尝试迭代红宝石哈希时出现意外标签

Question

I am in the process of trying to iterate over a ruby hash. I'll have to admit that my knowledge of ruby is very poor and i am in the process of trying to correct that, and so please bear with me if this is a very elementary question.

I am wondering if the syntax of my hash is off. The reason why it is looking the way that it is is because it is part of a rakefile, and i need to incorporate multiple addresses in this. (which i've never done, i've always only had 1 address to worry about) I know the solution to this is to build the addresses in as a rakefile, and then loop over them.

clinic.build_address.each do | address, value |
                            {
                              (city: "Minneapolis"
                              state: "MN"
                              address1: "316 10th ave"
                              zip: "55414"),
                              (city: "Hudson"
                              state: "WI"
                              address1: "119 Belmont Street"
                              zip: "54016")
                            }
puts build_address

With what I have right now I am getting an unexpected label (it is not liking that I have 'city:minneapolis')

Would anybody be able to take a quick look at what I have with this?

Answer 1

If your Clinic model has an Address model related, and you run build_address , you won't end up with a hash, but an ActiveRecord object. However, I'm not sure what exactly your goal is.

To iterate a hash, you would use:

 
 
 
  
  some_hash.each do |key, value| # some logic using key and/or value end
 
  

Maybe you mean you want something like this:

 addresses = [ { city: "Minneapolis" state: "MN" address1: "316 10th ave" zip: "55414" }, { city: "Hudson" state: "WI" address1: "119 Belmont Street" zip: "54016" } ] addresses.each { |a| clinic.build_address a }

It's hard to understand what you are trying to do but your code is not a valid Ruby code. The closest I could get to is this:

{a: "b"}.each do | address, value |
  [
    {
      city: "Minneapolis",
      state: "MN",
      address1: "316 10th ave",
      zip: "55414"
    },
    {
      city: "Hudson",
      state: "WI",
      address1: "119 Belmont Street",
      zip: "54016"
    }
  ]
end
