I have a highcharts chart in a div. I want to make it easy for users to tweet it out. How could I do this? I was thinking of a screenshot gem then integrate the twitter API. Is this possible? Or is there a better way? Thank you.
You could render the image server side, and then share it out via some client side JS tools such as Share This.
Render HighCharts on the server: http://www.highcharts.com/docs/export-module/render-charts-serverside
Once you have the image, use it for sharing by including it in your HTML.
Share This docs: http://support.sharethis.com/customer/portal/articles/475079-share-properties-and-sharing-custom-information#sthash.QCmTvDs6.dpbs
This may be a slightly different approach than what you were looking for, but it works.

I am trying to get twitter feeds in to my shopify site. I want to get the feeds and style them as I want and thus cant use a app.
I know how to do it using PHP but can not use that code in shopify and looking for a way I can use OAuth in shopify and get the feeds. I tried the shopify docs but without an example its kinda hard to actually get my head around it.
http://docs.shopify.com/api/tutorials/oauth
Thats the link I am using as a guide. If anyone can direct me to an example which might be similar that would be awesome. (google didnt seem to be that helpful this time either)
Cheers
I know you said you didn't want to use an app, but can I suggest taking a look at Twitify? You can use custom CSS to style your tweets. Also see discussions about Twitify here and here.
Twitter changed their display guidelines and policies on embedding of tweets on websites in June 2013. One of the themes I used for a client earlier in the year had custom styling of tweets, and they have now changed it to use the official Twitter widget to meet the new guidelines. In fact, the images on the Shopify theme store show how it used to look before Twitter changed things:
And after:
I think using an app like Twitify would be the easiest way to deal with these changes to embedding tweets.
Thanx for the suggestion. I did take a look at that before I posted this question. This is a project for a client and I dont think getting a plug in is a viable option. Anyways I found a work around.
Hosted the file on a server and then accessed it. So that resolved the problem. :)
I used node.js to write the script and get the posts as required.
Cheers.
you can use the app for that Twitify https://apps.shopify.com/twitify or you can Embed a Twitter feed in your online store
Go to your Twitter settings.
Click Widgets to open the widgets menu.
Create a new widget, following Twitter's instructions.
Copy the embed code.
When using FB or Google + I can paste a link of any website into the status update box and it will instant load information about that website with the option of flicking through thumbnail images.
How can I go about achieving this in ruby on rails? All my searches seem to bring up php methods on how to do this.
For grabbing video data info I use the Ruby Open Graph Protocol gem. Is there any thing for grabbing data the way FB and G+ do? If not is there a standard way this is done in rails/ruby, if so.. how is this done?
Kind regards
I think you're looking for something like oembed. I've found a gems for that, so I propose you to take look at it: https://github.com/judofyr/ruby-oembed or https://github.com/embedly/embedly-ruby
You should likely use a gem like http://nokogiri.org/
It allows you to work with a html page just as you would do with jQuery. Very handy.
I may fall under the list of possible duplicates but still i could not find the answer according to my req.In my rails application i have some web pages with a link of print option.
Now what i need is when i click on this print ,i should get a screen shot of the current web page and a popup box to save the image .Is there any plugin available for the same.
Also any queries for code are welcome
Thanx
You could go for phantomJs. Where you can alter the page HTML, manipulate CSS, insert & call javascript snippets, the way you need it.
Good documentation available and also you can find great deal of help in stackoverflow-phantomjs

May i suggest that you use http://www.w3.org/TR/css-print/
if you want to make a screeenshot you have to work with the user env, so i suggest you look at this topic How do I take screenshots of web pages using ruby and a unix server?
I'm currently parsing twitter feeds through my rails app and wondering how it would be possible to follow links in the tweets and scrape the external content (for example, if the tweet contains a link to an article on TechCrunch, follow that link to the article and scrape the title and body content of the article). Flipboard for iPad is a perfect example of this.
I'm familiar with screen scraping using Nokogirl / Mechanize, but trying to figure out how to accomplish this in a way it could work regardless of where the link in the tweet is linking to (whether it be to TechCrunch, or Flickr, etc...).
Any thoughts / insights would be much appreciated!
Many of the major content providers provide a oembed endpoints. Take a look at the oembed_links gem. From the readme:
It allows you to easily parse text and
query configured providers for embedding information on the links
inside the text. A sample configuration file for configuring the
library has been included (oembed_links_example.yml), though you
may also configure the library programmatically (see rdocs).
If you use oembed_links in conjuction with http://oohembed.com/ you'll have dozens of content providers handled for you. You can easily write a custom provider to handle the rest.
Similar to Facebook's UI, I am attempting at generating a preview image from an external linked website. So that when a user types in a url he is linking, the UI will by default, scan that site for an img and scrape a preview thumb.
Is there a specific name for this technique? Or can anyone point me in the direction of learning this?
Thanks so much!
Its called scraping. There is a library called scrAPI.
Here is a code example http://crunchlife.com/articles/2007/08/13/code-snippet-ruby-image-scraper
There are a couple different options when it comes to page scraping. Another one to check out would be nokogiri, http://nokogiri.org/. You can find tutorials on how to use it at http://nokogiri.org/tutorials.
Instead of grabbing an image from the site, why not grab the image of the entire page? You could make use of a free screenshot service like http://www.websnapr.com/ or http://www.thumbshots.com/ among others. In one application, I use that for my preview image, and use nokogiri to scrape the page title and description. Just an idea.
