Passing array of parameters through get in rails

Question

How do I pass array of parameters through Get method in rails? Currently my URL loocs like this:

http://localhost:3000/jobs/1017/editing_job_suites/1017/editing_member_jobs/new?ids[]=1025&ids[]=1027 

How can I pass the array with Get method but avoid ?ids[]=1025&ids[]=1027 part.

Request is being sent with javascript window.open method. Is there any workaround to send not ajax Post request.

Answer 1

You should stick to using a GET request if you are not changing the state of anything, and all you want to to access a read only value.

To send an array of ids to rails in a GET request simply name your variable with square brackets at the end.

//angular snippet  $http.(method:'GET',   ...   params: {'channel_id':2, 'product_ids[]': productIds}     //where productIds is an array of integers   ... ) 

Do not concatenate your ids as a comma separated list, just pass them individually redundantly. So in the url it would look something like this:

?channel_id=2&product_ids[]=6900&product_ids[]=6901 

url encoded it will actually be more like this:

?channel_id=2&product_ids%5B%5D=6900&product_ids%5B%5D=6901 

Rails will separate this back out for you.

Parameters: {"channel_id"=>"2", "product_ids"=>["6900", "6901"]}

No, GET can only put variables on the url itself. If you want the URL to be shorter, you have to POST. That's a limitation feature of HTTP, not Rails.
