Posted in Ruby question - Generating a nested hash with group_by

Thank you for this Chris, it has given me a way to rethink my approach. I will try it out. I may be back, but thank you very much.

Posted in Ruby question - Generating a nested hash with group_by

Thanks Chris. I was thinking I might need a nested hash because I will need to look up a specific month of a specific year and then delete the value.

hash = {
2017: {month: 1, value: 4583.33}, {month: 2, value: 4583.33}, {month: 3, value: 4583.33},{month: 4, value: 4583.33}, ... },
2018: {month: 1, value: 4583.33}, {month: 2, value: 4583.33}, {month: 3, value: 4583.33},{month: 4, value: 4583.33}, ... },
2019: {month: 1, value: 4583.33}, {month: 2, value: 4583.33}, {month: 3, value: 4583.33},{month: 4, value: 4583.33}, ... },
2020: {month: 1, value: 4583.33}, {month: 2, value: 4583.33}, {month: 3, value: 4583.33},{month: 4, value: 4583.33}, ... }
}

Like I mentioned, I don't even know if the nested hash is needed, but I need to identify specific months to remove them from the further calculation.

Thank you again in advance for any help to put me in a stronger direction.

Posted in Ruby question - Generating a nested hash with group_by

I'm trying to create a nested hash. I have a hash with the year as the key and an amount for that year. hash = {2017 => 55000, 2018 =>55500, 2019 => 60000}

I need to divide the amount for each year by 12 to create a nested has sorted by year and then the month and monthly amount. Once I have this larger hash I will need to go through the hash and delete certain month/amount pairs for each year.

Any recommendations on how best to approach this? I iterated over the key value to create the initial hash (to divide the month values by 12) and then used the group_by feature to create the nested hash, but the hash is too nested (an extra level deep) and I cannot sort out how to get this corrected.

I can be more specific, but wanted to seek out if there were better ways to approach this problem than what I've come up with. I have found tutorials I find on using group_by somewhat limiting. Any help or guidance is greatly appreciated. Thank you in advance.

Thank you for pointing me in this new direction.

Posted in Store a hash in a database

I have a calculator that takes yearly pension contributions into a hash. Therefore, everyone has a contribution lined up with a year. I don't want a database of dozens of years as one individuals contributions my start in 1970 while another's in 2000. I basically just want to keep the data stored in the hash it currently is in (I currently don't store this information in a database). Is hstore the best thing to look at or serialize or something else? Thank you in advance for all input.

Posted in Two Factor Authentication With Devise Discussion

I'm about 13 minutes into this tutorial and get a routing error.

No route matches {:action=>"show", :controller=>"two_factor"}, missing required keys: [:id]

I've checked and double checked my typing, but I often have routing errors.
