passing proper arguments to application controller

An application controller method requires two arguments generate_municipal_withins(municipal, radius) but in a separate controller action, calling this method is yielding

ArgumentError (wrong number of arguments (given 1, expected 2)):

from

@municipals.each do |municipal|
  generate_municipal_withins(municipal: municipal, radius: 70)

My assumption is that it is the former for if this is modified to generate_municipal_withins(municipal: municipal, 70) the same error is generated.

Thus it appears the member of the collection is not being passed as an argument. How should the syntax be fixed?

From the method definition, it tells the method is expecting to be called with two arguments, but you're using a single hash in:

generate_municipal_withins(municipal: municipal, radius: 70)

Doing method(municipal: municipal, radius: 70), is the same as method({municipal: municipal, radius: 70}), which is a single argument being a hash.

If your method is defined to use keyword arguments, then you could use the version shown in your question, but for that the method should be written as:

generate_municipal_withins(municipal:, radius:)
  ...
end

Try passing just municiapl and 70:

generate_municipal_withins(municipal, 70)
