In the thymeleaf documentation there's only option to get request parameters from urls which looks like,
https://example.com/getUser?id=10
I can use ${param.id[0]} to access the user id in thymeleaf whereas if I have a REST-style url like this,
https://example.com/user/10
How can I access the user id(10) in the page using thymeleaf with the above URL? Of course I can set a model attribute to access the id of user in the page. But just wondering if there any better way to do this in thymeleaf in order to minimize the code?
Well there is no direct helper AFAIK but your best shot is something like this:
${#strings.listSplit(#httpServletRequest.requestURI,'/')[1]}
note that 1 which is the list index of splitted url varies according to your url structure.
Note that #httpServletRequest.requestURI gives you user/10 and listSplit gives you [user, 10]

I have a rails application in which I would like to generate a url based on a parameter, but for that parameter to be hidden from public view. So essentially working like a POST request but being able to be typed in like a GET request.
For example using a QR reader I could have the address as www.site.com/qr?lot_no=18007 but when a user scans the QR image it only shows www.site.com/qr but displays the results related to lot_no=18007.
Not sure if this is possible or not. But any help would be greatly appreciated.
If all you want to do is to prevent it from showing up in the address bar of the browser, you could use Rails.ajax to make the request dynamically through Javascript.
That will at least hide it from casual inspection, but there is no way to suppress the parameters from the query string on a GET completely, so anyone looking at the Networks tab in the browser (for example) would still see them.
Another alternative would be to encrypt the parameter value.
Maybe the Friendly id gem may be of help here
The following is an example of it's use is
http://example.com/states/washington
instead of:
http://example.com/states/4323454
This is not going to work with a post request as you mention though. It is a way of using a get request that would normally send an id in the params hash to retrieve existing records.
The gem can be found here https://github.com/norman/friendly_id
It is well maintained and up to date
Configure different route for public facing URL, the URL should include encrypted lot id as a path param.
routes.rb
get '/view_lot/:id' => 'QrCodesController#view_lot`, as: :public_view_lot
now in QrCodesController add action view_lot
def view_lot
encrypted_id = params[:id]
id = decrypt_it(encrypted_id)
#lot = Lot.find(id)
render "your_template"
end
in you QR code generation, pass URL to above action with encrypted id like public_view_lot_url(lot_id)
I have a website built from Ember.js. A user can access a page through URL http://..../view?showTitle=true. However I don't want to explicitly expose the parameter showTitle=true to the user (meaning user will only see http://..../view). This URL is automatically generated and serves as a redirect destination URL. So, I have to remove it manually somewhere before the page load. But I still need this value of this query parameter to query data. Is there a way to achieve that (A example would be great)? What about do it without refreshing the router?
Actually, an example of your scenario would be greater :)
There are some other ways to store data while transitioning to a route. Such as: storing the params in transition object or storing the value in a service. Create a redirection route, use beforeModel hook to grab the value from query params then do a redirection to the real route.
A working example is: ember-twiddle-1
By the way, even if you don't describe your queryParamsin your routes, you can access them via transition.queryParams. This seems a bit hacky. But it works: ember-twiddle-2 (Note: It doesn't work in the same route.)
Updated:
At the setupController hook you can override the controller parameters. So you can remove the parameters from the url. ember-twiddle-3
I'm creating a dynamic website which is displaying many products. There are also filters like price (from - to), year (from-to) etc. I need to put # symbol before the filter parameters in URL because of Googlebot indexing. But I have no idea how to do it and found no documentation on the internet.
I think it could be done with AJAX script but I don't know where to start.
The question is:
How do I insert a # hash symbol before parameters in URL?
I've got this:
http://domain.com/pd/?rps=100&a=2001
and I need to make it look like
http://domain.com/pd/#rps=100&a=2001
Why do you want to replace the "?" with "#". For well optimised url to seo, you can leave them unchanged. You can also use Google Webmaster Tool to declare your url parameters. Here is another resource for you to optimize your url :Faceted navigation
I want to pass a variable in my URL but not show it in the URL for SEO purposes
e.g www.mywebsite.com/Search?city=NYC should looks like www.mywebsite.com/Search and still be able to retrieve the value of "city" on the page.
Thanks
Simply use a POST request and you're done. However, is a common pratice to use GET request for search forms because the user can bookmark the url. Using POST, this isn't possible.
I just used Rewrite rules to accomplish this.
I am accessing a set of websites using variables
<cfhttp url="http://website.com/index.php?title=#var1#:#var2#&action=edit##EditPage" method="GET">
Some pages do not provide the data I need and instead of #EditPage in the URL show a fragment
edit&redlink=1. I want to treat these pages differently. How do I go about identifying them?
The hash "#" used in URL is used by browsers and not servers. Typically when a browser sees the hash in the URL it will jump to either an anchor on the page with the same name, or an element with that id. Exceptions, are when javascript is used to modify the page dynamically based on the hash.
If I'm understanding you correctly, what you want to do is construct the URL in a separate variable first. Something like URLtoGet. Then, you can use cfif to switch on whether that constructed URL contains the fragment you specified. Look into contains(), find(), and findNoCase() to determine which is the best option for you.
