This project uses MIT-LICENSE.

This was a test case to see my way of implementing a certain task. The given requirements are shown below. The test case implyed that no further guidance could be asked from the examiner.

My developper remarks are prefaced with *dev. remark:* and in font style italic.

Write a Rails engine to track orders from DHL and FedEx

##Requirements

• the Engine should be able to populate a button “track your order” to the main Rails app √ *dev. remark: interpreted button as form, according to the following requirements*

• Helper method should be called with or without any trackingnumber √ *dev. remark: as a helper method is not called with user input, this helper method is interpreted to create a form*

  • with: show the tracking information directly √ *dev. remark: result page not layouted to save my time, as example is already given with the form*

  • without:

    • popup a modal form where users can enter one DHL or FedEx tracking number, form should be shown using ajax √

    • after submitting, the engine should check if it is an DHL or FedEx tracking code √ *dev. remark: possibility to have different partials according to shipping company; shown in a short message on result page*

###Additional requirements

- Only valid tracking numbers are allowed to submit. √
- Layouting with bootstrap √ *dev. remark: only form; rest omitted to save time*
- Using an algorithm to check if it is an DHL or FedEx tracking number and if they are valid ! √ *dev. remark: most simple check according to my knowledge of validation criteria*
- After submitting
 - Show the current status of the order √ *dev. remark: as last field, could be more highlighted but omitted to save time*
 - Show the previous statuses in a table √ *dev. remark: rudimentary implementation serving as example; no api was given*
 - Provide a helper button to access this form from the main Rails app. *dev. remark: interpreted as written above*
- You can use this pages for example for checking statuses: *dev. remark: i will omitt unneccessary details of layouting and process complexity which are not related to the implementation to save your and my time*
