New Ruby on Rails Gem Announced by Mindfire Solutions

Mindfire’s Ruby on rails development team has created a gem called “Survey” and shared it in GIT (GIT link : https://github.com/mindfire-solutions/survey). Through this gem anyone can run a survey – all you need to think of is a set of questions and answers, rest all you need to do is add this gem to your Rails application.

Mindfire has been working in Rails application development for more than 2 years now and our development team has been contributing to the knowledge base by sharing our learning with the community at large through articles and tips (on new or useful things we learned during application development). This is one more step in that direction where we realized that there are no survey gems available for quick use by Rails developers worldwide, so we created one and shared in GIT.
Prerequisites for using this gem are:

• Ruby 1.9 or higher
  
• Ruby on Rails 3.1.3 or higher
  
• Application must have an authentication system with admin and normal user privileges.
  
• As we are using jQuery in the gem, so your application must support (include) jQuery-rails gem.
  
  

Details of the Survey gem:
Survey is composed of various modules those are listed and explained below:

1. Categories: All the questions and the answer sets are categorized. An admin user can add categories and a normal user can just view the categories.
   
   
2. Questions: Questions are the basic module of Survey. Questions can only be added by an admin user. They are broken into following types:
   

• Text Box: A question with a text box as an answer field.
  
• Text Box (Date): A question with a textbox and a calendar. Accepts only date as answer.
  
• Drop Down: A question with a drop down of choices. One of the choices needs to be selected to answer the question.
  
• Check Box: A question with check boxes. When a question can have multiple answers.
  
• Radio Button: A question with radio buttons. It can be used for selecting one out of multiple options.
  

3. Selections: Selections are the pre-defined choices/options for the questions of types Drop Down/ Check Boxes/ Radio Buttons etc. While creating a question if one chooses the question type to be any of the above three, a link is provided for adding a selection. A question can have as many selections as needed.
   
   
4. Validations: For the questions with Text Boxes, we can limit the input by adding validations. Validations can be chosen from the pre-defined list that appears if the question type is Text Box.
   
   
5. Question Sets: A Question Set is set of questions and sub-sets. Each question/sub-set that is added to the question set is called a Question Set Item. A Question Set is classified as follows:
   

• Assembly: A question set that cannot be integrated into other sets. Only Assembly Question Sets can be evaluated.
  
• Sub-Assembly (Sub-set): A question set that can be integrated into other sets.
  

6. Question Set Items: A question set item is any item that is being added to the question set. It can be a question or Sub-assemble question set.
   
   
7. Conditions: If the question set item is a question then we can add a condition based on the choice a user would made. For example, if the item is a question that states “Which car do you own?” and the selections are “A. Skoda, B. Audi, C. VolksWagon etc” now we can add condition if the user chooses selection A then we can show a question/set of questions, if user chooses B then we can show a different set/question or may be nothing. A condition can be applied to a question with Text Box too, but instead of using selections as a base the validations would be considered. If the question type is Radio/Dropdown the multiple selections in a condition would mean, if either of the selections. While in case of check box multiple selections would mean all of the selected options need to match with the user selections. Text Box (Date) type questions do not have any conditions.
   
   
8. Evaluation: Evaluation is sort of answering the questions in a set. A published and assembly type question set can only be evaluated. Any user can participate in the evaluation of a question set. Though they can view/edit evaluations made by them, they are not allowed to view evaluations made by other users in the system.

Hire Ruby on Rails Developer

If you are planning to hire Ruby on rails developers then Mindfire solutions is the right choice for you. Since its (RoR) public release in 1995, Ruby on Rails developers have creatively experimented with the application framework to make it highly competitive and user-friendly. Also known as RoR, Ruby on Rails is an open source web development software that uses the Ruby programming language. It uses the model-view-controller (MVC) architectural pattern for independent input and presentation environments. Rails framework incorporates a fully-dedicated Ruby web server, Rake build system and a wide range of web development tools.Ruby on Rails (RoR) is a programming language used to build interactive and engaging web applications. Rails is an open source web application framework written in Ruby language. It slashes development time and increases the simplicity of coding for dynamic web sites. RoR is a widely used programming language capable of providing rich user experience.

A Ruby on Rails developer has access to the following exclusive features over other programming languages:

• DRY: The Don’t Repeat Yourself feature aims at minimizing the repetition of information of any kind. Ruby on Rails accesses information from the source database. Thus, a Ruby on Rails web developer does not need to specify information in terms of column names.
• COC: With Convention over Configuration in place, Ruby on Rails developers need to name only related tables and the database is updated automatically. This helps in speeding up the coding process.

A RoR developer has to understand the underlying object-oriented environment. In Ruby, every bit of information and code is identified by their instance variables (properties) and methods (actions). It is tough to find an expert ruby on rails developer and more difficult to hire ruby on rails developer to work for your project. We at Mindfire have a rich pool of ruby on rails (RoR) developers who have strong work experience and are experts in RoR.
