Refactoring CSV Uploads with ActiveModel::Model Discussion
Awesome episode, Chris! Would be nice to continue with moving CSV parsing to a background job and adding ajax progress bar to provide visual feedback on import progress
Chris, I'm having trouble figuring out how to convert the date field in my csv file (mdY) to the proper format. It's reading the Y correctly, but importing the day to month and vice-versa instead of day to day and month to month. Where should the code be put and what does it look like? I tried a bunch of things and just can't get it to work. I looked at smarter_csv and thought that might be the answer, but it didn't work for me.
I believe there's a "converters" option that you can pass in. It basically tries to convert every column to a Date object and if it is successful, it will use that. You'd pass in the ":date" option for it (something like converters: [:date] I believe). You can read a bit more about that here: http://ruby-doc.org/stdlib-...
Plus if you have something custom that doesn't work with that, you can write your own converter. I just did this for a project and figured I should make an episode on it. Pretty nifty and easy to do, but really poorly documented.
Hey Chris - awesome stuff however, could I ask for a favor. I know some videos link to the github repo but would it be possible to have the code pasted also - sorta like how Ryan Bates had it. When you're trying to go through and connect the different parts or figure how things work its harder to keep going back and forth on the video trying to find the exact location.
Thoughts on the following gem: https://github.com/continuu...
This looks pretty cool. It might need some updates for newer versions of Rails since it hasn't been updated in a while, but you might check to see if anyone has been maintaining a fork.
Hey Chris, I made it all the way through and implemented this in EntityCloud, but my only issue seems to be that no matter which row in the CSV my error is on, the $. prints out "1". Any idea why this is not printing the correct line number? If there are multiple rows with errors they all print out as "1". Thanks!
What is the best approach to deal with csv headers that don't match 1:1 to the model's columns?
I used Structs to build a hash, but I'm thinking on refactoring to ActiveModel::Model.
Once you have the row as a Ruby hash, you can use transform_keys to modify the keys and renaming the CSV headers (keys) to the name you want.
