. If you use POST, you'll get weird warnings on reloads and you won't be able to bookmark the search.
Backing up even further, why do you care, especially now that SEO is out of the picture? Just as a quick demo, I did a google search for the word "thing" and this was the URL:
https://www.google.com/#hl=en&output=search&sclient=psy-ab&q=thing&pbx=1&oq=thing&aq=f&aqi=g2g-s1g1&aql=1&gs_sm=3&gs_upl=764l1877l0l1980l6l6l0l0l0l0l89l432l5l5l0&bav=on.2,or.r_gc.r_pw.r_cp.r_qf.,cf.osb&fp=220ef4545fdef788&biw=1920&bih=1086
So URLs for form submissions can be long. The user won't even look at it.
The only possibility I can think of for why you'd care about the length/ugliness of your URL here is that you want, separately from the form, to create links to certain searches. There are several ways to handle that, but since I don't know whether that's relevant to you, I'll let that be a follow-up.
So bottom line, it looks like I'd expect, and trying to fix it sounds ugly and pointless.

If you do not want to use a POST request, then there is no other way then to put the form values in the URL -- they have to get to the server one way or another.
On the other hand however, I do not see why doing a POST would be bad for SEO and I would love to see the article that stated so.

My suggestion is that you could add some custom routes to beautify your urls.
For example :
http://localhost:3001/shoes/Type/2/Classification/1,2/Elation/3,4,5/LiningColor/2,3,4/TopColor/1,2/only_action/1/page/2
This is far much shorter than your initial URL ;)
The counterpart is that, as far as I know, you have to use always the same order for params in your url.
The routing rule is the following :
match "shoes/Type/:type/Classification/:classification/Elation/:elation/LiningColor/:liningcolor/TopColor/:topcolor/only_action/:only_action/page/:page" => "shoes#show"
You can retrieve the passed values in params array. You have to split the string containing , in order to retrieve the multiple values.

a nested route or done as a parameter

I have the following call:
http://localhost:3000/arc/v1/api/menus/51/only_items_with_notes
and I'm curious what is the preferred structure of the url - This reads fine and is totally clear what it means. But I am not sure if this is the canonical way to do this. One issue is that it does proliferate the routes.rb file. I have:
get '/menus/:menu_id/only_items_with_notes' => 'api_menus#only_items_with_notes'
One think I don't like is that it reads a bit like a pseudo nested attribute. What is the proper, canonical way to do this?
That’s pretty deep nesting. What other routes do you have?
In the absence of more information, I’d suggest that only_items_with_notes is really a filter on the functionality of the index action. You can use a query parameter to restrict the items to those with notes.

Any problems with using a period in URLs to delimiter data?

I have some easy to read URLs for finding data that belongs to a collection of record IDs that are using a comma as a delimiter.
Example:
http://www.example.com/find:1%2C2%2C3%2C4%2C5
I want to know if I change the delimiter from a comma to a period. Since periods are not a special character in a URL. That means it won't have to be encoded.
Example:
http://www.example.com/find:1.2.3.4.5
Are there any browsers (Firefox, Chrome, IE, etc) that will have a problem with that URL?
There are some related questions here on SO, but none that specific say it's a good or bad practice.
To me, that looks like a resource with an odd query string format.
If I understand correctly this would be equal to something like:
http://www.example.com/find?id=1&id=2&id=3&id=4&id=5
Since your filter is acting like a multi-select (IDs instead of search fields), that would be my guess at a standard equivalent.
Browsers should not have any issues with it, as long as the application's route mechanism handles it properly. And as long as you are not building that query-like thing with an HTML form (in which case you would need JS or some rewrites, ew!).
May I ask why not use a more standard URL and querystring? Perhaps something that includes element class (/reports/search?name=...), just to know what is being queried by find. Just curious, I knows sometimes standards don't apply.

Struts 2 - is there any way to escape HTML in input fields?

When I allow a user to enter text using s:textfield, he can enter something like <b>Name</b> or something like \Me/. I want that these should be escaped before I am saving them to the database. When we retrieve them, the escaping is done automatically, but I want it to happen also when we are saving it.
I was trying to return a json output from my action class, but due to a name \a/ stored in my database, wrong json was being formed. This would have been avoided if the name had been escaped before being saved into the database.
You can use StringEscapeUtils. You can call escapeJavascript(textfield) in your action and then store it into the database.
#Daud, The problem you explained is called Cross site scripting or XSS.
And I think you should use Filters to clean the request parameters. This is the most sophisticated way. You can call these filters for the actions which are posting some parameters via request.
Visit my blog to see how to avoid XSS threat using Filter approach.
I also faced this issue when our project was tested by well known firm specializing in security testing and they suggested this filter approach.
You can give it a try.

How to access AJAX hash values in ASP.NET MVC?

I'm considering using the hash method to create static urls to content that is managed by ajax calls in a Asp.Net MVC. The proof of concept i'm working on is a profile page /user/profile where one can browse and edit different sections. You could always ask for the following url /user/profile#password to access directly to you profile page, in the change password section
However, i'm wondering if i'm not starting this the bad way, since apparently i can't access the part after the hash in any way, except by declaring a route value for the hash in global.asax. So i'm wondering if this is the right way to access this part of the url?
Am i supposed to declare a route value, or is there another way to work with hash values (a framework, javascript or mvc)?
Edited to add:
In pure javascript, i have no problem using the window.location.hash property, i'm not sure though how standard it is in today's browsers, hence the question about a javascript framework/plugin that would use it.
The thing is that the part that follows the hash (#) is never sent to the server into the HTTP request so the server has absolutely no way of reading it. So no need to waste time in searching for something that doesn't exist.
You could on the other hand tune your routes to generate links that contain the hash part so that client scripts can read it.
Send the hash value document.location.hash as a parameter to the controller action of your choice.
This can be done in the code if needed...
RedirectResult(Url.Action("profile") + "#password");
should work fine

Render different template based on where request was called from?

I'm calling a controller action to do a search with an AJAX request from 2 different pages and want to render a different rjs file based on which page requested the action. I could just make 2 actions to do this but it doesn't seem very DRY when it's the same code in the action just need different rjs as it's displaying the search results differently in the view.
Using Rails 2.3.4 and Ruby 1.8.7
If I understand your question correctly, three ways come to mind to solve this:
In your action, check the current request's http_referrer and try to figure out what page initiated the request. Depending on how you've got your routing set up, this may or may not work, but it does have the advantage of being pretty simple to do.
Have your AJAX request include an extra GET parameter to identify which page the request is from. Then, have the Rails action test for that parameter, and render RJS accordingly.
Do something clever with Routes and have page A hit the action from one distinct URL, and page B hit the action from another, and include the page identification parameter in the route configuration.
My preference would be for approach #2, as it seems way less likely to break randomly when your routing changes, and #3 strikes me as being overly complicated. There's probably a million other ways to do this, but those are the three that came to mind right off the bat. Hope that helps...
How much code is in the action? You could just factor that out into a common subroutine and call that from each action. It would keep the code simple and easy to understand, without resorting to clever tricks.
I usually do like #2 from Steven's answer, but with a twist. A filter in my ApplicationController attributes a custom mime type corresponding to the extra parameter.
That way, the names of my view files are clearer (i.e.: "show.employees-autocomplete.rjs", "show.quotation-autofill.rjs").
