Question

I have this in models_name:

model_names = Object.constants.collect { |sym| Object.const_get(sym) }.select { |constant| constant.class == Class && constant.include?(Mongoid::Document) }.collect { |klass| klass.name }

the result is:

["Model_name1","Model_name2","Model_name3"]

I need something like:

[{"Model1":"Count"},{"Model2":"Count"},{"Model3":"Count"}]

I need show in a chart all models and object counter inside each model is working with morris.js

You can see the example:

Thank you very much!

Answer 1

that last one:

collect { |klass| klass.name }

rewrite it as

collect { |klass| [klass.name, klass.count] }

this should return an array of arrays of 2 elements (classname and count). If the variable to which this is assigned is called a, just do this:

Hash[a]

now you have a hash at your disposal. Now you can do this:

Hash[a].map do |k, v|
  {k => v}
end

and now you have an array of hashes of only one key-value assoc each. Which I think it is what you want.
