The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

word to html: document conversion using ruby on rails

Asked by gt9 in RubyOnRails, Ruby Scripting Language

Tags:

Hi,

I am trying to convert MS word files into an HTML format. I have used Abiword and OpenOffice (PyDocConverter) for the document conversion. I am able to convert document using both tools. I need some help regarding storage, rendering, and caching.
1. Where should I store the converted page? Right now, I am using /tmp directory of my system. Will it be good idea to store it in the application's public directory?
2. I would like to open HTML document in a new browser tab or window. Right now I am using ActionController API - send_file and render methods to serve this HTML file. However, they do not seem to offer 'open in new tab' option. Is there any option I can serve this in a new tab? My related question : http://www.experts-exchange.com/Programming/Editors_IDEs/RubyOnRails/Q_23826992.html?cid=239
3. Assuming that many users will try to access this document, how can I use caching?

I am attaching my code snippet over here. Please suggest me any other issues to consider and/or improvements in this code.
