ruby on rails - How to create custom label in 'options_from_collection_for_select' method? -

I want to modify the user's drop-down in view of the collection. Rather than just seeing the "Products" field, I would like to like it as a "Wonder product, version" or something like that.

Can this be done with the 'options_from_collection_for_select' method? / Code>

Controller:

  @external_tools = ExternalTool.all    / former> 
 model (via some different migration): 
 
  t.string: value t.string: validator t.string: example_answer t.boolean: Inaccurate, default => true t.boolean: is_file_upload ,: null => wrong, default => false add_reference: external_tool_questions ,: external_tool, index: true  
 
 I have tried: 
 
 
 
 I saw this document, but can not 
 
 
 I tried to guess now, but It is not working: 
 
 
 
 Code: 
 
  options_from_collection_for_select (@external_tools, "id", "product vendor")  
 
 (Also ... I can not understand how to select tags to work ... I'm also using a simpler form ... actually suppressing Not a problem, but just one side problem) 
 

You can change your ExternalTool like the following:

  class ExternalTool def label "# {vendor} # {product} v # {version}" and end  

When you set a variable in your controller:

< Pre> class SomeController & lt; ApplicationController def form_action @external_tools = ExternalTool.all end end

You can use it in your template:

  options_from_collection_for_select (@external_tools, " Take a note that, in its third argument, accepts the name of the  options_from_collection_for_select  name, "id", "label")  

Here we are using label in ExternalTool .

Hope that helps! Good luck!
