I would like to display a pdf in an iframe in one of my Rails projects. My current code is <iframe src="tmp/data.pdf"></iframe>, but when I go to this page, I get the error: "No route matches [GET] /Users//development//tmp/data.pdf".
data.pdf is in this location, so I think I'm doing something wrong with my routes file, and maybe I have to route the file to a path appropriately. I've tried playing around with a few things, but haven't had much luck so far. Can anyone provide any help?
Rails only exposes the contents of the "public" subfolder to the webbrowser so no code/configuration can be downloaded by any user...
Try putting the file there and it should work.
UPDATE 1
Also you need to note, that the "public" part does not have to be included in the URL. So in your case the url would be just "/data.pdf".

I am uploading PDF files using paperclip, how do I display them after?
This is the error I get:
ActionController::RoutingError (No route matches [GET] "/public/uploads/6/test.pdf"):
I mean ok I know it's a routing error but do I have to define a route for every file? it doesn't make sense to me
You do not have to define a route to it, just link to it properly just like you would an image
Your url linking to the asset is incorrect. Remove the /pulbic so it looks like below.
'/uploads/6/test.pdf'
I am using orchard 1.9 and I am building a service in which I need to get current URL.
I have OrchardServices and from that I can get the URL like so:
_orchardServices.WorkContext.HttpContext.Request.Url.AbsolutePath;
This works like a charm for pages/routes that I have created but when I go to the Login or register page (/Users/Account/LogOn) the absolute URL is / and I can't find anyway to get the URL or at least any indication that I am in the LogOn or Register.
Anyone knows how I could get the full url?
If I understand what your're asking, you could use the ItemAdminLink from the ContentItemExtension class.
You will need to add references to Orchard.ContentManagement, Orchard.Mvc.Html and Orchard.Utility.Extensions, but then you will have access to the #Html and #Url helpers.
From there you will have the ability to get the link to the item using:
#Html.ItemDisplayLink((ContentItem)Model.ContentItem)
The link to the item with the Url as the title using: #Url.ItemDisplayUrl((ContentItem)Model.ContentItem)
And you should get the same for the admin area by using these:
#Html.ItemAdminLink((ContentItem)Model.ContentItem)
#Url.ItemAdminUrl((ContentItem)Model.ContentItem)
They will give you relative paths, e.g. '/blog/blog-post-1', but it sounds like you've already got a partial solution for that sorted, so it would be a matter of combining the two.
Although I'm sure there are (much) better ways of doing it, you could get the absolute URL using:
String.Format("{0}{1}", WorkContext.CurrentSite.BaseUrl, yourRelativeURL);
...but if anyone has a more elegent way of doing it then post a comment below.
Hope that helps someone.
I am trying to download an image and displaying it in a view in rails.
The reason why I want to download it is because the url contains some api-keys which I am not very fond of giving away.
The solution I have tried thus far is the following:
#Model.rb file
def getUrlMethod
someUrlToAPNGfile = "whatever.png"
file = Tempfile.new(['imageprependname', '.png'], :encoding => "ascii-8bit")
file.write(open(data).read)
return "#{Rails.application.config.action_mailer.default_url_options[:host]}#{file.path}"
end
#This seems to be downloading the image just fine. However the url that is returned does not point to a legal place
Under development I get this URL for the picture: localhost:3000/var/folders/18/94qgts592sq_yq45fnthpzxh0000gn/T/imageprependname20130827-97433-10esqxh.png
That image link does not point anywhere useful.
My theories to what might be wrong is:
The tempfile is deleted before the user can request it
The url points to the wrong place
The url is not a legal route in the routes file
A am currently not aware of any way to fix either of these. Any help?
By the way: I do not need to store the picture after I have displayed it, as it will be changing constantly from the source.
I can think of two options:
First, embed the image directly in the HTML documents, see
http://www.techerator.com/2011/12/how-to-embed-images-directly-into-your-html/
http://webcodertools.com/imagetobase64converter
Second, in the HTML documents, write the image tag as usual:
<img src="/remote_images/show/whatever.png" alt="whatever" />
Then you create a RemoteImages controller to process the requests for images. In the action show, the images will be downloaded and returned with send_data.
You don't have to manage temporary files with both of these options.
You can save the file anywhere in the public folder of the rails application. The right path would be something like this #{Rails.root}/public/myimages/<image_name>.png and then you can refer to it with a URL like this http://localhost:3000/myimages/<image_name>.png. Hope this will help.
In a site I'm developing I have a page that presents a post based on the variable in the url:
http://www.mywebsite.com?id=18
So this would load the post who's ID is 18 in the mySQL database.
I would like the create the same effect, but with the url being something like:
http://www.mywebsite.com/articles/title-of-article-18/
Would there be a way to create these pages on the fly with dynamic post content, where the url would originally be created by:
"http://www.mywebsite.com/articles/" + postTitle
You are looking for mod_rewrite and rewriting of urls via htaccess.
What it does is it takes patterns from your url, and the htaccess file detects the pattern redirects that to http://www.mywebsite.com?id=18. Users still see the nice url.
The directory /articles/title-of-article-18/ will not actually exist, and the user never really reaches that location because the htaccess secretly changes the url that the server processes.

http://en.wikipedia.org/wiki/Rewrite_engine
or a random tutorial I found:

I think this is an easy question. I am using this useful Flash Document Reader called FlexPaper. I have it embedded in one of my Show pages. But when I click the a link on their tool bar to show the document in a new browser, it points to the following link:
http://example.com/intels/FlexPaperViewer.swf?ZoomTime=0.5&FitPageOnLoad=false&PrintEnabled=false&SwfFile=%2FPaper.swf
which doesn't work, I get the following error:
ActiveRecord::RecordNotFound in IntelsController#show
Couldn't find Intel with ID=FlexPaperViewer
but if I remove the "intels" from the path so the url looks like:
http://example.com/FlexPaperViewer.swf?ZoomTime=0.5&FitPageOnLoad=false&PrintEnabled=false&SwfFile=%2FPaper.swf
It works fine.
My question is what is the best way to handle this? Can you write a route that rewrites a url that starts with intels/FlexPaperViewer.swf and remove the intels prefix? What would that look like?
Is there a better option?
Juat a thought, how about placing the FlexPaperViewer.swf inside public/intels folder?
So the directory structure will be
<project-directory>/public/intels/FlexPaperViewer.swf
Doing this will make the link correct. It seems to be easier to do it this way.
Hopefully it helps.
EDIT
Another alternative will be to see how the link was generated, maybe there is a parameter that you can set when you embed the FlexPaper.
I am not aware of any route modification that can do what you want. Maybe someone else can help on this.
